As a result, the application of IoT technology in agriculture or forestry can achieve new improvements in productivity and production efficiency.

Precious plants, also known as rare plants, refer to the species of plants that are of great significance in economy, science, culture and education but are sparsely extant. The protection of precious and rare plants is an important part of nature protection. However, at present, the price of some precious plants (such as golden nanmu, etc.) can easily be in the millions. If it is stolen or lost, it will be a very big loss for the plant grower or manager. However, the protection of precious plants has always brought many difficulties to managers. For example, due to the rugged terrain in the wild, managers cannot conduct on-site monitoring in real time; secondly, because the forest area is too large, it is impossible to count precious plants at any time.

In order to further achieve the purpose of terminal battery energy saving, the aforementioned working method of the individual wireless monitoring system for precious plant protection may also include specific working methods of the wireless terminal, base station and background server as shown below.

(1) The specific working method of the wireless terminal includes a sleep mode and an awakening mode, wherein the sleep mode may, but is not limited to, include the following steps S101:

S101. After it is determined to enter the sleep mode, the micro-control circuit unit and the wireless transceiver circuit unit enter an energy-saving working state, and at the same time, the micro-control circuit unit controls the power amplifier enable output terminal PAEN to output a first level signal, so that the power amplifier power supply control The power supply output terminal VPA of the circuit unit outputs a low-level voltage, and the half-duplex transceiver power amplifier circuit and the antenna unit are powered off and shut down.

In the step S101, whether to enter the sleep mode is determined by the micro-control circuit unit according to the actual situation. Once the sleep mode is entered, both the micro-control circuit unit and the wireless transceiver circuit unit will maintain the most basic energy-saving state. At the same time, the half-duplex transceiver power amplifier circuit and the antenna unit will be powered off without loss of energy consumption, so that a large amount of power can be saved in the sleep phase.

In addition, the awakening mode may include, but is not limited to, the following steps S201-S205.

S201. After it is determined to enter the wake-up mode, the micro-control circuit unit and the wireless transceiver circuit unit enter a normal working state, and at the same time, the micro-control circuit unit controls the power amplifier enable output terminal PAEN to output a second level signal, so that the power amplifier power supply control The power supply output terminal VPA of the circuit unit outputs a high-level voltage, and the half-duplex transceiver power amplifier circuit and the antenna unit are powered on to work.

In the step S201, whether to enter the wake-up mode is determined by the micro-control circuit unit according to the actual situation. Once the wake-up mode is entered, both the micro-control circuit unit and the wireless transceiver circuit unit will resume normal operation, and then read The individual health record data from the health sensor is stored, and the half-duplex transceiver power amplifier circuit and antenna unit will be powered on and ready to receive or transmit air interface messages at any time.

S202. The half-duplex transceiver power amplifier circuit and the antenna unit are controlled by the micro-control circuit unit to enter the simplex receiving state through the wireless transceiver circuit unit: if the terminal wake-up message from the base station is received on the wake-up channel on schedule, then step S203 is performed in sequence ~S205, otherwise it is determined to enter the sleep mode.

In the step S202, the terminal wake-up message is a dedicated air interface message from the base station and used to wake up intermittent dormant terminals (that is, the wireless terminals in this embodiment). Sending is performed in the following manner: continuously and periodically sending a plurality of the terminal wake-up messages on the wake-up channel within the first time period, wherein the terminal wake-up message includes the duration information of the first time period and the current message sending clock information, so The first period duration information is used to indicate the duration t of the first period, and the current message sending clock information is used to indicate the time stamp t _x from the start time of the first period to the current message sending time. Through the foregoing information configuration, the intermittent dormant terminal can know the end time of sending the terminal wake-up message in the current round after acquiring the information on the duration of the first period and the sending clock information of the current message, and then can set a longer Temporary sleep time (ie tt _x ) to perform timed sleep (ie enter a short sleep mode), directly sleep until the end of the transmission and then wake up (ie enter the wake mode again), which is beneficial for the terminal to save energy. In addition, the wake-up channel is a dedicated channel in the air interface dedicated to transmitting terminal wake-up related messages (including but not limited to the terminal wake-up message).

Specifically optimized, the duration t of the first period is greater than the sleep cycle T of the intermittently dormant terminal, and the sleep cycle T includes the periodic sleep duration _Tsleep and the periodic wake-up duration _Twake of the intermittently dormant terminal, and the terminal wake-up message The transmission period of the wireless terminal is less than the period T _wake of the wireless terminal. Through the aforementioned duration setting, it can be ensured that the intermittently dormant terminal can completely receive the terminal wake-up message within the wake-up duration of any sleep cycle, thereby preventing the occurrence of wake-up omissions. For example, if the periodic wake-up duration T _wake is 100ms, and the periodic sleep duration T _sleep is 3900ms, the sleep cycle of the intermittent dormant terminal is 4 seconds, and the transmission cycle can be designed to be 60ms (assuming that the terminal wakes up). The message sending time is 50ms, and the time slot interval of 10ms is reserved), and the first period can be designed to be 4020ms, so that the terminal wake-up message can be sent 67 times continuously.

Specifically optimized, to wake up all intermittent dormant terminals, the terminal wake-up message can be designed as a broadcast message. At this time, for intermittent dormant terminals, it is not necessary to know the sender's identity and/or identity of the terminal wake-up message. identity of the receiver, so the terminal wake-up message may further include invalid source address bits and/or invalid broadcast address bits, wherein the invalid source address bits are used to indicate that there is no source address information in the terminal wake-up message, The broadcast address invalid bit is used to indicate that there is no broadcast address information in the terminal wake-up message, the source address information is used to indicate the sender identity of the terminal wake-up message, and the broadcast address information is used to indicate the The identity of the recipient of the terminal wake-up message. The default configuration of the address of the aforementioned terminal wake-up message can effectively shorten the message length (generally 4 bytes or 8 bytes) and the sending time, which not only helps the message sender save energy, improves the channel utilization, but also effectively shortens the gap. The periodic awakening duration of the dormant terminal is further conducive to the energy saving of the terminal.

Optimized, considering that the forest area is large and there may be hundreds or thousands of precious plants, in order to reduce the probability of air interface collision during the competitive upload process of many subsequent data upload messages, so that the base station can quickly obtain all data upload messages, you can pass The terminal wake-up message guides the wireless terminals to perform autonomous grouping, so that they upload messages in parallel on different data channels, that is, in the step S202, if the terminal wake-up message also includes terminal grouping indication The control circuit unit determines the terminal group in which it belongs according to the terminal grouping indication information. Wherein, the terminal grouping indication information is used to help the wireless terminal to determine the terminal grouping where it is located. For further optimization, if the terminal grouping indication information is the number of terminal groups, the micro-control circuit unit applies the terminal grouping number to be unique to the local terminal The ID number in the identification information performs remainder calculation, and then determines the terminal group where it belongs according to the remainder calculation result. Of course, other methods can also be used to help the wireless terminal to determine the terminal grouping by itself, for example, according to the last number of the terminal ID number. Since the wireless terminal can determine its own terminal group and only feed back the inventory data on the data channel corresponding to the terminal group, a large number of wireless terminals can be divided into different channels for data upload, so as to achieve the purpose of concurrently uploading data and reducing the probability of collision , which can quickly complete the inventory task of all wireless terminals. For example, for a plant inventory scene in a forest area where there are 1000 wireless terminals, the number of terminal groups can be designed to be 4, and then the massive terminals can be divided into 4 groups, each group theoretically has 250 wireless terminals, and make them in Competitively uploading data and uploading messages on 4 different data channels, thereby realizing the purpose of 4-channel parallel data transmission and reducing the probability of collision. In addition, a dedicated channel different from the wake-up channel can be selected for the data channel, and the corresponding relationship between the data channel and the terminal group can be defaulted through a standard protocol, or can be specified in the terminal wake-up message, for example, for a terminal with a remainder of 0 For grouping, the first data channel is designated; for terminal grouping with remainder 1, the second data channel is designated; for terminal grouping with remainder 2, the third data channel is designated, and so on.

S203. Package the locally stored terminal unique identification information into a data upload message.

Before the step S203, when the terminal wake-up message also includes the upload task unique identifier and temporary sleep duration information, after wirelessly receiving the terminal wake-up message, the micro-control circuit unit will send the message according to the upload The task unique identification information determines whether the corresponding individual health record data upload task has been completed. If it is determined that the task has been completed, it is determined to enter a temporary sleep mode according to the temporary sleep duration information. In this way, the subsequent steps S203 to S205 may not be performed, so as to avoid repeated message uploading, and realize timely sleep, which is further beneficial for the terminal to save energy.

S204. The micro-control circuit unit controls the half-duplex transceiver power amplifier circuit and the antenna unit to enter the simplex transmission state through the wireless transceiver circuit unit: send the data upload message to the base station through the channel competition mechanism on the data channel.

In the step S204, if the wireless terminal has determined the terminal grouping in which it is located through the terminal grouping indication information, it needs to send the data upload message in the following manner: on the data channel corresponding to the terminal grouping in which it is located, through the channel competition mechanism The data upload message is sent to the base station. The data channel is a dedicated channel in the air interface dedicated to transmitting a message related to uploading data (including but not limited to the data uploading message), which may be the same as or different from the wake-up channel.

S205. The half-duplex transceiver power amplifier circuit and the antenna unit are controlled by the micro-control circuit unit to enter the simplex receiving state through the wireless transceiver circuit unit: if the data upload confirmation corresponding to the data upload message is not received on time on the confirmation channel message, it is determined that the transmission fails, and then returns to step S204 to resend the data upload message, until the number of retransmissions of the data upload message reaches the maximum number of retransmissions, and finally determines to enter the sleep mode, otherwise it is determined that the transmission is successful, and directly determines to enter the sleep mode model.

In the step S205, the acknowledgment channel is a dedicated channel in the air interface dedicated to transmitting transmission acknowledgment related messages (including but not limited to the data upload acknowledgment message), which may be the same as the wake-up channel or the data channel , can also be different. In another optimization, if the data upload confirmation message includes the second temporary sleep duration information, after the wireless terminal wirelessly receives the data upload confirmation message, the micro-control circuit unit determines the second temporary sleep duration information according to the second temporary sleep duration information. Enter temporary sleep mode. Since the wireless terminal sends the data upload message through the channel competition mechanism, there is a phenomenon that the reception fails due to collision risk, etc. It is necessary to inform the terminal whether the reception is successful. The configuration of sleep duration information informs the duration that wireless terminals that have completed data uploading can immediately enter the sleep mode. The specific duration can be set, but not limited to, based on the estimated duration of the inventory of all uploading terminals. Since there is no need to wake up again and feed back individual information within the preset time period (this time period is used to complete the inventory task of other terminals that have not been inventoried), it can not only reduce a large number of data upload messages over the air interface, but also achieve the purpose of reducing the probability of message collision. Completing the data uploading tasks of all wireless terminals can also make the wireless terminals enter a long sleep state to avoid unnecessary energy consumption, which is ultimately beneficial for the terminal to save energy and prolong battery life.

Therefore, through the detailed steps of the sleep mode and the wake-up mode, the wireless terminal can be further urged to make full use of various unnecessary wake-up time slots to perform sleep energy saving in the process of uploading individual information, so as to achieve the best energy saving purpose.

(2) The specific working method of the base station may, but is not limited to, include: after wirelessly receiving the terminal inventory start message from the background server, entering the terminal inventory mode: wirelessly sending the terminal wake-up message on the wake-up channel, and sending the terminal wake-up message through the wake-up channel. The listening data channel receives the data upload message from the wireless terminal, and feeds back the data upload confirmation message corresponding to the data upload message to the wireless terminal on the confirmation channel, and finally combines the unique identification information of the local base station with the unique identification information of the terminal in the data upload message. Bind and upload to the background server.

The generation method of the terminal inventory start message may be generated by manual intervention, or may be generated automatically at regular intervals, and needs to include base station address information (which may be the same as or different from the unique identification information of the base station), wherein the base station The address information is used to indicate the base station that needs to enter the terminal inventory mode immediately, and then the base station determines whether the base station address information matches the local base station address. The terminal unique identification information from each wireless terminal, and the collected terminal unique identification information is uploaded to the background server. Optimized, in order to improve the running speed of the base station and avoid data redundancy, it also includes the following: when the base station enters the terminal inventory mode, clears the local cached data, and feeds back to the background server a successful message of the terminal inventory startup. In addition, in order to avoid repeated startup of the inventory task, it is optimized that, before ending the terminal inventory mode, if the base station receives a terminal inventory startup message from the background server again, it will feed back a terminal inventory startup failure message to the background server, wherein the terminal inventory The startup failure message contains an indication that it has been inventoried. In this way, the background server can be informed that the terminal inventory is currently in progress, and there is no need to restart it repeatedly.

Optimized, if the terminal inventory start message also includes inventory mode indication information, when the inventory mode indication information indicates the long inventory mode, the base station ends the terminal inventory mode immediately after receiving the terminal inventory end message from the background server, When the inventory mode indication information indicates the fast disk mode, the base station periodically ends the terminal inventory mode according to the inventory duration information in the terminal inventory start message or ends the terminal inventory mode immediately after receiving the terminal inventory end message from the background server. . The inventory mode indication information is used to indicate whether the base station enters the long-run mode or the fast-run mode: (1) After the base station enters the long-run mode, the base station will continuously collect the terminal unique identification information from the wireless terminal and return it to the background server. , and stop until receiving the terminal inventory end message (the generation method of which can be consistent with the terminal inventory start message); (2) the base station will periodically collect the terminal unique identifier from the wireless terminal after entering the fast disk mode. The information is returned to the background server, and it stops (that is, it can end in advance) when the countdown (countdown or forward) reaches the inventory count time or after receiving the terminal inventory end message. Through these two modes, terminal inventory can be carried out regularly or irregularly to meet flexible application requirements.

In addition, the method of binding the unique identification information of the local base station with the unique identification information of the terminal in the data upload message and uploading to the background server can be set in advance in the terminal inventory start message, that is, optimized, the The terminal inventory start message contains data return indication information, then when the data return indication information indicates that data is returned directly, the base station periodically binds the local base station unique identification information with the newly received terminal unique identification information and uploads it to the terminal. The background server, and when the data return indication information indicates data read return, after receiving the data read request message from the background server, the base station binds the unique identification information of the local base station with the unique identification information of the terminal received in the cache upload to the backend server.

Optimized, after entering the terminal inventory mode, the base station also periodically counts the message packet loss rate of each data channel, and then obtains the information about the uploading terminal in each terminal group according to the mapping relationship between the message packet loss rate and the number of uploading terminals. Estimate the number, then determine the first terminal group with the largest number of uploading terminals and the second terminal group with the smallest number of uploading terminals, and finally send a terminal grouping change message on the wake-up channel and/or the confirmation The grouping corresponds to each data channel one-to-one, and the terminal grouping change message includes the grouping unique identifier of the first terminal grouping, the grouping unique identifier of the second terminal grouping, and the shared information of some wireless terminals belonging to the first terminal grouping. Special logo. Since the message packet loss rate is largely caused by message collision, the mapping relationship between the message packet loss rate and the number of unuploaded terminals can be obtained through routine experiments. The mapping relationship can be a mapping relationship between a pair of numerical ranges. For example, for a message packet loss rate of 0-1%, the corresponding number of unuploaded terminals may be 0-50; for a message packet loss rate of 2-3%, the corresponding number of unuploaded terminals may be 100-200. In addition, the estimated number and estimated remaining upload time can also be obtained through routine experiments. In addition, the shared special identifier may be, but not limited to, the last digit of the terminal ID number.

Further optimized, in order to enable the wireless terminal that has not completed the data upload to change the group by itself according to the terminal grouping change message, and achieve the purpose of grouping equalization, after the wireless terminal enters the simplex receiving state, if it receives the terminal grouping change message. , then the micro-control circuit unit determines whether the ID number in the unique identification information of the local terminal matches the shared special identification. If it is determined to match, then according to the grouping unique identification of the first terminal grouping and the second terminal group The unique group identifier of the terminal is changed from the first terminal group to the second terminal group. Therefore, through the aforementioned method, some wireless terminals can be divided from a large number of first terminal groups into a small number of second terminal groups, speeding up the inventory progress of the wireless terminals in the first terminal group, and realizing the final and rapid completion of all the wireless terminals. Inventory tasks for wireless terminals.

Further optimization, in order to enable the wireless terminal that has not completed the data upload to know the number of uploading terminals in the group of the terminal group, so as to dynamically set the backoff time for sending data upload messages through the channel competition mechanism, so that the base station can send the terminal wake-up message, Before the data upload confirmation message or the terminal group change message, the group unique identifier of each terminal group and the estimated number of uploading terminals in the group are added to the to-be-sent terminal wake-up message, data upload confirmation message or terminal group change message. In this way, after the wireless terminal enters the simplex receiving state, if it receives a terminal wake-up message containing the group unique identifier of each terminal group, the estimated number of terminals being uploaded in the group, and a data upload confirmation that does not correspond to the data upload message. message or terminal grouping change message, the micro-control circuit unit can determine the estimated number of uploading terminals in the group of the terminal grouping according to the grouping unique identifier, and then update the setting according to the estimated number to send the backoff of the data uploading message through the channel competition mechanism time. Wherein, the specific way for the wireless terminal to update and set the back-off time according to the estimated number may be: setting a longer current back-off time or maximum back-off time when the estimated number is large, and setting a shorter back-off time when the estimated number is small The current back-off time or the maximum back-off time, thus, by dynamically setting the back-off time, it is further beneficial to reduce the message packet loss rate and quickly complete all data upload tasks.

Optimized, if the data is uploaded concurrently, there is a situation where multiple data upload messages are successfully received at the same time. In order to reduce the time for the wireless terminal to listen to the confirmation channel and save energy for the terminal, it is necessary to perform parallel confirmation, that is, to further optimize, so The data upload confirmation message includes the terminal unique identification information of the multiple wireless terminals, and further, the same message frame can be used to confirm the data reception to the multiple wireless terminals.
