The following briefly describes embodiments of the present invention by way of application examples, which are merely provided to illustrate embodiments of the present invention and are not intended to limit the scope of the present invention.
Application example
Fig. 7 is a schematic diagram of communication interaction of the sensor network according to this application, and as shown in fig. 7, the sensor network includes: the server, the sensor devices (device a, device B, device C and device D in the figure) are mobile terminals with wireless communication transceiving functions, and the application example communication interaction process comprises:
step 701, a server determines sensor equipment in a preset area and sends a reporting instruction for reporting equipment information to the sensor equipment through a mobile network; here, the sensor devices within the preset area may perform detection discovery through the mobile network.
Step 702, after receiving a report instruction, the sensor device sends device information to a server according to the report instruction; the device information may include basic information of the device such as an IP address, a remaining power, a signal strength, a location, etc.
In step 703, the server selects one of the sensor devices reporting the device information as a gateway according to the received device information.
Step 704, the server informs the selected gateway to the equipment in the network through the notification message;
step 705, the device elected as the gateway (assuming the gateway is device a) receives service data collected by other devices in the network;
step 706, the elected gateway receives the service data collected by other sensor devices in the network, and sends the received service data and the service data collected by itself to the server.
The application example sends the collected service data to the server in the mode of selecting the gateway, so that the problems of data confusion and the like caused by uploading the service data by a large number of sensor devices can be effectively avoided; the problems of large power consumption, long uploading time and the like caused by independent uploading of each sensor device can be avoided, and the efficient transmission of service data is realized.
In an exemplary embodiment, if the server receives service data of the gateway greater than a first preset duration, the server determines whether the gateway is interrupted, and if the gateway is interrupted, the process of re-electing the gateway is triggered.
When the network is initialized, all the sensor devices have the same electric quantity, but the distances from the sensor devices to the gateway are not always the same, so that the transmission rates of the sensor devices are different, and the energy consumption is also different. Assuming that the power consumption of uploading data to the platform by the device a through the mobile network is X1, the power consumption of uploading data to the platform by the device B through the mobile network is X2, and so on, the power consumption of uploading data to the platform by all the devices is X, that is, x=x1+x2+x3+x4, so that it can be seen that each sensor device independently uploads data information, and there will be great power consumption.
When the application example selects the gateway, the server needs to select the gateway according to the uploaded equipment information, so that the electricity consumption of the equipment is effectively balanced.
The application example can acquire the information of the residual electric quantity of the gateway, and when the residual electric quantity of the gateway is smaller than the preset electric quantity, the processing of issuing the report instruction is re-executed, and a new gateway is selected according to the newly received equipment information; in an exemplary embodiment, the present application example may further set a preset duration as a duration for re-electing the gateway, where the preset duration may be determined by a person skilled in the art through analysis according to parameters including a total power, a remaining power, and the like of the sensor device.
If the sensor equipment is selected as a gateway, receiving service data collected by other sensor equipment; if the gateway is replaced, the new gateway will replace the original gateway to receive and send service data, and when the sensor device is not operating as the gateway, the relevant information of the sensor device stored when the gateway receives the service data will be deleted.
According to the application example, the sensor equipment except the gateway can periodically collect service data and send the service data to the gateway, and other times can enter a dormant state to save electric quantity; the gateway may send the received traffic data to the server periodically. The application example reduces the electricity consumption of the rest of the sensor equipment by selecting the gateway and sending the service data of the rest of the sensor equipment through the gateway, and performs data transmission in a wireless mode, thereby improving the network energy efficiency and prolonging the life cycle of the sensor equipment.
Taking device a as a gateway for example. The server uploads, via all the sensor devices stored in the memory, the following: and determining that the equipment A is a gateway through set election rules by the equipment such as the residual electric quantity information, the signal intensity information, the gateway selecting times, the position information and the like. The server sends a notification to the device a, the device B, the device C and the device D that elects the device a to be a gateway. The device A receives the information of the gateway itself, and keeps the original function unchanged. After receiving the information that the gateway is the device A, the device B, the device C and the device D close the wide area wireless communication network (wireless module) and keep the local transmission network open, so that the situation that the sensor devices except the gateway independently upload service data to the server to cause confusion and resource waste of the uploaded data information is avoided, and low power consumption is realized.
When the sensor equipment works, equipment A, equipment B, equipment C and equipment D acquire service data, the equipment B, the equipment C and the equipment D periodically communicate with the equipment A serving as a gateway through local transmission, acquired data information is sent to the gateway equipment A through a low-power network of a local transmission network, the gateway equipment A sorts the self-acquired service data and the received service data from the equipment B, the equipment C and the equipment D and sends the service data to a server through a mobile network, and the server receives all the service data uploaded by the gateway equipment A.
If the server receives the data uploaded by the gateway device a, the following occurs: if the service data transmission is unsuccessful or the server responds to the data reception timeout, the server will make a detailed record of the occurrence of this situation.
If the server detects that the state of the gateway device a is a communication interruption (fail), or the gateway device a cannot periodically upload service data, the server will reselect a new gateway; or more than one of the equipment B, the equipment C and the equipment D, when the service data is transmitted to the gateway equipment A, the equipment B, the equipment C or the equipment D can start a wide area wireless communication network when detecting that the state of the gateway equipment A is communication interruption, send the state of the gateway equipment A to a server, detect the state of the gateway equipment A, reselect a new gateway when finding that the state of the gateway equipment A is communication interruption, and the selected new gateway equipment replaces the original gateway equipment A to periodically upload the service data. If the newly selected new gateway device is device B, the server will send a notification of the newly selected new gateway to devices a, B, C, and D in the same manner as the data receiving and sending of the original gateway device a. If the equipment A has the conditions of insufficient residual electric quantity or insufficient wireless network card expense and the like, the gateway can not be selected, but the collected service data can still be uploaded to the gateway through the local transmission network. The application example aims at the problems of gateway election and low circuit application efficiency, effectively improves the application efficiency of network resources and equipment electric quantity, and prolongs the operation period of the sensor network.
