As shown in Figure 3, the embodiment of the present invention provides a remote wake-up method applied to a device tag, including:

Step 301. Receive a first wake-up command, where the first wake-up command includes device identification information of a device to be woken up.

In this embodiment, the device label is the device label of the device to be woken up, and the first wakeup command may be a wakeup command sent by the stimulating device for device wakeup. The excitation device is, for example, an actuator. The device to be awakened is located within the excitation range of the excitation device. The first wake-up command includes device identification information of the device to be woken up.

Step 302: Perform wake-up verification on the device identification information and the tag identification information stored in the device tag.

Tag identification information is stored in the device tag, where the tag identification information is the identification information of the device to which the device tag belongs. After the device tag receives the first wake-up command, it performs wake-up verification according to the device identifier carried therein and the tag identifier stored in itself, and judges whether it needs to wake up the electronic device to which it belongs (that is, the device to be awakened).

Step 303 , if the wake-up verification is passed, send a wake-up signal to the low-power wake-up module of the device to be woken up.

In this embodiment, the device to be woken up includes the device label, and also includes a low-power wakeup module. The low-power wake-up module is used to wake up the device to be woken up, and the device tag can communicate with the low-power wake-up module through a general-purpose input/output (GPIO) interface. When the device tag determines that the device needs to be woken up, a wakeup signal is sent to the low power consumption wakeup module. The low power consumption wake-up module wakes up the device. The wake-up signal may be a high-level signal, such as "1".

In the embodiment of this application, after the device tag receives the first wake-up command from the exciter, it performs wake-up verification according to the device identification in the first wake-up command and the tag information stored in itself. The low-power wake-up module of the device to be woken up sends a wake-up signal, thereby waking up the device. It fully realizes resource saving and remote management of equipment, and solves the problem of time-consuming and inefficient on-site operations for operators when the equipment is in a harsh environment or the equipment is far away from the operating room.

Optionally, in the embodiment of the present application, the first wake-up command may be a read control (command) instruction sent by the incentive device to the device tag, such as a selection command, a query command, etc., the read control signaling The device wake-up indication function is added in , the format of the wake-up signaling can be added in the reserved free field of the control signaling, and the new signaling field can be used to indicate whether the device tag performs wake-up related operations. Optionally, the method further includes: determining whether to perform a wake-up verification operation according to the signaling field contained in the first wake-up command; performing wake-up verification on the device identification information and the tag identification information stored in the device tag , including: if the signaling field indicates to perform the wake-up verification operation, performing wake-up verification on the device identification information and the tag identification information stored in the device tag.

In this embodiment, after the device tag receives the first wake-up command, it judges whether to perform device wake-up according to the signaling field of the first wake-up command, and performs the wake-up verification operation when the device needs to be woken up. Specifically, the signaling field of the first wake-up command includes a wake-up bit for indicating whether to perform a wake-up verification operation and the device identification information; and according to the signaling field included in the first wake-up command, it is determined whether to perform Wakeup verification operation, including one of the following:

When the wake-up bit includes first bit information, determine to perform the wake-up verification operation;

When the wake-up bit includes the second bit information, determine not to perform the wake-up verification operation, and enter an inactivated state;

When the wake-up bit includes the third bit information, it is determined to perform a target number of wake-up verification operations.

In this embodiment, the signaling field of the first wake-up command may indicate whether to perform wake-up verification. When the wake-up bits contain different information contents, the indicated results are different. The filling of the wake-up bits may be as shown in Table 1.

Table 1: Padding description for wake-up bits.

As shown in Table 1, when the wake-up bit is "0×", the device tag only executes the command command and enters the Killed state; when the wake-up bit is "10", the device tag performs a wake-up verification operation and judges that it is to be woken up Whether the device ID of the device is consistent with its own storage tag ID, if consistent, the device tag can send a high-level signal (that is, the wake-up signal) to the low-power wake-up module through the GPIO interface; if inconsistent, the device The tag enters the killed state; when the wake-up bit is "11", the device tag conducts a secondary confirmation whether the device ID is consistent with the tag ID stored in itself. Send a high-level signal to ensure the execution of the wake-up operation, if inconsistent, the device tag enters the Killed state. In the above Table 1, "10" is the first bit information, and "0×" is the second bit information; taking the target number of times as 2 as an example, then "11" is the The third bit of information.

In this embodiment, taking the first wake-up command as the command command sent by the incentive device as an example, as shown in FIG. It includes two parts: a wake-up bit and device identification information, and the wake-up bit may include a main identification bit and a judgment bit. Wherein, the command command may include: a query request field (QueryReq), an acknowledgment (ACK), a query field (Query), a query correction field (QueryAdjust), a selection field (Select), an inactivation field (Killed), a locking field (Lock), an acquisition field (Access), and the reserved (Reserved) field. As shown in FIG. 4 , in the reserved field, a wake-up bit and a device identification information bit of the device to be woken up are newly added.

It should be noted that Table 1 and FIG. 4 are only exemplary descriptions of the contents of the signaling field of the first wake-up command, and the wake-up bit can also be set in other forms, which are not limited here.

A new low-power wake-up module is added, and it can automatically enter the low-power sleep mode after sending the wake-up trigger twice, which not only ensures the wake-up trigger between the tag and the device, but also ensures the need for long-term standby.

As an optional embodiment, the method further includes: receiving an excitation signal sent by an excitation device to which the device to be awakened belongs; sending a reflection signal to a receiving device to which the excitation device belongs according to the excitation signal, and the reflection signal Include the label identification information.

The receiving the first wake-up command includes: receiving the first wake-up command sent by the excitation device, the first wake-up command is for the receiving device to match the tag identification information with the device identification information of the device to be woken up Sent after sex verification.

In this embodiment, the inventory and wake-up of the operation and maintenance equipment can be managed by the Internet of Things (IOT) platform, and when the equipment needs to be awakened, the IOT platform sends the inventory and a certain A wake-up command of the device (which may be the second control signaling, which may include a device identification of the device to be woken up). After the receiving device receives the inventory and wake-up command of the IOT platform, it sends inventory information (which can be the first control signaling) to all downstream incentive devices in time-sharing; the incentive device sends the inventory information to the device tags within its incentive range according to the inventory information. An excitation signal: the device tag sends a reflection signal to the receiving device after receiving the excitation signal, and the reflection signal includes the tag identification of its own device (also the device identification of the device) stored in the device tag. Optionally, the reflected signal may further include information such as PC/EPC/CRC-16.

After the receiving device receives the reflected signal, it performs consistency verification according to the tag ID therein and the device ID of the device to be woken up sent by the IOT platform, and judges whether the device that needs to be woken up is within the excitation range of the current incentive device, if consistent If it means that the judgment is successful, the receiving device sends a second wake-up command to the stimulus device, and the second wake-up command is used to instruct the stimulus device to send the first wake-up command to the device tag to perform a device wake-up operation . Wherein, the second wake-up command can be consistent with the information contained in the first wake-up command, that is, it also includes the device ratio identification of the device to be woken up and the wake-up bit indicating whether to perform a wake-up verification operation, and the specific format of the wake-up bit I won't go into details here.

In the embodiment of the present application, the internal logical architecture of the device tag is shown in Figure 5, which may include a power management module (Power Management), a modulator/demodulator (Modulator/Demodulator), an oscillator (Oscillator), a tag A controller (TAG controller), a nonvolatile memory (Nonvolatile Memory) (NVM), etc., also includes a GPIO interface, and the device tag sends a wakeup signal to the low-power wakeup module through the GPIO interface, thereby realizing device wake.

Optionally, the device to be woken up includes a low-power wake-up module, which can be in a low-power sleep state for a long time. The low-power wake-up module enters the working state from the dormant state, executes the operation of waking up the device, and can start the device through Uart or RS232; optionally, after the wake-up is completed, the low-power wake-up module can enter the dormant state. The logical architecture of the low-power wake-up module is shown in Figure 6, and the working mode of the low-power wake-up module is shown in Figure 7, and the low-power wake-up module can monitor the wake-up signal in real time with low power consumption in the sleep state. It enters the working state after detecting the wake-up signal.

The low-power consumption wake-up module has advantages in the case where the equipment is located in a harsh environment and is not suitable for personnel operation, or the equipment is far away, and manual operation is time-consuming. Shutdown/restart instructions and operations can also be added correspondingly according to actual needs, which can realize remote wake-up or shutdown/restart of the device.

The implementation process of realizing the remote wakeup of the device by the remote wakeup method is described below through specific embodiments.

Taking the receiving device as a receiver and the stimulating device as an exciter as an example, as shown in Figure 8, it includes a device inventory phase and a device wake-up phase.

(1): Equipment inventory stage: scan and identify equipment labels.

The role of the equipment inventory stage is: the receiver sends control signaling to the exciter in a time-sharing manner, and confirms that the exciter where the equipment is located needs to be woken up by scanning and identifying the equipment label. The position of the device can also be reconfirmed through this stage when the exciter to which the device belongs is known.

As shown in Figure 8, in the equipment judgment stage, the IOT platform remotely realizes the inventory and wake-up of the operation and maintenance equipment. Wherein, the IOT platform issues an inventory and wake-up instruction (that is, the second control signaling) to the receiver; after receiving the inventory and wake-up instruction, the receiver sends a control signaling (that is, the second control signaling) to all its downstream exciters. The above-mentioned first control signaling), the control signaling is, for example, Query/Adjust/Req and the like. The actuator sends an excitation signal (such as Query/Adjust/Req, etc.) to the device tag.

The device tag sends a reflection signal to the receiver according to the excitation signal, and performs a handshake process; after the handshake is successful, the receiver sends a command command (that is, the second wake-up command) to the exciter, and the excitation The device sends a command command (that is, the first wake-up command) to the device tag to execute the device wake-up process.

(2) Device wake-up stage: device label verification and wake-up device.

The role of the device wake-up phase is: after the receiver confirms the exciter to which the device belongs, it issues a command command carrying a wake-up command (that is, the second wake-up command) to the exciter; the exciter sends a command command to the device tag (ie the first wake-up command).

After receiving the command, the device tag judges whether it needs to be woken up, that is, whether it needs to perform wake-up verification (whether to perform wake-up). Consistent, if consistent, then send a wake-up signal to the low-power wake-up module (can send a high-level signal to the low-power wake-up module through the GPIO interface), and the low-power wake-up module monitors the high-level signal, then enters Working state, and then wake up the device through Uart/RS232. Afterwards, the device tag executes command(handle) and enters the killed state. After the low-power wake-up module sends two wake-up information through Uart/RS232, it automatically enters the low-power sleep mode and waits for the next wake-up trigger.

If the device label does not need to execute the wake-up operation according to the signaling field of the command command, the device label enters the Killed state; or if the device label only executes the command command according to the signaling field of the command command, it enters the Killed state after executing the command command. state.

In the embodiment of the present application, the framework for implementing the above-mentioned remote wake-up method is a separate RFID framework, as shown in FIG.

At the same time, with the help of the energy conversion brought about by the continuous emission of the tag excitation signal, the device tag can perform inventory and wake-up instruction judgment operations, and Send a high-level signal to the device that needs to be woken up after judging success. The second is to make full use of the idle field of the command command Reserved to add wake-up signaling. On the basis of not changing the existing RFID transmission protocol, realize the carrying of wake-up commands and device ID information. At the same time, through the target number of times (for example, twice) confirmation mechanism , to ensure accurate realization of the wake-up. The third is to realize the monitoring of the wake-up trigger signal in the low-power mode by adding a low-power wake-up module, and automatically transfer to the low-power sleep mode after the wake-up trigger is sent twice, which not only ensures the communication between the device label and the device The wake-up trigger in between, and ensure the demand for long-term standby. This application fully realizes resource saving and remote management, and is especially effective for the equipment in harsh environments, or the equipment is far away from the operating room outdoors, and the operator's on-site operation is time-consuming and inefficient.
