[0002] The secondary operation of a transformer substation has accounted for 50% of the whole station operation, but so far, the correctness of platen operation cannot be monitored by automation; since the correctness of the platen position directly affects the correctness of the action of the automation device such as relay protection, and further affects the safe and stable operation of the power system.

[0003] At present, there are mainly two methods: one is visual information recognition, including unmanned aerial vehicle patrol and the like, and in actual use, the optical environment is required to be high, and a camera, a trolley and the like need to be installed. The second is a method of leading out a switching quantity, the platen state is obtained by monitoring the switching quantity, and this method leads out a connection from each switching quantity, a large amount of connection cables are needed, the complexity of the secondary circuit is increased, and the actual application is relatively troublesome.

[0004] Therefore, it is necessary to provide a super-low-power platen position monitoring Lora networking method to solve the above problems. SUMMARY

[0006] To achieve the above-mentioned purpose, the application provides the following technical scheme: a super-low-power platen position monitoring Lora networking method comprising the following steps:

[0007] Firstly, a sensor module, a Lora host and a cloud platform are sequentially connected in signal, the sensor module comprises a low-discharge battery, a sensor, a low-power processor and a Lora module, the sensor uses a displacement sensor and is used for detecting the position change of the outlet platen of a relay protection screen cabinet;

[0009] Thirdly, when the sensor module is connected in signal with the Lora host for the first time, the sensor module communicates with the Lora host and is registered in the Lora host, and then the sensor module is allocated with an address and a data update time given by the Lora host;

[0010] The fourth step is that the sensor module updates the state in time and sends the self-information to the Lora host. When the information of multiple sensor modules occurs at the same time, the Lora host arranges according to the importance, and processes the sensor module information of the main position, the secondary position and the irrelevant position in turn.

[0011] The fifth step is that the Lora host processes the received sensor module information, and delivers the processed data to the cloud platform.

[0012] The sixth step is that when the sensor module is offline or fails, the Lora host sends an error signal to reconnect. If the connection fails, the node of the pressure plate sensor is automatically deleted.

[0028] In the prior art, there are mainly two methods for monitoring the pressure plate. One is visual information recognition, including unmanned aerial vehicle patrol, etc. In actual use, the optical environment requirement is high, and a camera, a trolley, etc. need to be installed. The second is the method of leading out the switch quantity, obtaining the pressure plate state by monitoring the switch quantity. This method leads out the connection from each switch quantity, which requires a large number of connection cables, increases the complexity of the secondary circuit, and is relatively troublesome in actual application.

[0029] Therefore, the present application provides an ultra-low power pressure plate position monitoring lora networking method as shown in Figs. 1-3 which can reduce energy consumption and more simply monitor the purpose in time. Specifically, it includes the following steps:

[0030] S1, sequentially connect the sensor module, Lora host and cloud platform, the sensor module includes a low discharge battery, a sensor, a low-power processor and a Lora module, the sensor uses a displacement sensor for detecting the position change of the outlet pressure plate of the relay protection screen cabinet;

[0031] The Lora module is a wireless communication module based on Lora module technology. The Lora module technology uses spread spectrum modulation technology to spread data signals into a wider frequency band for transmission, thereby increasing the transmission distance and improving the anti-interference ability of the signal. This technology is particularly suitable for Internet of Things applications and can maintain good penetration and anti-multipath fading ability in a strong interference environment.

[0032] Therefore, the application uses the Lora module for transmission, which can realize remote transmission of several kilometers or even tens of kilometers, and is very suitable for Internet of Things application scenarios that require long-distance communication. The Lora module itself is designed with low power consumption and can operate stably for a long time under battery power supply, thereby reducing energy consumption and maintenance costs.

[0033] Moreover, the pressing plate does not need to be replaced frequently, and therefore is more suitable for monitoring using the Lora module.

[0034] S2, the sensor module is installed at the outlet pressing plate of the relay protection screen cabinet for monitoring the position of the pressing plate. Multiple sensor modules are provided, and the multiple sensor modules are respectively installed on multiple outlet pressing plates. According to the positions of the outlet pressing plates of different importance, the importance of each sensor module is arranged, and the importance is arranged in turn as a main position, a secondary position and an irrelevant position.

[0035] The sensor module can use a displacement sensor to detect the position information of the pressing plate and monitor the state of the pressing plate.

[0036] S3, in the first signal connection between the sensor module and the Lora host, the sensor module communicates with the Lora host and is registered in the Lora host after registration. The address and data update time provided by the Lora host are allocated.

[0037] S4, the sensor module updates the state regularly and sends its own information to the Lora host. When multiple sensor modules simultaneously generate information, the Lora host processes the sensor module information of the main position, the secondary position and the irrelevant position in turn according to the importance arrangement.

[0038] S5, the Lora host processes the received sensor module information and delivers the processed data to the cloud platform.

[0039] Each sensor module is sequentially numbered according to the importance arrangement order. The main position is the first sequence, the secondary position is the second sequence, and the irrelevant position is the third sequence. The priority of the Lora host receiving the sensor module information is in turn the first sequence, the second sequence and the third sequence. The sequence number of the sensor module is used as the identification of the sensor module.

[0040] Specifically, if there are multiple sensor modules in the first sequence, they can be labeled as 001, 002, 003, etc. in turn, multiple sensor modules in the second sequence can be labeled as 011, 012, 013, etc. in turn, and multiple sensor modules in the third sequence can be labeled as 111, 112, 113, etc. in turn.

[0041] The data collected by the sensor modules in each sequence number are sent to the Lora host respectively, and the Lora host data is stored. At the same time, the monitoring data of the sensor modules in the first sequence is preferentially sent, for example, when the sensor modules in the first sequence, the second sequence and the third sequence collect information and send it within the same time period (within 0-3 seconds), the sensor modules in the first sequence can be preferentially sent to collect information and feedback to the cloud platform, so that the monitoring personnel can operate through the cloud platform, and then the sensor modules in the second sequence and the third sequence collect information and are sent in turn.

[0042] Further, when the Lora host sends the first sequence, the second sequence and the third sequence to the cloud platform, the information of different sequences can be displayed in different colors for reminding personnel, so that personnel can operate in time, and monitoring is more secure and convenient.

[0043] If the sensor modules in the three sequences do not change in the same time period, the monitoring information is normally sent.

[0044] Since there are a large number of pressure plates in the transformer substation, multiple sensor modules are set, and the importance level of the pressure plate position monitored by the sensor modules is divided, so that the Lora host can preferentially determine which sensor modules need to be preferentially transmitted to the cloud platform, so that personnel can perform the first priority operation and monitoring, and avoid causing greater losses.

[0045] Based on the lora networking technology, and using low-power sensor modules, low-power, long-distance transmission, low cost, short time without replacement and repair of sensors can be achieved.

[0046] S6, when the sensor module is offline or fails, the Lora host sends an error signal, reconnects, and automatically deletes the node of the pressure plate sensor when the connection fails.

[0047] The sensor module includes a low-discharge battery, a sensor, a low-power processor and a Lora module. The signal output end of the sensor is connected to the signal receiving end of the low-power processor, the signal output end of the low-power processor is connected to the signal receiving end of the Lora module, the sensor is used to detect the change of the pressure plate, and the Lora module is connected to the Lora host.

[0048] Low-power sensor can enter sleep mode when there is no signal change, when there is external signal change, low-power processor stops sleeping and starts working, detects sensor signal and processes, then sends signal to Lora module, sends signal to Lora host through Lora signal, Lora host transmits signal to cloud platform, and waits for processing.

[0049] Lora host sends sensor module information to cloud platform through RS485 network interface.

[0050] The sensor uses a low-power sensor or a sleep low-power sensor, such as a passive sensor, a mechanical sensor, and a non-electric quantity driven sensor.

[0051] The sensor module is provided with a plurality of sensor modules, and the plurality of sensor modules are signal-connected with the Lora host.

[0052] The low-discharge battery is connected with the sensor, the low-power processor and the Lora module through wires respectively, and the low-discharge battery can be stored for more than 10 years, ensuring the long-term maintenance-free characteristics of the sensor.
