Description

Technical Field

[0001] The present invention relates to the field of pressure plate monitoring, and in particular to a Lora networking method for ultra-low power consumption pressure plate position monitoring. Background Art

[0002] Secondary operations of substations have accounted for 50% of the total station operations, but so far, the correctness of the pressure plate operation has not been automatically monitored; because the correctness of the pressure plate position directly affects the correctness of the operation of automation devices such as relays, which in turn affects the safe and stable operation of the power system.

[0003] There are two main methods at present: one is visual information recognition, including drone inspections, etc. In actual use, it has high requirements for the optical environment and requires the installation of cameras, cars, etc. The second is the method of leading out the switch quantity, which obtains the state of the pressure plate by monitoring the switch quantity. This method leads the wiring from each switch quantity, requires a large number of wiring cables, increases the complexity of the secondary circuit, and is more troublesome in actual application.

[0004] Therefore, it is necessary to propose an ultra-low power pressure plate position monitoring lora networking method to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to provide an ultra-low power consumption platen position monitoring lora networking method to solve the problem that a large number of wiring cables are required to lead out wiring from each switch quantity, which increases the complexity of the secondary circuit and is troublesome in practical application.

[0006] To achieve the above purpose, the present invention provides the following technical solution: an ultra-low power consumption platen position monitoring lora networking method, comprising the following steps:

[0007] The first step is to connect the sensor module, Lora host and cloud platform in turn. The sensor module includes a low-discharge battery, a sensor, a low-power processor and a Lora module. The sensor uses a displacement sensor to detect the position change of the outlet pressure plate of the relay protection panel cabinet.

[0008] The second step is to install the sensor module at the outlet pressure plate of the relay protection panel cabinet to monitor the position of the pressure plate. Multiple sensor modules are set, and multiple sensor modules are respectively installed on multiple outlet pressure plates. According to the outlet pressure plate positions of different importance, each sensor module is arranged in importance, and the importance arrangement is primary position, secondary position and irrelevant position;

[0009] Step 3: When the sensor module connects to the Lora host for the first time, it communicates with the Lora host and is assigned the address and data update time given by the Lora host after registering with the Lora host.

[0010] Step 4: The sensor module updates its status regularly and sends its own information to the Lora host. When multiple sensor modules send information at the same time, the Lora host arranges them according to their importance and processes the sensor module information of the primary position, secondary position and irrelevant position in turn.

[0011] Step 5: The Lora host will process the received sensor module information and transmit the processed data to the cloud platform;

[0012] Step 6. When the sensor module is offline or fails, the Lora host sends an error signal and reconnects. If the connection fails, the node of the pressure plate sensor is automatically deleted.

[0013] Each sensor module is numbered in order of importance, with the primary position being the first sequence, the secondary position being the second sequence, and the irrelevant position being the third sequence. The priority of the Lora host receiving the sensor module information is the first sequence, the second sequence, and the third sequence.

[0014] The serial number of the sensor module is used as the identification of the sensor module.

[0015] The data collected by the sensor modules in each sequence number are sent to the Lora host respectively, and the Lora host stores the data. At the same time, the monitoring data of the sensor modules in the first sequence are sent preferentially.

[0016] Preferably, 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, and the Lora module is signal-connected to the Lora host.

[0017] Preferably, the Lora host sends the sensor module information to the cloud platform via the RS485 network port.

[0018] Preferably, the Lora host sends the sensor module information to the cloud platform through the RJ45 network port.

[0019] Preferably, the sensor uses a low-power consumption sensor or a dormant low-power sensor.

[0020] Preferably, the sensor modules are provided in plurality, and all of the plurality of sensor modules are connected to the Lora host for signal connection.

[0021] Preferably, the low-discharge battery is connected to the sensor, the low-power processor and the Lora module respectively through wires.

[0022] Technical effects and advantages of the present invention:

[0023] 1. By setting up multiple sensor modules, the outlet pressure plates of multiple relay protection cabinets can be monitored at the same time, with low cost. By dividing the importance level of the pressure plate positions monitored by the sensor modules, the Lora host can prioritize which sensor modules need to be transmitted to the cloud platform, so that personnel can perform first-priority operations and monitoring, reduce personnel judgment time, improve efficiency, and avoid greater losses.

[0028] In the prior art, there are two main methods for monitoring the pressure plate. One is visual information recognition, including drone inspections, etc. In actual use, it has high requirements for the optical environment and requires the installation of cameras, cars, etc. The second is the method of leading out the switch quantity, which obtains the pressure plate status by monitoring the switch quantity. This method leads the wiring from each switch quantity, requires a large number of wiring cables, increases the complexity of the secondary circuit, and is more troublesome in actual application.

[0029] Therefore, the present invention provides Figure 1 to Figure 3 An ultra-low power consumption platen position monitoring lora networking method is shown, which can reduce energy loss and achieve simpler time monitoring purposes, specifically, including the following steps:

[0030] S1. Connect the sensor module, Lora host and cloud platform in sequence. The sensor module includes a low-discharge battery, a sensor, a low-power processor and a Lora module. The sensor uses a displacement sensor to detect the position change of the outlet pressure plate of the relay protection panel cabinet.

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

[0032] Therefore, the present invention uses the Lora module for transmission, which can achieve long-distance transmission of several kilometers or even tens of kilometers, and is very suitable for IoT application scenarios that require long-distance communication. The Lora module itself adopts a low-power design and can operate stably for a long time when powered by a battery, reducing energy consumption and maintenance costs.

[0033] And the pressure plate does not need to be replaced frequently, so it is more suitable for monitoring using the Lora module.

[0034] S2. Install the sensor module at the outlet pressure plate of the relay protection panel cabinet to monitor the position of the pressure plate. Multiple sensor modules are provided, and the multiple sensor modules are respectively installed on multiple outlet pressure plates. According to the outlet pressure plate positions of different importance, each sensor module is ranked in importance, and the importance is ranked in the order of primary position, secondary position and irrelevant position;

[0035] The sensor module may use a displacement sensor to monitor the state of the pressure plate by detecting the position information of the pressure plate.

[0036] S3, the third step, when the sensor module is connected to the Lora host for the first time, it communicates and interacts with the Lora host, and after registering with the Lora host, it is assigned the address and data update time given by the Lora host;

[0037] S4, the sensor module updates the status regularly and sends its own information to the Lora host. When multiple sensor modules send information at the same time, the Lora host arranges them according to importance and processes the sensor module information of the main position, secondary position and irrelevant position in turn;

[0038] S5, the Lora host will process the received sensor module information and transmit the processed data to the cloud platform;

[0039] Each sensor module is serially numbered in order of importance, with the primary position being the first sequence, the secondary position being the second sequence, and the irrelevant position being the third sequence. The Lora host receives the sensor module information in the order of priority of the first sequence, the second sequence, and the third sequence, and uses the serial number of the sensor module as the identification of the sensor module.

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

[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 of the first sequence are sent first. For example, when the sensor module collection information of the first sequence, the second sequence and the third sequence are sent in the same time period (within 0-3 seconds), the sensor module collection information of the first sequence can be sent first and fed back to the cloud platform, so that the monitoring personnel can operate through the cloud platform, and then send the sensor module collection information of the second sequence and the third sequence in turn;

[0042] Furthermore, 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 to remind personnel, so that they can operate in time and make monitoring safer and more convenient.

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

[0044] As there are a large number of pressure plates in the substation, multiple sensor modules are set up and the pressure plate positions monitored by the sensor modules are divided into importance levels. The Lora host prioritizes which sensor modules need to be transmitted to the cloud platform, so that personnel can perform first-priority operations and monitoring to avoid greater losses.

[0045] Based on lora networking technology and using low-power sensor modules, it can achieve low power consumption, long-distance transmission, low cost, and no need to replace or repair sensors in a short time.

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

[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, and 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 changes in the pressure plate, and the Lora module and the Lora host are connected by signal.

[0048] The low-power sensor can enter sleep mode when the signal does not change. When the external signal changes, the low-power processor stops sleeping and starts working, detects and processes the sensor signal, and then sends the signal to the Lora module, which is sent to the Lora host through the Lora signal. The Lora host passes the signal to the cloud platform and waits for processing.

[0049] The Lora host sends the sensor module information to the cloud platform through the RS485 network port. The Lora host sends the sensor module information to the cloud platform through the RJ45 network port.

[0050] The sensor uses a low-power sensor or a dormant low-power sensor. Low-power sensors include passive sensors, mechanical sensors and other non-electrically driven sensors.

[0051] There are multiple sensor modules, and all of them are connected to the Lora host for signal connection.

[0052] The low-discharge battery is connected to the sensor, low-power processor and Lora module through wires. The low-discharge battery can be stored for more than 10 years, ensuring that the sensor is maintenance-free for a long time.
