Description

Technical Field

[0001] The invention relates to a pole tower monitoring system and to the technical field of online monitoring of electric power equipment. Background Art

[0002] With the development of science and technology and the increase in power transmission, the number of transmission line towers in society is increasing day by day, and at the same time, the accompanying accidental safety accidents are also emerging in an endless stream. In recent years, accidents such as the collapse of transmission line poles and line disconnection have occurred frequently, which will not only cause a chain reaction in the power system, but also bring great losses to the national economy. In order to avoid the occurrence of tower collapse accidents, the monitoring system of the Internet of Things is usually used for monitoring. A transmission tower tilt monitoring and early warning system and method (publication number CN113701713A, public announcement date: 2021-11-26) discloses a transmission tower tilt monitoring and early warning system and method, including a data acquisition device, a wireless communication device, a server and a mobile terminal connected in sequence; sending real-time collected data to the server; the server is configured to compare and judge the collected transmission tower tilt angle and the settlement degree of the foundation under the transmission tower with the set threshold, and send the result to the mobile terminal. An online monitoring device is also disclosed in an online monitoring device and method for the attitude of a transmission and distribution line tower (publication number CN113670262A, public announcement date: 2021-11-19), which includes a first GNSS antenna, a second GNSS antenna, a positioning module, an MCU processor, etc. The data of the GNSS antenna is processed by the positioning module and sent to the satellite for attitude identification.

[0003] In these two methods of monitoring poles and towers, the use of Zigbee sensor networks leads to problems such as short transmission distance of the wide area network, difficulty in networking, large number of node deployment, and slow speed. Moreover, for application sites with complex and changeable coverage and natural environment and uneven distribution, traditional Zigbee can no longer meet the application requirements. GNSS is mainly responsible for positioning. If it is used to monitor the inclination angle of power poles and towers, the accuracy of monitoring the posture of the poles and towers is not high, so good real-time online monitoring cannot be achieved. In addition, the above two methods do not provide a good solution to the problem of data conflicts caused by multiple nodes in the wide area network sending data to the same node. Summary of the invention

[0004] The purpose of the present invention is to solve the problems of difficulty in networking of existing monitoring systems, easy collision or loss of transmitted data, resulting in low monitoring accuracy, and propose an online monitoring system for towers.

[0005] The tower online monitoring system includes multiple temperature sensors, multiple tilt sensors, multiple tower node boards, Lora sending modules, Lora receiving modules, tower gateway boards, NBoit modules, cloud platforms and mobile terminals.

[0006] Each power tower is equipped with a tilt sensor, a temperature sensor, a tower node plate and a Lora transmitter module.

[0007] Each tilt sensor is used to collect the tower angle, angular velocity and acceleration of the power tower in real time and transmit them to the tower node plate;

[0008] Each temperature sensor is used to collect the ambient temperature in real time and transmit it to the tower node plate;

[0009] Each tower node board is used to integrate the tower body angle, angular velocity, acceleration and ambient temperature received at the same time, obtain the integrated data, and convert it into hexadecimal data. After adding the address, channel and corresponding identification code to the hexadecimal data, the obtained sorted data is sent to the Lora receiving module through the Lora sending module, and the sorted data is sent to the tower gateway board through the Lora receiving module. After each sorted data reaches the set delay time, it is sent to the tower gateway board through the Lora sending module and the Lora receiving module;

[0010] The tower gateway board is used to remove the address and channel of each received sorted data, convert the obtained data into decimal data, parse the acceleration, angular velocity, angle and ambient temperature of the power tower body where the tower node board corresponding to the identification code is located from the decimal data, and report the acceleration, angular velocity, angle and ambient temperature to the cloud platform through the NBoit module;

[0011] Cloud platform for storing and displaying acceleration, angular velocity, angle and temperature;

[0012] The mobile terminal is used to receive acceleration, angular velocity, angle and temperature from the cloud platform for display.

[0013] The beneficial effects of the present invention are:

[0014] 1. Install GSP20 AIS10 inclination sensor, temperature sensor, STM32 microcontroller and Lora transmitter module on the power tower. The inclination sensor is used to measure the tower angle of the power tower in real time; the temperature sensor is used to measure the temperature difference between day and night; the STM32 microcontroller is used to receive data from the inclination sensor, on the one hand, store the data in the E2 chip for subsequent use, on the other hand, transmit the data from the tower node board to the tower gateway board, and is responsible for the energy supply of the entire measurement and transmission device.

[0015] The tower gateway board is responsible for uploading the inclination data, acceleration, temperature and other data transmitted from the tower node board to the cloud platform. The tower gateway board contains STM32 microcontroller, Lora receiving module and NBiot module. The STM microcontroller is responsible for receiving data, sending and receiving instructions, the Lora module is responsible for receiving data from the tower node, and the NBiot module is used to connect to the cloud platform and report data to the cloud platform for analysis.

[0016] The cloud platform uses China Mobile's ONENET IoT cloud platform to build an interface, which is responsible for real-time display of the tilt angle, vibration acceleration, and ambient temperature of the power tower. It has an alarm function for large angle changes and can issue commands to the tower gateway board. On the one hand, the cloud platform transmits the collected data to the big data platform, which can provide higher computing efficiency and implement large-capacity data storage in a large range. On the other hand, it transmits the data to the mobile terminal to observe the tilt status of the power tower anytime and anywhere. Real-time monitoring of the tilt angle of the power tower avoids accidents, with fast transmission rate and high accuracy.

[0017] 2. The GSP20 AIS10 inclinometer used is equipped with quaternion attitude solution and dynamic Kalman filter algorithm, which can accurately output the current attitude in harsh dynamic environments. The attitude measurement accuracy is 0.05°, the stability is extremely high, and the performance is even superior to some inclinometers.

[0018] 3. After obtaining data using the monitoring system of the present application, a mathematical model of tower inclination can be established to help analyze factors that affect the inclination of power towers, such as the structure of the power towers, settlement, wind speed, etc.

[0019] Mathematical model of tower tilt: The loads on the tower are divided into fixed loads and variable loads. Fixed loads are mainly the gravity loads of the tower, and the gravity of a specific tower is fixed. The influence on the tower tilt is expressed by a time function. Effectively analyze the factors that cause the collapse of the tower, and reasonably analyze and utilize the collected data.

[0020] 4. For the data transmission collision problem of multiple send and one receive in the wide area network, a node data anti-collision algorithm based on time slot ALOHA is proposed. The node collects the random number assigned by the gateway and delays the reporting of data to avoid channel conflicts caused by the simultaneous transmission of multiple data. That is, each sorted data obtained by the tower node board must reach the set delay time before being sent to the tower gateway board through the Lora sending module to prevent collisions caused by the simultaneous transmission of two or more sorted data, thus solving the problems of data loss and data confusion in multiple send and one receive.

[0021] 5. The design of the power-saving circuit and low-power mode of the tower node board and the tower gateway board can make the minimum current of the measuring device less than 20μA when in standby mode. Powered by a 5000mA lithium battery, the measuring device can work continuously for 2-3 years, solving the problem that the power tower cannot provide power.

[0022] 6. China Mobile Onenet Cloud Platform is a PaaS IoT open platform created by China Mobile. The platform can help developers easily access and connect devices, quickly complete product development and deployment, and provide a complete IoT solution for smart hardware and smart home products. By creating an NBiot module (the NBIot module is used to receive data and provide data to the cloud platform interface), it receives data from the tower gateway board, displays monitoring data in real time, and monitors the posture of the tower.

[0039] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0040] Specific implementation method 1: Combination Figure 1 and Figure 2 The present embodiment is described. The pole tower online monitoring system described in the present embodiment includes a plurality of temperature sensors 2, a plurality of inclination sensors 1, a plurality of pole tower node plates 3, a Lora sending module 4-1, a Lora receiving module 4-2, a pole tower gateway plate 5, an NBoit module 6, a cloud platform 7 and a mobile terminal 8.

[0041] Each power tower is equipped with a tilt sensor 1, a temperature sensor 2, a tower node plate 3 and a Lora sending module 4-1;

[0042] Each inclination sensor 1 is used to collect the tower angle, angular velocity and acceleration of the power tower in real time and transmit them to the tower node plate 3;

[0043] Each temperature sensor 2 is used to collect the ambient temperature in real time and transmit it to the tower node plate 3;

[0044] Each tower node board 3 is used to integrate the tower body angle, angular velocity, acceleration and ambient temperature received at the same time, obtain the integrated data, and convert it into hexadecimal data. After adding the address, channel and corresponding identification code to the hexadecimal data, the obtained sorted data is sent to the Lora receiving module 4-2 through the Lora sending module 4-1, and the sorted data is sent to the tower gateway board 5 through the Lora receiving module 4-2. After each sorted data reaches the set delay time, it is sent to the tower gateway board 5 through the Lora sending module 4-1 and the Lora receiving module 4-2;

[0045] The tower gateway board 5 is used to remove the address and channel of each received sorted data, convert the obtained data into decimal data, parse the acceleration, angular velocity, angle and ambient temperature of the power tower body where the tower node board 3 corresponding to the identification code is located from the decimal data, and report the acceleration, angular velocity, angle and ambient temperature to the cloud platform 7 through the NBoit module 6;

[0048] In this embodiment,

[0049] Through the cooperation of GSP20 AIS10 inclination sensor, Lora wireless communication and NBiot narrowband Internet of Things, data can be transmitted to the cloud platform for real-time monitoring. Fig.15 In the figure, the data at the node is collected every 6 seconds. It can be seen that the collection accuracy is 0.1°. It can meet the monitoring needs of most power towers, improve practicality, and facilitate promotion.

[0050] This application proposes a real-time online monitoring system based on GSP20 AIS10 tilt sensor, LORA networking communication technology, NBiot narrowband Internet of Things technology, and China Mobile cloud platform, so as to monitor the tilt angle of power poles and towers in real time online, with fast transmission rate and high accuracy. The status of the poles and towers can be checked at any time, and a node data anti-collision algorithm is proposed, which can perfectly solve the problems of data loss and data confusion caused by multiple transmissions and one reception.

[0051] This application provides a tower cloud platform online monitoring system, the working principle of the system is:

[0052] In the pole tower node board, the STM32F103C8T6 single-chip microcomputer is used as the MPU for controlling data transmission, sending commands, low power mode, data calculation, and data analysis. The analog signal collected by the GSP20AIS10 tilt sensor is converted into HEX16 after analog-to-digital conversion. After adding the address, channel, and identification code, it is transmitted to the Lora receiving module through the Lora sending module, and then transmitted to the pole tower gateway board. The pole tower gateway board converts the received hexadecimal data into decimal to obtain the real angular velocity, acceleration, angle, and temperature value, and transmits the obtained data to the cloud platform through the NBoit module 6. Among them, the conversion of the hexadecimal system is the existing technology, for example: HEX16 system, as follows:

[0053] 55 51 D8 01 C8 FF 83 06 32 F4 0D 55 52 F4 FF DF FF 3B 00 33 F4 DA 5553 25 FF 04 F6 FB EE 32 F4 CF

[0054] Among them, 55 identification code, 51 acceleration identification code, D8 01 X-axis acceleration, C8 FF Y-axis acceleration, 83 06 Z-axis acceleration, 32 F4 temperature, 0D checksum, similarly: 55 52 angular velocity, 55 53 angle.

[0055] After being sorted out by the tower node plate, the data is transmitted from the LORA module, and the data is as follows:

[0056] [11:12:54.185]Receive ←◆00 05 06 01 00 1C 55 51 C7 01 B6 FF A8 06 4C F412 55 52 0A 00 0D 00 00 00 4A F4 F2 55 53 A2 FE 71 F5 BF EF 45 F4 95

[0057] [11:12:56.272]Receive ←◆00 05 06 01 00 1B 55 51 39 02 AD FF 27 06 7C F41D 55 52 00 00 34 00 69 FF 7E F4 A8 55 53 3F FE 17 F3 85 F0 7E F4 E3

[0058] [11:12:57.316]Receive ←◆00 05 06 01 00 1C 55 51 F2 00 4B 00 4C 06 8E F4B7 55 52 4F 00 DE 00 B1 FE 90 F4 5D 55 53 A3 FF 7D F5 53 ED 8E F4 98

[0059] 00 05: Gateway board's LORA module address. 06: Channel. 01: Node 1 identification code. 00 1C battery power. 55 51 The same goes for both.

[0060] The data received by the tower gateway board is as follows:

[0061] 01 00 1C 55 51 C7 01 B6 FF A8 06 4C F4 12 55 52 0A 00 0D 00 00 00 4AF4 F2 55 53 A2 FE 71 F5 BF EF 45 F4 95

[0062] The data removes the address and channel.

[0063] Analysis:

[0064] The raw data transmitted to the gateway board needs to be converted into decimal real angular velocity, acceleration, angle, and temperature values.

[0065] The acceleration is expressed as follows from the decimal data:

[0066] ax=((AxH<<8)|AxL) / 32768*16g;

[0067] ay=((AyH<<8)|AyL) / 32768*16g;

[0068] az=((AzH<<8)|AzL) / 32768*16g;

[0069] In the formula, ax, ay and az are the acceleration values ​​of the X-axis, Y-axis and Z-axis respectively, AxH represents the high 8 bits of the X-axis acceleration in the sorted data, AxL represents the low 8 bits of the X-axis acceleration in the sorted data, (AxH<<8)|AxL) is the decimal number converted from the X-axis acceleration in the sorted data, AyH represents the high 8 bits of the Y-axis acceleration in the sorted data, AyL represents the low 8 bits of the Y-axis acceleration in the sorted data, (AyH<<8)|AyL) is the decimal number converted from the Y-axis acceleration in the sorted data, AzH represents the high 8 bits of the Z-axis acceleration in the sorted data, AzL represents the low 8 bits of the Y-axis acceleration in the sorted data, (AzH<<8)|AzL) is the decimal number converted from the Z-axis acceleration in the sorted data, and g represents the acceleration due to gravity. g is 9.8m / s2.

[0070] For example: C7 01=1100 0111 0000 0001, the 1 in 1100 is the sign, 1 is negative, and 0 is positive. 100 01110000 0001 is converted to decimal as 18177.

[0071] 18177 / 32768*16*9.8=86.98m / s2.

[0072] The angular velocity is expressed as follows from the decimal data:

[0073] wx=((wxH<<8)|wxL) / 32768*2000(° / s);

[0074] wy=((wyH<<8)|wyL) / 32768*2000(° / s);

[0075] wz=((wzH<<8)|wzL) / 32768*2000(° / s);

[0076] Wherein, wx, wy and wz are the angular velocity values ​​of the X-axis, Y-axis and Z-axis respectively, wxH represents the high 8 bits of the X-axis angular velocity in the sorted data, wxL represents the low 8 bits of the X-axis angular velocity in the sorted data, (wxH<<8)|wxL) is the decimal number converted from the X-axis angular velocity in the sorted data, wyH represents the high 8 bits of the Y-axis angular velocity in the sorted data, wyL represents the low 8 bits of the Y-axis angular velocity in the sorted data, (wyH<<8)|wyL) is the decimal number converted from the Y-axis angular velocity in the sorted data, wzH represents the high 8 bits of the Z-axis angular velocity in the sorted data, wzL represents the low 8 bits of the Z-axis angular velocity in the sorted data, (wzH<<8)|wzL) is the decimal number converted from the Z-axis angular velocity in the sorted data.

[0077] For angular velocity calculation, for example: 01 00 1C 55 51 C7 01 B6 FF A8 06 4C F4 12 55 520A 00 0D 00 00 00 4A F4 F2 55 53 A2 FE 71 F5 BF EF 45 F4 95

[0078] After converting 16 to decimal, remove the sign bit. 22FE = 8958, 8958 / 32768*180 = 49.21. Take 1 decimal place, which is 49.2 degrees. The sign bit is 1, a negative number, -49.2 is the actual value measured at this moment.

[0079] The angle is expressed by parsing the decimal data as follows:

[0080] Roll=((RollH<<8)|RollL) / 32768*180(°)

[0081] Pitch=((PitchH<<8)|PitchL) / 32768*180(°)

[0082] Yaw=((YawH<<8)|YawL) / 32768*180(°)

[0083] Wherein, Roll, Pitch and Yaw are roll angle, pitch angle and yaw angle respectively, RollH represents the high 8 bits of the X-axis angle in the sorted data, RollL represents the low 8 bits of the X-axis angle in the sorted data, (RollH<<8)|RollL) is the decimal number converted from the X-axis angle in the sorted data, PitchH represents the high 8 bits of the Y-axis angle in the sorted data, PitchL represents the low 8 bits of the Y-axis angle in the sorted data, (PitchH<<8)|PitchL) is the decimal number converted from the Y-axis angle in the sorted data, YawH represents the high 8 bits of the Z-axis angle in the sorted data, YawL represents the low 8 bits of the Z-axis angle in the sorted data, (YawH<<8)|YawL) is the decimal number converted from the Z-axis angle in the sorted data.

[0084] The power supply is through Figure 8 The TP4065 power management chip charges the lithium battery. The input circuit is 5V input. If you need to temporarily turn off the power, press Figure 7 Just press the power button K1. Figure 7 The button SW2 is a self-locking button, which is used to control the circuit power on and off, just like the TV power button, while K1 is a non-self-locking button. Pressing it will temporarily turn off the power, which is used for debugging.

[0085] Figure 5JI in the figure is the boot0 boot pin, and J2 is also the boot1 boot pin, which is used to control the startup switching between SRAM and Flash of STM32F103CBT6; boot0:0, boot1:X is Flash startup; boot0:1, boot1:0 is ISP startup; boot0:1, boot1:1 is SRAM startup.

[0086] After the data is collected, it can be stored in the E2 data storage chip, which is convenient for later use and secondary processing. Figure 5 The crystal oscillator X1 is a 32.768khz external crystal oscillator responsible for providing real-time time, the SWD interface is responsible for providing the STM32F103CBT6 main control chip with a program debugging interface, the crystal oscillator X2 is an 8M crystal oscillator responsible for providing high-speed crystal oscillator frequency, the external wake-up button and reset button are used for debugging the microcontroller, the button that controls the Lora module PIN1 and the button that controls the Lora module PIN2 are responsible for controlling the transmission mode of the Lora module, and the Lora module interface is responsible for connecting the SX1278Lora module for wide area network data transmission.

[0087] The tower gateway board is responsible for receiving data from the WAN tower node and reporting it to the cloud platform server for real-time monitoring. For the gateway board: the Micro USB interface is responsible for powering the gateway board and charging the lithium battery. Fig.12 The Ch340E chip is used to download programs and debug serial ports for the STM32F103CBT631 chip. For the main control STM32F103CBT6 chip, it is responsible for receiving the node board data from the Lora module, and then parsing the data. For hexadecimal data, it is divided by 32768 and multiplied by 180° to obtain the real angle data, acceleration (which can be converted into vibration), and temperature in the same way. Then it is copied to the buffer array defined by RXBUFF[], written into the AT command, and sent to the cloud platform through the NB module and SIM IoT card to send the ATNOTIFY command to display the data in real time. The power supply part is powered by a battery with a 1.25mm interface. The USB power switch and battery power switch are responsible for the power switch. The SWD interface is responsible for program download and debugging of the microcontroller STM32F103CBT6 chip. Fig.13 The GNSS antenna is used to send and receive positioning signals, the BOOT pin is used to determine the startup mode of the STM32F103CBT631 chip, and the RF antenna is used for the data transmission function of the NB module to enhance the signal. The Wake up button and the reset button can determine the standby and reset of the microcontroller, the alarm buzzer is used to remind the node tower collapse, and the Lora module is used to send commands.

[0088] After receiving the data, the cloud platform can display it in real time, send it to the database for data processing, or send it to the mobile terminal interface for viewing. This allows real-time monitoring of the tilt angle of the power tower to avoid accidents.

[0089] In this real-time mode, the Lora module is a wide area network, and the NBoit module is responsible for uploading data to the cloud platform, which is China Mobile's onenet IoT cloud platform. The identification code is used to identify the tower node board. For example, the identification code 01 is the data transmitted from the No. 1 tower node board, and 02 is the data transmitted from the No. 2 tower node board. Each tower node board corresponds to a transmission tower.
