[0020] Those skilled in the art will understand that the accompanying drawings are merely schematic diagrams of exemplary embodiments, and the modules or processes in the drawings are not necessarily necessary for implementing this disclosure, and therefore cannot be used to limit the scope of protection of this disclosure.

[0021] like Figure 1 As shown, embodiments of this disclosure provide a coupled monitoring system for environmental parameters in a thermal power plant, including a mobile monitoring terminal 100, a communication base station 200, and a central control terminal 300. Figure 2 As shown, the mobile monitoring terminal 100 includes a drive module 110, an environmental monitoring module 120, and a communication module 130. The drive module 110 drives the mobile monitoring terminal 100 according to mobile control commands. The environmental monitoring module 120 acquires environmental parameters. The communication module 130 sends the environmental parameters and receives the mobile control commands. The central control terminal 300 sends the mobile control commands and receives the environmental parameters. The communication base station 200 is communicatively connected to both the communication module 130 and the central control terminal 300.

[0022] Specifically, the central control terminal 300 regulates the overall operation, generates movement control commands to set the automatic inspection route of the mobile monitoring terminal 100 or remotely control the real-time movement of the mobile monitoring terminal 100, and sends the movement control commands to the communication base station 200. The communication base station 200 enables two-way communication between the mobile monitoring terminal 100 and the central control terminal 300, sending movement control commands to the communication module 130 of the mobile monitoring terminal 100. The drive module 110 drives the mobile monitoring terminal 100 to move in real-time according to the movement control commands received by the communication module 130, or to move along a preset automatic inspection route. The environmental monitoring module 120 acquires environmental parameters around the mobile monitoring terminal 100, then sends these parameters to the communication base station 200 via the communication module 130, and finally the central control terminal 300 receives and records them.

[0023] For example, such as Figure 3 As shown, the drive module includes a drive motor and two sets of track devices 31. The drive motor is used to drive each of the track devices 31. The two sets of track devices 31 are respectively disposed at the top and bottom of the mobile monitoring terminal 32, and each of the track devices 31 is parallel to the central axis 33 of the mobile monitoring terminal 32.

[0024] Specifically, two sets of four tracked devices 31 are distributed at the upper left, lower left, upper right, and lower right positions of the mobile monitoring terminal 32. Each tracked device 31 has a built-in drive wheel connected to a drive motor as the primary means of movement for the mobile terminal. The drive motor is a PMSM permanent magnet synchronous motor, and an FOC driver is used to control the two sets of tracked devices 31 to support the movement of the mobile monitoring terminal 32 and control its direction of travel. Tracked devices 31 are installed at the top and bottom of the mobile monitoring terminal 32, so that its normal operation is not affected even when it is upside down.

[0025] For example, such as Figure 2 As shown, the environmental monitoring module 120 includes a noise monitoring module 121, an air quality monitoring module 122, an air temperature and humidity monitoring module 123, and a camera 124.

[0026] Specifically, the XM7903 noise monitoring module, MQ135 air quality monitoring module, and DHT11 air temperature and humidity monitoring module are integrated with an OV7670 camera located at the front end of the mobile monitoring terminal to form an environmental monitoring module 120. This module monitors the noise level, air quality, air composition, air temperature and humidity around the mobile monitoring terminal, and the camera captures real-time images of the area in front of the mobile monitoring terminal. These environmental parameters are collected and ultimately uploaded to the central control terminal. Correspondingly, the central control terminal can be equipped with a flame detection module, which uses image algorithms to determine whether there is an open flame in the real-time image. It can also perform real-time image rendering and display on the received real-time image data.

[0027] For example, the communication module adopts the AS-DTU33(433M) LoRa communication module. Correspondingly, the communication base station can adopt the RG-IBS6120(E) LoRa communication base station for bidirectional transmission of communication signals between the mobile monitoring terminal and the central control terminal.

[0028] For example, the main control terminal is a DCS terminal computer of a thermal power plant, in which LoRa communication software and a DCS control and monitoring screen are installed. By setting the action logic of the mobile monitoring terminal in the DCS terminal computer and loading control command signals into the LoRa communication software, which then sends them to the mobile monitoring terminal via a communication base station, remote control of the mobile monitoring terminal's actions is achieved. Environmental parameter data uploaded by the mobile monitoring terminal via the communication base station is sent to the DCS terminal computer via the LoRa communication software, enabling remote real-time monitoring of the mobile monitoring terminal.

[0029] For example, such as Figure 2 As shown, the mobile monitoring terminal also includes a GPS module 140, used to send the location information of the mobile monitoring terminal to the communication module 130, and then the communication module 130 sends it to the communication base station. Correspondingly, the main control terminal is also used to receive the location information from the communication base station to obtain the accurate location of the mobile monitoring terminal in real time, and to calculate and process the location and future direction of movement of the mobile monitoring terminal.

[0030] For example, such as Figure 2 As shown, the mobile monitoring terminal also includes an anti-rollover module 150, which includes a gyroscope 151 and a hydraulic rod 152. The gyroscope 151 is disposed inside the mobile monitoring terminal, and the hydraulic rod 152 is disposed through both sides of the mobile monitoring terminal.

[0031] Specifically, the mobile monitoring terminal vehicle body is equipped with an electro-hydraulic rod 152 that runs through the left and right sides of the vehicle body, and has a built-in gyroscope 151 to detect the vehicle body tilt angle. When the vehicle body tilt angle reaches a preset threshold, the corresponding side of the hydraulic rod 152 extends to flatten the vehicle body to prevent the mobile monitoring terminal vehicle body from overturning, or to bounce the vehicle body up to flip the vehicle body.

[0032] For example, such as Figure 2 As shown, the mobile monitoring terminal also includes a main control module 160. The main control module 160 is electrically connected to the drive module 110, the environmental monitoring module 120, the communication module 130, and the anti-rollover module 150, respectively.

[0033] Specifically, the main control module 160 can use an STM32H743 microcontroller to perform preliminary calculations and processing of data collected by the environmental monitoring module 120. This data is then transmitted to the main control terminal via the communication module 130 through a communication base station. Simultaneously, the main control module 160 receives motion control commands from the main control terminal in real time and controls the drive module 110 to perform corresponding actions based on these commands. It also processes data from the gyroscope 151 in the anti-rollover module 150. When the tilt angle of the mobile monitoring terminal reaches a preset threshold, the main control module 160 controls the hydraulic rod 152 to extend from the corresponding side, preventing the mobile monitoring terminal from rolling over or causing the vehicle to bounce and overturn.

[0034] For example, such as Figure 2 As shown, the mobile monitoring terminal also includes a power module 170. The power module 170 is detachably mounted on the mobile monitoring terminal and is used to supply power to the mobile monitoring terminal.

[0035] Specifically, the power module 170 can use a Swift 18000mAh 12S lithium battery to power the various modules in the mobile monitoring terminal, and it is removable and rechargeable.

By collecting environmental parameters through a mobile monitoring terminal and transmitting the data to a central control terminal, it realizes intelligent coupled monitoring of environmental parameters within the thermal power plant. This system can conduct inspections and investigations of dangerous areas while ensuring personnel safety. It achieves real-time, comprehensive, safe, three-dimensional, all-round, and integrated monitoring of conventional areas of thermal power plants, and solves the personnel safety risk problem in the inspection and detection of dangerous areas under unexpected circumstances.

[0037] It is understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of this disclosure, and this disclosure is not limited thereto.
