[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] Example 1:

[0031] This embodiment provides a tunnel supervision robot, such as Figure 1 As shown, it includes a main control unit, an environmental monitoring unit 5, a measurement unit, an alarm unit 6, a positioning unit 4, a communication unit, a monitoring unit 1, a human-computer interaction unit, and a voice intercom unit 2, which are electrically connected.

[0032] The environmental monitoring unit 5 is used to collect environmental monitoring data inside the tunnel and send the environmental monitoring data to the main control unit;

[0033] The positioning unit 4 is used to acquire the location data of the supervision robot in the tunnel and send the positioning data to the main control unit;

[0034] The main control unit is used to receive and process environmental monitoring data sent by the environmental monitoring unit 5, to receive and process positioning data sent by the positioning unit, and to receive and process measurement data sent by the measurement unit. Then, it outputs the processed environmental monitoring data, positioning data, and measurement data through the communication unit, and sends an alarm signal to the alarm unit when the environmental monitoring data and measurement data exceed the threshold, so that the alarm unit can perform an alarm operation.

[0035] In this embodiment, a tunnel supervision robot replaces manual supervision, acquiring environmental monitoring data, positioning data, and measurement data within the tunnel. This data is then output to the user terminal in real time via a communication unit, enabling remote monitoring by supervisors. This allows for unmanned operations such as inspections, on-site monitoring, and settlement monitoring and measurement. Simultaneously, it can send alarm signals to the alarm unit when environmental monitoring and measurement data exceed thresholds. This embodiment uses automated data measurement to replace manual labor, effectively reducing the workload of supervisors, lowering the cost of manual supervision, and reducing the risks to supervisors in high-risk and complex construction sites, thus effectively ensuring their personal safety.

[0036] In this embodiment, as Figure 3 As shown, the main control unit includes a controller U3, and a programming interface H1, a serial port H2, a main control status indicator LED23, a reset module, and a crystal oscillator module that are electrically connected to the controller U3. The controller U3 is implemented using a 32-bit microcontroller based on the ARM Cortex-M core STM32 series, model STM32F103C8T6. Its program memory capacity is 64KB, it requires a voltage of 2V to 3.6V, and its operating temperature is -40℃ to 85℃, making it suitable for harsh environments such as tunnels.

[0037] It should be understood that the environmental monitoring unit and alarm unit are all electrically connected to the controller U3 in the main control unit through a switch module.

[0038] In this embodiment, as Figure 4As shown, the switching module includes an N-type MOSFET Q2, an optocoupler U2, a transistor Q4, a relay RLY1, and a mounting interface U1. The optocoupler U2 is an IS3H7C type, and the relay RLY1 is an SRD-05VDC-SL-C type. The gate of the N-type MOSFET Q2 is electrically connected to the main control unit via a thirteenth resistor R13. The junction between the gate of the N-type MOSFET Q2 and the thirteenth resistor R13 is grounded via a twentieth resistor R20. The source of the N-type MOSFET Q2 is grounded, and the drain of the N-type MOSFET Q2 is electrically connected to the second pin of the optocoupler U2. The first pin of the optocoupler U2 is electrically connected to the fourth pin of the optocoupler U2 via a twelfth resistor R12. The twelfth resistor R12 is connected in parallel with a seventeenth resistor R17. The fourth pin is the power supply pin of the switching module. The third pin of optocoupler U2 is electrically connected to the base of transistor Q4 through the eighteenth resistor R18. The base of transistor Q4 is also grounded through the nineteenth resistor R19. The emitter of transistor Q4 is grounded. The collector of transistor Q4 is electrically connected to the fourth pin of relay RLY1. The fourth pin of relay RLY1 is electrically connected to the first pin of relay RLY1 through the freewheeling diode D3. The freewheeling diode D3 is connected in parallel with a series circuit consisting of the fourteenth resistor R14 and the light-emitting diode LED1. The first pin of relay RLY1 is also connected to the power supply pin of the switching module through the eleventh resistor R11. The eleventh resistor R11 is connected in parallel with the sixteenth resistor R16. The second, third, and fifth pins of relay RLY1 are all electrically connected to the mounting interface U1.

[0039] In this embodiment, the controller U3 of the main control unit is electrically connected to the gate of the N-type MOS transistor Q2 through resistor R13 to send a switch drive signal to the switch module. When the controller U3 outputs a high level, the LED inside the optocoupler U2 lights up, driving the phototransistor inside the optocoupler U2 to conduct, which in turn causes the transistor Q4 to saturate and conduct, energizing the coil of the relay RLY1. The environmental monitoring unit and alarm unit, which are electrically connected to the mounting interface U1, then start operating. It should be noted that when relay RLY1 is disconnected, due to its inductive characteristics, a freewheeling current will occur, generating a very high voltage spike on the relay RLY1 coil, which could damage transistor Q4. The freewheeling diode D3 prevents the electromotive force from acting back on transistor Q4, thus protecting transistor Q4 and preventing it from burning out. In addition, optocoupler U2 further isolates controller U3 from relay RLY1, preventing the electromotive force generated by the disconnection of relay RLY1 from affecting the normal operation of controller U3. Transistor Q4 can act as a secondary amplifier, making the operation of optocoupler U2 more sensitive, thereby enhancing the driving capability of optocoupler U2 for relay RLY1.

[0040] In this embodiment, the communication unit adopts a wired communication module or a wireless communication module. The communication unit is used for communication between various terminals to realize short-range or long-range data interaction and further meet application requirements. The wired communication module includes a network port CN1 electrically connected to the controller U3. The circuit diagram of network port CN1 is shown below. Figure 5 As shown, the wireless communication module can be, but is not limited to, any one of a WiFi transceiver module, a Bluetooth transceiver module, and a GPRS transceiver module, or any combination thereof. The WiFi transceiver module can also be used for WiFi positioning to facilitate real-time monitoring of the tunnel supervision robot's location.

[0041] In this embodiment, the alarm unit uses a rotating strobe alarm light (model LTE-1101J) with a 24V signal warning light. It has a specially designed rainproof and dustproof shell, making it suitable for harsh environments. It also uses a rotating high-intensity reflector, which can easily alert surrounding users to avoid the robot.

[0042] In this embodiment, the environmental monitoring data includes oxygen concentration data, light intensity data, dust concentration data, and combustible gas concentration data. The environmental monitoring unit includes an oxygen sensor for collecting oxygen concentration data, a light intensity sensor for collecting light intensity data, a dust concentration sensor for collecting dust concentration data, and a combustible gas sensor for collecting combustible gas concentration data. All the oxygen sensor, light intensity sensor, dust concentration sensor, and combustible gas sensor are electrically connected to the main control unit. In this embodiment, the alarm unit can issue an alarm when the oxygen concentration data, light intensity data, dust concentration data, and combustible gas concentration data exceed corresponding thresholds, thereby facilitating timely evacuation for construction personnel inside the tunnel.

[0043] In this embodiment, the oxygen sensor is a VMS-3002-O2 oxygen sensor, which is made of high-quality high-density material, has a built-in waterproof strip, has a significant moisture-proof effect, and is equipped with a high-precision probe with an imported chip built in, which can effectively improve the measurement accuracy.

[0044] The light intensity sensor uses a digital light intensity sensor model GY-302, which uses the original ROHM BH1750FVI chip. The sensor has a built-in 16-bit AD converter, which can directly output digital data, eliminating the need for complex calculations and calibration. It has a spectral characteristic close to visual sensitivity and can measure a wide range of brightness with a high precision of 1 lux.

[0045] The dust concentration sensor uses the GP2Y1014AU model dust sensor, which has extremely low current consumption (maximum 20mA, typical 11mA) and can be equipped with sensors up to 7VDC. It can output an analog voltage proportional to the measured dust concentration and has good sensitivity.

[0046] The combustible gas sensor uses the FZN-3001-MU-LEL model and is used to detect the concentration of combustible gases such as coal gas, liquefied petroleum gas, and natural gas. It is small in size, light in weight, easy to install, and has the characteristics of high resolution, high sensitivity, and fast response speed. It also has a built-in temperature compensation function, adopts intrinsically safe circuit design, and has strong anti-interference ability.

[0047] In this embodiment, the measurement unit employs a self-developed active laser module. The laser module consists of a control board, a 4G module, a level, an arch measurement laser, a level measurement laser, a battery, and a wireless module. It can obtain settlement convergence values ​​in real time and communicate via wired, 4G, or wireless methods. This module is an active settlement convergence monitoring module that uses a fully automated mode to collect tunnel settlement and convergence values ​​around the clock. Integrating multiple intelligent algorithms, this module can replace manual total station detection methods and is of significant importance in railway tunnel construction, operation, and maintenance.

[0048] The active laser module uses two laser ranging sensors that form a fixed angle θ between them. The value of θ is set according to different tunnels. When measuring the tunnel deformation value, the laser module is fixed to the tunnel sidewall. The value of θ is determined through field testing, so that the light from laser sensor 1 hits the top surface of the tunnel, and the light from laser sensor 2 hits the tunnel sidewall horizontally.

[0049] Laser emitter 1 collects the hypotenuse length y, and laser emitter 2 collects the base length x. The h value is calculated using formula (1), and x is used as the base length. k (k = 1, 2, 3, ..., n) represents the length of the tunnel bottom edge obtained in the k-th sampling. Similarly, y k h represents the length of the hypotenuse obtained in the k-th sampling. k The value represents the k-th calculation. The settlement convergence value of the tunnel cross section at point 1 can be obtained using formulas (2) and (3), where X represents the tunnel convergence value and H represents the tunnel settlement value.

[0050] h k =y k sinθ (1)

[0051] X = x k -x k-1 (2)

[0052] H = h k -h k-1 (3)

[0053] In this embodiment, the tunnel supervision robot further includes a monitoring unit, which includes a monitoring unit for collecting environmental video data and a lighting unit for providing illumination when the monitoring unit is collecting environmental video data. Both the monitoring unit and the lighting unit are electrically connected to the main control unit.

[0054] In this embodiment, the monitoring unit uses an infrared night vision camera from Hikvision, which is equipped with an explosion-proof housing, resulting in a longer service life and making it suitable for engineering scenarios such as tunnels. In this embodiment, four sets of cameras are installed, located at the front, left, right, and front of the robot body, respectively. The lighting unit provides light for the robot during standby and inspection processes, ensuring the safety of the entire robot's movement and improving the clarity of the environmental video data collected by the camera unit.

[0055] In this embodiment, the tunnel supervision robot further includes a human-machine interaction unit, which includes a display unit and a voice broadcasting unit. Both the display unit and the voice broadcasting unit are electrically connected to the main control unit. The main control unit is also used to send the processed environmental monitoring data and positioning data to the display unit and the voice broadcasting unit, so that the display unit can display the environmental monitoring data and positioning data, and the voice broadcasting unit can broadcast the environmental monitoring data and positioning data.

[0056] The voice broadcasting unit can broadcast information such as distance and construction status when the robot patrols key points in the tunnel. It can also broadcast pre-stored voice and text content about project overview and construction status to help construction personnel in the tunnel.

[0057] In this embodiment, the tunnel supervision robot further includes a voice intercom unit electrically connected to the main control unit. The voice intercom unit receives first voice data sent by construction personnel inside the tunnel and transmits it to the main control unit. The main control unit receives and processes the first voice data sent by the voice intercom unit and outputs it through a communication unit. The main control unit also receives and processes second voice data sent by the communication unit and outputs it through the voice intercom unit. It should be noted that the second voice data is sent by the supervision personnel, who can remotely communicate with construction personnel inside the tunnel via the voice intercom unit to understand the construction progress. The display unit can display environmental monitoring data collected by the environmental monitoring unit in real time, allowing construction personnel or supervision personnel to quickly understand the situation inside the tunnel.

[0058] In this embodiment, the tunnel supervision robot further includes a positioning unit, which is electrically connected to the main control unit. The positioning unit is used to acquire equipment tag information in the tunnel and send the tag information to the main control unit.

[0059] It should be understood that the main control unit, environmental monitoring unit 5, alarm unit 6, positioning unit, communication unit, monitoring unit 1, display unit, voice broadcasting unit 2, voice intercom unit 2, and positioning unit 4 are all powered by the power supply unit. In this embodiment, the circuit diagram of the power supply unit is as follows: Figure 6 As shown.

In this embodiment, the remote control terminal can be a handheld remote control and visual integrated terminal. During implementation, supervisors can control the tunnel supervision robot's forward, backward, turning, and obstacle avoidance actions through the remote control terminal.
