[0001] The utility model relates to but is not limited to the technical field of highway tunnels, and in particular to a highway tunnel ventilation monitoring and control device. Background Art

[0002] Tunnel technology is a method that uses a tunnel controller system to centrally control the environmental parameters in each section of the tunnel. Due to the special environment of the tunnel, long length, poor ventilation and other constraints, harmful gases in the tunnel need to be removed and ventilated in time. Once the concentration of harmful gases is too high, vehicles entering the tunnel will need to be in a harmful gas environment for a long time, which can easily cause poisoning or accidents.

[0003] For example, the highway tunnel ventilation monitoring system based on ARM of Chinese patent publication number CN204436477U performs ventilation monitoring through tunnel ventilation status monitoring units arranged in the monitored highway tunnel, and the control device is fixed in the tunnel. When the machine needs to be maintained in the later stage, workers need to enter the tunnel. If a car enters the tunnel and stops for maintenance, it will affect the traffic in the tunnel, and there are certain limitations in its use. Therefore, a highway tunnel ventilation monitoring control device that is easy to maintain is designed. Utility Model Content

The controller 1 is screwed on both sides with handles 104, which is convenient for holding the controller 1 when maintaining it.

[0031] In addition, tunnel ventilation monitoring may also use CO sensors, VI sensors (used to detect VI concentration in the tunnel), wind direction sensors, and vehicle flow sensors to comprehensively monitor environmental parameters and traffic conditions in the tunnel.

[0032] In this embodiment, the driving seat 201 is screwed to the upper surface of the moving base 3, a motor 205 is arranged between the driving seat 201 and the moving arm 202, a motor 205 is arranged between the moving arm 202 and the connecting arm 203, and the motor 205 is respectively embedded in the upper end of the driving seat 201 and the upper end of the moving arm 202. The moving arm 202 can be rotated on the driving seat 201 through the motor 205, and the connecting arm 203 can be rotated at the end of the moving arm 202.

[0033] In this embodiment, the connecting arm 203 is screwed to the controller 1 through the connecting column 204. A protrusion adapted to the connecting column 204 is fixed to the rear side of the controller 1. The protrusion facilitates the connection between the controller 1 and the connecting column 204. The connecting column 204 is transmission-connected to the output end of the motor 205. The motor 205 controls the rotation of the connecting column 204, thereby driving the controller 1 connected to the connecting column 204 to rotate.

[0034] In this embodiment, the mobile base 3 is provided with motors 205 corresponding to the number of the moving wheels 301. The output end of the motor 205 is transmission-connected with the moving wheels 301. The moving wheels 301 are driven by the motor 205, thereby controlling the overall position movement.

[0035] In this embodiment, the input end of the single-chip microcomputer 4 is communicatively connected with the output end of the monitoring sensor 103 and the timer 5, the output end of the single-chip microcomputer 4 is communicatively connected with the input end of the motor 205, the single-chip microcomputer 4 and the terminal 7 are wirelessly connected via the wireless connector 6, a timing signal is sent to the single-chip microcomputer 4 via the timer 5, the single-chip microcomputer 4 controls the motor 205 at the moving wheel 301 to be enabled, the single-chip microcomputer 4 receives the data monitored by the monitoring sensor 103, and sends it to the terminal 7 via the wireless connector 6, and the terminal 7 sends a control signal to the single-chip microcomputer 4 or the timer 5 via the wireless connector 6.

[0036] Specifically, the controller 1 displays the monitoring data through the display screen 101 on the front side, controls the activation of the controller 1 and the monitoring sensor 103 through the control button 102, and monitors the concentration of methane, the concentration of hydrogen sulfide, the wind speed and other data in the tunnel through the monitoring sensor 103;

[0038] Considering the long length of the tunnel, if monitoring is carried out through one control device, it will take too long and the data will lag. Therefore, according to the length of the tunnel and the endurance of the mobile base 3, multiple control devices are set in the tunnel. The control devices move on the roads on both sides of the tunnel without affecting the traffic in the tunnel. According to the monitoring length of the monitoring and control device, the timing signal time of the timer 5 is set, and the timing signal is sent to the single-chip microcomputer 4 through the timer 5. The single-chip microcomputer 4 controls the driving direction of the motor 205 at the moving wheel 301 from forward to reverse, thereby controlling the moving wheel 301 to move forward and backward, and realizes the monitoring of the fixed interval of the monitoring and control device. The single-chip microcomputer 4 receives the data monitored by the monitoring sensor 103 and sends it to the terminal 7 through the wireless connector 6.
