In order to ensure traffic scene safety, operation management and public security prevention, corresponding monitoring equipment is often used.
[0003] The utility model with the existing authorization announcement number CN220623328U discloses a comprehensive monitoring device for rail transit. By utilizing the horizontal, left and right, and up and down rotation transmission characteristics of the calibration and adjustment mechanism, the monitoring position of the monitoring probe can be adjusted to any position. On the one hand, it can better adapt to the flexible and changeable monitoring environment of rail transit, and on the other hand, it can improve the multi-directional monitoring and monitor the environment of rail transit in all directions more clearly.

DETAILED DESCRIPTION
[0023] See also Figure 1-5 A monitoring device for rail transit includes a control body 1, a panoramic camera 2 is fixedly connected to the bottom surface of the control body 1, a fire warning mechanism 3 is arranged above the control body 1, and the fire warning mechanism 3 includes a bottom plate 301, and a detection tube 303, a warning light 304 and a loudspeaker alarm 305 are respectively fixedly connected to the upper surface of the bottom plate 301, a connecting block 4 is fixedly connected to the back of the control body 1, and a plurality of identical air outlet holes 5 are opened on the outer surface of the detection tube 303. By providing the connecting block 4, the control body 1 can be extended to other structures that are convenient for installing the entire monitoring device. By providing the air outlet holes 5, a spatial structure that is convenient for airflow flow can be provided at the bottom end of the detection tube 303, thereby ensuring the smooth operation of the fire warning mechanism 3.
[0024] The inner wall of the base plate 301 and the inner wall of the control body 1 are threadedly connected with two groups of fastening bolts 302. The back of the connecting block 4 is fixedly connected with a mounting plate 6. The front of the mounting plate 6 is provided with a number of identical mounting holes 7. By providing the mounting holes 7, the mounting plate 6 can be connected and installed with the mounting structure of the rail transit that needs to be monitored in cooperation with external bolts and other structures, thereby facilitating the installation of the entire monitoring equipment.
[0025] The inner wall of the detection cylinder 303 is fixedly connected with a bracket 306 and an exhaust fan 308 respectively. The outer surface of each set of fastening bolts 302 is sleeved with two washers 8. The bottom surface of each washer 8 is in contact with the upper surface of the base plate 301. By providing washers 8, they can be padded between the base plate 301 and the fastening bolts 302, thereby increasing the contact area between the two and increasing the fastening effect of the fastening bolts 302.
[0026] The inner wall of the bracket 306 is fixedly connected to the smoke sensor 307, the inner wall of the detection tube 303 is threadedly connected to the protective shell 9, and the inner wall of the protective shell 9 is fixedly connected to the dustproof net 10. By providing the protective shell 9, the dustproof net 10 can be shaped and supported and threadedly connected to the detection tube 303, thereby filtering a part of the flying dust drawn into the top of the detection tube 303 by the exhaust fan 308 and allowing possible fire smoke to pass through, thereby facilitating the detection of smoke by the smoke sensor 307, thereby maximizing the cleanliness of the smoke sensor 307 and the exhaust fan 308.
[0027] The warning light 304, the loudspeaker alarm 305, the smoke sensor 307 and the exhaust fan 308 are all electrically connected to the control body 1 through wires.

[0028] The working principle of the utility model is: when in use, the mounting plate 6 is fixed to the mounting structure of the area with good ventilation and requiring key monitoring by using the fixing structure such as the external bolts in conjunction with the mounting holes 7, and then the control body 1 is connected to the remote monitoring system, the control body 1 will control the exhaust fan 308 to be powered on for periodic exhaust, and the air outside the detection tube 303 is drawn into the detection tube 303 through the top of the detection tube 303, and at the same time the dustproof net 10 can block the flying dust in the air to a certain extent, and when a fire occurs near the monitoring device and a certain amount of smoke is generated, the fire smoke can pass through the dustproof net 10 and the exhaust fan 308 and then blow to the smoke sensor 307, and the smoke sensor 307 also performs periodic detection, and the smoke sensor When 307 detects that the fire smoke reaches a certain level or becomes thicker and thicker, the control body 1 receives and processes the fire smoke signal, and the control body 1 can control the warning light 304 to flash and control the loudspeaker alarm 305 to sound an alarm, thereby attracting the attention and vigilance of on-site patrol or staff. At the same time, the control body 1 alarms the remote monitoring system, thereby attracting the attention of the remote monitoring security personnel, so as to discover the fire in time and handle it quickly and conveniently. The design of the entire rail transit monitoring equipment effectively solves the problem that the fire warning structure lacks smoke detection and alarm, resulting in the inability to detect fire smoke in time when used in rail transit spaces with good ventilation, resulting in fewer monitoring functions and more limited application scenarios.
