[0002] With the rapid development of urban rail transit, the number of subway electromechanical equipment is constantly increasing, making the monitoring, early warning, and management of its operational status particularly important. Traditional subway electromechanical monitoring and early warning facilities generally rely on cameras combined with some environmental sensors and alarms on the subway to monitor and issue early warnings on site. However, these detection devices are prone to dust accumulation when exposed to the air, which reduces the accuracy of detection. In addition, some cameras are not used for long periods of time, and some cameras that are turned off and not in use often lack protection. The exposed and unprotected camera ends are damaged, making it impossible to take pictures when used again. Summary of the Invention

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a comprehensive monitoring and early warning device for subway electromechanical equipment, including a fixed beam 1, a support column 4 fixedly connected to the top of the fixed beam 1, a top plate 5 fixedly installed on the top of the support column 4, a side plate 3 fixedly installed on the side of the fixed beam 1 away from the controller 8, fixing screw holes 6 are provided on the corners of the side plate 3 and the top plate 5, and a monitoring camera 2 is fixedly installed on the bottom of the fixed beam 1.

[0023] This embodiment provides a comprehensive monitoring and early warning device for subway electromechanical equipment. The top of the fixed beam 1 is vertically connected to the support column 4 by welding. A top plate 5, larger than the cross-section of the fixed beam 1, is welded to the top of the support column 4. The top plate 5 has M8 fixing screw holes 6 at its four corners, forming an inverted L-shaped hoisting structure. Side-mounted plates 3 are bolted to the side of the fixed beam 1. The side-mounted plates 3 have four rectangularly distributed M6 fixing screw holes, enabling wall-mounting. The two installation methods are achieved through a detachable connection, allowing the installation mode to be selected according to site conditions.

[0024] In this embodiment, the device can be hoisted on the top via the top plate 5, or it can be fixed to the side wall via the side mounting plate 3. The monitoring camera 2 can monitor and record the subway site. The smoke alarm 7 can detect the smoke level in the environment and will sound an alarm when the smoke level is high. The temperature and humidity sensors 16 of the first detection mechanism 9 and the second detection mechanism 10 can detect the temperature and humidity of the environment.

[0025] The surveillance camera 2 is equipped with a protective mechanism 12 on its outer side. The protective mechanism 12 includes an outer protective frame 21, an inner protective frame 22, and several buffer springs 23 disposed between the outer protective frame 21 and the inner protective frame 22. Electric telescopic rods 11 are installed on both sides of the bottom end of the fixed beam 1 near the surveillance camera 2. A first detection mechanism 9 is installed on one side of the bottom of the fixed beam 1, and a second detection mechanism 10 is installed on the other side of the bottom of the fixed beam 1. Both the first detection mechanism 9 and the second detection mechanism 10 include a mounting base 14, a mounting groove 15 opened at the bottom of the mounting base 14, and a temperature and humidity sensor 16 installed inside the mounting groove 15. A micro motor 17 is installed on one side of the mounting base 14. The output end of the micro motor 17 is connected to a rotating shaft 18. A base plate 19 is connected to the bottom of the rotating shaft 18. A soft brush 20 is provided on one side of the top of the base plate 19. A side frame 24 is connected to the top of one side of the mounting base 14. A pressing plate 25 is connected to the bottom of the side frame 24. An early warning buzzer 13 is installed on one side of the front of the fixed beam 1. A smoke alarm 7 is installed on the other side of the front of the fixed beam 1. A controller 8 is installed in the middle of one side of the fixed beam 1. The controller 8 is model GCAN-PLC-400. The temperature and humidity sensor 16 is model HM40.

[0026] Specifically, the surveillance camera 2 is fixed to the center of the bottom of the fixed beam 1 via a flange, with its lens facing downwards. The protective mechanism 12 adopts a double-layer sleeve structure: the outer protective frame 21 is a 304 stainless steel cylinder (Φ120×150mm), and the inner protective frame 22 is an ABS engineering plastic cylinder (Φ100×130mm). The two are elastically connected by eight sets of stainless steel buffer springs 23 (wire diameter 2mm, free length 30mm) distributed in a ring array. The inner wall of the inner protective frame 22 is bonded with a 2mm thick silicone rubber anti-scratch layer (Shore hardness 50A). Two sets of electric telescopic rods 11 (stroke 0-200mm, built-in potentiometer displacement sensor) are symmetrically installed on both sides of the surveillance camera 2, and their output rods are rigidly connected to the top flange of the outer protective frame 21.

[0027] The testing mechanism comprises a symmetrically arranged first testing mechanism 9 and a second testing mechanism 10. The mounting base 14 is an aluminum alloy casting with a Φ25mm through-hole mounting groove 15 at its bottom. The temperature and humidity sensor 16 (HM40 type) is vertically fixed in the groove via a threaded sealing ring, with the detection end extending 20mm below the mounting groove 15. A micro motor 17 (24V DC geared motor) is fixed to the side of the mounting base 14 via a bracket, and its output shaft is connected to a Φ8mm rotating shaft 18 via a coupling. The axis of the rotating shaft 18 is 15mm off-center from the axis of the temperature and humidity sensor 16, and a stainless steel base plate 19 (Φ50×2mm) is welded to its bottom. A nylon soft brush 20 (brush length 20mm) is welded to the edge of the base plate 19, with the brush tip maintaining a 2mm interference contact with the surface of the temperature and humidity sensor's detection end. The side frame 24 is an L-shaped steel bracket, with an arc-shaped rubber extrusion plate 25 (radius 30mm, thickness 5mm, Shore A hardness 70A) bolted to its bottom, forming tangential contact with the rotation trajectory of the soft brush 20.

[0028] See Figure 1-4 The temperature and humidity sensor 16, the micro motor 17, the early warning buzzer 13, the smoke alarm 7, and the electric telescopic rod 11 are all electrically connected to an external control terminal through the controller 8. The outer protective frame 21 and the inner protective frame 22 are connected through a buffer spring 23. The output end of the electric telescopic rod 11 is connected to the top of the outer protective frame 21.

[0029] The controller 8 (GCAN-PLC-400 type) integrates a CAN bus interface and connects to each actuator via shielded twisted-pair cables. Specifically, it receives 4-20mA analog signal input from the temperature and humidity sensor 16; outputs PWM signals to control the speed of the micro motor 17 (0-30rpm adjustable); controls the warning buzzer 13 (120dB) and the smoke alarm 7 (photoelectric type) via relays; and sends RS485 commands to control the travel of the electric telescopic mast 11 (accuracy ±1mm). The controller's built-in logic program implements the following: when the temperature > 50℃ or humidity > 90%RH, it activates the warning buzzer and sends an alarm signal; when the smoke concentration > 5%obs / m³, it activates the smoke alarm; and it receives camera start / stop commands from the train dispatching system, controlling the electric telescopic mast 11 to descend 200mm within 8 seconds to protect the camera lens when the camera is turned off.

[0030] In this embodiment, when the monitoring camera 2 is turned off and not in use, the electric telescopic rod 11 can be activated to lower the protective mechanism 12, so that the protective mechanism 12 is fitted onto the detection end position of the monitoring camera 2, and the camera end of the monitoring camera 2 is protected by the outer protective frame 21 and the inner protective frame 22.

[0031] See Figure 1-4The soft brush 20 contacts the detection end at the bottom of the temperature and humidity sensor 16, the extrusion plate 25 corresponds to the soft brush 20, the top of the mounting base 14 is fixedly connected to the surface at the bottom of the fixed beam 1, and the bottom of the temperature and humidity sensor 16 extends through the mounting groove 15 to the outside of the mounting base 14.

[0032] In this embodiment, when the temperature or humidity is abnormal, the controller 8 controls the warning buzzer 13 to sound an alarm. During the use of the entire device, the detection end of the temperature and humidity sensor 16 will be exposed to the outside and continuously accumulate dust. The micro motor 17 can be started to drive the rotating shaft 18 and the base plate 19 to rotate. When the soft brush 20 on the top of the base plate 19 rotates to the bottom of the temperature and humidity sensor 16, the soft brush 20 can clean the detection end of the temperature and humidity sensor 16. When the base plate 19 rotates to the other side, the soft brush 20 will be squeezed and contacted by the squeezing plate 25, so that the dust on the squeezed soft brush 20 will be popped off, cleaning away the large pieces of accumulated dust on the surface.

[0033] In practical use, this utility model, a comprehensive monitoring and early warning device for subway electromechanical equipment, can be suspended from the top via the top plate 5 or fixed to the side wall via the side mounting plate 3. The monitoring camera 2 can record video of the subway site, the smoke alarm 7 can detect the smoke level in the environment and trigger an alarm when the smoke level is high, and the temperature and humidity sensors 16 of the first detection mechanism 9 and the second detection mechanism 10 can detect the temperature and humidity of the environment. When the temperature or humidity is abnormal, the controller 8 controls the early warning buzzer 13 to sound an alarm. During the entire operation of the device, the detection end of the temperature and humidity sensor 16 will... Exposed to the outside, dust accumulates continuously. The micro motor 17 can be activated to drive the rotating shaft 18 and the film 19 to rotate. When the soft brush 20 on the top of the film 19 rotates to below the temperature and humidity sensor 16, the soft brush 20 can clean the detection end at the bottom of the temperature and humidity sensor 16, reducing the phenomenon of inaccurate detection and reduced accuracy caused by dust accumulation. In addition, when the monitoring camera 2 is turned off and not in use, the electric telescopic rod 11 can be activated to lower the protective mechanism 12, so that the protective mechanism 12 is fitted at the detection end of the monitoring camera 2. The outer protective frame 21 and the inner protective frame 22 protect the camera end of the monitoring camera 2, providing good protection and reducing the risk of damage to the monitoring camera 2 when it is not in operation.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
