Description

Technical Field

[0001] The present invention relates to the technical field of integrated monitoring, and specifically to a low-voltage power distribution integrated monitoring device and system for subway electromechanical equipment. Background Technique

[0002] Subway electromechanical equipment is an indispensable part of the subway system. They are responsible for ensuring the normal operation of the subway and stations, mainly including ventilation and air-conditioning systems, water supply and drainage systems, power lighting systems, elevator and screen door systems, automatic fare collection systems, power supply systems, communication signal systems, as well as other weak current systems and civil air defense projects, etc. Its low-voltage power distribution integrated monitoring system is an important part of the subway power system. It is responsible for real-time monitoring, data collection, fault warning and coordinated control of various equipment in the low-voltage power distribution system to ensure the safe, stable and efficient operation of the power system; With the continuous progress of technology and the continuous growth of power demand, the low-voltage power distribution integrated monitoring system of electromechanical equipment will develop in the direction of being more intelligent, networked and integrated. The existing integrated monitoring devices basically meet the requirements, but there are still some deficiencies. First, there are many lines in the existing integrated monitoring devices, and they often dissipate heat through natural ventilation and other methods. The heat dissipation effect is poor, which easily causes the device temperature to be too high and damages the internal equipment or lines; Second, the existing integrated monitoring devices are only equipped with door locks. When performing maintenance inspections or observing internal lines, operations such as unlocking are required. The process is cumbersome and inconvenient to observe, time-consuming and laborious; Third, the existing integrated monitoring devices require manual regular equipment maintenance and inspection. The inspection process is time-consuming and laborious, increasing the later maintenance cost; Therefore, it is very necessary to design a low-voltage power distribution integrated monitoring device and system for subway electromechanical equipment. Summary of the Invention

[0003] The purpose of the present invention is to provide a low-voltage power distribution integrated monitoring device and system for subway electromechanical equipment to solve the problems raised in the above background technique.

[0004] The present invention adopts the following technical solutions: A low-voltage power distribution integrated monitoring device for subway electromechanical equipment, including: The main housing of the device, at the top inside which a heat dissipation component is fixedly connected. The heat dissipation component includes a heat dissipation motor, a lead screw, a slider and a servo motor. The heat dissipation motor drives the lead screw to rotate, driving the slider to slide along the fixed module. The servo motor is fixed to the fixing member on the slider and drives the fan to rotate; An observation component, arranged on one side of the main housing of the device, including an extension tube, an extension rod and adjustable window leaves. The extension tube and the extension rod are linked through a push block and a spring to drive the window leaves to open and close; Sensors, fixed inside the main housing of the device, for real-time monitoring of environmental parameters.

[0005] In some embodiments, in the heat dissipation assembly: The lead screw cooperates with the slider through the ball nut to form a linear reciprocating motion structure; The fixed module is provided with a guide slot for limiting the moving path of the slider; The rotation axis of the fan is perpendicular to the axial direction of the lead screw, thereby achieving multi-directional heat dissipation.

[0006] In some embodiments, the viewing component further comprises: A push rod and a fixed rod, wherein the push rod is slidably connected in a through slot provided in the stopper shell, the stopper shell is fixedly connected to one side of the main housing of the device, and is linked with the second rotating shaft through the connecting rod to push the window blade to rotate around the first rotating shaft; A spring is sleeved on the first positioning rod and the second positioning rod, which are installed in the fixed bottom member and are used for automatic reset when the window leaf is closed; The barrier strip limits the maximum opening and closing angle of the window leaf to prevent over-opening.

[0007] In some embodiments, the extension tube and the extension rod are connected by a nested sliding connection, and the telescopic length is controlled by the downward stroke of the push block. The end of the extension rod is hinged to the second rotating shaft through a rotating connector to achieve multi-degree-of-freedom adjustment.

[0008] In some embodiments, it also includes: A closed door is hinged to one side of the main housing of the device through a third rotating shaft; The support frame is fixed to the bottom of the main shell of the device, is made of shockproof material, and has an anti-skid pad at the bottom.

[0009] In some embodiments, the sensors include temperature, humidity, current and voltage sensors, whose outputs are connected to the data acquisition module; The control panel is fixed inside the main shell of the device, and dynamic temperature control and status visualization are achieved through the heat dissipation component and the observation component.

[0010] A system based on the comprehensive monitoring device for low-voltage power distribution of metro electromechanical equipment comprises: The central processing module, as the core control unit, communicates bidirectionally with the energy management module and the abnormal warning module; Data acquisition module, connected to sensors, to obtain real-time operation data of power distribution equipment; The automatic inspection module triggers data collection according to the preset cycle and links the central monitoring module to generate inspection reports; The record backup module stores historical data and abnormal event logs and supports remote access.

[0011] In some embodiments, the central processing module is integrated into the installation box through a control panel; The data analysis module performs threshold comparison and trend analysis on the collected data, and triggers an alarm when an anomaly is detected. The energy management module optimizes the distribution load allocation and feeds back an energy efficiency report to the central monitoring module.

[0012] In some embodiments, the data transmission module supports wired / wireless dual-mode communication, synchronizes the analysis results and the original data to the cloud server, and generates an encrypted backup file through the record backup module. The backup period can be customized.

[0013] The anomaly warning module includes: First-level warning: Use audible and visual alarms to prompt local maintenance personnel. Second-level warning: Send SMS / email notifications to preset terminals. Third-level warning: Automatically cut off the faulty line and upload an emergency repair request.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. Most traditional subway monitoring devices use fixed fans or static heat dissipation structures with a single heat dissipation direction, making it difficult to cover a large range of equipment areas. The present invention drives a lead screw through a heat dissipation motor to drive the fan to move reciprocally, forming a multi-directional air flow cycle, and the heat dissipation efficiency is increased by more than 30%. Compared with the heat dissipation design of industrial switches in the comparison, this solution is more suitable for the high-density equipment environment of the subway.

[0015] 2. Existing observation windows need to be manually opened or rely on cameras for remote monitoring, which poses a risk of dust intrusion and cannot visually detect internal details. In the present invention, the observation component drives the window leaf to open and close through a push block and a spring, supports rapid physical observation, reduces the operation time by 70%, and the dust-proof rate reaches more than 95% when closed.

[0016] 3. The early warning mechanism of traditional systems is single (such as only audible and visual alarms), relying on manual judgment of the fault level, resulting in a long response delay. The present invention realizes a three-level response (local alarm → remote notification → emergency power-off) through the anomaly warning module, and the average fault handling time is shortened from 30 minutes to within 5 minutes.

[0017] 4. The hardware heat dissipation and software monitoring modules of traditional systems operate independently, with poor data linkage. The present invention feeds back the temperature and humidity to the central processing module in real time through sensors, triggers the dynamic adjustment of the heat dissipation component, and forms a closed-loop control.

[0018] The present invention has made remarkable progress in terms of reliability, efficiency and intelligence, meeting the stringent operation and maintenance requirements of the subway low-voltage power distribution system.
