Description

Technical Field

[0001] The utility model relates to the field of wire trough water accumulation monitoring, in particular to a wire trough water accumulation monitoring and alarm device for an AFC system of a subway. Background Art

[0002] The AFC system is an important automated ticketing system for rail transit, which can realize functions such as ticketing, ticket checking, billing, charging, statistics, etc., and improve passenger service efficiency. The AFC system station equipment includes a variety of equipment such as automatic ticket vending machines, automatic ticket checking machines, semi-automatic ticket vending machines, automatic ticket checking machines, and monitoring workstations, and the power and communication connections between these devices need to be realized through AFC cable ducts. AFC cable ducts are usually used to lay AFC power cables and network cables.

[0003] Usually, AFC cable ducts are installed underground, that is, they are buried in the cushion layer of marble floor tiles on the ground floor of the underground station hall, close to the middle plate structure surface. The marble floor tiles on the ground floor of the station hall are constructed by dry pasting. The main material of this dry pasting method is dry hard cement mortar, which is loose inside and has high water permeability. Once external water source penetrates into the cushion layer of floor tile mortar, it will seep into the cushion layer. After the cushion layer is saturated with water, it will penetrate into the buried AFC cable duct, which is easy to cause water accumulation in the cable duct. If the AFC cable duct accumulates water for a long time, it is easy to cause short circuit and equipment corrosion, reduce the service life, and even cause AFC equipment failure in severe cases, directly affecting operation services.

[0004] However, the structure of rail transit stations is relatively complex, and most areas have been blocked by decorative materials after operation. It is difficult to deal with water accumulation in AFC cable ducts by checking for leakage points. Usually, manual pumping is used to temporarily deal with the water accumulation in the cable ducts. However, there are a large number of AFC cable ducts, and the manual method is time-consuming and labor-intensive, increasing operating and maintenance costs, and failing to effectively solve the problem.

[0005] Moreover, manual inspection of water accumulation in cable troughs can only reveal water accumulation near the cable trough covers, but cannot observe water accumulation in the middle of the cable trough between the cable trough covers. If there is water accumulation in the middle of the cable trough, it is difficult to detect it manually, posing certain safety hazards. Utility Model Content

[0006] In order to solve the problem that temporary treatment of water accumulation in the cable trough by manual periodic pumping is time-consuming and labor-intensive, increases operation and maintenance costs, cannot effectively solve the problem of water accumulation in the cable trough, and cannot observe the water accumulation in the middle of the cable trough between the cable trough covers by manual method, and there is a safety hazard, the utility model provides a subway AFC system cable trough water accumulation monitoring and alarm device, the device includes a signal transmitting module and a signal receiving module, the signal transmitting module is data-connected with the signal receiving module, the signal transmitting module includes a water immersion sensor and a transmitter, the transmitter includes a first power supply, the water immersion sensor is connected to the transmitter, the water immersion sensor is placed between two adjacent AFC cable trough covers, and the transmitter is placed in the AFC cable trough.

[0007] Principle of the utility model: The water immersion sensor is installed between two adjacent AFC wire duct covers under the floor of the subway station hall. It can not only monitor the water accumulation in the AFC wire duct, but also monitor the water accumulation in the middle of the wire duct between the wire duct covers. It can monitor in a more comprehensive way to reduce safety hazards. The water accumulation in the AFC wire duct is monitored by the sensor probe of the water immersion sensor. If the water accumulation reaches a certain depth, the sensor probe will short-circuit when encountering water, and the first power supply loop of the transmitter will be closed to supply power to the transmitter. The transmitter will be powered on to transmit a signal, and the signal first transmission module of the signal receiving module will receive the signal and transmit the signal to the signal second transmission module. The signal second transmission module will transmit the signal to the monitoring system, and the corresponding alarm information will be displayed on the display interface of the monitoring workstation to remind the staff in the subway. The subway staff will arrange AFC professional and technical personnel to go to the corresponding point wire duct for drainage and other treatments. There is no need to pump water regularly, which reduces the waste of time and labor resources, reduces the operation and maintenance costs, and can effectively solve the water accumulation problem in the AFC wire duct.

[0008] Further, the water immersion sensor comprises a sensor probe, and the sensor probe is located on the top of the water immersion sensor.

[0009] In order to prevent the sensor probe from short-circuiting when encountering water in the first place, the utility model adds a fixing cover to fix the position of the sensor probe, reduce the movement or deviation of the sensor probe, and protect the sensor probe at the same time.

[0010] Furthermore, the water immersion sensor also includes a fixed cover, and the sensor probe is built in the fixed cover.

[0011] In order to prevent the sensor probe from short-circuiting when encountering water in the first place, the utility model sets a notch on the bottom of the fixed cover, which is conducive to the accumulated water flowing into the fixed cover and making the sensor probe contact with the water surface, thereby realizing the sensor probe short-circuiting when encountering water and triggering corresponding alarm information. At the same time, in order to reduce the buoyancy generated by the contact between the accumulated water and the fixed cover, the fixed cover floats on the surface of the accumulated water, resulting in the problem that the sensor probe cannot contact the accumulated water, the utility model adds a gravity device on the top of the fixed cover.

[0012] Furthermore, a notch is provided at the bottom of the fixed cover.

[0013] Furthermore, a gravity device for fixing the fixed cover is provided on the top of the fixed cover.

[0014] In order to reduce the potential safety hazard caused by the contact between the signal transmitting module and the accumulated water and ensure that the signal transmitting module can work normally when water accumulates in the wire slot, the utility model adopts a waterproof connector to connect the water immersion sensor and the transmitter. In order to fix and lock the connecting wires between the water immersion sensor and the transmitter and reduce the problem that the circuit cannot be closed due to poor connection or connection falling off, resulting in the transmitter being unable to transmit signals, the waterproof connector includes a loose nut, a waterproof foot pad, a clamping claw, a waterproof rubber ring and a tightening cap.

[0015] Furthermore, the water immersion sensor and the transmitter are connected by a waterproof connector.

[0016] Furthermore, the waterproof joint includes a locking nut, a waterproof foot pad, a clamping claw, a waterproof rubber ring and a locking cap, one end of the locking nut is connected to the transmitter, the other end of the locking nut is connected to one end of the waterproof foot pad, one end of the waterproof foot pad is connected to one end of the clamping claw, the other end of the clamping claw is connected to one end of the waterproof rubber ring, the other end of the waterproof rubber ring is connected to one end of the locking cap, and the other end of the locking cap is connected to the water immersion sensor.

[0017] Furthermore, the device also includes a waterproof box, and the transmitter is built in the waterproof box.

[0018] Further, the signal receiving module includes a second power supply, a first signal transmission module and a second signal transmission module, and the first signal transmission module is data-connected with the second signal transmission module.

[0019] Furthermore, the first signal transmission module is connected to the transmitter data, and the second signal transmission module is connected to the monitoring system data.

[0020] One or more technical solutions provided by the utility model have at least the following technical effects or advantages:

[0021] 1. Install the water sensor between two adjacent AFC duct covers under the floor of the subway station hall. It can not only monitor the water accumulation in the AFC duct, but also monitor the water accumulation in the middle of the duct between the duct covers, so as to conduct more comprehensive monitoring and reduce safety hazards.

[0022] 2. The water accumulation in the AFC cable duct is monitored by the sensor probe of the water immersion sensor. If the water accumulation reaches a certain depth, the sensor probe will short-circuit when encountering water, and the first power supply circuit of the transmitter will be closed to supply power to the transmitter. The transmitter will be powered on to transmit the signal, and the signal receiving module will receive the signal and transmit it to the monitoring system. The corresponding alarm information will be displayed on the display interface of the monitoring workstation. There is no need to pump out water regularly, which reduces the waste of time and labor resources, and reduces the operating and maintenance costs, which can effectively solve the problem of water accumulation in the AFC cable duct.

[0023] 3. Add a fixed cover to fix the position of the sensor probe, reduce the movement or deviation of the sensor probe, and protect the sensor probe at the same time.

[0024] 4. A notch is set at the bottom of the fixed cover to facilitate the accumulation of water to flow into the fixed cover, so that the sensor probe contacts the water surface, so that the sensor probe can short-circuit when encountering water at the first time, triggering the corresponding alarm information.

[0025] 5. Adding a gravity device on the top of the fixed cover can reduce the buoyancy caused by the contact between the accumulated water and the fixed cover. The fixed cover floats on the surface of the accumulated water, resulting in the problem that the sensor probe cannot contact the accumulated water.

[0026] 6. The water sensor and the transmitter are connected with a waterproof connector, and the transmitter is built into the waterproof box to reduce the potential safety hazard caused by the contact between the device and the accumulated water. BRIEF DESCRIPTION OF THE DRAWINGS
