Description

Technical Field

[0001] This application relates to the field of equipment condition monitoring, and in particular to a leaky cable clamp condition monitoring device. Background Technology

[0002] With the development of modern electronic technology, advanced communication technology, and digital sensor technology, the monitoring of the operating status of leaky cable tunnels has received widespread attention. Leaky cables play a crucial role in railway communication networks, and their operational stability directly affects the safety and smooth operation of railway communications. Effective monitoring of the leaky cable's operating status helps to promptly identify potential problems, ensure the normal operation of the railway communication system, and reduce losses and impacts caused by malfunctions. Simultaneously, the stability of the leaky cable clamps, as a vital component for securing the leaky cable, is also crucial for its proper use.

[0003] In monitoring the operational status of leaky cable tunnels, traditional leaky cable fault detection mainly relies on manual inspection. However, due to limitations such as long tunnels, limited inspection windows, and passive inspection methods, some faults are difficult to detect in a timely manner. The detection of leaky cable clamp status also primarily relies on manual inspection. However, shock waves generated by high-speed vehicles and corrosive environments caused by humidity and freeze-thaw cycles can easily affect the performance of the clamps, leading to their breakage. Manual inspection is inefficient and struggles to meet practical needs. Furthermore, when there are numerous clamp status acquisition units, directly uploading information to the main control unit would result in too many management substations, potentially causing congestion. Additionally, data transmission is also challenging due to tunnel curvature and transmission distance limitations.

[0004] These conventional methods in existing technologies have significant drawbacks. Manual inspections are difficult to implement in real time, leading to the failure to detect cable leaks and clamp status issues in a timely manner. This could result in serious situations such as cable detachment, threatening the safe operation of locomotives. Moreover, the direct uploading of information from numerous clamp status acquisition units to the main control unit can easily cause congestion, affecting the normal processing and transmission of data, and consequently impacting the effective monitoring of the operating status of cable-leaking tunnels. Summary of the Invention

[0005] To overcome the above-mentioned technical problems, this application provides a leaky cable clamp status monitoring device.

[0006] The leaky cable clamp status monitoring device provided in this application adopts the following technical solution: A leaky cable clamp status monitoring device, installed at the leaky cable clamp, includes: a temperature sensor, a switch quantity acquisition unit, an attitude sensor, a clamp status acquisition unit, a data central forwarding unit, and a main control unit. The temperature sensor detects the ambient temperature of the leaky cable clamp; the switch quantity acquisition unit detects the contact state of the clamp's latch; the attitude sensor detects the tilt angle of the clamp; the clamp status acquisition unit is signal-connected to the temperature sensor, the switch quantity acquisition unit, and the attitude sensor; the clamp status acquisition unit transmits data from the temperature sensor, the switch quantity acquisition unit, and the attitude sensor to the data central forwarding unit via a wireless transmission module; the data central forwarding unit transmits the data to the main control unit via Ethernet for analysis and processing.

[0007] By adopting the above technical solution, the ambient temperature, latch contact status, and tilt angle of the leaky cable clamp can be monitored in real time. The relevant data is wirelessly transmitted to the data central forwarding unit through the clamp status acquisition unit, and then transmitted to the main control unit via Ethernet for analysis and processing. This enables online monitoring of the leaky cable clamp status, timely detection of problems such as loosening or falling off the clamp, ensuring the stable operation of the leaky cable, and thus ensuring the safety of the railway communication network.

[0008] Optionally, the wireless transmission module adopts a low-power wireless communication module, which supports sleep mode and wakes up when an interrupt signal is received.

[0009] By adopting the above technical solution, the power consumption of the chuck status acquisition unit can be reduced by using a low-power wireless communication module, and its support for sleep mode can further save power consumption. When the interrupt signal is received, it can be woken up to ensure timely transmission of the status data of the leaky cable chuck. Combined with other parts of the leaky cable chuck status monitoring device, effective monitoring of the status of the leaky cable chuck can be achieved.

[0010] Optionally, the temperature sensor is a bimetallic strip temperature sensor, which includes a temperature sensing element, a connecting element, and a first protective sleeve. The temperature sensing element is formed by stacking two metal strips with different coefficients of thermal expansion. The connecting element and the temperature sensing element are both sealed inside the first protective sleeve. One end of the temperature sensing element is a first temperature sensing lead fixedly connected to one end of the first protective sleeve, and one end of the connecting element is a second temperature sensing lead fixedly connected to the other end of the first protective sleeve. The end of the temperature sensing element away from the first temperature sensing lead is provided with a moving temperature sensing contact, and the end of the connecting element away from the second temperature sensing lead is provided with a stationary temperature sensing contact. The first temperature sensing lead and the second temperature sensing lead are connected to the input port of the fixture status acquisition unit via wires.

[0011] By adopting the above technical solution, the bimetallic strip temperature sensor can detect the ambient temperature of the leaky cable clamp, and its sensing element and connecting element are sealed within the first protective sleeve, ensuring the stability and accuracy of the detection. Furthermore, this temperature sensor achieves temperature detection solely through its mechanical structure, requiring no power supply, thus offering energy-saving advantages.

[0012] Optionally, the switch quantity acquisition unit includes a latching stationary contact and a latching moving contact. The latching stationary contact is fixed to the locking seat of the latch of the leaky cable clamp, and the latching moving contact is fixed to the locking tongue of the latch of the leaky cable clamp. The latching stationary contact and the latching moving contact are connected to the input port of the clamp status acquisition unit through wires.

[0013] By adopting the above technical solution, the switch quantity acquisition unit uses the latching stationary contact and the latching moving contact to be fixed to the locking seat and locking tongue of the leaky cable clamp lock, respectively, and is connected to the input port of the clamp status acquisition unit, which can accurately detect the contact status of the leaky cable clamp lock. When the clamp lock is normally locked, the latching stationary contact and the latching moving contact are in contact, so that the corresponding interface of the clamp status acquisition unit is connected; once the clamp lock becomes loose or falls off, the latching stationary contact and the latching moving contact separate, and the corresponding interface of the clamp status acquisition unit is interrupted, realizing efficient monitoring of the working status of the leaky cable clamp lock, timely detection of clamp abnormalities, and ensuring stable fixing of the leaky cable and safe operation of the railway communication network.

[0014] Optionally, the attitude sensor is a ball tilt switch, which includes a rolling seat, a conductive shell outside the rolling seat, an insulating sleeve between the rolling seat and the conductive shell, a conductive ball in the space between the rolling seat and the conductive shell, and a second protective sleeve covering the rolling seat and the conductive shell. The rolling seat has a groove for positioning the ball, a first attitude lead end at the rolling seat, and a second attitude lead end at the conductive shell. The first attitude lead end and the second attitude lead end are connected to the input port of the fixture status acquisition unit via wires.

[0015] By adopting the above technical solution, this attitude sensor uses a ball tilt switch, which has a simple and reliable structure. It detects changes in the clamp's attitude by the rolling of conductive balls within the rolling seat, accurately and promptly reflecting any abnormalities in the clamp's tilt angle. Furthermore, the ball tilt switch has a protective structure; the rolling seat and conductive shell are encased in protective sleeves, and an insulating sleeve is placed between the rolling seat and the conductive shell, effectively preventing interference from external factors and ensuring the stability and accuracy of the detection signal. In addition, this attitude sensor achieves attitude detection solely through its mechanical structure, requiring no additional power supply, thus reducing energy consumption and cost, and improving the reliability and economy of the entire monitoring device.

[0016] Optionally, the data central forwarding unit is configured with multiple wireless receiving interfaces and multiple Ethernet output interfaces. The multiple wireless receiving interfaces are respectively connected to the card status acquisition unit, and the multiple Ethernet output interfaces are respectively connected to the main control unit.

[0017] By adopting the above technical solution, the data centralized forwarding unit can receive data by connecting to the card status acquisition unit through n wireless receiving interfaces, and then transmit the data to the main control unit by connecting to the main control unit through m Ethernet output interfaces. This solves the problems of blockage caused by the large number and high density of card status acquisition units, which can lead to too many management substations in the main control unit when directly uploading information to the main control unit. It also solves the problem of LORA transmission distance being limited by tunnel curvature and acquisition unit installation height, thus realizing hierarchical data transmission.

[0018] Optionally, it also includes a power supply module, which includes a battery and supplies power to the fixture status acquisition unit through an energy management circuit.

[0019] By adopting the above technical solution, power can be provided to the fixture status acquisition unit to ensure its normal operation, and the data acquisition and transmission of the temperature sensor, switch quantity acquisition unit and attitude sensor can be carried out smoothly.

[0020] Optionally, it also includes an energy harvesting module, which includes a solar panel and a wind power generation device, and the energy harvesting module charges the power supply module through the energy management circuit.

[0021] By adopting the above technical solution and setting up an energy harvesting module, solar panels and wind power generation devices can be used to convert solar and wind power into electrical energy, and the power supply module can be charged through the energy management circuit, reducing dependence on external power sources, improving the autonomy and sustainability of the device's power supply, and ensuring that the leaky cable clamp status monitoring device can work continuously and stably.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. Real-time monitoring of the status of leaky cable clamps, timely detection of problems such as loosening, detachment, and changes in posture of leaky cable clamps, to prevent leaky cables from falling off and threatening the safe operation of locomotives; 2. A hierarchical transmission method is adopted, in which multiple card status acquisition units are connected by a centralized data forwarding unit and the data is transmitted to the main control unit via Ethernet. This solves the problem of too many management substations and easy congestion caused by a large number of card status acquisition units directly uploading information. 3. The wireless transmission module adopts a low-power design and supports sleep mode, making it suitable for working environments where the card module is powered by a separate battery, thus saving power consumption.

Detailed Implementation

[0025] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0026] This application discloses a leaky cable clamp status monitoring device.

[0027] like Figure 1 and Figure 2As shown, the leaky cable clamp status monitoring device includes a temperature sensor 2, a switch quantity acquisition unit, an attitude sensor 3, a clamp status acquisition unit, a data centralization and forwarding unit, and a main control unit. The temperature sensor 2, switch quantity acquisition unit, and attitude sensor 3 detect the ambient temperature, latch contact status, and tilt angle of the leaky cable clamp 1, respectively. The detection data is transmitted to the data centralization and forwarding unit via the wireless transmission module of the clamp status acquisition unit. The data centralization and forwarding unit then transmits the data to the main control unit via Ethernet for analysis and processing, achieving real-time and comprehensive monitoring of the leaky cable clamp 1's status. The clamp status acquisition unit is an MCU main control unit, which can be a 51 series microcontroller. This microcontroller has 3KB of SRAM and 32KB of flash memory, meeting software design requirements. It has two serial ports, one for software debugging and the other for communication with the wireless transmission module. The remaining 23 GPIOs can be used to connect other devices, such as the temperature sensor 2, switch quantity acquisition unit, and attitude sensor 3. It also has a built-in clock and reset, simplifying the external circuit design and greatly reducing the risk of device downtime due to external component failures. The wireless transmission module includes a LORA module and a LORA antenna 4. The LORA module can be a WH-101-H20 model module, which supports sleep mode and wakes up when receiving an interrupt signal. The transmission distance of the wireless transmission module can reach 5.5km in open and interference-free conditions. The LORA module is connected to the LORA antenna 4 via an IPEX connector and connected to the MCU main control unit via a serial port, making communication simple.

[0028] In the actual use of the leaky cable clamp 1, abnormal temperature changes, loosening of the latch, and tilting of the clamp may indicate that the leaky cable clamp 1 has a problem. By real-time monitoring of these parameters and data transmission analysis, problems can be detected in time and corresponding measures can be taken to ensure the normal operation of the leaky cable and the safety of railway communication.

[0029] like Figure 3 and Figure 4As shown, the temperature sensor 2 includes a temperature-sensing element 201, a connecting element 203, and a first protective sleeve. The temperature-sensing element 201 is formed by stacking two metal sheets with different coefficients of thermal expansion. This structure allows the two metal sheets to bend due to their different coefficients of thermal expansion when the temperature changes. Both the connecting element 203 and the temperature-sensing element 201 are sealed within the first protective sleeve, which prevents interference from the external environment and ensures the stability and accuracy of the sensor. One end of the temperature-sensing element 201 is a first temperature-sensing lead 202 fixedly connected to one end of the first protective sleeve, and one end of the connecting element 203 is a second temperature-sensing lead 204 fixedly connected to the other end of the first protective sleeve. The end of the temperature-sensing element 201 away from the first temperature-sensing lead 202 is provided with a moving temperature-sensing contact 205, and the end of the connecting element 203 away from the second temperature-sensing lead 204 is provided with a stationary temperature-sensing contact 206. When the temperature rises to a certain level, the moving temperature-sensing contact 205 contacts the stationary temperature-sensing contact 206, forming a circuit between the first temperature-sensing lead 202 and the second temperature-sensing lead 204. When the temperature decreases, the contacts separate, forming an open circuit. The first temperature-sensing lead 202 and the second temperature-sensing lead 204 are connected to the GPIO of the fixture status acquisition unit via wires, converting temperature changes into electrical signals and transmitting them to the fixture status acquisition unit. In practical applications, the metal sheet of the temperature-sensing element 201 can be made of metals with large differences in thermal expansion coefficients, such as copper and iron, and the first protective sleeve can be made of insulating and corrosion-resistant materials such as plastic.

[0030] Specifically, the switch quantity acquisition unit includes a stationary latching contact and a moving latching contact. The stationary latching contact is fixed to the locking seat 101 of the latch of the leaky cable clamp 1, and the moving latching contact is fixed to the locking tongue 102 of the latch of the leaky cable clamp 1. When the latch of the leaky cable clamp 1 is normally locked, the stationary latching contact and the moving latching contact are in contact, forming a circuit; when the latch is loose or falls off, the contacts separate, forming an open circuit. The stationary latching contact and the moving latching contact are connected to the GPIO of the clamp status acquisition unit through wires, converting the state change of the latch into an electrical signal and transmitting it to the clamp status acquisition unit. In some application scenarios, in order to improve the conductivity and wear resistance of the contacts, the contact surface can be treated with gold plating or other methods.

[0031] like Figure 5 and Figure 6As shown, the attitude sensor 3 is a ball tilt switch, including a rolling seat 301, a conductive shell 303 outside the rolling seat 301, an insulating sleeve 302 between the rolling seat 301 and the conductive shell 303, a conductive ball 304 in the space between the rolling seat 301 and the conductive shell 303, and a second protective sleeve covering the rolling seat 301 and the conductive shell 303. The rolling seat 301 has a groove for positioning the ball. Under normal conditions, the ball is located in the groove, and the rolling seat 301 and the conductive shell 303 are in an open circuit state. When the clamp tilts, the ball rolls out of the groove and contacts the conductive shell 303, thus forming a passage between the rolling seat 301 and the conductive shell 303. A first attitude lead terminal 305 is provided at the rolling base 301, and a second attitude lead terminal 306 is provided at the conductive shell 303. The first attitude lead terminal 305 and the second attitude lead terminal 306 are connected to the GPIO of the fixture status acquisition unit through wires, converting the tilt state of the fixture into an electrical signal and transmitting it to the fixture status acquisition unit. The second protective sleeve can be made of materials with certain elasticity and protective properties, such as rubber, to prevent external objects from damaging the internal structure of the sensor.

[0032] The fixture status acquisition unit is connected to temperature sensor 2, switch quantity acquisition unit, and attitude sensor 3. It receives data from these three sensors and transmits the data to the data central forwarding unit via a wireless transmission module. When the fixture is in normal condition, both the wireless transmission module and the fixture status acquisition unit are in sleep mode to reduce power consumption. When the sensors detect an abnormal situation, they generate an interrupt signal to wake up the wireless transmission module and the fixture status acquisition unit, and upload the data in a timely manner.

[0033] The centralized data forwarding unit is configured with n wireless receiving interfaces and m Ethernet output interfaces. The n wireless receiving interfaces are connected to the card status acquisition units respectively, receiving data from each card status acquisition unit. The m Ethernet output interfaces are connected to the main control unit respectively, transmitting the aggregated data to the main control unit via Ethernet. This hierarchical transmission method can solve the problems of excessive number of substations managed by the main control unit and easy congestion caused by a large number of card status acquisition units directly uploading data.

[0034] The main control unit receives data transmitted from the data central forwarding unit and analyzes and processes the data. It can judge data such as temperature, latch status, and tilt angle based on preset thresholds. When the data exceeds the threshold, it issues corresponding alarm information to remind staff to handle the situation in a timely manner.

[0035] The implementation principle of this embodiment is as follows: This leaky cable clamp status monitoring device uses multiple sensors to monitor multiple key parameters of the leaky cable clamp 1 in real time, and uploads the monitoring data to the main control unit for analysis and processing through hierarchical transmission. This comprehensive and real-time monitoring method can promptly detect potential problems with the leaky cable clamp 1. Compared with the traditional manual inspection method, it greatly improves monitoring efficiency and accuracy, reduces the probability of safety accidents such as leaky cable detachment, and ensures the safe operation of railway communication. At the same time, the use of a low-power wireless communication module and a sleep mode reduces the power consumption of the device, extends the service life of the battery 6, and improves the practicality and economy of the device.

[0036] Example 2 This embodiment differs from the previous embodiments in that it also includes a power supply module, which comprises a battery 6. The power supply module supplies power to the fixture status acquisition unit through an energy management circuit. The battery 6 here can be a high-energy-density, long-life battery such as a lithium battery. The energy management circuit may include a DC-DC chip, which converts the battery 6 voltage to various voltage values ​​required by the circuit. The energy management circuit can be packaged separately from the MCU main control unit and the LoRa module and integrated onto the same circuit board 5.

[0037] The implementation principle of this embodiment is as follows: by setting up a power supply module to provide stable power support for the fixture status acquisition unit, the monitoring device can operate normally without an external power source. The energy management circuit can protect battery 6, extend its service life, reduce maintenance costs, and improve the reliability and stability of the monitoring device.

[0038] Example 3 This embodiment differs from the previous embodiments in that it also includes an energy harvesting module, which comprises a solar panel 7 and a wind power generation device 8. The energy harvesting module charges the power supply module through an energy management circuit. The energy management circuit may also include a BQ25570 chip, which ensures the safe use and stable power supply of the battery 6. The solar panel 7 converts solar energy into electrical energy, and the wind power generation device 8 converts wind energy into electrical energy. Inside the tunnel, the solar panel 7 can harvest the light energy from vehicle headlights, and the wind power generation device 8 can generate electricity using the airflow generated by vehicle movement.

[0039] The implementation principle of this embodiment is as follows: the energy acquisition module enables the monitoring device to achieve energy self-sufficiency, reducing dependence on battery 6 and lowering the frequency of battery 6 replacement. The combination of solar panel 7 and wind power generation device 8 makes full use of the natural energy within the tunnel, improves energy utilization efficiency, further reduces the operating cost of the monitoring device, and also conforms to the concept of energy conservation and environmental protection.

[0040] Example 4 To protect components such as temperature sensor 2, switch quantity acquisition unit, attitude sensor 3, and clamp status acquisition unit, the leaky cable clamp status monitoring device may also include an equipment compartment 9. The equipment compartment 9 is used to install and protect the aforementioned sensors and acquisition units. Its outer shell is made of waterproof, dustproof, and corrosion-resistant materials, effectively resisting the harsh environment inside the tunnel, such as humidity, dust, and chemical corrosion. The equipment compartment 9 is fixedly connected to the leaky cable clamp 1, ensuring the device is stably attached to the clamp. A fixing screw hole 901 can be provided in the equipment compartment 9, through which the leaky cable clamp 1 is firmly connected to the tunnel wall.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
