Description

Technical Field

[0001] This utility model relates to the field of parking anti-roll technology, specifically to an insulation status monitoring device for a parking anti-roll device. Background Technology

[0002] With the rapid development of the railway industry, anti-rollover devices, as crucial equipment for ensuring safe vehicle parking, are receiving increasing attention for their performance and reliability. The function of anti-rollover devices is to prevent vehicles from moving unexpectedly without control, especially on slopes or when parked. Poor insulation can lead to leakage or short circuits, causing fires and other safety hazards, seriously threatening personnel and property safety. Furthermore, good insulation is a prerequisite for the normal operation of the anti-rollover device's electronic control system. Damaged insulation can cause system malfunctions or failures, preventing the anti-rollover device from providing its proper braking function at critical moments. Real-time monitoring of the insulation status of anti-rollover devices allows for the timely detection of potential electrical safety hazards, preventing accidents caused by electrical faults. Therefore, how to monitor the insulation status of anti-rollover devices is a problem that needs to be solved. Utility Model Content

[0003] Therefore, the technical problem to be solved by this utility model is to overcome the problem that the insulation status of the parking anti-roll device cannot be monitored, which leads to electrical faults and safety accidents, and thus provides a parking anti-roll device insulation status monitoring device.

[0004] This utility model provides an insulation status monitoring device for a parking anti-rollover device. The device includes a parking anti-rollover device, an insulation resistance tester, a PLC controller, a monitoring terminal, and a communication module. The insulation resistance tester is electrically connected to the parking anti-rollover device, the PLC controller is electrically connected to the communication module, and the communication module is communicatively connected to the monitoring terminal.

[0005] The insulation resistance tester is used to measure the insulation resistance and insulation loss current of the parking anti-roll device and transmit the data to the PLC controller.

[0006] The PLC controller is used to convert the insulation resistance and insulation loss current of the parking anti-rollover device into numerical values, and then transmit the converted insulation resistance and insulation loss current to the monitoring terminal.

[0007] The monitoring terminal is used to monitor the insulation status of the parking anti-runaway device based on the numerically converted insulation resistance value and insulation loss current.

[0008] This invention uses an insulation resistance tester to measure key parameters used to determine the insulation status of a parking anti-rollover device, namely insulation resistance and insulation loss current, and transmits them to a PLC controller. The PLC controller is responsible for converting analog signals into digital signals and sending the converted insulation resistance and insulation loss current to a monitoring terminal through a communication module. This enables the analysis and monitoring of the insulation status of the parking anti-rollover device, ensuring its reliability and stability, and allowing for timely detection and handling of insulation faults to prevent electrical safety accidents.

[0009] In one optional implementation, the monitoring terminal includes a host computer management system and a host computer early warning system, and the host computer management system and the host computer early warning system are communicatively connected.

[0010] The host computer management system is used to generate an early warning signal and transmit it to the host computer early warning system when the insulation resistance value after numerical conversion is lower than the first threshold or the insulation loss current after numerical conversion is higher than the second threshold.

[0011] The host computer-based early warning system is used for voice broadcasting based on early warning signals.

[0012] This invention uses a host computer management system to analyze the insulation resistance and insulation loss current of the parking anti-roll device. When the insulation condition is abnormal, an early warning signal is generated and transmitted to the host computer early warning system. This allows the host computer early warning system to issue timely warnings via voice broadcast. Through automated monitoring and early warning, labor costs are reduced, and potential insulation problems can be detected in a timely manner, which helps to prevent major failures.

[0013] In one alternative embodiment, the insulation resistance tester includes a first signal line and a second signal line, which are respectively connected to a grounding rod.

[0014] This invention connects the first and second signal lines of an insulation resistance tester to a grounding rod, which helps to monitor the insulation status of the parking anti-rollover device in real time.

[0015] In one alternative implementation, the device further includes a power supply module for powering the insulation resistance tester, the PLC controller, and the communication module.

[0016] This utility model provides power to multiple electrical components through a power supply module, ensuring their normal operation and guaranteeing real-time monitoring of the insulation status of the parking anti-roll device.

[0017] In one alternative implementation, the power module, insulation resistance tester, PLC controller, and communication module are all located inside the parking anti-runaway device control cabinet.

[0018] This invention optimizes the overall structural layout by placing multiple electrical components inside the parking anti-rollover device control cabinet, facilitating centralized management and avoiding the influence of external environmental factors, thus extending service life.

[0031] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0032] In the description of this utility model, it should be noted that the terms "first", "second" and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0033] The purpose of a parking anti-roll device is to prevent a vehicle from moving unexpectedly without human intervention, especially on a slope or when parked. By monitoring the insulation status of the parking anti-roll device in real time, potential electrical safety hazards can be detected in a timely manner, preventing safety accidents caused by electrical faults.

[0034] This utility model embodiment provides an insulation status monitoring device for a parking anti-rollover device, such as... Figure 1 As shown, the device includes a parking anti-rollover device 1, an insulation resistance tester 2, a PLC controller 3, a monitoring terminal 4, and a communication module 5. The insulation resistance tester 2 is electrically connected to the parking anti-rollover device 1, the PLC controller 3 is electrically connected to the communication module 5, and the communication module 5 is communicatively connected to the monitoring terminal 4. The insulation resistance tester 2 is used to measure the insulation resistance and insulation loss current of the parking anti-rollover device 1 and transmit them to the PLC controller 3. The PLC controller 3 is used to convert the insulation resistance and insulation loss current of the parking anti-rollover device 1 into numerical values ​​and transmit the converted insulation resistance and insulation loss current to the monitoring terminal 4. The monitoring terminal 4 is used to monitor the insulation status of the parking anti-rollover device 1 based on the converted insulation resistance and insulation loss current.

[0035] Specifically, the insulation resistance tester 2 is connected to the protective armor of the main cable and control cable of the parking anti-rollover device 1 via a signal line to measure the insulation resistance value and insulation loss current in the internal circuit of the parking anti-rollover device 1. It is connected to the PLC controller 3 via a shielded 485 serial port data cable to transmit the measured data. The PLC controller 3 converts the analog signals of insulation resistance and insulation loss current into digital signals for subsequent processing and transmission. The PLC controller 3 is connected to the communication module 5 via a fiber optic control line to transmit the converted digital signals to the communication module 5. The communication module 5 can use Bluetooth, ZigBee, or RoLa communication methods, but this is just one example and not a limitation. The monitoring terminal 4 monitors the insulation status of the parking anti-rollover device 1 based on the insulation resistance value and insulation loss current transmitted by the communication module 5. This allows for timely handling of any abnormalities in the insulation status of the parking anti-rollover device 1, ensuring its reliability and stability and preventing electrical safety accidents.

[0036] In one embodiment, such as Figure 1 As shown, the monitoring terminal 4 includes a host computer management system 41 and a host computer early warning system 42. The host computer management system 41 and the host computer early warning system 42 are communicatively connected. The host computer management system 41 is used to generate an early warning signal and transmit it to the host computer early warning system 42 when the insulation resistance value after numerical conversion is lower than a first threshold or the insulation loss current after numerical conversion is higher than a second threshold. The host computer early warning system 42 is used to broadcast the early warning signal via voice.

[0037] Specifically, most of the electrical components in the anti-rollover device 1 operate at 24V, with a permissible leakage current of 1mA. Therefore, the theoretical insulation resistance is 24KΩ, meaning the first threshold is 24KΩ and the second threshold is 1mA. The host computer management system 41 compares the insulation resistance and insulation loss current transmitted by the communication module 5 with the aforementioned first and second thresholds. If the insulation resistance is lower than the first threshold or the insulation loss current is higher than the second threshold, it indicates an abnormal insulation condition in the anti-rollover device 1, potentially indicating an insulation fault. In this case, a warning signal is generated, prompting the host computer warning system 42 to issue a voice broadcast so that staff can handle the situation promptly and prevent electrical accidents.

[0038] In one embodiment, the insulation resistance tester 2 includes a first signal line and a second signal line, which are respectively connected to a grounding rod.

[0039] Specifically, the grounding rod needs to be in full contact with the ground, and there should be a gap between the first signal line and the second signal line, for example, the first signal line and the second signal line should be 3 meters apart, which helps to monitor the insulation status of the parking anti-roll device 1 in real time.

[0040] In one embodiment, such as Figure 1 As shown, the device also includes a power supply module 6, which supplies power to the insulation resistance tester 2, the PLC controller 3, and the communication module 5.

[0041] Specifically, power module 6 can use three-phase AC power to provide stable power output and higher power to multiple electrical components.

[0042] In one embodiment, such as Figure 1 As shown, the power supply module 6, insulation resistance tester 2, PLC controller 3, and communication module 5 are all located inside the parking anti-runaway device control cabinet 7.

[0043] Specifically, multiple electrical components are installed inside the parking anti-rollover control cabinet 7 for centralized management, while avoiding the influence of external environmental factors such as sunlight, dust and rain, thus extending service life.

[0044] In one embodiment, the external cabinet door of the parking anti-rollover device control cabinet 7 is equipped with a display screen 8, a first switch 9, and a second switch 10; the display screen 8 is used to display the insulation status of the parking anti-rollover device 1; the first switch 9 is used to control the opening or closing of the parking anti-rollover device control cabinet 7; and the second switch 10 is used to control the opening or closing of the internal electrical components of the parking anti-rollover device control cabinet 7.

[0045] Specifically, Figure 2 This is a schematic diagram of the external cabinet door of the parking anti-rollover control cabinet provided in this embodiment of the utility model, as shown below. Figure 2 As shown, the external door of the parking anti-rollover control cabinet 7 is equipped with a display screen 8, a first switch 9, and a second switch 10, which reduces the contact between personnel and internal electrical components. The number of second switches 10 can be consistent with the number of electrical components inside the parking anti-rollover control cabinet 7.

[0046] In one embodiment, the display screen 8 includes a wireless communication unit for communicating with the communication module 5 to obtain the insulation resistance value and insulation loss current of the parking anti-rollover device 1 after numerical conversion.

[0047] Specifically, the wireless communication unit of the display screen 8 can establish communication with the communication module 5 using communication methods such as Bluetooth, ZigBee or RoLa, thereby displaying the insulation resistance value and insulation loss current of the parking anti-roll device 1 transmitted by the communication module 5, so that the staff can intuitively understand the current insulation status of the parking anti-roll device 1 through the display screen 8.

[0048] This invention uses an insulation resistance tester to measure key parameters of the parking anti-roll device's insulation status, namely insulation resistance and insulation loss current, and transmits them to a PLC controller. The PLC is responsible for converting the analog signal into a digital signal, and sending the converted insulation resistance and insulation loss current to the monitoring terminal through a communication module. This enables the analysis and monitoring of the parking anti-roll device's insulation status, ensuring its reliability and stability, and allowing for timely detection and handling of insulation faults to prevent electrical safety accidents.

[0049] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
