Description
Technical Field
[0001] This invention relates to the field of end-of-line monitoring, and in particular to an end-of-line monitoring device. Background Technology
[0002] To address the monitoring of grounding at cable termination points, existing online monitoring systems for railway signal cable terminations can monitor the power frequency current, lightning strike count, fault arc, and ambient temperature and humidity at the grounding terminal of each cable termination box. Taking current monitoring as an example, the current transformer in the termination monitoring module is connected to the current sampling circuit via an interface. An external sampling resistor in the sampling circuit converts the current signal from the secondary side of the current transformer into a voltage signal. This voltage signal is then amplified and transmitted to the processing unit of the termination monitoring module. The processing unit calculates the leakage current based on the voltage signal and transmits the result to a remote cabinet. The cabinet contains corresponding terminals and other equipment that centrally display, store, and process the collected results, and issue alarms based on the processing results. The above steps require the rack and the end-to-end monitoring module to work together. That is, the rack needs to have a pre-set port to power the end-to-end monitoring module and transmit signals. When there is a situation where the monitoring results of the end-to-end monitoring module need to be transmitted to other monitoring systems, an end-to-end monitoring component needs to be added between the end-to-end monitoring module and the host computer of other monitoring systems to realize the original rack functions and to power the end-to-end monitoring module and transmit signals up and down. Summary of the Invention
[0003] On the one hand, the present invention provides an end-of-line monitoring device that can transmit the incoming signal of the end-of-line monitoring module and upload the monitoring results to the host computer monitoring system.
[0004] The present invention provides an end-to-end monitoring device, comprising an end-to-end monitoring component and an end-to-end monitoring module. The end-to-end monitoring component includes a terminal and a power module. The power module supplies power to the terminal and the end-to-end monitoring module respectively. The terminal is capable of signal transmission with a host computer, and the end-to-end monitoring module is capable of signal transmission with the host computer via the terminal.
[0005] Furthermore, the terminal is connected to the terminal monitoring module via a two-wire bus.
[0006] Furthermore, the terminal includes a dual-bus module circuit, a processing module circuit, and a communication module circuit. The dual-bus module circuit is coupled to the power module, the processing module circuit, and the terminal monitoring module, respectively. The processing module circuit is coupled to the host computer via the communication module circuit.
[0007] Furthermore, the terminal monitoring component also includes a switching module, the terminal is connected to the switching module via a network cable, and the switching module is connected to the host computer via an optical fiber.
[0008] Furthermore, the terminal monitoring component also includes a circuit breaker located on an external power supply cable connected to the input terminal of the power module.
[0009] Furthermore, the terminal monitoring device also includes a housing, inside which is a mounting plate that is detachably connected to the housing. The terminal and the power module are detachably connected to the mounting plate, respectively.
[0010] Furthermore, the mounting plate has a first plate and a second plate fixed around the first plate, the second plate abutting against the back plate of the housing, so that there is a gap between the first plate and the back plate.
[0011] Furthermore, the second plate is provided with several cable clips along the circumferential direction of the edge of the first plate.
[0012] Furthermore, the enclosure includes a main body and a first door and a second door respectively hinged to the main body. The second door is located between the first door and the enclosure.

[0013] Furthermore, the mounting plate is provided with a branch line at the opening of the housing, and the terminal is connected to the terminal monitoring module via the branch line.
[0014] Beneficial effects
[0015] The end-to-end monitoring component in this solution includes a terminal and a power module. After the power module is connected to an external power supply cable, it supplies power to both the terminal and the end-to-end monitoring module. The terminal transmits signals to the host computer of other monitoring systems, and the end-to-end monitoring module transmits signals to the terminal. Therefore, the leakage current value obtained by the end-to-end monitoring module is processed by the terminal and then sent to the host computer. The host computer only needs to preset the port for signal transmission with the end-to-end monitoring component, which reduces the coordination requirements between the host computer and the end-to-end monitoring module and improves the adaptability of the end-to-end monitoring device.

[0021] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0022] Example 1
[0023] An end-to-end monitoring device includes an end-to-end monitoring component and an end-to-end monitoring module. The end-to-end monitoring component includes a terminal 1 and a power module 2. The power module 2 supplies power to the terminal 1 and the end-to-end monitoring module respectively. The terminal 1 can transmit signals with a host computer, and the end-to-end monitoring module can transmit signals with the host computer via the terminal 1.
[0024] When there is a need to transmit the monitoring results of the end-to-end monitoring module to other monitoring systems, an end-to-end monitoring component needs to be added between the end-to-end monitoring module and the host computer of the other monitoring system. This component performs the functions of the original cabinet, including powering the end-to-end monitoring module and transmitting signals. To achieve this, the end-to-end monitoring component in this solution includes a terminal 1 and a power module 2. The power module 2, connected to an external power cable, supplies power to both the terminal 1 and the end-to-end monitoring module. The terminal 1 transmits signals to the host computer of the other monitoring system, and the end-to-end monitoring module transmits signals to the terminal 1. Therefore, the leakage current value obtained by the end-to-end monitoring module, after being processed by the terminal 1, is sent to the host computer. The host computer only needs to pre-set the port for signal transmission with the end-to-end monitoring component, reducing the coordination requirements between the host computer and the end-to-end monitoring module and improving the adaptability of the end-to-end monitoring device.
[0025] In one alternative implementation, terminal 1 is connected to the terminal monitoring module via a two-wire bus 3.
[0026] Communication and power supply between the terminal monitoring module and terminal 1 are achieved through a two-wire bus 3 connection, which simplifies the cabling setup. When there are a large number of terminal monitoring modules, the above-mentioned terminal monitoring modules can be connected in series and grouped into a group through the two-wire bus 3. Terminal 1 only needs one port to realize the electrical connection between it and the terminal monitoring module group.
[0027] In one optional implementation, terminal 1 includes a dual-bus 3 module circuit, a processing module circuit, and a communication module circuit. The dual-bus 3 module circuit is coupled to the power module 2, the processing module circuit, and the terminal monitoring module, respectively. The processing module circuit is coupled to the host computer via the communication module circuit.
[0028] A set of two-wire bus 3 consists of two wires, including a positive wire and a negative wire. The two-wire bus 3 module circuit in the terminal 1 and the terminal monitoring module communicates and supplies power through the two-wire bus 3 plugged into the port. Specifically, the two-wire bus 3 module circuit realizes the signal transmission from the terminal 1 to the terminal monitoring module through the change of the power supply voltage in the two-wire bus 3, and realizes the signal transmission from the terminal monitoring module to the terminal 1 through the change of the power supply current.
[0029] The terminal monitoring module processes the signal from terminal 1 through the processing module circuit and then outputs it to the host computer through the communication module circuit.
[0030] The communication module circuit transmits signals to the host computer via 422 bus, CAN bus, CANFD bus or wireless means.
[0031] In one optional implementation, the terminal monitoring component further includes a switching module 4, with the terminal 1 connected to the switching module 4 via a network cable, and the switching module 4 connected to the host computer via an optical fiber.
[0032] The switching module 4 has multiple fiber optic ports and multiple network cable ports. Terminal 1 is connected to the network cable port of the switching module 4, enabling the signal output from terminal 1 to be transmitted to the host computer via fiber optic cable. The control module 10 on the second door 11 is connected to the network cable port of the switching module 4, enabling signal transmission between the switching module 4 and terminal 1.
[0033] In one alternative implementation, the terminal monitoring component further includes a circuit breaker 5 located on an external power supply cable connected to the input terminal of the power module 2.
[0034] Example 2
[0035] An end-to-end monitoring box is provided. The box body 8 is equipped with an end-to-end monitoring device according to one embodiment. The box body 8 is equipped with a mounting plate 7, which is detachably connected to the box body 8. The terminal 1 and the power module 2 are detachably connected to the mounting plate 7 respectively.
[0036] Terminal 1, power module 2, switching module 4, and circuit breaker 5 are respectively mounted on mounting plate 7 with screws. The purpose of mounting plate 7 is to facilitate the installation and removal of the terminal monitoring device in the enclosure 8. In this solution, after the terminal 1, power module 2, switching module 4, and circuit breaker 5 are installed on mounting plate 7, the mounting plate 7 can be placed into the enclosure 8 and fixed in place. This avoids the problem of inconvenience in the installation and wiring of terminal 1, power module 2, switching module 4, and circuit breaker 5 due to the narrow space inside the enclosure 8.
[0037] In one alternative embodiment, the mounting plate 7 has a first plate 12 and a second plate 13 fixed around the first plate 12, the second plate 13 abutting against the back plate of the housing 8 such that there is a gap between the first plate 12 and the back plate.
[0038] Terminal 1, power module 2, switching module 4 and circuit breaker 5 are mounted on the wall of the first plate 12 facing the cavity opening of the housing 8 by screws. The second plate 13 is formed by bending the edge of the first plate 12. It serves as a reinforcing rib and supports the first plate 12. The first plate 12 is fixed to the back plate of the housing 8 by studs. One end of the studs is welded to the back plate of the housing 8. The back plate faces the cavity opening. Holes are made on the first plate 12. When the first plate 12 enters the housing 8 through the cavity opening and approaches the back plate of the housing 8, the studs pass through the holes during the approach. After the second plate 13 abuts against the back plate of the housing 8, the first plate 12 is pressed by the nut engaging the studs, thus fixing the first plate 12 to the housing 8. At this time, there is a gap between the first plate 12 and the back plate. The existence of the gap prevents the screws from piercing the back plate of the housing 8 when the terminal 1 and others are engaged with the first plate 12 by screws. This prevents rainwater from entering the housing 8 through the perforations on the back plate, especially on the mounting plate 7, ensuring the relative sealing of the housing 8.
[0039] In one alternative embodiment, the second plate 13 is provided with a plurality of cable clips 14 circumferentially along the edge of the first plate 12.
[0040] When the power supply cable or signal transmission cable inside the enclosure 8 is long, it is fixedly arranged on the second plate 13 by the cable clip 14. The second plate 13 is arranged circumferentially along the edge of the first plate 12. Therefore, the cable is arranged along the edge of the first plate 12, extends out from the corresponding port of the terminal 1, and extends to the network cable port of the switching module 4.
[0041] The first board 12 in this solution is also provided with cable clips 14. The power supply cable from the power module 2 to the terminal 1 and the switching module 4 is fixed on the first board 12 by the cable clips 14. The signal transmission cable between the terminal 1 and the branch line 6 is also fixed on the first board 12 by the cable clips 14.
[0042] In one optional embodiment, the enclosure 8 includes an enclosure body and a first door 9 and a second door 11 respectively hinged to the enclosure body. The second door 11 is located between the first door 9 and the enclosure 8. A control module 10 is provided on the second door 11. The power module 2 is connected to the control module 10 via a cable. The terminal 1 is coupled to the control module 10.
[0043] The control module 10 includes a display screen, lights, and interactive devices, which can be integrated into a single touchscreen. The signal transmission port of the control module 10 is connected to the network cable port of the switching module 4, enabling signal transmission with the terminal 1 through the switching module 4. The operator can control the terminal 1 through the control module 10 and also display the monitoring data collected by the terminal monitoring module from the terminal 1.
[0044] The control module 10 is fixed to the second door 11. The screen of the control module 10 is located on the side of the second door 11 facing the first door 9. The signal transmission port of the control module 10 is located on the side of the second door 11 facing the main body of the box. The mounting plate 7 is located inside the cavity of the main body of the box. The second door 11 corresponds to the cavity opening of the box 8 and is used to close the cavity of the main body of the box after closing. The first door 9 is used to protect the screen of the control module 10. The first door 9 needs to be opened first when operating the control module 10.
[0045] In one alternative embodiment, the mounting plate 7 is provided with a branch line 6 at the opening of the housing 8, and the terminal 1 is connected to the terminal monitoring module via the branch line 6.
[0046] The branch line 6 is mounted on the first plate 12 of the mounting plate 7 by screws. A set of two-wire buses 3 extending from one of the two-wire bus 3 ports of the terminal 1 is connected to the input terminal of the branch line 6, dividing the one-wire bus 3 into two groups through the branch line 6. The terminal 1 has multiple two-wire bus 3 ports, each port is electrically connected to a set of two-wire buses 3, and a set of two-wire buses 3 is electrically connected to multiple monitoring modules. Each terminal monitoring module has a unique address. When a terminal monitoring module is connected to the terminal 1, it registers with the terminal 1, such as terminal monitoring module a, terminal monitoring module b, terminal monitoring module n, etc. Each terminal monitoring module collects the parameter information of the terminal grounding line and the terminal environment according to the set frequency and caches it in the MCU. The terminal 1 sends a query message containing address information to each terminal monitoring module in the group, such as sending query message a containing the address information of terminal monitoring module a. After receiving the query message a, each terminal monitoring module performs address matching. If the terminal monitoring module a matches successfully, it sends the parameter information of the terminal grounding line and the terminal environment that the monitoring module a is cooperating with to the terminal 1, containing the address information of monitoring module a.
[0047] Terminal 1 continuously sends query information containing address information of terminal monitoring modules a to n at certain time intervals. For example, query information a is sent at the first time, query information b is sent at the second time, query information n is sent at the nth time, and query information a is sent at the (n+1)th time, and so on in a cyclical manner.
