[0021] The specific embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present application, and are not used to limit the present application.
[0022] Embodiment one

[0024] When the monitoring result of the end monitoring module is transmitted to other monitoring systems, an end monitoring assembly needs to be added between the end monitoring module and the host computer to which the other monitoring systems belong, and the end monitoring assembly is used to realize the functions of the original cabinet, including power supply and signal transmission of the end monitoring module. To realize the above functions, the end monitoring assembly in the present scheme includes a terminal 1 and a power module 2. After the power module 2 is connected to an external power cable, it supplies power to the terminal 1 and the end monitoring module respectively. The terminal 1 transmits signals to the host computer to which the other monitoring systems belong, and the end monitoring module transmits signals to the terminal 1. Therefore, the current value of the leakage current obtained by the end monitoring module is sent to the host computer after being processed by the terminal 1. The host computer only needs to preset the port for signal transmission between the end monitoring assembly, thereby reducing the cooperation requirement between the host computer and the end monitoring module and improving the adaptability of the end monitoring device.
[0025] In an optional embodiment, the terminal 1 is connected to the end monitoring module through a two-wire bus 3.
[0026] The communication and power supply between the end monitoring module and the terminal 1 are realized through the two-wire bus 3, which simplifies the construction of the cable. When the number of end monitoring modules is large, the end monitoring modules are connected in series through the two-wire bus 3 to form a group, and the terminal 1 only needs one port to realize electrical connection between the terminal 1 and the group of end monitoring modules.
[0027] In an optional embodiment, the terminal 1 includes a two-wire bus 3 module circuit, a processing module circuit and a communication module circuit. The two-wire bus 3 module circuit is coupled to the power module 2, the processing module circuit and the end monitoring module respectively. The processing module circuit is coupled to the host computer via the communication module circuit.
[0028] A group of two-wire buses 3 are two wires, including a positive wire and a negative wire. The two-wire bus 3 module circuits in the terminal 1 and the end monitoring module are coupled to realize communication and power supply through the two-wire bus 3 plugged into the port. Specifically, the two-wire bus 3 module circuit realizes signal transmission from the terminal 1 to the end monitoring module through the change of the power supply voltage in the two-wire bus 3, and realizes signal transmission from the end monitoring module to the terminal 1 through the change of the power supply current.
[0029] The signal of the end monitoring module to the terminal 1 is processed by the processing module circuit and then output to the host computer via the communication module circuit.
[0030] The communication module circuit realizes signal transmission with the host computer through a 422 bus, a CAN bus, a CANFD bus or a wireless mode.
[0031] In an optional embodiment, the end monitoring assembly further includes a switching module 4. The terminal 1 is connected to the switching module 4 through a network cable, and the switching module 4 is connected to the host computer through 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.
