[0020] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0021] A WBS-C inter-station transmission system operation detection device, combined with Figures 1-2 As shown, it includes a dedicated cabinet 1, in which a host unit and a monitoring unit are arranged.

[0022] The host unit includes a WBS·Z type CPU board, a WBS·T type communication board, a WBS·KT type extended communication board, a WBS·Q type driver board and a WBS·C type acquisition board. Among them, the WBS·Z type CPU board, the WBS·T type communication board and the WBS·KT type extended communication board are connected and communicated through the set backboard AT96 parallel bus; the WBS·T type communication board, the WBS·Q type driver board and the WBS·C type acquisition board are connected and communicated through the CAN bus. Specifically, there are two WBS·Z-type CPU boards, namely WBS·ZA CPU board and WBS·ZB CPU board; there are two WBS·T-type communication boards, namely WBS·TA communication board and WBS·TB communication board; there is one WBS·KT expansion communication board; there are five WBS·Q-type driver boards, namely WBS·Q1 driver board, WBS·Q2 driver board, WBS·Q3 driver board, WBS·Q4 driver board and WBS·Q5 driver board; there are three WBS·C-type acquisition boards, namely WBS·C1 acquisition board, WBS·C2 acquisition board and WBS·C3 acquisition board.

[0023] Two host units are installed one above the other in a dedicated cabinet 1. These two host units are the Series I host unit and the Series II host unit, with the Series II host unit being a reserved optional unit. The system also includes a switching unit, which is used to implement interlocking between the Series I and Series II host units and manage communication channel switching between the two systems. Specifically, the switching unit includes a WBS·H switching board that communicates with the WBS·KT expansion communication board via an RS422 bus. The WBS·H switching board is connected to the WBS·Q1 driver board and the WBS·C1 acquisition board, respectively.

[0024] The host unit also includes a WBS·Y board, which is used to provide 5V and 12V power supplies. A power supply unit 11 is also provided at the bottom of the dedicated cabinet 1, which is used to provide 24V isolated power supply to the host unit.

[0025] The monitoring unit is used to monitor the system's operating status, locate and display board faults, and configure the WBS·Z-type CPU board's BIOS settings. Specifically, the monitoring unit includes an industrial computer 10 and a KVM display controller 9. The industrial computer 10 is located above the power supply unit 11 and communicates with the WBS·Z-type CPU board via the RS232 serial port. The industrial computer 10 is used for data processing. The KVM display controller 9 is located above the industrial computer 10 and communicates with the industrial computer 10. The KVM display controller 9 is used to connect to the keyboard, monitor, and mouse, enabling human-computer interaction.

[0026] When in use, the WBS·Z CPU realizes the data transmission and reception and detection operation of the system stand-alone. The system data flow and functional module are described as follows: the WBS·C2 acquisition board and the WBS·C3 acquisition board collect 64 input switch quantities in total, which are encapsulated in the internal safety protocol and sent to the WBS·T communication board via the CAN bus. The WBS·T communication board and the WBS·Z CPU board realize the exchange of collected data via the parallel bus. The WBS·Z CPU board communicates with the WBS·KT expansion communication board via the parallel bus to expand the 4-way RS42 2 communication, 4 RS422 switches are photoelectrically converted in the WBS·H switching board, and the collected data is automatically transmitted and received by an external optical fiber loop. After receiving the data, the WBS·Z CPU board drives the WBS·Q2 driver board, WBS·Q3 driver board, WBS·Q4 driver board and WBS·Q5 driver board, totaling 64 drive outputs. Each drive output channel corresponds to the collected input switch value. The WBS·Z CPU realizes fault location in each link of data transmission and reception, and sends it to the monitoring unit in the form of fault code to realize human-machine interface interaction.

[0027] The dedicated cabinet 1 adopts a 800mm*600mm*2000mm (depth×width×height) dedicated cabinet, including an equipment name label 2, a display control label 3, a switch box 4, an I series label 5, an I series cage 6, a II series label 7, a II series cage 8 and a filler space, which are arranged from top to bottom. The KVM display controller 9, the industrial computer 10 and the power supply unit 11 are arranged in sequence below the filler space. A baffle 12 is also provided at the bottom of the dedicated cabinet 1.

[0028] The equipment name plate 2 is used to screen print the name and logo of the cabinet.

[0029] The dedicated cabinet 1 is provided with a display control unit, which is connected to the switch unit and is located above the switch box 4. The display control unit is used to indicate the current working status of the device and the power switch and operation switch of the I series host unit and the II series host unit. The display control indicator board 3 is connected to the display control unit. Specifically,Figure 3 As shown, the display control indicator panel 3 is provided with a series I power indicator light, a series I working indicator light, a series I operation indicator light, a series II power indicator light, a series II working indicator light, a series II operation indicator light, a series I power switch, an inter-series switching switch and a series II power switch, which are connected to the display control unit.

[0030] like Figures 4-5 As shown, switch box 4 is used to set up the switching unit. Indicator lights are located on the front and rear panels of switch box 4 to provide communication indication. The switching unit houses a WBS·H switch board, a four-way optical communication module, and other equipment, enabling interlocking between the Series I and Series II host units, dual-system communication channel switching management, optoelectronic conversion communication, and indicator lights on switch box 4.

[0031] Specifically, the two-system interlocking and communication channel switching circuit diagram is as follows Figure 6 As shown, K1 and K1 are running relays controlled by the I-YXXQ and II-YXXQ relay operation pickup signals output by the two series host units respectively. The relay pickup host unit reads back the status of the I-YX and II-YX relay nodes, and controls the operation indicator light of the "display control panel 3" through the I-YXD+ and II-YXD+ node signals, indicating that the current system is operating normally; K3 is the working relay drive coil connected in series with a group of normally closed nodes of K2 of this system and K4 of another system. When one system is powered on first to complete the action of the K3 and K2 relays of this system, the read-back node signal I-GZ status is "1", confirming that this system is working in the main system. The K3 relay of the other system cannot act because the normally closed node K4 is disconnected, and the read-back II-GZ signal status is "0", confirming that this system is working in the backup system.

[0032] The two-system interlocking circuit links the communication channel switching circuit through the relay node signal I / II-QH. System I works when the main system I / II-QH signal outputs 24V to drive K5, K6, K7, and K81. The RS422 signal of system I is output through the relay middle node. System II works when the main system I / II-QH signal outputs 0. The RS422 signal of system II is output through the relay middle node.

[0033] The I series marking plate 5 is used to mark the I series, the I series cage 6 is used to set the I series host unit, the II series marking plate 7 is used to mark the II series, and the II series cage 8 is used to set the II series host unit. Figure 7 The figure shows a schematic diagram of the structure in which any host unit is arranged in a corresponding cage, as follows:

[0034] The WBS·Y board provides 5V power for the WBS·Z CPU board, WBS·T communication board, and WBS·KT expansion communication board of this system; the WBS·Y board provides 12V power for the communication module in the switching unit.

[0035] The WBS·T Communication Board adds CAN communication capabilities to the WBS·Z CPU Board. The I / O modules of the WBS·C Acquisition Board and the WBS·Q Driver Board communicate with the two WBS·Z CPU Boards within the system via CAN. The WBS·Z CPU Board controls the WBS·T Communication Board via the AT96 bus, enabling communication between the two WBS·Z CPU Boards within the system.

[0036] The WBS·C acquisition board primarily collects voltage information from relay nodes. When a 0V voltage level is detected, the external relay node is disconnected; when a -24V voltage level is detected, the external relay node is closed. Each WBS·C acquisition board can collect information from 32 relay nodes. The acquisition board transmits this information to the WBS·Z CPU board via the CANA bus.

[0037] The WBS·Q driver board communicates with the WBS·Z CPU board via the CANA bus. After receiving valid data from the WBS·Z CPU board, the WBS·Q driver board outputs data based on the valid information in the data packet. When an output terminal is required to drive an external relay (i.e., output "1"), the output terminal's drive point receives a +24V voltage. When a "0" is required, the output terminal's drive point receives a voltage of 0. Each WBS·Q driver board can output 16 drive points.

[0038] The WBS·KT expansion communication board expands 8 RS422 serial ports on the AT96 bus of the WBS·Z CPU board. The WBS-C system is connected to the 4-channel fiber optic conversion module on the switch box 4 through 4 RS422s, and then communicates with the other station, sending the collection information of this station to drive the corresponding node of the other station.

[0039] The WBS·Z type CPU realizes the data transmission and reception of the system stand-alone machine and the detection of the system operation status, locates the fault of each functional module, and sends the fault code to the monitoring unit.

[0040] When the utility model is in use, the host unit and the monitoring unit are provided, which can not only realize the operation detection of the WBS-C inter-station transmission system, but also realize the human-computer interaction functions of equipment status analysis and fault location.
