Specifically, there are two WBS·Z-type CPU boards, namely WBS·ZA-type CPU board and WBS·ZB-type CPU board; there are two WBS·T-type communication boards, namely WBS·TA-type communication board and WBS·TB-type communication board; there is one WBS·KT-type expansion communication board; there are five WBS·Q-type driver boards, namely WBS·Q1-type driver board, WBS·Q2-type driver board, WBS·Q3-type driver board, WBS·Q4-type driver board and WBS·Q5-type driver board; there are three WBS·C-type acquisition boards, namely WBS·C1-type acquisition board, WBS·C2-type acquisition board and WBS·C3-type acquisition board.

[0033] There are two host units arranged in a dedicated cabinet 1, one above the other. The two host units are a series I host unit and a series II host unit, wherein the series II host unit is a reserved optional host unit. The device also includes a switching unit, which is used to realize the interlocking of the series I host unit and the series II host unit and the switching management of the dual-system communication channels. Specifically, the switching unit includes a WBS·H switching board connected to communicate with the WBS·KT type expansion communication board via an RS422 bus, and the WBS·H switching board is connected to the WBS·Q1 type driver board and the WBS·C1 type acquisition board respectively.

[0034] 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 for the host unit.

[0035] The monitoring unit is used to monitor the system operation status, realize the board fault location display and WBS·Z type CPU board BIOS setting function. Specifically, the monitoring unit includes an industrial computer 10 and a KVM display controller 9, wherein the industrial computer 10 is located above the power supply unit 11, the industrial computer 10 is loaded with monitoring and maintenance software, the industrial computer 10 is connected and communicated with the WBS·Z type CPU board through the serial port RS232 protocol, the WBS·Z type CPU board runs a professional environmental testing software program, and the industrial computer 10 is used to realize data processing; the KVM display controller 9 is located above the industrial computer 10, the KVM display controller 9 is connected and communicated with the industrial computer 10, and the KVM display controller 9 is used to connect the keyboard, display and mouse, so as to realize human-computer interaction.

[0036] When in use, a dedicated environmental testing software program runs in the WBS·Z CPU to realize 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 a total of 64 input switch quantities, which are encapsulated by 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 collection data interaction in the parallel bus mode. The WBS·Z CPU board communicates with the WBS·KT expansion communication board via the parallel bus to expand the 4-way RS485. 22 communication, 4 RS422 are photoelectrically converted in the WBS·H switching board, and the external optical fiber ring connection realizes the self-transmission and self-reception of collected data. After receiving the data, the WBS·Z type CPU board drives the WBS·Q2 type driver board, WBS·Q3 type driver board, WBS·Q4 type driver board and WBS·Q5 type driver board for a total of 64 drive outputs. Each drive output channel corresponds to the collected input switch quantity. The special ring test software program in the WBS·Z type 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 the interaction of human-machine interface.

[0037] 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 filling 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 filling space, and a baffle 12 is also arranged at the bottom of the dedicated cabinet 1.

[0038] The equipment name label plate 2 is used to screen print the name and logo of the cabinet.

[0039] The dedicated cabinet 1 is provided with a display control unit, which is connected to the switching unit and is located above the switching box 4. The display control unit is used to indicate the current working state 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 work indicator light, a series I operation indicator light, a series II power indicator light, a series II work 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.

[0040] like Figures 4 to 5 As shown, the switch box 4 is used to set the switch unit, and indicator lights are respectively set on the front panel and the rear panel of the switch box 4 to realize communication indication. The switch unit contains WBS·H switch board, 4-way optical communication module and other equipment to realize the switching interlocking of the I series host unit and the II series host unit, the switching management of the dual-system communication channels, the photoelectric conversion communication, the indicator light indication on the switch box 4 and other functions.

[0041] Specifically, the two-system interlocking and communication channel switching circuit diagram is as follows Figure 6 As shown, K1 and K2 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 I-YX and II-YX relay node states, and controls the "display control indicator board 3" operation indicator light through the I-YXD+ and II-YXD+ node signals, indicating that the current system is running normally; K3 is a working relay driving coil that is 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 K3 and K2 relays of this system, the read-back node signal I-GZ state is "1", confirming that this system is working in the main system, and the other system K3 relay cannot act because the K4 normally closed node is disconnected, and the read-back II-GZ signal state is "0", confirming that this system is working in the standby system.

[0042] 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.

[0043] 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 is a schematic diagram of the structure in which any host unit is arranged in a corresponding cage, as follows:

[0044] 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.

[0045] The WBS·T communication board is used to add CAN communication function to the WBS·Z CPU board. The IO modules of the WBS·C acquisition board and the WBS·Q driver board communicate with the two WBS·Z CPU boards in the system through CAN communication. The WBS·Z CPU board controls the WBS·T communication board through the AT96 bus, thereby realizing the communication between the two WBS·Z CPU boards in the system.

[0046] The WBS·C acquisition board mainly collects the voltage information of the relay node. When the 0V level is collected, the external relay node is in the disconnected state; when the -24V level is collected, the external relay node is in the closed state. Each WBS·C acquisition board can collect 32 relay node information. The acquisition board sends the collected information to the WBS·Z CPU board through the CANA bus.

[0047] The WBS·Q driver board communicates with the WBS·Z CPU board through the CANA bus. After receiving the valid data sent by the WBS·Z CPU board, the WBS·Q driver board outputs it to the outside according to the valid information in the data packet. When the output end needs to drive the external relay, that is, output "1", the driving point of the output end receives a +24V voltage. When it is necessary to output "0", the voltage at the driving point of the output end is 0. Each WBS·Q driver board can output 16 driving points.

[0048] 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, thereby driving the corresponding node of the other station.

[0049] The WBS·Z type CPU board runs the dedicated environmental testing software program of this device, realizes the system single machine data transmission and reception and system operation status detection, realizes the fault location of each functional module, and sends the fault code to the monitoring unit.

[0050] The industrial computer 10 of the monitoring unit is loaded with monitoring and maintenance software, and receives monitoring data from the WBS·Z type CPU board through the serial port RS232 protocol. The monitoring unit software monitors, parses, stores, and analyzes the equipment operation status, and summarizes the data of series I and series II. The KVM display controller is used for human-computer interaction to realize the equipment status and control information input selection function of the monitoring operation detection device.

[0051] Monitoring and maintenance software design structure Figure 8 As shown in the figure, it consists of three parts: data forwarding program, sqlite data storage and human-computer interface interaction. The data forwarding program is used to receive the test status information sent by the WBS-C system; data storage is implemented using sqlite, and the sqlite storage file uses a storage mode of dividing the library by interface and dividing the table by time to solve the application of instantaneous large data volume and multi-threaded concurrency. The human-computer interface interaction realizes the configuration of test communication equipment, monitoring, query and playback of detailed information of various monitoring data.

[0052] Site configuration functions and display interface are as follows Fig. 9 As shown, it is used to configure the serial port correspondence, connection quantity, communication channel parameters, etc. of the WBS·Z type CPU board and the monitoring unit data of the operation detection device. The serial port connection between the WBS·Z type CPU board and the industrial computer 10 should be consistent with the configuration of the configuration software. After the configuration is completed, click the effective button in the interface, and the configuration takes effect with a successful prompt. Two minutes after the configuration takes effect, you can see real-time monitoring data in the cabinet status interface, switch quantity query, and alarm information query functions.

[0053] The status display interface includes cabinet status, relay status, switch quantity data, alarm quantity data, alarm query, test report, data export and other information.

[0054] The cabinet status displays the operating status of the I and II host units of the current test cabinet, as well as the communication channel status. The status information shows that the red light indicates abnormality and the green light indicates normality.

[0056] S1. Initialize and obtain configuration and address information, and judge the initialization, configuration and address; if the judgment result fails, call the monitoring serial port to send the WBS·Z fault code and end the detection; if the judgment result passes, execute step S2.

[0057] Specifically, the WBS·Z fault code is 0x10.

[0058] S2. Handshake with the WBS·T board to initialize the CAN channel in the system; if the initialization fails, call the monitoring serial port to send the WBS·T fault code and end the detection; if the initialization is successful, execute step S3.

[0059] Specifically, the WBS·T fault code is 0x11.

[0060] S3. Handshake with the WBS·KT board and initialize the RS422 channel; if the initialization is unsuccessful, call the monitoring serial port to send the WBS·KT fault code and end the detection; if the initialization is successful, execute step S4.

[0061] Specifically, the WBS·KT fault code is 0x12.

[0062] S4. Acquire WBS·C acquisition data; if acquisition fails, call the monitoring serial port to send the WBS·C fault code and end the detection; if acquisition succeeds, execute step S5.

[0063] Specifically, the WBS·C fault codes are 0x13 and 0x14.

[0064] S5. Call the inter-station function to send IO data and compare the received IO data with the sent data; if there is an inconsistent channel number, send a channel number fault code and end the detection; if the channel numbers are consistent, call the intra-system CAN channel to send a drive command to WBS·Q.

[0065] Specifically, the channel number fault codes are 0x15 to 0x18.

[0066] S6. The driver reads back to determine whether the data is consistent; if not, a WBS·Q driver channel fault code is sent and the detection ends; if consistent, the process returns to step S2.
