The control signal output terminal of the regional controller of each auxiliary control module and the control signal input terminal of the controlled device are both connected to a second network control switch, such as Figure 2 shown.

[0026] The working principle and effect of the above embodiment are as follows: the main control module includes a server and a central controller. The digital signal input terminal of the server is the digital signal input terminal of the main control module. The digital signal output terminal of the server is connected to the digital signal input terminal of the central controller. The control signal output terminal of the central controller is the control signal output terminal of the main control module. The main control module performs data judgment according to preset rules through the server and sends the judgment results to the central controller. The central controller generates corresponding preset control instructions based on the received judgment results to control the auxiliary control module and the detection and warning module. The above data judgment rules are all simple comparisons between data and thresholds and do not involve improvements to computer programs.

[0027] The sub-control module includes multiple controlled devices and multiple regional controllers. The controlled devices correspond to the regional devices in a one-to-one relationship. The control signal inputs of the controlled devices and the regional controllers serve as the control signal inputs of the sub-control module. The control signal inputs of the controlled devices are also connected to the control signal outputs of the regional controllers. The digital signal outputs of the controlled devices serve as the digital signal outputs of the sub-control module. By controlling the corresponding controlled devices through the regional controllers, concessional control can be implemented for functional testing of specific controlled devices, i.e., controlling 8 / 9 of the controlled devices to turn off, 1 / 9 to turn on, etc., and outputting digital signals to the detection and warning module. The control of the controlled devices described above is based solely on pre-set rules and does not involve improvements to the computer program.

[0028] The network communication module includes a router, switch, or network interface card. The digital signal input terminal of the router, switch, or network interface card serves as the digital signal input terminal of the network communication module, and the digital signal output terminal of the router, switch, or network interface card serves as the digital signal output terminal of the network communication interface. The network communication module is used to transmit the digital signal output by the secondary control module to the detection and warning module.

[0029] The detection and early warning module includes a detection module and an early warning module. The digital signal input terminal of the detection module is the digital signal input terminal of the detection and early warning module, the digital signal output terminal of the detection module is the digital signal output terminal of the detection and early warning module, the control signal input terminal of the early warning module is the control signal input terminal of the detection and early warning module, and the early warning signal output terminal of the early warning module is the early warning signal output terminal of the detection and early warning module. The digital signal output by the secondary control module is detected by the network tester and network controller of the detection module, and the detection result is output to the main control module. The control signal of the main control module is received by the buzzer and LED device of the early warning module, and a corresponding early warning is issued.

[0030] The detection module includes a network tester and a network controller. The digital signal inputs of the network tester and network controller serve as the detection module's digital signal inputs, while their digital signal outputs serve as the detection module's digital signal outputs. The early warning module includes a buzzer and an LED device. The control signal inputs of the buzzer and LED device serve as the early warning module's control signal inputs, while the early warning signal outputs of the buzzer and LED device serve as the early warning module's early warning signal outputs. A first network control switch is connected between the control signal output of the main control module and the control signal input of each slave control module. A second network control switch is connected between the control signal output of the regional controller of each slave control module and the control signal input of the controlled device. The first network control switch controls the control connection between the main control module and the slave control modules, while the second network control switch controls the control connection between the controlled device and the regional controller. A server, serving as a data processing center, receives digital signals from the network communication module, the detection and early warning module, or other external inputs. The server has a set of simple data-threshold comparison rules pre-set to determine whether received data is abnormal. The central controller receives the judgment results processed by the server and generates corresponding control instructions based on the preset control strategy (such as logic circuit or relay control). These instructions are output in the form of digital signals and are used to control the sub-control module and the detection and warning module. The regional controller of the sub-control module is responsible for monitoring and controlling the corresponding controlled devices. It receives control instructions from the main control module and adjusts the status of the controlled devices according to the instructions (such as turning on, off, adjusting parameters, etc.). The controlled devices perform corresponding operations according to the instructions of the regional controller and feedback the operation results (such as status changes, fault information, etc.) to the regional controller in the form of digital signals, which are then transmitted to the main control module or detection and warning module through the network communication module. The router / switch / network interface card of the network communication module is responsible for transmitting digital signals in the network. It receives digital signals from the sub-control module and transmits them to the detection and warning module or other parts of the main control module via wired or wireless means.

[0031] The detection module of the detection and early warning module includes a network tester and a network controller, which are used to detect the digital signals output by the slave control modules. The network tester verifies the integrity and accuracy of the signals, while the network controller analyzes the signal content to determine whether the controlled devices are operating as expected. When the early warning module detects an abnormal signal or fault, it receives a control signal from the main control module (such as a command transmitted via a relay or logic circuit) and activates a buzzer and LED to provide an audible and visual warning to the user. The first network control switch, located between the main and slave control modules, controls the control connection between them. Closing or opening this switch enables selective control of the slave control modules. The second network control switch, located between the zone controller and the controlled devices, controls the control connection between them. Switching this switch allows selective control of the controlled devices, such as shutting down some devices and enabling others during functional testing. The main control module, through the collaborative operation of the server and central controller, achieves centralized control and efficient management of the entire test bench. The server's built-in data judgment rules are simple and clear, eliminating the need for complex calculations. This reduces system complexity and improves response speed. The sub-control module, through a hierarchical control structure between regional controllers and controlled devices, enables flexible management and precise control of a large number of controlled devices. This structure not only improves system scalability but also facilitates troubleshooting and repair. The network communication module utilizes sophisticated network communication technology to ensure stable digital signal transmission between the various modules of the test bench. This helps improve system reliability and stability and reduces communication failure rates. The detection and early warning module, through real-time digital signal monitoring by the detection module and audible and visual alarm functions by the early warning module, enables real-time monitoring and rapid response to the test bench's operating status. This helps promptly detect and address potential faults, ensuring safe system operation. The network control switch, through flexible switching between the first and second network control switches, enables selective control of the test bench's modules and controlled devices. This not only increases system flexibility but also facilitates specific functional testing and troubleshooting. The aforementioned principles and effects are based on existing technologies and do not require any application modifications.
