1. PLC controller: PLC (programmable logic controller) is the core component of the test bench and is used to control the test process, data collection and decision-making. It is capable of performing various test tasks such as lock opening and closing, circuit connectivity and response time according to predefined test specifications.
2. Sensors and actuators: The test bench will be equipped with various sensors, such as pressure sensors, temperature sensors and position sensors, to detect the values of different parameters. Actuators are used to simulate user actions, such as pressing a door lock button or twisting a key.
3. Human-machine interface: This is the interface for the operator to interact with the test bench. It usually includes a touch screen, buttons and indicator lights to start the test, display test results and alarm information.
4. Data collection system: The test bench will record and store the data of each test for subsequent analysis and quality control. This data can be used to monitor production processes, trace product issues and improve product quality.
