Bottom layer: Based on C # language, integrated control and real-time data collection are achieved through Ethernet, RS485, and CAN bus.
Application layer: Write automatic test cases using CAPL and vTest Studio to achieve a combination of temperature and output conditions, and simulate actual working environments.
The high-voltage electronic control automatic testing system is composed of two cabinets, which are divided into a main cabinet (including the main cabinet) and a secondary cabinet (excluding the main cabinet). The two are connected in parallel using Ethernet to achieve communication purposes. Each cabinet contains six corresponding sets of equipment (power meter, low-voltage power supply, high-voltage DC power supply, DC electronic load), and can perform up to six station tests simultaneously.
