Abstract
With the development of hydraulic engineering technology, status monitoring technology of hydraulic system is the effective method to ensure hydraulic equipment working reliably. As a result, the effective hydraulic monitoring and fault diagnosis system is urgent to improve the reliability. A novel electronic control system was proposed in this paper. First, STM32F103ZET6 single chip microcomputer was adopted as the core of data processing chip. Second, temperature sensor, pressure sensor, liquid level sensor and pollution sensor suitable for hydraulic circuit were chosen to measure temperature, pressure, liquid level and pollution. Then the voltage signals according to each sensor were collected by AD7656 chip and were converted to digital signal. The data acquisition and signal process of single chip microcomputer were accomplished by software. Finally, data information of control system was displayed on LCD real-time, and the initial value could be set and adjusted by button, to find the fault position of hydraulic system. This portable hydraulic tester can test hydraulic system, according to the measuring data of temperature, pressure, flow, pollution, the fault location could be diagnosed quickly in the hydraulic system, so the hydraulic circuit fault can be solved quickly and efficiently. The portable hydraulic tester for electric control system of the design can meet the needs of the monitoring of hydraulic system.
