Aiming at the problem of inaccurate data measurement and operation niggling of pressure-tight test operation of tank truck,the sys-tem architecture, technical parameters and test control were researched. A method to realize the automatic control of the experiment by con-trolling the electromagnetic valve, the sensor and the pressure test pump was explored. Computer measurement and control system of pressure-tight test of tank truk based on the microcomputer technology, sensor technology and measurement technology. After the analysis of the whole test system,the relationship between the test lines, microcomputer control system and computer management system was established. The de-sign of the test pipeline, the design of the circuit of the microcomputer control system, the processing of the test data and the method of auto-matic test control were analyzed. The results show that the system can effectively complete the test process, improve accuracy of the test data, generate the test report and reduce working strength of the operators.
