The safety detection is one of the key procedures in production of car seats and it is also the quality guarantee of car seats. Safety detection items of QBC car seats include the supplemental inflatable restraint system resistance, passenger presence and safety belt power detection. The detection device adopts the passenger presence detection sensor, digital source meter, data acquisition card detect and collection information. The industrial control computer is applied to process information, judge the results. Finally the detection results are saved into the production database in the enterprise server by internet. The application shows that the detection device has high reliability, high automation level and secured data storage mode.

In this paper, in order to make the simulation of the whole process of electrochemical machining(ECM), the characteristic of electric field and flow field is made detailed analysis in the gap of ECM. Mathematical-physical models of ECM simulation is set up based on the basic theories of electrochemistry, electric field and flow field. And the method of model solution is discussed and researched. So the theoretical base is established of the full process of ECM simulation.

An automatic detection device was developed to measure the frictional resistance force between the tracks on the brackets of car seats. The device adopted the force sensor to measure the action force of the tracks on line. The industrial computer was responsible for processing the data, dynamically drawing the value curve of the meter, collecting the order from the SCM and sending the controlling signal to the SCM. The applications show that the measuring system has the good dynamic performance, high measuring accuracy and reliability.
