Designing and implementation of batch testing equipment for RF electronic seal of smart meter

Abstract

Abstract. for electronic seal of smart meter with special appearance and light weight ,a batch testing equipmentis designed to write program into seal and test automatically , which will increase the testing efficiency of electronic seam installed in meter. The arrange part being consist of vibrating plate , sliding guide and blow pipe realize the auto arrangement of many seals. Then, the seal slide down and stop at the given position with the assistance of photoelectronic sensors and breechblocks. The circuit board write data into seal and finish the testing. Finally ,the seal is put into slider and move into the appointed box according the testing result. The mechanical action are carried out by controller of equipment, such as start, stop, stick in and out, etc. the host computer send writing order to the circuit board. The working state of equipmentcan be shown on the liquid crystal screen installed on the device. The equipmentcan write data to 300 seals every hour automatically without participation of human. the use of this equipmentcan decrease the cost of test operator and increase the efficiency and accuracy of testing.
