| Cable is an important part of electrical products. Cable quality directly affects the overall quality of the products, and in the production process of cable quality detection, efficiency directly affects production efficiency. In order to guarantee the quality of products, and to enhance the reliability of product production efficiency, we should improve the quality of the cable testing means.Traditionally people use artificial method in cable quality testing, much time is wasted and the result is bad, and detection fault is hard to avoid. Some special detectors can quickly detect cable quality, but only for certain types of cable for testing, do not have generality. Foreign cable testing equipments are more high-end products, hard to meet the requirements of small and medium enterprises for cost-effective.In view of the present in the manufacture process prevalent cable inspection difficult actual situation, considering that there is no universal performance on the market, cost-effective cable automation testing equipment for the realization of cable detection means of automation, accurate change, standardization and convenient, it is necessary to develop a special type of testing equipment, capable of massive, different specifications, with all kinds of connectors cable for convenient, quick and accurate automatic detection, and whether there are found cable, virtual hige welding, and joint loose, and line loss, etc, to ensure the quality problem of the reliability of cable use.This topic research and development bases on FPGA technology cable automation testing equipment, the equipment has friendly human-machine interface design, uses kelvin four-wire method testing cable voltage, collected by 12 frequency-field technology guarantee with high measurement precision, constant current source for the system to provide test current by universal adapters guarantee system, the different size can be inserted connector order which is based on FPGA for measuring, processor, FPGA experienced in the I/O port resources, have high-speed parallel processing capacity, with high level of integration and high reliability of the hardware characteristics.Cable automation testing equipment based on FPGA fills the blank of current cable automation testing means, the equipment cost is not high, but performance is practical good. The equipment can enormously enhance the enterprise production efficiency and improve product reliability. The equipment has obvious economic benefits and social benefits. |
