Abstract

The invention discloses a dry contact on-off test system, which comprises a switching module. The switching module comprises an extremely intelligent host chip, a serial port debugging chip, a USB interface and a debugging key. According to the dry contact on-off test system disclosed in the invention, after a transmitted wireless signal is received, 1-10 ms of random seconds are built in 150 ms,signals are forwarded, the method can be used for adding a transfer station when the transmission distance between a wireless controller and a controlled controller is not enough, the on-off state ofa dry contact is tested through a test board, and the problem that SMART-24A and SMART-24BG internet access dry contacts cannot be tested is effectively solved.

Description

technical field [0001] The invention specifically relates to a dry contact continuity test system. Background technique [0002] Wireless communication mainly includes microwave communication and satellite communication. Microwave is a kind of radio wave, and its transmission distance is generally only tens of kilometers. But the frequency band of microwave is very wide, and the communication capacity is very large. Microwave communication needs to build a microwave relay station every tens of kilometers; satellite communication uses communication satellites as relay stations to establish microwave communication links between two or more earth stations on the ground or between mobile bodies. [0003] However, the communication distance of the existing wireless communication system is too short to solve the problem that the dry contacts of the SMART-24A and SMART-24BG network ports cannot be tested, and it is impossible to test whether the dry contacts are on or off. Cont...
