In fields such as Aero-Space, railway, boats and ships, engineering technical personnel are in the time carrying out leader cable conduction detection, adopt the conductive device such as conducting bell, according to system wiring graph of a relation, conductive device probe is connected to leader cable two ends, conducting bell rings represents that leader cable loop is logical.This detection method, in implementation process, has following shortcoming:
1. the probe lead that in testing process, conductive device need to be drawn certain length, particularly lays the application scenario of channel architecture complexity in remote detection and leader cable, is not easy to implement;
2. can not detect the size of leader cable resistance;
3. in loop, there is larger electric current to flow through, easily leader cable itself is caused to damage.
Summary of the invention
The object of the invention is:
A kind of separate wires cable detecting device and method are provided.

Embodiment
With a specific embodiment, the present invention is described in further details below, the turn on process of a wire in certain type electrical-mechanical system, step is as follows:
1. the connection of device A: probe A is accessed to tested wire one end, will press from both sides altogether A and access near metal body nearby;
2. the connection of device B: probe B is accessed to the tested wire other end, will press from both sides altogether B and access near metal body nearby;
3. starter gear A detects: put through starting switch, first use can be set conducting resistance threshold value by key-press module.Put through detector switch, current direction is power module → current-limiting resistance → probe A → tested wire → probe B → shorting stub → press from both sides altogether B → metal body → press from both sides altogether A → power module.Micro controller in device A, gather the voltage drop on current-limiting resistance by A/D module, through aggregation of data analyzing and processing and consider the impact of metal body resistance value, the resistance value that finally converses tested wire is shown in display module, and with conducting resistance threshold value relatively after, determine whether to drive hummer and pilot lamp to send corresponding information.
