Power supply, observation semitrailer car light can determine whether car light and lighting circuit are normal.Circuit of the present invention is simple, delicate structure,
It is easy to carry, it is simple organizes and implements program；No longer need to employ tractor, saved the energy；Due to blocking for no tractor,
Also semi-mounted car light is easily observed.
Further, as shown in Fig. 2 the test switch K1 ..., test switch Kn be relay switch, the test is electric
Road also includes microcontroller, control panel and some triode switch G1...Gn for being used to drive relay switch；Control panel
It is provided with the gating switch of manual/auto selecting switch and each test loop；The gating switch is manually entered control；
Microcontroller by triode switch G1...Gn control test switch K1 ..., test switch Kn；Microcontroller acquisition control face
Switching information on plate, when manual/auto switch is in manual mode, microcontroller is according to the gating switch shape of control panel
The corresponding test switch K1 of state control ..., test switch Kn break-makes, it is described when manual/auto switch is in auto state
Microcontroller automatically control test switch K1 ..., test switch Kn break-makes.
Above-described embodiment is an intelligent tester, can also be tested automatically, testing efficiency with manual test
It is high.
Further, as shown in Fig. 2 present invention additionally comprises current transformer, the current transformer is connected on test power supply
24V output ends, the induced-current that microcontroller passes through A/D transformation and acquisition current transformers., can be with by setting current transformer
Short-circuit test is carried out to semitrailer lighting circuit.When short-circuit conditions occurs in lighting circuit, high current occurs in test loop, electricity
Current transformer can produce high current, and microcontroller is cut off immediately checks loop, and short trouble alarm is sent by indicator lamp.
