Embodiment Construction

[0047] In order to make the purpose of the invention, the technical solution and its beneficial technical effects clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific implementations described in this specification are only for explaining the present invention, not for limiting the present invention.

[0048] see figure 1 , a work flow diagram of a relay diagnosis method of the present invention, comprising:

[0049] Step S101, sending a control signal to the relay, the type of the control signal includes an enabling signal and a disabling signal;

[0050] Step S102, sending a detection signal on one side of the relay, and receiving a feedback signal on the other side of the relay;

[0051] Step S103, comparing the detection signal and the feedback signal to obtain a comparison result. When the comparison result matches the control signal, the...

Abstract

The present application discloses a method and a system for relay diagnosis. The method includes: transmitting (S101) a control signal to the relay, wherein types of the control signal include an enable signal and a disable signal; applying (S102) a detection signal at one side of the relay, and receiving a feedback signal at the other side of the relay; and comparing (S103) the detection signal with the feedback signal to obtain a comparison result, wherein if the comparison result matches the control signal, the relay is determined as being normal, otherwise, the relay is determined as fault. The present application simply needs to concern whether the relay being diagnosed is enabled or not, and compares the received feedback signal with the applied detection signal to realize the relay diagnosis, thereby avoiding the impacts from other devices in the relay circuit. Thus, the diagnostic efficiency and accuracy can be improved.

Description

technical field [0001] The invention belongs to the technical field of relays, and more specifically, the invention relates to a relay diagnosis method and system. Background technique [0002] In today's world, the energy crisis has attracted more and more attention from people all over the world. Gasoline and diesel, which traditional cars rely on, are all non-renewable energy sources. At present, there are fewer and fewer stocks on the earth. There are more and more wars due to energy issues. The emergence of new energy vehicles can effectively Alleviate the energy crisis and achieve sustainable development. At the same time, the problem of environmental pollution is becoming more and more serious. Gasoline and diesel combustion will produce a lot of sulfide or particulate matter, seriously polluting the atmosphere, and sulfide is easy to form acid rain when it meets rainwater, which will bring other pollution problems. The emergence of this series of problems has put ...
