Abstract

The invention discloses a high-voltage interlocking device, comprising a high-voltage interlocking signal detection and transmission module (1); in the high-voltage interlocking signal detection and detection module (1), an illumination tube (4) is adopted to convert an electrical signal into an optical signal for transmission, through the transmission of a high voltage interlocking optical fiber(5), a photoelectric converter (6) is adopted to convert the returned optical signal into an electrical signal. With the above technical scheme, the optical signal is more stable, and the transmissionof the optical signal is not easy subjected to electromagnetic interference, and the optical signal is used instead of the electrical signal for interconnection outside the module in a complex environment, and then the electrical signal generated by a photoelectric coupling circuit is adopted inside a detection module for detection, and the process is more accurate; after the photoelectric coupling, the strength of the electrical signal is detected, and the entire circuit sealing level can be judged, thereby judging the sealing performance of an overall system; the simple optical signal can be used as the interlocking signal, and an interlocking signal generation and detection circuit is no longer complicated.

Description

technical field [0001] The invention belongs to the technical field of new energy vehicles. More specifically, the present invention relates to a novel high voltage interlock device. Background technique [0002] Under the influence of increasingly severe environmental changes in the 21st century, the relevant departments of the national automobile industry have put forward the requirements for automobile emissions to transition to the National VI B requirements by 2020; major automobile OEMs have stepped up the introduction of electrification and intelligence, and electrification and intelligence The basis of modernized control is the high maturity and high error-proofness of automotive electrical hardware. [0003] In the high-voltage interlocking circuit of automotive electrical hardware, electrical signal transmission is generally used, and the sealing condition of the circuit is judged by detecting the strength of the electrical signal. However, its detection is easily...
