Abstract

The invention relates to an interface transformation method for a civil circuit, in particular to a modular interface transformation method for optimizing the civil circuit into an intrinsically safe circuit, which comprises the following steps of: transforming an access point according to the size of an electrolytic capacitor interface in a protection circuit, connecting the access point with the intrinsically safe circuit and keeping the access point in an electrolytic capacitor of the original circuit. According to the modular interface transformation method for optimizing the civil circuit into the intrinsic safety circuit, a protection circuit meeting the intrinsic safety requirement is additionally arranged compared with an original circuit, an electrolytic capacitor of the original circuit is still reserved, and the design requirement of the original circuit is met. The input interface is integrated into an original circuit in a pin welding mode, the defect of fly wire connection can be reduced, and sparks are prevented from being generated; and the two circuits are input in parallel, so that the function of an intrinsic safety circuit is achieved, side effects are avoided, and the problem of civil circuit transformation can be well solved. The maximum size is only 15 mm * 30 mm, and the device is small and flexible. The technical scheme can also be used for design and optimization of other intrinsic safety circuits.

Description

technical field [0001] The invention relates to an interface modification method of a civil circuit, in particular to a modular interface modification method for optimizing the intrinsically safe circuit of a civil circuit. Background technique [0002] At present, most of the circuit boards required by civilians can only meet the daily application requirements; most of the circuit boards required by civilians do not meet the application scenarios of coal and intrinsic safety requirements; if you want to use the circuit boards required by civilians directly for coal and In the scene of intrinsic safety requirements, programming circuits, wiring, plate making, testing and testing are generally required, and the cost and time period are relatively long; if you want to use the scene that meets the intrinsic safety requirements in the coal industry, and do not redesign the circuit boards required for civilian use, The module that originally meets the requirements of intrinsic sa...
