Electronic signal displaying controller with switching and manual reset functions

Abstract

The invention discloses an electronic signal displaying controller with switching and manual reset functions. The controller comprises a controller shell. The controller shell is provided with an upper wiring panel, a display panel and a lower wiring panel, and an MCU processing unit is arranged in the controller shell, is powered by being connected with an alternating current to 12 V voltage module and a 12 V to 3.3 V voltage module, is connected to a high-precision AD of the MCU processing unit by being connected with an operation amplifier amplifying unit through a sensing element, is connected to a control module through a key input module and is connected with a display output module and a relay output module. Data revaluation is carried out through an amplifier and collection of the high-precision AD of the MCU processing unit; the actual value and the alarm value are displayed through two LEDs, and conditions possibly happening are predicted as soon as possible; a module-type power supply and a pi-type filter circuit are good in anti-interference performance, switching reset can be achieved in a plurality of positions, and reset switching can be conveniently carried out.

Description

technical field [0001] The invention specifically relates to an electronic switchable manual reset signal display controller. Background technique [0002] At present, signal control instruments can be well used in various control occasions. However, most of the existing general signal control instruments are automatically reset, and the alarm value cannot be quickly determined when checking, which brings inconvenience to the corresponding investigation. It is not convenient for equipment maintenance, and the anti-interference ability is not very strong. Contents of the invention [0003] In view of the above problems, the technical problem to be solved by the present invention is to provide an electronic switchable manual reset signal display controller which is convenient to handle. [0004] The electronic switchable manual reset signal display controller of the present invention includes a controller housing; the controller housing is provided with an upper wiring pan...
