Problems solved by technology

[0002] In the water conservancy industry, when the power grid is cut off due to maintenance or failure, in order to enable users to use water normally, the battery can be used to supply power for 1 to 2 working days to ensure that the water supply equipment can be measured and operated normally. Automatically close the water valve to stop the water supply to ensure that the metering equipment loses its metering function due to the low voltage of the battery, so that users continue to use water and cause metering errors. At present, there is no suitable voltage module that can detect battery discharge on the market

Abstract

The invention, which relates to the technical field of voltage detection, particularly discloses a voltage detecting module comprising a base, a main board and an upper cover. The main board is fixedbetween the base and the upper cover. A voltage detecting module circuit is arranged on the main board and includes a DC12V battery voltage detection module, a DC24V battery voltage detection module,and an AC220V voltage detection module; and a relay controlled by each module has two groups of contacts. The voltage detecting module has the following advantages: the power failure and the power-onstate of the power grid can be detected and early warning is carried out under the condition of the power failure; the electrical equipment can obtain power from the battery continuously after power failure of the power grid; the battery discharge voltage can be detected and when the battery discharge voltage is lower than a set value, an actuator is turned off and thus a phenomenon that the metering device fails to work because of the too low battery discharge voltage is avoided; and the voltage detecting module has the two kinds of DC12V and DC24V battery voltage detection functions, so thatvarious possibilities of battery power supply in the water conservancy industry are realized.

Description

technical field [0001] The invention relates to the technical field of voltage detection, in particular to a voltage detection module. Background technique [0002] In the water conservancy industry, when the power grid is cut off due to maintenance or failure, in order to enable users to use water normally, the battery can be used to supply power for 1 to 2 working days to ensure that the water supply equipment can be measured and operated normally. Automatically close the water valve to stop the water supply, to ensure that the metering equipment loses its metering function due to the low voltage of the battery, so that users continue to use water and cause metering errors. Currently, there is no suitable voltage module that can detect battery discharge on the market. Contents of the invention [0003] The purpose of the present invention is to provide a voltage detection module suitable for water conservancy industry powered by batteries, which has two battery voltage d...
