Abstract

The invention provides an acid addition control method, an acid addition controller, an electronic device and an acid addition device. The method comprises the following steps: acquiring pH data detected by N current detection components, wherein the N current detection components are arranged in a same circulating water pool, and N is an integer greater than or equal to 2; if a difference value between pH data detected by two of the current detecting components is greater than a fault threshold value, determining that at least one of the N current detecting components fails; and if a difference value between pH data detected by any two current detecting components is less than the fault threshold value, controlling an acid addition pump used for adding an acid into the circulating water pool to work according to the pH data detected by at least one current detecting component. The method provided by the invention can determine whether or not the current detecting components used at present fail based on difference values of the pH data detected by the detecting components.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to an acid addition control method, an acid addition controller, electronic equipment and an acid addition device. Background technique [0002] In the field of water treatment, the water to be treated can be discharged into the circulating pool through the drainage pipeline. By adding acidic solution to the circulating pool, the pH value of the water can be changed, so that it can meet the recycling standard. [0003] In the existing related technologies, the acid addition process can be automatically controlled by using the acid addition pump, the acid addition controller, the pH detection component, etc., wherein the acid addition controller usually provides feedback based on the pH data detected by the pH detection component However, if the pH detection component breaks down, it is usually difficult to find out in time, which will lead to the situation of adding acid by mistake or...
