[0002] In power plants, it is necessary to detect the chemical ions contained in boiler water, demineralized water and steam. In order to ensure the stability and reliability of the detection, multi-point detection is usually required, and the detection instruments are single-point detection. If each detection point To configure a detection instrument, it is necessary to purchase a large number of expensive test instruments, which not only increases the production cost of the power plant, but also increases the maintenance of the equipment

The invention relates to a multichannel distributor for water sample detection. The multichannel distributor uses new design structure. A one-to-one control relation is established between digital output paths and analog output paths in order that host processing systems and different water samples are associated one to one. Therefore, in detection statistic operation of multiple different water samples, the equipment cost and maintenance workload are reduced to the utmost extent. Correspondingly, the invention also designs two application control methods for the designed multichannel distributor for water sample detection. For the detection statistic operation of the multiple different water samples, the methods achieve high-efficient and convenient operation processes and greatly improve work efficiency.
Description
technical field [0001] The invention relates to a multi-channel distributor for water sample detection and an application control method, belonging to the technical field of water sample detection. Background technique [0002] In power plants, it is necessary to detect the chemical ions contained in boiler water, demineralized water and steam. In order to ensure the stability and reliability of the detection, multi-point detection is usually required, and the detection instruments are single-point detection. If each detection point To configure a testing instrument, it is necessary to purchase a large number of expensive testing instruments, which not only increases the production cost of the power plant, but also increases the maintenance amount of the equipment. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a multi-channel distributor for water sample detection, which can minimize the cost of equipment and t...
