According to data from the Tianyancha app, Zhongkong Technology (688777) has newly received approval for an invention patent. The title of the patent is “A Method, Device, and Medium for the Interlinked Control of Multiple Units for Desalinated Water Treatment”; the patent application number is CN202211581791.2, and the approval date is November 11, 2025. Patent Abstract: The present invention discloses a method for the coordinated control of multiple units used in desalinated water treatment. Function blocks are created using the ST language, and these blocks are arranged in a specified order to form program pages with various functions. A logic system for desalinated water treatment is developed based on these program pages, and the multiple units utilized for desalinated water treatment are controlled according to this logic system ； Among them, the program page is used to implement single-main-program control, multiple-queue control, pump start/stop control, as well as coordinated control of the anion exchange bed/hybrid exchange bed. This invention incorporates fixed content into the sequence control program to facilitate application. It can record the usage time of a single set of devices, allowing for immediate switching and avoiding the drawbacks associated with manual switching, such as delays in calculation and operational errors. It can automatically calculate the required number of units for operation based on the water tank level and enable switching, and switching between multiple sets of devices can be achieved through program control. By utilizing a certain number of level control devices, the system can maintain the water level in the tank at the desired level even when there are large fluctuations in water consumption, without the need for manual intervention. Since the beginning of this year, Zhongkong Technology has obtained 118 new patent approvals, a 2.61% increase compared to the same period last year. Based on the company’s financial figures for the first half of 2025, the company invested 420 million yuan in research and development during this period, a decrease of 5.54% compared to the previous year.
