[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0016] See also Figure 1As shown, an embodiment of the present invention provides a control system for multiple pure water devices, including multiple pure water devices 1 and a control unit 2 for controlling the multiple pure water devices 1. The multiple pure water devices 1 are arranged in parallel, and each pure water device 1 is equipped with a monitor 3 for real-time monitoring of its current water permeability. The pure water outlet pipe of the pure water device 1 is connected to the pure water tank 4, and the pure water tank 4 is equipped with a liquid level sensor 5 for real-time monitoring of its current liquid level. The monitor 3 and the liquid level sensor 5 are both electrically connected to the control unit 2. The control unit 2 is configured to determine the number of pure water devices 1 that currently need to be operated based on the current liquid level of the pure water tank 4, and select the required number of pure water devices 1 for automatic operation based on the current water permeability of each pure water device 1. The selected operation mode is determined by the system settings. If the water permeability of one of the pure water devices 1 does not meet the set requirements, the control unit 2 will automatically alarm and select another pure water device 1 for operation. If the system needs to be applied to a boiler, a hardness leakage alarm device 6 can be installed on the water supply pipe and the pure water outlet pipe of the pure water device 1. The hardness leakage alarm device 6 is electrically connected to the control unit 2. Once the hardness leakage alarm device 6 on the water supply pipe detects a hardness leakage, the recovery rate of the pure water device 1 will be automatically reduced. Once the hardness leakage alarm device 6 on the pure water outlet pipe detects a hardness leakage, the pure water device 1 will be automatically switched to operate and an alarm will be issued (sound and light alarm or SMS alarm, etc.). This not only reduces operating costs, but also contributes to the refined management of the pure water device 1, which is particularly important for boiler safety management.

[0017] Specifically, the pure water tank 4 is preset with multiple operating liquid levels and a stop liquid level in order from low to high. The control unit 2 can select the necessary number of pure water devices 1 for automatic operation according to the current liquid level of the pure water tank 4, and control the pure water device 1 to automatically stop operating when the current liquid level of the pure water tank 4 reaches the stop liquid level. Furthermore, the pure water tank 4 is also preset with a low liquid level alarm liquid level and a high liquid level alarm liquid level. The low liquid level alarm liquid level, multiple operating liquid levels, the stop liquid level, and the high liquid level alarm liquid level are set at intervals from low to high. When the current liquid level of the pure water tank 4 is lower than the low liquid level alarm liquid level, the control unit 2 sends a low liquid level alarm signal and promptly starts the pure water device 1 to fill the pure water tank 4 with water; when the current liquid level of the pure water tank 4 is higher than the high liquid level alarm liquid level, the control unit 2 sends a high liquid level alarm signal and controls the pure water device 1 to stop operating until the alarm is eliminated.

[0018] Taking 4 pure water devices 1 connected in parallel as an example, the pure water tank 4 is preset with a low liquid level alarm level LL, an operating liquid level L1, an operating liquid level L2, an operating liquid level L3, a stop liquid level H and a high liquid level alarm level HH from low to high. The control unit 2 selects the necessary number of pure water devices 1 to automatically operate according to the current liquid level of the pure water tank 4: when the current liquid level of the pure water tank 4 is less than the operating liquid level L1, the 4 pure water devices 1 operate at the same time; when the current liquid level of the pure water tank 4 is greater than or equal to the operating liquid level L1 and less than the operating liquid level L2, 3 pure water devices 1 are selected. Devices 1 operate simultaneously; when the current liquid level of the pure water tank 4 is greater than or equal to the operating liquid level L2 and less than the operating liquid level L3, two pure water devices 1 are selected to operate simultaneously; when the current liquid level of the pure water tank 4 is greater than or equal to the operating liquid level L3 and less than the stop liquid level H, one pure water device 1 is selected to operate; when the current liquid level of the pure water tank 4 is greater than or equal to the stop liquid level H, all pure water devices 1 automatically stop operating; it is worth noting that the above liquid level heights all refer to the height starting from the liquid level sensor 5, not the height starting from the bottom of the pure water tank 4.

[0019] For reference, the monitor 3 can use a timer, counter, flow meter, etc., and the control unit 2 can evaluate the current water permeability of each pure water device 1 based on the current operating time, operating times, or operating flow of each pure water device 1, thereby determining the priority of the pure water devices 1 to be operated, and giving priority to the pure water device 1 with the best water permeability during operation, so as to more evenly suppress the deterioration of each pure water device 1 and balance the water permeability of each pure water device 1.

[0020] Specifically, taking the counter as an example, the control unit 2 can determine the priority of the pure water devices 1 to be operated based on the number of times each pure water device 1 has been operated, giving priority to the pure water device 1 with the fewest number of operations. After the selected pure water device 1 completes one water supply, the priority of each pure water device 1 is re-determined based on the new number of operations, and the pure water device 1 with the fewest number of operations is continuously selected for automatic operation. If multiple pure water devices 1 have the same number of operations, they can be rotated to ensure that each pure water device 1 has an equal opportunity to operate.

[0021] In addition, an automatic operation module (the control unit 2 is electrically connected to the automatic operation module) and a manual operation module can be provided on each pure water device 1. An automatic / manual switching switch is connected between the automatic operation module and the manual operation module, so that the pure water device 1 can switch back and forth between the automatic operation mode and the manual operation mode. The operator can manually start one or more of the pure water devices 1 directly through the automatic / manual switching switch. In the manual operation mode, the pure water device 1 cannot automatically stop operation (even if a high liquid level alarm is triggered), so the operator needs to manually stop it in time according to the actual operation situation.

[0022] This article uses specific examples to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the technical solutions and core ideas of the present invention. Ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some of the technical features therein with equivalents; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
