[0029] Please refer to the accompanying Figure 1 The present application provides a kind of factory automation water supply system, as shown in the drawings, the water supply system includes well, reservoir 30, water supply pipeline 50 and wireless control terminal. Wherein, well is internally provided with submersible pump;Reservoir 30 is connected with submersible pump by connecting pipeline 40;Reservoir 30 top is provided with first liquid level sensor 31, and reservoir 30 bottom is provided with second liquid level sensor 32;Water supply pipeline 50 connects reservoir 30 and factory water point, and water supply pipeline 50 includes water supply pump 51, under the drive of water supply pump 51, water in reservoir 30 is sent to factory water point;Wireless control terminal is connected with submersible pump, first liquid level sensor 31 and second liquid level sensor 32 communication connection.First liquid level sensor 31 and second liquid level sensor 32 are used for monitoring the water level in reservoir 30 respectively.When water level reaches the high liquid level threshold value pre-set by first liquid level sensor 31, submersible pump will automatically stop working.In addition, submersible pump can also be started and stopped by manual mode, so as to be manually controlled when needed.

[0030] The present application realizes remote receiving of monitoring data of first liquid level sensor 31 and second liquid level sensor 32 by wireless control terminal, and can remotely control the running state of submersible pump.Compared with wired control, wireless control is not limited by distance, and is particularly suitable for the scene that the distance between reservoir 30 and well is far (usually not less than 300 meters).If wired control is used, long distance control line is needed, which brings inconvenience in installation and maintenance.

[0031] In this embodiment, the factory automation water supply system includes a water well, a water storage tank 30, a water supply pipeline 50, and a wireless control terminal. The water well is internally provided with a submersible pump. The water storage tank 30 is connected with the submersible pump through a connecting pipeline 40. The water storage tank 30 is provided with a first liquid level sensor 31 at the top and a second liquid level sensor 32 at the bottom. The water supply pipeline 50 connects the water storage tank 30 and the water use points of the factory. The water supply pipeline 50 includes a water supply pump 51. Under the drive of the water supply pump 51, the water in the water storage tank 30 is sent to the water use points of the factory. The wireless control terminal is in communication connection with the submersible pump, the first liquid level sensor 31, and the second liquid level sensor 32. This design realizes automatic monitoring of the water level of the water storage tank 30. When the water level reaches the high liquid level threshold preset by the first liquid level sensor 31, the submersible pump will automatically stop working, thereby preventing the occurrence of overflow phenomenon, avoiding waste of water resources and unnecessary electricity charges, and having good energy-saving effect. At the same time, when the water level is lower than the low liquid level threshold preset by the second liquid level sensor 32, the submersible pump will automatically start to prevent the occurrence of insufficient water pressure or water shortage, and ensure the effective supply of water resources.

[0032] In some optional embodiments, the water well includes an in-plant water well 11 and an out-of-plant water well 12, and the submersible pump includes a first submersible pump 21 arranged inside the in-plant water well 11 and a second submersible pump 22 arranged inside the out-of-plant water well 12. The first submersible pump 21 and the second submersible pump 22 are respectively connected with the water storage tank 30 through respective corresponding connecting pipelines 40. Compared with the traditional water supply mode of using only a single water well, this embodiment realizes diversification of water sources by simultaneously configuring the in-plant water well 11 and the out-of-plant water well 12. This design effectively avoids the problem of insufficient water supply that may be caused by relying on a single water well, ensures stable water supply during the peak period of water demand, and improves the reliability and flexibility of the system.

[0033] In some optional embodiments, the distance between the out-of-plant water well 12 and the water storage tank 30 is greater than the distance between the in-plant water well 11 and the water storage tank 30. For example, the distance between the out-of-plant water well 12 and the water storage tank 30 is 600 meters, and the distance between the in-plant water well 11 and the water storage tank 30 is 300 meters. The in-plant water well 11 has good response speed and can quickly transport water sources to the water storage tank 30.

[0034] In some optional embodiments, the wireless control terminal can independently control the start and stop of the first submersible pump 21 and the second submersible pump 22. Specifically, the wireless control terminal intelligently selects the start and stop state of the first submersible pump 21 and the second submersible pump 22 according to the water level of the water storage pool 30. When the water consumption is large, the wireless control terminal can simultaneously start the first submersible pump 21 and the second submersible pump 22 to ensure that the water sources in the in-plant water well 11 and the out-plant water well 12 are simultaneously pumped and transported to the water storage pool 30 to meet the high demand. When the water consumption is small, the wireless control terminal can select to start one of the submersible pumps according to the actual demand, thereby optimizing the use efficiency of water resources.

[0035] In some optional embodiments, the factory automation water supply system further comprises a backwater pipeline 60, one end of the backwater pipeline 60 is connected with the water supply pipeline 50 through an overflow valve 70, and the other end is connected with the water storage pool 30. When the water pressure of the corresponding pipeline in the water supply pipeline 50 is high, the overflow valve 70 will automatically open, so that the water in the water supply pipeline 50 can flow back to the water storage pool 30. This design not only helps to keep the pressure of the water system pipeline stable to meet the normal working demand of the water supply pipeline 50, but also effectively prevents system overload, thereby protecting the safe operation of the system and avoiding waste of water resources.

[0036] In some optional embodiments, the water supply pipeline 50 further comprises a pressure sensor in communication connection with the wireless control terminal. The pressure sensor is used to monitor the water pressure in the water supply pipeline 50 and transmit the monitored data to the wireless control terminal. The wireless control terminal can obtain the water pressure of the water supply pipeline 50, and when the obtained water pressure exceeds a preset safety threshold, the system will automatically control the overflow valve 70 to open to allow excess water to flow back to the water storage pool 30, thereby protecting the safety of the system and preventing waste of water resources.

[0037] In some optional embodiments, the first liquid level sensor 31 and the second liquid level sensor 32 are both float ball liquid level sensors, which are a first float ball liquid level sensor and a second float ball liquid level sensor, respectively. The float ball liquid level sensor monitors the liquid level change of the water storage pool 30 through the up and down movement of the float ball.

[0038] In some optional embodiments, the water supply pump 51 is a multi-stage delivery pump.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
