[0021] In order to make those skilled in the art better understand the technical solutions of the present application, the present application will be further described in detail in combination with the drawings.

[0022] Please refer to Figs. 1-2 A domestic water cellar water automatic control system, comprising a domestic water cellar 1, which is used to store domestic water, and in order to ensure stable water supply and avoid water shortage, the water level needs to be monitored in real time, further comprising a PLC automatic control system 2 and a water pump 3 arranged in a pump house away from the domestic water cellar 1, the water pump 3 is connected to the domestic water cellar 1 through a water pipe to pump domestic water into the domestic water cellar 1, a liquid level transmitter 4 is arranged in the domestic water cellar 1 to measure the water level in the domestic water cellar 1, the liquid level transmitter 4 monitors the water level in real time to avoid human negligence and ensure stable water supply.

[0023] The liquid level transmitter 4 is electrically connected between the shielding cable and the PLC automatic control system 2, so that the water level data monitored by the liquid level transmitter 4 in real time is transmitted to the PLC automatic control system 2 in real time, so that the PLC automatic control system 2 makes a relevant response. The PLC automatic control system 2 is electrically connected with the water pump 3 to control the opening and closing of the water pump 3. The PLC automatic control system 2 can process data signals and set low water level lower limit, high water level upper limit, real-time water level, alarm water level and water level correction and the like. For example, the low water level lower limit is set to 3 meters, the high water level upper limit is set to 3.7 meters, and the alarm water level is set to 1.5 meters. When the liquid level transmitter 4 detects that the water level reaches the set limit, the PLC automatic control system 2 will make a real-time response to the data.

[0024] Further, a ladder 5 is arranged in the domestic water tank 1 to facilitate the staff to climb and detect the situation in the domestic water tank 1.

[0025] Further, the ladder 5 is fixedly connected with a horizontal support rod 6, and the end of the horizontal support rod 6 is connected with a circular ring body 7. The circular ring body 7 is used to pass and support the shielding cable of the liquid level transmitter 4. In order to prevent the detection head of the liquid level transmitter 4 from contacting the inner wall of the domestic water tank 1 and ensure the detection stability of the liquid level transmitter 4 in the domestic water tank 1, the circular ring body 7 supported by the horizontal support rod 6 is used to limit the position of the shielding cable of the liquid level transmitter 4 to prevent the liquid level transmitter 4 from being lowered. In this way, the liquid level transmitter 4 can work stably at the appropriate position.

[0026] Further, when the water level in the domestic water tank 1 measured by the liquid level transmitter 4 is higher than the highest water level upper limit, the PLC automatic control system 2 controls the water pump 3 to be closed.

[0027] Further, when the water level in the domestic water tank 1 measured by the liquid level transmitter 4 is lower than the lowest water level lower limit, the PLC automatic control system 2 controls the water pump 3 to be opened.

[0028] Specifically, in this embodiment, when the liquid level transmitter 4 detects that the water level reaches or is higher than the highest water level upper limit of 3.7 meters, the PLC automatic control system 2 controls the water pump 3 to be closed and no longer continues to drain water. When the liquid level transmitter 4 detects that the water level reaches or is lower than the lowest water level lower limit of 3 meters, the PLC automatic control system 2 controls the water pump 3 to be opened to drain water. During the process of draining water, when the liquid level reaches or is higher than the highest water level upper limit of 3.7 meters again, the PLC automatic control system 2 controls the water pump 3 to be closed.

[0029] In addition, the PLC automatic control system 2 is provided with a programming control system, can perform data control, and has a data display screen to observe real-time data such as real-time water level, alarm water level and water level correction. This is a common knowledge for those skilled in the art and will not be described in detail.

[0030] In summary, this control system, through a PLC automatic control system in conjunction with a level transmitter, achieves real-time water level monitoring, allowing users to know the real-time water level at any time, and controls the automatic start and stop of the water pump in the domestic water cellar, thus avoiding uncontrollable factors caused by human intervention.

[0031] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
