Technical Field

[0001] This utility model relates to a water supply system for RVs, and more particularly to an online water quality detection device for a water supply system for RVs. Background Technology

[0002] Traditional RVs typically install their fresh water tanks at the bottom of the vehicle. Due to the limited installation space and harsh operating environment, the water quality in the tank is easily contaminated by the external environment. In practical applications, the water sources for the tanks are diverse, which can threaten the cleanliness and safety of drinking water.

[0003] Currently, the common method for cleaning RV water tanks is to visually inspect or test the water quality using a simple water quality tester before filling the tank with fresh water. However, this testing method cannot guarantee the safety and reliability of the water itself. Utility Model Content

[0009] The power distribution monitoring system is used to perform AD conversion on the electrical signal collected by the pressure gauge, and to control the water pump to start when the water pressure collected by the pressure gauge is less than a set threshold, and to control the water pump to start when the water pressure collected by the pressure gauge is greater than or equal to the set threshold.

[0010] Preferably, a one-way valve is provided on the pipeline between the water-using equipment and the water quality testing module, and the one-way valve is used to deliver water from the outlet of the water quality testing module to the water-using equipment in one direction.

[0011] Preferably, the communication interface module includes an RS485 communication circuit.

[0012] Preferably, it includes a WIFI module and an alarm module, wherein the WIFI module and the alarm module are electrically connected to the main control module respectively.

[0013] In the online water quality monitoring device for the RV water supply system disclosed in this utility model, the clean water tank, the water pump, the water quality monitoring module, and the water-using equipment are sequentially connected to form the water circuit structure of the RV. When the water pump starts operating and supplies water to the water-using equipment, the water quality monitoring module monitors the water quality in the pipeline in real time.

[0021] The water quality detection module 3 is connected to the outlet end of the water pump 2. The water quality detection module 3 is used to detect the water quality data at the outlet end of the water pump 2 and output the corresponding electrical signal.

[0022] Water-using device 4 is connected to the water outlet of the water quality detection module 3;

[0023] Main control module 5;

[0024] The communication interface module 6 is electrically connected between the signal output terminal of the water quality detection module 3 and the main control module 5. The communication interface module 6 is used to transmit the electrical signal output by the water quality detection module 3 to the main control module 5.

[0025] Display unit 7 is electrically connected to the main control module 5;

[0026] The main control module 5 is used to display the water quality data collected by the water quality detection module 3 on the display unit 7.

[0027] In the above-mentioned device, the clean water tank 1, the water pump 2, the water quality detection module 3, and the water-using equipment 4 are connected in sequence to form the water circuit structure of the RV. When the water pump 2 starts running and supplies water to the water-using equipment 4, the water quality detection module 3 detects the water quality in the pipeline in real time. The detection categories include, but are not limited to, water quality TOC, COD, TDS, color, turbidity, and temperature. At the same time, the electrical signal output by the water quality detection module 3 is transmitted to the main control module 5 through the communication interface module 6. Then, the main control module 5 displays the water quality data collected by the water quality detection module 3 on the display unit 7. Compared with the prior art, this utility model can detect and display the water quality of the RV's domestic water in real time, which greatly improves the safety and reliability of the RV's water use.

[0031] In actual operation, the pressure sensor signal from the pressure gauge is sent to the MCU of the power distribution monitoring system for AD conversion and calculation of the corresponding bit value. When the pressure value is lower than the set minimum value, the MCU issues a start command for the water pump, and the water pump starts working. When the pressure value reaches the set maximum value, the water pump stops working, thereby realizing the function of automatic water pressure control.
