[0023] like Figure 1As shown, this embodiment provides a household water-saving device based on the Internet of Things, which includes a water heater 110, which is connected to a shower head 130 and a faucet 140 through a first pipe 121 and a second pipe 122 respectively; a temperature sensor 150 is installed on the first pipe 121 and the second pipe 122 respectively; the shower head 130 and the faucet 140 are connected to a clean water tank 160 through a seventh pipe 137 and an eighth pipe 138 respectively, and a fourth water pump 174 and a fifth water pump 175 are installed on the seventh pipe 137 and the eighth pipe 138 respectively. A second solenoid valve 182 and a third solenoid valve 183 are respectively provided on the shower head 130 and the faucet 140.

[0024] The first pipe 121 and the second pipe 122 are respectively connected to the third pipe 133, the third pipe 133 is connected to a clean water tank 160, the clean water tank 160 is connected to the water heater 110 through a fourth pipe 134, and the fourth pipe 134 is equipped with a first water pump 171; the third pipe 133 is equipped with a first solenoid valve 181.

[0025] The faucet 140 is matched with a downpipe 190, on which a filter screen 191 is arranged, and the downpipe 190 is connected to a water-saving tank 200, and a first sewage tank 211 and a second sewage tank 212 are connected below the water-saving tank 200, a fifth pipe 135 is connected between the first sewage tank 211 and the second sewage tank 212, and a second water pump 172 is installed on the fifth pipe 135; a first water quality sensor 221 is arranged in the water-saving tank 200, and a second water quality sensor 222 is arranged in the first sewage tank 211; a fourth solenoid valve 184 is arranged between the water-saving tank 200 and the first sewage tank 211, and between the water-saving tank 200 and the second sewage tank 212, respectively. A buzzer 240 is arranged on the first sewage tank 211.

[0026] The first sewage tank 211 is connected to a water outlet pipe 250, and a sixth water pump 176 is installed on the water outlet pipe 250. The second sewage tank 212 is connected to a water pipe 260, and a fifth solenoid valve 185 is installed on the water pipe 260. The second sewage tank 212 is connected to a toilet 270. The second sewage tank 212 is connected to a floor drain 280, and a sixth solenoid valve 186 is installed between the second sewage tank 212 and the floor drain 280.

[0027] The first sewage tank 211 is connected to the clean water tank 160 through the sixth pipe 136, and the third water pump 173 is installed on the sixth pipe 136; the first sewage tank 211 and the second sewage tank 212 are respectively provided with a water level sensor 230;

[0028] All sensors, solenoid valves, and water pumps are connected to a Zigbee wireless communication module based on CC2530, and the Zigbee wireless communication module is connected to the main control chip. The main control chip is STM32F103, which is installed at the water heater 110. Figure 2 As shown in the figure, the Zigbee wireless communication module based on CC2530 includes CC2530 coordination node, CC2530 control node and CC2530 terminal node. Both CC2530 control node and CC2530 terminal node are connected to CC2530 coordination node. CC2530 control node is connected to corresponding buzzer, solenoid valve and water pump. CC2530 terminal node is connected to corresponding water quality sensor, temperature sensor and water level sensor. The coordination node plays the role of gateway in the whole acquisition network and is responsible for the creation and maintenance of the whole ZigBee wireless network. The terminal node is connected to various sensors. The collected data of various sensors are gathered to the coordination node through the wireless network. The coordination node uploads the data to STM32F103 microcontroller through the serial port. STM32F103 is the main control core of the whole system. It will analyze and judge the acquired data and issue control instructions. The instructions issued by STM32F103 are also transmitted to each control node through the coordination node.

[0029] The working principle of this embodiment is as follows:

[0030] When using hot water, when the shower head 130 or the faucet 140 is turned on, the temperature sensor 150 near the water outlet of the shower head 130 or the water outlet of the faucet 140 first monitors the water temperature. The temperature sensor 150 transmits the monitored temperature back to the main control chip using the Zigbee wireless communication module (based on CC2530). The main control chip (STM32F103) determines whether the temperature is within the set range. If it is within the specified range, the main control chip controls the second solenoid valve 182 of the shower head 130 or the third solenoid valve 183 of the faucet 140 to open, and hot water comes out. If it is not within the set range, the first solenoid valve 181 opens, and water flows into the clean water tank 160. The main control chip controls the first water pump 171 to open, and the water in the clean water tank 160 is pumped into the water heater 110 for reheating. This cycle is repeated until the temperature is moderate and the water is released. Or when the faucet 130 / shower head 140 uses cold water, the main control chip controls the fourth water pump 174 / fifth water pump 175 to flow water into the faucet 130 / shower head 140 for reuse.

[0031] During the drainage process of the household faucet 140, when the used water from the faucet flows into the sewer pipe 190, the granular impurities are first filtered out by the filter 191 (the filter 191 is detachable) and then enters the water-saving tank 200. The first water quality sensor 221 in the water-saving tank 200 monitors the water quality of the water in the water-saving tank 200, including the pH value and turbidity. The monitored pH value and turbidity are uploaded to the main control chip using the Zigbee network. The main control chip determines whether the pH value and turbidity are within the set range. If both values ​​meet the standards, the main control chip controls the corresponding fourth solenoid valve 184 to open, and water flows into the first sewage tank 211. Otherwise, the other fourth solenoid valve 184 opens and enters the second sewage tank 212. The first sewage tank 211 stores sewage that meets the standards and can be used to cultivate plants, etc. At the same time, a second water quality sensor 222 is set in the first sewage tank 211. The second water quality sensor 222 transmits data back to the main control chip in real time. If the data does not meet the standards, the second water pump 172 is controlled to pump water into the second sewage tank 212 to ensure that the water quality of the first sewage tank 211 is always up to the standards. The sewage in the second sewage tank 212 is used to flush the toilet.

[0032] The first sewage tank 211 and the second sewage tank 212 are provided with a water level sensor 230. The water level sensor 230 of the second sewage tank 212 transmits data back to the main control chip in real time. When the main control chip determines that the water level does not meet the standard, the main control chip controls the second water pump 172 to obtain water from the first sewage tank 211 first (the water in the second sewage tank 212 cannot flow back to the first sewage tank 211). When the water level in the second sewage tank 212 meets the standard, the second water pump 172 stops working. The water level sensor 230 of the first sewage tank 211 transmits data to the main control chip in real time. When the main control chip detects that the water level of the first sewage tank 211 is not up to standard, the main control chip controls the third water pump 173 to pump water from the clean water tank 160 to the first sewage tank 211, and the water of the first sewage tank 211 is then pumped to the second sewage tank 212. If the water of the clean water tank 160 and the first sewage tank 211 enters the second sewage tank 212, and the water level of the second sewage tank 212 is not up to standard, the main control chip controls the fifth solenoid valve 185 to obtain water through the tap water pipe 260 to supply the flushing side. The working time of the water pump and the opening time of the electric valve need to be set in advance according to the capacity of the sewage tank.

[0033] During the storage process of the first sewage tank 211 and the second sewage tank 212, if the water level of the first sewage tank 211 exceeds the standard, the buzzer 240 will be used to alarm and remind, and the water will be discharged through the outlet pipe 250 of the first sewage tank 211. If the outlet pipe 250 does not discharge water within the specified time, the water will enter the second sewage tank 212 through the second water pump 172. If the water level of the second sewage tank 212 exceeds the standard, the sixth solenoid valve 186 will be opened and the water will flow into the floor drain 280 through the grounding pipe.

[0034] All sensors in the system are connected to the CC250 terminal node. The terminal node sends the signals of each sensor to the main control chip through the coordination node for judgment. The main control chip sends the control signal to each control node through the coordination node. The control node executes the command of the main control chip to control the switch of each electric valve and the operation of the water pump. The power supply is an external battery.

[0035] This embodiment provides a household water-saving device based on the Internet of Things, which uses a temperature sensor 150 to monitor water temperature, controls the inflow and outflow of hot water from the faucet 140 and the shower head 130 when hot water is used, uses different water tanks to store and circulate water flowing out of the water heater 110 and the faucet 140, uses a water quality sensor to store and utilize wastewater in a graded manner, maximizes the water use efficiency of household wastewater, and uses various sensors to enhance the scalability of the water-saving device.

The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
