The wireless smoke sensors 6 are used to detect fire signals and send them to the controller 26; The electric valve 8 is fixedly installed on the municipal water supply pipeline 9, and the electric valve 8 is used to detect the water pressure data of the municipal water supply pipeline 9 and send it to the controller 26; The water level sensor 10 is fixedly installed on the top water tank 1. The water level sensor 10 is used to detect the water level data of the top water tank 1 and send it to the controller 26. When the water level of the controller 26 is lower than the safe water level value, the controller 26 controls the electric three-way valve 21 to connect the municipal water supply pipeline 9 and the water tank return pipe 22. The controller 26 controls the water tank return pump 24 to start; When the top water tank 1 needs to be replenished because the water level is lower than the preset value, the water in the municipal water supply pipe 9 flows into the water tank return pipe 22 through the electric three-way valve 21, and then the water in the water tank return pipe 22 is extracted by the water tank return pump 24, and the water passes through the cooling device 23 and is purified by the water purification device 25 before flowing into the top water tank 1; thus, the water replenishment control of the top water tank 1 is realized; The controller 26 is also used to control the opening of the electromagnetic valve 3 4 according to the fire signal and the water pressure data and to control the water in the water storage boiler 17 to replenish the top water tank 1, using the following steps: Step 1: When the controller 26 receives the fire signal sent by the wireless smoke sensor 6, it compares the water pressure data sent by the water pressure sensor 7 to see if it is lower than 0.35Mpa; If not, the controller 26 controls the electric valve 8 and the solenoid valve 3 4 to open; If yes, the controller 26 controls the electric valve 8 to close, and at the same time the controller 26 controls the fire pump 201 to start and the fire electric valve 202 to open, and executes step 2; Step 2, the controller 26 detects whether each wireless smoke sensor 6 sends a fire signal; If yes, the controller 26 controls the opening of the solenoid valve 3 4 connected to the sprinkler pipe 5 on the floor where the wireless smoke sensor 6 is located and the floor above it to be adjusted to 100%; If not, the controller 26 controls the opening of the solenoid valve 3 4 connected to the sprinkler pipe 5 on the floor where the wireless smoke sensor 6 is located and the floor below it to be adjusted to 50%; Step 3: The controller 26 controls the electromagnetic valve 18 to open, the controller 26 controls the electric three-way valve 21 to connect the emergency main water pipe 20 and the water tank return pipe 22, and the controller 26 controls the water tank return pump 24, the cooling device 23 and the water purification device 25 to start; When a fire occurs, water is supplied from the municipal water supply pipe 9, and the water flows from the municipal water supply pipe 9 through the electric valve 8 into the fire water supply pipe 3, and then flows into the sprinkler pipe 5 through the solenoid valve 3 4, and the sprinkler pipe 5 sprays to extinguish the fire; When a fire occurs, the water in the top water tank 1 is supplied, and the water stored in the top water tank 1 flows into the fire water supply pipe 3 after being pressurized by the fire pump 201 through the fire electric valve 202. The controller 26 controls the solenoid valve 3 4 to open and connect the fire water supply pipe 3 and the sprinkler pipe 5. When the controller 26 dispatches the water stored in the water storage type boiling water boiler 17 to supplement the top water tank 1, the water stored in the water storage type boiling water boiler 17 flows into the emergency branch water pipe 19 through the solenoid valve 2 18, and then flows into the emergency main water pipe 20.

[0034] When the present invention is used, the opening of the electromagnetic valve three 4 connected to the sprinkler pipe 5 of the floor where the fire occurs and the floors above it is adjusted to 100%, and the opening of the electromagnetic valve three 4 connected to the sprinkler pipe 5 of the floor where the fire occurs and the floors below it is adjusted to 50%, thereby achieving a reasonable distribution of the water in the top water tank 1. The present invention applies the principle that the fire spreads upward when the floor is on fire, and distributes more water to the fire floor and the floors above it to slow down the spread of the fire.

[0035] The controller 26 is also used to regulate the circulation of the stored water in the top water tank 1 to the water storage type water boiler 17, which adopts the following steps: Step 1: The timer in the controller 26 starts the water circulation instruction every 30 days; Step 2, if the controller 26 executes the water circulation instruction; Step 3, the controller 26 controls the electric three-way valve 13 to connect the water boiler return main pipe 14 and the water tank circulating water pipe 12, and controls the solenoid valve 16 to connect the water boiler return branch pipe 15 and the water inlet of the water storage type water boiler 17; Step 4: if the controller 26 does not execute the water circulation instruction; Step 5, the controller 26 controls the electric three-way valve 13 to connect the municipal water supply pipeline 9 and the water return main pipe 14 of the water boiler; When the controller 26 does not execute the water circulation instruction, the water in the municipal water supply pipe 9 flows into the water return main pipe 14 of the water boiler through the electric three-way valve 13, and then flows into the water return branch pipe 15 of the water boiler from the water return branch pipe 15 through the electromagnetic valve 16 to supply water to the water storage type water boiler 17; When the controller 26 executes the water circulation instruction, the stored water in the top water tank 1 flows into the water purification device 11, and after being purified by the water purification device 11, it flows into the water tank circulation water pipe 12, and flows into the water boiler return water main pipe 14 through the electric three-way valve 13, and then flows into the water boiler return water branch pipe 15 from the water boiler return water main pipe 14. The water from the water boiler return water branch pipe 15 is supplied to the water storage type water boiler 17 through the solenoid valve 16, thereby realizing the circulation of the stored water in the top water tank 1 to the water storage type water boiler 17, avoiding the deterioration of the stored water in the top water tank 1 due to long-term standing and direct discharge, resulting in waste of resources.
