The different water supply modes correspond to different water spray modes of the water spraying device 152, for example, when the water supply device 122 is communicated with the first water tank 1525, the water supply device 122 directly supplies water to the first water tank 1525 so as to keep the water level in the first water tank 1525 normal, so that the spray pump 1521 can continuously spray the water, the spray distance is unstable due to unstable liquid level of the first water tank 1525, the spray flow is large and small, the actual effect of fire-fighting operation is affected, and the spray pump 1521 and the water cannon connected with the spray pump can fully play the best effect of pump cannon matching.

In this case, the fire-fighting sprinkler 15 may further include a first tank water level sensor 1526 and a water-spraying flow sensor 1527, both of which are communicatively connected to the water-spraying controller 151; the water spraying state information includes a water spraying flow rate and a first water tank water level, the first water tank water level sensor 1526 is disposed in the first water tank 1525 and is configured to detect a water level in the first water tank 1525 and generate a first water tank water level, the water spraying flow rate sensor 1527 is disposed in the water spraying pump 1521 and is configured to detect a flow rate of water sprayed by the water spraying pump 1521 and generate a water spraying flow rate, the water supplying state information further includes a water supplying flow rate, the fire-fighting water supplying machine 12 further includes a water supplying flow rate sensor 1225 communicatively connected to the water supplying controller 121, and the water supplying flow rate sensor 1225 is disposed in the water supplying device 122 and is configured to detect a flow rate of water supplied from the water supplying device 122 and generate a water supplying flow rate.

When the prompt information presented by the water supply prompter 14 to the operator indicates that the water supply device 122 needs to be connected to the first water tank 1525, the operator or the water supply switching valve set 19 communicates that the water supply device 122 needs to be connected to the first water tank 1525, and the water supply controller 121 can control the water supply flow of the water supply device 122 according to the water level of the first water tank, the water supply flow and the water spray flow, so that the water level of the first water tank is within the preset target water level range.

And, when the first water tank water level is higher than the preset target water level, the water supply controller 121 controls the water supply device 122 such that the water supply flow rate is lower than the water spray flow rate to lower the first water tank water level; and when the first water tank water level is lower than the preset target water level, the water supply controller 121 controls the water supply device 122 so that the water supply flow rate is higher than the water spray flow rate to raise the first water tank water level; when the first water tank water level is within the target water level range, the water supply controller 121 controls the water supply device 122 such that the water supply flow rate is equal to the water spray flow rate to maintain the first water tank water level.

Specifically, the water supply controller 121 controls the water supply device 122 to increase the water supply flow rate when the water level of the first water tank is 50% -80% of the preset target water level, and makes the water supply flow rate larger than the water spray flow rate when the water level of the first water tank is lower than 50%, so that the water level of the first water tank is raised to 50% -80% of the preset target water level, and the working stability of the water spray pump 1521 is improved.

When the water level of the first water tank is within 50% -80%, the water supply controller 121 controls the water supply flow of the water supply device 122 according to the water spraying state, and makes the water supply flow equal to the water spraying flow, in other words, the water supply device 122 increases with the increase of the water spraying flow of the water spraying pump 1521, and decreases with the decrease of the water spraying flow of the water spraying pump 1521, so that the water level of the first water tank is maintained at the preset target water level of 50% -80%, and the working stability of the water spraying pump 1521 is improved.

And when the water level of the first water tank is higher than 80%, the water supply controller 121 controls the water supply device 122 to reduce the water supply flow rate, and makes the water supply flow rate smaller than the water spray flow rate, so that the water level of the first water tank is reduced to a preset target water level of 50% -80%, and the working stability of the water spray pump 1521 is improved.

Further, when the water level of the first water tank is below 20%, the water spraying controller 151 controls the water spraying pump 1521 to reduce the water spraying flow by a certain value, and the water supply controller 121 also increases the water supply flow of the water supply device 122, and makes the water supply flow greater than the water spraying flow, so that the water level of the first water tank is raised to the preset target water level of 50% -80%, the water spraying pump 1521 is prevented from sucking air, and the working stability of the water spraying pump 1521 is improved.

Further, the water spraying status information further includes water spraying start-stop status information of the water spraying pump 1521, when the water supply prompter 14 indicates that the water supply device 122 needs to be connected to the first water tank 1525, the operator or the water supply change valve set 19 communicates the water supply device 122 with the first water tank 1525, the water supply controller 121 can control the water supply device 122 to start or stop according to the water spraying start-stop status information, for example, when the water spraying pump 1521 is started, the water supply controller 121 controls the water supply device 122 to start for a certain time delay so as to reduce jitter of the water supply device 122, and adapt to the situation that the water spraying pump 1521 sprays at a certain point, and similarly, when the water spraying pump 1521 stops spraying, the water supply controller 121 controls the water supply device 122 to stop for a certain time delay so as to reduce jitter of the water supply device 122.

The above-mentioned water supply mode corresponds to different water spraying modes of the water spraying device 152, for example, when the water supply device 122 is communicated with the water suction port 1522, the water supply device 122 directly supplies water to the water spraying pump 1521, also called relay water supply, and the water supplied by the water supply device 122 enters the water suction port 1522 of the water spraying pump 1521, is pressurized again by the water spraying pump 1521 and is sprayed, and because the water spraying flow and the range of the fire-fighting water spraying machine 15 can be effectively improved due to continuous pressurization of the two-stage or multi-stage pump. This spray mode requires precise flow real-time matching of the fire sprinkler 15 to the fire water supply 12 to avoid air or overload of the sprinkler pump 1521.

When the prompt information presented by the water supply prompter 14 to the operator characterizes the communication between the water supply device 122 and the water suction inlet 1522, the operator or the water supply change valve set 19 communicates the water supply device 122 with the water suction inlet 1522, and the water supply controller 121 can control the water supply device 122 so that the water supply flow is equal to the water spray flow, or so that the water supply flow follows the water spray flow to change, so as to improve the stability of the water spray pump 1521.

It should be noted that, when the water spray control command indicates that the water spray flow needs to be reduced, the water spray controller 151 controls the water spray pump 1521 to reduce the working power of the water spray pump 1521 so as to reduce the water spray flow, and the water supply controller 121 delays to reduce the water supply power of the water supply device 122 for a certain time, i.e. slightly reduces the water supply flow of the water supply device 122, and finally keeps the water supply flow consistent with the water supply flow, so as to reduce the shake of the water supply device 122.

In addition, when the water spray control command indicates that the water spray flow needs to be increased, the water supply controller 121 controls the water supply device 122 to increase the water supply power, and the water spray controller 151 controls the water spray pump 1521 to delay increasing the working power of the water spray pump 1521 for a certain time to slightly increase the water spray flow and finally keep the water supply flow consistent with the water supply flow, so that when the water spray commander needs to increase the water spray flow, the water supply device 122 is firstly enabled to increase the water spray power of the water supply flow at the lifting water spray pump 1521, so that the situation that the water spray pump 1521 is empty is avoided, and the stability of the water spray pump 1521 is improved.

Further, the water supply status information may further include a water supply pressure, the water spray status information may further include a water spray pressure, the fire water supply machine 12 further includes a water supply pressure sensor 1224, the water supply pressure sensor 1224 is disposed on the water supply device 122 and is configured to detect a pressure of the outlet water of the water supply device 122 and generate the water supply pressure, the fire water spray machine 15 further includes a water spray pressure sensor 1528, and the water spray pressure sensor 1528 is disposed on the water spray pump 1521 and is configured to detect a pressure of the spray water of the water spray pump 1521 and generate the water spray pressure.

When the prompt information displayed by the water supply prompter 14 to the operator indicates that the water supply device 122 is communicated with the water suction port 1522, the operator or the water supply change valve set 19 communicates the water supply device 122 with the water suction port 1522, the water supply controller 121 controls the water supply pressure of the water supply device 122 so that the water supply pressure is smaller than a first preset pressure, wherein the first preset pressure is a maximum pressure value allowed by the water spray port 1523 or an inlet of the water spray pump 1521, the water spray port 1523 may also refer to a water spray nozzle or the like, the water spray controller 151 controls the water spray pressure of the water spray device 152 so that the water spray pressure is smaller than a second preset pressure, the second preset pressure is an allowed maximum pressure value of the water spray port 1523 of the water spray pump 1521, so as to avoid the excessive pressure born by the water spray pump 1521 and ensure the normal operation of the water spray pump 1521.

The water supply mode corresponds to different water spraying modes of the water spraying device 152, for example, when the water supply device 122 is communicated with the water spraying port 1523, or when the water supply device 122 is communicated with the water spraying port 1523 of the fire-fighting water spraying machine 15, the water supply device 122 directly supplies water, the water spraying pump 1521 is not used for pressurizing, the pressurized water directly supplied by the fire-fighting water supply machine 12 directly accesses the water spraying port 1523 of the water spraying pump 1521 of the fire-fighting water spraying machine 15 for spraying, and the water spraying controller 151 is utilized to send a water spraying control command to the water supply controller 121 so as to control the water supply of the water supply device 122, so that the situations that the water supply flow rate of the water supply device 122 is too large or the pressure is too high, the start-stop control needs manual coordination, multiple command and the like are avoided.

When the prompt information presented by the water supply prompter 14 to the operator characterizes that the water supply device 122 is communicated with the water jet 1523, the operator or the water supply change valve set 19 communicates that the water supply device 122 needs to be communicated with the water jet 1523, and the water supply controller 121 controls the water supply device 122 according to the target water spray flow in the water spray control command so that the water spray flow is equal to the target water spray flow, thereby completing the effect of directly supplying water to the water jet 1523 of the water spray pump 1521 by the water supply device 122.
