Based on the scheme, the Internet of things of the water meter 1 can be realized, the water consumption recorded by the water meter 1 can be timely synchronized to the cloud server 2, and the water consumption can be monitored on line; when a user does not pay water and wastes time based on the monitoring of the water consumption, a manager issues a water cut-off instruction through the server 2, and the control module 12 opens and closes the motor 11, so that the driving gear set 10 drives the valve 9 to be closed and closed in place, the remote water cut-off function is realized, namely, the remote switch control function is realized, and one-to-one accurate opening and closing of a certain water valve can be realized;

secondly, the water consumption measured by the meter head 4 is synchronized in real time to the water consumption module 5 to be stored, and is uploaded to the server 2 at the background after a preset uploading time interval, so that the bandwidth and the calculation pressure of the server 2 can be greatly reduced, the water meter 1 is also powered by a battery, part of the power consumption can be saved through the timing trigger design of the clock module 7, the service time of a power supply is prolonged, and the whole system is coordinately optimized.

When the water meter 1 is started for the first time, the preset uploading time interval for sending the water consumption by the first clock module 7 and the first communication module 6 needs to be set at regular time. And sending a frequency modulation instruction to a first communication module 6 of the water meter 1 through the server 2. After the frequency conversion module 8 receives the frequency modulation instruction sent by the server 2 through the first communication module 6, the preset uploading time interval of the uploading water consumption of the first communication module 6 is triggered by the clock module 7 at regular time and is adjusted to the interval specified by the frequency modulation instruction. Subsequently, when the water meter 1 runs, the water meter can be triggered once every preset uploading time interval, the communication module I6 reads the water consumption in the water consumption module 5, and the water consumption in the water consumption module 5 is transmitted to the server 2.

In addition, in subsequent operation and maintenance, a good balance adjusting window is arranged between the detection timeliness and the energy conservation of the water consumption, when adjustment is needed, the server 2 can remotely send a frequency modulation instruction to the frequency conversion module 8, the frequency of the communication module I6 for sending the water consumption at fixed time is changed, and when corresponding adjustment requirements exist, the sending frequency can be conveniently modified. And the interval I and the interval II below can also be transmitted through the server 2 to issue an instruction and the communication module I6 to finish the issuing of a modification instruction, so that the adjustment and the modification in the later period can be realized.

When the frequency conversion module 8 detects that the added value of the water consumption recorded by the water consumption module 5 in unit time exceeds a preset upper limit threshold value, the clock module 7 regularly triggers the preset uploading time interval of the water consumption of the communication module I6 to be rewritten from a first interval to a second interval with shorter time interval;

when the frequency conversion module 8 detects that the added value of the water consumption recorded by the water consumption module 5 in unit time is lower than a preset lower limit threshold value, the clock module 7 regularly triggers the preset uploading time interval of the water consumption uploaded by the communication module I6 to be rewritten from the interval two to the interval I with a longer time interval.

In order to save energy and measure water consumption more accurately. When the water is not used much, the frequency conversion module 8 adjusts the trigger frequency of the clock module 7 to the interval I with longer interval time, so that the frequency of sending the water consumption to the server 2 by the communication module I6 is lower, the energy-saving effect is achieved, the bandwidth and the calculation pressure of the server 2 are reduced, and the resources are saved; when a large amount of water is used, the change of the water consumption is quick in a short time, the data needs to be updated more timely, the frequency conversion module 8 is triggered to switch the clock module 7 to be the preset uploading time interval of the interval two in time to trigger the communication module I6 to upload and update the data more timely, and the hardware performance of the server 2 is increased endlessly and singly along with the increase of users and the water meters 1 in the past. The resource allocation is more reasonable.

The storage module 22 of the server 2 stores the opening and closing states of the valve 9 of the header 4 corresponding to each user account and the instruction sending record of the server 2;

after the processing module 24 of the server 2 controls the communication module II 23 to send a water stopping instruction to the communication module I6, the processing module 24 changes the opening and closing state of the valve 9 stored in the storage module 22 corresponding to the user account number into a closing state;

after the processing module 24 of the server 2 controls the communication module II 23 to send a water starting instruction to the communication module I6, the processing module 24 changes the opening and closing state of the valve 9 stored in the storage module 22 corresponding to the user account number into an opening state;

after the user terminal 3 logs in the server 2 by using the user account, the opening and closing state and the water consumption of the valve 9 stored in the storage module 22 are read in real time through the communication module II 23 in communication connection with the user terminal;

when the water consumption increment under the corresponding user account in unit time exceeds a preset early warning threshold value, the server 2 sends an excessive water consumption early warning message to the user terminal 3 through the second communication module 23;

when the user terminal 3 sends a valve closing instruction to the second communication module 23 of the server 2, the server 2 sends a water stopping instruction to the first communication module 6;

when the user terminal 3 sends a valve opening instruction to the second communication module 23 of the server 2, the processing module 24 searches the storage module 22 for an instruction sending record of the header 4 corresponding to the user account,

when the latest instruction sending record is not the water stopping instruction sent by the server 2, the server 2 sends a water starting instruction to the communication module I6,

when the latest instruction transmission record is the water-stopping instruction transmitted by the server 2 itself, the server 2 transmits a water-stopping notification to the user terminal 3.

The above-mentioned interactive scheme between the user terminal 3 and the server 2 is to deal with the anticipation of emergency situations and the modification and innovation of the user's daily convenient operation. After the water consumption exceeds the early warning threshold value in unit time, the situation that a tap is probably forgotten to be turned off or a water pipe is broken possibly occurs, the user terminal 3 can conveniently know the water using close condition and the valve opening and closing state of the water meter 1 by logging in the server 2 by sending the excessive water warning information to the user terminal 3, the user terminal 3 can transmit a valve closing instruction to the server 2 and then turn a water stopping instruction to the water meter 1 through the server 2, and the water valve is turned off in time, so that the functions of reminding and remotely closing the valve to stop water in the emergency situation are achieved; when the water valve needs to be opened again, a valve opening instruction is sent to the server 2 through the user terminal 3, and then the water instruction can be started in the direction of the server 2, so that remote opening is realized; in the step of opening the valve, if the user terminal 3 detects that the latest instruction sending record is a valve closing instruction sent by the server 2 independently, the water cut-off operation of the management party is corresponded, and the user cannot open the valve by himself, which is a limitation on the authority, and generally, after the user finishes paying the water fee, the management party opens the water valve again.
