The mode of difference realizes the perception to pressure, in the pressure or pressure differential range of setting, that is, can be considered valid data.Based on this,
For inductive switch 330 at least provided with two, the inductive switch 330 close to 100 runner of water meter body is starting meter
Shi Kaiguan 331, the inductive switch 330 far from 100 runner of water meter body are to terminate time switch 332.
This method still adopts the mode of duration representative information, the method for receiving data are as follows:
After step 1, starting time switch 331 detect signal, start timing, terminates time switch 332 and detect signal
Stop timing later, wherein time span is t5,
Continue to record follow-up data if time span t5 is the mark of the starting communication of the setting in communication protocol,
Terminate subsequent step if time span t5 is not the mark of the starting communication set in communication protocol.
After step 2, starting time switch 331 detect signal, start timing, terminates time switch 332 and detect signal
Stop timing later, wherein time span is t6,
The mapping relations of time span and control instruction according to specified in communication protocol, which solve, receives instruction, therefore can
Specific instruction is determined according to the t6 of different length.As represented within 1 second Open valve, valve is closed in representative in 2 seconds, and representative in 3 seconds uploads
Degree etc..
Step 3, based on the received control instruction control intellectual water meter
Correspondingly, the upper level control system of intellectual water meter, can increase pressure in initial time and reach starting timing
Detected value is switched, is remained above 20%~30% range of the pressure value of the position representative of starting time switch later
It is interior, less than in 30%~40% range for terminating the pressure value that time switch position represents, finally need to terminate time control
Pressing pressure is greater than in 20%~30% range for terminating the pressure value that time switch position represents, and avoids other to realize
Influence of the user with water to communication.
It preferably, is the method realizing water meter degree and intelligently uploading using the method that water meter sends the degree that water meter obtains
Are as follows:
Register or the not sent data information of variable are set, it includes multiple that not sent data information, which is an array,
Data.
Step 1, the time for uploading water meter degree for reaching setting the degree for needing the water meter sent are written not sent
Data information, in case sending.
Step 2 detects pressure change according to pressure detecting assembly 300, or is according to the judgement of the flowmeter of intellectual water meter
It is no to have water flowing, to judge whether tap is in open use water state, that is, judge whether to be in flowing water state.
If it is thening follow the steps 3, if otherwise repeating step 2.
Step 3 judges whether not sent data information is sky,
If being not sky, illustrates to have sent not yet, then read not sent data information, and execute step 4；
If it is sky, illustrates that data have been sent completely, then follow the steps 1.
Step 4, the method for sending the degree that water meter obtains according to water meter, send not sent data information；
Not sent data information is sent one by one, and judges whether water flow interrupts；
If do not interrupted, will continue to send not sent data information, and not sent data information is subtracted and has been sent out
