specific Embodiment approach 1
[0021] Specific implementation mode one: see figure 1 This embodiment will be described. The three-time sampling water volume data collector described in this embodiment includes an interrupt source identification and reset circuit 1, a single-chip microcomputer 2, a counter 3, a magnetically controlled water meter sensor 4, a serial port communication circuit 5, a clock 6, and a memory 7. The interrupt source identification And the interrupt reset signal output end of reset circuit 1 is connected with the interrupt reset signal input end of single-chip microcomputer 2, and the control signal output end of described single-chip microcomputer 2 is connected with the control signal input end of counter 3, and the data signal output end of described counter 3 is connected with The data signal input end of the single-chip microcomputer 2 is connected, the pulse signal output end of the magnetically controlled water meter sensor 4 is connected with the pulse signal input end of the...
specific Embodiment approach 2
[0024] Specific implementation mode two: see figure 2 with image 3 This embodiment will be described.
[0025] The concrete steps of this embodiment are:
[0026] Step 1, when the time reaches the sampling interval point, the interrupt source identification and reset circuit 1 receives the clock signal sent by the clock 6, and the interrupt source identification and reset circuit 1 sends an interrupt signal to the single-chip microcomputer 2, and now the single-chip microcomputer 2 starts to read Get the state that the magnetically controlled water meter sensor 4 sends pulses;
[0027] Step 2, the single-chip microcomputer 2 judges whether the pulse described in step 1 is in a high level state, if yes, then perform step 3; no, then perform step 4;
[0028] Step 3, the single-chip microcomputer 2 reads the data in the counter 3, and sends the data into the memory 7, and then the single-chip microcomputer 2 sends a control command to the counter 3 to clear the data in the c...
specific Embodiment approach 3
[0036] Specific implementation mode three: see Figure 4 This embodiment will be described. The difference between this embodiment and specific embodiment 1 is that the magnetically controlled water meter sensor 4 in this embodiment adopts the magnetically controlled water meter sensor produced by Weifang Weiwei Technology Co., Ltd.
[0037] Described magnetron water meter sensor 4 is made up of pulse emission device, resistance 4-3 and electric capacity 4-4, and one end of resistance 4-3 is connected with 3.0V power supply, and the other end of resistance 4-3 is connected with the pulse emission device simultaneously. One end is connected to the positive pole of the capacitor 4-4, which is the pulse signal output end of the magnetron water meter sensor 4, and the other end of the pulse transmitting device is grounded simultaneously with the negative pole of the capacitor 4-4.
[0038]The pulse transmitting device is composed of a reed switch 4-2 and a magnetic needle 4-1. Th...
