Description of drawings
Fig. 1 is the structural representation of a kind of electronic intelligence water meter of the utility model;
Fig. 2 is the circuit theory diagrams of electronic intelligence water meter shown in Figure 1.
Embodiment
Below in conjunction with accompanying drawing the utility model is elaborated:
Like Fig. 1, shown in Figure 2, among the figure: 1, water meter case, 2, the metering impeller, 3, carrier gear; 4, magnet ring, 5, base plate, 6, Magnetic Sensor, 7, electronic module; 8, OLED display screen, 9, switch, 10, resistance, 11, control circuit; 12, driving circuit, 13, the driving circuit power switch, 14, photoelectric sensor.
It comprises display screen; Also comprise the single-chip microcomputer that is connected with this display screen; This single-chip microcomputer comprises a voltage monitoring interface; When the voltage of this voltage monitoring interface during saltus step, correspondingly produces this display screen power supply of control signal control between high level and low level, said single-chip microcomputer also connects photoelectric sensor.
Also comprise switch and resistance, this switch one termination is gone into voltage, and the other end connects the voltage monitoring interface I ∕ O1 of this resistance and this single-chip microcomputer; This resistance one end is connected to this I ∕ O1, other end ground connection; This single-chip microcomputer also comprises driving circuit, and this single-chip microcomputer is connected with this display screen through this driving circuit; This driving circuit is used to drive this display screen; This driving circuit power switch also connects the I ∕ O2 of single-chip microcomputer; Driving circuit connects the I ∕ O3 of single-chip microcomputer; Photoelectric sensor connects the I ∕ O4 of single-chip microcomputer; This display screen is the OLED display screen; When the voltage of I ∕ O1 is high level during to low transition, this single-chip microcomputer produces control signal to be stopped to this drive circuitry; When the voltage of I ∕ O1 is low level during to the high level saltus step, this single-chip microcomputer produces control signal to begin to this drive circuitry; When this switch conduction, the voltage of I ∕ O1 is high level; When this switch broke off, the voltage of I ∕ O1 was low level.
When the water meter rotation begins to measure; Because it is (this is determined by the water meter self character) of fixing that pointer rotates the water yield (also being pulse equivalency) of a circle representative; Carry out the extracting of time simultaneously through single-chip microcomputer, because the response time of single-chip microcomputer is 1.28 * 10
-7Second, can ignore fully, can in a recurrence interval, draw the water meter instantaneous delivery like this, compare with the flow of standard again, can draw the instantaneous delivery relative error of water meter.Because on some test points, the time of use is consistent, so the instantaneous delivery relative error is equal to the water meter relative error.The error amount of this water meter can calculated in a flash like this.
