Description
Technical Field
The invention relates to the technical field of measurement, in particular to a real-time water consumption data acquisition method and a terminal.
Background
A typical conventional rotary wing water meter dial typically includes a rotary pointer indication and a digital code display. Therefore, calculating the number of turns of the indicating pointer or the number displayed by the identification code meter is a scheme used for remote meter reading of a typical common rotary wing type water meter.
On one hand, the reed switch can be opened and closed under the action of the magnetic pointer, and a pulse signal is formed under the coordination of an external circuit. When the pointer on the dial of the common rotary-wing water meter is replaced by a magnetic pointer, the number of rotation turns of the magnetic pointer is in proportion to the water consumption, so that the number of pulses formed by the reed switch collected by the MCU can reflect the water metering amount of the water meter in real time. However, due to the specific 'water hammer' effect of tap water, the pointer of the water meter swings clockwise and anticlockwise, the phenomenon can cause the 'opening and closing' misoperation of the reed switch, and the accuracy of pulse acquisition of the reed switch still has problems in the actual acquisition process.
On the other hand, by using the photographic technology to obtain the dial image and identifying the water consumption number in the dial image, more accurate water quantity metering can be obtained. In a non-real-time environment, accurate metering data can be satisfactorily obtained by taking a picture once a day or a month. However, in a real-time environment where continuous startup shooting or frequent snapshot is required, the energy consumption caused by the camera system causes energy pressure that is difficult to bear for the water meter collector powered by the battery.

Referring to fig. 1 to fig. 3, a first embodiment of the present invention is:
a real-time water use data acquisition method comprises the following steps:
s1, scanning a reed switch;
in step S1 of the present embodiment, the dual reed pipe assembly and the timer are scanned simultaneously. As shown in fig. 2, the double reed pipe assembly includes a first reed pipe and a second reed pipe that are perpendicular to each other, the first reed pipe and the second reed pipe are sequentially located on a rotation path where a magnetic pointer rotates clockwise, and the double reed pipe assembly and the magnetic pointer in step S1 are installed on a scale of 0.01 cubic meter, where the first reed pipe and the second reed pipe are connected to the processor through a pulse interface.

as shown in fig. 3, step S2 in this embodiment is specifically as follows:
judging whether the timing time of the timer reaches the preset photographing time, if so, executing the step S3;
if not, judging whether any reed pipe in the double-reed pipe assembly generates pulse, if so, judging whether the generated pulse can form effective pulse turns, if so, performing accumulation calculation on the effective pulse turns, wherein the effective pulse turns refer to that the magnetic pointer sequentially triggers the first reed pipe and the second reed pipe in the clockwise rotation process and triggers the first reed pipe again, and the time from triggering the first reed pipe to triggering the second reed pipe is less than the time from triggering the second reed pipe to triggering the first reed pipe again;
if none of the reed switches in the dual reed switch assembly generates a pulse, or the generated pulse cannot form a valid number of pulse turns, returning to step S1;
judging whether the number of effective pulse turns of the reed pipe is greater than 10, if so, saving decimal point data of water consumption, otherwise, returning to the step S1;
and judging whether the number of effective pulse turns of the reed switch is more than 100, if so, refreshing decimal point data of water consumption, and then executing the step S3, otherwise, returning to the step S1.
And judging whether the reed switch is in a pulse stop state, if so, executing a step S3, otherwise, returning to the step of judging whether the generated pulse can form effective pulse turns.
Otherwise, judging whether the pulse accumulated number of the reed switch reaches the preset pulse number, if so, executing the step S3, otherwise, returning to the step S1.
And S3, recording the current time, and starting the camera to take a picture to obtain real-time water consumption data.
The double reed pipe assembly and the magnetic pointer are arranged on a scale of 0.01 cubic meter, 10 circles are 0.1 ton, 100 circles are measured to be 1 ton, namely, the integral digits of the code table jump once when the double reed pipe assembly and the magnetic pointer rotate clockwise by 100 circles, so that the camera can shoot and recognize at least on the premise of one ton of water consumption.
Referring to fig. 2, there are generally four cases:
(1) and under the normal condition, the magnetic pointer rotates clockwise, triggers first tongue tube, second tongue tube in proper order and triggers first tongue tube again to form the effectual effective water metering of round.
(2) When the tiny water hammer effect causes misoperation, the magnetic pointer only spans the first reed pipe, and then swings under the first reed pipe or the second reed pipe, so that the magnetic pointer only causes the misoperation of opening and closing the first reed pipe or the second reed pipe, and a circle of effective water metering cannot be formed.
(3) When the 'water hammer' with large effect causes malfunction, the magnetic pointer sequentially spans the first reed pipe and the second reed pipe in the swinging process and returns to swing through the second reed pipe and the first reed pipe, and a circle of effective water metering cannot be formed.
(4) When the magnetic pointer swings in the non-reed pipe area due to the water hammer effect, no pulse signal is generated, and a circle of effective water metering cannot be formed.
Therefore, the false action caused by the water hammer effect cannot form a circle of effective water metering, so that the false action caused by the water hammer effect can be effectively overcome through the number of effective pulse circles, the acquisition error is effectively reduced, and the accuracy of water metering is improved.
Referring to fig. 4, a second embodiment of the present invention is:
