Technical Field

The invention relates to the technical field of remote monitoring of water meters, in particular to a direct-reading remote water meter and a control method thereof, which are used during line maintenance.

Background

At present, most water companies adopt a traditional manual meter reading mode. However, the method always has the problems of wrong reading, missing reading, inaccurate estimation, incapability of remotely transmitting data, incapability of monitoring data and the like. In order to solve the above problems, related solutions in the prior art can be generally divided into two types: the pulse type remote water meter and the direct-reading remote water meter.

The pulse type water meter is of photoelectric type, Hall type, reed pipe type, etc. The signals from the pulse type water meter are pulses, which are accumulated into data, which is the dial data. Because the finally obtained data is accumulated data, if a line is interrupted or a battery is powered off in the accumulation process, the accumulation is interrupted and data errors are caused, and the base number is reset after the data is restored again. A further problem with pulse type water meters is their poor ability to prevent magnetic interference.

The direct-reading remote water meter has photoelectric type and camera type, and its principle is that there are 5 pairs of light-emitting and receiving devices, and through reasonable arrangement and calculation, according to the difference of light source number received by reflecting surface and light-transmitting space, the position of sub-wheel can be determined. The photoelectric direct-reading remote water meter mainly solves the problems that the sensing positions on character wheels are quite accurate; and the other one is that the photoelectric direct-reading module is arranged in the mechanical watch, so that after the photoelectric direct-reading module works for a long time, partial tap water entering the character wheel box can cause the photoelectric module to lose effectiveness due to electric leakage and short circuit. The camera type direct-reading remote water meter is characterized in that a camera is arranged in front of a mechanical character wheel display window, a shot digital image is transmitted out, and then the digital image is processed to obtain the reading of the water meter. The processing mode needs to solve the technical problems of image processing, image transmission, decoding transmission and the like, not only is data processing difficult, but also has higher requirements on the surface cleanliness of the water meter, and therefore, the reliability is poorer.

This technical scheme is through laser emitter to pointer registration mark dish transmission laser signal, laser receiver can receive the laser signal that the pointer reflects back in the pointer registration mark dish, intervene laser emitter and laser receiver transmission signal through the different printing opacity district of seting up on the detection dish, laser emitter and the laser receiver that correspond with the pointer registration mark dish can detect different signal combination, the control unit converts the signal combination, can convert the binary code of signal combination into decimal digit, and then can obtain the numerical value that the pointer corresponds in the pointer registration mark dish.

Furthermore, the laser transmitter and the laser receiver vertically correspond to the pointer indication scale plate, and the detection scale plate and the pointer indication scale plate are obliquely arranged, so that a laser signal can be reflected out when the laser transmitter is shielded by the opaque region on the detection scale plate and cannot be received by the laser receiver; when the laser signal vertically projects to a pointer in the pointer indication scale plate, the laser signal can be directly reflected to a corresponding laser receiver and received by the laser receiver; if the laser signal of the laser transmitter passing through the light-transmitting area on the detection disc can vertically shoot to the pointer indication scale disc, when the laser signal is not projected to the pointer in the pointer indication scale disc, the laser signal can not be received by the corresponding laser receiver. Therefore, the indication position of the pointer in the pointer indication scale can be judged through the laser transmitter and the laser receiver.

Further, detect the dish and include central disc and radially outwards extend first ring, second ring and the third ring in proper order along central disc, the printing opacity district distributes on central disc, first ring, second ring and third ring, laser emitter and laser receiver set up and correspond from top to bottom with central disc, first ring, second ring and third ring respectively along the radial direction that detects the dish.
