Camera shooting direct reading remote water meter device

Abstract

The invention relates to a camera shooting direct reading remote water meter device which comprises a mechanical water meter, a transparent plastic cover, an optical reflective lens, a camera lens, a light supplementing light source, a signal processing unit, a communication unit and a PCB. The camera lens, the light supplementing light source, the signal processing unit and the communication unit are installed on the PCB, a character code disc of the mechanical water meter is covered with the transparent plastic cover, the optical reflective lens is installed on the reverse side of a top plate of the transparent plastic cover, the PCB is installed on the inner side face of the transparent plastic cover, and the camera lens is connected with the signal processing unit which is connected with the communication unit. The device is small in data transmission quantity, high in transmission speed and data collection efficiency, small in size and attractive in appearance.

Description

technical field [0001] The invention relates to a camera remote transmission water meter. Specifically relates to a camera direct reading remote water meter device. Background technique [0002] At present, the whole country is adopting the scheme of camera direct reading technology, which is to transmit the picture of the code disc of ordinary mechanical water meter taken by the camera without processing or after simple compression processing to the computer through the communication unit, and finally the computer completes the recognition processing of the picture. Obtain the digital content displayed on the code disc. However, due to the need to transmit pictures in this way, the amount of transmitted data is large, so the transmission speed is slow, the time required for transmission is long, and the efficiency of data collection is low. In addition, in the remote water meters that currently use camera direct reading technology, the camera is fixed directly above the c...

Problems solved by technology

However, this method needs to transmit pictures and transmit a large amount of data, so the transmission speed is slow, the transmission takes a long time, and the efficiency of data collection is low.

In addition, in the remote water meters that currently use camera direct reading technology, the camera is fixed directly above the code plate of ordinary mechanical water meters. In order to obtain a complete image of the code plate, the distance between the camera and the code plate must be greater than 55mm, so it will The height direction of the appearance of the product is too large, which affects the appearance of the product
