Gauge remote digital image acquisition device

Abstract

The invention discloses a gauge remote digital image acquisition device which comprises a camera and a reflecting mirror. The camera is located out of a digital reading area of a gauge counter, and the reflecting mirror reflects images from the gauge counter to the camera. The gauge remote digital image acquisition device uses the reflecting mirror to reflect the images from the gauge counter to the camera, enables a light path between the gauge counter and the camera to be lengthened, accordingly still can acquire digital images of the gauge counter even if the camera deviates from the digital reading area, prevents manual meter reading from being shielded due to existing of the camera, and furthermore can accurately and clearly obtain images due to the facts that the light path is lengthened in a limited size, and accordingly the wide angle and the focal distance of the camera can both be effectively adjusted. The gauge remote digital image acquisition device is simple and reliable in structure, has miniaturization and modularization design, and can be widely used in a remote automatic meter reading system and other systems which need to obtain the images remotely.

Description

technical field [0001] The invention relates to an image acquisition device in a remote automatic meter reading system. Background technique [0002] The remote automatic meter reading system is gradually replacing the traditional manual door-to-door reading and meter reading methods. The staff only need to be in the central control room to know the readings of the remote user's meter in real time and accurately. [0003] In order to realize remote automatic meter reading for mechanical metering instruments, the problem of converting mechanical signals into electronic signals must be solved first. The pulse counting method used in the early stage has been eliminated; the sampling method using photoelectric direct reading technology also has certain limitations. First, it needs to modify the counter wheel of the meter; second, it must go to the On-site verification, in addition, the modification of the meter in use will be a very difficult or even impossible work. The camer...
