Embodiment

[0008] In the optical path of the sensor ( figure 1 ) are provided with two charge-coupled device linear array integrated circuits 1 and 2 (the number of charge-coupled device linear arrays is required by the measurement range of the vertical coordinate), and the two charge-coupled device linear array integrated circuits 1 and 2 are perpendicular to each other Arranged, LED light-emitting diode arrays 3, 4, and 5 are arranged on the opposite sides of the two charge-coupled device linear array integrated circuits 1, 2. In the middle of integrated circuits 1 and 2, 6 is a glowing LED light-emitting tube, which serves as a point light source to illuminate the opposite charge-coupled device array, and produces a projection 7 on the surface of the charge-coupled device array due to the shading of the vertical line cross-section .

[0009] In the sensor circuit ( figure 2 ), the LED drive circuit 9 and the charge-coupled device line array drive circuit 10 correspondingly arranged...

Abstract

The invention is a kind of optical coordinate apparatus which has remote maintaining function. The connection between the sensor light path and the sensor circuit is realized through connecting the charge coupler array and LED illuminant diode array in the sensor light path and the relative charge coupler array driving circuit and LED illuminant diode array driving circuit in the sensor circuit, the charge coupler array in the sensor light path is connected with the signal processing and project collecting circuit in the sensor circuit; there sets a measuring range for the sensor light path, one side of it sets a charge coupler array, the other side sets a LED illuminant diode array; the sensor circuit has a driving circuit and a microprocessor, signal processing and project collecting circuit, a network communication model for providing remote test analysis and diagnosis functions. The measured data has a big redundancy; the invention carries on analysis, diagnosis, and maintenances according to the sensor data, and upgrades the reliability working in mal-condition.

Description

technical field [0001] The invention relates to an optical coordinate instrument with a remote maintenance function for dam safety monitoring, which can remotely detect the working status of the instrument, diagnose the measurement data based on the redundant characteristics of the sensor, and timely maintain hidden dangers. Ensure that the instrument can work reliably for a long time in harsh environments. It belongs to the technical field of monitoring optical instruments. Background technique [0002] At present, all kinds of vertical coordinate instruments used for dam safety monitoring are composed of corresponding displacement sensing devices, related measurement circuits, communication modules and recording equipment. Among them, the displacement sensor is the key, which converts the tiny vertical displacement into electrical quantity for automatic measurement by subsequent instruments. Compared with other types of displacement sensors, optical displacement sensors ...
