Problems solved by technology

If the distance between each measurement point is 1 meter, if the traditional single-sensor illuminance meter is used for measurement, there will be a large number of measured points (generally, the average illuminance of the road surface between two lights needs to be measured about hundreds of points), data recording, and processing. The disadvantage of heavy workload, and the measurement of illuminance on roads that have been opened to traffic still has a large traffic safety hazard

Embodiment Construction

[0009] In the accompanying drawings of the description, the operational amplification modules (2, 8) are connected to the A / D conversion module (3) respectively, the A / D conversion module (3) is connected to the single-chip processing module (4), and the single-chip processing module (4) is connected to the single-chip processing module (4). The display module (5) is connected, and it is characterized in that two illuminance sensors (1, 7) are respectively connected with two operational amplification modules (2, 8), and a ruler (6) with a length of 1 meter is placed on the two illuminance sensors. Between the sensors (1, 7). The circuit elements except the two illuminance sensors are welded on the circuit board and placed in the casing, and a window is opened in a proper position of the casing, so that people can observe the display of the display module. Two illuminance sensors are fixed at both ends of a ruler with a length of 1 meter, and are connected to the circuit in the...

Abstract

The invention relates to a double-sensor illuminance meter belonging to the technical field of road illumination illuminance detection. A circuit is composed of illuminance sensors, operation amplifier modules, an A / D conversion module, a singlechip processing module, a display module and a ruler of which the length is 1 meter, wherein the two operation amplifier modules are respectively connected with the A / D conversion module which is connected with the singlechip processing module, and the singlechip processing module is connected with the display module. The invention is characterized in that two illuminance sensors are respectively connected with two operation amplifier modules, and the ruler of which the length is 1 meter is arranged between the two illuminance sensors. By the above technical scheme, the invention has the advantages and positive effects of high detection efficiency, small measuring error, small workload of data record and processing and high traffic safety factor.

Description

technical field [0001] The invention relates to a double-sensor illuminance meter, which belongs to the technical field of road lighting illuminance detection. Background technique [0002] Existing illuminance meters are all single-sensor illuminance meters, which are composed of a single illuminance sensor, an operational amplification module, an A / D conversion module, a single-chip processing module, and a display module. At present, in the domestic road lighting industry, the traditional single-sensor illuminance meter is used to detect the average illuminance and other data of the street lighting system by manual point-by-point measurement. One of the so-called manual point-by-point measurement methods is to divide the measurement section between two light poles into several equal-sized rectangular grids with a length and width of 1 meter, and set the measurement point at the center of the grid. If the distance between each measurement point is 1 meter, if the traditio...
