Problems solved by technology
[0003] The difficulties of manual detection of light intensity distribution are: first, there are many measurement points and a large workload, which requires professional operation; second, the hand-held instrument or probe is detected at a specific position, and its horizontal and vertical positioning have large errors, which is easy to cause detection problems. Human errors in the process; third, the detection time is long, the sensor needs to be calibrated every day and the lamps are preheated in advance, whether the calibration is still to be confirmed in the actual situation, and the detection system error cannot be avoided; the fourth is the process of data recording, processing and transfer It is easy to make mistakes; Fifth, some indicators are calculated manually, which is easy to lose part of the accuracy

The invention belongs to the technical field of automatic instruments and meters, and particularly relates to an illumination uniformity detection device for a plant growth lamp. The device comprisesa lamp holder 1 used for installing the lamp, a three-axis driven mobile platform 3 with an illumination sensor 2, a light intensity sensor installed on the mobile platform and a PC 4. Before detection, the plant growth lamp needs to be installed on the lamp holder and turned on to operate to a stable state; the PC controls three stepping motors to enable the light intensity sensor to scan point by point in a three-dimensional space, one point measures one piece of light intensity data, and the computer generates a light intensity distribution diagram according to the three-dimensional coordinates and the detection data, so that the illumination uniformity index of the plant cultivation surface is calculated. The device can effectively collect the illumination intensity of the plant cultivation surface, improves the detection efficiency and detection precision, avoids human errors and system errors, and avoids errors in data transmission and calculation processes.
Description
technical field [0001] The invention belongs to the technical field of automatic instruments and meters, and relates to technologies such as light environment characteristic detection of lamps, data collection and data processing, and in particular to a device for detecting illumination uniformity of plant growth lamps. Background technique [0002] Illumination intensity and illumination uniformity indicators are important indicators for plant growth lamps and special agricultural lamps. At present, manual measurement is mainly performed point by point, and the measurement results are input into special applications or software to generate light intensity distribution maps manually or automatically. Now In the prior art, special measurement tools or software have not been used for the illumination uniformity index. The measurement of light intensity distribution requires a lot of manual operations, multiple software, and even manual analysis, which is time-consuming, heavy w...
