technical field [0001] The invention belongs to the field of optical testing, and in particular relates to a distribution photometer system which reduces wiring, reduces signal interference and signal loss, and improves the reliability of control and measurement. Background technique [0002] The goniophotometer is mainly used to measure the luminosity of the measured light source at various angles in space. It is an instrument integrating optical, mechanical and electrical technologies. [0003] There are various types of goniophotometers. The mechanical part mainly includes optical radiation measuring instruments and a rotating table for clamping the measured light source and making the measured light source and the optical radiation measuring instrument sampling device (such as photometric probe) relatively rotate. The relative rotation between the measured light source and the sampling device of the optical radiation measuring instrument is realized by the rotation of th...

[0008] The present invention mainly solves the problem that a large number of long wires are directly connected to the control center of the existing goniophotometer system, which easily causes signal loss and interference on the wires, resulting in low reliability and real-time performance of the entire goniophotometer system and poor angle control accuracy. And photometric measurement accuracy is affected and the management and maintenance of the system are more complicated technical problems, and solve the technical problems of wire connection in the distribution photometer to avoid winding and strain during rotation; provide a high transmission performance that makes full use of the digital signal channel And strong anti-interference ability, effectively improve system reliability and real-time performance, ensure photometric measurement accuracy and angle control accuracy of the goniophotometer system

[0009] The invention also solves the problem that the existing goniophotometer system has long and many wires and is prone to entanglement, so that the rotating parts need to take limiting measures, which affects the measurement and sampling, and long-term operation is likely to cause strain on the wires and even bring safety. Hidden technical problems; provide a goniophotometer system that reduces the number of connecting wires, improves the wiring of the wires, makes the wires less prone to entanglement, thus does not affect the measurement and sampling, reduces damage to the wires, prolongs the service life of the wires, and ensures safety
