Description

Technical Field

[0001] The present invention relates to the technical field of communication detection, and more particularly to a communication unit disassembly, sorting and detection system. Background Art

[0002] A communication unit refers to a high-speed communication unit developed based on a high-speed carrier communication chip or a high-speed wireless communication chip for power line or wireless meter reading applications in an electricity consumption information collection system, which realizes the modulation, demodulation and data transmission and reception functions of data on power lines or wireless. The disassembled communication unit is a communication unit that is disassembled from the installation site due to quality and other reasons. These disassembled communication units need to be analyzed for faults and sorted by type through certain testing methods. Most fault problems can be reused after repair and detection. There is no system, fast detection system or solution for disassembled communication units, so it is difficult to locate fault problems in a unified manner. After the disassembled communication unit is returned to the factory, the operation and maintenance personnel often need to spend a lot of time on manual testing, or directly scrap it, resulting in a waste of manpower and material resources.

[0096] The power consumption unit contains a voltage and current acquisition circuit, uses the INA282AID circuit to detect the amplifier, and adds a current limiting circuit to protect the voltage and current acquisition circuit. Under the control of the main control module, within a certain period of time, the instantaneous voltage and instantaneous current on the communication unit access unit are sampled at equal intervals at a certain sampling frequency, and the product of the instantaneous voltage and current instantaneous values ​​is used as the instantaneous power of the communication unit to be tested.
