Abstract

The invention discloses a power carrier-based acquisition terminal, which relates to the field of instrument equipment management. The acquisition module is used to collect the current signal from the power line every preset cycle, generate an enable signal according to the circuit signal, and send it to the main control module; the main control module is used to control the AD in the current cycle when the enable signal is not received. The sampling module acquires the current value of the target device, and judges whether the current value exceeds the preset current value. If it exceeds, the metering module is controlled to measure the electrical parameters of the target device, and receives the timestamp of the current moment sent by the time keeping module. According to the electrical parameters and time Stamp generates a data packet, and controls the storage module to store the data packet. The collection terminal provided by the present invention improves the utilization efficiency of the target equipment, can solve the problem that the collection terminal cannot time the time in an offline signal environment, and completes the collection of instrument and equipment usage information, and improves the practicability.

Description

technical field [0001] The invention relates to the field of instrument equipment management, in particular to a power carrier-based acquisition terminal and method. Background technique [0002] At present, in the management process of instruments and equipment, in order to use the instruments and equipment efficiently and reasonably, it is necessary to record the use information of the instruments and equipment. In recent years, the use of power carrier technology to transmit information has high flexibility, and there is no need to build an independent channel. Applying power carrier technology to the statistical management of instruments and equipment can greatly reduce the transformation cost. [0003] However, the existing intelligent collection terminals using power carrier technology cannot time in an offline signal environment, and cannot complete the collection of equipment usage information. Contents of the invention [0004] The technical problem to be solved ...
