Cascade weight sorting system with delay measurement structure

Abstract

The invention relates to a cascade weight sorting system with a delay measurement structure. The system comprises a master station and a plurality of slave stations, the master station is connected with weight detection equipment, and the slave stations are connected with mechanical motion switches. The system is in a distributed architecture, the master station and the slave stations are communicated sequentially by means of series connection. Each slave station comprises a logic control unit, a data transceiving unit, a counting unit and a clock unit in sequential connection, wherein after the data transceiving unit receives data, the logic control unit performs ID matching and sends the data to the next slave station according to a matching result or executes mechanical actions and returns delay data generated by the counting unit and the clock unit to the master station. Compared with the prior art, the system has advantages that the slave stations are provided with the counting units and the clock units, delay data can be obtained, and accordingly delay parameter measurement can be realized when propagation delay is sent to a mainframe.

Description

technical field [0001] The invention relates to a weight sorting machine, in particular to a cascade weight sorting system with a delay measurement structure. Background technique [0002] The weight sorter is a mechanical device for grading and screening products by weight. It can screen products in different weight ranges to different assembly lines, saving money and time for manual operations. The mechanism of the current weight sorting machine adopts a single main controller for logic control, and a large number of IO ports are centrally controlled by the main machine, which greatly increases the complexity of the wiring work. At the same time, a large amount of power consumption is concentrated on the main machine. The reliability of the power supply system is very fatal, and at the same time, due to the large number of control IO ports of the host, the task of the host is very large, which requires the performance requirements of the MCU to be higher and higher, which ...

The mechanism of the current weight sorting machine adopts a single main controller for logic control, and a large number of IO ports are centrally controlled by the main machine, which greatly increases the complexity of the wiring work. At the same time, a large amount of power consumption is concentrated on the main machine. The reliability of the power supply system is very fatal. At the same time, due to the large number of control IO ports of the host, the task load of the host is very large, which requires the performance requirements of the MCU to be higher and higher, which greatly increases the difficulty and cost of system design.
