Multi-remote floor scale acquisition and recording method and system

Abstract

The invention relates to a multi-remote floor scale acquisition and recording method and a system, which belong to the technical field of information acquisition. The invention adopts a preemptive policy to periodically obtain production data and equipment states from a PLC, stores the production data and the equipment states, presets a weighing acquisition condition, an effective gross weight condition, an effective net weight condition and a permanent recording condition which respectively correspond to weight acquisition and recording action events, separates the acquisition action from the recording action, analyzes the obtained data according to the preset conditions to form an event queue with priority levels, and processes the events. The method can effectively solve the problem that data acquisition can fail because the permanent recording operation takes a long time when a plurality of floor scales share one upper computer, consequently, the configuration mode which configures an upper computer for each floor scale is avoided, and thereby the investment cost of upper computers is saved.

Description

technical field [0001] The invention belongs to the technical field of information collection, and specifically relates to a multi-remote weighbridge collection and recording method and system based on periodically updated data and using priority queues. Background technique [0002] In the domestic garbage, sludge or hazardous waste incineration treatment system, in addition to the calorific value of the incineration, its weight is also a key factor in determining the feeding time interval and controlling the temperature of the incineration treatment system, and is an important reference index for incineration process control. At the same time, the weight of incineration is also an important basis for cost accounting of waste disposal operation units. Therefore, how to accurately weigh and record the incineration materials is a key in the incineration control system. [0003] In the feeding mechanism of the bucket elevator, after the incineration material is manually loade...

AI Technical Summary

Problems solved by technology

Therefore, when recording the weighing information of a weighbridge, the weighing acquisition events of other weighbridges may not be processed by the host computer in a timely and effective manner, and the information has been updated when the record is completed and collected again, resulting in information failure;
