Abstract

A PC-based network integrated coal sample precision weighing system comprises: a host computer system, a communication network, and an executing mechanism. The host computer system includes a PC control unit, a data acquisition analysis and a feedback unit. The executing mechanism comprises a coal sample loading unit and a weight weighing unit. A communication network comprises an EtherCAT motioncontrol network and a Modbus weighing instrument communication unit. The PC-based network integrated coal sample precision weighing system realizes the accurate and rapid weighing and loading of the coal sample, improves weighing accuracy, realizes the coal sample loading with low error and high precision, and realizes an on-site weighing function by using the EtherCAT industrial Ethernet communication control, makes the weighing performance stable and reliable, provides real-time monitoring for the weighing process, realizes the information integration of the on-site weighing data, and lays afoundation for the later real-time monitoring, data optimization and testing process.

Description

technical field [0001] The invention relates to the field of coal sample preparation, in particular to a PC-based novel network-integrated coal sample precision weighing system and method, which uses the PC for motion control and data collection and analysis. Background technique [0002] At present, China's oil-scarce, gas-short, and coal-rich resource status determines that my country's energy structure will still be dominated by coal for a long time to come. However, during the utilization of coal resources, a series of problems such as resource destruction and environmental pollution have been caused. Therefore, how to strengthen the clean utilization of coal has become the top priority of the country's energy-saving and consumption-reducing work. Therefore, the quality of coal needs to be tested and analyzed before use, which is a process of sampling and analysis. After the sample is collected in accordance with the relevant standards, the next process is sample prepar...
