一种料仓控制系统

Stock bin control system

Abstract

The invention relates to a stock bin control system, which comprises a weighting sensor, a programmable controller and a display instrument. The weighting sensor is arranged under a supporting seat of the stock bin, the programmable controller is respectively connected with the weighting sensor and the display instrument through a shielded cable, and a standard 4-20mA signal transmission is adopted for the weighting sensor, the programmable controller and the display instrument. The weighting sensor is generally set with 3-4 points. The stock bin control system is characterized by indirectly measuring the material level of the material stock in the stock bin by means of weighing, and calculating the material flow rate through the weight change to accurately determine the condition of the material discharge and jamming. The invention has the advantages that: the method of weighing is adopted to directly measure the material level of the material stock in the stock bin and the material flow rate is calculated through the weight change to accurately determine the condition of the material discharge and jamming, thereby solving the problems of easy damage and failure of the contact charge level indicator and the non-contact charge level indicator and the infidelity of the measured result, and particularly solving the problem of detection of jamming in the discharge port.
本发明涉及一种料仓控制系统,包括称重传感器、可编程控制器、显示仪表,称重传感器设置在料仓支座下,可编程控制器分别通过屏蔽电缆与称重传感器、显示仪表相连,称重传感器、可编程控制器、显示仪表之间采用标准4~20mA信号传输。所述称重传感器一般设置3~4点。所述的一种料仓控制系统,其特征在于,通过采用称重方式间接的测算料仓存料料位,并通过重量的变化计算料流速度以准确判断卸料堵塞情况。本发明的有益效果是:通过采用称重方式间接的测算料仓存料料位,并通过重量的变化计算料流速度以准确判断卸料堵塞情况,解决了现有技术中接触式或非接触式料位计容易损坏失效和测量结果失真的问题,尤其是解决了卸料口堵塞的检测难题。
