1.计量方式及性能要求稳定土厂拌站的电子计量系统可以采用仪表、工控机和PLC(可编程控制器)3种控制方式。由于现阶段用PLC对模拟量的控制在实际应用中效果不是很理想,所以现在电子动态计量稳定土厂拌设备的控制系统多数采
1. Measurement methods and performance requirements Stability Soil mixing plant electronic metering system can be instrumentation, industrial computer and PLC (programmable logic controller) 3 kinds of control methods. Because at this stage with the PLC analog control in the practical application of the effect is not very satisfactory, so now electronic dynamic measurement of soil mixing plant control equipment most mining
