Description
技术领域technical field
本发明涉及实验基地管理技术领域，具体涉及一种集净化与监控于一体的实验基地管理平台。The invention relates to the technical field of experimental base management, in particular to an experimental base management platform integrating purification and monitoring.
背景技术Background technique
工科类院校的实验基地，主要是以精密机床、精密工量器具、计算机机房、电工电子设备、工业机器人等为主。由于设备的特殊性，要求室内保持恒温、干燥、去除有害气体，以确保机器、工量器具的完好，从而达到精密加工、精密测量误差小。因为环境温度的变化会引起设备(金属材料)的热胀冷缩，湿度过大会引起机床、工量器具的锈蚀以及电子元件电阻值的变化。加工时产生的切削热会产生有害气体，而加切削液切削加工有害气体则更甚。目前，由于实验基地的监控***与净化***是独立工作的，由于监控与净化未能一体化管理，在监控中心不能实时了解实验室内空气情况，实验过程中往往会导致机床故障、精度不达标，测量工量器具不能正常使用、测量数据不准确等。不仅造成学校资源的损失，而且严重影响正常教学。The experimental bases of engineering colleges and universities mainly focus on precision machine tools, precision measuring instruments, computer rooms, electrical and electronic equipment, and industrial robots. Due to the particularity of the equipment, it is required to maintain a constant temperature, dry, and remove harmful gases indoors to ensure the integrity of the machines and measuring instruments, so as to achieve precision machining and small precision measurement errors. Because changes in ambient temperature will cause thermal expansion and contraction of equipment (metal materials), excessive humidity will cause corrosion of machine tools and measuring instruments and changes in the resistance value of electronic components. The cutting heat generated during processing will produce harmful gases, and the harmful gases will be even worse when cutting with cutting fluid. At present, because the monitoring system and the purification system of the experimental base work independently, and because the monitoring and purification are not managed in an integrated manner, the air conditions in the laboratory cannot be understood in real time in the monitoring center, which often leads to machine tool failures and substandard precision during the experiment , Measuring instruments cannot be used normally, measurement data is inaccurate, etc. It not only causes the loss of school resources, but also seriously affects normal teaching.
