37、。因此，要用自动化技术促进水位检测与控制自动化的发展。1.2 水位检测系统设计的意义水位检测系统是自然界和一般工业界不可缺少的一种检测系统。但凡江河湖海，工业中应用的蓄水池、水塔、水箱、地下水等都需要有水位检测。供水系统中有许多设备由于所处地势高，上下极为不便，有时水即将用完或者已经用完也不知道，造成需用水时却水量不足或者无水可用的情况。此时，在向池中注入水过程中，由于不知道水位情况，也就无法控制水量多少，为了准确掌握水位情况，传统的做法是安排人员进行人为监控，这样不仅会占用人力、物力，还会大大影响工作效率。为此需要对水位监测情况实现自动化监测、数据化、智能化显示、视觉或听觉冲击化报警，实现水
38、位检测一个完整的系统，那么工作人员便可以在操作室获知整个设备的水位状况，如此不但大大减低工作人员的危险性，同时更提高了工作效率及简便性。1.3 本设计研究的内容和方法内容：本设计以MCS-51 系列单片机为核心设计水位检测系统，自行设计电源，选用液位检测传感器检测液位，数码管显示，当液位高度太高或太低时，报警（可采用中断方式设计），由单片机控制继电器的闭合来控制水泵的工作，达到调节水位的效果。方法：本设计经过调研，收集且分析相关技术资料，综合考虑液位检测技术发展和液位检测系文档编码:CP3M4F6K5E9 HA6L10C1Z10W9 ZK9L10C7C10T10文档编码:CP3M4F6K5E9
