监测系统首先通过安装时按照规划位置预先对地址编码电路进行设置(0-254)，这样就确定了每个信息处理单元的编码，压力传感器将采集信号传输给信息处理单元中的信号处理电路，经信号处理电路将压力传感器采集到的模拟信号转化为标准采样电压范围内的数字信号，满足A/D接口电路采集量程范围精度即A/D接口电路的标准参考电压是4.096V，也就是要把压力传感器采集到的模拟信号，变换到A/D接口电路的0-4.096V的范围内，保证AD数学化精度，单片机接收A/D接口电路的数字信号后，再通过驱动接口传输至WIFI模块，经信息集中单元发送至远程控制单元进行分析与管理，便于管理人员远程对滤袋压力状态数据等信息进行综合分析，并决定下一步操作与管理；当远程控制单元监测分析到生产过程中出现滤袋压力过载等紧急情况，通过紧急手动除尘开关模块装置，通过网络接口传输回信息集中单元的服务器，服务器根据传输来的地址信息解析出具体的信息处理单元，通过输出接口电路输出紧急控制信号，控制PLC手动除尘处理，有效地实现除尘监测。The monitoring system first pre-sets the address coding circuit (0-254) according to the planned position during installation, so that the code of each information processing unit is determined, and the pressure sensor transmits the collected signal to the signal processing circuit in the information processing unit. The analog signal collected by the pressure sensor is converted into a digital signal within the standard sampling voltage range by the signal processing circuit, which satisfies the accuracy of the acquisition range of the A/D interface circuit, that is, the standard reference voltage of the A/D interface circuit is 4.096V, which means The analog signal collected by the pressure sensor is converted into the range of 0-4.096V of the A/D interface circuit to ensure the mathematical accuracy of AD. After the microcontroller receives the digital signal of the A/D interface circuit, it is transmitted to the WIFI through the drive interface. The module is sent to the remote control unit for analysis and management through the information centralization unit, which is convenient for the management personnel to remotely comprehensively analyze the filter bag pressure status data and other information, and decide the next step of operation and management; when the remote control unit monitors and analyzes the production process In emergencies such as filter bag pressure overload, the emergency manual dust removal switch module device is used to transmit back to the server of the information centralized unit through the network interface. The server analyzes the specific information processing unit according to the transmitted address information, and outputs emergency control through the output interface circuit. Signal, control PLC manual dust removal processing, effectively realize dust removal monitoring.
