本文根据对石油化工装置仪表和控制系统状态的设备现状，提出了仪表和控制系

Based on the current situation of the petrochemical plant instrumentation and control system status, as proposed instrumentation and control system status online and offline detection strategies, via a state data acquisition and communications protocols, the use of industrial cloud platform through the side development platform, the appliance development important data for the application development side, petrochemical collection instrumentation and control system status data and diagnostic information and data access to industrial mass cloud platform, using collaborative cloud + IIoT edge, failure prediction model is established, the collected data is analyzed, information and send real-time text messages, etc., and timely maintenance management and feedback, proposed maintenance solutions based instrumentation and control systems of industrial predictive cloud, to protect the integrity of the instrumentation and control system equipment.

Based on the current state of the equipment of the instrument and control system of the petrochemical plant, this paper puts forward the in-line detection and offline detection strategy of the instrument and control system status, and uses the industrial cloud platform through the status data collection and communication protocol, through the platform side development, equipment side development and application side development. Collect ingenuity data such as petrochemical instrument and control system status data and diagnostic information and access to the industrial cloud platform, use IIoT edge and cloud collaboration, establish fault prediction model, analyze the collected data, send important data and information in real time, and timely maintenance management and feedback, The predictive maintenance solution of instrument ation and control system based on industrial cloud is proposed to guarantee the integrity of instrument and control system equipment.

According to the status quo of instrument and control system in petrochemical plant, this paper puts forward the strategy of on-line detection and off-line detection of instrument and control system status. Through state data collection and communication protocol, using industrial cloud platform, through platform side development, equipment side development, application side development, the status data and diagnosis information of Petrochemical Instrument and control system are collected. Measure the data and connect it to the industrial cloud platform, use the iiot edge + cloud collaboration to establish a fault prediction model, analyze the collected data, send the important data and information in real time by SMS, and timely maintain management and feedback, propose predictive maintenance solutions for the instrument and control system based on the industrial cloud, and ensure the integrity of the instrument and control system equipment. 。<br>
