The invention discloses a control method of a nuclear power station safety level DCS. The control method includes the steps that two or more driving signals sent by equipment are received; the driving signals are subjected to priority ranking according to preset priority management logic; a first driving instruction is generated according to the ranked first driving signal so that an equipment driving device can execute operation according to the first driving instruction. According to the control method of the nuclear power station safety level DCS, in the control process of a nuclear power station safety level digital instrument control system, a multifunctional and intelligent control technology can be achieved. Besides, the invention discloses a multifunctional interface of the nuclear power station safety level DCS.

The maintenance strategy analysis method of instrument control equipment based on technical analysis includes the following steps: S1, defining the analysis boundary: defining the equipment types covered by the maintenance template, the equipment boundary of the equipment and the external interface, and the attribution of the equipment boundary; 2, listing and writing that device information sheet: listing and writing the device-related information analyzed by the analysis boundary defined in the step S1; S3, technical analysis: performing technical analysis on the equipment within the analysis boundary defined in step S1; S4, functional analysis: performing functional analysis on the equipment in the equipment information sheet written in the step S2 column; S5, making a maintenance decision; S6, task comparison and improvement suggestions. The technical analysis of this method is based on the equipment type. According to the equipment working principle and the actual operation and maintenance experience, the preventive maintenance task of the equipment is determined by the equipment failure mode analysis or the modification suggestion is put forward. The equipment reliability analysis is used to determine the appropriate preventive maintenance cycle.

The invention relates to an endoscopic instrument replacement method and device, electronic equipment and a readable storage medium. The endoscopic instrument replacement method comprises the steps that angle data of a triangular area channel, pitching angle data of a flexible channel and yaw angle data of the flexible channel are collected within a preset period; according to the angle data of the triangular area channel, judging whether the current state of the triangular area channel is the initial state of the triangular area channel or not; according to the flexible channel pitching angle data and the flexible channel yaw angle data, judging whether the current state of the flexible channel is in the initial state of the flexible channel or not; and according to the current state of the triangular area channel and the current state of the flexible channel, determining whether the endoscopic instrument can be pulled out or not. An endoscopic instrument control system automatically judges whether the endoscopic instrument can be pulled out and replaced or not according to the collected signals, the situation that an operator replaces the instrument without paying attention to the flexible channel, and consequently the instrument and the channel are damaged is effectively prevented, the operation safety is improved, and the operation efficiency is improved.
