Embodiment

[0035] At present, power plants implement centralized control of boilers, steam turbines and generators, and use distributed control system (DCS) to monitor and control production. For units with a single capacity of 300MW, DCS has more than 40 interfaces, and about 1,000 parameters need to be monitored. Parameter importance, grading the parameters:

[0036] 1. Category A: If the parameter exceeds the limit, catastrophic consequences will occur, and strict monitoring is required, such as main steam pressure, steam turbine speed, boiler drum water level, etc. Set a type A timer on the type A parameter measuring point interface of the DCS interface. The time interval between checking the parameter twice is not more than 5 minutes. When checking the parameter, the timer is cleared at the same time.

[0037] 2. Class B: If the parameter exceeds the limit, it will cause equipment damage, cause the unit to trip, reduce output, etc., such as the bearing temperature, vibration, heater...

Abstract

The invention relates to an inspection system and an inspection method for a computer multi-interface production control system, and belongs to the monitoring field of a control system. According to the technical scheme of the invention, the system comprises a plurality of system control interfaces provided with monitoring buttons and warning lamp signs. Each system control interface is provided with a corresponding periodic task and a corresponding timer, wherein the periodic time is preset for the periodic task and the periodic time is calculated by the timer. According to the above periodic task, the control personnel of the production control system click the monitoring button of a system control interface so as to generate a monitoring report. Within the periodic time, the warning lamp sign is displayed in a normal color from the zero-time to the time moment for the control personnel to click the monitoring button. Within the periodic time, if the control personnel do not click the monitoring button, the warning lamp sign is displayed in an alarm color. The monitoring report is stored in a monitoring module. The monitoring module counts the monitoring report situation of each system control interface and generates the monitoring quality according to monitoring reports and monitoring weights within the shift operation time.

Description

technical field [0001] The invention relates to a computer multi-interface production control system inspection system and method thereof, belonging to the monitoring field of control systems. Background technique [0002] Most of the production systems of large factories are controlled by centralized computer. There are many interfaces in the production control operating system, and many parameters need to be monitored and adjusted. Moreover, due to the small number of employees, high labor intensity, and paralysis of some production personnel in modern enterprises, the production personnel do not view the interface in time. As a result, the abnormal parameters are not found in time, and then develop into an accident, resulting in equipment damage and casualties. At present, there is no system or device for monitoring the work quality of the control personnel in the market, so it is impossible to effectively supervise and evaluate the work quality of the staff.
