Industrial flow anti-misoperation system and industrial flow anti-misoperation method

Abstract

The invention provides an industrial flow anti-misoperation system and an industrial flow anti-misoperation method. The anti-misoperation system comprises a control system, an anti-misoperation lock, a computer key, and a parameter acquisition device. The control system is communicated and connected with the computer key. The anti-misoperation lock is disposed on operation equipment, which has a requirement on prevention of manual misoperation during a technological flow process, and is used to lock the operation state of the operation equipment. The parameter acquisition device is communicated and connected with the control system, and is used to acquire real-time parameters during the technological flow process in a real-time manner, and is used to transmit the acquired parameters to the control system synchronously. The control system is used to determine whether an operation condition or an operation requirement is satisfied according to the current real-time parameters. The computer key is provided with a code reading device and an unlocking device used to unlock the anti-misoperation lock. The anti-misoperation system and the corresponding anti-misoperation method are advantageous in that correct operation of operators on the operation equipment requiring the manual operation during the technological flow process is guaranteed, and the industrial flow anti-misoperation system is capable of preventing the misoperation effectively.

Description

【Technical field】 [0001] The invention relates to a technology for preventing misoperations in the technological process, in particular to an anti-misoperation system and method for industrial processes. 【Background technique】 [0002] At present, the prevention of misoperation in the technological process is very important in the national economy. Once the accident caused by a mistake is extremely serious, in addition to strengthening the organization and preventing misoperation in the management of anti-misoperation equipment or appliances, it is necessary to gradually apply advanced Technical means are used to improve the effectiveness of management, in order to improve the efficiency and reliability of management, and reduce errors that may be caused by human negligence. [0003] Especially in the fields of petroleum and petrochemical, coal metallurgy, and power plants, the process operation is mainly controlled by on-site valves and electrical switches. Among them, the ...

Problems solved by technology

[0005] Currently, on-site operations mainly rely on management measures such as paper-based operation confirmation cards and guardianship systems. figure 1 As shown in the "well opening operation confirmation card", there is no technical means to ensure the correctness of the operation in the whole process, so there are many human safety hazards

For example, due to the lack of experience and skills of new recruits, or the decline of judgment due to fatigue work, or the omission of shifts, which may easily lead to mistakes, or the lack of responsibility of the personnel to violate the rules; therefore, misoperations caused by human factors on site often occur, and The consequences of industrial misoperation are very serious, and it is easy to cause abnormal production, pressure suppression, unplanned shutdown or production stoppage, equipment accidents, personal injury and death
