Description

Technical Field

[0001] The present application relates to a device early warning system and an early warning method thereof, belonging to the field of industrial safety and automation, and in particular to a safety early warning system and an early warning method thereof for obsolete devices. Background Art

[0002] With the rapid and sustained growth of my country's economy and the vigorous development of the petrochemical industry, China has become a major country in the world's petroleum and chemical industry. The petrochemical industry is an important pillar industry of the national economy. Petrochemical equipment is flammable, explosive, high temperature, high pressure and other characteristics, and the safety issues involved cannot be ignored. Equipment safety is not only related to the safety of people's lives, but also affects social harmony and stability. It is an important part of ensuring industrial safety production.

[0003] In recent years, the production environment of many enterprises has been continuously improved, but the long-running equipment has not been transformed and upgraded in time. Some equipment and facilities have been used for a long time since they were built, and some are even over-aged. The overall situation is relatively complicated. During the operation of old equipment, the safety risk of production will increase accordingly, and problems such as pipeline aging, equipment fatigue, and increased system failure rate will gradually emerge. Production stability and equipment reliability will also decrease year by year. However, from the perspective of resource utilization and cost reduction and gain, it is neither economical nor realistic to abandon all old equipment. Therefore, in order to further reduce the operating risks of old equipment and improve its safety management level, it is an inevitable requirement to carry out safety risk prevention and control of old equipment in an all-round way for the stable development of the petrochemical industry and resolutely curb major accidents.

[0004] In recent years, the corrosion problem of petrochemical equipment and pipelines has become increasingly prominent. A typical case is the Qingdao Huangdao oil pipeline explosion on November 22. The direct cause of the accident was: due to pipeline corrosion, crude oil leaked into the municipal drainage culvert. The volatilized oil gas mixed with air to form a flammable and explosive mixed gas. The leaked crude oil and mixed gas spread, diffused, and accumulated in the relatively closed drainage culvert, and exploded when encountering sparks. Corrosion is the enemy of safe production. The corrosion management and safety warning of old equipment are extremely important links in the prevention and control of equipment safety risks. They are of great significance to ensuring the safe operation of the equipment and avoiding major accidents. Summary of the invention

[0079] In one embodiment, the priority levels include: the first level priority is for devices where emergencies occur, the second level priority is for devices that have been built and put into use, and the third level priority is for devices that have been built but not put into use or are called devices without priority; wherein, in the second level priority, the priority level of the device is sorted by service time; when the construction time, commissioning time, and service time are the same, the priority level of the same type of device that has not undergone material upgrades is greater than the priority level of the device that has undergone material upgrades; when the construction time, commissioning time, and service time are the same and the material of the metal material used in the device is the same, the priority level of the same type of device that has experienced corrosion problems is greater than the priority level of the device that has not experienced corrosion problems.

[0080] In one embodiment, the priority index decision function is:

[0081] Traverse the emergency event set to check whether there is an ongoing emergency event. If there is, it is the first-level priority and output the priority index R=1;

[0082] If there is no ongoing emergency, determine whether the device is already in use. If it is already in use, it will be the second level priority.

[0089] For the equipment judged as the second-level priority, if there is no priority given to service time, construction time, or commissioning time, and the material has been upgraded and no corrosion problem has occurred, the output priority index R=7;

[0090] If the central control system queries a signal with a higher priority, the signal will be cached and wait for confirmation by the on-duty personnel before planning the warning timeline of the target device; if not, the warning timeline of the target device will be planned directly.

[0091] like Figure 2 As shown, the present application also provides a safety early warning method for obsolete devices based on a scheduling decision mechanism, including:

[0092] Step 1: The basic information identification system of the device identifies and enters the basic information of a device, and at the same time generates the decommissioning and scrapping information of the device in the device scrapping information management system, and synchronizes it to the comprehensive information database of the plant.

[0093] For example, when a new device A is registered, the basic information data of the target device is identified by the device basic information identification system. The basic information data of device A is composed of a set A = {a1, a2, ..., a i ,…,a n} means that a i is the i-th basic information of device A, 1≤i≤n, and the basic information data includes but is not limited to device type, process flow, raw material properties, commissioning time, service environment, and the structural type, selected materials, design service life, contact material properties and operating parameters of its key equipment. The information set A of device A is sent to the central control system through the device basic information identification system.

[0094] Step 2: The central control system receives the basic information identification system signal of the device and the information signal fed back from the comprehensive information database of the plant area, generates the warning timeline of the device, determines the warning level according to the priority level, and transmits it to the warning guidance system and user terminal.

[0095] After the central control system receives the basic information data A of device A, it uses the data to establish the safety warning evaluation priority index R for device A. A , R A =f(A,S,D,C). Among them, f(·) is the safety warning evaluation priority function. The historical event data of shutdown, maintenance, failure, accident, etc. experienced by the device during the entire service process is composed of the data set S = {s1,s2,…,s j ,…,s m} means, s j It represents the jth event in the set of historical events experienced by the device during its entire service life, 1≤j≤m. In addition, D represents the planned scrapping time of the device, and C represents whether there is an emergency event for the device at present.

[0096] While the central control system receives the basic information of device A and starts processing the safety warning issues of device A, the device scrapping information management system generates the deactivation and scrapping information of the device and synchronizes it to the comprehensive information database of the factory.

[0097] The corresponding data set S can be established by searching the factory comprehensive information database for historical events related to the production device, such as video slices, work orders, construction records, etc.

[0098] Data set D can be obtained by querying the device scrapping information management system.

[0099] The current emergency event information C can be obtained through the feedback signal of the emergency system.

[0100] Through the pre-planned hierarchical warning scheduling strategy for obsolete devices, the decision function f(·) can be obtained. The output value of this decision function is the safety warning evaluation priority index R of device A. A The smaller the value of the priority index is, the higher the priority of the device is.

[0101] In this application, the plant comprehensive information database is also called the plant old equipment comprehensive information database.

[0102] When an emergency occurs in an installation in the factory, the central control system can redefine and adjust the warning levels of other installations in the comprehensive information database of the factory based on the emergency signal received, so as to avoid related accidents and cause more losses.

[0103] In one embodiment, the first level priority is for devices where emergencies occur, the second level priority is for devices that have been built and put into use, and the third level priority is for devices that have been built but not put into use or are called devices without priority; wherein, in the second level priority, the priority level of the devices is sorted by service time; when the construction time, commissioning time, and service time are the same, the priority level of the same type of devices that have not undergone material upgrades is greater than the priority level of devices that have undergone material upgrades; when the construction time, commissioning time, and service time are the same and the material of the metal material used in the device is the same, the priority level of the same type of devices that have experienced corrosion problems is greater than the priority level of devices that have not experienced corrosion problems.

[0104] The tree structure diagram of the priority index decision function is as follows: Figure 3 As shown, the decision function includes the following steps when calculating the priority index R:

[0105] Traverse the emergency event set to check whether there is an ongoing emergency event. If so, it is the first level priority and output R=1.

[0106] If there is no ongoing emergency, determine whether the device is already in use. If it is already in use, it will be given the second level priority.

[0107] If it is determined that the equipment is not in use, there is no priority and the output is R=8.

[0108] In the device determined to have the second level of priority, if there is a situation where the service time is prioritized, R=2 is output.

[0109] In the equipment judged as the second-level priority, if there is no service time priority and there is a construction time priority, then R=3 is output.

[0110] In the equipment judged to have the second-level priority, if there is no situation where the service time and the construction time are prioritized, but there is a situation where the commissioning time is prioritized, then the output is R=4.

[0111] In the equipment judged to have the second-level priority, if there is no priority given to the service time, construction time, or commissioning time, and no material upgrade has been implemented, then the output is R=5.

[0112] In the equipment judged as the second-level priority, if there is no priority given to the service time, construction time, and commissioning time, and if material upgrades have been implemented and corrosion problems have occurred, then the output is R=6.

[0113] In the equipment judged to have the second-level priority, if there is no priority given to the service time, construction time, or commissioning time, and if material upgrades have been implemented and no corrosion problems have occurred, then the output is R=7.

[0114] If the central control system queries a signal with a higher priority, the signal will be cached and wait for confirmation by the on-duty personnel before planning the warning timeline of the target device; if not, the warning timeline of the target device will be planned directly.

[0115] The warning timeline is generated by the central control system and transmitted to the warning guidance system and user terminals.

[0116] Step 3: The early warning guidance system monitors and reminds the deactivation or scrapping of the device according to the early warning timeline of the device.

[0117] Device A is decommissioned or scrapped according to the early warning guidance. After decommissioning or scrapping, the device scrapping information management system will upload information such as the actual decommissioning and scrapping date of device A to the comprehensive information database of old devices in the factory area, and complete the update of the comprehensive information database of old devices in the factory area.

[0118] As the number of devices and their information data using the safety warning method for obsolete devices gradually increases, the conclusions drawn by the warning method will also undergo adaptive changes. The more data, the more perfect the system will be, and the more accurate and operational the safety warning method based on the scheduling decision-making mechanism will be.

[0119] The above are only a few embodiments of the present application and do not constitute any form of limitation to the present application. Although the present application is disclosed as above with preferred embodiments, it is not intended to limit the present application.
