1. Why do petroleum and petrochemical enterprises need equipment inspection system?
Danger of petroleum and petrochemical plants: The petroleum and petrochemical industry is a dangerous industry with high temperature and high pressure, inflammable, explosive and toxic. The production process is complex and the equipment is huge. Minor accidents may have a great impact. Once an accident happens, it will easily lead to a vicious accident, such as Chongqing 12.23 blowout, which killed 243 people, poisoned 2 142 people and evacuated 65,000 local residents. Therefore, the petroleum and petrochemical industry has extremely strict requirements for safety management.
Traditional inspection methods can't manage inspectors efficiently and strictly: at present, the safety inspection of petroleum and petrochemical systems is mainly carried out through regular inspections by security inspectors and irregular spot checks by higher-level supervision departments: a movable dial is placed at the inspection site or equipment, and the security inspectors dial the clock of the dial to point to the inspection time every place; In addition, by throwing a note, the security inspector put the note with the inspection time in the carton to record the inspection. The superior department will conduct spot checks on the inspection of the security inspectors. It can be seen that this assessment method is very unscientific, that is, it is difficult to verify the time, and it is easy for some security inspectors to relax their vigilance, because a small operational error may lead to disastrous consequences. Propaganda and ideological work is important, but strengthening scientific safety inspection management methods is an effective way to avoid accidents.
Factory equipment should check the parameters every day to check whether the parts are in good condition. In the past, inspectors used paper notebooks to select the parameters of the equipment, so it was difficult to control the inspection time and the authenticity of the inspection data.
2. What kind of equipment should petrochemical enterprises choose?
Explosion-proof certificate: the factory environment of petroleum and petrochemical enterprises has strict requirements for electronic products. Under normal circumstances, factory workers are not even allowed to bring mobile phones into the factory to avoid unnecessary accidents caused by high temperature, high pressure and flammable and explosive equipment.
Detection equipment with few interfaces: There is a lot of dust in the factory, and the equipment with USB port is easy to be damaged, so choose the equipment with communication base for data transmission or infrared transmission.
Choose the equipment that suits you: If you need to record the parameters, running status, arrival time, date and name of the equipment in the spot check factory, you need to choose the Chinese V8 data collector. There are many kinds of data collectors, usually equipped with monitors. Because of the high temperature and high pressure in the factory environment, it is necessary to choose the equipment with organic light-emitting diode display instead of ordinary liquid crystal. The working temperature of organic light-emitting diode display is -40℃ ~+80℃, and its seismic resistance is higher than that of liquid crystal display, and it still shows clearly in the sun.
Three. Brief introduction of petroleum and petrochemical equipment inspection management system
Patrol inspection system is an equipment maintenance management system with spot inspection as the core. It is a mechanism to realize the reliability, maintainability and economy of equipment and the optimal management of the above three aspects. According to the pre-established technical standards, a management method of inspecting equipment by personnel, fixed points, on a regular basis, according to methods and standards.
Security patrol management system consists of patrol point, V8 data collector, infrared communication base, remote communication base (optional), management software (network version, Internet patrol version) and other main parts.
Four. Workflow: The following are the workflows of the two inspection systems.
Network version software V9.0: Factory-set server (windows2003 system, SQL Server2005 data)
Library), install V9.0 software on this server, as long as there is a WAN or LAN, you can query or upload inspection data, which is managed by the superior.
Department management level, assign authority to department heads, and let them perform their duties. Suitable for national chain stores or large factories and enterprises. 9.0 The system topology diagram and workflow are shown in the figure on the right:
1. Install and configure the server: Install the SQLServer2005 database and configure IIS.
2. Set up software: set up inspection points, inspection equipment, inspection items of inspection equipment, inspectors, inspection plans, etc. Taking an iron and steel group as an example, we set up three equipments: naphthalene packaging pump, drum crystallizer and power distribution cabinet: equipment name, inspection period and division of labor, equipment status, inspection method and outlet pressure of naphthalene packaging pump A.

4. Installation of inspection points: Install inspection points near the equipment to be inspected.
5. Patrol inspection: At the beginning of patrol inspection, the inspector first selects the inspector's name in the V8 data collector, that is, first determines the inspector's identity, and then begins to patrol the equipment of a line. After the inspector reads the inspection point, he displays the inspection items of this position on the screen of V8 data collector, and inputs the site status information of this position according to the prompt. After all items are input, the collector saves records, and the inspection record consists of equipment name, card reading time, card number and inspection items. In the process of inspection, this machine can query all the inspected equipment, task list, inspection project records and the next inspection location.
6. Upload inspection data: There are two ways to upload data. One is to prepare one or more computers in the workshop or office. This computer needs to be connected to a server (Internet or local area network), and the test data will be uploaded to this computer through a short-range infrared communication rack, and then uploaded to the server through the network. Second, prepare one or more remote communication racks in the workshop or office, connect with the server through network cable or telephone line, upload the inspection data through remote communication racks in infrared mode, and then upload it to the server through the network, so that the data can be uploaded even if there is no computer in the factory, without worrying about the trouble that the data cannot be uploaded due to the virus in the computer.
7. Check data: Any computer on the same network (Internet, LAN) as the server can check data.
Web browsing software: only public servers are set up, and users do not need to provide operating system, database and computer management.
Members, etc. Only engineers are responsible for setting and maintaining user information, and users only need to buy back products for use, without setting up software and receiving training; And as long as there is a network, you can upload and check the inspection data; With the network version of V9.0 multi-level management, authority distribution and other functions. The workflow and topology diagram are shown on the right.
1. Provide information such as the name and items of the equipment to be inspected, and the inspection engineer will help you set up the inspection system.
2. Download the inspection file to V8 data collector after the real engineer completes all the settings; Install the detection point near the equipment to be detected.
Due to the application of computer software, automatic identification and other high-tech technologies in the public security patrol management system, patrol records cannot be forged, thus ensuring the authenticity of statistical results. The system provides a scientific management basis for public security patrol work, and can completely put an end to the situation of evading patrol because of the existence of lucky paralysis.
Equipment inspection report:
* * * Statistical results can be based on different needs.
For example: original record query
Check the inspection data of 2010-10-2613: 23-2010-/2-0713: 23.
Note: The equipment point of "the first floor of synthetic compression" needs to check the operation, oil leakage and temperature of the oil station. Among them, "oil station operation" is a single-choice type, and both normal and abnormal should be selected; "Oil leakage situation" is a multi-choice type, and multiple options can be selected at the same time; "Temperature" is a numerical type, and you need to enter the numerical value of temperature.
