The industrial remote magnetic flap level gauge is a pressure vessel for storing and transporting gas. The remote transmission magnetic flap level gauge refers to the combustible gas, which has been included in the “Safety Supervision Regulations for Remote Magnetic Flap Level Gauge”. Packaging materials such as compressed gas, liquefied gas, pressurized dissolved gas, etc. (such as oxygen remote magnetic flap level gauge, liquefied petroleum gas tank, chlorine cylinder, liquid nitrogen cylinder), are widely used in production and life fields, but Accidents such as explosion, fire, leakage, poisoning, and environmental pollution are prone to occur during filling, storage, loading and unloading, transportation, storage and use.
At present, offshore oilfields use remote magnetic flap level gauges (oxygen-containing remote magnetic flap level gauges, acetylene remote magnetic flap level gauges, nitrogen remote magnetic flap level gauges, argon remote magnetic flap level gauges). The plate level gauge, the carbon dioxide remote magnetic flap level gauge, the LPG remote magnetic flap level gauge and the high-energy liquefaction remote magnetic flap level gauge) have the following problems:
1) There are a large number of scattered, highly dangerous mobile remote magnetic flap level gauges on offshore platforms;
2) There are phenomena such as unscheduled use and loss of the remote magnetic flap level gauge, which causes a lot of waste;
3) Lack of modern real-time monitoring methods for the deployment and circulation of remote magnetic flap level gauges;
4) The complete use process of the remote magnetic flap level gauge cannot be monitored;
5) The rent calculation of the remote magnetic flap level gauge is complicated, the workload is large, and it is easy to make mistakes.
In order to solve the above problems, this paper proposes to design a set of intelligent remote magnetic flap level gauge management that uses radio frequency identification technology (RFID) to set up files, regularly check, real-time monitor, and perform performance analysis. System and evaluate its application effect.
1 Overview of the circulation of industrial remote magnetic flap level gauges in offshore oilfields
There are a large number of platforms in my country’s offshore oilfields, mainly distributed in the Bohai Sea, the eastern seas of the South China Sea and the western seas of the South China Sea. The platforms are far away from the land and the supply of materials depends on shuttle tugs. The offshore facilities are basically filled with external units, and the remote magnetic flap level gauge is rented internally, and the method is returned after use. The remote magnetic flap level gauge is sent from the remote magnetic flap level gauge factory to the wharf/warehouse to start calculating the rent, and the remote magnetic flap level gauge is returned to the remote magnetic flap level gauge factory to stop calculating the rent. . There are also remote magnetic flap level gauges borrowed and returned between various offshore platforms, as shown in Figure 1.

1) With electronic labels as the main line, matching labels for steel cylinders, monitoring the entry and exit of steel cylinders on various platforms;
2) Automatically collect, locate and count the storage management process of gas cylinders, and automatically alarm when in a dangerous state;
3) Non-contact identification remote magnetic flap level gauge, wireless data transmission;
4) Calculate the distribution information of remote magnetic flap level gauges from delivery to user to recovery;
5) Statistics on the number of detained remote magnetic flap level gauges;
6) Weekly/monthly/quarterly/yearly use of remote magnetic flap level gauge statistics for each platform;
7) The weekly/monthly/quarterly/annual use of remote magnetic flap level gauge cost statistics for each platform.
3 Architecture, hardware composition and use of intelligent management system for industrial remote magnetic flap level gauge
The intelligent management system of industrial remote magnetic flap level gauge is composed of four layers, including electronic tags, terminals, data collection and database, with network and staffing:
1) Use the platform office network to transmit data;
2) The tag data can be collected offline in the warehouse and on the device and uploaded when the network is available;
3) One system configuration server, and all clients are accessed through the branch office network;
4) The warehouse/device is equipped with 1-2 terminals, and the tags are manually updated by the sender and receiver of the remote magnetic flap level gauge.
The main hardware of the system is composed of the following parts:
1) Passive anti-metal electronic tags;
2) Explosion-proof handheld terminal;
3) Reader.
The system uses RFID (Radio Frequency Identification) technology, which is easy to control, simple and practical, and flexible in control. The system uses the electronic tags used by the wireless radio frequency automatic identification technology to uniquely identify the remote magnetic flap level gauge, uses an explosion-proof handheld terminal to collect and process the remote magnetic flap level gauge recovery information, and uses the wireless network to transmit it back to the cloud The server, recorded the relevant data information of the remote magnetic flap level gauge.
The use of the system mainly has the following steps
1) Distribution of remote magnetic flap level gauge
When offshore facilities need to use gas, the terminal will distribute and transport the remote magnetic flap level gauge according to the demand. The distribution process of the remote magnetic flap level gauge is as follows:
①Fill out the gas demand form for each platform;
②The terminal warehouse rents a corresponding number of remote magnetic flap level gauges from the gas plant, and updates the corresponding label, writes the remote magnetic flap level gauge information, and prepares to paste;
③After the remote magnetic flap level gauge arrives at the wharf warehouse, the management staff will label the remote magnetic flap level gauge with the updated data;
④Generate the distribution record of the remote magnetic flap level gauge on the handheld terminal and transmit it to the enterprise back-end database;
⑤ When the remote magnetic flap level gauge arrives on the platform, the platform material management personnel use the handheld terminal to scan the electronic label of the remote magnetic flap level gauge body to confirm and receive the remote magnetic flap level gauge, production and reception records, Transfer to the enterprise back-end database.
2) Deployment of remote magnetic flap level gauge
When offshore production facilities need to borrow and return the remote magnetic flap level meter, the remote magnetic flap level gauge will be deployed. The deployment process of the remote magnetic flap level gauge is as follows:
① The small platform applies to the large platform for the deployment form of the remote magnetic flap level gauge, or accesses the platform to lend the platform to apply;
② After the lent platform is ready for the remote magnetic flap level gauge, record the remote magnetic flap level gauge information on the handheld terminal;
③ After the remote magnetic flap level gauge arrives at the access platform, the receiver uses a handheld terminal to scan the remote magnetic flap level gauge information for reception;
④ The sending and receiving records are transferred to the enterprise back-end database.
3) Recovery of remote magnetic flap level gauge
When the facility runs out of gas, it needs to return the remote magnetic flap level gauge to the dock in time. The recovery process of the remote magnetic flap level gauge is as follows:
① The return platform material manager creates a return form, scans the information to be returned to the remote magnetic flap level gauge with the handheld terminal, and submits it to the background database;
② The terminal/warehouse manager uses the handheld terminal to scan the remote magnetic flap level gauge information returned by the platform and receive it;
③ The sending and receiving records are transferred to the enterprise back-end database. The industrial remote magnetic flap level gauge intelligent management system automatically calculates the lease date and rent and generates various reports based on the transfer information of the remote magnetic flap level gauge stored in the database.
