2. Brief introduction of VF8000 data collector inspection management system
The inspection system is an equipment maintenance management system with spot inspection as the core. It is to achieve equipment reliability, maintainability, and economy, and to achieve the best management mechanism in the above three aspects. It is based on pre-established technical standards, A management method that inspects equipment at fixed points, regular intervals, methods, and standards.
The patrol inspection system was originally developed by the preventive maintenance system introduced by Japan from the United States. It advocates the dynamic management of equipment for all employees and the entire process, that is, a management mode with spot inspection as the core during the equipment operation stage, and this management is applied. The mode will effectively prevent “over-maintenance” or “under-maintenance”, reduce the incidence of equipment failures, and greatly reduce equipment maintenance costs.
Weishi inspection management system includes: electronic tags, VF8000 data collector, infrared communication socket, remote communication socket, GPRS wireless transmitter, SQL Server database, B/S network version inspection management software and other main parts.
3. Working process:
1. Define the device type
The inspection items of the same type of equipment to be inspected are often the same. For convenience, the equipment with the same inspection item is classified as the same equipment type, and the inspection items corresponding to the equipment type are uniformly set.
The inspection items are divided into 4 types: single option, multiple options, numerical value, and remarks.
Remarks: It is a category in which inspectors can freely input Chinese based on actual conditions. This situation often occurs when inspectors find some problems, but these problems are not in the set inspection items.
Take “reservoir pumps” and “syngas compressors” as examples to illustrate as follows:
Equipment type[01]：The inspection items of “Reservoir Pumps” include:
Outlet pressure (numerical value)
TRG indication (single option: normal, too high, too low)
Operation status (multiple options: normal, abnormal, fault)
Whether there is abnormal sound and leakage at the scene (multiple options: abnormal sound, no abnormal sound, leakage, no leakage)
Equipment type[02]：The inspection items of “Syngas Compressor” include:
Current (numerical value)
Oil level (numerical value)
Oil quality (numerical quantity)
Oil pressure (numerical value)
Oil temperature (numerical value)
Import and export pressure (numerical value)
Dry gas seal flow (numerical value)
Whether there is abnormal sound and leakage at the scene (multiple options: abnormal sound, no abnormal sound, leakage, no leakage)
2. Define location card and personnel card:
Inspection location card (ie electronic tag), each electronic tag has a unique serial number, use the location card to identify each inspected device, and set the device type corresponding to the inspected device in the computer software to determine the device Inspection items.

3. Download the file
Download the inspection points, personnel cards and related equipment type data as files to the VF8000 data collector. VF8000 and computer download files through Irda infrared cradle.
4. Installation location card
Install the location card near the equipment to be inspected. The location card uses radio frequency technology, and the VF8000 can read the unique code when it is close to the location card. Therefore, it can be installed on the surface of the equipment or buried in a non-metallic body, but special anti-metal electronic tags are required when installing on a metal surface.

6. Upload inspection records
After the inspection, the inspection records in the VF8000 are uploaded to the inspection management system database, which is analyzed by the inspection management software, and various inspection reports are generated.
There are 4 ways to upload records:
Transmission via intranet computer terminal
If the application environment is an enterprise intranet environment, the inspection records can be uploaded to the inspection management system database through a nearby computer connected to the enterprise LAN. The terminal computer is equipped with an infrared cradle. The windows are aligned, and then communication is started.
620)this.style.width=620;” border=0>
Transmission via Ethernet
Only the VX5000N Ethernet remote communication socket, after connecting the network cable to the VX5000N, the VF8000 and VX5000N adopt infrared communication, and the inspection records in the VF8000 are saved in the VX5000N, and then the VX5000N is automatically connected to the server through the Ethernet. And upload the inspection records to the database.
There is 16M FLASH memory in VX5000N, which can save about 65000 inspection records. If you encounter a network failure, you can cache multiple records in the VF8000. Due to the use of FLASH to store records, the records will not be lost even if the VX5000N is powered off, and the records can be stored for more than 10 years. If the Ethernet cannot be repaired in a short time, the VX5000N and the server can also communicate directly with the server through infrared or serial port to upload records.
Because VX5000N adopts embedded technology inside, it is not interfered by viruses. Compared with computer terminals, it is more stable and reliable and has a long lifespan, so it is a good choice.
Transmission via telephone line
The difference from VX5000N is that VX5000M can upload inspection records to the database via telephone line instead of Ethernet. However, it is required to connect the telephone line MODEM on the server side. If there are more VF8000s, the MODEM pool can be used on the server side to avoid conflicts.
VX5000M only occupies the phone line when transmitting data, and does not affect the normal use of the phone, that is, you can connect the VX5000M to the original phone line in parallel.
Transmission via GSM network
Use the GPRS transmitter of the GSM network to establish a connection with the wireless receiving server through the Internet, and transmit the inspection records to the database. In this way, the wireless receiving server must be connected to the Internet (Internet public network).
Different from the remote cradle mode, the GSM mode transmits data in real time, without the function of data caching. In addition, GPRS transmission requires monthly payment to China Mobile based on traffic and monthly rent. The advantage is that it is more flexible and does not require Ethernet, telephone lines, computers and other equipment.
Direct transmission via infrared cradle
When the system is not very large, the inspection records can also be transmitted through direct communication with the database server through the infrared communication socket.
This method is the simplest, and the equipment investment is the least. The disadvantage is that it cannot be adapted when there are many users and the factory is relatively large.
Fourth, the network inspection topology diagram
