[0028] The south line vent tank device includes two horizontal vent tanks, and the north line vent tank device includes two horizontal vent tanks.

[0029] A liquid level meter is installed in the manhole of each horizontal oil tank, and an audible and visual alarm, a tank pre-processor and a lightning protection box are installed next to the wellhead.

[0030] The south line straight refueling device includes sixteen sets of refueling devices, which are evenly divided into four groups and the four groups are arranged on the same straight line; the north line straight refueling device includes four sets of refueling devices, which form a group.

[0031] The four groups of refueling devices of the south line straight refueling device are all connected to the lightning protection box; one group of refueling devices of the north line straight refueling device is connected to the lightning protection box.

[0032] The operating console contains a serial port server, a switch, a DC power supply, a lightning protection module and four photoelectric conversion modules. The four photoelectric conversion modules are respectively connected to the optical fibers of the south line linear refueling device, the south line emptying tank device, the north line linear refueling device and the north line emptying tank device. The operating console is equipped with a UPS and a printer, and the UPS is connected to an AC 220V power supply.

[0033] The lightning protection module includes AC power lightning protection module, DC power lightning protection module and signal lightning protection module. Specific embodiment:

[0035] In this embodiment, there are 20 sets of linear refueling devices, 4 sets in a group, a total of 5 groups; distributed in the north and south areas, of which the south area has four groups (16 sets) of refueling devices, which are distributed on a straight line with a total length of no more than 600 meters, and the north area has one group (4 sets) of refueling devices. The north and south areas are about 1,000 meters apart. There are two horizontal emptying oil tanks in the south and north areas respectively, and the data needs to be integrated into the filling station duty room about 2,000 meters away.

[0036] This embodiment needs to integrate the oil delivery data of the linear refueling device and the liquid level data of the horizontal emptying oil tank into the oil depot automatic monitoring system, so the corresponding equipment needs to be connected to the network, and then an operating table and a monitoring computer are set up in the duty room of the filling station to monitor the operation of the entire system.

[0037] 1. Horizontal emptying oil tank level measurement

[0038] In the linear refueling system, there are four horizontal venting oil tanks, divided into two groups, two in each group, two in the north and south areas. Each horizontal venting oil tank needs to be installed with a liquid level monitoring system, and a magnetostrictive level meter is used to monitor the liquid level in the horizontal venting oil tank.

[0039] It is designed to install a MET-I liquid level meter in the manhole of each horizontal oil tank, and install a lightning protection box, an audible and visual alarm and a TFP-100 tank pre-processor next to the wellhead (to facilitate on-site reading of liquid level, temperature and other data). The monitoring signal is uploaded to the liquid level monitoring industrial computer in the duty room of the filling station in the form of RS-485 bus communication.

[0040] Since the distance between each group of horizontal venting oil tanks and between the horizontal venting oil tanks and the duty room of the filling station is far (all over 1000 meters), RS-485 signals cannot be transmitted directly, so optical fiber transmission is adopted. Specifically, an RS-485 photoelectric conversion module is installed next to each group of horizontal venting oil tanks to convert RS-485 signals into optical signals, which are then transmitted to the duty room of the filling station and then restored to RS-485 signals through an RS-485 photoelectric conversion module, and then input into the liquid level monitoring industrial computer.

[0041] In addition to the MET-I level gauge and TFP-100 tank preprocessor, there are also sound and light alarms, DC 24V power supplies, RS-485 photoelectric conversion modules, AC power lightning protection modules, DC power lightning protection modules, and signal lightning protection modules, including accessories such as fiber pigtail jumpers. Because the area in front of the tank is an explosion-proof hazardous area, all electrical components must be installed in a flameproof box to meet relevant explosion-proof requirements.

[0042] The system requires an AC 220V power supply on site. Each set of horizontal oil venting tanks consumes about 30W of power and should also have a good lightning protection and grounding system.

[0043] 2. Linear refueling control system communication

[0044] In this embodiment, there are 20 sets of linear refueling devices, 16 of which are in the south area, evenly divided into four groups and distributed along a straight line, and 4 sets are also distributed along a straight line in the north. The communication mode of the linear refueling control system is RS485 bus mode. The data of the north and south areas need to be transmitted to the linear refueling industrial computer in the duty room of the filling station more than 1,000 meters away. Limited by the communication distance, bus integration is carried out respectively near the horizontal emptying oil tanks at the two refueling areas, and the bus is laid from the middle to both sides to minimize the length of a single bus. Similar to liquid level monitoring, an optical fiber is laid from each of the two refueling areas (shared with the optical fiber of the respective horizontal emptying oil tanks) to the duty room of the filling station, and RS-485 long-distance communication networking is realized through two pairs of RS-485 photoelectric conversion modules. Among them, the explosion-proof box where the lightning protection and photoelectric conversion modules are installed is combined into one box with the respective photoelectric boxes of the emptying tank liquid level.

[0045] 3. Filling station duty room

[0046] An operating table is configured in the duty room of the filling station, which contains four RS-485 photoelectric conversion modules, corresponding to the optical fibers in the north and south areas respectively, and is used to restore the optical signals transmitted from the site into RS-485 signals; a four-port serial port server and switch, which convert the RS-485 bus signals into TCP / IP signals so that the system can be integrated into the corresponding industrial computer; a UPS and a printer are provided; there is also a DC 24V power supply and a lightning protection module.

[0047] One liquid level monitoring industrial computer and one linear refueling industrial computer are configured in the duty room of the filling station, running the corresponding monitoring software, and a data interface for linking to the upper-level information system is reserved to facilitate overall system integration in the future.

[0048] The model of the liquid level monitoring industrial computer and the linear refueling industrial computer is IPC-610E.

[0049] The main functions of the monitoring software include: system overview, detailed parameter display and setting, data change history query and trend chart display, report output, user authority management, etc., and a data interface is reserved for connection with the upper management system.

[0050] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the utility model, or are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
