Embodiment Construction

[0011] ENRAF liquid level automatic measurement integrated system solution

[0012] Considering that the oil depot is composed of many large oil tanks, and these oil tanks are distributed in different spaces, there is a certain distance in the physical location, and the measurement points are scattered, and the distributed measurement technology based on the network can better meet the requirements. Requirements for centralized measurement of multi-tank signals.

[0013] The liquid level measurement signal of each oil tank can be collected through the field communication unit CIU of ENRAF Company. The field communication unit belongs to the data concentrator, which can continuously poll data from field devices and store these data in the buffer memory. Whenever a data request is received, the CIU can immediately send a batch of stored data from the updated buffer memory. CIU field communication unit supports MODBUS communication protocol. Since a CIU field communication unit...

Abstract

The invention discloses a large-scale multiple oil-tank liquid level automation measurement integration system. The system comprises: an oil tank measurement sensor group, an on-site junction box, a communication unit CIU, a MODBUS gateway, a switch, a control operation station and a database server. The oil tank measurement sensor group is connected with a communication unit CIU bus through the on-site junction box. The communication unit CIU is connected with the liquid level measurement control operation station. The communication unit CIU is directly connected with the switch through the MODBUS gateway. In the invention, all functions of original liquid level measurement can be maintained; oil tank information integration can be realized; a information construction requirement of multiple oil tank concentration measurement can be satisfied. The oil tank measurement information is divided into two parts to display and store, which raises redundancy of the system.

Description

technical field [0001] The invention relates to a large-scale multi-tank liquid level automatic measurement integrated system in the automatic measurement of an oil depot. Background technique [0002] Oil depots usually consist of multiple large oil tanks distributed in different areas, storing various oil products. The large oil tank liquid level automatic measurement integrated system can realize the automatic liquid level measurement of multiple oil tanks. It is composed of liquid level measuring instruments, temperature measuring instruments, liquid level display instruments and so on. The oil tank automatic measurement system mainly realizes the monitoring of the state of the oil stored in the oil tank in the reservoir area, provides real-time state parameters of the stored oil, and at the same time performs safety monitoring and alarm on the state of the oil tank storage environment. At present, in the automatic measurement of oil tank liquid level, the automatic mea...
