Detailed Description
As shown in fig. 1, an automatic quantitative loading system with safety protection function at least includes: the system comprises an input/output interface unit 1, a central control station 2, a communication module 3, a mass flow meter 4, a loading valve 5, a loading pump 6, a safety valve 7 and an anti-static overflow device 8, wherein the input/output interface unit 1 is arranged in a post master control chamber and is used for setting the loading amount, and remotely operating the loading valve and the safety valve; the central control station 2 is arranged in the cabinet room, is used for signal acquisition and processing, and is used for storing and controlling an automatic loading program and a safety interlocking program; the communication module 3 is arranged in the control cabinet and used for data acquisition and transmission of metering; the mass flow meter 4, the loading valve 5, the loading pump 6 and the safety valve 7 are arranged on a field loading pipeline, are used for collecting and calculating loading flow data and are used for conveying loading media; the anti-static overflow device 8 is arranged on a field loading platform and used for protecting and controlling the safety interlock of static electricity and overflow.
The input/output interface unit 1 is connected with a central control station through an optical fiber Ethernet; the central control station 2 is connected with the communication module 3 through a Profibus-DP.
The communication module 3 is connected with the mass flowmeter 4 through an RS-485 communication interface.
The interface of the mass flow meter 4 is provided with two branches, the first branch is connected with the loading valve 5, the safety valve 7 and the loading pump 6 in series, and the loading pump 6 is connected with the storage tank pipeline; the second branch is electrically connected with the anti-static overflow device 8.
When loading operation is carried out, firstly, the anti-static overflow device 8 is connected with a tank car, the anti-static overflow device 8 uploads signals of on-site prompt overflow and static signal states to the input and output interface unit 1 through the RS-485 communication interface, the communication module 3 and the central control station 2, if the overflow and static signals are automatically prompted to be normal, the input and output interface unit 1 sends a command to the safety valve 7 through the central control station 2, the communication module 3 and the RS-485 communication interface, and the safety valve 7 is opened;
