Integrated monitoring system for tank car operating flow rate

Abstract

This application discloses an integrated monitoring system for the flow rate of a tank car, including a PKS system, a flow rate monitoring module, and 13 weighbridges; the flow rate monitoring module is coupled to the PKS system through a two-line switching network, and the flow rate monitoring module includes a planning management unit, Flow rate monitoring unit, data management unit, and data processing unit; the PKS system is respectively coupled to the flow rate monitoring module and 13 weighbridges through a two-wire switching network. The PKS system includes a main server, a redundant server, and 4 operating sub-stations; 13 weighbridges are coupled with the main server through a two-wire switching network, and are used to transmit the data of the weighbridge to the main server. The present invention can calculate the real-time tank car operating flow rate value, monitor the tank car operating flow rate through the flow rate monitoring unit, and alarm according to the flow rate alarm threshold combined with the PKS system. There is no need for manual input of job data, and historical records can be formed, which can be exported regularly for subsequent viewing.

Description

technical field [0001] The invention relates to the field of complete monitoring of tank car loading and unloading operations, in particular to an integrated monitoring system for tank car operating flow speed. Background technique [0002] Currently, METTLER TOLEDO metrology-grade weighbridges are used as the measurement equipment for the loading and unloading of vehicle tankers, and the list is filled out according to its stable data as the basis for the final trade transfer. The weighbridge only displays the current weight in pounds without any other parameters. In the central control room, Honeywell's PKS process control system and Enlafor radar level gauge system are used to monitor the flow of the storage tank, and the operating flow rate is calculated according to the change of the storage tank flow per unit time. In the process of using in recent years, it is found that there are some disadvantages in this flow rate monitoring method. [0003] 1. The flow rate data...

AI Technical Summary

Problems solved by technology

However, when a single storage tank is loaded with multiple tankers at the same time, it is impossible to determine the operating flow rate of a single tanker, and it is impossible to accurately control the safe flow rate

[0005] 3. PKS has no historical data for real-time flow rate data, and regular management functions. It cannot manage flow rate operation data in batches, and cannot look back at historical accident data.

[0006] 4. The flow rate displayed on the PKS monitoring interface is volumetric flow rate, without density conversion function, unable to convert real-time mass flow rate according to density, unable to display remaining amount, planned amount progress percentage and other data that can improve the work efficiency of operators

[0007] 5. PKS is Honeywell's internationally certified software, which cannot add computing functions, and cannot add non-certified scripts and software

[0008] 6. The operators in the billing room manually input the operation information such as tare weight, gross weight and net weight, which has potential errors, and there is no historical record of input and modification, so it cannot be verified
