Description

Integrated monitoring system for tank car operating flow rate

technical field

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

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.

1. The flow rate data is calculated according to the change of the liquid level of the storage tank. The liquid level of the storage tank with a large volume changes slowly. It usually takes 5 minutes to display the initial flow rate, and the control of the initial flow rate is usually the key point.

2. When a single storage tank is loaded and unloaded by a single tank truck, the flow rate calculated from the change of the tank liquid level through PKS can represent the tank truck operation flow rate. 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.

3. PKS has no historical data and regular management functions for real-time flow rate data, so it cannot manage flow rate operation data in batches, and cannot check historical accident data.

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, and unable to display remaining amount, planned amount progress percentage and other data that can improve the work efficiency of operators.

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

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