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

Embodiment 1

[0040] see figure 1 with figure 2 Shown is a specific embodiment of the tank truck operating flow rate integrated monitoring system described in this application. The tank truck operating flow rate integrated monitoring system 100 includes: a PKS system 110, a flow rate monitoring module 120, and 13 weighbridges 130, wherein,

[0041] The flow rate monitoring module 120 is coupled to the PKS system 110 through a two-wire switching network, and the flow rate monitoring module 120 includes a plan management unit 121, a flow rate monitoring unit 122, a data management unit 123, and a data processing unit 124. The software company issues ideas and requirements, and the software company modifies the PKS system 110 within the scope allowed by the certification. The flow rate monitoring module 120 is rooted in the main server 111 of the PKS system 110 and communicates with the PKS system 110. Its subunits assume different The function carries out data fetching communication separat...

Embodiment 2

[0056] On the basis of embodiment 1, see image 3 with Figure 4 Shown is a practical embodiment of the integrated monitoring system for tank car operating flow rate described in this application.

[0057] image 3 The unloading status record table (only exemplifying the unloading data on several weighbridges) derived for the data management unit 123, image 3 The table includes the position of the tank car unloaded on different weighbridges, the name of the product to be unloaded, the name of the customer, the license plate number of the tank car, the amount of product to be unloaded (planned amount), and the total weight of the tank car (gross weight), tank car empty weight (tare weight), subtract the tare weight from the gross weight to get the actual unloaded product amount, and subtract it from the planned amount to get the difference between the two, so as to check whether the product is completely unloaded . This table can also be modified manually, just click the e...

Abstract

The invention discloses an integrated monitoring system for the operation flow rate of a tank truck. The integrated monitoring system comprises a PKS system, a flow rate monitoring module and 13 wagon balances. The flow rate monitoring module is coupled with the PKS system through a two-wire switching network and comprises a plan management unit, a flow rate monitoring unit, a data management unit and a data processing unit; the PKS system is coupled with the flow rate monitoring module and the 13 wagon balances through the two-wire switching network and comprises a main server, a redundant server and four operation substations; the 13 wagon balances are coupled to the main server through the two-wire switching network for transmitting the wagon balance data to the main server. The real-time tank truck operation flow rate value can be calculated, the tank truck operation flow rate is monitored through the flow rate monitoring unit, and an alarm is given according to the flow rate alarm threshold value and the PKS system. The operation data does not need to be input manually, and can form a historical record and be exported periodically, so that the follow-up check is facilitated.

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...
