Scattered material storage tank tankful detection and control method

Abstract

The invention relates to a scattered material storage and transportation technology in a physical distribution storage and transportation system. The invention discloses a scattered material storage tank tankful detection and control method which is realized in a way that: a tankful level detection device and an arithmetic control unit, which are arranged on a storage tank moving discharging car, are provided; the tankful level detection device moves among charging tanks along with the discharging car; the tankful level detection is carried out on the material storage tanks in the charging process, so that the tankful detection can be carried out on all the material storage tanks by using only one tankful level detection device; and the arithmetic control unit is used for control; and the arithmetic control unit can process, calculate and control the data detected by the tankful level detection device, and carries out the data communication with a ground system PLC or computer. Compared with the traditional scattered material storage tank tankful detection system, the detection and control method of the invention has the advantages of convenient detection, easy control, simple structure of devices for implementing the detection method, small quantity of the devices and cables, low failure rate of the system equipment, and small maintenance quantity.

Description

technical field [0001] The invention relates to bulk material storage and transportation technology in logistics storage and transportation system. Background technique [0002] During the transportation, processing and processing of bulk materials, storage tanks are often required to store materials in the middle process. During the storage of materials into the storage tank, it is necessary to detect the material level of the material loaded in the storage tank. If the filling is too full, the material will overflow the tank and cause production accidents. Therefore, the storage tank in the automatic bulk material storage and transportation system is generally equipped with a full material detection device. When the material level in the storage tank reaches or exceeds the predetermined full material position, the full material detection device will send out an alarm. Signal, so that the charging system equipment stops continuing to charge the storage tank, avoiding the o...

AI Technical Summary

Problems solved by technology

[0006] 1. In the prior art, each storage tank must be equipped with a full tank material level detection device. If there are many storage tanks, many full tank material level detection devices must be installed respectively. The full tank material level detection device equipment Need a lot

[0007] 2. The installation bracket, inspection hole, cover plate and other infrastructure of the full tank level detection device need to be prefabricated in each storage tank, and the amount of infrastructure construction is large

Generally, the storage tanks are at an altitude of tens of meters, and the system control devices are installed far away from the storage tanks on the ground, which requires a large number of cables and cable laying facilities, and the construction cost is very high.

[0009] 4. In the existing method and device for detecting the fullness of the bulk material storage tank, there are many devices, many connecting cables, and the system structure is complicated, resulting in many system failures and a large amount of maintenance, so that the corresponding maintenance costs are also large
