Universal computer capable of realizing container mobile loading and unloading mechanical control based on PLC (Programmable Logic Controller)

Abstract

The invention discloses a universal computer capable of realizing engine electronic throttle control, gearbox automatic control, accessory control, cab intelligent management and the like for a emptycontainer stacking machine based on a PLC (Programmable Logic Controller). The universal computer comprises the steps of computer production, software production, computer installation, parameter input and computer debugging. Step one: computer production comprises PLC selection and circuit board design and production; step two: software production; step three: computer installation; step four: parameter input; and step five: computer debugging comprises engine electronic throttle debugging, gearbox automatic control debugging and computer operation debugging. The universal computer has the advantages that the adopted technology is mature; the performance is reliable and stable; the anti-interference ability is strong; the function is rich; the expansibility is high; the use is convenient;the universal computer is easy to purchase; and the universal computer is produced by using the widely applied PLC manufactured by Siemens of Germany and additionally arranging a circuit board capable of completing special functions. The computer is enabled to have extremely high universality and better operation effects.

Description

technical field [0001] The invention relates to the control field of container flow loading and unloading machinery, in particular to a general-purpose computer for realizing the control of container flow loading and unloading machinery based on PLC. Background technique [0002] The current mainstream container empty container stacker mobile loading and unloading equipment such as kalmar, Fantuzzi, CVS, sis, SMV, PPM, haisite, linde, SANY, boos, etc. adopt their own technologies, and the control systems have their own advantages and disadvantages, and the control computers cannot be used universally. The following problems exist: [0003] 1. Expensive [0004] The computer boards used in the original car range from 30,000 to 40,000 to 70,000 to 80,000, and the control of the accelerator, gearbox, and attachments usually have their own independent control computers. One device is composed of multiple computers. , the price is very expensive. [0005] 2. Long procurement c...

AI Technical Summary

Problems solved by technology

[0003] 1. Expensive

[0004] The computer boards used in the original car range from 30,000 to 40,000 to 70,000 to 80,000, and the control of the accelerator, gearbox, and accessories usually have their own independent control computers. One device is composed of multiple computers. , very expensive

[0005] 2. Long procurement cycle

[0007] 3. Difficulty in spare parts storage

Leading to high inventory costs, it is not easy to reserve accessories

[0009] 4. Difficult maintenance

[0011] 5. Technology monopoly, functions cannot be expanded

[0012] Due to the technical blockade and monopoly of the manufacturer, the computer of container mobile handling machinery and equipment can only be connected to a specific dedicated computer, and without authorization, it is impossible to read and modify the internally stored data and data and computer programs, nor can it be based on actual conditions. Need to expand the required functions

[0013] For example, in 2005, when the equipment was inspected, the Special Inspection Office required that the equipment must have the function of overspeed warning and speed limit, which could not be realized due to the monopoly of the manufacturer

[0014] 6. Computer boards of different brands with the same function cannot be used interchangeably
