Description
Technical Field
The invention relates to the field of motion control, in particular to a control system of an automatic electroplating line vehicle.
Background
Industrial control computers are industrial control computers specially used in the industry, and industrial tablet computers are more concerned about stability in different environments, such as beverage production line control, automobile production line control and the like, and are required to be stable in severe environments, such as dust prevention, water prevention, corrosion prevention, static prevention and the like. The industrial computer product has the characteristics of firmness, shock resistance, moisture resistance, dust resistance, high temperature resistance, multiple slots, easy expansion and the like. Is the best hardware platform for various other applications in the fields of industrial control, traffic control, environmental control and automation.
The control system of the current automatic plating line is basically formed by adopting a PLC and a personal computer. The PLC is used for controlling the running of the overhead travelling crane and the current of the rectifier, and the personal computer is used as a monitoring system. Due to the limitation of the memory area of the PLC, a control system using the PLC generally can only retain 3 user programs. At present, electroplating products with various specifications are produced in an electroplating production workshop of a PCB factory, so that 6-8 sets or even more user programs are usually required. Therefore, when user programs other than 3 of the PLC are needed, the pre-programmed programs need to be downloaded to the PLC, the operation of replacing the programs is time-consuming and labor-consuming, and the effective working time of the electroplating production line is wasted due to the fact that the currently running programs need to be stopped during program switching. The switching of different process sequences requires approximately 1 or more hours to make the slot femto adjustment.
The plating line control system developed by our company adopts an industrial personal computer to replace the original system of PLC and personal computer, and the plating line control system
The system is written in C + + voice. Because the user programs on the industrial control computer are stored in the hard disk of the computer, an infinite number of user programs can be theoretically stored. Therefore, the time for replacing the user program is greatly reduced, the system can automatically carry out the sorting adjustment of the flying bar when the user program is replaced, and the utilization rate of the plating line is greatly improved. The system is deeply used by all users.

Detailed Description
The technical solutions of the present invention will be described clearly and completely below, and it is obvious that the description is only a part of the embodiments of the present invention, not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention provides a technical scheme that: the invention relates to an automatic electroplating line vehicle control system, which comprises an industrial personal computer 1, wherein the industrial personal computer 1 comprises a control cabinet 11 and a human-computer interaction component 12, the human-computer interaction component 12 is fixedly connected to the control cabinet 11, and the automatic electroplating line vehicle control system is characterized in that: five ISA slots 13 are formed in the control cabinet 11, an IO terminal board 14 is fixedly connected in each ISA slot 13, two serial ports 15 are further formed in the control cabinet 11, and an RS232-485 converter 16 is fixedly connected to each serial port 15.
The IO terminal board 14 is provided with sixteen-way output and sixteen-way input isolation ISA control card.
The IO terminal block 14 is provided with input points directly connected to respective input signals like a position of a detection crown block.
And RC filter plates are fixedly installed at the connection positions of the input points arranged on the IO terminal board 14 and each input signal at the position of the crown block.
And the output end of the IO terminal board is fixedly connected with a frequency converter 19 for controlling the forward and reverse rotation and speed control switching, starting and stopping of the crown block.
It should be noted that: the basic architecture of the plating line control system is an industrial computer + ISA industrial IO plug-in card, and all input and output points adopt 16-path input and 16-path output IO plug-in cards. The rectifier adopts a digital high-frequency switch rectifier produced by me company, and the rectifier is provided with an RS485 digital communication interface. The industrial personal computer is provided with 3 serial ports, each serial port is connected with an RS232-485 converter, and each 485 port can be connected with 32 rectifiers, so that the system can be connected with and control 96 rectifiers at most.
16 paths of input and 16 paths of output isolation ISA control cards are respectively inserted into 5 ISA slots of the industrial computer, so that the system has 80 input points and 80 output points. The input points are directly connected to respective input signals like the position of the detected crown block. All sensors for detecting the position of the crown block are additionally provided with RC filter plates at the input ends, so that the electromagnetic interference on the site can be eliminated. To prevent slot count errors. The forward and reverse rotation and speed control switching signals of the crown block frequency converter are directly connected to the output point of the IO card through the start and stop signals. Connecting current greater than 200ma or AC220V output devices would need to be done through an intermediate relay.
The counting of the slot position of the crown block is carried out by adopting an increment counting mode, and counting filtering processing is arranged in the counting of the slot position, so that the counting error of the slot position caused by electromagnetic interference can be filtered out. And each slot position is provided with a parity detection bit for verifying whether the current position of the overhead travelling crane is correct or not.
The horizontal running speed of the crown block has 5 sections of running speeds. The lowest speed, the medium speed, the high speed, the ultra-high speed and the highest speed are respectively.
The final positioning adopts the lowest speed and can set a delay stop function, so that the stop position of the crown block can be ensured to be positioned at the center of the slot position, and the phenomenon of falling of the flying bar when the flying bar is put down and lifted is prevented. The switching of each speed is carried out according to the slot position number between the current slot position of the crown block and the destination slot position.
2 RS232 interfaces on the computer convert the communication signals into 485 format current signals through RS232-485 converters. Thus, 32 rectifiers can be connected to each 485 interface. Therefore, the setting current, the switching signal, the actual current value and the actual voltage value of the rectifier are all completed through communication.
