The USB communication device further comprises a third communication interface 10, the third communication chip 5 is connected with the USB/485 communication converter 9 through the third communication interface 10, and the third communication interface 10 is an RS485 interface.

The intelligent control system further comprises a second communication interface 15, and the fourth communication chip 13 and the fifth communication chip 14 are both connected with the main control panel 2 through the second communication interface 15, so that communication is facilitated.

The novel device also comprises a shell 16, wherein the first controller and the second controller are arranged on the same PCB and are integrated in the shell 16, so that the space is reduced, the integration is convenient, and in order to reduce the number of the controllers, the first controller and the second controller are integrated together, so that a novel device with double control chips and interface terminals is manufactured. The integrated new device is connected with the communication ports of the other three frequency converters and the main control panel through the communication port of the first control chip 6 to complete the response function of the two hot roller frequency converters; the second control chip 12 completes the response function of the two temperature controllers. Through the experiment, two hot-roller frequency converters and two temperature controllers are replaced to new device and main control panel communication is normal, and every spinning production position just can dismantle two frequency converters and two temperature controllers like this, and 16 positions are totally done to two production lines, has made 16 new devices, replaces 32 frequency converters and 32 temperature controllers totally, and the steady operation always after reforming transform.

A set of program simulating the response of the two hot roller frequency converters to the main control board 2 is written, the purpose is to replace the two hot roller frequency converters with a first controller, the communication flow of the first controller and the main control board 2 is shown as the attached figure 5, and the specific communication process is as follows: after the first controller is electrified, serial port communication, interruption, flag bit initialization and the like are firstly carried out, then the serial port interruption subprogram is utilized to receive information from the main control board, and corresponding flag bits are set according to the first byte code of each group of information. And the main program continuously feeds the watchdog, simultaneously replies specific information or frequency signals to the main control board according to the zone bits, and clears the corresponding zone bits after the information is sent. When information is transmitted, each byte is required to be subjected to odd check, hexadecimal numbers corresponding to each byte in a group of transmitted bytes are accumulated, then two numbers in the accumulated sum are subjected to ASCII code conversion to obtain two bytes, the two bytes are used as check codes of the group of transmitted bytes and are also transmitted to the main control board 2 according to the sequence, and therefore continuous communication can be carried out with the main control board 2.

And designing a second controller and compiling a temperature controller response program, fixing the temperature value of the hot roller to be 25 ℃ in the program, and then replacing the two hot roller temperature controllers by the second controller to be connected and communicated with the main control panel 2. The communication flow between the second controller and the main control board 2 is shown in FIG. 3, which is similar to the communication flow between the first controller and the main control board 2, but the communication baud rate, the content and the format of the transmission to the main control board 2 are different from the program in the first controller, wherein the temperature value of the hot roller is fixed at 25 ℃, and thus two temperature measuring elements are omitted. Specifically, the different communication baud rates mean that the baud rate in the response program of the frequency converter is 19200, and the baud rate in the response program of the temperature controller is 9600; the content and the byte number sent by each group are different, the data corresponding to the frequency converter is a frequency value (after replacement, the frequency is always zero, the frequency converter does not need to be started because the hot rollers are all removed), the byte number is 9, and the communication value is 5 bytes; the data group corresponding to the temperature controller is a temperature value, the number of bytes is 6, and the contact value is 4 bytes.

The production line in the prior art uses imported special frequency converters and temperature controllers, the price is high, and each frequency converter needs about 2 ten thousand RMB. After the transformation, spare parts do not need to be purchased for the hot roller frequency converters and the temperature controllers of the two lines, and the replaced 32 frequency converters and 32 temperature controllers can be used as spare parts of the same type of frequency converters and temperature controllers in other production lines, so that the expense of the spare parts is greatly saved for companies.

As can be seen from figure 1, each section of the production line comprises a traversing roll and two spindle rolls, each driven by a dedicated frequency converter, the operating frequency of which is determined by the process set point and the speed feedback from the respective rolls. According to the reflection of production process personnel: in the prior production process, the speed of a certain roller possibly causes the abnormal quality of a product, but the speed value of each roller is not recorded and stored on a process computer, so that the corresponding relation between the problem product and the abnormal speed of the running roller cannot be verified.

As can be seen from fig. 2, the first communication interface 11 of the new device is connected to the communication lines of the traversing and spindle frequency converters, which can be programmed to receive the operating frequency signals when these three frequency converters send these signals to the main control board 2. The communication program of the analog frequency converter is modified, so that the communication program can replace the two hot roller frequency converters to communicate with the main control panel, and the frequency signals of the transverse and spindle frequency converters can be acquired when the transverse and spindle frequency converters send information to the main control panel 2, and the signals are temporarily stored in the first control chip 6. In addition, we also improve 16 new devices, each new device is added with a communication chip, and the chip is connected with the second communication terminal of the first control chip 6 to form a third communication interface 10 in the new device. Finally, the third communication interfaces 10 of 16 new devices are connected by a network cable and are connected with a process setting computer 1 after passing through a USB/485 converter; according to the requirements of production workshop, we newly develop a monitoring and recording program in the process setting computer 1, which can read and display the transverse moving and spindle frequency-changer frequency signals temporarily stored in 16 new devices, and record and store these signals in the form of curve. Because the frequency signal of the frequency converter can indirectly reflect the speed of the controlled roller, when the product quality problem occurs, whether the problem is caused by the abnormal speed of the roller can be determined by checking the corresponding frequency curve, thereby improving the solving efficiency of the problem product; in the normal production process, one spindle roller of each winding head which is winding the spinning cake moves, and the frequency of a corresponding frequency converter is not zero; the other roll is stopped and the corresponding frequency converter frequency is zero. When the winding process reaches the preset full-winding weight time, the two spindle rollers are automatically switched, namely the roller which is stopped originally moves and the roller which is moved originally stops. If a fault occurs in the winding process, the two spindle rollers can be manually switched. The switching time of the two rollers is recorded by the current time of a computer, and the time difference value of the two switching times is compared with the preset winding weight time of each grade, so that whether the spinning cakes produced in each batch are full rolls, medium rolls, small rolls or waste products can be judged. This is very beneficial to the management of the production in the plant.

The control chip is a single chip device, and the communication chip is a communication conversion device.

Specifically, as shown in fig. 4, the first controller and the second controller are both controllers with two communication serial ports and control terminals, the first communication interface 11 and the second communication interface 15 are both RS422 communication ports, the models of the first control chip 6 and the second control chip 12 are both IAP15F2k61S2, and the models of the first communication chip 7, the second communication chip 8, the third communication chip 5, the fourth communication chip 13 and the fifth communication chip 14 are all ADM 2483. That is, pin 3 of the communication chip ADM2483 is a receiving pin, pin 6 is a transmitting pin, pins 12 and 13 are differential input/output pins, pin 4 is a receiving enable pin, and pin 5 is a transmitting enable pin. The 4 pins and the 5 pins of the first, second, fourth and fifth communication chips are all in short circuit, wherein the enable pins of the second and fifth sending chips are connected with high level, and the enable pins of the first and fourth receiving chips are connected with low level. Pins 4 and 5 of the third communication chip are controlled by a program through pins 1 and 2 of the first control chip respectively; a 18/19 pin of a first control chip IAP15F2K61S2 is a receiving/sending pin of a communication serial port 1, and a 4/5 pin is a receiving/sending pin of a communication serial port 2; the first controller and the second controller are both arranged on a PCB board and protected by a plastic shell.

As shown in fig. 5, the first control chip receives the information of the main control board and the process computer and the frequency of the transverse and spindle frequency converters through two interrupt subroutines of the serial ports 1 and 2, marks corresponding flag bits or stores the frequency of the corresponding frequency converters, and sends the information to the main control board and the process computer through the serial ports 1 and 2 in the main routine.

Specifically, the principle of the invention is that a first controller is arranged for simulating communication between the frequency converter and the main control board 2, and a second controller is arranged for simulating communication between the temperature controller and the main control board 2, so that the frequency converter and the temperature controller can be removed, production is facilitated, and the frequency converter and the temperature controller are reduced in use, so that the electrical fault rate can be reduced, and the influence of electrical fault on production is reduced; the maintenance work of the front spinning electric instrument is facilitated: on one hand, the maintenance workload of the electrical instrument can be reduced when the electrical failure rate is reduced; on the other hand, because of the addition of the standby frequency converter and the temperature controller, the electrical instrument technicians can have sufficient time to maintain the fault electrical appliance, thereby improving the maintenance quality.

On the basis of the above-described aspects, if various changes or modifications to the present invention are made without departing from the spirit and scope of the present invention, it is intended that the present invention also include these changes and modifications if they fall within the scope of the claims and the equivalent technical scope of the present invention.
