Fig. 1 is a structural diagram of a first embodiment of the intelligent control system for production conveying line of the present invention, which includes a switch 100 and a production conveying line control subsystem 200. The production delivery line control subsystem 200 includes a controller 210, a human-machine interface 220, a first motor 230, a second motor 240, a first sensor 250, and a second sensor 260, wherein the first motor 230 and the second motor 240 are connected to the controller 210 via a field bus, and the controller 210 and the human-machine interface 220 are connected to the switch 100 via a local area network.
It should be noted that the switch is not included in the production line control subsystem. The switch is used for carrying out the function of local area network data exchange. For example, when there are multiple production lines, multiple production line control subsystems are respectively constructed on the basis of each production line, data interaction is sometimes required between controllers of these subsystems, and at this time, the exchange receives and forwards the interactive data, thereby realizing the interaction of data of different production line control subsystems on the local area network. In addition, the controller 210 and the human-machine interface 220 are also connected with the switch 100 through the local area network, so that the controller 210 and the human-machine interface can also perform data interaction on the local area network, the reusability of the local area network is enhanced, an additional communication line does not need to be additionally arranged between the controller 210 and the human-machine interface, and the wiring amount and the wiring difficulty are effectively reduced.
The motor comprises a permanent magnet motor, a frequency converter, a built-in controller and a terminal group. Specifically, as shown in fig. 2, the first motor 230 includes a first motor permanent magnet motor 231, a first motor frequency converter 232, a first motor built-in controller 233, a first motor terminal group 234, and a first motor keyboard interface 235. As shown in fig. 3, the second motor 240 includes a second motor permanent magnet motor 241, a second motor frequency converter 242, a second motor built-in controller 243, a second motor terminal set 244 and a second motor keypad interface 245.
The motor can adopt an integrated permanent magnet synchronous motor. The integrated permanent magnet synchronous motor has the advantages that multiple functions such as signal transmission, power supply and logic processing are achieved through high integration performance, particularly, the motor is used as a node, and a control signal and a sensing signal are transmitted through a bus and are connected with a power supply in a near-line mode, so that the wiring amount and the wiring difficulty are reduced to a great extent. Meanwhile, a controller arranged in the motor can realize local processing of the sensing signals, and the data processing pressure of the controller is reduced.
The above-described function of the motor will be specifically described below with reference to the first embodiment.
When the production conveying line control subsystem comprises two or more motors, two adjacent motors in the production conveying line control subsystem are connected with each other, and the controller is connected with the motor closest to the controller. The characteristics that most motors are far away from the controller and the distance between the adjacent motors is fixed and short are considered, the two adjacent motors are connected with each other, and the motor closest to the controller is connected with the controller, so that the wiring amount and the wiring difficulty are reduced, and meanwhile, the communication between the motors and the controller can be realized.
Specifically, in this embodiment, the first motor 230 and the second motor 240 are two adjacent motors in the production line control subsystem 200, the first motor 230 and the second motor 240 are connected to each other, the distance between the second motor 240 and the controller 210 is the closest, and the second motor 240 and the controller 210 are connected to each other. Because the first motor 230 is far away from the controller 210, and the distance between the adjacent first motor 230 and the second motor 240 is fixed and short, the first motor 230 and the second motor 240 are connected with each other, and then the second motor 240 closest to the controller is connected with the controller 210, the wiring amount and the wiring difficulty can be effectively reduced.
The terminal set of the motor is a plurality of terminal subsets for connecting other devices. Therefore, other equipment can transmit signals through the motor to obtain a control power supply. For example, the following devices can be connected:
the terminal group of the motor is connected with the field bus and the control power supply;
sensors in the production run control subsystem are connected to the terminal sets of adjacent motors.
Specifically, as shown in fig. 4, the first motor terminal group 234 of the first motor 230 of the present embodiment includes four connection terminals, which are a high level terminal, a low level terminal, a ground reference terminal and a sensing signal terminal.

The motor may be connected to a control power supply via a ground terminal to provide power to the sensor. Through the sensing signal terminal, the sensing signal can be transmitted to the motor built-in controller for processing, or transmitted to the controller 210 for processing through the field bus.
The terminal sets of the second motor 240 and their connection to other devices is similar to the first motor 230 described above.
In addition to the terminal sets, the motor also has a keypad interface. In addition, the intelligent control system for the production conveying line can also comprise a keyboard, and the keyboard is connected with a keyboard interface of the motor.
The keyboard interface may be of the type RJ45 interface. A user can set the operation type of the built-in controller of the motor and set the operation parameters of the motor through a keyboard. It should be noted that although each motor has a keyboard interface, for example, in the first embodiment, the first motor 230 includes the first motor keyboard interface 235 and the second motor 240 includes the second motor keyboard interface 245, a keyboard need not be provided for each motor. The whole intelligent control system for the production conveying line only needs to comprise one keyboard, and when the operation type of a built-in controller is required to be set for a certain motor or the operation parameters of the motor, the keyboard can be used for operation only by inserting the keyboard into a keyboard interface of any one motor connected through a bus.
The frequency converter of the motor can also be connected with the driving power supply of the motor nearby. Because the converter is directly integrated in the motor, the motor need not to independently wiring to the control electric cabinet in order to connect drive power supply again. Any 380V driving power supply near the motor can be connected. Specifically to the present embodiment, the first motor 230 may be connected to a nearby driving power source through the first motor inverter 232, and the second motor 240 may be connected to a nearby driving power source through the second motor inverter 242. Like this, need not to work a telephone switchboard to a fixed control electricity cabinet and obtain the power, reduced the wiring volume and the wiring degree of difficulty.
The sensors are photoelectric sensors that detect the position of the production components on the production line and transmit the position to the controller 210 for further processing and control. Specifically, in the present embodiment, the first sensor 250 and the second sensor 260 are respectively installed at the starting positions of two adjacent sections of the same production conveying line, when the production parts sequentially pass through the starting positions of the two end sections, the sensors transmit signals of the production parts to the controller 210, and the controller 210 controls the start and stop of the relevant motor according to a preset control method.

It should be noted that the number of the production line control subsystems is determined according to the number of the production lines, that is, how many production lines are constructed. Each production conveying line control subsystem is provided with a controller and a human-computer interface to control the production conveying line, and all the controllers and the human-computer interfaces are connected with the switch through the local area network, so that data interaction among the different production conveying line control subsystems is realized, and any controller can read the running conditions of all the production conveying lines. Specifically, in this embodiment, the controller 210 and the human-machine interface 220 of the production conveyor line control subsystem 200, and the second controller 310 and the second human-machine interface 320 of the second production conveyor line control subsystem 300 are connected to the switch 100 through the local area network and perform data interaction, so that the controller 210 of the production conveyor line control subsystem 200 can read the production data and the equipment information of the production conveyor line controlled by the second production conveyor line control subsystem 300, and the second controller 310 of the second production conveyor line control subsystem 300 can also read the production data and the equipment information of the production conveyor line controlled by the production conveyor line control subsystem 200, thereby solving the problem of less interaction data among different production conveyor lines in the prior art.

Specifically, in this embodiment, the intelligent control system for production conveying line further includes a server 400, a personal computer terminal 500, and an internet of things module 600, and all are connected to the switch 100 through a local area network. Since the controller 210 and the second controller 310 are also connected to the switch 100 through the lan, the production data and the equipment information generated by the controller 210 and the second controller 310 can be transmitted to the server 400 through the switch, and the production data and the equipment information can be stored and analyzed for a long time. The user can also access the server 400 through the personal computer terminal 500 to monitor the operation condition of the production transmission line in real time. If the user is not in the factory, the server 400 can be accessed by mobile communication equipment such as a mobile phone and a tablet computer through the internet of things module 600, and the operation condition of the production conveying line can be remotely monitored.
