[0024] In the technical scheme of the utility model, through installing one integrated electric box 2 on each independent conveying equipment 1, the electric box is shipped together with the equipment, when installing on site, only need to connect power supply and communication line, solve the problem of low efficiency, poor expansibility and lack of standardization in traditional centralized wiring, the system adopts distributed control architecture, all equipment carries out efficient communication and data transmission with PLC controller through integrated electric box 2, through ASI and Profinet bus, the system can realize quick and stable data exchange, ensure the coordinated work between each equipment, improve the overall work efficiency and accuracy of production line.
[0025] Specifically, two kinds of industrial fieldbus protocol ASI and Profinet construct layered communication network, connect dispersed electrical equipment into a cooperative distributed control system, ASI bus is used to connect signal acquisition module in single equipment electric box, input and output (I / O) signal of each equipment is summarized to distributed node, Profinet bus is used as main control network, connects PLC controller and integrated electric box 2 of each equipment, realizes centralized instruction issuing and data monitoring, uses bus technology to replace traditional centralized hardwiring, solves the problem of long line body, wiring difficulty and poor expansibility.
[0026] Wherein, drive controller 3 adopts frequency converter or servo driver, frequency converter or servo driver is connected with motor of independent conveying equipment 1, to provide smooth drive control, ensure the efficient operation of equipment.Signal acquisition module 4 is ASI module, supports the localization processing of integrated electric box 2 input and output signal, can real-time feedback the running state of equipment, ensure that the problem point can be quickly located when fault occurs, improve the maintenance efficiency of system, all electrical materials used in single equipment are installed in the table top, input and output signal and motor line of single equipment are all connected to integrated electric box 2 inside the table top.
[0027] As shown in Figure 1 Integrated electric box 2 and independent conveying equipment 1 are integrated from factory; before leaving factory, complete the installation, debugging and function test of all electrical materials inside the equipment, the parameters of each module inside integrated electric box 2 have been pre-set according to the standard operation condition of equipment, after the equipment reaches customer site, only need to connect external power and communication cable, can be quickly put into use, greatly shorten the installation cycle of customer site.
[0028] As shown in Figure 1As shown, the integrated electrical box 2 also includes an automatic fault diagnosis module inside. The PLC controller 6 has intelligent fault diagnosis and early warning functions. By monitoring the data transmitted on the ASI and Profinet bus in real time, combining the preset fault diagnosis model, it can quickly identify abnormal signals in the system, accurately locate the fault point of the independent conveying equipment 1 and its corresponding integrated electrical box 2, and timely send warning information, greatly improving the maintainability and reliability of the system.
