Remote control system and remote control method used for material sorting equipment

Abstract

The invention provides a remote control system used for material sorting equipment. The remote control system comprises at least one material sorting equipment, a local area network control terminal, an internet control terminal, a data service center and a VPN (virtual private network) server, wherein the material sorting equipment and the local area network control terminal are arranged on a client site, the internet control terminal, the data service center and the VPN server are arranged at an after-sale service center, and each of the local area network control terminal and the internet control terminal comprises a PC (personal computer) and a mobile terminal. The local area network control terminal and the material sorting equipment form a local area network and access to the internet via a gateway and a firewall, and the internet control terminal, the data service center and the VPN server access to the internet. The remote control system has the advantages that networking and multi-terminal control of the material sorting equipment in the local area network are realized, no delay in network operation is guaranteed by the aid of the VNC (virtual network computer) technology, NAT (network address translation) traversal is realized while safety and high efficiency of transmission on the internet are guaranteed by the aid of the VPN technology, processing capacity of an entire production line is improved, and maximization of the overall task performance of all the material sorting equipment is guaranteed.

Description

technical field [0001] The invention relates to the technical field of remote control of material sorting equipment, in particular to a remote control system and method for material sorting equipment. [0002] Background technique [0003] At present, the following problems exist in the use of material sorting equipment: [0004] (1) In order to improve the efficiency of material sorting, there are more and more cases where multiple (such as 3 to 10) material sorting equipment are deployed on the same production line to work at the same time, because the internal optical conditions of each material sorting equipment will have subtle differences , there are many sorting schemes for different materials, therefore, it is necessary to solve the problem of collaborative work between multiple material sorting equipment; [0005] (2) Usually one material sorting equipment needs to be equipped with an operator, and the operator controls the material sorting equipment through the h...

AI Technical Summary

Problems solved by technology

[0006] (3) The operation of the material sorting equipment is relatively professional. When the material sorting equipment on the customer's site fails or has operational problems, it is often difficult for the customer to solve it independently. If the after-sales service personnel cannot arrive at the customer's site in the first time, it will seriously affect the customer's production schedule;

[0007] (4) When the customer needs to sort new material varieties, effective algorithm support must be provided. If the material sorting equipment at the customer site cannot be effectively remotely controlled, the after-sales service personnel of the equipment manufacturer must rush to the customer site. According to the new Feature upgrade algorithm for material varieties;

[0009] (6) When the material sorting equipment is debugged before leaving the factory and at the customer's site, it is usually only possible to connect the camera through an oscilloscope or an LCD screen. When debugging multi-channel parallel acquisition cameras, it is cumbersome to connect and debug equipment. In a limited space, it is operated at the same time It is difficult to operate the camera while observing the signal on the debugging device

[0011] (1) Only one material sorting device corresponds to one control PC, and centralized control of multiple material sorting devices is not considered, and unified management of all devices that can be connected to the Internet is not considered, nor is there a wireless network-based mobile Terminal access scheme;

[0012] (2) The control of the material sorting equipment in the production line can only control the basic operations such as switching the material and controlling the feeding amount, and cannot obtain the complete working information of the material sorting equipment (including signals, images, algorithm parameters, real-time status , logs, etc.), unable to log in to remote devices to achieve real-time online control;

[0013] (3) It does not provide a complete remote control solution from the local area network to the Internet, it can only work under specific network conditions, it is not universal, and it cannot provide a network foundation for various value-added services;

[0014] (4) The way the material sorting equipment on the customer site is connected to the Internet is not considered, and the problem of how to pass through the firewall when remotely controlling the material sorting equipment is not solved
