Remote support system and remote support method of belt weigher

Abstract

The invention relates to a remote support system and a remote support method of a belt weigher, and belongs to the technical field of the application of the Internet of Things. The remoter support system is composed of a client side and a management side which are connected in a communication mode through a network. The client side comprises a monitoring unit, a control unit, a client side receiving and dispatching unit and a man-machine conversation unit. The management side comprises a management side receiving and dispatching unit, a management server and an intelligent decision system which supports the management server. The control unit comprises a comparing device which is used for reading monitored data at fixed time and enabling comparison to be conducted, an inquiry unit which is used for inquiring corresponding solutions in a data base of the management server through the network and a conversation device which is used for obtaining the solutions through man-machine conversations with an operator by the aid of the man-machine conversation unit. According to the remote support system and the remote support method of the belt weigher, a manufacturer does not need to visit a site and can find problems timely, and the problems are solved automatically, or the manufacturer conducts remote guidance to general workers, corrects misoperation, finds out cheating phenomena and repairs failure equipment, and the perfectness ratio and the utilization ratio of the equipment are greatly improved.

Description

technical field [0001] The invention relates to a remote support system, in particular to a belt scale remote support system and a remote support method, belonging to the technical field of Internet of Things applications. Background technique [0002] Belt scales have the advantages of high efficiency and no need to increase transportation costs, so they are widely used. Its disadvantage is that it is easily affected by the environment, working conditions and belt effect, and it is difficult to maintain performance such as accuracy during verification or calibration for a long time. In order to maintain factory performance, strict daily monitoring and maintenance are usually required, and the result is that the after-sales service of belt scale manufacturers is very complicated. [0003] Retrieval finds that the Chinese patent whose notification number is CN87202731 discloses a "belt scale automatic corrector". This automatic calibrator can remotely control the loading or...

Problems solved by technology

But this kind of real-time monitoring device has a fatal flaw: that is, although the material transported by the same belt should obtain equal measurement data when passing through each weighing unit in theory, the measurement of the same dynamic weighing object by each weighing unit is limited. If the time is different, the measurement data obtained at the same time does not correspond to the same weighing object; without combining the historical status of the belt scale operation, errors will occur only based on the instantaneous data monitored in real time; moreover, the status data obtained by on-site monitoring The comparison is performed by the weighing instrument, and there are many factors that may affect the measurement results of the belt scale. Most of the functions of the relevant influencing factors have not yet been found.

[0005] In addition, the Chinese patent applications with publication numbers CN1896698 and CN101922960A respectively disclose the "Material Bar Code Superposition Method" and "Measurement / Validation Integrated System", which essentially integrate the above-mentioned two technical solutions of automatic hanging code and double scale frame, So there is the same flaw or problem
