Description
Technical Field
The invention belongs to the technical field of mobile terminals, and particularly relates to an intelligent waste mobile terminal identification method based on recovery equipment.
Background
Mobile terminals such as smart phones and tablets become an indispensable part of the lives of residents in the information age, and the replacement frequency of the mobile terminals is gradually increased due to the innovation of the technology. At present, a complete recovery system is not established in China, and the recovery rate of the normal channel of the waste mobile terminal is only about 1 percent[1]. According to statistics, the production and sale of mobile phones in China have been already carried out since 2004First position in the world[2](ii) a In 2018 years only, the total goods output of the mobile phones in domestic markets is 4.14 hundred million, the rejected waste mobile phones reach 3 hundred million, but the recovery rate of a regular channel is less than 5 percent[3,4]. The waste mobile terminals contain a large amount of precious metals, and if the precious metals are not recovered in time or the recovery means is unreasonable, resource loss and environmental pollution can be caused. Taking a waste mobile phone as an example, at present, four recycling ways are mainly used in China[5]: the method comprises the steps of individual mobile vendor home recycling, spontaneous recycling of manufacturers and operation mobile vendors, regular recycling of enterprises and direct abandonment of the enterprises as household garbage. The unreasonable recovery of the waste mobile phones aggravates the environmental deterioration and causes serious harm to the global environment.
In recent years, a new recycling model of "internet + recycling" has gradually replaced individual vendors and producers to recycle spontaneously. In the recovery modes, how to utilize intelligent recovery equipment to complete the recovery of the waste mobile terminal becomes a key link. At present, the waste mobile terminal identification modes adopted by different types of recovery equipment mainly include the following four modes: (1) and identifying based on the appearance image of the waste mobile terminal. Such as, document [6]]Identifying the model and brand of the waste mobile phone through an image technology; document [7]]And a scanning device is added on the basis of image sensing, and the recognition rate is improved by utilizing the scanned image on the back of the mobile phone. At present, the image recognition technology is still in a development stage in the aspect of recognition application of the waste mobile terminal, the success rate is low, and recovery equipment for recognizing the waste mobile terminal only by means of images does not exist. How to improve the image recognition efficiency based on multi-view information of the waste mobile terminal is still a difficult problem which needs to be solved urgently at the present stage; (2) and identifying the waste mobile terminal based on the IMEI code of the mobile phone. Document [8]A hand-held IMEI code recognizer is designed, and IMEI codes are obtained in an input or scanning mode and are matched with information stored in a database; if the IMEI code cannot be matched, the identifier acquires the IMEI code by accessing the Internet. The limitations of this approach are: the mobile terminal adopting other protocols such as CDMA and the like adopts MEID code for identification and does not have IMEI code[9](ii) a (3) The mobile phone is controlled by a mechanical hand in the independent recycling box to complete operations such as shooting, touch control and the like for identification. Document [10]]Put forward through the control boxThe manipulator takes pictures by using front and rear cameras of the waste mobile phone to check the functions of the camera of the mobile phone, and performs touch and press operations on the mobile phone to check the touch sensitivity of the mobile phone. However, the method can only detect part of hardware of the mobile phone; (4) and connecting the waste mobile terminal through a data line to obtain the identification information. This is currently the most widely used identification. Document [11]And connecting the waste mobile terminal with the identification device through a USB data line, and detecting the matching of the built-in configuration parameters of the mobile phone and the existing information in the database to complete the identification. But this method cannot identify the old and useless mobile terminal whose interface has been damaged. In addition, the old and useless mobile terminals which are not contained in the database cannot be identified. In addition, if the internal configuration of the old and useless mobile terminal is modified, the method can also identify errors. Further, document [12]]The information such as the brand, the model and the like of the waste mobile terminal is obtained by combining the image identification with the data line connection mode, but the possible difference of the identification information in the local/remote database of the recovery equipment and the situations that the waste mobile terminal cannot be started and the interface is abnormal and the like are not considered.
Disclosure of Invention
The method aims at the problem that the conventional recycling equipment for the urban renewable resources mostly adopts a data line connection mode to acquire the internal information of the waste mobile terminal to be recycled for identification, but the mode cannot identify the waste mobile terminal which cannot be started or has a damaged data interface. In addition, the identification method of the waste mobile terminal based on the image, the IMEI code and other modes has the problems of poor reliability, limited coverage types and the like, and particularly, effective recovery of the waste mobile terminal is difficult to realize when the network connection of recovery equipment is abnormal. In order to solve the problems, the invention provides a waste mobile terminal intelligent identification method based on recovery equipment, which comprises the steps of firstly, adopting a starting detection and front image acquisition module, carrying out starting state detection by the cooperation of a delivery user of a waste mobile terminal, and acquiring front images of the waste mobile terminal before and after starting or front images of the waste mobile terminal which cannot be started; then, an internal information acquisition module is adopted to detect the interface state of the waste mobile terminal through a connection data line, and a camera device is used to acquire a back image of the waste mobile terminal placed at the detection position of the recovery equipment; then, an interface detection and back image acquisition module is adopted to acquire the authority and extract information of the waste mobile terminal with a normal interface; and finally, detecting the network state of the recovery equipment by adopting a recovery equipment network state detection module and an intelligent identification module based on multi-source characteristics, and fusing the multi-source information to respectively perform intelligent identification on the waste mobile terminal in normal and abnormal modes of the network state of the recovery equipment.
