Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.

The invention is further described with reference to the following drawings and specific examples, which are not intended to be limiting.

The first embodiment is as follows: the following describes the present embodiment with reference to fig. 1 and fig. 2, and the present embodiment describes an intelligent logistics safety auxiliary system based on bluetooth technology, which includes an upper computer 1, a cloud management platform 2, a first bluetooth low energy beacon sensor 3, and an intelligent mobile terminal 5;

the upper computer 1 makes a dangerous goods information webpage through webpage making software, compresses the URL, and sends the compressed URL to the cloud management platform 2;

The technical scheme adopted by the invention is as follows: the hardware device comprises a low-power Bluetooth beacon and an intelligent receiving device. The present invention uses samsung S5 as a representative of the Android system under test. In implementation, the Google online webpage design software and the URL compression software are used for shortening the website so as to meet the requirement of the low-power Bluetooth beacon. In a special area for storing dangerous goods, transportation workers can be exposed to danger when working nearby, the system can remind the workers when the workers approach, can also push dangerous goods information in real time, remind the workers to wear protective equipment and analyze industrial accidents which happen once. After a uniform resource of a certain specific area is constructed, a notification of relevant information can be issued. For example: "dangerous goods-flammable liquid (grade 3), please note" are present in the area. The website is distributed with the following two modes: one is for paid purchase of domain names and the other is for online compilation tools. After the webpage is published, the URL page needs to be pushed to a certain nearby determined range to play the roles of positioning and tracking.

The hardware devices include bluetooth low energy beacons, which are devices that broadcast bluetooth data packets, and a smartphone as a receiver. Since the Android smart phone and the Apple phone are different when receiving the notification, the Android smart phone and the Apple phone are classified into two types for explanation. In the use case, samsung S5 will be used as a representative of the Android smartphone for this test. On the other hand, in the implementation process, the software needs a Google website as a tool for designing the website of the software on line, and Google URL compression software is also used, so that the website can be shortened by the aid of the on-line tool, and the requirement of the low-power-consumption Bluetooth beacon is met.

Compared with the prior art, the invention has the beneficial effect that the low-power-consumption Bluetooth beacon is applied to the industrial environment for the first time. Theoretical research shows that the beacon can track the position and motion information of workers wearing the beacon in real time when being applied to a factory, so that the monitoring and reminding of the danger area where the workers approach are realized, and the purpose of enabling the workers to know the property of the logistics articles is achieved. Compared with the prior propaganda and education means, the method has more practical significance, plays the roles of prompting and warning from the aspect of visitation, and achieves the aim of improving the safety of workers.

In the implementation process, the low-power-consumption Bluetooth beacon adopts an Estimote Bluetooth beacon and pushes a message to a worker entering the area. When the Google website is used for designing the webpage, the website of the published webpage is compressed by a Google URL shortening device, and the beacon format is satisfied, and only the name of the URL is allowed to be less than 24 bits. The website is associated with the beacon, and then the playing power of the beacon is appropriately adjusted and the beacon is placed in the area, i.e., the whole system is realized.

In a complex manufacturing system, a person plays a significant role in various stages of design, manufacture, use, etc., which is not negligible or even decisive. Through intelligent recognition, positioning and tracking, the behavior of a person can be understood by the manufacturing system, the organic integration of the person and the system is realized, and the intelligent recognition, positioning and tracking system is of great importance for realizing the complete management and control of the manufacturing system and improving the production efficiency. In the aspects of human identification, positioning and tracking, domestic and foreign research mostly focuses on the aspect of positioning algorithm and improvement of universality thereof, and the positioning application environment is mostly in the social life field. For the positioning and tracking technology of the personnel in the vehicle compartment, the intelligent management of the personnel is realized by the information exchange and communication between the personnel and the intelligent terminal, and the real-time identification and tracking of the personnel in the manufacturing workshop with more complex working space environment and more rigorous working conditions is the basis of the human-machine-object cooperation.

The implementation process of the webpage design Bluetooth communication specifically comprises the following steps:

1. designing a plurality of visual interfaces: web page design typically uses the HTML language to design an entire web site and uses software to build sub-pages. Another approach is to edit the web page using online tools, most of which are visualized for editing. The latter is faster and more intuitive for designers, and does not require learning complex compiled languages. Thus, the present invention selects an online compilation tool. There are many choices for selecting online compilation tools, such as the WIX, SimpleWeb, and Google websites. The following factors are mainly considered: the difficulty of web page design operations, the manner in which the web pages are published, the need to purchase domain names, and the problems associated with server proxies. In contrast, the Google website was chosen as the platform for all web page designs. The main advantages are as follows: the webpage design operation on the Google website is a visual operation, and the layout of characters and pictures can be realized by drag and drop; when the website is released, the Google website is released on the basis of Google. Although the website has Google prefix, compared with the WIX and Simple websites, the Google website does not pay the cost; in contrast to websites compiled and designed in html language, the web sites published by Google websites do not need to consider the problem of proxy servers.

In the design of a web page, it is mainly divided into four parts: hazardous articles information module: the module is a first part of key information area, standardized dangerous product classification icons are displayed, and dangerous goods are briefly explained to prompt workers to approach the area. There are two methods for drawing and inserting dangerous goods figures or pictures: the first is to insert the picture directly by searching for keywords online: the advantage of this approach is that it can insert high definition images and most images are not watermarked. However, if the keywords are inaccurate, this will result in the insertion of an inappropriate picture. In this case, the keyword can only be changed for multiple searches. In addition, this approach does not meet the picture requirements if you use your own picture. The second method is to upload pictures or pictures made by you to the Google cloud hard disk and insert the pictures from the Google cloud hard disk when inserting the pictures. The advantage of this approach is that you can upload your own pictures.

The accident type module is a second part and is used for the reasons of related accidents of the industry, the module collects accident data of transported dangerous substances from the safety of pipelines and the harmful substances based on 10 years (2008-2017), has certain guiding significance for analyzing and summarizing the information of the industrial accidents caused by the dangerous goods, and comprises historical accident pictures of each type of dangerous goods and the reasons of corresponding accidents.

And the protective equipment module is a third part and is a confirmation area of the personal protective equipment, namely, the corresponding personal protective equipment is displayed in the form of a picture list according to the dangerous goods category stored in the area so that a worker can check the personal protective equipment by himself.

The dangerous goods interpretation module is a fourth part and is an explanatory paragraph about the dangerous goods stored in the area, such as definition of dangerous goods classification, a more accurate sub-classification under the classification and a common item of the dangerous goods classification. The hazardous material information module comprises a link of the module. According to past experience, operators in the area should be familiar with the nature of these hazardous materials when in normal contact, and therefore do not need to spend much time browsing. For workers who are not familiar with the properties of dangerous goods, the workers can quickly jump to the first part through the link of the first part to know detailed information, and the purpose of early warning is achieved. In designing the interface, you can preview the difference between the computer side page and the mobile phone, because the web page is mainly used for the smart phone and the smart watch, the layout and the interface can be adjusted in time.

2. And (4) publishing the webpage: the published web page in this embodiment is set for all to view, and since the URL format of the beacon is 24 characters at most, the URL in the previous step is longer than the 24 characters in the Google environment. Using the *** URL shortener, a short URL may be created, shared for tweets, or sent by email to a mailbox, compressing the URL to meet the format of the beacon-sent URL message.

3. Beacon management: logging in an Estimote Cloud, and managing the beacon before logging in after registration. If these beacons are not purchased on an individual's behalf, beacon rights must be surrendered in order to manage the user and buyer's beacons, and management of these beacons is typically identified by the user using APP, to the buyer through estimate. This method is very convenient, i.e. using APP named estimate to search and select the beacon that the user needs to use, which will prompt the owner of the beacon and prompt "declare beacon" or not, and select "yes" so that the mail will be automatically sent to the buyer. In the same way, the method can also be used for beacon sharing between users and then logging in the estimate Cloud.

On the estimate Cloud, you can manage all beacons of the account, and can monitor the battery power, working state (working or non-working), location and ambient environment information of the beacons at the Cloud. Finally, on the cloud, the time and location of people near the beacon can be recorded, and a statistical chart can be automatically generated to make a preliminary judgment on the working condition of the user for analyzing the beacon.

4. The system uses: for Android users and Apple users, a slight difference exists in the using process. First introduced here is how Android users use it. Android and Apple mobile phone users must open a Bluetooth function and a position function, and the Bluetooth function is an essential element because the positioning function is a condition for judging whether to enter a URL (uniform resource locator) push receiving range.

For the Android mobile phone, APP 'Physical Web' can be downloaded, and the APP can receive URL messages sent by beacons. When the screen is locked, the received message is pushed, and the pushed webpage information can be quickly checked through simple operation. Meanwhile, for the Android mobile phone, any application program cannot be installed, and only the URL push message can be received by opening the bluetooth function and the positioning function, which has great advantages for the application program, and means that a worker does not need to install any application program on the mobile phone or the smart watch to check the information of the personal protective equipment.

For a user using an Apple mobile phone or an Apple watch, under the condition of opening a Bluetooth function and a positioning function, an APP named Physical Web needs to be downloaded and installed through an APP Store, and only then can the URL information of a beacon be received. Furthermore, for Apple users, the application can search not only for URL push sent by the beacon, but also for low power bluetooth signals of all nearby devices, such as bluetooth signals of a computer.

5. And (3) system testing: the system can also detect the position information of the staff carrying the beacons in real time, and monitor the surrounding environment including the temperature and humidity and information of the environment through the fixed position beacons. Since the ID of each beacon is unique, this means that everyone's information can be accurately determined. Meanwhile, information of other beacons in the vicinity of each beacon may be counted in the cloud of the estimate, such as time, ID, total number of times the beacon is accessed within a specific time range, and other relevant information. The information has important value for managers, can definitely schedule work, reasonably optimize human resources and reduce idle scheduling and scheduling of working machines. The application of this system emphasizes the interaction between computational and physical processes. It monitors and controls the physical process by embedded computing and network technology, and adjusts the computing process by the feedback result of the physical process. A disadvantage of conventional approaches, such as the use of electronic tags, is that it can only collect point-in-time data over close distances or using other sensors, and real-time monitoring of physical behavior or the course of an event cannot be achieved. With respect to the data aspect, the data collected is intermittent and does not continuously monitor and control the physical process.

In terms of the effectiveness of the system, the system can operate normally in the experiment, and all pushed URLs can be searched in the mobile phone. The mobile phones are samsung S5, samsung notebook, zhongxing mobile phone, Apple 5S, Apple 7 and Apple X, and the mobile phones can receive URL pushing near the beacon. In the aspect of adaptability of the system, the system is mainly used for testing in a smart phone environment and can be used on other devices such as smart watches, tablet computers, smart televisions and the like, and the whole system is high in adaptability and not limited to a mobile phone terminal.

It is therefore to be understood that numerous modifications may be made to the illustrative embodiments and that other arrangements may be devised without departing from the spirit and scope of the present invention as defined by the appended claims.
