The present invention relates generally to the fields of logistics, and, monitoring technology for shared recyclable logistics tools.
A recyclable logistics tool is a cargo carrier that can be reused. A more general model is purchased by the user and used by himself. However, most users do not always use recyclable logistics tool. The recyclable logistics tool can only be stacked in the warehouse, which results in storage costs, on the one hand, the rate of utilization of recyclable logistics tool is also relatively low during the period of non-use.
To solve this problem, the applicant of this invention has promoted a business model of shared recyclable logistics tool, wherein, one way is shared leasing, i.e., An operator purchases recyclable logistics tools and leases the recyclable logistics tools to multiple users. A user may obtain recyclable logistics tools from the operator when he needs to use it. The user may return the recyclable logistics tool to the operator or directly transfer to the next user who needs to use when the user does not use it. As a result, this dramatically reduces the user's cost. Another way is to share for using, i.e., A user purchases recyclable logistics tools by himself. He may lease the recyclable logistics tools via the operator to other users when the user does not use the recyclable logistics tools. This not only saves costs, but also achieves the profits for the users.
From the perspective of the entire society, these recyclable logistics tools sharing methods have significantly improved the utilization rate of recyclable logistics tools and dramatically reduced the cost for users. However, the way of sharing also notably increases the difficulties of anti-burglary of recyclable logistics tools. Because recyclable logistics tools are constantly being used by different users, the difficulties of management have dramatically increased. The geographical scope of their use is undetermined, the way of using is variable, the logistics path is also undetermined, how to know if recyclable logistics tools are being used normally or are likely to have been stolen becomes a big problem. If the problem of anti-burglary cannot be solved well, it will dramatically restrict the implementation of the sharing mode of recyclable logistics tools.
The purpose of the present invention is to provide a monitoring method and system for shared recyclable logistics tools, which can accurately and promptly find recyclable logistics tools that may be stolen.

However, those of ordinary skill in the art can understand that even without these technical details and various changes and modifications based on the following embodiments, the technical solution claimed in this invention can be implemented.
Explanation of Some Concepts:
The “server” indicates that a computer system in the network that can provide certain services to other machines. The objects of server services are usually referred to as clients. The server and the client can be connected through wired or wireless communication. In the embodiments of the present invention, the server may be only one computer, or a logical server system composed of multiple computers with different functions, or a computer system composed of a computer and an external device such as an external storage device. It may also be a computer cluster or a cloud server or the like.
The “recyclable logistics tool” indicates that reusable logistics tools, which can be loaded with solid or liquid substances, and can also be packed with packed gaseous substances. Typically, after the empty state of recyclable logistics tool is transported to the shipper, the goods are loaded in it, and then the full state of the recyclable logistics tool is transported to the receiver, the goods in it are unloaded, and the recyclable logistics tool which the empty state is restored may be reused again.
The “correspondence relationship” indicates that the correspondence relationship between two or more data, which is usually stored in a storage device or storage device. The storage device or storage device may be a database, file, hard disk, memory, etc.
The “camping”: it indicates that recyclable logistics tools appear in a small area for a long time, and there is basically no obvious movement, or the position within a certain period of time are concentrated in a certain radius area. Certainly, a reasonable positioning error should be considered according to different positioning methods when judging.
The “sharing” indicates that the sharing and mixed use of recyclable logistics tools. It may be the sharing among different enterprises through the leasing model, but it may also be the sharing (mixed use) of recyclable logistics tools through respective procurement. Because the recyclable logistics tool purchased by everyone is standardized, it can be mixed used among enterprises.
The “time-shared” indicates that the same recyclable logistics tool is used by different users at different times, i.e., the right to use the recyclable logistics tool is time-multiplexed.
The “GPS” indicates that Global Position System.
Some of the innovations of this invention are briefly shown below:
It is difficult to judge a shared recyclable logistics tool was stolen and to give a timely alarm. The first difficulty is that the recyclable logistics tool is shared and used by multiple users in a time-shared manner, and its range of movement may be relatively large. It is difficult to judge whether it is stolen based on the positioning information. The second difficulty is that it is difficult to judge whether the recyclable logistics tool is on a reasonable path. On one hand, due to traffic jams and other reasons, logistics companies may flexibly choose multiple transport paths for transportation. The choice of transport path is often beyond the control of user of the recyclable logistics tool. Even if the user knows the current location of the recyclable logistics tool, it is difficult to tell whether the recyclable logistics tool was during normal shipping or has been stolen. On the other hand, for the management party of the recyclable logistics tool, when the recyclable logistics tool is leased to the user thereafter, the management party may not be able to promptly know the user's specific destination (the user's transportation plan is not obliged to report to the management party promptly), so it is even impossible to estimate a reasonable path.
A valid area set can be set for each possible leasing user in advance by the server of the management party. After positioning the recyclable logistics tool, find the current user of the recyclable logistics tool, and then find the valid area set corresponding to the current user, and then determine whether the recyclable logistics tool is in the valid area set. If it is in the valid area set, it is considered that the recyclable logistics device is not currently stolen. If it is not in the valid area set, further judge whether the recyclable logistics tool camps outside the valid area for a long time (i.e., the camping duration exceeds a predetermined threshold). If so, the recyclable logistics device is considered to have the possibility of being stolen, and the user or the operator is alerted by the server of the management party. If it is still in a moving state although it is outside the valid area, continue to observe and do not report the alarm temporarily. Through this technical solution, even if the recyclable logistics tool is rented by multiple different users within a certain period of time (that is, for the same recyclable logistics tool, there are different sets of valid areas in different periods; optionally, the same user may also be possible to set different sets of valid areas at different times.) even if the user does not report the destination and transportation plan of the management promptly, even if the transportation path selected by the logistics company is completely unknown, it is still possible to find the recyclable logistics tools that may be stolen in a prompt and accurate manner. Although the technical solution in this invention was originally designed for anti-burglary, it can also be used for alarming for other purposes.
In the case of many users, it is difficult to require each user to accurately and promptly set up all legal geographic areas. To solve this problem, the inventor has designed an automated method to identify and set valid area sets. Within the initial period of use of a new user, each recyclable logistics tool used by the new user is tracked, but does not trigger any alarm. After the data is accumulated for a period, the data is analyzed to find all geographic areas that have camped for a long time, and these geographic areas are configured as a set of legal regions automatically. Optionally, all the movement paths that a recyclable logistics tool has ever used may be find as legal geographic areas. With this technical solution, the user can enjoy the service of anti-burglary alarm without any manual operation, which making the technical solution of the present invention easier to implement.
Optionally, a blacklist area set may be set for each user. After receiving the positioning information, the current user is queried according to the tool identifier which corresponding to the positioning information, so as to obtain the blacklist area set of the user. If the positioning Information falls in any geographic area of the blacklist area set, an alarm is given in time. A global blacklist area set can also be provided separately or simultaneously, and if the received positioning information falls in any geographic area of the blacklist area set, an alarm is promptly given out.
Optionally, one of the embodiments of the specification further includes monitoring of the path. Several position points can be set in the user's valid area set. These position points are the departure point or the arrival point of the recyclable logistics tool, such as the gate of each factory or warehouse. According to these position points, several most probable paths can be planned in combination with the electronic map, and these paths are all legal paths. The historical movement trajectory of the recyclable logistics tool for the same user can also be collected, and the historical trajectory can be used as a legal path. In this way, the legal path can be automatically set. If the current positioning information of the recyclable logistics tool is not in the valid area set, and obviously deviates from these legal paths (the distance from the nearest legal path exceeds a predetermined threshold), an alarm is given out.
To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
The first embodiment of the present invention relates to a monitoring method for a shared recyclable logistics tool.
A recyclable logistics tool is shared by multiple users in a time-shared manner. The server stores valid area sets corresponding to each user (it may be the empty set if there is no use), and each valid area set contains one or more geographic areas. Optionally, the server may further store blacklist area sets respectively corresponding to one or more users. Optionally, the server may further store a globally public blacklist area set.
A wireless communication module is provided in each recyclable logistics tool for continuously transmitting wireless signals carrying the tool identifier. This wireless communication module may be a communication standard such as 4G, 5G, WIFI, or Bluetooth etc., and there is no limitation in this invention.
The monitoring method includes the following steps:
In step 101, each recyclable logistics tool continuously transmits wireless signals with its own tool identifier.
Thereafter, the process proceeds to step 102, and the server obtains continuously the tool identifier and positioning information of the recyclable logistics tools.
Thereafter, the process proceeds to step 103, and the server queries the valid area set corresponding to the current user of the recyclable logistics tool according to the tool identifier. Optionally, the blacklist area set corresponding to the current user of the recyclable logistics tool can also be queried simultaneously according to the tool identifier.
Thereafter, the process proceeds to step 104. In the server, if it is determined that the recyclable logistics tool has camped outside the geographic areas in the queried valid area set and the camp time exceeds a predetermined threshold according to the positioning information, the process proceeds to step 108 for giving out an alarm.
Thereafter, the process proceeds to step 105. In the server, if it is determined that the recyclable logistics tool is located in a certain geographic area in the blacklist area set corresponding to the user, according to the positioning information, the process proceeds to step 108 for giving out an alarm. This step is optional.
Thereafter, the process proceeds to step 106. In the server, if it is determined that the recyclable logistics tool is located in a certain geographic area of the global blacklist area set, according to the positioning information, the process proceeds to step 108 for giving out an alarm. This step is also optional.
Thereafter, the process proceeds to step 107, and the server obtains a possible travelling path corresponding to the current user of the recyclable logistics tool according to the tool identifier; if the positioning information deviates from the closest possible travelling path by more than a predetermined threshold, the process proceeds to step 108 for giving out an alarm. This step is also optional.
The execution order of the above steps 104 to 107 can be arbitrarily arranged.
With the above technical solution, even if the recyclable logistics tool is leased by a plurality of different users within a certain period of time, even if the user does not report the destination and transportation plan of the management party promptly, even if the transportation path selected by the logistics company is completely unknown, recyclable logistics tool that may be stolen can still be found in a prompt and accurate manner.
Some implementation details and variations are described in detail below.
In step 102, the server obtains positioning information in a variety of ways: Option 1. A satellite positioning module (such as a GPS module, a BOE module, a Galileo satellite navigation module, etc.) is provided in the recyclable logistics tool, and outputting the positioning information of recyclable logistics tool, and then sending to the server on the network side through the wireless communication module in the recyclable logistics tool. Option 2: There is a cellular wireless communication module in the recyclable logistics tool. When the cellular wireless communication module is registered to a base station, the position of the base station is regarded as approximate positioning information of the recyclable logistics tool. Option 3: There is a wireless receiving module in the recyclable logistics tool, such as a WIFI module. The wireless receiving module detects nearby WIFI wireless signals, reports the detected WIFI base station identifier and the corresponding WIFI wireless signal strength to the network side through the wireless communication module in the recyclable logistics tool. The network side calculates the positioning information of the recyclable logistics tool based on received information. Option 4, there is a wireless transmitting module (such as a Bluetooth module) in the recyclable logistics tool, which is configured to transmit the wireless signal carrying the tool identifier. If a mobile terminal (such as a smart phone) receives this wireless signal, the tool identifier is reported to the network side together with the location information of the mobile terminal itself as the positioning information of the recyclable logistics tool. Option 5, indirectly obtaining the position of the recyclable logistics tool according to the position of the transportation means carrying the recyclable logistics tool. Wherein, the option 2 and 4 do not carry a positioning module, and only obtain the positioning information of the recyclable logistics tool based on the wireless signals with the tool identifier continuously transmitted by the recyclable logistics tool.
In step 101 and step 102, there are a variety of ways for continuous transmission and continuous acquisition: Optionally, the wireless communication module of the recyclable logistics tool periodically transmits wireless signals. Optionally, the wireless communication module of the recyclable logistics tool transmits a wireless signal when a pre-designed trigger condition is satisfied. Optionally, the server sends an instruction for obtaining positioning information to the recyclable logistics tool when necessary, and the recyclable logistics tool carries the tool identifier and positioning information in the returned message.
There are a variety of ways to implement to give out an alarm: optionally, the alarm information is sent to the terminal device used by the current user of the recyclable logistics tool. Optionally, the alarm information is recorded in a database for future inquiry. Optionally, an alarm message is displayed on the administrator's computer. Optionally, alarm information is sent to the smart phone of the designated person. Optionally, a sound and light alarm is given out at the monitoring center. Optionally, an alarm is first given out on the terminal device of the operator, and the employees of the operator confirm the alarm information before sending the alarm information to the terminal device used by the user.
Optionally, the blacklist area set is shared by multiple users, as long as the user enters the geographic area corresponding to the blacklist area set, an alarm is given out.
Optionally, each user is provided with its own blacklist area set respectively. When the blacklist area determination is carried out, the current user of the recyclable logistics tool is first queried, then blacklist area set of the current user is acquired, and then judging whether the recyclable logistics tool is located in a geographic area in the blacklist area set according to the positioning information.
Optionally, it is possible to set a blacklist area set shared by multiple users or even all users simultaneously, and set up their own blacklist area set for some or all users at the same time, as long as recyclable logistics tools appear in the set of shared blacklist areas or in the current user's own blacklist area set, the alarm will be given out.
There are also a variety of ways to set the valid area set: Optionally, the user can set his own valid area set, such as selecting multiple geographic areas on an electronic map or selecting the names of multiple places, and saving them on the server. Optionally, the operator's administrator sets its valid area set for one or more users. Optionally, an automatic setting method is adopted, specifically: the server continuously obtains the tool identifier and positioning information of the recyclable logistics tool, wherein the positioning information includes a geographic position and a positioning time. Querying the current user corresponding to the tool identifier based on the positioning information corresponding to the tool identifier, to establish the correspondence relationship between the positioning information and the user. Counting the positioning information corresponding to the same user, and establishing a geographic area set for each user respectively. In each geographic area of the geographic area set, at least once, the user's recyclable logistics tools having camping duration which is exceeds a predetermined threshold in the geographic area.
In step 107, there are various methods for judging that the positioning information deviates from a possible travelling path that exceeding a predetermined threshold: optionally, each possible travelling path is a line, and finding the path closest to the current position of the recyclable logistics tool, and the calculation is performed as to whether the distance between the current position of the recyclable logistics tool and the closest point on the nearest path exceeds a predetermined threshold. Optionally, each possible travelling path is extended outward by a certain distance, and each travelling path is changed from a line to a belt-shaped area. If the current position of the recyclable logistics tool is not in the belt-shaped area (it is not in valid area set simultaneously), it is considered that the deviation from the possible travelling path exceeds a predetermined threshold and an alarm is given out.
In step 107, there are a variety of methods for obtaining the possible travelling path corresponding to the current user: Optionally, the user may set one or more travelling paths in advance as the possible travelling path corresponding to the user. Optionally, an administrator of the operator sets one or more travelling paths for the user in advance as possible travelling paths corresponding to the user, according to the needs of the user. Optionally, a plurality of position points are set in the valid area set of each user, and as a legal starting point or destination, a possible travelling path can be planned by through these position points in conjunction with an electronic map. If there are multiple paths for the same starting point and destination, these paths are considered as possible travelling paths, i.e., it is legal to drive on any of these paths. Optionally, the possible travelling path corresponding to the current user is a travelling path used in the history of the user. Specifically, as a production-oriented or distribution-type enterprise, a user usually uses a relatively limited number of travelling paths. As long as a certain amount of time is accumulated, almost all legal travelling paths of the user can be obtained. If driving on these paths, it belongs to a valid area, if it deviates dramatically from these paths; it belongs to an invalid area and gives out an alarm. After receiving the alarm, if the user confirms that it is a new legal path, the system can be notified to add this travelling path to the set of legal travelling paths to become a member of the valid area set after the current driving is completed.
