An embodiment of the present invention provides a data transmission method, as shown in fig. 2A, the method involves interaction among a first device, a second device, and a server, where, in the embodiment of the present invention, the first device is set as a device for providing data, such as a delivery facility or a storage device, such as a meal box, provided by the delivery device. The second device is set as a device for collecting data, such as a terminal device held by a distribution facility, a collecting device set in a roadside store, or the like. The server is also a server in the platform of the internet of things, and the method specifically comprises the following steps:
201. the first device collects device parameters.
At present, when the platform of the internet of things collects data, because the structure of a plurality of devices providing data is generally simple, that is, the first device mentioned in the present invention cannot directly establish data connection with the internet of things, such as a meal box, an express cabinet, and the like, the collected data is provided to the platform of the internet of things, for example, the data in the meal box is generally provided to a terminal device held by a rider by the meal box based on the data connection between the devices, and then the terminal device uploads the data of the meal box to the platform of the internet of things, and the terminal device also is the second device mentioned in the present invention. In order to establish data connection between the first device and the second device, the two devices are provided with the Bluetooth chips, and the data connection between the two devices is established through the Bluetooth chips, so that the first device can transmit data to the second device based on the data connection established by the Bluetooth chips after acquiring the data, and the data is uploaded to the Internet of things platform by the second device. However, the inventors have recognized that the general applicability of establishing a data connection between devices using bluetooth technology in a general sense and relying only on a second device to effect transmission of data is low, the connection is unstable and is subject to disconnection. And the second device is not always in the same position as the first device, and can be frequently disconnected and reconnected with the first device, and the situation of connection failure is likely to occur, so that the invention provides a data transmission method.
The first device needs to acquire the device parameters of the first device for transmission, and the time for acquiring the device parameters by the first device can be actually acquired in real time or acquired at regular time. If the real-time acquisition is carried out, the first equipment can carry out the acquisition of the equipment parameters at every moment, and as long as the equipment parameters are acquired, the following equipment parameter transmission process is carried out. If the acquisition is performed regularly, one way is to set an acquisition period, so that the first device determines the previous acquisition time point, superimposes the previous acquisition time point according to the acquisition period to obtain a preset acquisition time point, and starts to acquire device parameters when the current time point is monitored to be consistent with the preset acquisition time point. Or, in another mode, the historical device parameters acquired at the last acquisition time point may be acquired, the historical device parameters are monitored, and when the historical device parameters are monitored to change, the acquisition of the device parameters is started.
It should be noted that the device parameter needs to include a device usage status, for example, assuming that the first device is a meal box, the device usage status may be a meal box temperature, whether the meal box is being used, or the like. Further, in order to enable the server to process a large number of received device parameters subsequently, the acquisition time point of the device usage state and the first device identifier of the first device uploading the device usage state may also be obtained, so that the server may have a specific device parameter processing. To sum up, the device parameters acquired by the first device at least include an acquisition time point, a device usage state, and a first device identifier, where the first device identifier is the device identifier of the first device that is currently acquired.
202. The first equipment encapsulates the equipment parameters based on a preset transmission protocol, generates beacon data to be transmitted and broadcasts the beacon data to be transmitted.
In the embodiment of the present invention, after the first device acquires the device parameters, in order to broadcast the device parameters, the device parameters need to be processed to generate the device parameters in the beacon form, so as to broadcast the device parameters in the beacon form. When the device parameters in the beacon form are generated, the first device needs to acquire a preset transmission protocol, packages the device parameters based on the preset transmission protocol, generates beacon data to be transmitted, and broadcasts the beacon data to be transmitted.
In the embodiment of the present invention, the preset transmission protocol may be iBeacon (low energy consumption bluetooth). The iBeacon is a protocol of a positioning system capable of realizing low power consumption and low cost signal transmission, and can enable an intelligent terminal or other devices to execute corresponding commands within the sensing range of an iBeacon base station. With the help of an iBeacon base station, software of the intelligent terminal can approximately find the relative position of the intelligent terminal and the iBeacon base station. The iBeacon can reasonably plan the information of the beacon, and one part of the beacon is used for marking the beacon and the other part of the beacon is used for marking the data which is to be transmitted. In this way, when the first device encapsulates the device parameter based on the preset transmission protocol, first, the device parameter may be converted into a plurality of character strings according to the preset transmission protocol. For example, if the preset transmission protocol specifies that the temperature of the meal box is represented by a 3-bit character string, the 22-degree corresponding character string is 100, the 23-degree corresponding character string is 110, and the 24-degree corresponding character string is 120, when the temperature of the meal box in the equipment parameter is 23 degrees, the character string converted from the temperature of the meal box is 110. And then, arranging the character strings according to a character string arrangement mode specified by a preset transmission protocol to obtain beacon data to be transmitted. Continuing with the above description of the example of the character string 110 for converting the temperature of the meal box into, it is assumed that the first bit of the data describing the beacon in the character string arrangement specified by the predetermined transmission protocol is used to mark that the beacon is used for data transmission of the meal box, the following 2 to 6 bits describe the temperature of the meal box, and 7 and 8 bits are used to describe the ID of the meal box, so that the generated character string 110 is placed on 2 to 6 bits of the beacon data.
After the beacon data to be transmitted is generated through the process, the first device broadcasts the beacon data to be transmitted, so that the second devices passing by and within the receiving range can acquire the beacon data to be transmitted.
203. The second device scans beacon data to be transmitted broadcast within the target range.
In the embodiment of the present invention, because the broadcast of the beacon has a certain range, and the device detects that the beacon also has a certain range, for example, some intelligent terminals can only detect the beacon within a range of 3 meters centered on the intelligent terminal itself, each second device forms a target range based on the current location and the receivable distance threshold of the second device, and continuously scans the beacon data to be transmitted broadcast within the target range.
It should be noted that the first device continuously broadcasts the beacon data to be transmitted outward, and therefore, as long as the second device that passes by and is within the receiving range can acquire the beacon data to be transmitted, in the embodiment of the present invention, it is described only by taking any one of the second devices that can acquire the beacon data to be transmitted as the second device, in the process of practical application, one or more second devices may simultaneously scan the beacon data to be transmitted that is broadcast within the target range of the second device, and subsequently scan the beacon data to be transmitted of the first device at the same time, and the second devices all adopt the following method to transmit the beacon data to be transmitted.
204. And when the second equipment scans the beacon data to be transmitted, acquiring the beacon data to be transmitted, and uploading the beacon data to be transmitted to the server.
In the embodiment of the invention, when the second device scans the beacon data to be transmitted by the first device, the beacon data to be transmitted is collected and uploaded to the server.
It should be noted that, if it is very likely that the second device scans multiple different beacon data to be transmitted broadcast by multiple different first devices at the same time, the second device may upload all scanned beacon data to be transmitted to the server. The server can be a server of the internet of things platform.
205. The server receives beacon data to be transmitted.
In the embodiment of the present invention, after the second device uploads the beacon data to be transmitted, the server receives the beacon data to be transmitted, which is generated and broadcasted by the first device. Considering that sometimes some second devices of other platforms upload useless beacon data to the server by mistake, or some malicious devices upload harassing beacon data to the server, and if the server receives the uploaded beacon data in a tasteless manner, a large amount of work for filtering the beacon data is involved in the subsequent process, therefore, after receiving the beacon data to be transmitted uploaded by the second devices, the server determines the second devices uploading the beacon data to be transmitted, inquires whether the second devices have the uploading authority of uploading the beacon data, namely, performs authentication operation on the second devices, and confirms the identities of the second devices.
If the server inquires that the second device has the uploading authority, namely the second device is registered in the platform of the internet of things, the server determines that the authentication of the second device is successful, uploads successful feedback is generated, the uploading successful feedback is transmitted to the second device, the second device is informed of successfully receiving the beacon data to be transmitted through the uploading successful feedback, and then the server continues to analyze the beacon data to be transmitted based on the preset transmission protocol. On the other hand, when the second device receives the feedback that the uploading is successful, the second device determines that the server has successfully received the beacon data to be transmitted and the operation between the beacon data to be transmitted and the beacon data to be transmitted which has been uploaded successfully is finished, so that the second device finishes the current process and continues to scan other beacon data to be transmitted which are broadcast in the target range. And if the server inquires that the second device does not have the uploading authority, namely the second device is not registered in the platform of the internet of things, determining that the authentication of the second device fails, removing the beacon data to be transmitted uploaded by the second device, ending the current process, and continuously receiving other beacon data to be transmitted.
206. The server analyzes the beacon data to be transmitted based on a preset transmission protocol to obtain equipment parameters, and pushes the equipment parameters to a receiver.
In the embodiment of the invention, after the server receives the beacon data to be transmitted, the beacon data to be transmitted is in a beacon form and is not the directly transmitted equipment parameter, so that the specific equipment parameter content can be known only by analyzing the beacon data to be transmitted, and the acquisition time point, the equipment use state and the first equipment identifier included in the equipment parameter are obtained.
The server analyzes the beacon data to be transmitted, which is a reverse analysis, that is, the server also analyzes the beacon data to be transmitted based on the preset transmission protocol. Specifically, the server divides beacon data to be transmitted according to a string arrangement mode specified by a preset transmission protocol to obtain a plurality of strings. And then, according to a preset transmission protocol, performing data conversion on the plurality of character strings to obtain equipment parameters. For example, assuming that the preset transmission protocol specifies that the temperature of the meal box is represented by a character string of 3-bit characters, and the temperature of the meal box is 2 to 6 bits of the beacon data to be transmitted, the character string corresponding to 22 degrees is 100, the character string corresponding to 23 degrees is 110, and the character string corresponding to 24 degrees is 120, when the 2 to 6 bits of the beacon data to be transmitted are 110, it may be determined that the temperature of the meal box in the device parameter marked by the beacon data to be transmitted is 23 degrees. It should be noted that, in practical applications, the preset transmission protocols used by the server and the first device are corresponding, so that the reverse parsing of the beacon data can be realized. In addition, an iBeacon service can be set in the Internet of things platform where the server is located, and the received beacon data to be transmitted is analyzed based on the iBeacon service. In addition, in order to facilitate subsequent query of a large amount of beacon data to be transmitted uploaded by the second devices, the server may further include a database, and the received beacon data to be transmitted is stored in the database.
After the device parameters are obtained through analysis, in practical applications, operations of some stores need to use the device parameters, for example, a restaurant wants to know the actual temperature of food in a food box in real time, and therefore, the server will push the device parameters to a receiving party. The receiving party may be a store to which the first device is bound, for example, the first device is a meal box, the first device only serves store a, the receiving party is store a, and the device parameters are pushed to store a.
In the practical application process, the platform of the internet of things provides a data analysis function, and can synthesize and analyze a large number of device parameters to generate a data report, so that the requirement of data analysis on the receiving party is shown in fig. 2B, and the data analysis can be realized based on the following method:
207. when the server receives a report generation request sent by a receiving party, a plurality of target equipment parameters including a first equipment identifier are extracted from all the currently analyzed equipment parameters.
In the embodiment of the present invention, when the server receives the report generation request sent by the receiving party, since only the first device related to the receiving party is the object of the research by the receiving party, which has a research significance, the server may extract a plurality of target device parameters including the first device identifier from all the device parameters obtained by the current analysis, and subsequently analyze the plurality of target device parameters.
208. The server divides the plurality of target device parameters into at least one target data group.
In the embodiment of the present invention, it is considered that each second device passing through the first device acquires beacon data broadcast by the second device and uploads the beacon data to the server, and the server receives a large amount of the same beacon data to obtain a large amount of the same device parameters, and the acquisition time points of the device parameters are necessarily the same, so that when the server analyzes a plurality of target device parameters, the server needs to divide the plurality of target device parameters into at least one target data group, so that the acquisition time points of the target device parameters included in each target data group are the same, so as to normalize the large amount of the same target device parameters.
When the target data groups are divided, the server firstly reads the acquisition time points included by each target device parameter in the target device parameters, and divides the target device parameters according to the acquisition time points to obtain at least one initial data group, wherein the acquisition time points of the target device parameters included by each initial data group in the at least one initial data group are the same. Then, considering that sometimes errors may occur in the acquisition of device parameters or in the transmission of beacon data, for example, a large amount of target device data in a certain initial data group indicates that the a-meal box is in 15: and when the temperature of the food box at 06 hours is 30 ℃, only one piece of target equipment data indicates that the temperature of the food box A is 5 ℃, and then the temperature of the food box A is 5 ℃, so that the temperature of the food box A is 5 ℃ of wrong target equipment data, and the wrong target equipment data needs to be filtered. Or there may be some misjudged beacon data in the authentication process, for example, the beacon data is not actually uploaded by the second device registered in the platform of the internet of things but is missed by the authentication, and such target device data also needs to be filtered out. Therefore, for each initial data group in at least one initial data group, the server determines the device usage status included in the target device parameters in the initial data group, and removes the abnormal device parameters in the initial data group to obtain the target data group. The device use states included by the abnormal device parameters are inconsistent with the device use states included by other target device parameters except the abnormal device parameters in the initial data set, so that the target device data in the initial data set are cleaned. And finally, respectively removing the abnormal equipment parameters from at least one initial data group to obtain at least one target data group.
209. And the server acquires a preset report template, fills at least one target data group into the preset report template, generates a data report and returns the data report to a receiver.
In the embodiment of the invention, after the at least one target data group is obtained, the server can generate the data report according to the at least one target data group. The server may be provided with a preset report template, the preset report template specifies a filling position or a representation mode of each data, and the number of the preset report templates may be one or more. For example, assuming that the target device parameters in the target data group include the meal box temperature and the collection time point, the preset report template may be in a form including a meal box temperature item and a collection time item, and then the preset report template is filled with at least one target data group according to the filling position indicated by the preset report template to generate the data report. Or, the preset report template may specify that the target data sets are represented by using a representation manner such as a column diagram or a line diagram, and the server may generate a time-temperature rectangular coordinate system, and display at least one target data set in the rectangular coordinate system to form a column diagram or a line diagram. After the data report is generated, the server returns the data report to the receiver for reference.
It should be noted that, because the target device parameters included in each target data group are all consistent, when at least one target data group is filled in the preset report template, for each target data group, any target device parameter therein may be selected to represent the target data group, so that a plurality of target device parameters included in the target data group are integrated into one target device parameter, and the workload of calculating data is reduced.
