Example 1
Referring to fig. 1, the present embodiment provides a global internet of things device access method, which can be applied to access management of global internet of things devices 10 in an internet of things system as shown in fig. 2. By the method, the global Internet of things equipment 10 can be automatically accessed to the corresponding gateway, and further, the transmission of the working condition data of the equipment and the like can be realized. Even if the position of the global internet of things device 10 changes, manual access switching processing or the like is not required.
In this embodiment, the global internet of things device 10 refers to an internet of things terminal product capable of working in different country regions, can be accessed to various device controllers, supports device operating condition data acquisition, and can upload the acquired data to the cloud end through the global internet of things. The main server 20 is generally a computer with high-speed CPU computing capability, and is generally assigned with a fixed access domain name, and based on the internet of things device access platform, it may store and analyze device data of the accessed global internet of things device 10, so as to implement intelligent control and the like. In this embodiment, no matter which country the global internet of things device 10 moves to, it can access the main server 20 through the fixed domain name. The service server 30 is usually deployed in the country region involved in the service, for example, it may be deployed in different country regions of china, germany, usa, etc. Of course, in the same country, only one service server may be deployed, or multiple service servers may be deployed, which may depend on service requirements and the like. Notably, each service server 30 can interface to the internet of things device access platform through a global communication network. In this embodiment, the service server 30 is connected to the global internet of things device 10 corresponding to the service area, so that the data transmission speed of the global internet of things device 10 can be increased, and the problem of the communication speed between the global internet of things device 10 and the access platform due to different country areas can be solved.
The following describes the access method of the global internet of things device in detail.
Step S110, receiving related location information sent by the global internet of things device 10, where the related location information includes GPS positioning data of the global internet of things device 10 and location data of a base station to which the global internet of things device is connected.
Illustratively, when a global internet of things device 10 needs gateway access, information related to its own location is sent to the host server 20, so that the host server 20 can determine the location of the global internet of things device 10, and then select an appropriate gateway to be accessed from the known plurality of service servers 30.
In one embodiment, for example, the relevant location information may be the location data obtained by a global GPS positioning module in the global internet of things device 10, and the location data of the base station to which the global internet of things device 10 is connected, and generally, the location of the global internet of things device 10 may be determined by obtaining the location data of three connected base stations. The base station may include a base station of a current country region, or may include base stations connected across country regions.
It should be noted that before the global internet of things device 10 sends the relevant location information, the global internet of things device 10 should have established a connection relationship with the main server 20 and perform a device authentication operation, that is, the main server 20 performs step S110 after performing an authentication operation on the global internet of things device 10. The current Internet of things equipment is ensured to be legal registered equipment under the Internet of things equipment access platform through equipment authentication operation, and the access or attack of fake equipment and the like can be effectively prevented, so that the safety of an Internet of things system is ensured and the like.
Step S120, performing device positioning calculation according to the base station location data to obtain base station positioning data, and calculating an actual location of the global internet of things device 10 according to a formula.
Considering that the global GPS positioning mode has high positioning speed and high accuracy, but is greatly influenced by natural environmental factors such as weather, and the base station positioning mode is not influenced by environmental factors such as weather and high buildings, but in the position without the base station, because of global positioning, the error range is larger. For this reason, in this embodiment, the accurate location information of the global internet of things device 10 is jointly acquired through two different positioning data. For the convenience of distinguishing from the GPS positioning data, the actual position data of the global internet of things device 10 calculated based on the position data of the base station is recorded as the base station positioning data so as to be unified with the measurement standard of the GPS positioning data.
Exemplarily, the actual position of the global internet of things device 10 will be calculated according to the following formula:
the first preset positioning weight and the second preset positioning weight may be preset, and may be specifically set according to an actual service instance, for example, the number of base stations in the service area, the area weather, and the like may be considered. It is understood that by combining two positioning data to determine the actual position of the global internet of things device 10, the positioning accuracy can be improved.
Considering that the natural environment such as weather in some countries may be very bad, or the fundamental wave positioning cannot be performed in some remote places without base stations, the GPS positioning data or the base station position data may be received abnormally. Optionally, if the related information only includes the received GPS positioning data, the GPS positioning data may be used as the actual position of the global internet of things device 10; alternatively, if the relevant location information only includes the location data of the plurality of connected base stations, the actual location of the global internet of things device 10 may be calculated by a three-point positioning algorithm according to the location data of the base stations. Of course, if the two kinds of data are received abnormally, the main server 20 will be used as its gateway to be accessed or the global internet of things device 10 will be accessed to a service server set by default in the system.
Step S130, selecting a target service server 302 from the actual positions of the global internet of things devices 10 and the actual positions and load states of the candidate service servers 301. Wherein, the target service server 302 is used as a gateway to be accessed of the global internet of things device 10.
In this embodiment, the main server 20 stores relevant information of each service server in advance, such as a site address, an actual geographic location, availability, a load status, and the like of the service server. The candidate service server 301 mainly refers to a currently available service server.
Exemplarily, when the target service server 302 is selected, the location and the load state of each candidate service server 301 are comprehensively considered, so that a situation that the response is slow due to a large load of the accessed service server can be prevented, and the data transmission rate of the global internet of things device 10 is ensured.
In one embodiment, as shown in fig. 3, the selecting of the target service server 302 includes:
step S210, calculating a physical distance between each candidate service server 301 and the global internet of things device 10 according to the actual positions of the global internet of things device 10 and each candidate service server 301, where the physical distance is used to calculate a physical distance score.
In this embodiment, the physical distance mainly refers to a straight-line distance from the global internet of things device 10 to each candidate server. Illustratively, the physical distance between the global internet of things device 10 and each candidate service server 301 can be calculated through the corresponding actual position, and then a physical distance score of each physical distance is calculated. Generally, the closer the physical distance, the smaller the physical distance score; conversely, the greater the physical distance score. In one embodiment, the physical distance corresponding to each candidate service server 301 may be normalized by presetting a maximum physical distance, so as to obtain a physical distance score corresponding to each candidate service server 301 with the maximum physical distance as a reference. It will be appreciated that by performing the normalization process on the same basis, the problem of inconsistent scores between physical distances for different levels can be avoided.
For example, if there are candidate service servers A, B and C and the corresponding physical distances are 5km, 80km, and 150km, respectively, and the maximum physical distance is 500km, then the physical distance scores corresponding to candidate service servers A, B and C, respectively, are obtained by the normalization process, which is 1, 16, and 30, respectively, and the normalized data is converted to a percentage numerical representation.
In step S220, the current load status score of each candidate service server 301 is obtained.
The load status score may be obtained, for example, by the load level or load rate of each candidate traffic server 301. For example, the load rate of a candidate service server is 40%, i.e., the load status score is 40. It can be understood that the less the load, the better the state, and the smaller the corresponding load rate, i.e. the smaller the score of the loaded state; conversely, if the load is more, the load status score is also greater. Generally, if the load mounted by the service server is more, the required processing resources are often needed more, and for the equipment in the internet of things, this easily causes that the service server may not be able to process the message of the equipment in the internet of things in time, and further, response delay occurs.
Step S230, calculating an access index of each candidate service server 301 according to a preset formula.
Exemplarily, after obtaining the physical distance score and the load status score of each candidate service server 301, the access index of each candidate service server 301 may be obtained by calculating according to the following preset formula. The preset distance weight and the preset load weight can be determined according to actual service conditions, empirical values obtained through multiple tests and the like, and the preset formula is as follows:
access index =1- (preset distance weight physical distance score + preset load weight load status score).
Step S240, selecting the candidate service server with the largest access index as the target service server 302.
Then, after calculating the access index to each candidate service server 301 separately, the target service server 302 with the largest access index may be the one that is needed. It can be understood that, for a service server with a closer physical distance and a lower load degree, the corresponding access index will be higher, which means that the service server is more suitable to be an access gateway of the global internet of things device 10. Generally, the closer the physical distance between the internet of things device and the service server is, the shorter the data transmission time is, i.e. the faster the data transmission efficiency is. When the load rate of the service server is lower, the speed of the service server responding to the global internet of things equipment is higher. In the embodiment, when the service server to be accessed is selected, the selection result is not appropriate due to only considering the nearest distance or the load condition by comprehensively considering the global geographic position and the load degree.
Step S140, sending the site address of the target service server 302 to the global internet of things device 10.
Exemplarily, after the target service server 302 is determined, the site address thereof is sent to the global internet of things device 10, so that the global internet of things device 10 sends an access request and performs device access.
Considering that the position of the global internet of things device 10 may move, in order to ensure that the global internet of things device 10 can always be in a better access state, the global internet of things device 10 will send an updated relevant position to the main server 20, so that the main server 20 determines whether to select a new target service server 302. Further optionally, the global internet of things device access method further includes:
if the updated relevant position information sent by the global internet of things device 10 is received, a target service server 302 is reselected from the candidate service servers 301 according to the step of selecting the target service server 302.
It can be understood that, by using the updated location information to relocate the global internet of things device 10 and then selecting a most suitable target service server 302 according to the updated actual location, the data transmission rate of the global internet of things device 10 can be in a higher state, and the like.
According to the global Internet of things equipment access method, the global Internet of things equipment sends the position information of the global Internet of things equipment to the main server, and the main server selects the most appropriate service server for access by comprehensively considering the position factors and the load states of the service servers, so that the automatic access management of the global Internet of things equipment can be realized, and the access is not adjusted manually even if the position changes; because the actual position and the load condition are taken as the priority conditions, a most suitable service server is selected as an access gateway, and the better data transmission speed and the like can be ensured.
Example 2
Referring to fig. 4, the present embodiment provides a global internet of things device access method, which is applied to a global internet of things device 10, and the global internet of things device access method includes:
step S310, sending relevant location information to the main server 20, where the relevant location information includes GPS positioning data of the global internet of things device 10 and base station location data connected to the global internet of things device 10, so that the main server 20 performs device positioning calculation according to the base station location data to obtain base station positioning data, and calculates an actual location of the global internet of things device 10 according to the formula in embodiment 1.
It is understood that the relevant location information is the same as the relevant location information received by the main server 20 in the above embodiment 1, and the obtaining and the content of the relevant location information can be referred to the above embodiment 1, so that the description is not repeated here.
Step S320, receiving response information including the site address of the target service server 302 sent by the main server 20, where the target service server 302 is selected and determined according to the actual location of the global internet of things device 10, the actual locations of the plurality of candidate service servers 301, and the load status.
Exemplarily, when the host server 20 integrates the location information and the load status of each service server to select a target service server 302, the host server 20 will send the site address of the target service server 302 to the global internet of things device 10. For a specific selection process of the target service server 302, reference may be made to the above embodiment 1, and therefore, a description thereof is not repeated here.
Step S330, sending an access request to the site address for accessing the target service server 302.
Illustratively, after acquiring the site address, the global internet of things device 10 sends an access request message to the target service server 302. It should be understood that after establishing a connection with the target service server 302, the global internet of things device 10 generally needs to perform device authentication, that is, the service server will verify device information of the global internet of things device, so as to ensure that the global internet of things device is a legal registered device under the internet of things device access platform. And after the authentication is successful, the equipment working condition data transmission and the like can be normally sent. The operating condition data herein mainly refers to data related to business acquired by the global internet of things device 10 through sensors or the like or acquired by other means.
In addition, when the global internet of things device 10 is successfully accessed to the target service server 302 and the authentication is successful, the global internet of things device 10 will start timing after sending the device working condition data each time, and determine whether the time length from the last sending of the device working condition data exceeds the preset time length before sending the device working condition data the next time; and if so, re-sending the equipment authentication request, and sending corresponding equipment working condition data after receiving the message of successful authentication.
It can be understood that, in view of security, when the global internet of things device 10 does not send data for a long time, the access platform of the internet of things device may delete the access information of the device in time, and therefore, an authentication operation is required each time after data is not transmitted for a long time, which may prevent the service server from being exposed, and may also prevent hackers and the like from attacking the service server and even the entire access platform of the internet of things device through the global internet of things device 10, thereby improving system security.
Optionally, as shown in fig. 5, after accessing the target service server 302, the global internet of things device access method further includes:
step S340, access the target service server 302.
Step S350, detecting whether the response time of the currently accessed target service server 302 exceeds a preset delay time threshold. If yes, step S360 is executed, otherwise, the current access state is maintained.
Step S360, sending test messages to a plurality of service servers of the pre-stored corresponding site addresses.
Exemplarily, the global internet of things device 10 may store a manually inputted or accessed service server in advance, and if the currently accessed service server fails to respond in time (i.e., response time is out), an attempt may be made to access a new service server.
