Description
Technical Field
The invention relates to the technical field of communication, in particular to a communication method for an advertising machine and the advertising machine.
Background
In recent years, with the development of society, advertisement machines have begun to appear in a large number of public places such as outdoors or communities to replace conventional electronic and/or non-electronic advertisement boards. Smart advertisers have become increasingly accepted by the marketplace and clients due to their good advertising image quality and interactivity, and the extremely high targeting and customization capabilities.
The existing intelligent advertising machine adopts an Android operating system which is the same as that of a smart phone or a smart television, but the intelligent advertising machine is different from private equipment of the mobile phone and the television, and the intelligent advertising machine is generally more widely installed in places such as intersections, parks, basements, elevators and the like, and the use environment is more complex. In recent years, the rapid development of internet technology has been benefited. The latest intelligent advertising machine is based on cloud remote control and program remote release and downloading modes. The complex and repeated operation that maintenance personnel get close to the gate to periodical programs on the advertising machine is avoided, and management personnel can control and release the advertising programs to the advertising machine terminals of a plurality of access systems through the management system.
Because the use environment of the advertising machine is complex, the difference of the used network access modes is relatively large. The advertisement machine can access the server through various modes such as 4G, 5G, a wired network, a WIFI hotspot and the like. Reliability, stability, and performance of communication between the advertiser and the server are issues that one skilled in the art would need to address.
There are two methods for communication between the advertiser and the server in the current field, one is that the server and the advertiser establish a long connection message channel through the TCP protocol. The method has the advantages that the real-time performance of message transmission before the server and the advertising machine is ensured, and the message can be sent to the successful receiving time within one second as long as the message channel is established successfully. However, this method has high requirements on network environment, and in actual use, a large number of advertisement machines and servers are unstable in communication due to the complex network environment, so that the problem is very fatal. Another method is that the advertisement machine polls the request server through the HTTP protocol, the method has the advantages of high reliability and stability, but the server can not actively send messages to the advertisement machine, and the advertisement machine can only actively request by a single side of the advertisement machine. The advertiser cannot know when the server-side data will change, and therefore can only periodically and circularly send a large number of requests to the server, which are very stressed, wherein the large number of requests are invalid. The performance problem is particularly evident, and for this reason, a stable, reliable and high-performance method is needed.

As a further optimization, the advertisement machine obtains the latest advertisement data from the server based on the instruction received by the message system, and specifically comprises:
after the server has the latest advertisement data, a delivery instruction is sent to the advertisement machine through the message system, and after the advertisement machine receives the delivery instruction, the HTTP function interface is called to acquire the latest advertisement data from the server.
As further optimization, the advertisement machine obtains the latest advertisement data from the server based on the query result of the HTTP polling interface, and specifically comprises the following steps:
the advertisement machine calls the HTTP polling interface to request server data unidirectionally, compares the local data version with the server data version, and judges that the server has the latest advertisement data if the local data version is inconsistent with the server data version, and calls the HTTP functional interface to acquire the latest advertisement data from the server.
As further optimization, the advertisement machine is an advertisement machine based on an Android system, and the message system is a Netty message system.
As a further optimization, the first time is 30 seconds, the second time is 1 minute, and the preset times are 3 times.
In a second aspect, an advertisement machine is provided, wherein the advertisement machine is configured to actively initiate a request to establish a long connection message system with a server after the advertisement machine is started and connected to a network; if the message system is successfully established, data communication is carried out between the message system and the server, if the message system is established, the establishment is continuously attempted, and after the number of attempts exceeds the preset number, the message system is still established, the HTTP polling interface is called to request data from the server; when the data communication is carried out between the message system and the server, checking whether the message system is normal or not every first time, if the message system is disconnected, attempting to reestablish, and after the number of attempts exceeds the preset number and the message system is still established, calling an HTTP polling interface to acquire data communication with the server; and when the HTTP polling interface is called to request data from the server, attempting to reestablish the message system every second time, and if the message system is reestablished successfully, carrying out data communication with the server through the message system.

Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
The invention provides a communication method for an advertising machine and the advertising machine, and the main technical scheme comprises the following steps: when the advertisement machine is started and is connected to a network, actively initiating a request to establish a long connection message system with a server; if the message system is successfully established, the advertisement machine performs data communication with the server through the message system, if the message system is failed to be established, the advertisement machine continues to attempt to establish, and after the number of attempts exceeds the preset number and the message system is still failed to be established, the advertisement machine calls an HTTP polling interface to request data from the server; when the advertisement machine performs data communication with the server through the message system, checking whether the message system is normal or not every first time, if the message system is disconnected, the advertisement machine tries to reestablish, and when the number of attempts exceeds the preset number and the message system is still established, the advertisement machine calls an HTTP polling interface to request data from the server; when the advertisement machine calls the HTTP polling interface to request data from the server, the advertisement machine tries to reestablish the message system every second time, and if the message system is reestablished successfully, the advertisement machine communicates data with the server through the message system.
In particular, the present invention classifies HTTP requests into two categories, master poll requests and other function requests. Other function requests can be triggered only under specific conditions, and the advertiser can communicate with the server by using the message system preferentially. When the server performs data change such as advertising, the server actively sends a program change message to the advertising machine through the message system, and the advertising machine calls corresponding other function requests such as acquiring the latest program interface to acquire the latest program and updating the local program. The device periodically monitors the availability of the messaging system. When the message system is abnormal, the data version stored in the terminal is compared with the data version of the server at the timing when the message system is switched to the main polling request, if the program version is inconsistent, the advertisement machine also acquires new advertisement release, the advertisement machine initiatively calls a corresponding functional interface, such as acquiring the latest program interface to update the locally played program, only data comparison judgment is carried out in the main polling, complex logic operation and time-consuming database operation are not involved, the consumption of the polling function on the server resource is reduced to the minimum, the concurrency of the polling mode and the server performance are greatly improved, and meanwhile, the follow-up functional operation is completed by using the HTTP request. The stability is effectively ensured.
Examples
The communication method for the advertising machine of the embodiment is applied to a system comprising an advertising machine, a server, a message system, an HTTP polling interface and an HTTP function interface.
Wherein, the advertisement machine: the method comprises the steps that message connection initiating equipment is used for carrying out message communication on an advertisement machine through a message system and a server under normal conditions, the availability of the message system is detected regularly, when the message system is abnormally disconnected, the advertisement machine is connected with the message system again regularly, when the number of reconnection times is exceeded, the message system is not connected successfully, the system is switched to use an HTTP polling interface to carry out data communication with the server, meanwhile, the advertisement machine is continuously connected with the message system again regularly, and when the system reconnection is successful, the message system is switched to use the server to carry out data communication. In this embodiment, the advertisement player may be an advertisement player based on an Android system, which supports the playing of common video, audio and pictures, and embeds an sqllite database.
And (3) a server: the server side of the message system comprises an HTTP polling interface and an HTTP function interface provider, and the server is divided into a message system server and an HTTP interface server. The server may actively issue advertisements and other various control instructions to the advertising devices via the messaging system. In this embodiment, the server supports the Java Web interface and installs and uses the Netty message system.
Message system: the advertisement machine and the Server establish a message channel through a TCP protocol, the Server is used as a Server side of the message system, and the advertisement machine is used as a Client side of the message system. After the advertisement machine is started, the advertisement machine actively establishes a message system connection with the server and keeps data exchange. Both the client and the server can send data to each other through the message system, and the message system is reconnected at regular time when the advertiser detects that the message system is disconnected. The message system is not successfully connected beyond the reconnection times, the system is switched to use the HTTP polling request to carry out data communication with the server, and meanwhile, the advertisement machine continues to reconnect the message system at regular time. And when the system reconnection is successful, switching to use the message system and the server for data communication.
HTTP polling interface: the server provides an HTTP polling interface for the advertisement machine to call, and the server can only call the server interface to acquire related data in a circulating way because the interface call can only be initiated by the advertisement machine and the server can not actively send data to the advertisement machine. The performance is poor but the reliability is high. Therefore, only the data version comparison judgment is carried out in the main polling interface, and complex logic operation and time-consuming database operation are not involved. The consumption of server resources by the polling function is minimized. The concurrency and the server performance of the polling mode are greatly improved. And meanwhile, the subsequent function operation is completed by using the HTTP function request. The stability is effectively ensured.
HTTP function interface: the HTTP function interface needs to be triggered by using an HTTP polling interface or a message system, and the advertisement machine initiatively initiates the request, so that the stability is very high. In the system, the latest advertisement data interface, the startup and shutdown plan, the volume plan and other interfaces are all classified as HTTP function interfaces. For example, when the user issues an advertisement, the server preferably uses the message system to notify the advertiser that a new advertisement is available, and the advertiser invokes the latest advertisement acquisition interface to acquire advertisement data. When the message system is abnormal, the advertiser enables the main polling interface to circulate and request the service to compare the local version with the server version, and when the versions are inconsistent, the advertiser invokes the latest advertisement interface to acquire advertisement data.
The communication method for the advertising machine according to the embodiment, as shown in fig. 1 and 2, includes the following steps:
and step 1, after the advertisement machine is started and is accessed to a network, actively initiating a long connection message system with a server.
And step 2, if the message system is failed to be established, the advertiser continues to try to establish, and if the number of attempts exceeds 3 and is unsuccessful, the server data is requested unidirectionally by using an HTTP master polling mode, and whether the local data version and the server data version are consistent is compared.
And step 3, if the step 1 is successfully established or the step 2 is successfully attempted to establish the message system connection, the advertising machine and the server can realize bidirectional data communication through the message system.
And 4, when the message system is used for communication, the advertisement machine needs to check whether the message system is normal every 30 seconds, if the message system is found to be disconnected, the advertisement machine continues to try to establish the message system, and if the number of attempts exceeds 3 and is unsuccessful, the server data is requested unidirectionally by using an HTTP master polling mode.
And 5, when the server data is requested unidirectionally by using an HTTP polling mode, starting a timing task, attempting to reestablish the message system by the advertisement machine every 1 minute, stopping HTTP main polling request if the message system is reestablished successfully, and switching back to using the message system for server communication.
And 6, when the server data change, if a new advertisement is put, the server preferentially uses the message system to send an advertisement putting instruction to the advertisement machine if the message system is normal, and the advertisement machine uses an HTTP function interface (obtaining the latest advertisement interface) to obtain the latest advertisement data after receiving the message instruction.
And 7, when the server data change, if a new advertisement is put in, if the message system is abnormal, the advertiser starts a main polling interface circulation request service to compare the local version with the server version, and after the version is inconsistent, the advertiser acquires the latest advertisement data by using an HTTP functional interface (acquiring the latest advertisement interface).
Based on the above technical scheme, the embodiment also provides an advertisement machine, which is used for actively initiating a request to establish a long connection message system with a server after the advertisement machine is started and is connected to a network; if the message system is successfully established, data communication is carried out between the message system and the server, if the message system is established, the establishment is continuously attempted, and after the number of attempts exceeds the preset number, the message system is still established, the HTTP polling interface is called to request data from the server; when the data communication is carried out between the message system and the server, checking whether the message system is normal or not every first time, if the message system is disconnected, attempting to reestablish, and after the number of attempts exceeds the preset number and the message system is still established, calling an HTTP polling interface to acquire data communication with the server; and when the HTTP polling interface is called to request data from the server, attempting to reestablish the message system every second time, and if the message system is reestablished successfully, carrying out data communication with the server through the message system.
It can be understood that, since the advertisement machine according to the embodiment of the present invention is an advertisement machine for implementing the communication method according to the embodiment, for the advertisement machine disclosed in the embodiment, since the advertisement machine corresponds to the method disclosed in the embodiment, the description is simpler, and the relevant points refer to the part of the description of the method.
