The system comprises a user monitoring module, a car communication module, a car bus module and an internet, and also comprises a WEB communication module supporting a TCP protocol connection function, wherein the user monitoring module and the car communication module establish connections comprising a TCP protocol with the WEB communication module through the internet respectively; and the car bus module is connected with the car communication module. By embedding the TCP protocol into the WEB communication module supporting an HTTP protocol, the WEB communication module is enabled to support the TCP protocol and then can establish TCP connections with the user monitoring module and the car communication module respectively so as to realize SOCKET interception, so the WEB communication module can timely know that data transmission is to be performed and transmit data, and the real-time property is improved. Due to no need of regularly transmitting data transmission requests, the load of a network and a server is lightened.
Description
Technical field
The present invention relates to the automobile remote monitoring technology, particularly the remotely monitoring car in real time method and system.
Background technology
Current automobile has mostly adopted the automobile bus technology.Automobile bus is the unified exchanges data channels of utility service such as the electronic equipment, control, measuring instrument of the various complexity of automotive interior.Think that with automotive expert the introducing of data bus technology also will be a milestone of automotive electronic technology development over nearly 10 years.
The introducing of bussing technique makes remote monitoring become reality.Along with the fast development of mobile communications network and fhe global the Internet and fusion day by day, a lot of wireless internet network technology have been produced.Make the user connect the internet out of doors and become possibility.So just can and send data on the automobile bus by the internet transmission and just can realize remote monitoring.
Existing automobile remote monitoring system is to transmit a request to the WEB server by user side, and the WEB server just extracts the result and sends it to user side from database then.This automobile remote monitoring system will embody real-time and just can only send request, the continuous response request of WEB server then regularly for the WEB server at user side.At this moment such a case will occur: motoring condition changes suddenly, accelerates suddenly as automobile, drives over the speed limit.User side is just seen the state of change after a while, takes control measure-transmission automobile brake order this time, may be late.That is to say that we can not know that vehicle condition changes and then delayed the best opportunity of preventing contingent accident in the very first time; User side sends request regularly for the WEB server also can cause such a case, and vehicle condition does not have the time of variation, and user side sends request also for surely the WEB server end; This has just caused network resources waste, increases load of server.So existing automobile remote monitoring system real-time is relatively poor, can not satisfy the demand of present monitoring.And existing system has also increased network and load of server.
Summary of the invention
In view of this, main purpose of the present invention is to provide a kind of method and system of remotely monitoring car in real time, with the problem that real-time is not enough and offered load is heavy that solves existing automobile remote monitoring system.
For achieving the above object, technical scheme of the present invention specifically is achieved in that
A kind of remotely monitoring car in real time system comprises:
User monitoring module, WEB communication module, auto communication module, automobile bus module, internet, it is characterized in that described WEB communication module comprises the WEB server that embeds Transmission Control Protocol, user monitoring module, auto communication module are set up with described WEB server by the internet respectively and are included being connected of Transmission Control Protocol, and described automobile bus module is connected with the auto communication module.
A kind of remotely monitoring car in real time method comprises
A1, automobile communication module receive on the automobile bus module the vehicle condition parameter then with WEB communication module database in the previous state data compare, judge whether the vehicle condition parameter changes, as change, then execution in step A2; Otherwise, execution in step A3 then;
A2, connect to WEB communication module transmission data by the Transmission Control Protocol set up;
A3, to WEB communication module transmission data;
A4, when setting up Transmission Control Protocol and be connected the WEB communication module and receive the data of auto communication module transmission, the user monitoring module gives the user monitoring module with this transfer of data;
The data from the WEB communication module that A5, user monitoring module will receive show, and need to judge whether the transmission control information; Do not need, then execution in step A6; Otherwise, execution in step A7 then;
The following secondary data of A6, wait WEB communication module;
A7, user monitoring module are transferred to the WEB communication module with control information, and wait for secondary data under the WEB communication module;
A8, WEB communication module connect to automobile communication module transmission control command by the Transmission Control Protocol of having set up after the control information parsing that receives is become control command simultaneously;
A9, auto communication module are transferred to the control command that receives on the automobile bus, finish corresponding control.
A kind of remotely monitoring car in real time method and system provided by the invention, by in the WEB communication module of supporting http protocol, embedding Transmission Control Protocol, make it support Transmission Control Protocol, can set up TCP between WEB communication module and user monitoring module and the auto communication module like this is connected, realize that SOCKET intercepts, as long as user monitoring module and auto communication module will be carried out transfer of data, data can be known and transmit to the WEB communication module very first time like this.Just do not transmit data after not needing to send as before again the transmission request, improved real-time; Owing to also without the timed sending data transfer request, alleviated the load of network and server.
