Embodiment
Be described principle of the present invention and feature below in conjunction with accompanying drawing, example, only for explaining the present invention, is not intended to limit scope of the present invention.
A kind of auto-update application scenarios schematic diagram based on electric motor car central control system that Fig. 1 provides for the embodiment of the present invention.
With reference to Fig. 1, message is sent to cloud server by User Datagram Protoco (UDP) (UserDatagramProtocol, UDP) by the central control system of electric motor car, and message comprises version number.After cloud server receives message, the corresponding firmware version information of version number is searched from MongDB (database), and according to the timestamp in firmware version information by firmware version information temporally inverted order order arrange, by the time more late be placed on before, by time putting behind comparatively early, finally using the firmware version information of sequence in first place as the first firmware version information, the first firmware version information is herein up-to-date firmware version information.
Judge that whether the timestamp in the first firmware version information is identical with the timestamp in the second firmware version information; If the timestamp in the first firmware version information is greater than the timestamp in the second firmware version information, then check information-setting by user; If information-setting by user is auto-update information, then the first firmware version information and download address are encapsulated as upgrading command information.After user is set to permission on APP server, database changes the is_update in this table into true by false.
Upgrading command information is put into transmit queue, and thread transfers upgrading command information from transmit queue, and sends to described central control system, and central control system is downloaded from content distributing network (ContentDeliveryNetwork, CDN).
A kind of automatically updating method flow chart based on electric motor car central control system that Fig. 2 provides for the embodiment of the present invention.
With reference to Fig. 2, in step S201, receive the message that central control system is sent by User Datagram Protoco (UDP) UDP, described message comprises version number.
In step S202, from database, from database, obtain the first firmware version information according to described version number.
Here, the first firmware version information specifically can refer to table 1, as shown in table 1:
Table 1
| Field | Data type | Exemplary contents |
| _id | ObjectId | ObjectId |
| name | String | Firmware name |
| version | String | Firmware version |
| bytesize | int | Byte number |
| path | String | Download path |
| date | Date | Timestamp |
In step S203, judge that whether the timestamp in the first firmware version information is identical with the timestamp in the second firmware version information, if the timestamp in the first firmware version information is greater than the timestamp in the second firmware version information, then perform step S204; If the timestamp in the first firmware version information equals the timestamp in the second firmware version information, then terminate, namely do not need to upgrade.
Here, the timestamp in the second firmware version information is the timestamp of the firmware version information that electric motor car uses.
In step S204, check whether information-setting by user is auto-update information, if information-setting by user is auto-update information, then perform step S205; If information-setting by user is not auto-update information, then terminate.
Here, after user is set to allow auto-update on APP server, database changes the is_update in table 2 into true by false.Specifically as shown in table 2:
Table 2
| Field | Data type | Exemplary contents |
| _id | ObjectId | ObjectId |
| sn_id | String | Vehicle SN |
| prot_type | String | Protocol type |
| state | int | State |
| sim_id | String | SIM card is encoded |
| imei | String | imei |
| phone | String | SIM card cell-phone number |
| date | Date | Timestamp |
| is_update | bool | Whether allow automatic renewal |
In step S205, described first firmware version information and download address are encapsulated as upgrading command information.
In step S206, described upgrading command information is sent to described central control system by thread.
Here, central control system needs the network address translation through multilayer route to cloud server transmission message, message could be sent to cloud server.When central control system receives upgrading command information, the link of this multilayer route can not disappear, and returns upgrading command information by the address of carrying in datagram and the former road of port.
Central control system receives upgrading command information, and downloads from CDN.CDN is bottleneck and the link of avoiding the Internet likely affects data transmission bauds and stability as far as possible, make content delivery sooner, more stable.By placing one deck intelligent virtual network on existing Internet basic that node server is formed everywhere at network, CDN system can in real time according to the connection of network traffics and each node, load state and the request of user again to be led from the nearest service node of user to the integrated information such as Distance geometry response time of user.Its objective is and make user can obtain required content nearby, solve the situation of network congestion, improve the response speed of user's access websites.
CDN is the content distributing network be structured on network, rely on the Edge Server being deployed in various places, by the functional module such as load balancing, contents distribution, scheduling of central platform, make user obtain required content nearby, reduce network congestion, improve user's access response speed and hit rate.The key technology of CDN mainly contains content and stores and distribution technology.
The general principle of CDN extensively adopts various caching server, these caching servers are distributed in the area or network that user accesses Relatively centralized, when user's access websites, utilize overall load technology the access of user to be pointed on nearest caching server working properly, directly respond user by caching server and ask.
Further, described first firmware version information comprises version number, describedly from database, obtains the first firmware version information according to described version number and comprises:
From described database, firmware version information corresponding to described version number is searched according to described version number;
According to the timestamp in described firmware version information by described firmware version information temporally inverted order order arrange, using the firmware version information of sequence in first place as described first firmware version information.
Further, describedly described central control system is sent to comprise by thread described upgrading command information:
Described upgrading command information is put into transmit queue;
Described thread transfers described upgrading command information from described transmit queue, and sends to described central control system.
Further, also comprise: if the timestamp in described first firmware version information equals the timestamp in described second firmware version information, then do not need to upgrade.
Further, described message also comprises protocol type, locomotive state, real-time speed, real time electrical quantity and traveling total kilometrage.
Here, the information in message specifically can refer to table 3, as shown in table 3:
Table 3
A kind of auto-update device schematic diagram based on electric motor car central control system that Fig. 3 provides for the embodiment of the present invention.
Auto-update device comprises receiving element 10, acquiring unit 20, judging unit 30, checks unit 40, encapsulation unit 50 and transmitting element 60.
The message that receiving element 10 is sent by User Datagram Protoco (UDP) UDP for receiving central control system, described message comprises version number.
Acquiring unit 20 for obtaining the first firmware version information according to described version number from database.
Whether judging unit 30 is identical with the timestamp in the second firmware version information for judging the timestamp in described first firmware version information.
When checking that unit 40 is greater than the timestamp in described second firmware version information for the timestamp in described first firmware version information, check information-setting by user.
