Embodiment
Embodiment 1
The present embodiment provides a kind of method of electric power system data transmission, as shown in Figure 1, comprises the steps:
S1: mobile terminal is initiated connection request to message service system;
S2: after successful connection, described mobile terminal sends authentication data packet to described message service system, and described packet comprises No. imei of described mobile terminal;
S3: mobile terminal is by after the certification of message service system, and described message service system records No. imei and corresponding annexation of described mobile terminal;
S4: information data is sent to described message service system by operation system, described information data comprises and receiving and action data that this corresponding mobile terminal will carry out No. imei of mobile terminal of this information data;
S5: described message service system finds the annexation of corresponding mobile terminal according to No. imei in described information data, and described information data is sent to corresponding mobile terminal according to described annexation;
S6: corresponding mobile terminal is sent to operation system by the answer signal that whether successfully receives information data through described message service system according to described annexation.
For the information data that operation system is produced can be issued to mobile terminal in real time, the present embodiment has increased a message service system between operation system and mobile terminal.
In described step S2, described in be connected to long connection, described mobile terminal or described message service system can send continuously multiple packets under described long connection.The length of front four byte-identifier data of packet, data are xml messages, and the code field of data is mobile terminal No. imei, and long connection is used for frequent operation, point-to-point communication, and linking number situation too much.
Further comprising the steps of between described step S3 and S4:
Described mobile terminal sends a heartbeat request to described message service system at set intervals, if step S1 is returned in heartbeat request failure, described message service system is No. imei and corresponding annexation of the described mobile terminal of new record more; If heartbeat request success enters step S4.Heartbeat request is the command word oneself defining that the own state of the other side is notified in timing between message service system and mobile terminal, send and be used for judging whether normally operation of the other side according to certain time interval, adopt the simple communication bag of timed sending, if at the appointed time do not receive that the other side responds in section, judge off-line of the other side.For detection of the long abnormal disconnection connecting.Fundamental cause is that message service system can not effectively judge that whether mobile terminal is online, that is to say, it is for a long time in the free time that message service system cannot be distinguished mobile terminal, situation about still having gone offline.To be exactly the simple information of mobile terminal timed sending tell it me also to exist to message service system to so-called heartbeat request.Code is exactly to send a fix information to message service system every a few minutes, does not receive information of mobile terminal if message service system was received in fix information message service system a few minutes of rear reply, disconnects depending on mobile terminal.So just can keep the long availability connecting.
When the mobile terminal connecting with message service system is during at least two, message service system described in step S5 adopts Thread Pool Technology that described information data is sent to corresponding mobile terminal.Thread pool is a kind of multithreading processing form, in processing procedure, adds task to queue, then after establishment thread, automatically starts these tasks.Thread pool thread is all background thread.Each thread uses the storehouse size of acquiescence, with the priority operation of giving tacit consent to, and in multiple thread units.If certain thread is idle (as waited for certain event) in Managed Code, thread pool makes all processors keep busy another worker thread of insertion.If all thread pool threads all remain busy, but in queue, comprise the work of hang-up, thread pool will create another worker thread but the number of thread exceedes maximum never over time.Exceeding peaked thread can queue up, but they to wait until other threads complete after just start.
Like this in a fairly large number of situation of mobile terminal, message service system adopts Thread Pool Technology to send to mobile terminal efficiency and the real-time that information data can guarantee information data distributing, and the size of thread pool can be adjusted according to the quantity of mobile terminal.
After step S6, also comprise the steps:
S7: mobile terminal carries out corresponding operating according to the action data in described information data, is transferred to described operation system by operating result by webservice interface.
In described step S7, described mobile terminal adopts http agreement that described operating result is transferred to described operation system with the form of picture, recording file.Can make larger picture, recording file etc. also can correctly upload, avoid the internal memory of mobile terminal to overflow.
Technique scheme in the present embodiment, between mobile terminal and operation system, increase a message service system, between mobile terminal and message service system, connect, operation system has information data just can send to mobile terminal by message service system, break through the restriction that operation system can not initiatively not connect mobile terminal, realized operation system and sent in real time message to mobile terminal on one's own initiative, realized the command centre at operation system place and the repairing operation field at mobile terminal place visual, become more meticulous, interactive management.
