Further, warning device in real time with management platform and client more new state information, the state letter of warning device
Breath includes: in the free time, in alarm neutralization intercommunication.
Warning device is after receiving " seat is idle " state reporting request that management platform is replied, and state is by " in the free time "
It is changed to " in alarm ", and reporting equipment Status Change requests to give management platform.Management platform receives the shape from warning device
After state change request, it is transmitted to corresponding subscription client.After client receives alert and equipment state alteration command, shape is updated
State and showing interface complete alarm report flow.
After warning device establishes video link and voice frequency link, state by being changed to " in alarm " " in intercommunication ", and on
Equipment state change request is reported to give management platform.Management platform receives the equipment state change request reported from warning device
Afterwards, it is transmitted to corresponding subscription client, client more new state, completion establishes video link and voice frequency link with client
Process.
After warning device recycles video link and voice frequency link, state " in intercommunication " by being changed to " in the free time ", simultaneously
Reporting equipment Status Change requests to give management platform.Management platform receives the equipment state change request reported from warning device
Afterwards, it is transmitted to corresponding subscription client, client more new state terminates process of receiving a crime report.
Warning device after reporting alert, if setting time (normally 60s) interior client do not receive a crime report or
Warning device do not receive come Self management platform response message cause alarm time-out, warning device send alert Status Change ask
Management platform is sought, while warning device state, by being changed to " in the free time " " in alarm ", warning device sending device state becomes
Management platform is arrived in more request.After management platform receives alert Status Change request, the corresponding resource of recycling alert simultaneously updates alert
State, receive after the change request of equipment state that warning device reports, be transmitted to corresponding subscription client, client
More new state completes the recycling of resource.
During receiving a crime report, lead to time-out of receiving a crime report (such as " media link interruption ") for some reason, warning device is sent
Alert Status Change request is to management platform, while warning device state is by being changed to " free time in " " in intercommunication ", warning device
Sending device Status Change is requested to management platform.After management platform receives alert Status Change request, recycling alert is corresponding
Resource and the state for updating alert receive after the equipment state change request that warning device reports, are transmitted to corresponding order
Read client, client more new state, the recycling after completion alert is overtime to resource.
Further, the state of warning device further includes " in alarm ", when client draws alarm, warning device Status Change
For " in alarm " state:
Client sends to management platform and draws alert request, after management platform receives the drawing alert request from client,
Be transmitted to corresponding warning device, warning device receives carry out the drawing alert request of Self management platform after, state is become by " free time in "
More " in alarm ", while reporting equipment Status Change requests to give management platform.Management platform is received to be reported from warning device

Embodiment one
Embodiment one provided by the invention be a kind of key alarm system provided by the invention in alarm, receive a crime report in and it is alert
System Fault Tolerance processing method when state in report is illustrated in figure 2 the structure of the embodiment of key alarm system provided by the invention
Block diagram, as shown in Figure 2, management platform includes: NMS (Network Management Server, NM server), CMS
(Central Management Server, center management server), VTDU (Video Transfer&Distribute
Unit, media forwarding server), ALS (Alarm Server alarm server), NRM (Network Record Manage record
As management server), NRU (Network Record Unit record a video storage server) and AVS (Audio Video
Steaming Sever playing back videos server).Module between platform is realized using SIP+XML mode, by SIP
MESSAGE method realizes the interaction between module.Communication network is supported through IP networks such as education network, 4G wireless network, public security nets
Network realizes data transmission.
Warning device to management platform alert after do not enter into alarm in state when, System Fault Tolerance processing includes
Several situations below:
1, equipment and platform network are obstructed
Equipment is repeatedly registered to platform, but can not succeed in registration, and illustrates that current ink has broken down, and equipment mentions when alarm
Show " link failure ".
2, CMS is not online
If warning device has detected CMS and has gone offline, and warning device can be mentioned by way of prompt tone during alarm reports
Show " system failure ", at the same warning device can be considered by other links report alert (if in some cases with platform
Link break down, can reserve and other ensure that links are reported, it is ensured that business not will receive large effect).
3, CMS is restarted
Step 1: dealing of abnormal data, the alert being in alarm in database is inquired, located in the following several ways
Reason:
If it has been more than the time-out time (180s) of system default that alert, which reports and submits the time,；
If equipment is offline；
If there is a plurality of untreated alert under an equipment, retain newest alert；
Above several situations think that alert has timed out；
Step 2: equipment state is synchronous, the alert being in alarm in database is inquired, to equipment initiating equipment state
Inquiry request (ALARMDEVICE_STATE), if equipment is in alarm and in current corresponding alert number and management platform
Warning numbering be consistent, alert is added in timer, it is normal to handle；If equipment state is inconsistent, alert is set to
Time-out；If equipment state is consistent but alert number is inconsistent, it is believed that equipment has reported new alert, and alert is entered into system
In, and other submodules (such as ALS, CU) are issued to, it is normal to handle, and alert before is set to time-out；
For the alert in alarm, due to receiving a crime report not yet, the concern person's of receiving a crime report state synchronized processing can not had at this time.
4, ALS is not online
When ALS is not online, it can guarantee that alert can be reported normally using strategy in following 2:
By the way of two-node cluster hot backup, if main ALS is not online, starts standby ALS and pushed；
If it is not online that CMS detects ALS, directly broadcasted by CMS.
5, client (CU, Client Unit) is not online
Platform judges whether there is corresponding seat according to the number of the currently person of receiving a crime report, warns if handling without corresponding seat
Feelings, to the corresponding instruction of device replied, device prompts " system is busy, please tries again later ", without corresponding seat.
6, CU still receives a crime report without the processing of corresponding seat online
When client is online, but (such as person of receiving a crime report A and B only has the power of region C since alert push is associated with region
Limit, when the equipment report and alarm of region D, system is received a crime report without the corresponding person of receiving a crime report at this time), " system is busy, please slightly for device prompts
It tries again afterwards ".
7, it after client receives alarm, does not receive a crime report, exits extremely
Due to not receiving a crime report, such situation can not have to processing.
Warning device enters in alarm after state, manages platform at this time and signaling link, media chain has been established in warning device
Road needs to consider the recovery of link, System Fault Tolerance processing includes following several situations if any one link breaks down:
1, CMS is restarted
When CMS is restarted, the signaling link managed between platform and warning device has interrupted (session has been not present), due to
There are link-recovery mechanism by CMS and VTDU, can carry out link-recovery, while restoring link, need to restore alert, this is just needed
Want CMS handle alarm when alert and media link needs be associated (need conversate invite i.e. transmission INVITE when,
Carry alert number AlarmID), alert can remain consistent with original process after being successfully recovered.
2, VTDU is restarted
When VTDU is restarted, media link is closed, and CMS needs to do at reconnection alert while closing signaling link
Reason, if alert interrupts, push is prompted to corresponding client and carries out " clawback " operation, at the same notify front end prompt " link failure,
It is try to restore, please wait a moment ".
3, CU is restarted
When client is being received a crime report, for some reason (such as network interruption), cause to restart, server does not have in alert
In the case where time-out, PUSH message to the client, Client-Prompt " leads to exception, if restore police for some reason
Feelings " by way of clawback, re-establish new link after client confirmation.
4, warning device is restarted
When warning device is restarted, link is reset, and management platform needs to recycle link, while the shape of synchronous warning device
State, and corresponding client is broadcast to realize the synchronization of state.
After CU draws alarm, exiting extremely or due to network is unsmooth etc., warning device is not normally received stopping police
The message of report causes warning device that can be constantly in alarm, and alarm can not stop.In order to ensure the normal release of resource, by
CU timing (interval 10s) sends to CMS and maintains alert message, which is passed through warning device by CMS, remains alert with this
Report.It is confiscated when warning device continuous 3 times and maintains alert message, just stop alarm, and to CMS reporting equipment state.
In addition in terms of application displaying, when equipment is in alarm, CU needs can know that the alarm is who is initiated.
In order to guarantee the uniqueness of alarm, platform adds SN mechanism (miosSN) in the management of alarm, i.e., when certain CU initiates primary police
The message is issued CMS by CU, after unique No. SN is generated inside CMS and fills IET_SN field, which is transmitted to alarm by report
Equipment, warning device need subsidiary this No. SN to return to CMS when replying RESP, CMS judges that this RESP is corresponding using this No. SN
Be which alert request.The meaning of addition SN mechanism is: avoiding when network is unsmooth, CMS is initiated to warning device
Alert request A, in the case where failing to receive the RESP of warning device reply in time, CMS has initiated alarm to warning device again
B is requested, then has received the RESP of warning device reply, it is which of A and B are asked that it is corresponding that the RESP just cannot be distinguished at this time
It asks.
In conclusion being divided into following several situations when equipment is in alarm to carry out System Fault Tolerance processing:
1, warning device side
A) warning device is restarted: warning device meeting uploaded state, therefore does not have to specially treated；
B) warning device receives multiple alert message: referring to when user initiates unlatching alarm to the equipment in alarm again
When enabling, which is passed through warning device by platform, and equipment should refuse new alarm, and carry mistake in response message
Error code.
C) alarm maintains message to mismatch: equipment, which receives, maintains alarm types and current lasting police in alert message
When type being reported to mismatch, equipment thinks that the maintenance alert message is invalid, is equivalent to CU and does not have activating alarm to maintain message, and disappears in response
Error code is returned in breath.
2, CU is restarted
Platform, which is actively sent out to equipment, stops alert message (record of CU alarm is saved in database)；
3, CMS is restarted
Alarm state is respectively maintained by CU and warning device.(CMS transparent transmission alert message and database of record)；
4, network state is bad
The CU that (equipment and platform) equipment confiscates platform forwarding goes off the air message；
(CU and platform) platform confiscates CU and goes off the air message；
It is sent from CU timing (interval 10s) to CMS and maintains alert message, which is passed through warning device by CMS, with this
To maintain alarm.It is confiscated when warning device continuous 3 times and maintains alert message, just stop alarm, and to CMS reporting equipment shape
State.

Embodiment five
Embodiment five provided by the invention is the processing in a kind of key alarm system provided by the invention under timeout case
The embodiment of process is illustrated in figure 6 client in a kind of key alarm system provided by the invention and receives a crime report the embodiment of process
Flow chart, it will be appreciated from fig. 6 that alarm time-out when, steps are as follows:
Step 501: warning device is after alarm, and (normally 60s) alert is not received a crime report in a period of time, report
Alert equipment thinks alert time-out, sends alert Status Change request to management platform, while warning device state is by " in alarm "
Become " free time ", sending device Status Change request to management platform；
Step 502: after management platform receives alert Status Change request, the corresponding resource of recycling alert simultaneously updates alert
State receives after the equipment state change request that warning device reports, is transmitted to corresponding subscription client, client is more
New state, resource reclaim finishes after alert is overtime.
When time-out of receiving a crime report, steps are as follows:
Step 601: after alert is received a crime report, video link and voice frequency link are established between warning device and management platform,
If leading to equipment detection media link time-out (realizing by detection RTCP) for some reason, equipment thinks alert time-out,
Alert Status Change request is sent to management platform, while the state of warning device, from becoming " free time " " in intercommunication ", transmission is set
Standby Status Change is requested to management platform.
Step 602: after management platform receives alert Status Change request, the corresponding resource of recycling alert simultaneously updates alert
State receives after the equipment state change request that warning device reports, is transmitted to corresponding subscription client, client is more
New state, resource reclaim finishes after alert is overtime.
After ensuring that alert normally reports, due to do not receive a crime report normally or module break down, cause in the mistake dealt with emergencies and dangerous situations
When journey is interrupted, resource can be recycled rationally, while the state of each network element of platform is able to maintain synchronization.
Alert time-out is mainly generated in above several situations:
1, warning device in alarm (after alert reports, not received a crime report, belong to normal time-out, be defaulted as 60s), receive a crime report
In (media link between platform detection time-out is RTCP time-out) think that alert time-out, equipment send time-out instruction to management
Platform, notice alert have timed out, while sending warning device Status Change instruction, more new equipment state.
2, CMS thinks link time-out, normally due to client, equipment end cause alert not handled normally extremely
Finish, server can think alert time-out in 180s, update alert state, while notifying client and warning device, warning device
Receive time-out instruction after sending device Status Change instruct platform to management, more new equipment state.
3, CMS is for the client and alarm in receiving a crime report, if a side occurs going offline during receiving a crime report, restart
Phenomenon, server need for alert to be set to time-out, while notifying client and warning device more new state.
4, when client thinks alert time-out, being reported to management platform, (client thinks that the situation of alert time-out generally limits
In 10 minutes, network of the client timeout mechanism generally between platform and client can be opened system when breaking down).
Normal alert timeout treatment process is as follows:
Alarm host machine sends the instruction (ALARM_NOTIFY) alarmed to management platform first；Timing is sent to management platform
Session of alarming continues instruction (ALARM_HEARTBEAT), and carries session effective time；It is preceding if the person of receiving a crime report does not receive a crime report
Hold active transmission time-out instruction (ALARM_TIMEOUT).
Abnormal alert timeout treatment process is as follows: alarm host machine sends the instruction (ALARM_ to alarm to management platform first
NOTIFY)；Timing to management platform send alarm session continue instruction (ALARM_HEARTBEAT), and carry session it is effective when
Between；If the person of receiving a crime report does not receive a crime report, front end active transmission time-out instructs (ALARM_TIMEOUT), but manages platform and do not receive
It arrives.ALARM_HEARTBEAT is not received in management several sessions of detection of platform, it is believed that session timeout.
In above several situations, once alert state changes, if warning device thinks alert time-out, use
ALARM_STATUS instruction notification manages platform, and management platform is broadcast to corresponding client change alert state, sets with alarm
Management platform, more new equipment state are given for needing sending device Status Change to instruct；If management platform thinks alert time-out, use
ALARM_STATUS instruction notification client and front end, update alert state, warning device after the instruction for receiving alert time-out,
Link is terminated, sending device Status Change, which instructs, gives management platform；If client thinks alert time-out, using ALARM_STATUS
Instructing to management platform reports alert overtime, and management platform notifies other clients and front end, updates alert state, and equipment exists
After the instruction for receiving alert time-out, link is terminated, sending device Status Change, which instructs, gives management platform.
Due to need to realize alarm session continuity (if certain primary alarm i.e. will time-out, user can press by alarm again
Button continues session), the time of heartbeat therefore the chronograph mechanism for managing platform needs to be subject to finally to alarm.
