Description
Technical field
The present invention relates to a kind of data switching networks device, in particular to a kind of monitoring arrangement of data switching networks.
Background technique
Currently, the alarm of networked Digital Video Monitoring System both domestic and external generally uses local sound-light alarm, it is long-range to report
Alert then be wired alarming (such as fixed-line telephone alarm), this plays a role to general criminal is taken precautions against, but to prevention internal staff
Crime, by cutting alarm probe, video camera, so that the method for cutting telephone call line and monitoring host computer power supply line carried out
Any profession is destroyed, and the paralysis and failure of monitoring system will be caused.In this way, being referred to as " interior guarantor " takes precautions against asking for internal staff's crime
Topic not yet solves.Such as " the interior guarantor " of bank vault, it is desirable to must to criminal cuts alarm probe, video camera, so that cutting
Power-off telephone alarm line and monitoring host computer power supply line carry out non-wired remote real-time monitoring, and the prior art is not met by this want
It asks.
Summary of the invention
The purpose of the present invention is to provide in monitoring site by cutting alarm probe, to take the photograph prevention internal staff's crime
Camera, so that cutting telephone call line and monitoring host computer power supply line method carry out it is any profession destroy, realize it is non-wired
Interlock type remote real-time monitoring.
A kind of networked Digital Video Monitoring System with wireless alarm provided by the invention, the system include alarm
Probe, video camera, monitoring host computer, LAN switch, wireless alarm and ups power, the monitoring host computer respectively with alarm
Probe, video camera are connected with ups power, and the wireless alarm connects with alternating current 220V power supply and passes through exchanging in local area network
Machine is connect with alarm host machine.It is connect if the wireless alarm also passes through China Mobile's GPRS network with cadre's mobile phone.
A kind of networked Digital Video Monitoring System with wireless alarm provided by the invention, wherein wireless alarm
Integrated backplane is connected to network communication interface, serial communication interface, GPRS antenna port, alternating current 220V power port and board hardware
Port, and integrated the single-chip microcontroller of insertion with bottom plate by board hardware port.
When the monitoring host computer timing (adjustable) of monitoring site sends status frames to wireless alarm, wireless alarm passes through net
Network is differentiated automatically after receiving status frames, then continues to new status frames if normal；Pass through GPRS net if being abnormal
Network sends alarm message breath or realtime graphic to system specified ground operator on duty's mobile phone channel.That is, working as monitoring site: a alarm is visited
There is alarm signal in head, and the vision signal of b video camera is lost, and c monitoring host computer is in video detecting, when there is object to invade video camera
Reconnaissance range and start video detecting alarm, when d monitoring host computer powers off, wireless alarm will send warning message or realtime graphic
To mobile phone channel, and warning message is pointed out to alarm all the way specific to that, and upper level monitoring center can be transmitted in video image.
When monitoring host computer cannot connect to wireless alarm, the automatic alert in monitoring host computer end is prompted on duty
Member's wireless alarm may be destroyed.
The present invention compared with prior art the advantages of, be to change the backwardness side of only local alarm and wired alarming
Formula realizes the GPRS network radio alarming communication of warning message.This GPRS network information between single-chip microcontroller and mobile phone is logical
Road interlock type alarm technique, there has been no precedents at present.
It is described in detail below with reference to embodiment referring to attached drawing, in the hope of being obtained to objects, features and advantages of the present invention
Deeper into understanding.
Detailed description of the invention
Fig. 1 is the block diagram of inventive network digital video frequency alarming monitoring system；
Fig. 2 is the block diagram of wireless alarm of the present invention；
Fig. 3 is the flow chart of wireless alarm data processing of the present invention.
Specific embodiment
The embodiment that the invention will now be described in detail with reference to the accompanying drawings.
Referring to Fig.1, the networked Digital Video Monitoring System with wireless alarm includes alarm probe 1, video camera 2, prison
Control host 3, LAN switch 4, wireless alarm 5 and ups power 6, the monitoring host computer 3 respectively with alarm probe 1, camera shooting
Machine 2 and ups power 6 connect, and wireless alarm 5 connect with power supply 7 and connected by the interchanger 4 in local area network with alarm host machine 5
It connects, if also being connect by China Mobile's GPRS network with cadre's mobile phone 8.
Referring to Fig. 2 and Fig. 3, the data handling procedure during the present invention will be described in detail is as follows:
Wireless alarm 5 includes integrated backplane 50, network communication interface 51, serial communication interface 52, GPRS antenna port
53, alternating current 220V power port 54, board hardware port 55 and single-chip microcontroller 56.
Single-chip microcontroller 56 carries out parameter setting and definition setting, including program parameter, communication network parameters first after actuation
Macrodefinition and alert process function are distinguished with operation macroparameter, the definition of state frame format, the definition of GPRS information format, type of alarm
It defines (step 5611 and 5612).Then program initialization is carried out, including GSM is initialized when initializing and establish with alert data
It unites (step 5613 and 5614).
Later, single-chip microcontroller 56 establishes the connection with the network switch 4, to receive the status frames that monitoring host computer 3 is regularly sent
(step 5615).Then, network state frame (step 5616) is received in setting time (in adjustable), whether detection receiving time surpasses
After setting time (step 5617), if testing result is less than the setting time and receives successfully, reading state frame (step
5618)；If testing result is failed, it is confirmed as monitoring host computer power alarm, chooses corresponding operator on duty's mobile phone channel number,
Send specified short message (step 5623).After reading state frame, then detected whether for alarm frame (step 5619), if inspection
Survey result be it is yes, then carry out alarm frame type and content confirmation, i.e., confirmation warning message number, short message number and accordingly
Person on duty's mobile phone channel number, and start short message or Realtime Alerts image transmission (step 5620).If testing result be it is no,
It returns and receives new status frames (step 5616).After the sending of the above warning message, start timing, the time is more than detection after 30S
Alarm whether still have (step 5621 and 5624), if testing result be it is yes, continue alarm (step 5621 and 5624)；If
Testing result be it is no, then return and receive new status frames (step 5616).
The board hardware single-chip microcontroller that wireless alarm of the present invention uses is small and exquisite, embeds compact software package, has very
High calculating density, size are only the size of 3.2 " * 2.3 " i.e. one credit credits card, and starting, test and maintenance are extremely
It is easy.
Present networks digital video frequency alarming monitoring system also has the function of further to extend.It can be established in monitoring in city
The heart is connect by GPRS communication channel with all wireless alarms.
Present networks digital video frequency alarming monitoring system, in addition to the real time monitoring for bank vault, in seismic monitoring, atmosphere
Environmental protection tests (such as boiler emission), gas distributing system monitoring and public security department, security department, customs, People's Armed Police, forest fire protection,
Traffic guidance, highway, hydrometeorology, harbour, warehouse, military installations digital picture and data numerous necks such as real time monitoring
Domain has been widely used.
