[embodiment]
Be illustrated in figure 1 as a monitoring alarm network system based on internet (Internet) technology.It is formed by alert central processing unir (webserver) by the terminal alarm of any amount and one, the terminal alarm can support all circuits that can be communicated with internet (Internet) to carry out communication with being subjected to alert central processing unir, as: LAN (Local Area Network), telephone wire, cable of cable TV etc.
The terminal alarm is that the intelligent electronic device that connects various known warning devices can be installed, and its major function is that the alerting signal that will collect is sent to the center of receiving a crime report and accepts control command execution unit is carried out control operation.
Network backbone is ChinaNET (also can be any backbone network), and the node in the network is the server of certain LAN (LAN (Local Area Network)), and its inner composing method may have very big difference between the different LAN.The last point of in the network each (terminal) is a station terminal alarm, and the mode that they connect network is different because of the difference of Load Line.The telephone line alarm links to each other with access server (referring to provides the access Internet service for the device of phone dialing mode networking) by dialing; Line sharing (ISDN, ADSL) terminal alarm directly links to each other with ChinaNET (China Public Computer Interconnection Network); Electric supply line and Cable MODEM terminal alarm link to each other with the relevant ISP server; Optical fiber information socket links to each other with the server of certain Virtual network operator; And in the sub-district of the warning system that other has built up, mansion, campus, its alarm separately is connected with the duty room control center of own system or such as the server of CERNET (CERNET), CSTNET (CSTNet) already.But as long as duty room control center computer or LAN (LAN (Local Area Network)) server have inserted internet (Internet), can with the information processing centre of our this system--be subjected to alert central processing unir (webserver) to carry out message exchange.It is not concrete network on the structure, and it is interconnected with all kinds of (different medium, different structure) physical network, and realizes communication between them by upper-layer protocol.
Formed by high-speed electronic calculator, printer, large screen display and a corresponding monitoring and control management software system that has big capacity hard disk by alert center.Its effect is the central processing unir (webserver) of this warning net, says to be exactly warning website, city from the angle of internet.Be subjected to alert center to also have access server, for the dial-up terminal alarm provides the access network service.For example, the address of website is WWW.City Warn.gov, and dialling in number is 100.Why that network address is open, be because the user also can control the work (alerting signal is sent alarm sound except that mailing to the phone that is subjected to also can reserve for the user in advance automatically the alert department, and the user also can command the household equipment work by the internet) of relevant device by the internet.
The network address is a kind of global resource, and it is in global unified addressing, and different countries, different cities and its address of ISP are all different.Computing machine is when installing network driver in the internet, above-mentioned parameter and host-host protocol, dials in number etc. and all will be provided with.
For our this warning system, the number that is subjected to the alert webserver and access server in different regions and city is different.But system requires again the network address of server must be set in the terminal alarm or dial in number, and for a terminal alarm that does not almost have the person-machine dialogue means, the on-the-spot setting is very difficult.For this reason, we can only will be solidified the numbering (ID) of terminal alarm self when dispatching from the factory in advance one by one, and country, city, server, dial in parameters such as number and host-host protocol, or select to adjust by the shorting stub that is provided with in the machine; Configure in advance when producing and solidify, but this nonadjustable usable range that has limited it that is provided with.
Central processing unir (webserver) is set up account information for each terminal alarm, alarm mails to central processing unir with alerting signal to be fetched simultaneously by being subjected to alert operating personnel or user to issue the control command of terminal device, and this command execution of a tree name is operated accordingly.The terminal alarm is except that the tool warning function, can accept the order of the execution control housed device work that the user sends in any place, its adopts the method for regularly interrupting to be connected with server, fetches control command and carries out corresponding order when the time comes according to given time, date.
Central processing unir has particulars such as the block number such as accurate positioning address, occupant's details, indoor storage goods, the location drawing of whole terminal alarms in this warning net.The alerting signal that the terminal alarm is sent is received by control center, according to information such as Unified coding, alarm classifications, for the operator on duty that receives a crime report shows the relevant information of spot and can print topomap as required, uses for responding.
Because essential, in management, give different control authorities according to different ranks, some alarm can only accept to be subjected to alert operating personnel's instruction, certain some to can intervene by secret key.Some maloperations and malicious operation have so just been avoided.
Checkout equipment can be made up of magnetic switch, sense cigarette and combustion gas detection, infrared induction element and video camera etc., in order to forecast fire, detection combustion gas leakage, distress call, perception illegal invasion and invasion number, the said equipment has been widely used and has been easy to and buied.
The end of incoming cables of terminal alarm connects various checkout equipments and pushbutton switch (in case of emergency call for help and use), and leading-out terminal is connected on phone, camera cable and the power lead.It is the touring test pick-up unit that core constitutes with the microcontroller that this machine is one, detected abnormal results is sent to central processing unir and by the command execution of central processing unir such as opening gamma camera, open spray, spraying action such as gas closed shutter so that check picture, control the condition of a fire, drive and subdue the invador.The situation that the terminal alarm is looked subscriber's line and existing equipment can have the different choice type.
