Abstract
The invention discloses an alarm, alarm method and alarm system, which consists of alarm and control center, wherein the alarm contains control unit and signal shield unit of cutting wireless communication. The control unit responds the register signal of alarm signal control shield unit and regards the register signal as warning occurrence. When control center inquires the warning occurrence, the system sends alarm according to register content.
Description
[technical field]
The warning system and the alarm method thereof that the present invention relates to a kind of alarm, form by this alarm.
[background technology]
At present, the mode of warning is varied, most of electronic alarms as shown in Figure 1, it is made of with the transmission medium that is connected them alarm host machine and supporting sensing element thereof.
Alarm host machine is responsible for receiving alerting signal that the warning sensing element sends and is given the alarm to the external world, and the mode that gives the alarm to the external world is divided into wired and wireless.Sensing element can be human body infrared inductor, door status switch, sense cigarette device etc., and transmission medium can be signal cable and radiowave.As forming warning net, also need a control center.
With regard to remote alarms, be divided into wired and wireless two classes.
1, wired alarming
The wired alarming system is divided into dedicated line and telephone line is reported to the police.
Dedicated line need set up the transport communication cable separately, so the class mode is not suitable for the large tracts of land networking, only suits to adopt in a building or residential quarters; Telephone line is reported to the police and is utilized the huge Local Network of just applying already, realizes remote alarms with lower cost, even can set up the remote alarms network.
Must depend on the phone networking because telephone line is reported to the police, therefore have certain limitation.For compensating its defect, people just use the radio alarming scheme being not easy to use under the situation of wired alarming system.
2, radio alarming
Radio alarming owing to be not subjected to the restriction of place, topography and geomorphology, is therefore paid attention to widely.But owing to limit by radio control, mostly be closely warning among a small circle greatly.The warning system scheme that has is provided with special emission, receiving trap, in order to forming own exclusive wireless alarming network system, the cost of can obvious this system paying is too high, only haves no alternative but, for example in the military base, ground such as large-scale noble metal mining area, otherwise not have the possibility of use at all.
Similarly be that the telephone line type of alarm utilizes telephone wire to reduce networking cost, wireless alarm system also should utilize worldwide largest, general at present wireless communication system one " mobile communications network " fully.
A kind of device that utilizes mobile communications network to send short message alarm is arranged at present, see Fig. 2.
It can send the alarming short message breath by the several mobile phones to appointment when alert takes place.The core of this radio SMS breath warning device is actually a mobile module circuit, has most of function of mobile phone, just can realize the remote-wireless warning with relevant warning sensing element cooperation back.But this device also has following deficiency:
1) price height is the same with the mobile phone price;
2) restriction that short message will be subjected to the short message rule is sent in operation inconvenience, and this machine is the same with regular handset, once can only send 70 Chinese or 160 English short message at most, and very inconvenience of its operation.Because this device does not have on the mobile phone keyboard and display as the I/O interface, content of short message that sends and short message receiving receptor's phone number and short message service center's number, by the RS-232 serial port be connected with PC and on PC operation or its is operated with other mobile phone just can deposit in the warning device.Main is that content of short message and recipient's phone number all is that internal code is represented mode, and promptly numeral will be imported the ASCII coding with English content, and what Chinese content of short message will be imported is the Unicode coding.Adding is replying of numberization entirely, and the layman can't finish basic setup at all, in operation of equipment today of hommization day by day, does not obviously have advantage to say.
3) inconvenient networking, networking requirement have a center control machine structure, and this mechanism can implement effectively control and management to affiliated terminal in the network.Because warning device can only be reported to the police in the mode of sending short message, unless in advance word content is made strict regulation, otherwise be difficult to the warning literal is done the control in a nearly step as the center control machine structure, can only be to concentrate to transmit short message, doing nothing so in all senses, can only be the burden that has increased communication network.So the class alarm all is independent use.
4) type of alarm is single
This device utilizes the sms center of mobile communications network to realize that the short message of warning message sends.Because cellphone subscriber's colony is huge day by day, and short message is lower owing to relative costs, and more cellphone subscriber has selected for use short message way to carry out contact communication.As the participation of festive occasion people's mutual congratulation, entertainment, advertisement in short message or the like, caused blocking up even may causing systemic breakdown of transmission network.During paid a New Year call the Spring Festival, the short message that sends may just be received after several hours.The basic demand of reporting to the police is in time to make things convenient for, short and small this feature that embodied just of alarm call number.If there are numerous these class mobile alarm devices in a city, catch up with the festive occasion and report to the police, then occur probably receiving the report for police service after the message, " thief " removed the building sky already.
Except that speed was slow, because the abuse (useless advertisement, note swindle etc.) of short message makes a lot of people not remove to check short message, the prompting mode of adding short message should not arouse attention, so the short message type of alarm causes probably and fails to report.
At present, in people's social life, also do not have a kind of real practical and effective alarming network system, can influence our life, make our environment that basic change take place.

Described registration signal with transfer table cut off be by frequency interferences mode, adopt and have shielding wireless communication signal materials with function and make the mode of shielding device or cut off the mode of the power supply of transfer table.
Described transfer table is mobile phone, PDA or other removable communication apparatus.
Control center of the present invention is made up of the database of a special disposal warning things of server Network Based, and the other parts of warning net are then fully by mobile communication network.Fig. 3 is the composition synoptic diagram of this network.Mobile radio communication in this synoptic diagram is an example with the GSM network that " China Mobile " adopts, as its principle of cdma network by its upgrading GPRS of system net or " CHINAUNICOM " all is.
The gsm communication network mainly is made up of network subsystem (NSS), base station sub-system (BSS), operation maintenance center (OMC) and a large amount of transfer table (MS) four parts.Wherein NSS is the core of GSM, it between the GSM mobile subscriber and the mobile subscriber play to exchange with communication between other communication network user and be connected and managerial role.NSS comprises mobile switching centre (MSC), VLR Visitor Location Register (VLR) database, attaching position register (HLR) database and AUC (AUC) etc.Wherein HLR is the central database of mobile communication system, deposits all data messages of contracted user, comprises authorization data, position data etc.The AUC of AUC is the safety practice that is provided with in order to prevent the disabled user from inserting gsm system.
The mobile alarm network system then adds that by GSM this five part of warning processing server (WS) forms.WS has write down the total data of the alerts user of registering, and comprises report to the police period, warning object code form etc.We can logically think and have two mobile communications networks, the GSM of Global Link system that forms by NSS, BSS, OMC and MS, and it provides well-known mobile communication service for us; Another then adds the mobile alarm network system that WS forms by NSS, BSS, OMC, MS, is responsible for the previous network user's alert service.Just the overwhelming majority in these two networks is public, and this common part has been finished by operator's investment construction of mobile communication, and has come into operation.
Therefore, play the GSM part of information transmission, exchange and management control function in this mobile alarm network, its technology, result of use are long-tested and undoubted.As a wireless alarming network system, its information is transmitted exchange system, and we are free the acquisition basically.
Mobile communication system is generally by transfer table (abbreviate MS as: i.e. mobile phone, PDA or other mobile signal equipment, other mobile signal equipment refers to add any transfer table that Subscriber Identity Module SIM/UIM constitutes by portable terminal), base station (BS), mobile services switching centre (MSC) and be used for junction line of being connected with public telephone network etc. and form.Each base station has the overlay area of oneself, can realize secure communication service in base station overlay area.The area of base station overlay area, mainly the antenna height by emissive power and base station determines.Mobile services switching centre mainly is the exchange of process information and the control and management of whole communication system.
The size of whole mobile communications network coverage rate depends on the areal coverage area of each base station and the quantity of base station, and jumbo mobile telephone system can constitute a mobile radio communication by a plurality of base stations.Just can be implemented in the intercommunication mutually between any two mobile subscribers in the whole service area by base station and mobile services switching centre, the process junction line is connected with local telephone network, realize communicating by letter between mobile subscriber and local user, finally constituted a wired and wireless mobile communication system that combines.
In system, all transfer tables after the energized all can by certain rule constantly near the base station its location register this machine information, this information can find by relevant signaling in whole net.
Real-time this machine information of registration has been arranged just, made that just the communication that produces is at random normally carried out.People usually can run into the answer of " shutting down " when dialing mobile phone, this is because mobile phone has sent log-off message to system when shutdown, so system makes answer like this for a side who desires with the mobile phone communication that has shut down; If mobile phone location exceeds network coverage or entering signal shielding area under the situation of start, when system can't get in touch with its foundation, because system does not find the log-off message of this machine, be " out of reach " so give desire and the opposing party's of its conversation answer.
During communication, in certain frequency range, mobile phone and base station couple together by radiowave, finish the transmission of data and sound with certain baud rate and modulation system.
Design of the present invention is: the so-called warning is the physical state that the parts that use of reporting to the police are presented, and defined in advance, and defining what state is that normal condition, what state should be alarm condition, and what kind of the mode that gives the alarm is.The present invention is according to reflecting alarm procedure as giving a definition:
Zero normal-as not send warning message, transfer table sends registration (contact) signal;
Zero unusual-generation alert (breaking out of fire, illegal invasion, opening of doors and windows);
Zero report to the police-sends signal, and transfer table interrupts registration (contact) signal.
Why the present invention adopts this method, be because in this scheme, the controlling alarm center can obtain the alerting signal that the mobile alarm device sends with very little cost, does not allow it see that specifying article specifies the easier realization of article than managing to allow it see as the sight line of blocking someone.The difference of alarm condition define method does not influence the accuracy that alarm is sent at all.Also just represent normal rest as Mr. A bedroom blackout, bright lamp represents to have alert to produce; And Mrs's B rest of liking turning on light is expressed as alert with blackout and produces equally accurate.It the phenomenon as the sort of networking of short message alarm obstruction can not occur yet, meets the principle of Cheap highly effective.More chief reason is, the work of a vitals of mobile alarm device is by being taken on by transfer tables such as the widely used mobile phones of people.
Because alarm will be used with transfer table, and transfer table (mainly referring to mobile phone) is to use very frequent equipment at ordinary times, in normal use the defined alarm condition of the present invention can appear also, so stipulated a time of fire alarming section among the present invention.Doing in the time period reports to the police handles, otherwise ignores.This turns off warning just as common alarm in the non-warning phase, be that closing on alarm of common alarm implemented, and the present networks system implements in control center.
So the principle of work of mobile alarm of the present invention system is: its pairing transfer table operate as normal (sending the registration signal) when alarm does not have alarm and produces, the registration signal cut of when the alarm alarm is sent, transfer table being sent to the base station to the base station.After alarm produces alarm, it is not to resemble give the alarm the traditional alert device (dialing the police emergency number etc.), it has cut off the registration signal that sends to the base station and has just notified control center to have alarm to take place, and will externally give the alarm by control center (calling, send short message, playback etc.).Whether system's (rather than alarm) externally gives the alarm, and will see also whether this transfer table is in the time of fire alarming section this moment.
The alarm of warning system of the present invention is sent and is divided into twice and finishes, and sees sequential synoptic diagram 4.Sequential 1 is the actuating of relay phase, that is to say the alarm switch signal of single-chip microcomputer according to difference input position input, the gating pulse of output different in width, and pilot relay moves during this period, and promptly the A of sequential 1 point is to the C point; Sequential 2 is the periodic signal of control center's inquiry mobile station login state, T=polling cycle; Sequential 3 is for registering the signal interruption time, and sequential 3 is from the beginning of B point effectively, and some A is that the actuating of relay makes screen unit start working systems inspection to shielding the time delay of coming into force to some B.B point in the registration signal interruption is the rolling counters forward phase during the C point.Control center is the binary counter of a m position word length of each warning transfer table setting during this period, is the cycle to carry out statistical counting with T.Obviously, its count value of alerting signal of the different inputs of single-chip microcomputer position is different, that is B point to C point is variable; Sequential 4 is greatest measure and signals in counter of variant categories within police force numerical value that counter can be counted; Sequential 5 has shown the pairing different categories within police force of the different count value of counter, corresponding again another kind of alert (as distress call) when being the corresponding a kind of alert (as fire alarm) of 0～a, a+1～b as the counter content ..., certain alert (as illegal invasion) during g+1～h.Numerical value h is the maximum count value of default, and this numerical value must be less than the max cap. (2 m power subtracts 1) of counter.
For example: the A point to the time that B is ordered be 6 seconds; Polling cycle T=0.5 second; Categories within police force is divided into 8 classes; Counter length is 16, and maximum count value is 65535.Can set a=8, b=16, c=24 ..., h=64 (a, b, c etc. are count value, can certainly be set as other value), the output pulse of single-chip microcomputer at this moment can be set lasting width by the above-mentioned time:
Categories within police force 1 10 seconds (+4 seconds countings of delay in 6 seconds)
Categories within police force 2 14 seconds (+8 seconds countings of delay in 6 seconds)
Categories within police force 3 18 seconds (+12 seconds countings of delay in 6 seconds)
Categories within police force 8 36 seconds (+32 seconds countings of delay in 6 seconds).Even consider the issuable error of counting, also can be easy to design the method for contrast categories within police force and accurately produce the pulse that drives relay work.
Therefore, the classification of alarm and generation are performed such: 1) send at the B point and point out alarm (as " there is something special ") for the first time, system begins to count, and counting finishes during to the C point.2) control center went to judge according to count value and belongs to any alarm after counting finished, and control center sends categories within police force alarm (as " fire alarm ") for the second time according to the content of registration then.3) as arrive we the institute predefined maximum categories within police force count value h after, the counting still proceed, promptly counter values at h+1 between the counter max cap..This obviously is that fault has appearred in the control module or the screen unit of alarm, and what cause that the mobile phone shielding signal do not stop sends.This situation is just sent the information of alarm partial fault.
Find out that thus warning system of the present invention not only can be reported to the police categorizedly, alarm self is also had fault inspection check and warning function.
Compare with traditional type of alarm, warning system of the present invention and alarm method have following effect:
1) networking cost is low
Cost has the implication of two aspects.At first from capital construction, equipment purchasing aspect, need not be as other private radio communication system, go to make up oneself launching tower station, communication apparatus etc., also need not as the wired alarming system, go trench digging, grooving to lay the communications cable.The communication base station of this cover system, switch control device is that mobile communication carrier has possessed, major part-transfer table in the alarm (mobile phone etc.) is that the user is existing, the network construction person only need purchase small number of devices such as warning processing server and get final product with mobile communication carrier signing related protocol (obtain the inner permission with the warning relevant information of user and this mobile radio communication under this mobile operator (as CHINAUNICOM), this mobile operator provides relevant application programming interfaces (API) for warning net establishment person and brings the profit sharing agreement of corresponding mobile income).As the investment of customer-side, except transfer table (mobile phone etc.), only need to buy a price and just can realize reporting to the police well below the mobile alarm device of traditional alert device.
On operation cost, type of alarm as the short message alarm tends to cause the networking to block even paralysis, though make the note revenue growth, therefore warning delay that causes and line traffic quality descend, and the user is reduced cause revenue decline.In our this warning system, alerting signal is in the mobile communications network internal extraction, and its expense is very cheap, speed is quick, the user is being collected under the situation of same service fee, and what service supplier's cost will be low is many.
2) extension of network is convenient
Connect with different mobile communication carriers, just intrasystem all mobile subscribers of this mobile communication operators can be included in the warning net.As the original agreement of signing of mobile alarm network, make warning net just provide alert service for " China Mobile " user with " China Mobile ".Through signing the agreement with " CHINAUNICOM " and after the information of carrying out is connected, also can allowing the user of " CHINAUNICOM " join the mobile alarm network system.The centralized control formula warning system of picture building, sub-district class all has certain restricted number to the quantity of alarm terminal, otherwise will change Centralized Controller.In whole mobile alarm network system, without any restriction, all legal mobile subscribers can apply for adding to the quantity of alerts user.
Except that the mobile subscriber, the telephone automatic alarm device of any one model originally, the special service number of a prior appointment that can be by dialing mobile communications network adds mobile alarm network system of the present invention.
3) mobility of Bao Jinging
Because warning system is based on the mobile communication operation, the areal coverage of so whole mobile communication all can be included alarm range in, domestic, international roaming function that mobile communication had, still effective to warning system, that is to say that warning system has the strange land warning function.As, " China Mobile " user of certain Shenzhen registration has carried alarm when going to Beijing, and has changed data such as new warning period and warning message transmission destination temporarily.Like this, when alert took place in its place that alarm is installed in Beijing, it just can receive warning message in interim guard station in Beijing.
Because roaming function has been arranged, make alarm range can expand to the whole nation even the whole world any one and we and be signed with the country of roaming agreement.The mobile alarm user can enjoy the mobile alarm service in any place that can normally use mobile phone.
4) scope of deploying troops on garrison duty is wide
Telephone alarm must be installed in the place of telephone line, and therefore under many circumstances, it is powerless that telephone alarm just seems.As the protection in the temporary building, the escorting etc. of the valuables of open field, mobile object (as automobile).In this case, the advantage of mobile alarm just displays more, and mobile alarm is not subjected to the restriction of place position, landform, landforms, can install and use very easily.Both can be in gate, bedroom also can be in remote places such as villa rusticas, in the mobile communications network overlay area without any the warning blind area.
5) installation is simply easy to use
The installation of traditional phone and radio SMS breath alarm is very complicated, and most alert datas such as purpose telephone number, short message content will carry out scene input and be provided with, this for the user who lacks operation training and no special knowledge, not a duck soup.And concerning the mobile alarm user, above-mentioned information has all been established when registering, even need interim change, also as the phone information service, is to revise to finish under the prompting of system voice.The user of this alarm uses operation very simple.After placing warning sensing element and alarm, the transfer tables such as mobile phone that are in holding state after the start are placed on the special position of alarm (main frame) get final product.
Because do not have specific (special) requirements,, two place's dwelling houses are arranged in a city as the user so can move use easily to installing and using the aspect, the A residence is that duration of work is lived, the use of spending holidays weekend of B residence, then he can be installed in alarm Monday～five in the B residence, installs and uses at the A residence when spending holidays.The startup of warning function is very simple, reserve the period of reporting to the police after, system can start automatically after the time.
6) type of alarm is many, the precision height
With traditional type of alarm ratio, the mode that the warning message of mobile alarm sends is more, to adapt to user's different requirements.Aspect definite alarm position, telephone call is incomparable especially, and telephone call can only be definite with the mode of phone registered residential address, as meets the phone migration and in time do not change the address, then can cause alarm set point to determine.
The positioning function that mobile alarm utilizes mobile communications network self to have can realize determining fast of alert locations, for responding is promptly and accurately laid a good foundation.The mobile operator that has at present (as the CDMA 1X net of CHINAUNICOM) behind the employing agps system A-GPS, can realize the three-dimensional localization of precision about 15 meters.That is to say that alarm can be sent the buildings on ground and accurately locate, the roughly floor of skyscraper also can be determined.If cooperate Geographic Information System GIS again, then can depict the landform, landforms on the ground of reporting to the police, highly, street and mark etc.Like this, where use regardless of the mobile alarm device is placed on, it can send alarm the position like clockwork and determine that handling for the police service of relevant department provides reliable guarantee.
Our this sets of plan is the transfer tables (mobile phone etc.) that existed in a large number already in order to adapt to, and scheme makes the cellphone subscriber under the prerequisite that does not influence original all functions of mobile phone, only needs input seldom just can realize the mobile alarm function.And the low cost that whole mobile alarm system forms, high-speed, high precision, convenience, comprehensive advantage such as simple and multi-functional, be the traditional alert mode can't compare.
Feature of the present invention and advantage will be elaborated in conjunction with the accompanying drawings by embodiment.

[embodiment]
Shown in Fig. 4-1, warning system of the present invention comprises the interface that is used to connect the warning sensing unit, control module, screen unit, control center, be used to connect the interface of warning sensing unit, control module and screen unit are formed alarm host machine or alarm, the warning sensing unit can be the human body infrared inductor, door status switch, sensing element and distress call buttons such as sense cigarette device, when it senses abnormal conditions (or pressing button), send a switching signal to control module, control module carries out exporting pulse control signal (the driving actuating of relay) after the respective handling, the action of control screen unit will be placed on the registration signal cut that the transfer table in its reach sends to the base station, think when control center inquires contact (registration) signal interruption of described transfer table in the Relational database of mobile communications network and the generation alert is sent by alarm according to the content of registering.Control module can mainly be made up of single-chip microcomputer and relay, also can mainly be made up of other combinational logic circuit and relay.The method that wireless communication signal is shielded has the cellular phone signal shielding device of use and deenergization operating mobile station power supply or radio shielding box.Transfer table adopts mobile phone usually.
Specific embodiment one, as shown in Figure 5, control module comprises the single-chip microcomputer 1 of order series connection, Sheffer stroke gate 11, buffer inverter 12, transistor 2 and relay 3, the input end of described single-chip microcomputer 1 links to each other with warning sensing unit 4, output signal is passed through Sheffer stroke gate 11 under the control of control end, phase inverter 12 links to each other with the base stage of transistor 2, the grounded emitter of transistor 2, collector connects power supply VJ by relay coil, diode of the reverse cross-over connection in relay coil two ends, a termination power VP in the normally opened contact of described relay 3, the other end is coupled to screen unit.When any one detects abnormal conditions in the warning sensing unit 4, the output high level signal is to single-chip microcomputer 1 input port, single-chip microcomputer 1 output signal (whether control is reported to the police and sent) under the control of control end signal makes transistor 2 conductings, after transistor 2 conductings, the current potential of the collector of transistor 2 is low, and power supply VJ is by collector, the emitter formation loop of relay 3 with transistor 2.Make the normally opened contact adhesive after relay 3 energisings, make screen unit energized VP.
Screen unit is a cellular phone signal shielding device, cellular phone signal shielding device (also have be called isolator, block device etc.), its principle as shown in Figure 6, this shielding device in the course of the work with certain speed from the low side frequency of forward direction channel to high-end scanning.This sweep velocity can receive at mobile phone and form the mess code interference in the message signals, and mobile phone can not detect the normal data of sending from the base station, mobile phone can not be set up with the base station connect.Mobile phone shows as phenomenons such as search network no signal, nothing service system, as get in touch with the answer to out of reach of meeting with its phone.Cellular phone signal shielding device many in the refuelling station, arenas, church etc. should not use the occasion of mobile phone to use, it can form radius is tens meters signal shielding district, because the mobile communication technology standard that adopts is more at present, so it is cellular phone signal shielding device also will be at these technical standards, therefore just comparatively complicated.Employed signal shielding device of automobile in our alarm only needs shielding to be encased in its inner or placement warning transfer table in its vicinity, and is irrelevant with other transfer table that is using.Therefore its emissive power is very little, as long as the shielding radius of formation has ten or twenty centimetre just can meet the demands, does not also need simultaneously the transfer table of various technical standards is shielded, and only need be selected to get final product according to the technical standard of conductively-closed object.So this signal shielding device is very simple, it selects the employed technical standard of conductively-closed object by the control of one group of switch, in this way still " Personal Handyphone System " etc. of " China Telecom " of " UNICOM " cdma network, " China Mobile " GSM network.The working power of shielding device is supplied with by the normally opened contact control of relay, and relay is by the warning output control of alarm.During the output of alarm free signal, relay does not have adhesive, and the cellular phone signal shielding device working power can not add, so unshielded signal produces; When alarm element was sensed the alert generation, the switching signal of output was with the relay adhesive, and signal shielding device powered operation according to the sensing of selector switch, constantly produces the shielded signal of this network standard.
Present embodiment also can be improved, and makes the corresponding different categories within police force of different mobile station login registering signal sections break period.The input end of single-chip microcomputer connects various warning sensing elements, and according to prior regulation, the sensing element of surveying different categories within police force is connected the different input position of single-chip microcomputer, and the output terminal of single-chip microcomputer drives the control wave of relay in order to output.Single-chip microcomputer carries out sending the pulse control signal (the driving actuating of relay) that width does not wait after the respective handling according to the difference of inductive switch signal link position, and the action of control screen unit will be placed on the registration signal cut that the transfer table in its reach sends to the base station.Increase counting unit, break period section and the corresponding tables of categories within police force in control center, counting unit can be with soft counter realization.When inquiring contact (registration) signal interruption of described transfer table in the Relational database of mobile communications network, control center thinks the generation alert, and determine categories within police force according to the data of categories within police force counter, the alarm of will classifying is then sent according to the content of registering.Counter also can be set a maximum duration, if mobile station login registering signal section break period exceeds maximum duration, then thinks the alarm fault.
The alarm flow of present embodiment is as shown in Figure 7:
1) user registers in control center, registration content comprises the individual subscriber data, time of fire alarming section (opening the beginning of warning, concluding time), (user changes later on and sets opening the beginning of reporting to the police access code, required during the concluding time), warning message sends means (mobile phone, local telephone network and internet), warning message send mode (short message, recording, Email etc.), warning message sends content (short message word content and recording substance), the classification warning message sends destination (telephone number, E-mail), shift telephone number (when having visit to be in the transfer table of warning period, other phones of transferring to) etc.;
2) the warning sensing unit detects abnormal conditions, and output switching signal is to single-chip microcomputer;
3) the single-chip microcomputer output signal under the control end signal controlling, export certain width pulse signal to transistor base, make transistor turns;
4) relay power makes the relay switch adhesive;
5) undesired signal is sent in mobile phone shielding device energising;
6) the registration signal of transfer table is cut off;
7) whether control center's registration signal of constantly inquiring about transfer table interrupts, and when the registration signal that inquires transfer table is cut off under the situation of not nullifying, as the alert prompting, picks up counting;
8) control center monitors and stops timing, the time period of calculating the registration signal interruption of transfer table when corresponding mobile station login registering signal recovers;
9) with the maximum duration section of time period of the registration signal interruption of transfer table and setting relatively, if the time period of the registration signal interruption of transfer table is greater than the maximum duration section of setting, think the alarm fault, if the time period of the registration signal interruption of transfer table is less than or equal to the maximum duration section of setting, then carry out step D;
10), determine the categories within police force of this alarm, and send alarm according to the registration content according to the section and categories within police force corresponding relation break period of predefined.
As Shenzhen " China Mobile " subscriber phone number is 138XXXX5678, and this user is moving for its mobile phone registration
Registration content is during alert service:
The time of fire alarming section
22:00～7:00；
Warning message send mode warning message sends means
Short message; Mobile phone;
Warning message sends destination warning message content
Fire alarm 138XXXX1234; Catch fire;
Robber and police XXXXXXXX; Rob;
Illegal invasion XXXXXXXXXXX; There is something special;
XXXXXXXXXXX is revealed in combustion gas; XXXXXX;
Someone gets over wall XXXXXXXX; XXXX; Or the like.
This user carries mobile phone in the time beyond the time of fire alarming section and goes out like this, when running into tunnel etc. and can't use the mobile phone place, reports to the police and can not take place.When being in its night mobile phone is placed on the alarm, as meets the fire alarm generation, number is that the mobile phone of 138XXXX1234 will be received the short message of " catching fire ".
Specific embodiment two, compare different with embodiment one be that screen unit is the shielding box that adopts material with shield radio signal performance to make, be useful on the cavity 6 of placing mobile phone in the described shielding box, described shielding box also comprises a dodge gate 7, the control signal that described dodge gate response control unit sends, design an office, when relay adhesive action is arranged, shielding box is closed with the shielding wireless communication signal, as shown in Figure 8, the figure on the left side represents the state that dodge gate is opened, and the figure on the right represents the state of dodge gate closure.
Specific embodiment three, as shown in Figure 9, comparing different with embodiment one, two is that screen unit is a change-over switch 8, embodiment three is small and exquisite transfer tables (communicator) of a no call function that is made of mobile module, a small amount of control circuit and SIM card, is exclusively used in the location and follows the tracks of.Described change-over switch 8 one ends connect the working power of transfer table, and two ends are respectively applied for the two ends that connect the relay normally closed contact by switching in addition, the relay normally closed contact a wherein end also be connected with transfer table.As shown in Figure 9, power supply 5 is to be switched switch 8 to control, and when switch pointed to communication one side, the work of transfer table energized was got in touch with normally with network.System is according to its positional information that constantly moves, for the client provides location-based various service; When switch pointed to warning one side, the working power of transfer table will just can add by the normally closed contact switch of relay 3.This relay 3 is by single-chip microcomputer and transistor output drive controlling, and during the output of alarm free signal, the normally closed contact of relay offers transfer table with power supply, produces normal cue.When alert takes place, export a switching drive signal, this switching signal disconnects normally closed contact the pilot relay action, thereby cut off the power supply of transfer table, can't operate as normal, can not produce normal registration signal, thereby be thought by system and to have produced alarm.
As seen, the alarm work task is very simple, only need manage when the warning sensing element has action signal cut or obstruct with transfer table, make transfer table not set up to get in touch and get final product with base station BS, and no matter adopt cellular phone signal shielding device to intercept that mobile station signal still cuts off the way of operating mobile station power supply and with mechanical shielding mode.
The alarm sensing element of Xiao Shouing can be directly used in mobile alarm device of the present invention with not adding any change in the market.These sensing elements are electronic switch signal or relay output mostly, and the output of the switch contact of this relay also has Chang Kai and normally closed two kinds of selections, can select for use easily with shorting stub.The work that we will do just suitably is connected electronic switch signal or relay contact with the single-chip microcomputer input end of alarm, be used for reporting to the police and mix transfer table when using again, just constitute a movable wireless alarm, and can form a huge warning net system that spreads all in the whole communications zone.
The retail price of these warning sensing elements has only about 20～40 yuans, and the price of therefore forming a mobile alarm device is dog-cheap, and this is 1/10th of a black phone alarm price! Thus, the mobile alarm utensil has high performance price ratio.
Safety problem is paid attention in current social very much, removes beyond the reinforcement of legal construction, and the means of safety precaution are more and more paid close attention to.It is reported that the consumption of domestic security product reaches 10,000,000,000 Renminbi every year, the numeral in the whole world is 50,000,000,000 US dollars.The related industry development is rapid, and only Shenzhen's this industry production value in 2003 is more than 200 hundred million yuans, the degree of visible product demand.But most alarms are solely to struggle against carrying out singles, and independent operating separately, but also can not popularize far away.Its reason is, also do not have so far a kind ofly can really form effective warning net scheme, and the alarm that can be accepted by the ordinary people of price correspondingly.
The appearance of mobile alarm grid will fundamentally be reversed for a long time electronic alarm by the situation of gentrification and marginalisation.China have at present surpass 300,000,000 be positioned at world-class cellphone subscriber colony, no matter network coverage still is that number of users is considerably beyond the Local Network.The network coverage contained cover small towns, mountain area, grassland and as far as 100 kilometers with interior marine site, we can say that mobile communication do not serve the blind area substantially.Mobile communication is inseparable with daily life, and promoting mobile alarm on this basis is the thing that when the water comes, a channel is formed.It will be accepted by all common transfer table (mobile phone) users and like that traditional telephone call user does not spend yet and worries to be ostracised outside warning net, and this alarming network system can hold all.Not hard to imaginely go out, if 300,000,000 mobile subscribers add in the mobile alarm service network, what it brought is a kind of which type of great variety.
Being extensive use of of mobile alarm can promote the progress of electronics manufacturing.If there is the transfer table manufacturer to cooperate the mobile alarm network, produce relevant multi-functional mobile phone of reporting to the police; Or provide the mobile phone SIM/UIM card of such two card functions of similar dual-mode handset, card even numbers, an one-card multi-number cell-phone function.The function of mobile alarm system is more powerful with making, and the price of alarm is cheaper, uses convenient, universal.After the secondary development of mobile operator, can derive diversified propagation alert service, make our living environment safer.
The mobile alarm network system is suitable for publicization of alert service more, and it can provide more information for safety office than traditional alert mode, and public security department has it and will lay a solid foundation for the foundation of interlink alarm system.
Can say so, in the mobile alarm network, not have thing that what is in complete secrecy again, under its supervision control, all will be transparent.And the enforcement of everything need not be laid the one-inch cable, and we seem not have to change at the moment, but have been the another one world fully!
