In order to solve limitations of communication in conventional monitoring method such as low coverage, single mode, high cost and no interactivity, the invention transmits various monitoring instruction and information between the monitoring object side and the monitoring platform side via a USSD (Unstructured Supplementary Service Data) which is established after the monitoring object side is triggered, and meanwhile, a user can perform positioning, monitoring and related information value-added service on the monitoring object side via a radio communication terminal or a computer on internet.
Description
Technical field
The present invention relates to remote wireless monitoring technology, LBS network positions technology, wireless communication technology, the network communications technology, software engineering, specifically be meant interactive positioning and monitoring method and system based on cordless communication network.Belong to areas of information technology.
Background technology
At present, known wireless location and supervisory control system are meant: GPS operator utilizes GPS (GPS (Global Position System)) technology that the system of locating and monitoring service is provided to this professional user.
At first, position and monitor, must build the locating and monitoring center with GPS.The construction cost of Surveillance center is huge, and an operator has only one usually in the Surveillance center that a large size city is built.Therefore the individual can't directly use Surveillance center, and the system user or the owner can not become direct monitor, and monitoring Fang Ruxu positions and monitors monitored side, must (usually by making a phone call) seek help as third-party Surveillance center.Even GPS operator uses connection (Taiwan new technologies in 2005) for the specific WEB that the user has opened client, the user also must finish by operator the location and the monitoring of monitor terminal, let alone the user carries out long-range policer operation and other application service by portable mobile phone.So the GPS locating and monitoring can not realize that the user is autonomous, interactive, safety, point-to-point location and monitoring.
Secondly, GPS belongs to the terminal positioning technology, in GPS location and supervisory control system, the locating information of GPS (longitude and latitude), remote signalling and other monitoring feedback information, produced by monitor terminal, the present overwhelming majority of this part information passes back to Surveillance center by public's wireless communication networks (GSM/CDMA/PHS).This will produce the problem of two aspects again:
1. for navigation system, the positional information (longitude and latitude/height above sea level) of monitored side's monitor terminal recipient generation via satellite must be transferred to Surveillance center and finish map contrast and analysis.Therefore, system will use two wireless networks simultaneously for the application of location: the firstth, and the GPS fixer network; The secondth, the signal transmission network of radio communication.So the efficient working range of navigation system will be decided by the common factor of these two wireless networks, and this two non-overlapping of throwing the net network has caused the limitation of navigation system working range.
2. for supervisory control system, owing to will carry out two-way policer operation, feedback information and control command all must be transmitted by cordless communication network, and current now way is to carry out the remote signalling transmission by SMS (note) and GPRS (General Packet RadioService).But, can not guarantee service quality because the connection-oriented business of note right and wrong usually is subjected to the influence of time delay.For the connection of GPRS, though can guarantee onlinely constantly, coverage is not as good as the GSM network; GPRS charges according to flow on the other hand, and expense is higher, and especially for frequent or accurate Industry Control, its communications cost is higher, has influenced the employing and the popularization of this technology.
(writing China Construction Industry Press referring to " GPS location technology " Shen Xuebiao etc. publishes)
This shows, the generation of present GPS locating and monitoring system locating information is the end side at locating and monitoring system, the data communication connection of locating and monitoring and the initiation of control request and be the monitoring platform side, the data communication connected mode of this system has only SMS and two kinds of approach of GPRS simultaneously, does not have better to realize high performance-price ratio communication connecting method frequent, the small data quantity exchange at present.Although, a lot of limitation are arranged still so the GPS locating and monitoring system is of many uses.
Summary of the invention
In order to address the above problem, the present invention aims to provide a kind of interactive positioning and monitoring method based on cordless communication network, utilize this method, can significantly enlarge easily and effectively locating and monitoring system working range, reduce communications expense, improve real time of data transmission and reliability, allow locating and monitoring and application mode more flexibly, the scope of application is wider.This method also can be used for navigation system or supervisory control system separately.
Another object of the present invention provides a kind of interactive locating and monitoring system based on cordless communication network, utilize this system, can be by mobile phone, the Internet easily and effectively to mobile object, the object that do not need maybe can not connect up positions and monitors, this system's up-to-dateness height, applied range, networking are reliable rapidly, system's construction and operation expense communication cost low, that be used for remote monitoring are low, the QoS that can guarantee service quality simultaneously can form industrialization and can obtain huge social benefit and economic benefit.This system can use its positioning function or monitoring function separately.
One, to achieve these goals, it is a kind of interactive positioning and monitoring method based on cordless communication network that the present invention solves the technical method that its technical problem adopts, and comprises following feature, step and submethod:
1.1 monitor terminal communicates to connect the communication mode of taking
In the present supervisory control system, the radio communication of the monitor terminal of monitored object side and monitor supervision platform side is connected and is based on mostly that mobile communications network GSM or CDMA mode realize, reason be its cost performance height, need not from establishing network, cover wide, and most mode that adopts GPRS (General Packet Radio Service) or SMS (Short Message Service).Method provided by the invention then is that the monitor terminal of the monitored object side that realizes with USSD (service of unstructured supplementary service data non-structural supplementary data) mode is connected with the radio communication of monitor supervision platform side.
1.2 the initiator that USSD communicates to connect
The initiation of USSD is normally on user's mobile phone (wireless communication terminal), the user uses mobile phone dialing USSD Number for access, corresponding information is replied again according to the input of user on mobile phone by system, and this interactively " session " process is initiated at user side (supervision subjects side).And method provided by the invention is to allow the monitor terminal of monitored object side directly initiate the USSD connection to the monitor supervision platform side, thereby sets up connection-oriented monitor message transmission channel.
This method need (must be supported the USSD function at integrated at least one mobile module of monitor terminal, preferably adopt technical grade product), obtain the USSD Number for access that is exclusively used in monitoring (for example * 109*2#) of at least one then from wireless communication network operators, and the USSD Number for access that obtains is set in advance in the dial-up circuit of monitor terminal.
1.3 USSD connects the triggering method of initiating
Because the connection of USSD can be online constantly unlike GPRS, the USSD that is initiated by the monitored object side connects and must trigger by user's (monitoring side) needs, the monitor terminal that promptly triggers the monitored object side is to platform dial (USSD Number for access), communicate to connect thereby set up USSD, utilize this channel can carry out the transmission of remote signalling and monitored instruction.
Consider the convenience of use and the cost of triggering, two kinds of triggering modes that the present invention recommends to adopt are that ring triggering or note trigger, and preferentially adopt the ring triggering mode.In principle, so long as the signaling system net of Virtual network operator, the unit in SGW (Signaling Gateway) transition network can both trigger the initiation that USSD connects by this dual mode.
1.3.1 user (monitoring side) directly triggers (being fit to point-to-point monitoring)
1.3.1.1 user (monitoring side) makes the receiving circuit of monitor terminal begin ring directly to the monitor terminal call of monitored object side or send short messages, and judges the identity and the authentication of monitoring side simultaneously according to calling number.
1.3.1.2 judge present connection status, and handle accordingly.If USSD is communicated with, but then phone or the present connection status of short message prompt user; Do not set up if USSD connects as yet, then hang up the incoming call ring immediately, monitor terminal is dialed the USSD Number for access simultaneously, establishes a communications link.
1.3.2 user (monitoring side) triggers (being fit to the monitoring of point-to-multipoint) indirectly by the monitor supervision platform side
1.3.2.1 the user after the authentication assigns the monitoring request for the monitor supervision platform side by the Internet (comprising wireless modes such as GPRS, WLAN), monitoring server triggers monitor terminal by the call or the mode of sending short messages again and dials the USSD Number for access, initiates communicating to connect of supervisory control system.
1.3.2.2 the user makes a phone call or sends short messages to the monitor supervision platform side, monitor supervision platform is judged the identity and the authentication of monitoring side according to calling number.Descending to the monitor terminal call or send short messages by call platform (subscriber exchange) or SMS platform then, dial the USSD Number for access to trigger monitor terminal, initiate communicating to connect of supervisory control system.
1.3.2.3 the user dials the USSD Number for access, initiate the monitoring request to the monitor supervision platform side, monitor supervision platform is judged the identity and the authentication of monitoring side according to calling number, descending to the monitor terminal call or send short messages by call platform (subscriber exchange) or SMS platform then, dial the USSD Number for access to trigger monitor terminal, initiate communicating to connect of supervisory control system.If access-in resource is limited, the USSD Number for access that the user dials can consistent with the USSD Number for access that monitor terminal is dialed (for example shared * 109*2#).In this case, must distinguish corresponding user instruction and monitored instruction are set, and user monitoring flow process and monitoring communications flow process, the monitored instruction that the user instruction of palpus assurance user input and the monitor terminal of monitored object side send can not be identical, conflicts in order to avoid produce.
1.4 USSD monitoring communications method of attachment
In order to make good use of the USSD passage comprehensively, efficiently, use this method should understand the relevant parameter of USSD platform before to wireless carriers, comprise response time, time-out time, byte limit, information format.In this regular scope, use following method provided by the invention.
1.4.1 because USSD adopts is communication mode mutual, compartment, system must receive that message just can provide response, promptly USSD upstream data and downlink data be one to one, timesharing sends.The inventive method is divided into two time slots, i.e. ascending time slot and descending time slot with a mutual cycle.The USSD mode all has clear and definite requirement (normally 16 to 97 about byte) to the data volume of each communication, thus at each monitor terminal when platform sends information, monitor terminal must carry out flow control.
At first define Several Parameters: the maximum fault information Du (byte) of the each up transmission of USSD, the maximum fault information Dd (byte) of the each descending transmission of USSD, terminal is dialled the USSD Number for access and is provided the time T b (second) that responds between the foundation communication to system, terminal produces the numeric code rate Fu (byte per second) of upstream data, the time-out time To of USSD system, system produces the numeric code rate Fd (byte per second) of downlink data, the actual bandwidth Bu (byte per second) that USSD is up, the actual bandwidth Bd (byte per second) that USSD is descending.
In ascending time slot, the time T u (second) of up transmission Du receives that from terminal system message is to the time T t (second) of transmission information to system's (monitor supervision platform side); In descending time slot, the time T d (second) of descending transmission Dd receives that from system's (monitor supervision platform side) terminal message is to the time T s (second) of transmission information to terminal.
USSD for singlehanded machine module connects: Bu=Du/ (Tu+Td); Bd=Dd/ (Tu+Td);
In the methods of the invention, for a mutual cycle, for making the load condition equilibrium of platform side and end side, according to the needs that network system is optimized, the system that is positioned at the upper edge sends stand-by period Ts and must set up corresponding relation with the terminal transmission stand-by period Tt that is positioned at the lower edge.An optimized proportion coefficients R is set, therefore is connected with following relation: R=Ts/Tt, establish the Tt=Δ, the Ts=R Δ is promptly arranged for a USSD.
USSD for singlehanded machine module connects, and guarantee that normal communication must meet the following conditions:
{(R+1)·Δ+Tu+Td}＜Min(Du/Fu，Dd/Fd)＜To
That is: Δ＜{ (Min (Du/Fu, Dd/Fd)-Tu-Td)/(R+i) }＜{ (To-Tu-Td)/(R+i) }
{ (To-Tu-Td)/(R+1) } is the normality item, { (Min (Du/Fu, Dd/Fd)-Tu-Td) Fu, Fd may be constants/(R+1) }, it also may be variable, in case { (Min (Du/Fu, Dd/Fd)-Tu-Td)/(R+1) } become to equaling 0, under the prerequisite that keeps communications status, Δ also must become to equaling 0.At this moment, system must trigger monitor terminal immediately and enable new mobile module, after triggering it simultaneously and dialing the time of TB at least of USSD Number for access at previous mobile module, dial the USSD Number for access and set up new USSD and communicate to connect, platform side must increase simultaneously provides one to insert thread and be this terminal use.
Connect for the USSD of two mobile modules after increasing is parallel simultaneously, the rule that proper communication must be satisfied is:
Δ＜{(Min(2Du/Fu，2Dd/Fd)-Tu-Td)/(R+1)}＜{(To-Tu-Td)/(R+1)}
·
·
·
N parallel simultaneously connection of USSD, rule is:
Δ＜{(Min(n·Du/Fu，n·Dd/Fd)-Tu-Td)/(R+1)}＜{(To-Tu-Td)/(R+1)}；
Bu＝n·Du/(Tu+Td)；Bd＝n·Dd/(Tu+Td)
After having set up new communicating to connect, the data that buffer storage produces may produce data and overflow and be made as DO.Connect by newly-established USSD, DO is passed down in the lump, and data merge when finishing in the opposite end.
Realize that above method must have synchronised clock accurately, insert specified byte in the downlink data of the inventive method system after the terminal phone module is dialed the USSD Number for access and be used for transmission, initialization system clock, the triggering signal that while makes zero as the terminal timer, insert the clock check sign indicating number then in the upstream data of monitor terminal in this reciprocal process, terminal clock and system clock are confirmed by check code all the time.
1.4.2 for the high monitoring field of security requirement, must carry out scrambled to all monitored instructions, the coding mode selection difficulty cracks, takies simultaneously the few scrambled mode of byte number.
1.4.3 for remote signalling, monitoring feedback, monitored instruction the signal of analog quantity parameter is arranged, must advanced row D/A switch, and carry out corresponding encoding and decoding by the standard rule.
1.5 localization method
The present invention relates to a kind of method for supervising of wireless, interactive, small data quantity exchange, this method will be mainly used in the monitoring to the monitored object that moves, or the monitoring of being implemented by the monitoring side that moves.In this application, in most cases be need to understand monitoring side or monitored object position, so the present invention navigation system is combined with supervisory control system, to allow supervisory control system have abundanter, practical function.According to application need, can be split as two independently selective uses of system.
In the method for supervising provided by the invention, can adopt network positions or terminal positioning mode.Network positions is meant that original position-information is the location technology that becomes at the system platform adnation, need not or very few modifications locating terminal (monitor terminal), for example Cell-ID, AOA (arrival angle) technology, TOA (time of advent) technology, TDOA (time of advent is poor) technology; The terminal positioning technology is meant that original position-information is the location technology that generates at locating terminal (monitor terminal), need revise locating terminal, for example GPS technology, AGPS technology.If the terminal positioning technology is applied to long distance control system, the original position-information that locating terminal generates must be sent to monitoring side through the telecommunication mode.
1.5.1 network positions mode
If adopt the network positions technology, then can be by the LBS platform of wireless communication network operators, according to the request of supervisory control system, in real time to the positional information of LBS platform acquisition monitoring terminal or monitoring side.Utilize this mode will locate and monitor two method examples of combination:
1.5.1.1 monitoring side is positioning and monitoring method and the step (for example access control method) that moves
At first, according to the location frequency of setting, gather personnel's mobile phone (wireless communication terminal) positional information in real time, in case personnel enter gate inhibition's scope, system initiates USSD from trend gate inhibition terminal (being monitor terminal) and communicates to connect request.Then, according to this request, gate inhibition's terminal is dialed the USSD Number for access immediately, thereby setting up USSD communicates to connect, simultaneity factor produces one at random gate inhibition that should user ID is entered or operator password, communicates to connect by USSD and sends to gate inhibition's terminal, and store; Back up in the database of gate inhibition's platform side (monitor supervision platform side) for future reference simultaneously.At last, the user dials the USSD Number for access that is exclusively used in gate control system by mobile phone (wireless communication terminal), inquire about gate inhibition's password of this user ID correspondence, and on gate inhibition's terminal, import, gate inhibition's terminal is inputed the password password corresponding with this user ID of storage before this with the user and is contrasted, the clearance if unanimity, gate inhibition's terminal are then opened the door, and make corresponding record.
In the present gate control system, majority can not solve the problem of " checking card for the people ", and phenomenons such as " being late ", " leaving early " are inquiry judging fundamentally.In addition, the majority gate access control system need the person of asking for help acquiring be used for the attachment device of identification, gate inhibition's (work attendance) card for example, in case personnel leave behind card, system will produce erroneous judgement.This method is judged personnel's time of day jointly with the gate control system combined positioning system; By the USSD monitor mode, utilize the basis for estimation of existing, the carry-on mobile phone of personnel simultaneously, allow personnel not increase new attachment device as personnel ID.
1.5.1.2 monitored object is positioning and monitoring method and the step (for example method of vehicle monitoring) that moves
For position application,, finish the position contrast on the GIS server, for system's judgement, inquiry by user's application demand is gathered vehicle monitor terminal in real time from the LBS platform positional information.Use for monitoring, set up monitor terminal communicating to connect according to aforesaid method to the monitor supervision platform side, utilize corresponding remote signalling of this Channel Transmission and remote control command then, finish corresponding monitoring, monitor terminal is divided into vehicle-mounted type and non-vehicle-mounted type: but place car interior vehicle-mounted type monitor terminal monitoring vehicle switch door and window, oil-break electricity, startup, monitoring and unmanned; Place the outer non-vehicle-mounted type monitor terminal of car can monitor other facility.
For example: according to the positioning requirements of setting, the positional information of real-time collection vehicle, when detecting vehicle and enter certain setting regions, system sends peripheral road conditions, peripheral parking stall and location-based advertising message by the USSD monitoring and controlling channels to vehicle monitor terminal, vehicle monitor terminal is converted to voice messaging with the Word message of road conditions, conveys to the car owner by receiver or loudspeaker then; When detecting vehicle and enter certain setting regions, system sends monitored instruction by the USSD monitoring and controlling channels to relevant monitor terminal, to carry out the control corresponding operation, for example: switch brake door, switch street lamp, road and bridge automatic toll.
In like manner, all be that the locating and monitoring that moves adopts said method equally for monitored object, monitoring side, prerequisite is to resolve the power issue of mobile monitoring terminal.
1.5.2 terminal positioning mode
If positioning system using terminal positioning technology, promptly original position-information generates at monitor terminal, and is gathered by location (monitoring) terminal.Best mode is: allow monitor terminal initiate to set up two USSD according to aforesaid method and communicate to connect a transmission that is used for positional information, a transmission that is used to monitor remote signalling and remote control command.If the remote signalling data volume of up (from the terminal to the platform) is little, can realize and the positional information transmission of packing simultaneously, or distribution transmission at interval, then can only communicate to connect with a USSD, monitoring location (monitoring) terminal only needs a mobile module simultaneously, has reduced hardware cost.If but only adopt a USSD passage to be used for monitoring and location simultaneously, must rationally distinguish or by the standard rule encoding control corresponding instruction, otherwise will cause the chaotic or conflict of system.
In addition, foregoing " monitoring side is positioning and monitoring method and the step that moves " reaches two kinds of method examples realization in like manner in the terminal positioning mode of " monitored object is positioning and monitoring method and the step that moves ".
Two, in order to implement said method, solve the arrowband in the remote monitoring, the technical problem of interactive communication, it is a kind of interactive locating and monitoring system based on cordless communication network that the present invention solves the technological means that its technical problem adopts, and comprises following technical measures:
System of the present invention can be split as " based on the interactive navigation system of cordless communication network " and " based on the interactive supervisory control system of cordless communication network " two independently system, can use navigation system separately, also can use supervisory control system separately.But consider that the present invention is the monitoring that realizes by cordless communication network, the most application is the supervisory control system that maybe can not connect up at not needing to connect up.And the monitor terminal in this supervisory control system, monitored side (monitoring object) or monitoring side (supervision subjects) are in and move, the for example monitoring of vehicle, boats and ships and Embedded mobile phone (wireless communication terminal) monitoring or the like, these monitoring are used and all to be based on or to need positional information, so the present invention has carried out combination with navigation system and supervisory control system according to a kind of new method.
2.1 the data communication of carrying out between the network of relation unit in the monitor supervision platform side connects, and comprises the connection of application layer.
2.1.1 monitoring server directly is connected (preferably using optical cable) with LBS (the location-based service of Location Based Services) platform, USSD (service of unstructured supplementary service data non-structural supplementary data) platform, signaling triggering platform, GIS server, WEB server, database server, application server.If system loading allows, GIS (Geographic Information System) server, application server, WEB server, database server can partly or entirely be integrated in the monitoring server.
2.1.2 triggering platform, signaling constitutes by subscriber exchange, SMS platform interface, standard communication interface circuit.The effect that signaling triggers platform is that the mode by phone ringing, downlink short message triggers and sets up monitoring and controlling channels, can adopt the mode of phone ringing, downlink short message simultaneously, carries out one main one Hot Spare that is equipped with and connects; Also can use a kind of mode wherein separately, trigger in the platform in signaling like this and can save subscriber exchange or SMS platform interface.Subscriber exchange drawn game end switch connects with trunk line, and subscriber exchange links to each other through the communication interface circuit conversion by subscribers feeder with monitoring server; SMS platform interface one end is connected with Short Message Service Gateway by the API agreement, and the other end is connected with monitoring server by standard communication interface.Need not increase, change signaling protocol newly, all adopt the current signaling system of Virtual network operator (for example signalling system No.7).If terminal quantity is few, simultaneously in order to save the initial stage construction cost, signaling triggers platform and can use phone dialer, SMS transmission module, standard communication interface circuit and queuing buffer circuit to replace constituting, and phone dialer, SMS transmission module directly are connected with monitoring server by the standard communication interface circuit.If signaling triggers platform and only uses the downlink short message mode, then this platform can save, and monitoring server directly need only be linked to each other with Short Message Service Gateway by corresponding API agreement to get final product.But consider: the needs of the communications cost of monitoring and controlling channels are set up in the issuable delay of note, non-connection-oriented characteristic and reduction, and the present invention advises separately or cooperate adopting the phone ringing triggering mode.
2.1.3 by corresponding API agreement, monitoring server directly is connected with LBS platform, USSD platform respectively, can take the direct-connected mode of IP with LBS.If the present invention need be carried other value-added functionality business, then must on (locating and monitoring) monitoring server, insert required application server by corresponding API agreement, provide interactively valued added applications service by demand to the user; Also can be on monitoring server the content of manual entry valued added applications service, carry out interactively issue by demand to the user then.
2.2 the data communication of carrying out between the associated component in the monitored object side connects.
2.2.1 basic part comprises: CPU processor, mobile module (must support USSD and GPRS function), channel trigger, various types of memory, Various types of data input/output port, transmitting-receiving control port, synchronised clock, timer, power circuit, standard traffic port constitute, and can connect by computer data bus between each circuit devcie.
2.2.2 channel trigger is formed by hanging up with dial-up circuit, ring control port, note reception and circuits for triggering, and corresponding with signaling triggering platform feature.As only needing phone or note to trigger, then can save note reception and circuits for triggering or phone and receive and hang up circuit, ring control port.
2.2.3 the expanding peripherals of monitor terminal side is made up of its specific sector application decision.For example gps system, the application of mobile POS machine, industry control application, moving game show business etc.The GPS supervisory control system must insert GPS receiver module, unidirectional remote signalling data-in port in addition; Mobile POS financial sector must insert standard P OS machine terminal in addition; In the Industry Control utilization, must insert corresponding transducer in addition and detect control circuit.
The invention has the beneficial effects as follows the interactive narrow band communication method that connects of a kind of brand-new foundation of having started, both guaranteed the QOS (service quality) that communicates to connect, allow the cost that communicates to connect become very cheap again, utilize this method to implement instant, interactively monitoring and use in extensive fields, solved in traditional monitor mode communicate to connect covering less, form is single, cost is high, no mutual many limitation.
