Self-propelled vehicle networking location, warning, monitoring, charging method and system
The present invention relates to a kind of self-propelled vehicle networking location, warning, the method for monitoring and the system equipment of implementing this technical scheme.
Along with popularizing of self-propelled vehiclees such as automobile, self-propelled vehicle is stolen, be robbed etc., and social security problem is more and more outstanding, with new and high technology means solve motor vehicle antitheft, anti-misfortune problem has become an invention focus.Present main technical schemes has three classes: the one, and the artificial earth satellite Positioning System (GPS).This system's accurate positioning, the networking scope is huge, and the advance of technology is the highest in all kinds of schemes.But the original intention that designs this system mainly is the location that is used for military target, or the navigator fix of aviation, navigation; Rather than be used for the anti-theft alarm of automobile, so when it is used for the motor vehicle antitheft warning, exist cost too high, deadly defect such as be difficult to popularize.Simultaneously, the antenna of vehicle-mounted emitter is longer in this technology, is difficult for hiddenly, is destroyed by the offender easily.Second class is the cell phone warning, and this type systematic has a lot of different technologies schemes, is that wireless set is installed on self-propelled vehicle basically, utilizes wirelessmobile communication system to report to the police.This class technical scheme can be finished the task of anti-theft alarm, but has a large amount of blind spots, and exists the networking expense to cross high disadvantage equally.The 3rd class is the cas system of " short wireless, long wired ", for example No. 94111523.2 disclosed schemes of Chinese invention patent.Vehicle-mounted emitter promptly is housed on self-propelled vehicle, some acception stations distribute in the networking district, acception station receives the radio signal of vehicle-mounted emitter in short range, convert wire signal again to and add the geocoding of our station, utilize the wire communication circuit to be connected, report to the police by the network system of this " short wireless, long wired " with the computing machine of monitoring center.This class scheme blind spot is less, and reliability is higher, and the cost of networking expense and vehicle-mounted emitter is all lower, is fit to China's actual conditions, is easy to promote.But the acception station in this scheme is bearing dual role: it is switching station, repeater station between wireless signal and the wire signal; It simultaneously is again the terrestrial reference station of filling geocoding.Finishing the preceding paragraph task must be that every station is provided with a wire communication circuit, so networking is subjected to the restriction of wire communication circuit when setting up an office, this restriction has restricted the scope of networking, also can cause blind spot at some places, and this also becomes the obstacle of further cost-cutting.Simultaneously, also there is a technical barrier in this scheme, and promptly improve the contradiction between accuracy of positioning and the elimination blind spot: when the emissive power of vehicle-mounted emitter was too small, the location more sparse in acception station can produce blind spot; When power is excessive, location at acception station's comparatively dense can produce " ghost image demonstration " again, the alerting signal that is vehicle-mounted emitter is received simultaneously by near several acception stations (or even the acception station near other roads), each acception station adds that all the address code of oneself is transmitted to monitoring and control centre again, cause same warning car several addresses on electronic chart, to occur and show that this phenomenon has reduced accuracy of positioning.Just require in same networking district for eliminating this phenomenon, the density degree that acception station layouts is relatively more consistent.Though this contradiction solves in actual engineering, need engineering staff's experience and a large amount of work, and address this problem on the whole, then need technical scheme is improved.
In order further to improve antitheft, the anti-method and system of robbing, paying the fees of CAS, the invention provides a new technical scheme, comprise its method and system equipment, this scheme should be under lower cost, further eliminate blind spot and enlarge monitoring range, the reliability that raising is reported to the police and the accuracy of location.New departure should not be subjected to the restriction of wired communication line when the terrestrial reference website is set, thereby helps enlarging the scope of networking, improves the countercharge ability of this system to the warning vehicle simultaneously.
The same with original cas system, vehicle-mounted emitter is housed on the self-propelled vehicle (can be established beeper receiving device and remote controller and receive head on the vehicle-mounted emitter, can launch and receive radio signals, No. 98226159.4 disclosed vehicle-mounted emitters of utility model patent for example), networking is provided with some acception stations in the district, convert the signal of vehicle-mounted emitter to wire signal, utilize the wire communication circuit alarm.Different is: the dual role of former acception station is decomposed in two kinds of mechanisms finish: the address code of warning vehicle, not to add when the forward signal by each acception station, but be provided with networked beacons station (being the terrestrial reference station) in addition, each networked beacons station emission terrestrial reference signal separately, vehicle-mounted emitter receives the terrestrial reference signal, and when the emission alerting signal, the terrestrial reference signal in location of living in is transmitted to acception station together during with warning, is transmitted to monitoring and control centre again.Because the coding difference at each networked beacons station, monitoring and control centre can be judged warning vehicular seat point in view of the above.The acception station of this moment only bears the task of forward signal, can rename as the upper layer network warning service, and its deployment site and quantity can only be considered the signal forwarding function, and the cloth dot density can reduce.In the place that does not have telephone wire, can establish gsm wireless network alarming station as a supplement, receive, transmit alerting signal with wireless mode.Optimal design of the present invention is: (even be included in beyond the networking district other crossings, distant place) is provided with login station, some critical points at the crossing of networking area edge, rolls the self-propelled vehicle in networking district away from order to login, charge or control.Signal is inquired in critical point login station emission; After the vehicle that crosses this login station receives this signal, i.e. the emission login or the signal of paying the fees are offered the login station with the coding of this car and are put on record, and monitoring and control centre can be grasped data such as the license number that rolls the monitored space vehicle away from, whereabouts, time; Relevant departments can login, charge.In networking district, some network control stations can be set, in order to control warning vehicle, make its parking, or finish multiple functions such as bringing out alert, sound and light alarm, releasing alert according to the instruction of monitoring and control centre with the remote control means.More than said warning vehicle comprise " manually repay newspaper vehicle ", promptly stolen when vehicle, when robbing, the remote annunciator that does not enter " alert status " or driver as vehicle-mounted emitter is detained on the car, driver's available phone is carried out " manually repaying " to monitoring and control centre, send the vehicle-mounted emitter warning that this car is brought out in instruction by monitoring and control centre, and notify each network control station, this car of critical point login station interception this car data data.More than said networked beacons station, upper layer network warning service, login station, critical point and network control station, it is the division on the function, actual establishing when standing, each function can intersect or repeat, be the various functions that same website can possess beaconing station, warning service, login station and control station simultaneously, one or more functions wherein also can only be set.Another optimal design is to be provided with carry-on warning receiver, the alerting signal of vehicle-mounted emitter is when offering monitoring and control centre by the network alarming station, the car owner can receive alerting signal on the warning receiver with oneself, when again alert taking place outside vehicle is in the network alarm district, the car owner also can receive alerting signal.
