Description
Technical field
The utility model relates to a kind of electronic equipment, is specifically related to a kind of on-site law-enforcing recorder based on intelligent mobile terminal.
Background technology
But so-called on-site law-enforcing recorder is instant recording sound, as the equipment of information; Do not have unified name academicly; People are called it " on-site law-enforcing recorder ", " police looks logical ", " on-site law-enforcing phonotape and videotape recorder ", " harmonious record ", " professional evidence-obtaining system ", " appearance of collecting evidence of enforcing the law ", " the alert photorecorder of using ", " policeman individual evidence obtaining recorder " etc. according to custom separately, and it is mainly used in the scene of law enforcement.Say that technically this equipment is exactly an audio-video tape deck, its system forms with the general large-scale supervisory control system that is made up of ' video camera-hard disk ' does not have essential difference.Their basic principle all is that the audiovisual/visual information of shooting with video-corder is recorded on the storage device, checks during for needs.The video camera that is large-scale supervisory control system outfit is more, the visiting zone is wider, and " on-site law-enforcing recorder " then more similarly is a single camera supervisory control system.See from the composition mode of the video camera of " on-site law-enforcing recorder "; Roughly can be divided into two types: a kind of video camera internally-arranged type (all-in-one) as shown in Figure 1, a kind of is video camera externally positioned type (split air conditioner) shown in Figure 2, among Fig. 1 and Fig. 2; 1 is law enforcement appearance main frame; 2 is cam lens, and 3 is screen, and 4 is keyboard; 5 is USB connector; Among Fig. 2,6 is transmission line, and 7 is mirror head outer shell.
Video camera internally-arranged type law-enforcing recorder volume is small and exquisite relatively; Can directly be worn on epaulet or the pocket and use; Because limiting it and being not easy to adopt high-grade pick-up lens, high capacity cell and large screen display of volume, weight also is difficult to be made into simultaneously portable outward appearances such as ear-hang and cap folder.Application number is that 201030675460.7,201030262521.7,200920145892.9 and 201010124018.4 one Chinese patent application just belongs to this type of technical products.Video camera externally positioned type law-enforcing recorder is independent with pick-up lens, be connected with main control system through transmission line, like this it can optional can better video camera, be more jumbo battery of host configuration and memory, so that record more data information.The main control system of therefore planting type is to be worn between waist to use, so polygamy has been put bigger display screen, so that obtain video image more clearly during playback.Application number is that 201010123765.6 one Chinese patent application and a lot of on the market at present law-enforcing recorder all belong to this type.
Fig. 3, Fig. 4 are respectively that the circuit of existing video camera internally-arranged type and video camera externally positioned type law-enforcing recorder constitutes, and except that the CPU as the control core, it mainly is made up of pick-up lens module and memory unit two large divisions.The pick-up lens module is mixed eyeglass, MIC and shell and has been formed audio-video video camera, is used to gather audio-visual data, and display screen is used for the audio-visual data data of display and operation information and playback, and keyboard is used to carry out man-machine interaction, the interface unloading data that are used for linking to each other with PC.As a kind of audio-video tape deck, obviously record is not a final purpose, and is limited because of the memory capacity of law-enforcing recorder, generally is merely able to store the audio and video files of several hrs.So in practical application, be connected with PC by the serial line interface USB through standard, the audio and video files that write down are downloaded to show among the PC and watch, edit and store.Because of the on-site law-enforcing appearance can write down the law enforcement scene, but and true reappearance scene at that time.So it is applied to departments of law enforcement agency such as public security, patrol police, traffic police, municipal administration, security, law court, industry and commerce gradually.
But two types of above-mentioned on-site law-enforcing appearance have a weak point that can not be ignored, be exactly can't field data is real-time passback make a strategic decision for commander department.The law enforcement practice shows; Only faithful reappearance law enforcement scene is far from being enough; In environment complicated and changeable, can in time let decision-making section know on-the-spot situation,, effectively protect the parties' legitimate rights and interests to be very important for properly, resolutely handling emergency case.Be the disclosed methods that can return the record audiovisual/visual information of 201020130709.0 one Chinese patent application just just like application number for this reason; It is on the basis of original circuit as shown in Figure 3, to have set up wireless launcher to form; As shown in Figure 5, its wireless launcher can be mobile communication module (GPRS, CDMA, 3G) or WIFI module.But this wireless launcher of setting up realizes that the mode of audio-visual data passback has the defective of 2 maximums:
1, adopts mobile communication module.Mobile communication module is a kind of half finished industrial product, can not use separately, generally is to be embedded in other instrument and equipments, does far distance controlled on the occasion that is difficult to reach some personnel, inconvenience is approaching or place such as the high tension electric tower and uses.Because the down work of mobile communications network that it is based on various different systems (like GSM, CDMA, WCDMA etc.), the distant control function that utilizes various services that the mobile network provides such as some normal remote control of completion such as data communication, mobile short-message to be difficult to realize.Fig. 6 is exactly the moving chip group of a standard; It has comprised the repertoire chips such as Digital Logic processing, radio frequency processing, power management and memory of mobile phone; As disposed display screen, MIC, loud speaker, the keyboard that is used for man-machine interaction, shell and auxiliary active, passive device and just constituted a complete mobile phone, see Fig. 7.And the mobile module that is used to control is that the moving chip group is produced on a circuit board; And some interface lines are drawn on a socket; In addition simplified package supplies the user that it is embedded in and uses in the controlled plant, because of this module majority is used in the Industry Control occasion and has the basic function of mobile phone; So generally be called " industrial mobile phone " or " mobile module " in the industry, see Fig. 8.Mostly " industrial mobile phone " because of its controlling object is very simple, is that number order transmits, data are sent actions such as reception though used unit is a lot, so need not the support of complicated operations system, also need not carry out various setting operation through man-machine interface.
Because of " industrial mobile phone " is industrial goods, and consumption figure can not show a candle to mobile phone, although its used unit quantity not as good as mobile phone, function far is inferior to mobile phone especially, its price also is higher than the price of normal domestic mobile phone.
So select for use mobile module to return law enforcement appearance audio-visual data, just not saying by the operation difficulty or ease of law enforcement appearance CPU control mobile module how, the suspicion of putting the cart before the horse is just arranged from cost as wireless launcher.Further see, almost be to have used a whole mobile phone only to be used for realizing transfer function, and pass into disuse other strong functions of mobile phone from the angle of resource distribution.Can find out that from shown in Figure 9 whole system has a lot of parts to repeat to be provided with, this does not meet the policy of practising strict economy, and has caused the significant wastage of material, the energy and equipment.
2, adopt the WIFI module.WIFI is a kind of interconnection technique of realizing based on the short-distance wireless communication means, and communication distance can reach hundred meters.With office building is that fixed client is different, in those public situation of assembling like on-fixed personnel such as a little airports, station, large-scale catering place, libraries, realizes that through WIFI the access of the Internet is very easily.WIFI speed is fast, and some place or even free use so receive mobile personnel's welcome very much.Present most of notebook computer and smart mobile phone are all supported the WIFI function.But compare with the mobile network, its coverage is limited really, just not saying vast rural area, even in the city except in some large-scale buildings, most areas all are the WIFI blind areas.
Since the law enfrocement official be mostly in the street, outdoor personnel compact districts such as square, fairground use the on-site law-enforcing appearance; Therefore select for use the WIFI module to return law enforcement appearance audio-visual data as wireless launcher; Be tantamount to dial mobile phone, so should technology unworkable at all in the area that does not have movable signal.
Except that above-mentioned deficiency, video camera externally positioned type law-enforcing recorder (split air conditioner) is because body volume is bigger, and except that video camera employing shoulder pendant, pocket or hat type were worn, fuselage need carry separately.And often using among the personnel of on-site law-enforcing appearance, the most general with the public security officer.But the organized equipment that the public security officer is equipped with is a lot, and is logical etc. like weapon (joining rifle, standard dagger), tool tool (baton, handcuffss, propellant, high light torch), movable police, and a part of body formula on-site law-enforcing appearance is real to belong to inconvenience as carrying simultaneously more on this basis.They more need is advantages of small volume, be easy to carry, collect the multi-functional equipment all over the body that is.
