Embodiment
In the embodiment of the invention, a kind of novel active electric subtab equipment and system thereof are provided, in order to expand the reading/writing distance of electronic tag greatly, the feasible positional information and/or the environmental information of electron gain label in the world.
Below in conjunction with accompanying drawing the preferred embodiment of the present invention is elaborated.
As shown in Figure 1, in the embodiment of the invention, the electronic tag device systems comprises: electronic tag equipment 10 and supervision and management center platform 20, and electronic tag equipment 10 shows to the supervision and management center platform information uploading that collects through network; Wherein the present invention provides a kind of electronic tag equipment, and is as shown in Figure 2, comprises GPS collecting unit 102, main control unit 101 and communication unit 103; GPS collecting unit 102 is gathered positional information and/or the environmental information of said electronic tag equipment 10 and it is passed to main control unit 101 through receiving GPS GPS (Global Positioning System, GPS) satellite-signal;
Wherein, main control unit 101 after said electronic tag device initialize gets into dormant state, is judged the instruction type that receives from communication module, if for obtaining data command, then wake communication unit up;
Particularly; Main control unit 101; Know that through the mode of the said communication unit 103 of poll the type of communication information or the mode of interrupting judge,, then wake communication unit 103 up if said communication information is the order of obtaining information such as position and/or environment;
Supervision and management center platform 20 receives active position information and/or environmental information that said electronic tag equipment 10 sends, and shows the corresponding geographic position of electronic tag equipment and/or track and/or environment according to information.
In actual use, electronic tag equipment carries out initialization after powering on, and will get into the dormant state of low-power consumption afterwards, waits for that trigger command activates.Main control unit processor and GPS collecting unit all are in the park mode of low-power consumption.Processor is the mode that is in down trigger; Without polling mode, be exactly the communication unit module has Data Receiving (no matter be effective order, invalid command); Will the wake up process device; Carry out command recognition and handle,, then carry out the different operation process according to different commands as effective trigger command (for example obtaining data command).Wherein, each electronic tag equipment all has unique ID number, obtains the address (for example public network IP and port numbers) of carrying the supervision and management center platform in the data command, instruction type sign, communication mode information etc.Concrete for example the realization: main control unit is the special data command type of obtaining that image data is obtained in normal short message instruction or requirement through instruction type sign decision instruction type; If judge instruction type sign X for obtaining data command, just the ID number data for the electronic tag terminal collection of XX are sent to the supervision and management center Platform Server demonstration that the address is XXX through communication modes such as short message mode or GPRS.
Wherein, electronic tag equipment gets into dormant state, comprises main control unit processor and GPS collecting unit and communication unit;
Communication unit is with GSM (Global System of Mobile communication; Global system for mobile communications) module is the park mode of example; Be exactly idle pulley, for the communication mode that own GPRS own connects transmissions such as online mode and SMS short message.
The GSM communication unit exits from idle mode, and is to lean on main control unit processor (is example with MCU), and in the time of initialized, MCU (Micro Control Unit, micro-control unit) is configured to short message mode through the AT instruction with GSM; If be initialized as the normal connected mode of GPRS, just can not get into idle pulley forever, power consumption is very high.So can only select the waiting mode of note.MCU carries out a control operation again to it after resolving according to the contents processing of short message, make it be in idle pulley etc. again.
The logical relation of dormant state is:
After whole electronic tag device systems powers on; Processor initialization GSM communication unit module is in idle pulley; Press default value initialization GPS collecting unit module simultaneously, collect information such as effective positional information and/or environment after, break off the primary power of GPS collecting unit module; Only leave the ram register memory power supply (this time, GPS collecting unit module dissipation was very little) of GPS collecting unit module for; When condition satisfied (effectively obtaining data command arrives), just the mode with warm start starts GPS collecting unit module, information such as collection position information and/or environment.Wherein, after initialization was intact, MCU main control unit processor oneself also was in low-power consumption mode; When condition for example satisfies after the GSM communication module receives that short message is ordered, can withdraw from the dormant state of low-power consumption, resolve; Corresponding processing is then advanced in effectively short message order in this way.As invalid, then get into dormancy again.The process that renews so eventually.
In concrete the realization; Each unit module in the electronic tag equipment can be according to actual needs or is realized that purpose is configured and reach in the global range purpose of monitoring at any time; For example, electronic tag equipment adopts high sensitivity, and the GPS chip of low-power consumption is as the information acquisition end; Intermediate processor has adopted the series monolithic of super low-power consumption; Electronic tag equipment and Surveillance center's platform transmit interface alternately can adopt the low-power consumption gsm module, follows the tracks of through the location round-the-clock, high-precision, globalization of GPS, can locate factually by the precision of object carrier, dimension and height and speed.Through the GSM network, can make electronic tag equipment and cloud handle the supervision and management center platform in the whole world at any time and carry out real-time, interactive.User or keeper; Can be through the friendly interface of monitor supervision platform, check electronic tag by more specific location information and/or relevant environmental informations such as temperature, humidity, wind direction, illumination, sound or image such as the actual motion track of object carrier (human or animal and various article), the longitude and latitude width of cloth, avenues; Can find out that the positional information that is shown comprises geographic position and motion track information such as the longitude and latitude width of cloth, avenue; In addition, environmental information can realize that for example the acquisition of temperature can be gathered related data through temperature sensor through all kinds of relevant sensors in concrete the realization, and the acquisition of sound can be gathered or the like through sound transducer.
Further; Main control unit 101; When the electronic tag device initialize gets into dormant state; Through configuration-direct the communication mode of communication unit is set, and controls feed circuit and cut off the supply of GPS collecting unit primary power, only the basic memory electric weight of ram register of GPS collecting unit is given in configuration.
Wherein, the communication mode of communication unit has multiple, for example can be short message mode or GPRS pattern;
Further; Main control unit 101 is being judged the instruction that receives for after obtaining data command when main control unit, before giving the supervision and management center platform of appointment with said information uploading; Main control unit control feed circuit are connected the primary power of GPS collecting unit and are supplied with, and activate the GPS collecting unit.
Further, said GPS collecting unit 102 also is connected with the gps antenna 106 that obtains gps satellite signal, and this gps antenna 106 comprises inner low noise signal amplifier 1061 and outside low noise signal amplifier 1062; Electronic tag equipment is given tacit consent to the inner low noise signal amplifier of unlatching when initialization, it is good only to work as the external signal insufficient strength, when antenna damping is big, just starts outside low noise signal amplifier; When external signal intensity is abundant, close outside low noise signal amplifier, to reduce power consumption, so just can on signal intensity and power consumption, do a balance.In the concrete implementation procedure, can confirm that startup still closes outside low noise signal amplifier through the threshold value of setting signal intensity; Promptly when external signal intensity is lower than setting threshold, then start outside low noise signal amplifier simultaneously; When external signal intensity during, then close outside low noise signal amplifier more than or equal to setting threshold.
Further, the GPS collecting unit receives gps satellite signal and is translated into standard N MEA form, passs main control unit through the UART oral instructions.Particularly; For example; The GPS collecting unit receives gps satellite signal and is translated into standard N MEA (National Marine Electronics Association; U.S. navigation association) form, and pass through UART (Universal Asynchronous Receiver/Transmitter, universal asynchronous reception/dispensing device) oral instructions and pass control module MCU.Main control unit is the short message information of poll GSM (Global System of Mobile communication, global system for mobile communications) module with low power always.Effectively order short message in this way, then resolve, and carry out relevant act of execution.As for obtaining position command; Then wake gsm module up; Pass through gsm module; With short message or GPRS modes such as (General Packet Radio Service, GPRSs), the monitor supervision platform server of passing to appointment from the active position information and/or the environmental information of the acquisition of GPS module.
Further, communication unit is passed to said active position information and/or environmental information through the sensing network of wireless network, internet or tissue the supervision and management center platform of appointment.
Particularly; For example adopt the cordless communication network of telecom operators and the sensing network of self-organization; Characteristics are little, the low-power consumption of volume, and electric energy automatic regeneration, vibration resistance and water-proof function preferably provide the location-based service of the various article in the global range; Remedy the field simultaneously, i.e. application scenarioss such as asset location tracking under unattended operation environment's situation.
Further, electronic tag equipment is passed to active position information and/or environmental information the supervision and management center platform of appointment through active or passive mode; Electronic tag equipment initiatively reports Surveillance center's platform to the data that collect particularly, with the information such as position, trace information and environment that show the electronic chart that it is corresponding, also can support the inquiry of passive mode and reports.
Electronic tag equipment is passed to positional information that collects and/or environmental information data the said supervision and management center platform of appointment through mode initiatively; Trigger said electronic tag equipment and initiatively active position information and/or environmental information are uploaded to the supervision and management center platform through timer is set; Timer is set can make main control unit give server in the data that satisfy triggering active upload collection under the condition in the time interval through in obtaining data command, carrying the time interval in practical implementation; But method is not limited thereto, and also can trigger initiatively reported data through other conditions.
Further; I/O detection trigger hardware unit class alarm units such as warning button, button or touch-screen can also be set in the electronic tag device external; Make the input and output I/O pin of main control unit connect alarm unit; When said alarm unit was triggered, active position information that main control unit will obtain the GPS collecting unit through communication unit and/or environmental information were uploaded to the supervision and management center platform bound with alarm unit to show the corresponding geographic position of said electronic tag equipment and/or track and/or environment according to said information; Can realize an one-key emergent warning function like this, concrete example is pinned this button as linking to each other with this I/O pin through button of design when one, will report the information of being scheduled to modes such as note or voice our supervision and management center platform.
Further, as shown in Figure 3, electronic tag equipment also comprise be connected with main control unit and for its power supply discharge and recharge intelligent balance circuit 104, this circuit comprises high performance lithium battery 1041 and solar panel 1042.
Particularly, because the bottleneck of current techniques and technology, though conventional accumulators is can capacity big, factors such as the density of its chemical constitution cause it to be not suitable for doing the power supply of mobile device.Therefore, in this filling apparatus discharge intelligent balance circuit, adopting lithium battery, the super capacitance cell of novel process is the electronic tag power devices through the power devices way circuit.Its principal feature comprises: charging rate is fast, charges can reach more than 95% of its rated capacity in 10 seconds～10 minutes; It is long to recycle the life-span, and degree of depth charge and discharge cycles access times can reach 1 ~ 500,000 time.
In addition; On equipment power dissipation and equipment performance; Done the intelligent logical processing, particularly, lithium battery is that labeling apparatus is communicated by letter with the supervision and management center platform and main control unit is reserved basic charge value; When detecting the total electric weight of battery and be lower than said value, main control unit makes other module dormancy of said electronic tag equipment or is in off-position.
Because traditional RDID electronic tag is to produce and keep circuit or the electronic label chip work required voltage that reader obtains information through radio frequency electromagnetic; Make no reader and no battery operated electronic tag can't active or passive type transmit information; The Traditional passive electronic tag is only applicable to information the obtaining with passive mode within 50 centimetres; The working power of active electronic label is supplied with by internal cell fully; The energy supply of tag battery simultaneously also partly converts electronic tag and the required RF energy of reader communication into, maximum 1 year of battery life, and read/write distance is about 100 meters to 1500 meters.
Therefore, in the present embodiment, further; Electronic tag equipment also comprises solar panel 1042; While also on equipment power dissipation and equipment performance, has been done the intelligent logical processing, particularly; Communicate by letter with the supervision and management center platform and during the needed basic charge value of main control unit, the power supply of said electronic tag equipment will replace lithium battery to supply with through the main circuit of supplying power by solar panel much larger than electronic tag equipment when detecting said battery electric quantity.
In the foregoing description, detection can be to detect realization through hardware circuit perhaps to realize through software module control, further, discharges and recharges the balancing circuitry detection through hardware and is embodied as good; In the wilderness, under the unattended environment, it is a very fine hope that the self-regeneration of power supply upgrades.Under hardware detecting circuit and intelligent processor Comprehensive Control, can reach the self of energy well, make consumption and renewal reach balance.
Further, electronic tag equipment, when said electric circuit inspection when the total electric weight of said battery is lower than the minimum value of basic charge value, said electronic tag equipment gets into dormant state; When through for example discharging and recharging this hardware circuit of balancing circuitry when detecting said battery electric quantity greater than the maximal value of said basic charge value; During the minimum value of the basic electric weight that promptly needs much larger than the electronic tag equipment work, the power supply of said electronic tag equipment will replace said lithium battery to supply with by solar panel;
