The terminal comprises: a power supply and a cell power supply module, a MCU module and a peripheral circuit, a DTGS-800 module and the peripheral circuit. One single chip microcomputer is used to control the DTGS-800 possessing a positioning function. Communication between the single chip microcomputer and the DTGS-800 is completed through a serial port. Working levels of the single chip microcomputer and the DTGS-800 are in working level scopes respectively. Direct interconnection can be performed. An extra level conversion circuit is not needed. The DTGS-800 uses a machine card separation technology. A connection interface which is connected with an R-UIM card is provided.
Description
Technical field:
The present invention relates to a kind ofly, relate in particular to a kind of valuables tracker terminal based on GPSOne based on GPSOne technology.
Background technology:
Consumers Council investigates and analyses the problem that current carrying trade exists, and the consumer entrusts valuables loss situation in transportation of transportation serious, causes consumer's the impaired amount of money increasing.Logistics company is usually born the task of transportation valuables, and losing of these valuables will cause their huge loss.Logistics company uses the traditional GPS location technology to follow the tracks of valuables, can reduce the probability of article lost.But under overpass or in the complicated geographical environment such as City Building is intensive, satellite-signal is lost easily; And in the transportation of whole article, valuables are placed in the metal container of lorry or leave in when indoor, utilize the GPS technology also can't obtain satellite positioning signal, are difficult to realize the effective track and localization to valuables.Simultaneously; In the traditional solution of logistics company supervisory system; GPS vehicle positioning business with GSM or CDMA mobile network short message as telecommunication media; Location and warning message are that the mode through SMS sends to the terminal user, thereby are not easy to logistics company total system is monitored in real time, inquired about and manages.
Summary of the invention:
The present invention is exactly to the problems referred to above; Provide a kind of can be in various environment in real time, location exactly; Can when thievery takes place, in time report to the police again, be convenient to the valuables tracker terminal that logistics company is monitored in real time, inquired about and manages based on GPSOne through Internet.
For reaching above purpose, the present invention adopts following technical scheme, the present invention includes power supply and powered battery module, MCU module and peripheral circuit, DTGS-800 module and peripheral circuit; Its structural feature is to control the DTGS-800 with positioning function by a slice single-chip microcomputer; Communication between them is to finish through serial ports,, the operation level of single-chip microcomputer and DTGS-800 is all within operation level scope separately; Can direct interconnection; Need not extra level-conversion circuit, DTGS-800 adopts the separation between machine and card technology, and the connecting interface with the R-UIM card is provided.
The beneficial effect of the invention:
In the locating terminal based on the GPSOne technology, the DTGS-800 module has merged multiple functions such as location, GSM and cdma network service, and integrated level and cost performance are high.System testing shows, in the intensive urban district of housing-group or indoorly realized accurate location, overcome the shortcoming of GPS technological orientation blind area.This system and device volume is little, is convenient to be installed in the article container; Locator data can send on the monitor supervision platform server of logistics company through network in time, is convenient to monitoring in real time and management; Can also when the stolen incident of article takes place, in time report to the police, be convenient to logistics company and check up on the facts, call to account, can prevent logistics company interior employee theft to a certain extent.
Description of drawings:
Fig. 1 is the overall system block diagram.
Embodiment:
The present invention includes power supply and powered battery module, MCU module and peripheral circuit, DTGS-800 module and peripheral circuit; Control the DTGS-800 with positioning function by a slice single-chip microcomputer, the communication between them is accomplished through serial ports, and the operation level of single-chip microcomputer and DTGS-800 is all within operation level scope separately; Can direct interconnection; Need not extra level-conversion circuit, DTGS-800 adopts the separation between machine and card technology, and the connecting interface with the R-UIM card is provided.
The power supply power pack comprises two parts: special powered battery and automobile power source power supply, the DTGS-800 power supply has two kinds of methods: powered battery (input of VBATT_INT pin) and externally fed (input of VEXT_DC pin).When using powered battery; Require supply voltage VBATT_INT scope to be+4.0V ± 10%; What select for use is that capacity is that 10Ah, output voltage are the lithium polymer battery of 3.7V, and the single-chip microcomputer of selection is the 3.3V power supply, and battery need add a slice LDO (low pressure difference linear voltage regulator) chip MIC5219 when single-chip microcomputer is supplied power; Its minimum differntial pressure can reach 0.3V, meets design requirement; DTGS-800 at first wants initialization system and seeks network when starting; Power consumption is higher, about 300～500mA, and the highest power consumption after settling out (under the situation of make a phone call or surf the Net, locating) is greatly about 300mA; To leave surplus during design; Therefore power supply requires can have under the situation of externally power supply (VEXT_DC) the stable DC power supply of 4.5～5V, 1A, the highlyest can not surpass 5.5V, considers that pressure reduction is bigger; And require output current greater than 1A, what select for use is that output voltage is DC-DC (Switching Power Supply) the chip LM2576-5 that 5V, output current are 3A to the maximum; Power consumption height and the low shortcoming of conversion efficiency are compared when big with LDO pressure reduction, and the DC-DC power supply chip has high conversion rate, and when pressure reduction is big, guarantee that power consumption is not too large.
The MCU peripheral circuit comprises crystal oscillating circuit, reset circuit, switch testing circuit and voltage measurement part; The switch testing circuit is used for detecting the action of travel switch; Voltage measurement partly utilizes the A/D translation function of single-chip microcomputer to measure the cell voltage of DTGS-800 power supply; When detecting the cell voltage deficiency, can send warning, need this moment power pack is transformed on the automobile power source.MCU and peripheral module circuit are as shown in Figure 4.
That DTGS-800 and interface microcontroller use is 3 line (TXD; RXD, GND) serial ports utilizes AT instruction can realize making a phone call, sending short messages and function such as location; When online and data transmission, need connect the flow control signal (like RTS, CTS and DTR etc.) of serial ports, RTS is a request to send signal; CTS is the clear to send signal, plays the Flow Control effect; DTR is the DTR signal, and the validity that data connect when being used for indicating online uses an I/O mouth of single-chip microcomputer to control in the system; When DTR=1, expression allows data to connect.This moment, single-chip microcomputer sent the online instruction to DTGS-800, and DTGS-800 just is allowed to be connected to Internet, and single-chip microcomputer can be through the server transmitting data of serial ports control DTGS-800 to assigned ip address and port numbers; Note; When module is in data connection effective status, be not respond any AT instruction, when data transmission finishes; Connect but DTR is put 0 turn-off data, this moment, DTGS-800 just can respond the AT instruction once more.
