Description

A kind of portable patient monitor device based on GPS and GSM

Technical field

The utility model relates to a kind of portable patient monitor device, relates in particular to a kind of device that obtains GPS track and localization information through GMS.

Background technology

The Along with people's growth in the living standard, the number of times that kinsfolk collective travels outdoors increases gradually, some public arenas during festivals or holidays; The crowd is centralization more, causes some areas crowded, and old man and children's the incident of wandering away is of common occurrence; Also have some physical disabilities layman to supervise to wander away when the carelessness and road can't clearly recognize the time, this not only brings very big inconvenience to the guardian, and these person's of wandering away self-care abilities are relatively poor; Some does not have normal language ability; Be easy to take place security incident, on the market do not have simple solution at present, so this is a problem demanding prompt solution.

Summary of the invention

The purpose of the utility model has overcome above-mentioned said deficiency, and providing a kind of can carry out quick track and localization to the person of wandering away, and is easy to carry the portable patient monitor device based on GPS and GSM of easy operating.

The utility model solves the technical scheme that its technical matters adopted: a kind of portable patient monitor device based on GPS and GSM; Comprise GSM long distance wireless transceiver module, single chip control module, GPS locating module and SIM module; GSM long distance wireless transceiver module, single chip control module, GPS locating module and SIM module all are positioned at the terminal; GSM long distance wireless transceiver module and GPS locating module are connected to the corresponding interface place of single chip control module; The SIM pin links to each other with the corresponding interface of GSM long distance wireless transceiver module through the SIM deck, and GSM long distance wireless transceiver module adopts TC35I.

The course of work of the utility model is: during use; The terminal is positioned on one's body the person of wandering away; At first obtain the locating information of GPS in real time, and do suitable storage, when the user wants to obtain children under guardianship's information by single chip control module; Can be through sending pre-set short message to GSM long distance wireless transceiver module; Single chip control module is handled the information that GSM long distance wireless transceiver module is received, afterwards the GPS locating information that single chip control module receives is sent back to the guardian through GSM long distance wireless transceiver module, makes the guardian can find the person of wandering away fast through locating information.

The utility model compared with prior art has following advantage: can carry out quick track and localization to the person of wandering away, be easy to carry, easy operating has guaranteed children under guardianship's safety.

Embodiment is as shown in Figure 1; Comprise GSM long distance wireless transceiver module, single chip control module, GPS locating module and SIM module; GSM long distance wireless transceiver module, single chip control module, GPS locating module and SIM module all are positioned at the terminal; GSM long distance wireless transceiver module and GPS locating module are connected to the corresponding interface place of single chip control module; The SIM pin links to each other with the corresponding interface of GSM long distance wireless transceiver module through the SIM deck, and GSM long distance wireless transceiver module adopts TC35I.

As shown in Figure 2,7 and 24 pins of GPS adopt the 3.3V power supply, select the little LM-1117 3.3 paster voltage stabilizing chips that get of volume for use.

As shown in Figure 3, gsm module TC35I is very strict to the requirement of power supply, and the operating voltage range of module is 3.3～4.8V, and recommendation is 4.2V, and when being lower than 3.3V, the TC35I module will be shut down automatically.When starting, module also need very big electric current just can start, otherwise the module cisco unity malfunction.Based on above-mentioned; LP3966-ADJ is adopted in the selection of power supply chip, and this chip can satisfy the requirement of big electric current, can reach the current peak of 3A; And can make output voltage that very big variation range arranged through regulating resistance R 13, the electric power output voltage value be selected 4.2V.

As shown in Figure 4; The TC35I module adopts external SIM, and 24～29 is the SIM pin, and last CCRST, CCIO, CCCLK, CCVCC and the CCGND of SIM directly links to each other with the end of the same name of TC35I through the SIM deck; Whether the CCIN pin of ZIF Connection Block is used for detecting SIM and inserts; If connect correctly, then the CCIN pin is exported high level, otherwise is low level.Consider the problem of interference, connect two little electric capacity at CCRST and CCVCC usually and link to each other with ground.

As shown in Figure 5, the interface voltage of single-chip microcomputer is a Transistor-Transistor Logic level, and the data port voltage of TC35I module is about 2.8V; Therefore when single-chip microcomputer and module are carried out serial communication; Can not directly link to each other, need add the port protection circuit, this partial circuit adopts the 74F07 chip to realize the conversion of port level.

As shown in Figure 6, initialization section is accomplished the initialization operation of single-chip microcomputer, and accomplishes the startup to the TC35I module, accomplishes module and signs in to the GSM network, makes it to get into holding state.Through the AT instruction gsm module is carried out the initialization setting, make it and can receive and send SMS message, control center's (mobile phone) transmitting control commands is resolved content of short message through receiving the short message subfunction, obtains gps data information, thereby realizes location fast.

During use; The terminal is positioned on one's body the person of wandering away; At first obtain the locating information of GPS in real time, and do suitable storage, when the user wants to obtain children under guardianship's information by single chip control module; Can be through sending pre-set short message to GSM long distance wireless transceiver module; Single chip control module is handled the information that GSM long distance wireless transceiver module is received, afterwards the GPS locating information that single chip control module receives is sent back to the guardian through GSM long distance wireless transceiver module, makes the guardian can find the person of wandering away fast through locating information.
