Description
Technical field
The utility model patent relates to the novel electron tracking location system that a kind of location technology of the base station with mobile operation network combines with the less radio-frequency location technology, can be widely used in life assistance field, for the crowd of needs such as old man and children life assistance provides portable real-time tracing positioning service, have that bearing accuracy height, real-time performance are good, characteristics such as miniaturization, easy and simple to handle, with low cost, reliability height.
Background technology
Traditional satellite positioning tech (as GPS GPS etc.), when utilizing Navsat to survey and range finding, measure time delay or the phase delay that satellite-signal is propagated by the receiving equipment receiving satellite signal, thereby calculate the distance that receives between the opportunity gps satellite.The measuring distance precision is then in 30 meters, but based on the characteristics of satnav, the GPS location is not responsive especially for the location of the target on the differing heights of same place, ground, and neither be fine for the strong indoor environment usability of satellite-signal.
And mobile Operation Network base station location technology refers to obtain by specific location technology cell phone (SIM card) or terminal user's positional information (latitude and longitude coordinates), marks the technology of the object's position that is positioned at electronic chart.It utilizes the base station that the measuring and calculating distance of the distance of mobile phone is determined that customer location, measuring accuracy largely depend on the distribution of base station and the size of coverage, and the error of the location of base station is roughly about 300 meters.Compare with GPS location, what the former used satellite is satnav, locatees accurately higherly, but can't locate indoor, and relatively take.The precision of base station location technology is lower, but can be in indoor positioning.
The less radio-frequency location technology then is according to same emissive power radio frequency signal signal intensity attenuation difference when different distance is propagated, thereby calculates the signal transmitting terminal with the relative distance between the signal receiving end.The less radio-frequency location technology is less demanding and be not subject to the influence of extraneous complex conditions to environmental baseline, have easy to use, signal transmitting and receiving speed is fast, advantages such as the response real-time is good, the utmost point is applicable under indoor environment and the awkward environment of some satnaves and uses that general less radio-frequency orientation range is about circumference 1 kilometer range.
The utility model patent combines mobile Operation Network base station location technology and uses microprocessor (MCU) to carry out data and handle and analyze with the less radio-frequency location technology, thereby provide the accurate location information of signal transmitting terminal rapidly, especially for complex environment, such as complex-terrain such as between building, in the basement, floor, also can search the accurate position of target fast.
Summary of the invention
The technical matters that the utility model patent mainly solves is the portable electronic tracking location system that designs and provide high can be applicable to of a kind of bearing accuracy to live the assistance field.The utility model patent combines mobile Operation Network base station location technology on principle with less radio-frequency location skill, thereby obtain the higher novel electron tracking location system of being convenient in building, carry out track-while-scan of a kind of bearing accuracy, solved traditional location technology and can only locate the weakness that can't obtain the floor gap longitudinal position information more on the ground.
The utility model is mainly used in life assistance field, for old man and children provide portable embedded system terminal, realization personnel's location and tracking, the technical scheme that the utility model patent adopts is: the locating module of the base station of mobile Operation Network is integrated with the less radio-frequency locating module, and use microprocessor (MCU) that positioning signal and the radio frequency signal that moves the base station carried out the data processing and analyze, use display module to provide relative distance numerical value, can also use audio-frequency module output can characterize the sound signal of relative distance.
When positioning, at first send command signal (mobile phone signal) by positioning signal transmitting terminal (tracking side) and give location signal receiving end (tracked side), after positioning signal receiving end (tracked side) receives command signal, positioning signal transmitting terminal (tracking side) sends the mobile base station positioning signal, after tracking side receives location, base station answer signal, can judge tracked side's rough location information (the mistake precision is within 300 meters, as in the scope in certain bar street).Tracking side goes to after near the tracked side, start radio frequency transceiving module, positioning signal transmitting terminal (tracking side) constantly sends the command signal of having encrypted in the space towards periphery with fixing emissive power, positioning signal receiving end (tracked side) receive command signal and be correctly decoded after also towards periphery the space send the answer signal of having encrypted with fixing emissive power, positioning signal transmitting terminal (tracking side) calculates with the relative physical distance between the tracked side according to strength retrogression's situation of the answer signal that correctly receives, interval measurement that so just can the different distance different azimuth detects tracked side's azimuth information and relative distance, thereby realizes that rapid tracing and positioning is to tracked side's function.
The designed novel portable electronic tracking positioning system of the utility model patent has following characteristics:
1. integrated level height, good portability, the chip of all uses and electronic devices and components all are integrated on the circuit board, and volume is little, and is in light weight;
2. with low cost, employed all is electronic devices and components and the related chip of relatively using always, is beneficial to large-scale production;
3. employing modular design, simple in structure, be convenient to assembling and debugging;
4. the design of digitizer has guaranteed high stability.
