Below in conjunction with the attached drawing in the embodiment of the present application, technical solutions in the embodiments of the present application carries out clear, complete Site preparation description, it is clear that described embodiments are only a part of embodiments of the present application, instead of all the embodiments.It is based on Embodiment in the application, it is obtained by those of ordinary skill in the art without making creative efforts every other Embodiment shall fall in the protection scope of this application.
Indoors positioning aspect, currently used technology mainly include infrared confirming orientation technology, ultrasonic wave location technology, Bluetooth location technology, radio frequency identification location technology, WLAN location technology, UWB location technology and ZigBee location technology. Above-mentioned several technologies are simply introduced first below.
Infrared ray indoor positioning technologies:
Infrared ray indoor positioning technologies utilize the good directionality of infrared ray, and emission source issues infrared-ray, infrared-ray Through ovennodulation and its own id information is had, then receives and is positioned using being mounted on indoor optical sensor. Active Badge system is exactly a kind of indoor locating system developed using infrared technology.The system disposes base indoors It stands, receives the infrared signal of objective emission, and the ID for obtaining the target is sent to location-server, the position of base station is utilized to position mesh Mark.Although infrared positioning can reach degree of precision, also there are many limitations.Infrared ray cannot pass through barrier, infrared fixed Position can only use in horizon range, when marker is placed in pocket or is blocked by other barriers such as wall, just can not Normal positioning;Since the propagation distance of infrared ray is shorter, directionality is very strong, needs to dispose very highdensity receiving sensor, at This is higher;Importantly, infrared ray is easy to be interfered by fluorescent lamp or other indoor light sources, positioning accuracy is caused to decline.
Ultrasonic wave location technology:
Ultrasonic wave positioning usually carries out ranging using the reflection of ultrasonic wave, and the position of target is then calculated by triangulation location It sets.Locating base station emits ultrasonic wave, and receives the echo of positioning target reflection, and the distance of target is calculated according to the time difference, can also To adopt method of the month list to ranging.Since the velocity of wave of ultrasonic wave is slower, ranging can achieve very high precision.But due to room Phenomena such as interior environment is usually relatively complex, and ultrasonic wave will appear reflection, interference, superposition when propagating, leads to not accurate ranging. And ultrasonic wave positioning is not suitable for the higher occasion of data communication requirements.
Bluetooth location technology:
Bluetooth is located through the signal strength detected and positions to bluetooth equipment.Bluetooth technology is that a kind of short distance is low The wireless communication technique of power consumption is perceived bluetooth equipment, can be obtained by bluetooth sensor known to the position installed in advance The approximate location of equipment.If there is multiple sensors to be detected simultaneously by bluetooth equipment, can according to each sensor position and The signal strength measured carries out range of triangle positioning.But its communication range is smaller, therefore is not suitable for fairly large room In interior positioning project.
