Description
Technical Field
The invention relates to the technical field of technical positioning inspection, in particular to an indoor positioning intelligent inspection system and method based on Bluetooth.
Background
Micro-area addressing location is from the beginning, and basically, radio (namely RSS, received signal strength principle), infrared and ultrasonic wave are used as the implementation carriers of the location addressing scheme.
Currently, the mainstream indoor positioning technology is as follows:
(1) UWB (ultra wide band) pulse signals are analyzed by a plurality of sensors through TDOA and AOA positioning algorithms, the multi-path resolving power is strong, the precision is high, and the positioning precision can reach centimeter level. However, UWB is difficult to implement large-scale indoor coverage, and a mobile phone does not support UWB, so that the positioning cost is very high.
(2) And (3) positioning the RFID by adopting a card swiping mode, and carrying out interval positioning on the card swiping personnel or equipment according to the position of the reader. The main application is widely used in warehouse, mill, market on goods, commodity circulation location, ETC, official working attendance etc. can't fix a position in real time, and the location accuracy is low, does not have communication ability, and the interference killing feature is relatively poor.
(3) The ZigBee indoor positioning technology is characterized in that networking is formed between a plurality of blind nodes to be positioned and a reference node with a known position and a gateway, and all tiny blind nodes are coordinated and communicated with each other to realize total positioning. As a communication system with low power consumption and low cost, the signal transmission of ZigBee is greatly influenced by multipath effect and movement, and the positioning precision depends on the physical quality of a channel, the signal source density, the environment and the accuracy of an algorithm, so that the cost of positioning software is higher, and the space is greatly improved. ZigBee indoor positioning has been adopted by many large-scale factories and workshops as a personnel on duty management system.
(4) Ultrasonic positioning is performed, an application case is represented by Shopkic, an ultrasonic signal box is installed in a shop, and a microphone of a mobile phone detects sound waves, so that the positioning is realized, and the ultrasonic positioning system is mainly used for check-in of the shop. The ultrasonic wave has large attenuation in the air, is not suitable for large occasions, and is greatly influenced by multipath effect and non-line-of-sight propagation during reflection ranging, so that the investment of bottom hardware facilities needing accurate analysis and calculation is caused, and the cost is too high.
(5) Inertial navigation has poor indoor positioning effect due to uncertainty of initial attitude of the mobile phone and accuracy problems of an inertial sensor of the mobile phone. More and more people use autonomous inertial sensor positioning navigation to assist navigation at present, especially under the condition that the IOS mobile phone does not open interfaces such as RSSI and the like.
(6) LED location, the system realizes through the LED lamps and lanterns to the ceiling, and the lamps and lanterns send the scintillation signal like the Morse telegraph password, and is received and is detected by user's smart mobile phone camera again, and the positioning accuracy can be within 1 meter. The LED lamps and lanterns need be reformed transform in the LED location, increases the chip, increases the cost, and the infrared ray can only the stadia spread, and the penetrability is extremely poor also very easily receives environmental factor influences such as light, smog obvious. The positioning effect is limited. The method is suitable for accurate positioning and recording of the track of a simple object in a laboratory and positioning of the position of an indoor self-walking robot. Nevertheless, LED positioning is a very promising indoor positioning technology.
(7) Wi-Fi positioning, due to the popularity of Wi-Fi networks, has become very popular. Wi-Fi location can reach meter level location (1 ~ 10 meters), and there are two kinds Wi-Fi location technique, one kind is through the wireless signal intensity of mobile device and three wireless network access point, through the difference algorithm, carries out the triangulation location to people and vehicle relatively accurately. Another is to record the signal strength of the huge amount at a certain location point in advance and determine the location by comparing the signal strength of the newly added device to a database with huge amount data ("fingerprint" location). However, the iOS does not support Wi-Fi indoor positioning (Apple locks things at the Wi-Fi bottom layer, developers cannot know some Wi-Fi important messages), accurate positioning cannot be achieved, and response speed is low. Wi-Fi location is applicable to the location navigation to people or car, can be used to various occasions that need the location navigation such as medical institution, theme park, mill, market.
(8) The two products are mostly used for military and scientific detection at present, such as geomagnetic navigation commonly used for military underwater navigation, and computer vision navigation used for Mars vehicle navigation.
(9) Bluetooth beacon technology positioning, bluetooth positioning is based on RSSI (signal field strength indication) positioning principle. According to the different of the positioning end, the Bluetooth positioning mode is divided into network side positioning and terminal side positioning. The network side positioning system is composed of terminals (such as mobile phones and other terminals with low-power-consumption Bluetooth), Bluetooth beacon nodes, a Bluetooth gateway, a wireless local area network and a back-end data server.
As shown in fig. 1, a comparison graph of the various indoor micro-area addressing locations is shown, according to various location technologies and application scenarios, parameter indexes and advantages and disadvantages of the various technologies are as follows:
in conclusion, the various indoor micro-area addressing and positioning technologies in the prior art have poor comprehensive effect and cannot balance various parameter indexes.
