Description

technical field [0001] The invention relates to an indoor positioning and navigation system based on 485 communication and a monitoring method, in particular to monitoring indoor positioning beacons through the method. Background technique [0002] With the popularity of smart terminals, people's demand for indoor positioning is also increasing. Shopping malls, parking lots, airports, stations, scenic spots, museums, libraries and other public places need accurate indoor positioning to realize related functions based on indoor location services, so as to automatically provide users with their location, surrounding information, indoor route navigation, etc. At present, outdoor positioning systems GPS and Beidou have been widely used. Due to obstacles, positioning systems such as Beidou and GPS cannot be used normally indoors. Now indoor positioning mainly uses RFID and Bluetooth. [0003] However, the current indoor positioning system is in the initial construction stage, an...

Problems solved by technology

[0003] However, the current indoor positioning system is in the initial construction stage, and it only initially meets the needs of users for indoor positioning and navigation. For the indoor positioning and navigation system itself, there has been no effective monitoring means, and the working status of the positioning and navigation beacons cannot be known. If the indoor positioning and navigation system has been in operation for a period of time, the positioning and navigation system fails, and without effective monitoring means, the indoor positioning and navigation system will not be able to obtain timely maintenance and repairs, thereby affecting the user experience of using the indoor positioning and navigation system. It's not out of the question that it's even completely unusable, resulting in wasted investment for builders

[0004] Secondly, the indoor positioning and navigation system is used when the user is offline (the user is not connected to WIFI, 4G and other wireless networks). Currently, the existing indoor positioning and navigation system cannot obtain the user's usage information.
