Abstract

The invention discloses a pedometer capable of mutual positioning. The pedometer comprises a MPU main controller, a gravity sensor, a distance and position processing module, a wireless transmit-receive unit and a display screen. The gravity sensor, the distance and position processing module, the wireless transmit-receive unit and the display screen are respectively connected to the MPU main controller. Compared with the prior art, the pedometer capable of mutual positioning has a pedometer function and a positioning function, adopts a CSS real-time positioning method, and has high positioning precision, wherein a positioning distance is 2m in a room or 1m outside a room. Compared with ZIGBEE, Wi-Fi and RFID positioned in a field intensity way, the pedometer has a strong anti-interference capacity and solves the problem that GPS cannot carry out indoor positioning.

Description

technical field [0001] The invention relates to the field of measuring the distance traveled by vehicles, people, animals or other moving solid objects on the ground, specifically a pedometer that can be positioned mutually. Background technique [0002] After searching, the applicant found that the patent document with the patent number "200710145450.X" described the principle of positioning as follows: "In the one-dimensional space under the mine, the object of positioning is a person, and every step a person takes is recorded once, and his steps The number is represented by N: under normal circumstances, the step length of a person walking is 0~255Cm, and the average step length is 60cm. Known routes, such as underground tunnels, are one-dimensional spaces, and the calculated L is actually the location of the person.” There are two obvious loopholes in the positioning method adopted by 200710145450.X: [0003] 1. The ZIGBEE positioning method is based on the signal stren...
