Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention uses a wireless communication with a plurality of base stations, and includes a pedestrian's portable telephone with a moving distance and the number of steps as required without using a pedometer. The present invention relates to a communication system for transmitting walking data.

[0002]

2. Description of the Related Art Conventionally, navigation devices used for various moving objects such as automobiles, aircraft, ships, etc., detect the current position using a GPS (Global Positioning System) satellite. This navigation device has a position detection accuracy of 5 to 10 m, and cannot be used for a pedestrian such as a visually impaired person.

As a prior art for solving this problem, according to the description of Japanese Patent Application Laid-Open No. Hei 10-318777, an initial position of a pedestrian is measured based on position information received from a GPS satellite, and the pedestrian is mounted on the pedestrian. A navigation device has been proposed that can measure a pedestrian's current position by using a magnetic compass, a pedometer, and a gyro sensor to measure the position of the pedestrian after movement, and add the position after movement to the initial position. .

According to the description of Japanese Patent Application Laid-Open No. 6-3433, a mobile station measures its own position based on position information received from a GPS satellite, and together with the measured value, the number of the GPS satellite used for the measurement. To the base station, the base station measures at least one GPS satellite for the number using the same combination of GPS satellites, and checks the measurement error of the mobile station from the absolute position of the base station. There has been proposed a mobile station management system using GPS that corrects a measurement error of the mobile station so that an accurate position of the mobile station can be known.

[0005]

However, if the navigation device described in JP-A-10-318777 or the mobile station management system described in JP-A-6-3433 is used, an accurate position after movement can be obtained. Although it can be known, for example, multifunctional technology such as a pedometer function is not described. In the navigation device described in Japanese Patent Application Laid-Open No. Hei 10-318777, a pedometer is separately attached to a pedestrian as a detecting means for detecting the number of steps, and the moving distance is calculated from the detected number of steps.

On the other hand, when the number of steps is counted using a conventional pedometer of a mechanical display or an electronic display, although the stride when walking and the stride when running are different, they are counted as the same one step. Also, even when sitting on a chair, the waist on the waist is counted as one step, so that there is a problem that the moving distance cannot be accurately measured from the result of the step count measurement by the pedometer.

In recent years, with the development of mobile communication technology, for example, mobile telephone systems such as an automobile telephone system, a PHS (Personal Handy Horn System) and a cellular system have been widely used. Although it is possible to know the current position using a mobile phone that communicates via a number of base stations, no method has been proposed for providing accurate walking distance or walking data on the number of steps.

The present invention has been made in view of the above circumstances. For example, a plurality of base stations detect the position of a mobile phone at predetermined time intervals only by inputting a walking data request from a user's mobile phone. Then, the pedometer is mounted by calculating the exact moving distance from the position information of the mobile phone and the map information around each base station, and obtaining the exact number of steps from the preset average step length of the user. Without having to
Provided is a communication system capable of transmitting walking data including an accurate moving distance and the number of steps from a base station to a user's mobile phone as needed.

[0009]

A calculating unit that calculates the moving distance of the mobile phone from the obtained map information and calculates the number of steps from the preset average step length of the user; And a transmission unit for transmitting to the section, the display section of the portable telephone is a communication system and displaying the walking data transmitted from the base station.

According to the present invention, simply by inputting a walking data request from a user's mobile phone, a plurality of base stations detect the location of the mobile phone at predetermined time intervals, and obtain the location information of the mobile phone and the vicinity of each base station. It is configured to obtain an accurate moving distance from the map information of the user, and to obtain an accurate number of steps from a predetermined average step length of the user. Can transmit the walking data indicating the exact moving distance and the number of steps to the user's mobile phone.

When the receiving section of the base station receives a radio wave of communication information including a request for walking data from the communication section of the mobile phone, the position detecting section detects the position of the target mobile phone via the transmitting section. A request signal requesting transmission of a radio wave for performing the transmission at predetermined time intervals may be transmitted to the target mobile phone. According to this configuration, the position of the target mobile phone can be detected at predetermined intervals by radio waves transmitted from the target mobile phone at predetermined intervals.

The calculating unit of each base station plots the position of the target mobile phone detected by each position detecting unit on a map around the base station at predetermined time intervals, and based on the plotted moving direction and road distance. To calculate the moving distance of the mobile phone, and calculate the number of steps the pedestrian has moved from the calculated moving distance and the preset average step length of the user. According to this configuration, it is possible to accurately calculate the moving distance and the number of steps of the pedestrian by plotting the position of the target mobile phone at predetermined time intervals on a map around the base station stored in the map information storage unit. it can.

When the target mobile phone moves from the communication area of the base station for which the walking data is calculated to the communication area of the adjacent base station, the base station for which the walking data of the target mobile phone is currently calculated. Calculating unit transfers the calculated walking data to the receiving unit of the adjacent base station via the transmitting unit, and the calculating unit of the adjacent base station calculates the transferred walking data of the mobile phone that has moved in its own base station. It may be configured to calculate and integrate walking data. According to this configuration, even if the user moves across each base station, the walking data calculated by the calculation unit of each base station can be integrated.

[0014] The communication information may include a telephone number for connecting the mobile phone to a base station. According to this configuration, each base station can specify a target mobile phone.
