Problems solved by technology
Unable to resolve position within the recognition area
At the same time, since the 125k electromagnetic wave transmission requires a large volume of antenna to generate enough energy for tag wake-up, it is bulky and difficult to deploy. It needs to be connected to a cable when using it, and the system needs to be installed. It does not support mobile phones and tablets, and the tag requires Replacement battery
[0003] Therefore, the prior art (the scheme based on RFID technology and dual-frequency tags) has many inconveniences when running lap timing, thus a new type of portable lap running equipment system is needed

Embodiment Construction
[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0021] First, let’s explain ultra-wideband (UWB): Ultra-wideband technology is a wireless carrier communication technology. It does not use sinusoidal carrier waves, but uses nanosecond-level non-sinusoidal narrow pulses to transmit data, so the spectrum it occupies very wide.
[0022] UWB technology has the advantages of low system complexity, low power spectral density of transmitted signals, insensitivity to channel fading, low interception capability, and ...

The invention discloses a portable circle running equipment system based on a UWB technology. The system comprises a plurality of detection base stations disposed on a closed runway, a positioning device disposed on a circle running person, and a portable operation platform disposed on one side of the runway. The detection base stations comprise a first base station, a second base station, and an auxiliary base station. The first base station, the second base station and the auxiliary base station jointly form a triangular terminal point area; the positioning device is worn and mounted on the body of the circle running tester; the portable operation platform is a timing circle running system based on the UWB technology and the WiFi technology; and the system has the advantages of few system equipment, portable convenience and intelligent operation, and can be deployed without professionals, and can improve timing precision; accurate line passing time can be obtained through calculation of position information; and a wireless charging mode is adopted, the continuous and lasting use of the system is convenient.
Description
technical field [0001] The invention specifically relates to the technical field of precise positioning and wireless transmission, in particular to a portable lap running device system based on UWB technology. Background technique [0002] The existing lap timing scheme is based on RFID technology and dual-frequency tags. This scheme uses low-frequency electromagnetic waves (typically 125khz) to generate a band-shaped identification area. After entering the identification field with a tag on, it is deemed to have arrived, and communicated through RFID. The means (433m\900m\2.4G) notifies the host of the label information. The location cannot be resolved within the recognition area. At the same time, since the 125k electromagnetic wave transmission requires a large volume of antenna to generate enough energy for tag wake-up, it is bulky and difficult to deploy. It needs to be connected to a cable when using it, and the system needs to be installed. It does not support mobile...
