Technical Field

[0001] This utility model relates to the field of dual-mode communication technology, and in particular to a Beidou handheld dual-mode communication device. Background Technology

[0002] Currently, railway construction and maintenance are highly mechanized, with various types of rail vehicles widely used. However, safety protection measures mainly rely on human and physical measures. Due to inaccurate positioning and poor communication, safety accidents occur frequently during railway construction and maintenance. CN208766307U discloses a handheld terminal for indoor and outdoor high-precision positioning and dual-mode communication, including a housing. A 900MHz radio antenna, a Beidou positioning antenna, and a switch are located on the top of the housing. An OLED display and a speaker are located on one side of the housing. Inside the housing is a positioning device, which includes a microcontroller, a Beidou / GPS locator, a GSM network, a radio, an inertial navigation device, and a UWB ranging device. The Beidou / GPS locator, GSM network, radio, inertial navigation device, UWB ranging device, OLED display, and speaker are all connected to the microcontroller. The radio is also connected to the 900MHz radio antenna, and the Beidou / GPS locator is also connected to the Beidou positioning antenna. Existing communication devices require users to hold the device casing in their hands for communication. However, this requires continuous hand-holding to ensure stable communication signals while walking or climbing, which not only increases hand strain but also makes the device prone to slipping and damage. Some wearable devices have a single fixed position, making it difficult to adjust the device's posture according to actual needs, which affects signal reception and ease of operation. Therefore, we propose a Beidou handheld dual-mode communication device. Utility Model Content
