Embodiment Construction

[0030] figure 1 A schematic diagram of a mobile phone indoor positioning terminal device based on Bluetooth technology is shown according to a specific embodiment of the present invention. specifically, figure 1 The bluetooth module 1, radio frequency antenna 2, crystal oscillator 3, memory chip 4, TTL to RS232 module 5, 5V to 3.3V adjustable voltage module 6, and lithium battery 7 form a low-power Bluetooth mobile phone indoor positioning terminal device. Usually the RF antenna 2 is an external independent hard PCB antenna, and the signal stability is affected by the tightness of the connection interface. In this module, the antenna is directly arranged on the printed circuit board together with the Bluetooth chip, which not only ensures good receiving performance, but also reduces the cost while saving implementation space.

[0031] in such as figure 1 In the shown embodiment, the Bluetooth module 1 is connected with the TTL-to-RS232 module 5, and the TTL-to-RS232 module ...

Abstract

The invention provides a mobile phone indoor positioning terminal device based on the Bluetooth technology. The mobile phone indoor positioning terminal device is characterized in that the mobile phone indoor positioning terminal device comprises a Bluetooth module 1, a radio-frequency antenna 2, a crystal oscillator 3, a power supply module, and a TTL-to-RS232 conversion module 5, wherein the radio-frequency antenna 2, the crystal oscillator 3 and the power supply module are connected with the Bluetooth module 1 separately, the power supply module comprises a variable resistor module, and the output power of the mobile phone indoor positioning terminal device can be adjusted by adjusting the output value of the variable resistor module. By applying the terminal device, the low-cost mobile phone indoor positioning and services can be realized, and the disadvantages of GPS positioning can be overcome.

Description

technical field [0001] The present invention relates to a communication device, especially a communication device used for positioning, in particular to a terminal device based on bluetooth technology, especially a mobile phone indoor positioning terminal device based on bluetooth technology. Background technique [0002] The positioning mobile phone can be provided to special needs people in distress with one-click alarm for help, 110, 120 ambulance to quickly determine the target location, parents to query the location of the elderly and children when they go out, and alarm positioning mobile phone for safety monitoring. It can also get alarm information from the positioning mobile phone. It is a "portable nanny" for personal security and family care. It is suitable for people who need to call the police for help in case of robbery, trapped, lost, lost, sudden acute disease (heart, high blood pressure), possible disaster, children, the elderly, mentally handicapped and oth...
