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 ...
