Description

Mobile phone positioning system

The invention relates to a positioning system, in particular to a mobile phone positioning system.

The existing mobile phone positioning system relies on receiving GPS satellites or signals transmitted by mobile base stations for positioning.

However, the GPS satellite signal or the transmission signal of the mobile base station is susceptible to the external natural environment. For example, rain or snow weather will cause the GPS satellite signal or the mobile base station signal to become weak, resulting in poor positioning.

Moreover, the positioning method of the GPS satellite or the mobile base station can generally only locate a large area, and cannot be accurately located to the specific location of the mobile phone. For example, when a mobile phone carrier enters an office building or enters a shopping mall, since the mobile phone cannot locate its location, it is easy to cause the mobile phone carrier to lose direction or spend more time searching for a desired product selling point, thereby giving people a job. Or life is inconvenient.

In view of this, it is necessary to provide a mobile phone positioning system capable of accurately positioning a mobile phone.

A mobile phone positioning system includes a mobile phone and a positioning module coordinated with the mobile phone, the mobile phone includes a signal receiving module and a storage module, the positioning module includes a signal transmitting module, and the signal receiving module of the mobile phone Receiving a signal sent by the signal transmitting module and processing the signal to form a digit sequence in a binary form. The binary sequence of the binary form matches the positional parameters of the binary form in the storage module to achieve accurate positioning of the mobile phone.

In the mobile phone positioning system provided by the present invention, the signal transmitting module in different monitoring areas transmits a light wave signal to the signal receiving module on the mobile phone, and the mobile phone signal receiving module converts the received light wave signal into a binary digit sequence. The mobile phone positioning is realized by matching the binary sequence of the binary form with the positional parameter of the binary form of the monitoring environment stored in the mobile phone, which is not easily interfered by the external natural environment and has high positioning accuracy.

The main control module 61 controls the driving module 62 (D1, D2, D3, ... Dn) to drive the corresponding signal transmitting module 63 (S1, S2, S3, ..., Sn) to send a signal. The signal transmitting modules 63 (S1, S2, S3, ..., Sn) are respectively located in different areas (A, B, C, ..., N) of the monitoring environment to the areas (A, B, C, ..., N) ) transmitting the corresponding signal.

In this embodiment, the signal sent by the signal transmitting module 63 (S1, S2, S3, ..., Sn) is a light wave signal. Further, each of the signal transmitting modules 63 (S1, S2, S3, ..., Sn) is composed of a plurality of light emitting diodes. The light emitting diodes are respectively disposed in different areas of the monitoring environment to emit light wave signals to different areas of the monitoring environment.

The main control module 61 is configured to allocate different positions in the monitoring environment (A, B, C...N) The transmission frequency signal and the emission intensity signal of the signal transmitting module 63 (S1, S2, S3, ..., Sn). The main control module 61 transmits signals of different frequencies (f1, f2, f3, ...) set in advance to the corresponding driving modules 62 (D1, D2, D3, ... Dn). After receiving the corresponding frequency signal, the driving module 62 (D1, D2, D3, ...
