Patent ID: 8648732

Claim:
A locating and tracking system, comprising: plural pressure sensing modules, each of which has a size, occupies an ADC channel, and includes: a plurality of pressure sensing units detecting a pressure source and generating a signal, wherein the plurality of pressure sensing units are in parallel connected to each other and the signal is output through the ADC channel; a data processing unit connected with the plurality of pressure sensing units, and processing the signal to generate a module information; a storage unit connected with the data processing unit, and storing the module information or a user information; a communication unit connected with the data processing unit, transmitting the module information, and receiving an outer information; and a power managing unit managing a power needed by the plurality of pressure sensing units, the data processing unit, the storage unit and the communication unit; a bottom board configured on a floor, and bearing the plurality of pressure sensing units, the data processing unit, the storage unit, the communication unit and the power managing unit; and a top board covering the plurality of pressure sensing units, the data processing unit, the storage unit, the communication unit and the power managing unit, and transferring the pressure source to the pressure sensing unit, wherein the respective sizes of the plural pressure sensing modules are classified into a first module size and a second module size different from the first module size, a part of the plural pressure sensing modules having the first module size has a first detecting resolution determined based on the first module size, and a part of the plural pressure sensing modules having the second module size has a second detecting resolution determined based on the second module size and different from the first detecting resolution.
