Abstract

The invention relates to a force / position touch sensor detection system and method. The force / position touch sensor detection system comprises a force / position touch sensor, excitation sources, an analog switch, a signal processing circuit, an analog-digital converter and a controller; the excitation sources are electrically connected with the force / position touch sensor through the analog switch;the signal processing circuit is electrically connected with the force / position touch sensor through the analog switch; the controller is electrically connected with the analog switch and used for controlling the switching state of the analog switch and then switching connection between an excitation electrode set of the force / position touch sensor and the excitation sources and the signal processing circuit; the signal processing circuit is connected to the controller through the analog-digital converter, and further connected to the excitation sources. According to the force / position touchsensor detection system and method, by applying excitation sources to two sets of excitation electrodes in a time-sharing mode, voltage signals of pressure and position can be collected, the cost is low, and the detection period is greatly shortened; meanwhile, output signals can be effectively converted into actual stress position coordinates and pressure magnitudes.

Problems solved by technology

Although the detection accuracy of each sensing unit of the array sensor is very high, since each sensing unit is not completely continuous, there are detection blind spots, and with the increase of sensing units, there are many input and output leads, so that the detection When the system detects large areas, the amount of data to be processed is too large, which affects the real-time performance of the detection
