Description

Pressure detecting system, module and method

Technical field

本申请涉及压力检测技术领域，特别涉及一种提高压力检测信噪比的检测系统、模组及方法。The present application relates to the field of pressure detection technology, and in particular, to a detection system, a module and a method for improving a signal to noise ratio of a pressure detection.

Background technique

参见图1，压力检测芯片由压力检测系统1和压力检测传感器2组成，压力检测传感器2有N个压力检测通道，N为自然数(C0,C1,…,CN)。每个压力检测通道负责整个压力待检平面中的某一小块区域。压力检测系统1包括开关切换模块11、采样模块12、模数转换模块13以及数字控制与处理模块14，所述开关切换模块11通过模拟开关采集各压力检测通道的压力信号，所述采样模块12对采集的压力信号进行采样，通过数模转换模块13将采样信号转换为数字信号并送给数字控制与处理模块14，数字控制与处理模块14将数据计算成压力值。Referring to Fig. 1, the pressure detecting chip is composed of a pressure detecting system 1 and a pressure detecting sensor 2, and the pressure detecting sensor 2 has N pressure detecting channels, and N is a natural number (C0, C1, ..., CN). Each pressure sensing channel is responsible for a small area of the entire pressure pending plane. The pressure detecting system 1 includes a switch switching module 11 , a sampling module 12 , an analog-to-digital conversion module 13 , and a digital control and processing module 14 . The switch switching module 11 collects pressure signals of the pressure detecting channels through an analog switch, and the sampling module 12 The acquired pressure signal is sampled, the sampled signal is converted to a digital signal by digital to analog conversion module 13 and sent to digital control and processing module 14, which calculates the data as a pressure value.

参见图2，以九通道压力检测传感器为例，每个节点对应一个关联压力检测区域，即节点0，节点1，节点2，…，节点8，(C0,C1,…,CN)。所述9个节点对应压力检测传感器2的9个压力检测通道。扫描一帧数据的时序图3中颜色相对的深色区块代表当前时刻正在采样的压力检测通道，图3中颜色相对的浅色区块代表当前时刻空闲的压力检测通道。由于信噪比是压力检测芯片的重要指标，如果要提高压力检测的信噪比，扫描一帧数据的时序参见图4。由此可知，为了提高压力检测的信噪比，增加了每个压力检测通道的采样时间，导致采样总时间也成倍地增长，这势必会很大程度上增加功耗和降低刷新率。 Referring to FIG. 2, taking a nine-channel pressure detecting sensor as an example, each node corresponds to an associated pressure detecting area, that is, node 0, node 1, node 2, ..., node 8, (C0, C1, ..., CN). The nine nodes correspond to nine pressure detecting channels of the pressure detecting sensor 2. Timing of Scanning One Frame of Data The color-dependent dark blocks in Figure 3 represent the pressure detection channels being sampled at the current time. The light-colored blocks in Figure 3 represent the pressure detection channels that are idle at the current time. Since the signal-to-noise ratio is an important indicator of the pressure detection chip, if the signal-to-noise ratio of the pressure detection is to be improved, the timing of scanning one frame of data is shown in FIG. It can be seen that in order to improve the signal-to-noise ratio of the pressure detection, the sampling time of each pressure detection channel is increased, and the total sampling time is also multiplied, which will inevitably increase power consumption and reduce the refresh rate.
