specific Embodiment example 2

[0025] In the reactor with gas generation, in order to avoid the explosion of the reactor, it is necessary to monitor the air pressure in the reactor in real time and continuously output the real-time air pressure. like figure 2 As shown, the working process of the pressure sensor signal acquisition chip in the reactor is as follows: turn off the variable resistor 11, the fixed resistor 12 branch 112 switch 41, open the variable resistor 11, the fixed capacitor 22 branch 111 switch 41, and allow continuous signal acquisition The branch 111 current is input to the judging module 104 inside the air pressure sensor signal acquisition chip through a pin. The judging module 104 detects whether there is an oscillation signal 102 at the port every 10 ms. As a result, three oscillating signals are detected, and the judging module 104 at this time Select the continuous signal acquisition mode, turn off the digital-to-analog conversion module 103, turn on the oscillation module 102, th...

[0027] like image 3 As shown, the working process of the PM2.5 signal acquisition chip is as follows: when the PM2.5 is excellent or good, turn off the signal acquisition input module 101, the fixed resistor 12, the variable capacitor 21, the branch 111, the switch 41, and turn on the variable resistor 11 and the fixed resistance 12 branch 112 switch 41, so that the current of the intermittent signal collection branch 112 is input to the judgment module 104 inside the PM2.5 sensor signal collection chip through a pin, and the judgment module 104 detects whether the port has oscillation every 10ms Signal. As a result, no oscillating signal is detected, then the judging module 104 selects the intermittent signal acquisition mode, closes the oscillating module 102, selects the digital-to-analog conversion module 103, and then the digital-to-analog conversion module 103 inputs the signal to the processing module 105, and the processing module recognizes the optimal signal From t...

Abstract

The invention relates to a novel structure capable of automatically recognizing continuous signals and discontinuous signals. The novel structure comprises a signal collection and input module, a judgment module, a vibration module, a digital-to-analogue conversion module and a signal processing module, wherein the signal collection and input module is located outside a sensor signal collection chip and is used for inputting signals through a pin, and other modules are located in the sensor signal collection chip. In a working process, the signal collection and input module inputs the signals into the judgment module, the judgment module detects whether a vibration signal is in a port at set intervals, if n (n is more than 2) clk signals are detected, the digital-to-analogue conversion module is automatically turned off, and the vibration module is turned on; if no vibration signal is detected at the port, the vibration module is turned off, and the digital-to-analogue conversion module is turned on so as to convert the received continuous or discontinuous signals into corresponding control signals.

Description

technical field [0001] The invention relates to a novel structure capable of automatically identifying continuous signals and discontinuous signals, and belongs to the technical field of integrated circuits. Background technique [0002] In many occasions, it is often necessary to select continuous acquisition signals or intermittent acquisition signals according to specific environmental characteristics or consumer habits. For example, when the temperature sensor signal acquisition chip is working, sometimes it only needs to collect signals for several characteristic temperature points, and sometimes it needs to carry out continuous signal acquisition for a temperature segment. For example, when the headphone sensor signal acquisition chip is working, sometimes it only needs to collect a few fixed-frequency signals, and sometimes it needs to continuously collect signals of all frequencies. For another example, when the PM2.5 sensor signal acquisition chip is working and th...
