Embodiment 1

[0029] Embodiment 1 is a micro-power acquisition auxiliary device, such as figure 1 shown. It includes a power supply module, a delay processing module and a wake-up module; the wake-up module starts the power supply module according to the acquisition trigger signal, the power supply module sends a power supply signal to the delay processing module, and the delay processing module performs delay processing on the power supply signal and delays The processed power supply signal is converted into a data acquisition command, and the data acquisition command is sent to the data acquisition probe. After the data acquisition equipment is turned on or when it first collects data, the collected data is extremely unstable. In Embodiment 1, after receiving a signal requiring data acquisition equipment for data acquisition, that is, after the acquisition trigger signal, the data acquisition probe is not started to collect data at the first time, but the power supply module is first sta...

Embodiment 2

[0032] This embodiment 2 is based on the embodiment 1, using the micro-power consumption acquisition auxiliary device of the embodiment 1. Embodiment 2 is a micro-power acquisition method, comprising the following steps:

[0033] 1. Obtain the acquisition trigger signal;

[0034] 2. Perform delay processing on the acquisition trigger signal;

[0035] 3. When the data acquisition probe receives the acquisition trigger signal after delay processing, data acquisition is performed;

[0036] 4. Send the collected data through wireless NB. The time length for performing delay processing on the acquisition trigger signal is time length t.

[0037] The method in Embodiment 2 is applied to the pre-control of the data acquisition probe. When receiving the data acquisition command (that is, the acquisition trigger signal), the data acquisition probe will not immediately perform data acquisition, but first collect the trigger signal. After delay processing, that is, after a certain pe...

Embodiment 3

[0046] Embodiment 3 is based on Embodiment 2, and Embodiment 3 is a wireless NB digital acquisition module with low power consumption. Circuit principle such as figure 2 As shown, the processing unit can control the power management unit to independently provide power for each module as required. The processing unit is also the delay processing module.

[0047] The micro-power consumption wireless NB digital acquisition module of Embodiment 3 has a time management function. Specifically include:

[0048] Wake-up: the wake-up period is the basic time management unit of the data acquisition module in Embodiment 3. After each wake-up, according to the measured liquid level change, the wake-up time is automatically controlled (the longest time limit can be set by the user).

[0049] Alarm: Whenever the measurement data (battery voltage, liquid level, temperature, etc. optional) exceeds the alarm value set by the user, an alarm data will be sent to the platform immediately and...

Abstract

The invention discloses a micro-power-consumption acquisition auxiliary device and an acquisition method. The micro-power-consumption acquisition auxiliary device comprises a power supply module, a delay processing module and an awakening module, the awakening module starts the power supply module according to the acquisition trigger signal, the power supply module sends a power supply signal to the delay processing module, and the delay processing module carries out delay processing on the power supply signal, converts the power supply signal after delay processing into a data acquisition command and sends the data acquisition command to the data acquisition probe. After a data acquisition device is started or when the data acquisition device just starts to acquire data, the acquired data is extremely unstable. According to the invention, the stability of data acquisition is improved, unstable and unreliable acquired data is filtered, the power consumption of data acquisition equipment is reduced, and the service life of the data acquisition equipment is prolonged.

Description

technical field [0001] The invention relates to the technical field of wireless measurement and control, in particular to a micro-power consumption collection auxiliary device and a collection method. Background technique [0002] When the data acquisition equipment collects data, the data collected at the beginning is extremely unstable. Under different equipment conditions and different environments, the process of the data collected by the data acquisition equipment from unstable to stable takes a few seconds to dozens of Seconds vary. There are two main reasons for the instability of data collection. One is that due to the reasons of the data collection equipment itself, such as model differences, equipment aging, etc., the data collected at the beginning is extremely unstable. The second is due to the acquisition environment. For example, when the ultrasonic flowmeter measures the flow rate, in a scene with a long distance and a lot of interference, the data acquisiti...
