Wireless transmission based data acquisition system and acquisition method with ultra-low power consumption

Abstract

The invention discloses a wireless transmission based data acquisition system and acquisition method with ultra-low power consumption. The system comprises a cloud platform, a gateway communicating with the cloud platform through a mobile network and at least one honeycomb in data communication with the gateway through a wireless module, wherein the honeycomb comprises a single-chip microcomputer, a sensor in communication connection with the single-chip microcomputer, a power management module regularly powering on the sensor and a battery electrically connected with the power management module; the single-chip microcomputer of the honeycomb comprises a data strobe module and a self-power-off module, the data strobe module receives detection data of the sensor and transmits the detection data in the range of the detection parameter threshold value to the wireless module, and the self-power-off module is used for shutting down the sensor and is in communication connection with the power management module; the gateway receives the detection data transmitted through the wireless module and sends the detection data to a cloud platform through the mobile network module. By means of the wireless transmission based data acquisition system and acquisition method, real-time on-line monitoring of the sensor in the low temperature environment for a long time is realized, and the gateway equipment is located.

Description

technical field [0001] The invention relates to the field, in particular to an ultra-low power consumption data collection system and a collection method based on wireless transmission. Background technique [0002] With the rise of the Internet of Things and the smart hardware industry, more and more products will have wireless communication capabilities. [0003] Wireless transmission acquisition equipment has been widely used in various industries. In the cold storage and cold chain industry, due to the need to operate in a low temperature environment (below 20°C) for a long time, the most commonly used solutions for data acquisition equipment are: wired access to temperature sensors and post-mortem monitoring with temperature recorders. This solution generally requires an external power supply. For the wireless connection scheme, the communication distance between the wireless acquisition gateway (or central control) and the wireless sensor (or honeycomb) is short, eve...

Problems solved by technology

[0005] The reason for this problem is that the selection of the wireless communication distance requires a long distance, and it is difficult to select the corresponding wireless module; the wireless sensor operates in a low-temperature environment for a long time, and the performance requirements for each component are strict; the wireless sensor (honeycomb) needs to be powered by a battery, and the selected It is difficult to adapt the battery; the wireless sensor (honeycomb) needs to operate with ultra-low power consumption, and the working mechanism process is relatively complicated; the wireless collection gateway (central control) is also powered by the battery when the power is off, and also requires ultra-low power consumption The process of operation and working mechanism is also very complicated; the above-mentioned reasons must be solved in a monitoring system. If any requirement is not solved, the system performance will be greatly reduced, and the function cannot meet the actual needs.
