Wireless telemetering telecontrol system and method with ultra-low power consumption

Abstract

The invention relates to a wireless telemetering telecontrol system and method with ultra-low power consumption, aiming at achieving an ultra-low power consumption state that a controlled end is in a periodically dormant state and is used for flashly monitoring signals after wake-up. When work commands need to be sent to the controlled end, command signals are continuously sent to the controlled end by a control end in a short time; at the moment of wake-up, the controlled end only receives one-bit or plural limited-bit data signals and checks the RF characteristics thereof, particularly spread spectrum code characteristics; and only when the RF characteristics are verified, an entire data signal packet is received in a time-delay manner and then is analyzed. When the power consumption ofthe controlled end is greatly reduced, a fast wireless channel is maintained between the control end and controlled equipment, thereby opening a door for the wide application of wireless acquisition and transmission of sensor data as well as the wireless telemetering telecontrol of equipment in the IOT (Internet Of things) market. The invention also provides a long-range GPS (Global Positioning System) which is independent of a wireless mobile public network, as well as a simple and effective short-range object searching method.

Description

technical field [0001] The invention relates to wireless sensor data collection and transmission, control technology and power saving method of wireless remote control equipment, and its application in positioning search. Background technique [0002] The Internet of Things is a new information revolution far more far-reaching than the Internet. The collection and transmission of all kinds of information about things must involve control computers, remote sensors, GPS and other controlled devices, as well as low-cost and low-power wireless transmission devices connected to them. From now on, we will refer to the wireless transceiver connected to the control computer as the control terminal, and the wireless transceiver connected to the controlled device as the controlled terminal. How to make the controlled terminal quickly enter the working state when it needs to work, and not send any signal when it does not need to work, and at the same time consume very low power, is un...

Problems solved by technology

[0010] The technical problem to be solved by the present invention is to provide a simple, accurate and fast method for identifying wireless data signal packets through "DNA detection" in view of the fact that the existing general methods cannot meet the needs of the general application scenarios of the Internet of Things. It not only greatly shortens the time for the controlled terminal to monitor and identify the command signal of the controlled terminal after waking up from sleep periodically, but fundamentally solves the problem of the battery life of the controlled terminal, and the control terminal does not need to re-send work instructions to the controlled terminal. And you only need to continue to receive a complete command signal packet after the "DNA test" is over.
