Wireless communication wake-up circuit

Abstract

The invention discloses a wireless communication wake-up circuit, which comprises a smart power source, a sensor module, a wireless transmission module, a singlechip, a wakeup unit and a timing chip. The smart power source respectively supplies power to the sensor module, the wireless transmission module, the singlechip, the wakeup unit and the timing chip. The sensor module is respectively connected to the wireless transmission module and the singlechip; the singlechip is respectively connected to the wakeup unit and the wireless transmission module; the wakeup unit is also connected to the timing chip. According to the wireless communication wake-up circuit, the wakeup unit is used to complete intermittent opening and operation of the whole system so as to overcome the problem that a complicated MAC protocol and an accurate and high-cost precision time protocol are adopted in a traditional wireless sensor network for data routing. The wireless communication wake-up circuit uses a dual power supply technology to improve the reliability of system communication, is easy to install, saves the cost, simplifies the communication protocol, reduces the nodal communication energy consumption, and extends the life cycle of the system.

Description

technical field [0001] The invention relates to a wake-up circuit, in particular to a wireless communication wake-up circuit. Background technique [0002] Information collection technology is widely used in the current society, from the most basic water level monitoring, temperature monitoring to air quality monitoring, sunspot changes, maritime search and rescue and other fields. This type of information collection system needs to measure and report water level to the information center in real time , temperature, location, video and other data for the information center to collect and process, providing accurate and scientific data for effective management, decision-making and scheduling. [0003] Traditional information collection uses wired data transmission and a single power supply for power supply. For special applications such as sea rescue, this method cannot meet the requirements of use. Therefore, only wireless transmission methods can be used for information tra...

Problems solved by technology

[0003] Traditional information collection uses wired data transmission and a single power supply for power supply. For special applications such as sea rescue, this method cannot meet the requirements of use. Therefore, only wireless transmission methods can be used for information transmission and interaction. In the working state, the power supply of the system is a key issue, especially when some information collection points used for search and rescue need to provide on-site information for their work in case of an accident, they often do not have enough power to ensure their long-term work
