Problems solved by technology

[0003] However, most of the current collectors are powered by mains electricity, and cannot use natural energy in the outdoor environment to generate electricity for their own collection work. Therefore, it is very necessary to provide an outdoor collector that can be self-powered to comply with the energy conservation and environmental protection advocated by our country.

Embodiment 1

[0019] A self-powered temperature collector of this embodiment, such as figure 1 Shown: a self-powered temperature collector, including a power supply battery, a solar panel, an energy harvester, a thermistor, and an AD converter; the power supply battery and the solar panel are electrically connected to the energy collector respectively; the The thermistor is electrically connected to the energy harvester; the AD converter is electrically connected to the thermistor;

[0020] Such as figure 2 As shown: the energy harvester includes a chip U1, a first node, a second node, a third node, a fourth node, a capacitor C1, a capacitor C2, a capacitor C3, a capacitor C4, and a capacitor C5; the first nodes are respectively connected to The positive pole of the solar panel, the second node, and the capacitor C1, and the capacitor C1 is connected to the third node; the second node is respectively connected to the VIN1 interface of U1 and the capacitor C2, and the capacitor C2 is conne...

Embodiment 2

[0024] This embodiment is further optimized on the basis of Embodiment 1, and the U1 chip also has an LDO interface. By setting an LDO, it is used to set the duty cycle of the temperature sensor power supply. When the voltage reference and thermistor network are powered by this LDO. Not only does this reduce switching noise, it also allows the application to toggle the signal chain power on and off while keeping the radio module powered on all the time. Even though the radio module doesn't consume much power between transmissions, it must always be biased to keep the timers running correctly so that the entire network remains time-synchronized. The microprocessor within the radio module sequences the LDO enable pin at the appropriate time to prepare the signal chain for reading temperature data.

[0025] The chip U1 is an LTC3330 chip. All power for this application is managed by the LTC3330. The chip contains two switch-mode power supplies and a linear voltage regulator i...

Abstract

The invention discloses a self-powered temperature collector which comprises a power supply battery, a solar panel, an energy collector, a thermistor and an AD converter, wherein the power supply battery and the solar panel are electrically connected with the energy collector respectively; the thermistor is electrically connected with the energy collector; and the AD converter is electrically connected with the thermistor. Solar energy is collected and converted into electric energy for self-working, and the temperature value of the surrounding environment is accurately acquired.

Description

technical field [0001] The invention relates to the field of temperature collectors, in particular to a self-powered temperature collector. Background technique [0002] Mobile communication is moving from the connection between people to the connection between people and things and between things. The Internet of Everything is an inevitable trend. Existing intelligent collection terminals are generally installed in the outdoor environment to collect information from monitoring points in real time, and then transmit it back to the monitoring center through wireless transmission. In the monitoring center, the collected information can be directly collected for viewing, eliminating the need for The trouble of manual on-site inspection is eliminated, and the detection information is refined, human error is avoided, and detection accuracy is improved. [0003] However, most of the current collectors are powered by mains electricity, and cannot use natural energy in the outdoor ...
