High-precision temperature sensor supporting NB-IoT

Abstract

The invention provides a high-precision temperature sensor supporting NB-IoT and relates to a high-resolution, high-precision, high-stability and low-power consumption temperature sensor which can beapplied in industrial and scientific research environments and is convenient for mass interconnection, and long-distance signal transmission and sharing. The high-precision temperature sensor comprises a quartz crystal probe (1), a satellite navigation system antenna (2), a satellite navigation system module (3), an ASIC (4), an NB-IoT chip (5), an NB-IoT antenna (6), a lithium titanate rechargeable battery (7), an ABS engineering plastic case and a silicone rubber waterproof cover; the high-precision temperature sensor can work in the environment of from minus 50 DEG C to 60 DEG C above freezing, achieve the protection grade IP67, completely prevent dust from entering and withstand water in a short time (1m); the power consumption is low, and the two lithium titanate rechargeable batteries can work for 4 years; and the high-precision temperature sensor can shares with other users, control centers and display centers of NB-IoT via an NB-IoT base station and a cloud database, is high-resolution, high-precision, high-stability and low-power consumption, supports the Internet of Things, and is convenient for mass interconnection and long-distance transmission of temperature signals.

Description

(1) Technical field: [0001] The high-precision temperature sensor supporting NB-IoT of the present invention relates to a high-resolution, high-precision, high-stability, low-power consumption that can be applied in industrial and scientific research environments, supports the Internet of Things, facilitates massive interconnection, and long-distance transmission , A temperature sensor that shares a signal. (two) background technology: [0002] The International Practical Temperature Scale is based on specified values ​​of temperature at some reproducible equilibrium states (defining fixed points), and standard interpolating instruments graduated at these fixed points of the IPT. In 1968, the international practical temperature scale was divided into three temperature zones, and the temperature values ​​in these temperature zones were defined by standard platinum resistance thermometers, standard platinum-rhodium (10%) platinum thermocouples, and Planck's radiation law.
