Embodiment 1

[0060] Embodiment 1: as figure 1 as shown,

[0061] An intelligent monitoring device for the Internet of Things of an electric vehicle, comprising an electrical signal acquisition module, a temperature acquisition module, an MCU intelligent control module including a metering sub-module, a positioning module, and an Internet of Things communication module, wherein:

[0062] The electrical signal acquisition module collects the DC circuit voltage and current of the electric vehicle battery; the connection between the electrical signal acquisition module and the metering sub-module in the MCU intelligent control module; the electrical signal acquisition module includes voltage and current acquisition and processing circuits;

[0063] The temperature acquisition module is connected with the MCU intelligent control module, and the temperature acquisition module collects the temperature signal of the battery in the electric vehicle;

[0064] The Internet of Things communication mo...

Embodiment 2

[0117] Embodiment 2: The difference from Embodiment 1 is that the metering sub-module in this embodiment still uses the RN8302 electric energy metering chip as the core, but this embodiment does not check the battery positive current, only the battery negative current acquisition and processing circuit, voltage acquisition and processing circuit Connect to any corresponding current input port and voltage input port of the RN8302 chip, such as connecting to the current input port IA and voltage input port UA respectively, the electrical signal acquisition module collects the negative current and voltage of the electric vehicle battery; the negative current acquisition and processing circuit can Directly use cost-effective high-precision manganin-copper sampling resistors, which are connected in series to the negative connection line of the electrical circuit.

[0118] Example 2 Compared with Example 1, Example 2 is an economical simplified version that no longer detects the high...

Abstract

The invention discloses an Internet of Things intelligent monitoring device for an electric vehicle. The device comprises: an electric signal acquisition module, a temperature acquisition module, an MCU intelligent control module including measurement sub-module, a positioning module, an Internet of Things communication module. The electric signal acquisition module collects voltage and current ofa battery and sends it into the measuring sub-module. The measuring sub-module converts an electric signal into a voltage and current parameter, and calculates an output power and an electric energyparameter. The temperature acquisition module collects a temperature signal and sends it to the MCU intelligent control module. The MCU intelligent control module is connected to Internet cloud platform data through the Internet of Things communication module. The MCU intelligent control module obtains positioning information by using the positioning module. The MCU intelligent control module hasa calculation processing subroutine module and an early warning logic submodule. The calculation processing subroutine module determines whether it is charging, driving, or parking state according tothe electric signal, and the early warning logic submodule alerts when there is a security risk.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to an intelligent monitoring device of the Internet of Things for electric vehicles. Background technique [0002] With the rapid development of social and economic construction and the continuous optimization of urban traffic environment, electric vehicles have gradually become the main means of transportation for urban residents with their unique advantages of convenient operation, low price, energy saving and environmental protection, and the number of electric vehicles is still growing rapidly . While electric vehicles bring convenience to everyone, they also bring fire hazards that cannot be ignored. In recent years, electric vehicle fire accidents have become more frequent. A fire occurs during the charging process of an electric vehicle. The burning of the battery produces toxic gas, which is easy to cause casualties and accidents. People will suffocate to death within 100 s...
