Problems solved by technology

[0003] At the same time, with the rapid development of my country's economy, the construction of smart cities has also been included in the national development strategy. Meteorological data, as an indispensable data for smart cities, plays a very important role. At this stage, fixed-point construction of weather stations is generally used for weather monitoring At the same time, with the construction of smart city big data, sparsely distributed urban weather monitoring stations can no longer meet the needs of current weather monitoring, so the use of Beidou smart city vehicle-mounted weather collection and monitoring devices is also general trend
[0004] At present, there are the following problems for the vehicle-mounted weather collection and monitoring device and method: First: most of the weather data collected continuously will cause a large difference between the measured data and the actual data due to the speed of the vehicle
Second: The monitoring module continuously collects and uploads data, resulting in a large amount of data for a single vehicle
Third: The existing on-board weather module does not consider power consumption, resulting in energy waste
[0005] Currently, there are many schemes for vehicle-mounted weather monitoring, but the methods are relatively simple, the monitoring is not comprehensive enough, and the data is not accurate enough. It can only provide wrong weather information for a long time, and cannot be applied to the field of vehicle-mounted weather monitoring.

Embodiment 1

[0044] A Beidou-based vehicle-mounted weather collection and monitoring device for smart cities, including a vehicle-mounted module and a weather monitoring module; the vehicle-mounted module is installed at the front bumper of the vehicle;

[0045] Such as figure 1 As shown, the vehicle-mounted module includes a microcontroller module, a Beidou positioning module, an NB-IoT communication module, a power module, a vibration module, and a storage module;

[0046] The Beidou positioning module is used for: the vehicle uses the Beidou system for real-time fixed-point positioning and obtains positioning data;

[0047] The NB-IoT communication module is used to: upload and download positioning data (can track any data that can be placed on the device. Including vehicle position information, vehicle speed information, vehicle direction information, etc.), meteorological data; NB- The IoT communication module has a built-in SIM card of the mobile operator, which is responsible for c...

Embodiment 2

[0054] According to a kind of Beidou-based smart city vehicle-mounted weather collection and monitoring device described in embodiment 1, the difference is that:

[0055] Such as figure 2 As shown, the weather monitoring module includes a PM2.5 particle detection sensor, an air pressure sensor, a temperature sensor, and a humidity sensor;

[0056] The PM2.5 particulate matter detection sensor collects the PM2.5 concentration on the road surface, the air pressure sensor collects the road surface air pressure, the temperature sensor collects the current location temperature on the road surface, and the humidity sensor collects the current road surface humidity.

[0057] The microcontroller module, Beidou positioning module, NB-IoT communication module, power module, vibration module, and storage module are integrated into the vehicle module, and connected to the power supply line of the vehicle through the wide-voltage power management circuit of the power module. Make sure th...

Embodiment 3

[0062] The working method of any Beidou-based smart city vehicle-mounted weather collection and monitoring device described in embodiment 1 or 2, such as image 3 , Figure 4 As shown, including the following steps:

[0063] (1) When the vehicle is turned on, the vibration module collects the vibration signal generated when the vehicle is running, and sends the start signal to the microcontroller module;

[0064] (2) The microcontroller module receives the start signal and turns on the vehicle-mounted module;

[0065] (3) The microcontroller module judges the current running speed of the vehicle by connecting the wheel speed sensor of the vehicle. When the current running speed of the vehicle is greater than 30km / h, the microcontroller module continues to judge the current running speed of the vehicle in real time by connecting the wheel speed sensor of the vehicle. Otherwise, the microcontroller module records the current driving speed of the vehicle;

[0066] (4) When the...

Abstract

The invention relates to a Beidou-based smart city vehicle-mounted meteorological acquisition monitoring device and method. The Beidou-based smart city vehicle-mounted meteorological acquisition monitoring device comprises a vehicle-mounted module and a meteorological monitoring module. The vehicle-mounted module comprises a micro-controller module, a Beidou positioning module, an NB-IoT communication module, a power supply module, a vibration module and a storage module. The vehicle-mounted module is started through vibration generated when a vehicle runs and collected by the vibration module. The micro-controller module judges the current running speed by being connected with a vehicle wheel speed sensor. When the running speed is reduced to 0 km / h, the Beidou positioning module positions site information, the meteorological monitoring module monitors the meteorological data of the current positioning position and stores the collected meteorological data in the storage module, and the micro-controller module processes the meteorological data and uploads the meteorological data to a smart city server through the NB-IoT communication module. A large amount of credible and accurate meteorological data can be provided for a smart city big data platform, the construction of a smart city is promoted, the application environment urgently meets the requirements, and the market prospect is wide.
