Embodiment 1
[0035] see figure 1 , this embodiment provides a LoRa-based intelligent cold chain vehicle system, the system is the internal system and external system of the cold chain vehicle, and provides services for the cold chain control and detection of the entire vehicle. Among them, the system includes measurement and control subsystem, measurement and control main system and remote monitoring system. LoRa is a long-distance wireless transmission technology based on spread spectrum technology. In fact, it is also one of many LPWAN communication technologies. It was first adopted and promoted by the American Semtech company. This solution provides users with a simple wireless communication method that can realize long-distance and low power consumption. At present, LoRa mainly operates in the ISM frequency band, mainly including 433, 868, 915MHz and so on.
[0036] In order to consider the volume of the cold chain vehicle and the actual installation distribution of the system, the ...
Embodiment 2
[0056] This embodiment provides a LoRa-based intelligent cold chain vehicle measurement and control method, which is applied to the LoRa-based intelligent cold chain vehicle system in Embodiment 1. Wherein, the measurement and control method mainly includes the following steps.
[0057] Obtain the temperature and humidity in the container, the temperature and humidity outside the cold chain vehicle, the location information of the cold chain vehicle, the opening and closing status of the container door, and the video information around the container door.
[0058] The temperature and humidity in the container, the temperature and humidity outside the cold chain vehicle, location information, opening and closing status, sound and light alarm information and video information are displayed on the touch screen.
[0059] Display the temperature and humidity, location information, opening and closing status, sound and light alarm information and video information in the container a...
Embodiment 3
[0064] This embodiment provides a cold chain vehicle, which directly uses the LoRa-based intelligent cold chain vehicle system in Embodiment 1, which can transport various cold chain products. The cold chain vehicle can use LoRa wireless communication technology for data interaction between sensor nodes and gateways. This solution has changed the previous trade-off between transmission distance and power consumption, and provides users with a simple way to achieve long-distance, Long battery life, high-capacity systems to scale sensor networks. LoRa technology has the characteristics of long distance, low power consumption (long battery life), multi-node, and low cost. Moreover, the cold chain vehicle analyzes the real-time data and historical data of the natural temperature and humidity inside the received container and outside the vehicle, and combines the fuzzy control method to realize intelligent control of the refrigeration equipment in the container.
