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.

Abstract

The invention discloses a LoRa-based intelligent cold chain vehicle system and a measurement and control method. The system comprises a measurement and control subsystem, a measurement and control main system and a remote monitoring system. The measurement and control subsystem comprises five terminal nodes, and the measurement and control main system comprises a LoRa radio frequency board, a core control board and a touch display screen. The remote monitoring system is used for displaying temperature and humidity, position information, opening and closing states, sound and light alarm information and video information in the container and outside the cold chain vehicle detected by the five terminal nodes on a mobile terminal or a PC terminal, and the information is also displayed on a touch display screen. According to the invention, the data is captured from the sensor and the state of the data is displayed on the webpage, so that a worker in a cab can observe the temperature and humidity of the cold chain vehicle, the door state and the real-time picture condition around the container door in real time. Reasonable application of resources and intelligent control of refrigeration are achieved, intelligence of the cold chain vehicle is achieved, and a system which is long in distance, long in battery life and large in capacity can be achieved.

Description

technical field [0001] The invention relates to a cold chain vehicle system in the technical field of cold chain transportation, in particular to a LoRa-based intelligent cold chain vehicle system. Background technique [0002] With the rapid development of the national economy, people continue to pursue a higher level of quality of life, and the public has higher and higher quality requirements for fresh food, medicines and other products. Cold chain transportation is an important way for the transportation and distribution of such goods, and refrigerated trucks are the main tool for short-distance transportation of perishable products in cold chain logistics, and are an indispensable part of the cold chain system. However, the uneven temperature distribution in the existing refrigerated vehicles, poor temperature control effect, and low degree of intelligence seriously limit the transportation capacity of refrigerated vehicles. [0003] In the existing technology, there a...
