Problems solved by technology

However, the real-time data collection method based on GPRS wireless transmission mode has the following defects, which affects its large-scale application in the cold chain logistics industry:
[0003] 1. Data transmission based on GPRS wireless communication technology consumes a lot of power, periodically sending data through the mobile network base station, which consumes a lot of power for the temperature and humidity data acquisition equipment of the incubator box. Considering the manufacturing cost, as a cold chain The temperature and humidity data acquisition equipment embedded in the incubator, the most basic unit of logistics, is not suitable for large-capacity rechargeable batteries
After the battery is charged once, the device cannot support frequent or long-term continuous data uploads. Frequent battery charging also reduces the efficiency of transportation and increases battery loss.
[0004] 2. There is a fee for each data packet transmitted through GPRS communication technology, and the cumulative cost of periodically transmitting a small data packet to the server through GPRS on the basis of each insulation box device is very high
Even if the personnel in the process of logistics and transportation want to check the temperature and humidity data in the transported incubator in real time, this transmission fee cannot be avoided, and this transmission fee is not a one-time fee
[0005] 3. Each device using GPRS communication technology needs to be equipped with a SIM card. In large-scale applications, the management of the SIM card group will be more difficult. Once the management is not good, it will cause data mismatch or loss

Abstract

The invention discloses a real-time temperature and humidity data collection system and method for an in-transit incubator of cold-chain logistics. The system comprises temperature and humidity inducing and recording incubator body equipment and hand-held terminal equipment, wherein the temperature and humidity inducing and recording incubator body equipment is arranged on the incubator and is internally provided with a temperature and humidity inducing module; the temperature and humidity inducing module comprises an MCU, a temperature and humidity sensor, a first sending and receiving module, a storage module, an RTC module and an RFID label. The temperature and humidity inducing and recording incubator body equipment supports a batch-type dormant data transmission mechanism and has the data compensating transmission function, and the hand-held terminal equipment polls temperature and humidity data of the monitored incubator body equipment periodically, records the received data and uploads the data periodically in bulk or uploads the whole data to a server after transportation is finished. Based on the characteristics of low power and low cost of 433-MHz radio frequency identification half-duplex wireless communications, the system and method reduce the cost of the incubator body equipment and data transmission consumption, prolong the use time of a battery of the incubator body equipment and reduce workloads for collecting data in bulk by logistics personnel.

Description

technical field [0001] The invention relates to a temperature and humidity data acquisition system for cold chain logistics equipment, in particular to a real-time temperature and humidity data acquisition system and data acquisition method for an incubator based on RF technology with low cost, strong scalability, low power consumption, and long device battery life . Background technique [0002] The incubator is the most basic logistics unit commonly used in my country's pharmaceutical cold-chain logistics industry. Medicines that need to be transported and stored in the cold chain have very strict requirements on temperature and humidity, so the temperature and humidity monitoring records in the incubator are very important. At present, the data collection methods of incubators with temperature and humidity data collection and recording functions on the market can basically be summarized into two types, offline type and real-time type. Both methods first read the temperat...
