In today's affluent era, the market demand for fruits, vegetables, meat, and seafood has gradually increased with the improvement of people's living standards. When transporting from all over the country to the farmer's market, the texture is still fresh, and the demand for cold chain transport vehicles has gradually increased.
The cold chain transportation industry has gradually grown with market demand. The cold chain transportation mainly uses the cold chain transportation vehicle. The cold chain transportation vehicle is designed to effectively combine the temperature and humidity monitoring system with the vehicle. The initial temperature and humidity monitoring for cold chain transportation was only to install a temperature and humidity meter in the compartment to monitor the temperature and humidity in the compartment. When entering the rest area for parking and rest, manually check the data and record manually to ensure the qualified temperature and humidity in the compartment. .
Xinxin Wulian has designed a new wireless GPS temperature and humidity recorder based on the needs of both the transportation company and the shipper. This wireless GPS temperature and humidity recorder is only for cold chain logistics vehicles.
The wireless vehicle GPS temperature and humidity recorder has a built-in high-performance GPS module and a GPRS module, and the probe uses a high-precision temperature sensor and a humidity sensor . While monitoring the temperature and humidity environment in the cabin, the data can be sent to the cloud server for storage through the GPRS wireless communication module, and the real-time location of the vehicle can be displayed on the map through the GPS positioning function. The transportation company can log on to the cloud to view the real-time location of the vehicle, the driver's name, and the phone number; the shipper can view the vehicle temperature and humidity information, the vehicle's location, the driver's name, and the phone number on the cloud server.
The new generation of wireless car GPS temperature and humidity recorder measures temperature range of -40 ℃ ~ 100 ℃ and humidity range of 0 ~ 100% RH; measurement accuracy is: temperature ± 0.5 ℃, humidity ± 4.5% RH; resolution is 0.1; The working conditions are temperature -15 ℃ ~ 60 ℃, humidity 10% RH ~ 90% RH (non-condensing); power supply voltage DC6V ~ DC18V.
The wireless vehicle GPS temperature and humidity recorder data transmission signal has the characteristics of strong penetrability and strong anti-interference ability, accurate measurement, high transmission sensitivity, and simple installation. The vehicle temperature and humidity recorder itself can communicate with the RS-485 communication interface. The computer, sensor gateway, host computer, GPRS module, other modules and other equipment together form a temperature and humidity monitoring system . Its long-term stable work greatly improves the reliability of low-temperature logistics transportation .
