A kind of remote temperature collection, control device for the cold chain transportation car
Technical field
The utility model discloses a kind of remote temperature collection, control device for the cold chain transportation car.
Background technology
In recent years, along with developing rapidly of China's economy, the raising of living standards of the people, also more and more heavier for the dependence of frozen food.Contacting food production closely, sales industry with people's daily life, the key that the Food circulation link is controlled food security and quality is temperature, and the variation direct relation of temperature the corruption of microbial growth and food.In order to keep the low-temperature condition in cold chain transportation process, the major measure of now taking is to use chill car to transport, and coordinates with some temperature control devices.It is not also very perfect supervising facility due to the cold chain of China, do not have effective supervision means to obtain at any time the temperature information of cargo hold, often occur " chain rupture " in transit or " cold junction (refrigerator is in low-temperature condition in beginning with when arriving the destination; and temperature control in transportation) " situation, cause the input of chill car to become ornaments, the quality of cold chain transportation is also made a discount widely, and a lot of perishable farm products can't guarantee fresh quality.A consequent direct result is exactly a large amount of losses of perishable farm products.According to statistics, nearly 1,200 ten thousand tons of the rotten loss of the annual fruit of China, vegetables rot to lose nearly 1.3 hundred million tons, if by 1 yuan of/kilogram calculating, the economic loss that causes is over exceeding 100 billion.If used advanced Real-time Monitor Technique in cold chain, temperature and the running status of management cold chain, can effectively avoid the generation of these situations, reduce to greatest extent the loss in transportation, guarantee the article quality, cut the waste, improve the quality of cold chain transportation, achieve high-quality Cold Chain Logistics.
Summary of the invention
The utility model is to avoid chill car " chain rupture ", " cold junction " phenomenon in transportation, and a kind of remote temperature collection, control device for the cold chain transportation car is provided.
The technical scheme that the utility model solves existing issue is: a kind of remote temperature collection, control device for the cold chain transportation car,
Comprise that one receives the monitoring center system of real-time information and comparison process information;
Also comprise the car-mounted terminal that is arranged on transport vehicle, described car-mounted terminal comprises the teledata acquisition device that connects at least one Temperature Humidity Sensor, is used for reception ﹠ disposal teledata acquisition device data and the vehicle GPS controller that is connected with monitoring center system, is connected with teledata acquisition device for the switch of control compressor and the temperature controller of cryogenic temperature, the data memory module that is provided with the wireless communication module of receiving and sending messages on described vehicle GPS controller and carries out the data storage, and the microprocessor of controlling;
Described teledata acquisition device, GPS car-mounted terminal, monitoring center system, temperature controller consist of a closed-loop system.
As further improvement, described Temperature Humidity Sensor comprises a plurality of Temperature Humidity Sensors, and described temperature controller is intelligent temperature controller.
As further improvement, described monitoring center system is made of monitoring host computer, data center server, client software, the data center server of described monitoring center system, by with the vehicle GPS controller in the GPRS module carry out network with the vehicle GPS controller and be connected, and transmit data, receive the monitoring host computer instruction to monitoring host computer by the RS232 interface, be transferred to the vehicle GPS controller by GPRS network.
the utility model is used teledata acquisition device, the GPS car-mounted terminal, wireless communication module, regulation device, monitoring center system, GPS global-positioning technology and temperature are controlled effective combination, temperature in cold chain transportation process is carried out real-time control management, compared with prior art, the utlity model has and to carry out omnidistance Real-time Collection and record to temperature, and the temperature that gathers is carried out the radio remote Distance Transmission, temperature curve, find out more intuitively the variation of temperature, when temperature anomaly in time automatic alarm and intervention control occurring, effectively avoid the generation of " cold junction " situation.

Embodiment
Referring to Fig. 1-2, the implementation case comprises a monitoring center system that receives real-time information and comparison process information, is arranged at the car-mounted terminal on transport vehicle.Car-mounted terminal comprises the teledata acquisition device that connects at least one Temperature Humidity Sensor, is used for reception ﹠ disposal teledata acquisition device data and the vehicle GPS controller that is connected with monitoring center system, is connected with teledata acquisition device for the switch of control compressor and the temperature controller of cryogenic temperature, the data memory module that is provided with the wireless communication module of receiving and sending messages on the vehicle GPS controller and carries out the data storage, and the microprocessor of controlling; Teledata acquisition device, GPS car-mounted terminal, monitoring center system, temperature controller consist of a closed-loop system.Be connected with three Temperature Humidity Sensors on Fig. 1 Tele-Acquisition device
Wherein Temperature Humidity Sensor is Study on Intelligent Sensors of Temperature, and Temperature Humidity Sensor comprises a plurality of Temperature Humidity Sensors.
Monitoring center system is made of monitoring host computer, data center server, client software, monitoring center system, by with the vehicle GPS controller in the GPRS module carry out network with the vehicle GPS controller and be connected, and transmit data, receive the monitoring host computer instruction to monitoring host computer by the RS232 interface, be transferred to the vehicle GPS controller by GPRS network.
Wherein teledata acquisition device passes through Temperature Humidity Sensor, the information datas such as the temperature in the Real-time Collection conveying carriage, humidity, and described information data is sent to the vehicle GPS controller; The vehicle GPS controller receives and processes the information data of sending, and the information exchange after processing is crossed wireless communication networks and is sent to monitoring center system far away.Monitoring center system receives real-time information, and issues regulation and control instruction to car-mounted terminal, and the vehicle GPS controller of car-mounted terminal passes to temperature controller to regulation and control instruction, and the temperature in vehicle and car, humidity etc. are controlled.
