Description
Technical field
The present invention relates to logistics monitoring field, it is related to a kind of vehicle-mounted real-time prison of passive and wireless cold chain transportation based on Internet of Things
Control system, is particularly suitable for use in the occasion higher to transit link requirement, such as cold chain transportation car, fresh and live agricultural product, medicine etc. are transported
Defeated car.
Background technology
With the fast development and the continuous improvement of Living consumption of China's economy, the consumption idea of people is from traditional
Unification changes to modern variation, high-speeding, not only requires fresh, hygienic fresh agricultural products, safety, nutrition, but also
It is required that numerous in variety, dispatching is rapid timely.Cold Chain Logistics refer in production, processing, storage, transport, sale, until final consumption
In preceding links, perishable, fresh food is remained at into defined low temperature environment, ensures to eat with optimal logistics means
Quality, reduces a kind of logistics system of food loss, is in order to ensure fresh food is safely sent to consumption from production source
A kind of essential safeguard implemented in person's hand.
At present, the year demand of China's fresh agricultural products is about 400,000,000 tons, but due to the born perishable characteristic of agricultural product, and thing
Stream dispatching is generally carried out under normal temperature logistics, causes to be lost in logistics progress excessive.Fresh product is from the producer to finally disappearing
During the person of expense, the time for having 80% be have on logistics transportation 20% loss be occur in intermediate links.According to correlation money
Material display, due to inappropriate production, transport, stores the crop loss rate caused more than 20%, direct economic loss is about
100000000000 yuan.Therefore, the demand that effectively cold chain monitoring and tracing management how are carried out to fresh product is also more and more obvious.This
Just promote distributing fresh agricultural products mode to there occurs major transformation a bit, trigger and driven the hurried heating of Cold Chain Logistics.
In cold chain transportation process, refrigerator carriage ambient condition determines the length of fresh agricultural products storage period and shelf life, such as
What monitoring refrigerator carriage ambient parameter accurate, in real time, inexpensive is to ensure the pass that fresh agricultural products cold chain transportation is smoothed out
Key.And fresh and alive logistics is generally adopted by the carrier with refrigerator or similar safety cabinet etc to transport food, if often
The fresh and alive environment that loading space is tantamount to destroy food is opened, the acquisition of logistics information is received serious obstruction, and influence indirectly
The timely acquisition of logistics information, is unfavorable for Logistic Scheduling and grasps the information such as food state, geographical position in time.In addition, these
The medicine of the fresh and alive food of holding, agricultural product and the high-quality that are needed in system is unavoidable dirty by environment in multiple switching loading space
Dye, the reduction of hygienic quality likely results in hardly imaginable consequence.
Lorry scraps the time limit up to 15 years, with the fast development of technology of Internet of things, also has many original vehicles to be engaged in
Logistics works, and most refrigerator car only one of which warm areas, is attacked with net purchase spring tide, the retail vehicle for undertaking cold chain transportation is difficult
The goods for the same temperature range that gathers together enough, it is necessary to wait the source of goods for a long time, and it is rotten that the goods arrived first is easy for heating, it is necessary to enters
Row partition management.And for selecting the client of logistics provider, it is ensured that article is constantly in the state of temperature of requirement, accurate to grasp
Vehicle position information and ambient condition, the monitoring to whole link are highly desirable to.
There is patent research as follows:A kind of multi-temperature district refrigerator vans of suitable cold chain part load logistics of ZL 201610189225.5
Railway carriage or compartment, is changed in itself from car body, solves the function that same compartment includes a variety of warm areas, but can not be real-time to temperature
Monitoring, warm area temperature, which is still fallen within, can not review state.
A kind of fresh and alive logistics Internet of Things monitoring methods of ZL 201510162958.5, are by being installed on transport cases
RFID tag, and need in stream line mount message harvester in transit, early stage equipment investment is very big.
A kind of long-distance ice temperature On Transportaion of Live casees of ZL201510107378.6, simply car body and remote server use channel radio
Letter mode, specific sensor and controller are connected by IIC buses with the A/D capture cards, and wired mode limits its cloth
The flexibility put.
Therefore, in order to overcome problem present in fresh and alive logistics in the prior art, the intelligence degree of logistics net is lifted, is protected
Card food and medicine etc. is with lower O＆M cost and makes us more satisfied effect and is sent to destination, and the present invention proposes a kind of base
In the vehicle-mounted real-time monitoring system of passive and wireless cold chain transportation of Internet of Things.
