A kind of medicine storage transportation environment monitoring intelligent objectTechnical field
The invention belongs to Intelligent hardware and safety monitoring technology field, and in particular to one kind is used to store transport ring to medicineImplement the intelligent object of monitoring in border.
Background technology
Medicine is a kind of specialty goods, and qualified medicine must assure that drug quality, it is necessary to have the storage side of rigorous and scientificMethod and environmental requirement, medicine storage are improper, it may occur that physics, chemical change, reduce curative effect, adverse reaction increase, or even drawPlay life danger.Under any circumstance, it is necessary to which each transport, storage condition to medicine carry out environmental quality and implement tight prisonSurvey and scientific management.Therefore, it is quite important for the condition monitoring of medicine local environment, implement according to monitoring of environmental data to medicineThe real-time management of product turns into the compulsive requirement of national regulation.
The drug delivery of early stage, storage environment management system for monitoring are primarily directed to environment temperature in (1) transport vehicle carriageHumidity detection.(2) storage repository ambient temperature and humidity is monitored.It is a variety of medicines or big for concentrating on certain large area that it, which manages object,Single medicine in quantity set.Lack monitoring and early warning to the real time environment state residing for single case or single box medicine.
In the scheme of early stage, Temperature Humidity Sensor is distributed in some position of medicine storage repository or conveying carriage, soHumiture data transfer to data processing control units is analyzed and processed to data by wired connection mode afterwards, so thatReach the control to humiture.But such a control program installs complex, cumbersome, and mobility is poor, environmental monitoring data letterIt is single, it is unfavorable for implementing Precise control to the storage state and environmental condition of medicine.
Referring to accompanying drawing 1, in recent years, the management system monitored based on medicine storage environment, mostly using traditional humitureSensor detects the humiture parameter of surrounding environment, then adjusts temperature and humidity by controller, to reach storage medicine instituteIt is required that warm and humid angle value, meet storage environment requirement.Its scheme has following shortcoming：
1) traditional Temperature Humidity Sensor volume is big, installs inconvenient；
2) traditional Temperature Humidity Sensor installation site is relatively fixed, and mobility is poor；
3) connected between sensor and control system using wired mode, wiring installation is complicated, cost is high；
4) powered using civil power decompression or large-sized battery, cost is high, security is poor；
5) ambient parameter monitoring type is few, not comprehensive to the storage environment Indexs measure of medicine；
6) monitoring to the storage configuration of medicine-chest medicine box is lacked, as some medicine-chests, medicine box are unable to upside down；
7) application control system can be only put at certain fixed-site, it is necessary to which supervisor supervises by computer in real time, and shortage canMobile status.
The content of the invention
In order to overcome the existing medicine that is based on to store the problem of transportation environment management system for monitoring is present, the present invention provides onePlant medicine storage transportation environment monitoring intelligent object.The medicine intelligent storage environment monitoring module is supervised by a variety of ambient conditionsThe various parameters that sensor obtains storage environment are surveyed, and it is wireless by low-power consumption bluetooth (BLE, Bluetooth Low Energy)The various parameters of sensor are efficiently transmitted to data processing control center by transmission technology, and data processing control center can be passedThe fixed computer system of system or the mobile hand-held device (such as mobile phone) of user, pass through control platform on computer or mobile phoneOn APP control platforms read the parameters of various sensors and analyzed and processed and various controls can be sent to monitoring intelligent objectSystem order, realize whenever, effective monitoring of any place to medicine storage environment.
To realize above-mentioned target, the present invention uses following technical scheme：
A kind of medicine storage transportation environment monitoring intelligent object, the core of the intelligent object is to be based on the technology of bluetooth 4.0Low-power dissipation SOC (System-on-a-Chip, system integrated chip) single-chip, comprise additionally in antenna, match circuit, battery,RF (radio frequency) crystal oscillator, clock crystal oscillator, light sensor, baroceptor, motion sensor, temperature and humidity sensingDevice；The antenna is linked via match circuit with the SOC, other each modules respectively with the SOC chainConnect.
