The special things-internet gateway of refrigerating box based on big-dipper satellite positioning
Technical field
The present invention relates to internet of things field, and in particular to a kind of special Internet of Things of refrigerating box between big-dipper satellite positioning
Net gateway.
Background technology
In medical specimen centralized detecting business, medical specimen must be completed before the deadline from detection is collected,
It is detected not yet beyond the stipulated time, then its testing result is with regard to insincere.
Medical specimen is especially sensitive to temperature change, and for contingency, there is a situation where sample temperature to go beyond the scope, same meeting
Cause testing result insincere, can be diagnosed to medical institutions and bring erroneous judgement, it could even be possible to having serious consequences, for sample
Transport and storage have stringent temperature control requirement.
And lacks in the prior art and the whole real time temperature monitoring of refrigerating box progress for transporting medical specimen and position are chased after
The technological means of track.
Invention content
Goal of the invention:It is an object of the invention to solving the deficiencies in the prior art, provide it is a kind of controllably can pipe
It whole can trace the special things-internet gateway of refrigerating box based on big-dipper satellite positioning of monitoring.
Technical solution:A kind of refrigerating box special things-internet gateway based on big-dipper satellite positioning of the present invention, including be in
The gateway shell of sky setting, gateway primary module, Beidou positioning module and less radio-frequency receiving module are equipped in the gateway shell,
The location information of its acquisition gateway is transmitted to gateway primary module by Beidou positioning module, and less radio-frequency receiving module is by it from refrigeration
The temperature information that radio temperature sensor in case receives is transmitted to gateway primary module, and the gateway primary module will receive
The detection platform that location information and temperature information pass through GPRS transmission to server.
Further, be also useful in the gateway shell power supply lithium battery, gateway shell be equipped with for open and
Close the switch button of gateway.
Further, the less radio-frequency receiving module is connected and is communicated with gateway primary module by the side's I C agreements.
Further, in the Beidou positioning module data transmission pin of positioning chip directly with gateway primary module phase
Even.
Further, the radio temperature sensor was launched every 10 seconds in refrigerating box by 780M antennas
The radiofrequency signal of temperature data, after less radio-frequency receiving module receives after the radiofrequency signal real-time Transmission to gateway main mould
Block.
Further, the Beidou positioning module received the location information of refrigerating box every 20 seconds from big-dipper satellite, and
Real-time Transmission is to gateway primary module.
Further, it is additionally provided with expelling plate and receiving coil on the gateway shell, the expelling plate is internally provided with several
Coil array generates magnetic field and simultaneously transfers energy to receiving coil, the receiving coil by the energy received be converted to for
The electric energy of gateway power supply.
Advantageous effect:The present invention can monitor and transmit in real time the location information and temperature information of refrigerating box:Convenient for user
Medical specimen in real-time management refrigerating box and refrigerating box.
Specific implementation mode
Technical solution of the present invention is described in detail below, but protection scope of the present invention is not limited to the implementation
Example.
A kind of special things-internet gateway of refrigerating box based on big-dipper satellite positioning of the present invention, includes the net in hollow setting
Shell 1 is closed, gateway primary module, Beidou positioning module and less radio-frequency receiving module, Beidou positioning module are equipped in gateway shell 1
The location information of its acquisition gateway is transmitted to gateway primary module, less radio-frequency receiving module is by it from wireless in refrigerating box 2
The temperature information that temperature sensor 3 receives is transmitted to gateway primary module, and gateway primary module is by the location information received and temperature
Degree information passes through GPRS transmission to the detection platform of server 5.
Wherein, the lithium battery of power supply is also useful in gateway shell 1, gateway shell 1 is equipped with for opening and closing net
The switch button of pass;Expelling plate and receiving coil are additionally provided on gateway shell 1, expelling plate is internally provided with several coil arrays and generates
Magnetic field simultaneously transfers energy to receiving coil, and the energy received is converted to the electric energy for powering to gateway by receiving coil.
Entire things-internet gateway can not only be made by lithium battery power supply but also by wireless power, the abundance of the power supply of guarantee as a result,
With flexible.
Less radio-frequency receiving module in the present embodiment is connected and is communicated with gateway primary module by the side's I C agreements.
The data transmission pin of positioning chip is directly connected with gateway primary module in Beidou positioning module in the present embodiment;
Beidou positioning module received the location information of refrigerating box 2 every 20 seconds from big-dipper satellite 4, and real-time Transmission is to gateway main mould
Block.
Wherein, radio temperature sensor 3 was launched every 10 seconds with the temperature data in refrigerating box 2 by 780M antennas
Radiofrequency signal, after less radio-frequency receiving module receives after the radiofrequency signal real-time Transmission to gateway primary module.
The specific workflow of the present invention is as follows:
The gateway shell 1 of the special things-internet gateway of refrigerating box of the present invention is installed on refrigerating box 2, and in refrigerating box 2
Inside installation radio temperature sensor 3,2 special things-internet gateway of refrigerating box is formal after opening the switch button on gateway shell 1
Start.3 real-time detection of radio temperature sensor acquires the temperature in refrigerating box 2, and is launched every 10 seconds by 780M antennas
Radiofrequency signal with the temperature data in refrigerating box 2, the radio frequency that the less radio-frequency receiving module in gateway shell 1 will receive
Signal transmission is to gateway primary module;Meanwhile big-dipper satellite 4 issued Big Dipper positioning mould every 20 seconds location informations by refrigerating box 2
The location information received is uploaded to gateway primary module by block, Beidou positioning module;The position that last gateway primary module will receive
Confidence ceases and temperature information is transmitted to the monitor supervision platform on server 5 by way of GPRS, and administrative staff or user can
2 live state information of refrigerating box is monitored on server 5.
