4th, system design Web ends or mobile phone terminal, using Baidu map api interface, the real-time exhibition first aid on network map
The parameters such as position, travel speed, the pressure value of oxygen cylinder of car, it is possible to intuitively shown and adopted by modes such as form, curves
The data collected.Meanwhile, control instruction is sent to by server by GPRS and communicated with equipment on emergency tender, realizes and uses
Family is in Web ends or mobile phone terminal On-line Control breathing equipment, and it is using interface referring to Figure 16, Figure 17.
The present embodiment additionally provides Remote data service method according to said system, comprises the following steps：
1) technology of Internet of things acquisition of information agreement is designed, calls API protocol to carry out request of data to front server, to passing
The facility informations such as sensor (sensor id, pressure value, Big Dipper location data etc.) are read out.
2) provided by userKey, apiKey, the parameter such as DeviceId, and the parameter needed carries out
JSON is encapsulated.
3) after the completion of encapsulating, set up and be connected with server by TCP, and encapsulation is completed using POST/GET methods
Data are uploaded.
4) service provider after receiving the request will returned data in time, the field of data first is flag, when flag is 00
Then show data successfully resolved, return to right value.If flag is not 00, shows that data processing fails, mistake is returned to, according to returning
The flag occurrences returned determine error reason and change program.Obtained if returning successfully its rule of correspondence JSON values (including
Hardware BEI-DOU position system return latitude and longitude value, and several pressure sensors return pressure value), finally by data processing
And insert in database server.
A kind of distant early warning method is designed in Remote data service method, this method is：Obtained in real time to front server
Take after a newest data, the latest data got and the threshold value of setting are contrasted, data are normal if finding, directly pass
Enter database.If discovery sensor numerical value exceeds threshold value, server will be serviced by Internet of Things remote access data storehouse
Device, the warning message exceeded, contact method and apiKey, message template etc. carries out data encapsulation, calls SMS platform
SDK, call alibaba.aliqin.fc.sms.num.send methods, by encapsulate complete data be sent to its platform service
Device.Its Platform Server, if passing through, will reach user, do not pass through after being verified to the request of this short message sending under information
Error code parameter is then returned, warning information is sent to this equipment manager and gas supplier in real time and records background data base clothes
Business device, notifies user to handle it.
The step 4 of above-mentioned Remote data service method) in, if receiving after correct JSON values, by calling PHP language
Json_decode methods in JSON storehouses are parsed to JSON data.After being parsed, JSON translates into dimension more than one
Group.Multidimensional numerical is parsed per one-dimensional by Foreach methods, if having demand can nested multiple Foreach methods to it
Parsed.After having parsed per data, the longitude and latitude degrees of data of pressure sensor and Big Dipper positioning can will be correctly got,
Now data value is judged, contrasted with threshold value, Warning Service is activated if data exception, client is given a warning.
By big-dipper satellite location data if data are normal, pressure sensor data carries out sql like language encapsulation, finally submits database clothes
Business device carries out execution real-time storage.
A kind of vehicle-mounted breathing equipment intelligent monitor system in emergency tender and its Remote data service provided above the present invention
Method.It is described in detail, in order to understand the present invention and its core concept.For those of ordinary skill in the art,
When it is implemented, a variety of modifications and deduction can be carried out according to the core concept of the present invention.In summary, this specification is not construed as
Limitation of the present invention.
