Embodiment
Below in conjunction with accompanying drawing citing, the present invention is described in more detail:
A kind of Internet of Things temperature measurement system based on the wireless cooperation communication technology, its composition comprises compact processor system, temperature collect module, wireless receiving and sending module, cordless communication network, temperature collect module, LED display module, buzzer warning module and software module, and wherein software module comprises the module of temperature detecting module, wireless transmitter module, wireless receiving module, display module and alarm module and process abnormality.
It is characterized in that the combination superposition coordinated between software program.
It is characterized in that host computer system part comprises: wireless transceiver system, numeral method system and buzzer warning system, host computer system receives the temperature information data that send over from one of them slave system and then through the data of use numeral method received by it, after there is change in temperature, the display of charactron also rapidly collaborative variation show.
Composition graphs 1, Fig. 1 is overall system block diagram.Realize the simulation to Internet of things system, need the pattern that whole system simulation object-object is connected here, and communication for coordination each other, realize the process with abnormality of sharing of its information.So the design of whole system is mainly served as theme with temperature, realize the detection to temperature, then temperature monitored, report to the police and unusual condition process.Therefore the design of hardware circuit mainly designs around these aspects, and realize these functions.So just require to design three wireless communication systems that three wireless modules and Single Chip Microcomputer (SCM) system form here, realize the simulation of Internet of Things.Here by serviceability temperature, no matter this is in daily life, or in engineering practice, often need the intermediary mentioned as the information transmitted required for whole Internet of things system, in the design of this problem, here just use eaily temperature detection sensor DS18B20 as temperature acquisition element, coordinate low-power consumption, high performance single-chip microcomputer, adopt wireless transport module Nrf24L01 again to carry out transmission data, calculated by microprocessor again, the problems such as warning and abnormality process.Whole system is that the collection of temperature or the transmission of data are all conducive to engineering practice.In the design of whole system, we adopt the STC89C52 single-chip microcomputer produced by STC Corporation as the chip of master control, use high performance temperature probe, high performance radio receiving transmitting module and shown by charactron, form an alarm processing system by hummer and unusual condition again.
Composition graphs 2 is overview flow charts of slave system one.Slave system one mainly gathers temperature, then the temperature information collected is sent to host computer system, and then circulate this process gathering and send always.The Software for Design idea of this part is as follows: first must from initialization DS18B20 and wireless transmitter module (this does not have relation successively), then the temperature value that DS18B20 surveys is read, decimal number can be obtained after changing, get ten of temperature array and a position (because normal room temperature is no more than more than 100 degrees Celsius, therefore do not add hundred, and this problem does not consider that temperature is in subzero situation) write transmission data array, temperature data information is sent to host computer system.
Composition graphs 3, Fig. 3 machine overview flow chart.The system that host computer system part comprises has wireless transceiver system, numeral method system and buzzer warning system.Host computer system must receive the temperature information data that send over from one of them slave system and the data then through using numeral method received by it, after there is change in temperature, the display of charactron also rapidly collaborative variation show.When detect there are abnormal conditions time, host computer system can carry out buzzer warning, and issues another one slave system and send abnormality processing scheme.So the idea of the overall design of native system is such, first still obtains intiating radio and receive sending module Nrf24L01, then enter systemic circulation and judge whether status register has receive interruption.Just data are read from input into/output from cache if had, then convert data to the decimal system to show on charactron, after there are abnormal conditions, hummer there will be warning, and meanwhile, host computer system sends abnormality treating method to another slave system.
Composition graphs 4, Fig. 4 is slave system two process flow diagram.The program of this part is just relatively a bit simple, due to the limitation of real system, can only replace whether occurring abnormal conditions by the light on and off of light emitting diode in the process of this part of abnormality, and go timely to process unusual condition.When being in normal condition, green light on slave system; When there is unusual condition, when red on slave system.The thought of whole system Software for Design is as follows: we obtain first intiating radio module, receives the data sended over, judges whether to occur abnormality, show the state residing for whole system by the situation of bright light.
