Embodiment 1:
The present invention is achieved by the following technical solutions:
Wireless sensor network in technology of Internet of things is used to be system architecture, the information communication mode using the stelliform connection topology configuration in ZigBee technology as system; Wherein wireless sensor network technology is equipped with energy module, signal transmitting and receiving module on a sensor, carries out the wireless telecommunications of data.
System mainly contains acquisition node, aggregation node, ZigBee telegon, host computer, and remote monitoring terminal forms.Acquisition node is responsible for the collection of signal and is sent by signal; All signal gatherings are sent to the ZigBee telegon of system in this by aggregation node; ZigBee telegon is a part in system and main, and it is used for monitoring whole network and normally works, and is the core of whole system, therefore needs to be equipped with abundant storage area to telegon, to ensure that it can normally complete various function.Signal sends computer to after telegon, arranges corresponding software program in computer, is equipped with display, the storage that other auxiliary equipment (as printer, warning device etc.) carry out completion system Monitoring Data on the one hand; Be connected with remote terminal by interconnected on the other hand, realize the remote monitoring of system.
Native system is electric power system, so need the data gathered to have environment and electric parameter two class data, just can have by these two classes data the comprehensive monitoring reached each side such as system running state, environment.Owing to have employed the modes such as simpler communications relatively in order to factor the design such as simplied system structures, all each acquisition nodes are relatively independent, and information can not occur mutually, can only pass through aggregation node indirectly communication.
Acquisition node and aggregation node all by CC2530 as control core, acquisition node and aggregation node are substantially identical on hardware configuration, therefore no longer independently repeat the hardware configuration of aggregation node.In order to make design have more versatility, the design uses modularized design thinking, makes this design can be general.Acquisition node and aggregation node are all by control module, wireless module, detection module, power module four parts.
Control module is the core of whole acquisition node, and it has needed the process of signal gathered, transmission, and the data wanting reception system to feed back to it, instruction, make corresponding action simultaneously.
Control module is made up of the auxiliary circuit of CC2530 and CC2530 outside, and CC2530 comprises mouthfuls 21, programmable I/0, in these programmable Is/O mouth, have 8 tunnels to be A/D interface, may be used for multiple sensor data acquisition and processing use.CC2530 chip is from the interface resetted containing, and outside can connect reset key and realize hardware initialization system.The external 32MHz crystal oscillator of CC2530 provides system clock, when can also connect 32.768kHz crystal oscillator for system hibernates.
Reset circuit designs: in system operation, not predictablely there will be some failure problems, work normally to make system, initialization etc., need to add reset circuit to system, button reset circuit is devised to this native system, by system reset initialization, be used for using in special circumstances, these measures ensure that the reliability of data.
Node mainboard normal DC operating voltage is 3.3V.Battery, USB, solar panel can be adopted to power to it, and USB powers and is applicable to directly connect computer, and solar powered have the features such as instability, less economical, structure is comparatively complicated, is unfavorable for the use of native system.Consider the aspects such as the power consumption of CC2530 is lower, system configuration, we directly adopt battery to power to it.Battery feed circuit as Figure 4-Figure 6.
Wireless module is in system very important, and it is responsible for signal transmitting and receiving.Following Railway Project must be considered: the signal of (1) wireless module, message transmission rate must meet the requirement of system at transceiver module; (2) wireless transmission will ensure to stablize, interference free performance is better.The design adopts microstrip balun circuit, and this design is single-ended 50 Ω the impedance transformation of radio RF pin differential signal.
Detection module gathers data, the bottom of whole system, most basic part, the accuracy of the data of detection module collection is related to series of problems such as the controls of system, so monitoring and important, must select the good transducer of accuracy.In the design, need the main physical parameters gathered to have: voltage, humiture, electrical power, electric current etc., can be increased other according to system real needs and gather flow stream parameters.As Figure 4-8, detection module sends processor to after utilizing river transducer acquisition parameter exactly.
The temperature sensor module of the design selects the TMP75 of TI company, TMP75 to be a low power consumption digital output temperature sensors.TMP75 has good accuracy and heat dispersion; Under low-power consumption energy state, consume energy less, only need use powered battery just can operate longer.What TMP75 adopted is two-wire serial interface, and its interface can be compatible with I2C.In encapsulation, TMP75 adopts 8 small and exquisite pin MSOP to encapsulate, and makes chip volume less.The pin 1,2 of TMP275 is two-wire serial interface, can be compatible with I2C bus interface, also can be directly coupled.When measuring tempeature exceed user's setting maximum temperature or lower than minimum temperature time, pin ALERT exports high level or low level [28].Above-mentioned 3 pins need pull-up resistor in reality connects.A0, A1 and A2 all connect low level, and the write address of such TMP275 device is 0x90, and reading address is 0x91.The warning way of output of TMP275 is set to low level output, is connected to pull-up resistor.
The design alternative Hall current of energy monitor module, voltage and power sensor.Hall element utilizes Hall effect produced, and the output waveform of current new device is comparatively complicated, and traditional sensors cannot detect, and the appearance of Hall bed transducer solves this problem, and Hall development potentiality is huge.Current Hall element, by being applicable to the aspect such as modern industry, control widely, common are and is applied to converter technique, intelligent grid, COMPUTER DETECTION etc.
Hall voltage transducer, Hall current sensor, Hall power sensor is had at the Hall element that native system is adopting.Beyond the inspection of traditional voltage, electric current, what will say especially is detection power module, detection power can be the independent, grid-connected as reference amount of system, when system send when power can not meet workload demand or send the larger load of power cannot digest voluntarily time, just can urge inverter is that system cuts grid-connect mode voluntarily, otherwise system power, workload demand balance just can independent operating.
Hall effect sensor connects: due to system voltage, electric current instability, in order to ensure the accuracy measured, can connect amplifier, ensure that system can by accurate measured value under less signal during measurement.
