The first radio frequency communications unit module uses CC1101 type long-range transceivers, passes through a SPI interface and the One main control unit module is communicated, and can improve transmission range in this way.
In this system between mobile phone, computer and server, between server and router, led to using standard network Letter;It is communicated using WLAN between router and concentrator.It is based on existing internet with uplink.Concentrator It is similar to a gateway within the system, one end connects Internet of Things, and the other end connects internet.It passes through Internet of Things and node It is communicated, Internet of Things includes:PLC and radio communication.Concentrator connects router by WLAN, then passes through internet It is communicated with server.Node is terminal device, compared with concentrator, does not have connection wireless lan function, only has PLC unit and radio frequency communications unit.Between concentrator and node by the way of PLC and radio communication.In the two communication, collection Middle device is main equipment, and node is from equipment;It is initiated to communicate first by main equipment.Since the transmission rate of PLC is low, radio frequency Data complete data transmission first.But needed after waiting for two class data to complete data transmission from equipment, it can just unify to return to number According to.For the transmission of PLC, the frame head of plc data is received and is judged, thus needs to expend more time;When After confirming that PLC frame heads are correct, the reception and judgement of data field can be then carried out from equipment, after all data successfully complete transmission, It is replied from equipment is unified to two kinds of transmission modes respectively.When computer or cell phone application need to inquire the electricity consumption data of a certain node When, system completes task by following steps:Computer, cell phone application are sent out " electricity consumption data of query node B1 " to server Request;Server issues " query node B1 " order by the concentrator of internet connecting node B1, and to concentrator;Concentrator By way of PLC and radio communication, querying command is issued to node B1;Node receives order, and passes through PLC and radio communication Mode return to electricity consumption data;After concentrator receives the data of node B1, storage is local and reports server by internet;Clothes Business device returns again to after receiving related data to computer or mobile phone, completes inquiry request.The present invention only has concentrator and needs WiFi Connection reduces network congestion, and in the invention, Internet of Things carries out data interaction with internet by concentrator, reduces router Connecting node quantity, reduce the congestion of network, enhance the stability of network.The present invention solves three-phase and four-line electric power networks Lower across the phase data transmission problems of PLC, the redundant channels as PLC of technology for radio frequency solve three-phase and four-line electric power networks Under, plc data transmits problem.
Working principle of the present invention is as follows:Cell phone application (being mounted on the software on smart mobile phone) module, WEB (global wide areas Net or WWW) between end module and server, between server and router, communicated using a kind of standard network;Road By being communicated using WLAN between device and concentrator;Server is used to obtain electricity consumption data and electricity consumption tariff information, Electricity consumption data and electricity consumption tariff information include total electricity, voltage, electric current, frequency, tariff data etc., and for payment mould to be arranged Formula, cyclic polling time supplement record with money, move in record, switch permission, operation log, the binding of equipment and unbundlings etc.;In this hair Bright middle concentrator is used as a gateway, and concentrator one end connects Internet of Things, and the other end connects internet, and concentrator passes through object Networking is communicated with node, and wherein Internet of Things includes PLC network and radio frequency network, and concentrator passes through WLAN link road It is communicated with server by device, then by internet;Node module is as terminal device in the present invention, with concentrator phase Than not having WiFi unit modules, only there is the second PLC unit module and the second radio frequency communications unit module;It is saved in the present invention Point module use environment is three-phase and four-line power network, and under the power utilization environment of three-phase and four-line power network, firewire and zero line-to-line load are very Weight, when the second PLC unit mould PLC in the block is carried out when communicating, signal decaying becomes larger, and PLC Communications failure rates is caused to get higher, Increase by the second radio frequency communications unit mould radio-frequency communication in the block on the basis of this, which solve concentrator and node module carry out across Communicate problem;PLC refers to utilizing existing power line, and signal is carried out to the technology of high-speed transfer, PLC features by carrier system It is that need not set up network again, as long as there is power line, data transfer can be carried out;Meanwhile long transmission distance;It is of low cost; These features determine that PLC is particularly suitable for the application of low speed Internet of Things;But when the heavier loads of power line network, channel Environment is deteriorated, and carrier signal decaying is serious, and then causes to communicate success rate reduction;Under the power line environment of three-phase and four-line, zero Line is common wire, and when progress is when communicating, modulated signal needs to be communicated by common wire, and common wire and three-phase firewire Between the relatively large load that adds up so that signal is decayed rapidly, and then lead to communication failure;Radio communication is one kind by being radiated space In the technology that is communicated of electromagnetic wave, due to the use of the channel for being independently of PLC therefore can be used as power line carrier The redundant channels of communication;And the present invention is using PLC by the way of adding radio communication, when PLC is carried out in Monophase electric power environment When data communicate, normal communication is can guarantee using PLC;When progress is when mutually transmitting, PLC and radio communication are used together, Ensure that data transmission is normal;Since the transmission rate of PLC is low, rf data completes data transmission first;But from setting It is standby to need after waiting for two class data to complete data transmission, it can just unify returned data;For the transmission of PLC, plc data Frame head is received and is judged, thus needs to expend more time;After confirming that PLC frame heads are correct, then can from equipment The reception and judgement for carrying out data field, after all data successfully complete transmission, respectively unify back two kinds of transmission modes from equipment It is multiple, it can solve under three-phase and four-line electric power networks in this way, plc data transmits problem, and reduces the connecting node number of router Amount, reduces the congestion of network, enhances the stability of network.
In conclusion the present invention solves under three-phase and four-line electric power networks, plc data transmits problem, and reduces routing The connecting node quantity of device, reduces the congestion of network, enhances the stability of network.
Particular embodiments described above, the technical issues of to the solution of the present invention, technical solution and advantageous effect carry out It is further described, it should be understood that the above is only a specific embodiment of the present invention, is not limited to The present invention, all within the spirits and principles of the present invention, any modification, equivalent substitution, improvement and etc. done should be included in this Within the protection domain of invention.
