Description
Technical field:
The present invention relates to the electronics technology field, particularly relate to the ZigBee transfer power line carrier wave gateway technology.
Background technology:
The ZigBee technology is the Radio Transmission Technology of a kind of low cost, low rate, low-power consumption, and it is based on the IEEE802.15.4 standard, and operating frequency is that 868MHz, 915MHz or 2.4GHz are the frequencies of an opening.ZigBee and other several wireless communication technologys are compared with Bluetooth as Wi-Fi, and outstanding feature is to use simply, and battery life is long, and networking capability is arranged, and reliability height and cost are low.
The contrast of ZigBee and other several wireless communication technologys
Performance: Wi-Fi Bluetooth ZigBee
The energy time-consuming: a hour meter day meter year counts
Complexity is very complicated simple
Network node 32 7 64000
30 milliseconds of maximum 3 seconds maximum 10 seconds reaction time
100 meters 10 meters 70-300 rice of scope
The long-range roaming of extensibility can not be expanded and can expand
Data rate 11Mbps 1Mbps 250Kbps
64 of fail safe service set identifier, 128 128 AES add
Close and the application layer user definition of safety certification safety certification meets the application of one of following condition usually, just can consider to adopt the ZigBee technology:
1. equipment cost is very low, and data quantity transmitted is very little;
2. equipment volume is very little, and bigger rechargeable battery or power module are placed in inconvenience;
3. do not have sufficient electric power support, can only use disposable battery;
4. change continually battery or repeatedly charging can't accomplish or very difficult;
5. need communication in a big way to cover, the equipment in the network is very many, but only is used for monitoring or control.
ZigBee is used in industrial environment automation, home automation and commercial building automation etc. mostly in the main application of industrial control field.At secure context, ZigBee defines in standard with 128bitAES as its encryption/decryption algorithm, and ZigBee can provide the user safest transmission environment.
ZigBee is controlled to be the master with building automation, Industry Control, household electrical appliances, also can replace traditional control transmission mode, as infra-red remote control is that available ZigBee replaces, and is more suitable for being used for designing the equipment that needs a large amount of cloth to build because ZigBee has the characteristic of low cost, low power consumption.
Other wireless technology of arranging in pairs or groups is expanded comprehensive application, because ZigBee itself also is not suitable for great amount of data transmission, it is not long to add transmission range, therefore other technology of all must arranging in pairs or groups in many application could develop total solution, for example: when mass data is transmitted, can see through WiFi, WiMAX or other technology, if then can arrange in pairs or groups GSM, GPRS, 3G, WiMAX or alternate manner when needing the length Distance Transmission, the function that whole application provided will be more perfect, and with respect to the needs of each stratum.IEEE802.15.4 and ZigBee can be used for making up and comprise thermostat, safety device and water, electricity, the wireless network of equipment such as coal gas read table.
Summary of the invention:
Purpose of the present invention will provide a kind of ZigBee transfer power line carrier wave gateway technology exactly, and it uses simple, and battery life is long, and networking capability is arranged, and reliability height and cost are low, and function is more perfect, satisfies necessary requirement.The object of the present invention is achieved like this, the ZigBee transfer power line carrier wave gateway technology is made up of power carrier transmission circuit, microprocessor, coupling transformer, it is characterized in that: whole gateway is respectively to connect coupling transformer, power carrier transmission circuit, microprocessor B, microprocessor A, ZigBee2.4GHz transmission circuit successively by power line from left to right, omnidirectional antenna or directional antenna, and the distribution of peripheral circuit.The present invention makes the transparent translation between power line and the wireless ZigBee become possibility, in the concrete construction of engineering, be fit to place power line carrier with power line, be fit to wireless place ZigBee, under the coordination of the technology of the present invention, well form a system, thereby promoted information automation.

Fig. 1 is a schematic diagram of the present invention;
Fig. 2 is the schematic diagram of a field monitoring;
1. power line, 2. coupling transformer, 3. power carrier transmission circuit, 4. microprocessor B, 5. microprocessor A, 6. transmission circuit, 7. antenna
Embodiment:
The invention will be further described below in conjunction with accompanying drawing;
In Fig. 1, the ZigBee transfer power line carrier wave gateway technology is made up of power carrier transmission circuit 3, microprocessor 1, coupling transformer 2, it is characterized in that: whole gateway is respectively to connect coupling transformer 2, power carrier transmission circuit 3, microprocessor B4, microprocessor A5, ZigBee2.4GHz transmission circuit 6 successively by power line 1 from left to right, omnidirectional antenna or directional antenna 7, and the distribution of peripheral circuit.During concrete enforcement, the power carrier transmission circuit is connected the physical layer that has realized the power line communication end, MAC layer and network layer with microprocessor A.The packet of receiving from the power line communication termination is by the I2C between microprocessor A and the microprocessor B, and interfaces such as UART are delivered to microprocessor B.ZigBee2.4GHz transmission circuit and microprocessor B have realized the ZigBee agreement of ZigBee communication terminal, finally launch by the ZigBee communication from the user data package that microprocessor A transmits.Otherwise, from the ZigBee communication terminal receive with the note packet by microprocessor B by the I2C between microprocessor A and the little treatments B, interfaces such as UART are delivered to microprocessor A, finally are transmitted on the power line network by the power line communication end.Clear in order to describe, little processing capacity is divided into microprocessor A and microprocessor B, and in force, it can be by a microprocessor physically, two microprocessors physically, or a plurality of physically microprocessor is finished.The power carrier transmission circuit is according to the used technology of power carrier communication net, can be for following several: narrowband carrier, spread spectrum, OFDM or power frequency communication.Used communications protocol also will with all the same of power carrier communication net.
In Fig. 2 embodiment, because cost is low, transmission is far away, ZigBee is widely used in the field monitoring field the sixth of the twelve Earthly Branches, but the ZigBee technology is not strong for the penetration capacity of barrier, and when having barrier such as mountain peak, building, dam in the monitoring of environmental, the ZigBee network just is separated easily and comes and can't communicate by letter.Ran into this situation in the past, and often had to adopt other wireless means such as GPRS to substitute ZigBee,, increased cost greatly though solved transmission problem.Utilize the ZigBee transfer power line carrier wave gateway technology, just can overcome the above problems.Still use ZigBee at opening, running into has barrier, then can use the ZigBee transfer power line carrier wave gateway technology, utilizes the power line that lays already that wireless signal is bridged to together.Because between ZigBee and the power line carrier is transparent transmission, for the ZigBee network, can't see the power line carrier span line at all, those two gateways are a ZigBee node In the view of it, thereby guaranteed the consistency of network, a low cost, scheme that reliability is high are provided.
