Accompanying drawing explanation
Fig. 1 is catenation principle schematic diagram of the present utility model.
Detailed description of the invention
As it is shown in figure 1, the carrier wave wireless dual mode communication device of a kind of band zero passage detection, including controller, controller connects
It is connected to power module, radio communication transceiver module, carrier communication transceiver module and zero passage detection module, radio communication transceiver module
Connecting and have antenna, antenna is for sending and receive the wireless signal of 470MHz, and carrier communication transceiver module is connected to power transmission line, mistake
Zero detection module is connected to power transmission line, and for the zero-crossing examination of ac grid voltage, antenna uses SMA communication interface, controls
Device uses STM32F chip.
Power module provides working power for whole system.
Controller can be operated according to the flow process of design for coordinating system components, and the model of controller chip is
STM32F。
Radio communication transceiver module: when there is the wireless signal of corresponding frequencies in medium, this signal can pass through external sky
Line is transferred to inside modules, then through a series of filtering and demodulation work, wireless signal is transformed to range signal and sends to
Controller processes and storage.Controller is sent to propagation medium by external antenna after data to be sent being processed.
Carrier communication transceiver module: when electric lines of force exists carrier signal, carrier wave receives and will receive with transtation mission circuit
Signal is demodulated after carrying out narrow-band filtering and amplitude limiting processing, and directly transmits a signal to controller, and controller is adopted by ADC
Sample obtains data and processes accordingly；When needs send data, data to be sent are used the side of BFSK by controller
Being sent to carrier wave after formula modulation receive and transtation mission circuit, carrier wave receives after being amplified by this signal with transtation mission circuit and is coupled in electrical network
Go.
Zero passage detection module uses 220V zero cross detection circuit, for the zero-crossing examination of ac grid voltage, it is achieved carry
The synchronicity of wave datum transmission, improves signal capacity of resisting disturbance.
The basic composition of 220V zero cross detection circuit: this 220V zero cross detection circuit is with diode halfwave rectifier and three
The on-off action of pole pipe is that ultimate principle designs, and wherein contains the good photoelectrical coupler of isolation performance and carries out forceful electric power and weak
The isolation of electricity, is effectively guaranteed the safety of weak electricity system.
The function of 220V zero cross detection circuit and advantage: when the alternating current 220V signal of telecommunication passes through from just half circumference negative half period conversion
The when of zero point, 220V zero cross detection circuit is at the moment by exporting a signal that can be identified to controller, to inform control
Device now electrical network is in zero point；Know when controller and just can carry out sending out of data in zero point when that when electrical network being in zero point
Send and carry out synchronizing to receive with this signal, so can improve stability and the reliability of carrier data communication, meanwhile, have 220V
Zero cross detection circuit also can effectively reduce the complexity of software design.
