Specific embodiment
The following describes the present invention in detail with reference to the accompanying drawings and embodiments.
As shown in Figs. 1-2, a kind of family's blackboard with communication function, including blackboard body, built in the blackboard body
There is wireless data communication system, the wireless data communication system includes transmitting module and receiving module；The transmitting module packet
Transmitting main controller, transmitting RF device, transmitting filter circuit and transmitting antenna are included, the transmitting main controller is to connect the blackboard
The control system of ontology, and pass sequentially through the transmitting RF device, transmitting filter circuit, transmitting antenna and send data；
The receiving module includes receiving main controller, receiving RF device, wave reception filtering circuit and receiving antenna, and the reception main controller is used
To connect the control system of the blackboard body, and passing sequentially through the reception RF device, wave reception filtering circuit, receiving antenna will
External data receives.
Wherein, the transmitting main controller and reception main controller are all made of LPC2119 chip, the transmitting RF device and reception
RF device is all made of CC1200 chip, and the filter circuit and the model of wave reception filtering circuit of emitting is DAA1-6A, into one
Step ground, the transmitting module further includes clock module, and the clock module and the transmitting main controller are electrically connected.
Preferably scheme, the transmitting module further include reset key, the reset key and transmitting main controller electricity
Property connection.
Preferably scheme, the transmitting module further include serial port module, the serial port module and the transmitting master control
Device is electrically connected.
Preferably scheme, the serial port module are RS485 interfaces.
The workflow of lower transmitting module is briefly described below:
As shown in figure 3, transmitting main controller first starts to initialize, then blackboard control structure system after wireless data communication system work
Data to be sent are written in mission controller system, then emit main controller and construct data packet, after constructing data packet, need to judge
Whether the memory of transmitting RF device overflows, if overflowing the memory for needing to remove transmitting RF device, and writes the data packet hair
It penetrates in RF device memory.If do not overflowed, directly write the data packet in transmitting RF device memory.RF device will be emitted later
It is transformed into transmission state, until data packet is sent completely.
The workflow of lower receiving module is briefly described below:
As shown in figure 4, reception main controller first starts to initialize, and then judgement is received and penetrated after wireless data communication system work
Whether the memory of frequency device overflows, and needs to remove the memory for receiving RF device if overflowed, and reception RF device is transformed into and is connect
Receipts state.If do not overflowed, it will directly receive RF device and be transformed into reception state.Subsequently judge to receive whether RF device connects
Receive data, if receiving data, received data etc. RF device to be received, until finishing receiving, otherwise jump to by
It receives RF device and is transformed into reception state step.
