It further, further include display screen, the display screen is electrically connected with processor.

It further, further include key module and bluetooth module, the key module is electrically connected with processor, the indigo plant Tooth module is connect with processor communication.

By using preceding solution, the beneficial effects of the utility model are: this intercom, which is based on block chain, encrypts skill Art, intercom transmitting radiofrequency signal need to encrypt by block chain, and the intercom for receiving radiofrequency signal needs to carry out block chain solution It is close to read information, guarantee the confidentiality of the intercommunication of intercom.

Detailed description of the invention

Fig. 1 is the circuit connection block diagram of the utility model embodiment.

Specific embodiment

Now in conjunction with the drawings and specific embodiments, the present invention will be further described.

With reference to Fig. 1, the present embodiment provides a kind of intercom based on block chain technology, packet handler 1, power module 2, PPT key 3, display screen 4, key module 5, loudspeaker 6, microphone 7, Receiver Module 8, radiofrequency emitting module 9, the 2nd A/ D-module 10, the first A/D module 11, the 2nd A/D module 12, the first A/D module 13, block chain public affairs spoon memory module 14, block chain Private spoon memory module 15, block chain algorithm processing module 16, bluetooth module 17.The processor 1 uses STM21L4 processor, The block chain public affairs spoon memory module 14 uses FLASH memory, and the block chain which contains this intercom is public The block chain public affairs spoon data of spoon data and other intercoms；The block chain private spoon memory module 15 is private using block chain is stored with The FLASH memory of spoon data, the block chain algorithm processing module 16 have the AT89C51 monolithic of hash algorithm using programming Machine.Above-mentioned each circuit components and circuit module are existing well-known technique, and the hash algorithm is well-known technique means.

The power module 2 is electrically connected with the power end of processor 1, and the display screen 4 is electrically connected with processor 1, described Key module 5 is electrically connected with processor 1, and the microphone 7 is electrically connected by the first A/D module 11 with processor 1, described to penetrate Frequency receiving module 8 is electrically connected by the 2nd A/D module 10 with processor 1, and the loudspeaker 6 passes through the first D/A module 13 and place It manages device 1 to be electrically connected, the radiofrequency emitting module 9 is electrically connected by the 2nd D/A module 12 with processor 1, the block chain public affairs spoon Memory module 14, block chain private spoon memory module 15, block chain algorithm processing module 16 and bluetooth module 17 respectively with processor 1 Communication connection.

Intercom working principle based on block chain technology is as follows: assuming that using the intercom A based on block chain technology It is communicated with intercom B, user can be manually entered the block chain public affairs spoon number of intercom B by the key module 5 of intercom A According to, and be stored in the block chain public affairs spoon memory module 14 of intercom A, display screen 4 is for showing that user passes through 5 hand of key module The data of dynamic input (are manually entered the block chain public affairs spoon data of intercom A by the key module 5 of intercom B, and are stored in In the block chain public affairs spoon memory module 14 of intercom B).Intercom A can also be with intercom B by bluetooth connection, and intercom B is logical Cross Bluetooth transfer techniques to intercom A conveying intercom B block chain public affairs spoon data, intercom A by Bluetooth transfer techniques to The block chain public affairs spoon data of intercom B conveying intercom A.

When intercom A sends voice messaging to intercom B, the workflow of intercom A are as follows: press the PPT of intercom A The microphone 7 of key 3, user against intercom A is talked, and the microphone 7 of intercom A receives voice messaging, passes through intercom A The first A/D module 11 be converted to the processor 1 that audio digital signals pass to intercom A, while the processor 1 of intercom A From saying that the block chain public affairs spoon memory module 14 of machine A extracts the block chain public affairs spoon data of intercom B, say the processor 1 of machine A from saying The block chain private spoon memory module 15 of machine A extracts the block chain private spoon data for saying machine A, then says that the processor 1 of machine A will be digital Voice signal, intercom B block chain public affairs spoon data pass, intercom A block chain private spoon data are delivered at the block chain algorithm for saying machine A Reason module 16 encrypted and signed, said machine A block chain algorithm processing module 16 encryption and signature after data back to The processor 1 for saying machine A gives intercom B finally by the transmitting of radiofrequency emitting module 9 radiofrequency signal for saying machine A.

The received workflow of intercom B are as follows: the Receiver Module of intercom B receives the radio frequency letter of intercom A transmitting Number, the processor 1 of machine B is said by saying that the 2nd A/D module 10 of machine B is converted to digital signal and passes to, while saying the processing of machine B Device 1 extracts intercom A block chain public affairs spoon data from the block chain public affairs spoon memory module 14 for saying machine B, says the processor 1 of machine B from saying The block chain private spoon memory module 15 of machine B extracts intercom B block chain private spoon data, then says that the processor 1 of machine B believes number Number, intercom B block chain public affairs spoon data pass, intercom B block chain private spoon data be delivered to the block chain algorithm processing module for saying machine B 16 are decrypted solution label.Data back after being said the decryption solution label of block chain algorithm processing module 16 of machine B is to the place for saying machine B Device 1 is managed, finally by 6 broadcast voice information of loudspeaker for saying machine B.

Based on the good confidentiality of the intercommunication of the intercom of block chain.
