The utility model content
The purpose of this utility model is to provide the wireless remote control communication module that a kind of remote control distance is far away, the signal transmission reliability is high.
For achieving the above object, the utility model has adopted following technical scheme: a kind of wireless remote control communication module, the remote control receiving element that comprises remote-controlled launch unit and communication mutual with it, described remote-controlled launch unit comprises coding circuit, emission main control chip, radio-frequency transmissions circuit and power circuit, the emission main control chip links to each other with power circuit with coding circuit, radio-frequency transmissions circuit respectively, described remote control receiving element comprises decoding circuit, receives main control chip and radio-frequency (RF) receiving circuit, receives main control chip and links to each other with radio-frequency (RF) receiving circuit with decoding circuit respectively.
As shown from the above technical solution, the utility model utilizes radio-frequency transmissions circuit and radio-frequency (RF) receiving circuit, has solved the restriction of condition such as remote, complex-terrain to the remote signal remote control effectively; In addition, the coding circuit in the utility model, decoding circuit are encoded, are decoded order with the communications protocol that pre-defines, and have got rid of the possibility of false triggering and interference triggered basically, improve reliability of products and security.
Description of drawings
Fig. 1 is a circuit block diagram of the present utility model.
Embodiment
A kind of wireless remote control communication module, the remote control receiving element that comprises remote-controlled launch unit and communication mutual with it, described remote-controlled launch unit comprises coding circuit 1, emission main control chip 2, radio-frequency transmissions circuit 3 and power circuit 4, emission main control chip 2 links to each other with coding circuit 1, radio-frequency transmissions circuit 3 and power circuit 4 respectively, described remote control receiving element comprises decoding circuit 5, receives main control chip 6 and radio-frequency (RF) receiving circuit 7, receive main control chip 6 and link to each other with radio-frequency (RF) receiving circuit 7 with decoding circuit 5 respectively, as shown in Figure 1.The utility model utilizes radio-frequency transmissions circuit 3 and radio-frequency (RF) receiving circuit 4, solved the restriction of condition such as remote, complex-terrain to the remote signal remote control effectively.
As shown in Figure 1, described emission main control chip 2 links to each other with radio-frequency transmissions circuit 3 by communication interface, and described reception main control chip 6 links to each other with radio-frequency (RF) receiving circuit 7 by communication interface.Described emission main control chip 2 is communicated by letter with keyboard interface, and the signal output part of emission main control chip 2 links to each other with display, and described display adopts charactron.Described radio-frequency transmissions circuit 3 and radio-frequency (RF) receiving circuit 7 communications.Described power circuit 4 is respectively to emission main control chip 2, coding circuit 1 and 3 power supplies of radio-frequency transmissions circuit.The communications protocol that coding circuit 1 usefulness pre-defines is encoded to order, sends to emission main control chip 2 then and sends.After receiving main control chip 6 and receiving the order that emission main control chip 2 sends, give decoding circuit 5 data that receive, decoding circuit 5 is decoded to data according to agreement, and does which kind of action according to the requirement judgement of order.Which receiving end work keyboard interface can select by keyboard as the input end of order, also can pass through the keyboard input command, and which type of action the notice receiving end does.Display is used for showing current working state, the order that demonstration will send.
