Compared with similar controllers in the prior art, the digital camera synchronous outer flash lamp 2.4 G wireless remote controller provided by the utility model is not only advantaged by being simple in structure and convenient in operation, but also advantaged by being low in manufacture cost, convenient in utilization, high in reliability, and capable of guaranteeing the synchronous work of a camera wireless shutter and a shutter flash.
Description
Technical field
The utility model relates to a kind of wireless remote controller, particularly relates to the synchronous outer photoflash lamp 2.4G wireless remote controller of a kind of digital camera.
Background technology
At present, the fast gate technique of wireless remote control has become the sharp weapon of numerous Professional Photography user indispensabilities, and especially the manageability user, need to carry out moulding to the client and instruct, and perhaps directly catches beautiful moment, and the remote control shutter is undoubtedly best selection.Now on the market wireless shutter and the commodity of shutter flash synchronization be mostly a minute product on sale, it is that one is synthetic that a few product is also arranged, but market price is high, can't be not having shutter to draw use on the camera that dodges mouth, so existing technology and imperfection.
Summary of the invention
The purpose of this utility model is: provide a kind of simple in structure, safe and reliable, synchronous outer photoflash lamp 2.4G wireless remote controller of a kind of digital camera that can guarantee the wireless shutter of camera and the work of shutter flash synchronization, to overcome the deficiencies in the prior art.
The utility model is to consist of like this: the synchronous outer photoflash lamp 2.4G wireless remote controller of a kind of digital camera, comprise MEGA8 single-chip microcomputer and nRF24L01 type wireless transceiver that receiving terminal and transmitting terminal use, the output port of the MEGA8 single-chip microcomputer of transmitting terminal is connected with the input port of nRF24L01 type wireless transceiver, the output port of nRF24L01 type wireless transceiver is connected with the MEGA8 single-chip microcomputer input port of receiving terminal, and the output port of the MEGA8 single-chip microcomputer of receiving terminal is connected with the camera light diffuser with camera.
Owing to having adopted technique scheme, by receiving the input signal of single-chip nRF24L01 type wireless transceiver, the application software time-delay of MEGA8 single-chip microcomputer just can be synchronous with camera C CD; Compared with prior art, the utility model not only has advantage simple in structure, easy to operate, and has low cost of manufacture, and is easy to use, reliability is high, can guarantee the advantages such as the wireless shutter of camera and the work of shutter flash synchronization.

Description of reference numerals: 1-MEGA8 single-chip microcomputer, 2-nRF24L01 type wireless transceiver, 3-camera, 4-camera light diffuser.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment of the present utility model: the synchronous outer photoflash lamp 2.4G wireless remote controller of a kind of digital camera, comprise MEGA8 single-chip microcomputer 1 and nRF24L01 type wireless transceiver 2 that receiving terminal and transmitting terminal use, the output port of the MEGA8 single-chip microcomputer 1 of transmitting terminal is connected with the input port of nRF24L01 type wireless transceiver 2, the output port of nRF24L01 type wireless transceiver 2 is connected with MEGA8 single-chip microcomputer 1 input port of receiving terminal, and the output port of the MEGA8 single-chip microcomputer 1 of receiving terminal is connected with camera light diffuser 4 with camera 3.
Nordic company releases the low-cost single chip nRF24L01 type wireless transceiver 2 of a technical grade built in hardware link layer protocol, this device adopts the GFSK modulation, 128 frequency automatic frequency-hoppings, automatically generate header and CRC check code in sheet, have the automatic retransmitting function of makeing mistakes, it is low that these characteristics make the wireless system for transmitting data that is built by nRF24L0l have a cost, and speed is high, transmit the advantages such as reliable, first emission receives master chip to this product as 2.4G with nRF24L01 type wireless transceiver 2.
MEGA8 single-chip microcomputer 1 is existing a kind of integrated circuit (IC) chip.
The outer photoflash lamp 2.4G wireless remote controller of this digital camera synchronization passes to nRF24L01 type wireless transceiver 2 by signal of MEGA8 single-chip microcomputer 1 transmission of transmitting terminal, sent to again the MEGA8 single-chip microcomputer 1 of receiving terminal by nRF24L01 type wireless transceiver 2, when MEGA8 single-chip microcomputer 1 receives signal, the time-delay of shutter flash synchronization, wireless shutter and shutter flash synchronization at this moment
This product 2.4G wireless remote controller has following characteristics:
1. long transmission distance: can be greater than 50 meters opening scopes (open clear receives and the emission lower test result that remains static)
2. support point-to-point and multiple transmission mode point-to-multipoint, support the receiving terminal of unlimited amount
3. up to 16 optional frequency ranges, light avoid interference frequency: this product work has 16 optional frequencies in the ISM of 2.4GHz (i.e. industry, science, medical science) frequency range, can satisfy multifrequency and frequency hopping needs; For avoiding the easily impact of the interference of appearance on tonequality on the 2.4GHz common frequency band, this product provides the frequency selection function, to keep the good result of use of product.
4. the shortest fast gate delay, bring convenience to candid photograph
5. ultralow Consumption: provide industry minimum power consumption, during the transmitting terminal current work, at 40mA, arrival current is lower than 35mA, and under the stand-by operation state, electric current is less than 1 mA.
6. built-in aerial, strengthen the outer aesthetic feeling of closing.
7. can one camera, many photoflash lamps separate lighting.
