Similar, when adopting positive n pyramidal structure as wideangle reflection face assembly, laser receiver can receive the laser in n direction.In actual implementation process, this wideangle reflection face assembly can only use at least two planes in positive n pyramidal structure to reflect laser, thus realizes the laser receiving assigned direction, and the present invention does not limit this.
Possible realize in scene at one, battle equipment is provided with simultaneously laser beam emitting device and laser receiver that above-described embodiment provides, and the transmission of laser is carried out by this device, wherein, this battle equipment can be Intelligent fighting toy car or Intelligent fighting toy aircraft etc.
As shown in Figure 5, it illustrates the schematic diagram that laser beam emitting device that one embodiment of the invention provides and laser receiver transmit laser process.
Laser beam emitting device 510 is arranged on the first battle equipment, and laser receiver 520 is arranged on the second battle equipment, and laser beam emitting device 510 and laser receiver 520 are positioned at sustained height.First battle equipment is by the Laser emission assembly 511 in laser beam emitting device, and to wideangle reflection face assembly 513 Emission Lasers 512 (straight up), this laser 512, after reflecting surface reflects, projects along horizontal direction.Laser 521 is incident upon the reflecting surface of wideangle reflection face assembly 521 in laser receiver 520, after this reflecting surface reflects, is incident upon the laser 512 that namely laser pick-off assembly 522, second battle equipment receive the first battle equipment transmission straight down.
As a kind of possible implementation, laser beam emitting device 510 and laser receiver 520 can be arranged on battle apparatus body top simultaneously, and also can be arranged on bottom battle apparatus body, the present invention is not set to position to it and limits simultaneously.The battle equipment being provided with above-mentioned laser beam emitting device and laser receiver can by other the battle equipment transmission laser of laser beam emitting device to all directions, the laser that other battle equipment that also can receive all directions by laser receiver sends.
When battle equipment needs by laser transmission data, laser modulation circuitry in battle equipment also needs to be electrical connected with the Laser emission assembly in laser beam emitting device, battle equipment is modulated laser by laser modulation circuitry in advance, then is launched the laser through ovennodulation by above-mentioned laser beam emitting device; Accordingly, laser demodulator circuit in battle equipment also needs to be electrical connected with the laser pick-off assembly in laser receiver, when being received the laser that other battle equipment is launched by laser pick-off assembly, the data demodulates of being carried by laser by laser demodulator circuit out, thus realizes the transmission of data between battle equipment.
Apparent, battle equipment only needs arrange the laser that a laser receiver can receive the transmission of all directions battle equipment, only needing, a laser beam emitting device is set and can fight equipment transmission laser to all directions, compared to light receiver assembly multiple on battle equipment and light emission assembly, the power consumption of battle equipment significantly can be reduced.
