[0035] AsFigure 1 and Figure 2 As shown in the figure, the friend-or-foe identification signal lamp comprises a shell 1, a power supply 2, a master control board 3, a master-slave dial 4, a mode button 5, an LED indicator 6 and a wireless communication module 7. The shell 1 has a receiving cavity and is provided with a light-transmitting part which can be made of full-transparent or semi-transparent material. The position of the light-transmitting part in the shell 1 can be determined according to the position of the light signal displayed in actual application, and the light signal can be observed from multiple directions. The position of the light-transmitting part is not limited in the embodiment.
[0036] The power supply 2 is connected with the shell 1. The power supply 2 can be a battery, such as a rechargeable lithium battery.

[0038] The master-slave dial 4 and the mode button 5 are arranged on the shell 1 and electrically connected with the master control board 3. The master-slave dial 4 can be provided with a master gear and a slave gear. The mode button 5 can be provided with an opening gear, a closing gear and a plurality of light signal selection gears.

It should be noted that the FPC connection cables can transmit both operating voltage (… Figure 3 In the FPC1 and FPC2 circuits, the thicker wires are power lines, and the thinner wires are signal lines, which can also transmit electrical signals. The first circuit board 31 is connected to the power supply 2 to power the various components in the first circuit board 31, the second circuit board 32, and the third circuit board 33. It should be noted that although... Figure 3 and Figure 4 The layout structure of the first circuit board 31, the second circuit board 32 and the third circuit board 33 in the housing 1 is shown. In practical applications, those skilled in the art can set different numbers of circuit boards and the positions of each circuit board in the housing 1 according to the specific structure of the IFF signal light. This embodiment does not limit the number and position of the circuit boards.
[0043] Optional, such as Figure 3 and Figure 4 As shown, the switch button 51 includes a tactile switch 511 and a keycap 512, and the gear knob 52 includes a gear switch 521 and a mechanical knob 522.

The position switch 521 is provided with multiple metal baffles 5211 arranged in a ring and a rotating blade 5212 driven to rotate by a mechanical knob 522. When the keycap 512 is pressed, the tactile switch 511 is triggered, causing the first circuit board 31 to generate a switch signal (turning the light on or off). When the mechanical knob 522 drives the rotating blade 5212 to rotate, the first circuit board 31 generates different position signals when the rotating blade 5212 contacts different baffles 5211 to indicate switching to different light signals.
[0045] like Figure 3 and Figure 4As shown, in one embodiment, the LED indicator 6 includes a first LED indicator 61 disposed on the second circuit board 32.

[0047] like Figure 3 As shown, the tactile switch receiver K1 and the gear switch receiver K2 of the MCU 330 are respectively connected to the third FPC connector 333 to receive the switching signals of the tactile switch 511 and the gear switch 521 through the second FPC (FPC2), the second circuit board 32, and the first FPC (FPC1). The RF terminals TX / RX of the MCU 330 are connected to the wireless communication module 7.

[0050] As shown in Figure 3 and Figure 4 , after the friend-or-foe identification signal lamp is powered on, the team leader dials the key body 41 of the friend-or-foe identification signal lamp worn on the team leader (team leader machine) to the master gear position, the master gear position sensor 421 in the gear position sensor 42 of the third circuit board 33 in the team leader machine outputs a signal to the MCU 330, the MCU 330 sets the team leader machine as the master, and the team members dial the key body 41 of the friend-or-foe identification signal lamp worn on the team members (team member machines) to the slave gear position, the slave gear position sensor 422 in the gear position sensor 42 of the third circuit board 33 in the team member machines outputs a signal to the MCU 330, the MCU 330 sets the team member machines as slaves, and each team member machine shields and disables the signals of the touch switch 511 and the gear switch 521 in the first circuit board 31, so that each team member cannot control the first LED indicator 61 and the second LED indicator 62 through the switch button 51 and the gear knob 52.
[0051] After the team leader machine turns on the first LED indicator 61 and the second LED indicator 62 through the switch button 51 and selects a light signal through the gear knob 52, the MCU 330 in the third circuit board 33 in the team leader machine receives the opening signal of the touch switch 511 in the first circuit board 31 and the light signal selected by the gear switch 521, and outputs a signal to the LED driving circuit 321 in the second circuit board 32, so that the first LED indicator 61 in the second circuit board 32 and the second LED indicator 62 in the third circuit board 33 are driven by the LED driving circuit 321 to open and display the light signal, at the same time, the MCU 330 in the third circuit board 33 in the team leader machine outputs a light mode selection signal to the wireless transceiver 71 in the wireless communication module 7, so as to send the opening signal and the light signal to each team member machine through the antenna 72.
