Specific embodiment
Further explanation is done to the utility model with reference to the accompanying drawing.
As shown in Figure 1, a kind of interactive mode electric return board LED display light bar device, including controller, connector, Ruo Ganzhi
It can external control LED light source, gravity detector, speed detector, electric quantity detecting circuit.Intelligent external control LED is 20 WS2812 light sources,
The DO pin of previous WS2812 light source connects the DIN pin of latter WS2812 light source, and WS2812 light source sequentially forms series connection
Connection, as shown in Figure 2.The strip light band that 20 WS2812 light sources as shown in Figure 3 are formed is arranged at V-type, and strip light band passes through
PH2.0 connector is connected to controller.Strip light band is arranged in electric return board front-end surface, and is covered with transparency protected cover board.
Gravity detector includes the pressure sensor that nose and rear end is respectively set, and gravity detector is negative for detecting
It carries, and exports detection signal to controller.Specifically, the pressure sensor in gravity detector is strain chip pressure sensing
Device, gravity detector further include the A/D converter chip of model HX 711AD chip, two strain gauge pressure sensor groups
At bridge circuit, the input terminal of the output connection A/D converter chip of bridge circuit, the output end connection of A/D converter chip
To the signal input part of controller.HX711 be it is a aim at high-precision 24 A/D converter chips, integrated chip packet
Peripheral circuit required for other similar cake cores such as regulated power supply, on-chip clock oscillator is included, there is integrated level height, response speed
The advantages that degree is fast, strong interference immunity.There is low-noise programmable amplifier, optional gain is 64 and 128 in piece.
Speed detector is Hall sensor, for detecting the electric return board speed of service, and will test signal and is input to control
Device processed.Electric quantity detecting circuit is used to detect the battery module remaining capacity of electric return board, and will test signal and be sent to controller,
Controller can be STM32 controller.
