The following describes the technical solution provided in the embodiments of the present application by taking a VR handle as an example.

The embodiment of the application provides a frequency adjustment method of a warning light, which is applied to a virtual reality VR handle, as shown in fig. 1, and the frequency adjustment method of the warning light may include the following steps 201 and 202:

step 201: the VR handle receives a first pulse signal transmitted by the ultra-wideband UWB base station.

The first pulse signal is generated by the UWB base station based on distance information between the VR handle and the wearable device, which is fed back by the IoT positioning device, and the distance information is calculated by the IoT positioning device based on positioning data of the VR handle and the wearable device, which are measured by the UWB base station.

Illustratively, the IoT positioning device described above may be an IoT positioning platform.

Illustratively, the wearable device may be a VR helmet that is matched to the VR handle, VR glasses that are matched to the VR handle, a display that is matched to the VR handle, or the like.

The IoT positioning device is configured to receive positioning data of the VR handle and the wearable device sent by the UWB base station, and calculate distance information between the VR handle and the wearable device based on the positioning data.

Illustratively, the VR handle and the wearable device are provided with positioning labels. The positioning tag is used for sending pulse signals to the UWB base station.

Illustratively, the UWB base station is configured to receive pulse signals sent by the VR handle and the positioning tag on the wearable device, and determine positioning data of the VR handle and the wearable device based on the pulse signals.

Illustratively, the UWB base station is coupled to the IoT positioning device through a power over ethernet PoE switch.

The PoE switch is connected to each UWB base station, and is used for data communication between the base station and the IoT positioning device, and can supply power to the UWB base station in PoE mode.

It should be noted that, above-mentioned UWB basic station sends the location data of VR handle and wearing formula equipment to IoT positioner through PoE switch, then, ioT positioner is based on above-mentioned location data, and the accurate distance information that calculates between VR handle and the wearing formula equipment through specific algorithm to send this distance information to UWB basic station through PoE switch, finally, UWB basic station sends the first pulse signal that this distance information corresponds to VR handle again.

Illustratively, the VR handle is provided with a UWB chip thereon. Wherein, the UWB chip is used for receiving the first pulse signal.

It can be appreciated that the VR handle may receive, through the UWB chip, a first pulse signal corresponding to distance information between the VR handle and the wearable device, which is transmitted by the UWB base station.

Optionally, in the embodiment of the present application, before the step 201, the method for adjusting the frequency of the indicator light provided in the embodiment of the present application further includes the following steps 401 and 402:

step 401: the VR handle receives a first input from a user.

Illustratively, the first input is a user input to a Home key on the VR handle.

Specifically, the first input is an input for activating the VR handle.

In this embodiment of the present application, the first input may be any one of the following: long press input, click input, voice input, gesture input, and the like.

Step 402, the VR handle activates the VR handle in response to a first input.

Illustratively, after activation of the VR handle, reception of the first pulse signal transmitted by the UWB base station may begin.

Step 202: the VR handle controls a flicker frequency of a cue light in the VR handle based on the first pulse signal.

Wherein, above-mentioned scintillation frequency is used for the distance between sign wearing equipment and the VR handle.

The first pulse signal is used for indicating distance information between the VR handle and the wearable device.

Illustratively, the indicator light may be an embedded single-chip microcomputer STM32LED light.

Illustratively, the UWB chip in the VR handle receives the first pulse signal and sends the first pulse signal to the STM32 singlechip in the indicator lamp, the STM32 singlechip uses a pulse width modulation PWM technique, outputs a PWM waveform corresponding to the pulse signal at an I/O port of the STM32 singlechip through a timer, and drives the indicator lamp to turn on or off (i.e., the flicker) similar to the breathing frequency based on a duty ratio of the PWM waveform. Wherein, the wave crest in the PWM waveform corresponds to a high level, namely the indicator lamp is lightened, and the wave trough in the PWM waveform corresponds to a low level, namely the indicator lamp is extinguished; the above duty ratio is used to indicate that the time of the high level occupies a percentage of the entire period within one pulse signal period.

It should be noted that, signal transmission can be performed between the UWB chip in the VR handle and the STM32 singlechip through NRF24L01 wireless communication mode, and SPI communication is adopted.

It should be noted that, if the signal width of the first pulse signal is larger, the faster the flicker frequency of the indicator light in the VR handle at this time, the closer the distance between the VR handle and the wearable device is indicated; if the signal width of the first pulse signal is smaller, the flicker frequency of the prompting lamp in the VR handle is slower, and the distance between the VR handle and the wearable device is longer.

Optionally, in the embodiment of the present application, the step 202 may specifically include the following step 202a:

step 202a: the VR handle adjusts the flicker frequency of the indicator light in the VR handle to a target flicker frequency based on the first pulse signal.

Wherein, the target flicker frequency is: a flicker frequency matching a signal width of the first pulse signal.

Illustratively, the signal width of the first pulse signal may be any one of the following: a first signal width, a second signal width, a third signal width, etc.

For example, the signal width of the pulse signal sent by the UWB base station and the flicker frequency have a correspondence relationship, and different signal widths correspond to different flicker frequencies.

The second signal width is larger than the first signal width, and the third signal width is larger than the second signal width.

Illustratively, the target flicker frequency may be any of the following: a first flicker frequency, a second flicker frequency, and a third flicker frequency.

Wherein the second flicker frequency is greater than the first flicker frequency, and the third flicker frequency is greater than the second flicker frequency.

Illustratively, the first flicker frequency may be a flicker frequency that matches a first signal width of the first pulse signal; the second flicker frequency may be a flicker frequency matching a second signal width of the first pulse signal; the third flicker frequency may be a flicker frequency matching a third signal width of the first pulse signal.

It can be understood that if the signal width of the first pulse signal received by the VR handle is larger, the flicker frequency of the indicator light in the VR handle is faster, and the closer the distance between the VR handle and the wearable device is; conversely, if the signal width of the first pulse signal received by the VR handle is smaller, the flicker frequency of the indicator light in the VR handle is slower, and the distance between the VR handle and the wearable device is longer.

So, because VR handle can be according to first pulse signal, with the scintillation frequency adjustment of warning light for the scintillation frequency that matches with first pulse signal's signal width, through above-mentioned scheme, VR handle can be according to the scintillation frequency suggestion user VR handle and the distance between the wearing formula equipment of warning light to guide the user to find the wearing formula equipment that matches with the VR handle fast.

Optionally, in an embodiment of the present application, the first pulse signal is used to indicate a distance between the VR handle and the wearable device.

The signal width of the pulse signal sent by the UWB base station is inversely proportional to the distance between the VR handle and the wearable device.

For example, if the signal width of the first pulse signal received by the VR handle is greater, the closer the VR handle is to the wearable device. Conversely, if the signal width of the first pulse signal received by the VR handle is smaller, the distance between the VR handle and the wearable device is further indicated.

Optionally, in the embodiment of the present application, after the step 202, the method for adjusting the frequency of the indicator light provided in the embodiment of the present application further includes the following step 301:

step 301: and under the condition that the distance between the VR handle indicated by the first pulse signal and the wearable device is smaller than a first threshold value, if the signal width of the received pulse signal in the preset time period is in a preset range, the prompting lamp in the VR handle is controlled to stop flashing.

It is understood that, in the case where the distance between the VR handle and the wearable device is smaller than the first threshold, if the signal width of the pulse signal received within the predetermined period is within the predetermined range, the signal width of the pulse signal received within the predetermined period may be considered to be stabilized. At this time, the indicator light in the VR handle stops flashing and is normally on, which indicates that the distance between the VR handle and the head-mounted device is within the range of distances that can be successfully paired and connected, so that the VR handle and the head-mounted device can be successfully paired and connected.

The first threshold may be set in advance by a user according to specific requirements, for example.

Wherein, the first threshold may be any one of the following: 5 meters, 6 meters, 7 meters, 8 meters, etc.

The predetermined range may be a value range preset by a user according to specific requirements, for example.

Wherein the predetermined range may be any one of the following: 0.085ns-0.095ns, 0.080ns-0.090ns, 0.090ns-0.095ns, etc.

The technical solutions provided in the present application will be exemplarily described below with specific examples.

s1, a UWB base station receives a pulse signal sent by a positioning tag, and positioning data of a VR helmet and a VR handle are obtained based on the pulse signal, wherein the VR helmet and the VR handle are respectively stuck with the positioning tag which can be identified by the UWB base station.

S3, the iot positioning platform calculates distance information between the VR helmet and the VR handle through a specific algorithm based on positioning data sent by the UWB base station, and sends the distance information to the UWB base station through the PoE switch.

S4, the UWB base station generates a first pulse signal based on the distance information fed back by the IoT positioning platform and sends the first pulse signal to the VR handle.

And S5, the UWB chip in the VR handle receives the first pulse signal sent by the UWB base station, and the flicker frequency of the prompting lamp is adjusted based on the signal width of the first pulse signal.

S6, when the distance between the VR helmet and the VR handle is smaller than a certain value, if the signal width of the pulse signal received in the preset time period is within a preset range, the prompting lamp in the VR handle is controlled to stop flashing and is normally on.

Taking the case that the positioning labels 24 which can be recognized by the UWB base station are attached to the VR handle 22 and the VR helmet 23, firstly, the UWB base station 21 receives the pulse signals sent by the VR handle 22 and the positioning labels 24 on the VR helmet 23, and calculates positioning data of the VR handle 22 and the VR helmet 23 based on the pulse signals, then, the UWB base station 21 sends the positioning data to the IoT positioning platform 26 through the PoE switch 25, then, the IoT positioning platform 26 calculates distance information between the VR handle 22 and the VR helmet 23 based on the positioning data, and sends the distance information to the UWB base station 21 through the PoE switch 25, secondly, the UWB base station 21 generates a first pulse signal based on the distance information and sends the first pulse signal to the VR handle 22, and in addition, the VR handle 22 receives the first pulse signal sent by the UWB base station 21 and controls the flicker frequency of the prompt lamp 29 in the VR handle 22 based on the first pulse signal, wherein the flicker frequency of the prompt lamp 29 is used for indicating distance between the VR handle and the VR helmet.
