Based on the above, the visible light positioning system and the positioning method can be applied indoors, and the movement of the instruments and/or personnel can be effectively grasped through the server.

The above described features and advantages of the present invention will be more apparent from the following description.

The present disclosure proposes a mechanism for visible light positioning that utilizes a lighting fixture that is fixed in position in space to provide a reference point for location for positioning by instrumentation or personnel in space.

The luminaire of the present disclosure, for example, utilizes the illuminating form of the control luminaire to generate an optical signal in the form of a pulse, thereby emitting a specific identification code of the luminaire. In addition, the adjacent corresponding lamp identification code can be received by a positioning transceiver component that can be disposed on the movable instrument device or the person. Here, the positioning transceiver component itself also has another identification code. Therefore, the positioning transceiver component transmits the identification code of the lamp and the identification code of the positioning transceiver component itself to the server, for example, the connection mode of the wireless network, the server can locate the positioning transceiver component to provide positioning information.

Some implementation examples are described below, but the disclosure is not limited to the illustrated embodiment.

FIG. 1 is a schematic diagram showing a visible light positioning system according to an embodiment of the present disclosure. Referring to FIG. 1, the visible light positioning system 100 can include at least one light fixture 108 (eg, a plurality of light fixtures), at least one positioning transceiver component 106, and a servo 110. The server 110 is, for example, a cloud server. Each of the luminaires 108 is disposed at a specific location and has a first identification code, such as id ₁ , id ₂ , id ₃ , ..., id _{L , respectively} . In one embodiment, the luminaire 108 is a fixed location disposed on the ceiling of the indoor space, in addition to providing illumination, a reference location for positioning. The luminaire 108 assumes an open state or an off state, for example, by control, thus producing a bright or dark state. Thus in the form of a selected signal, which is, for example, in the form of a pulse, the first identification code of the luminaire is emitted. Each of the positioning transceiver elements 106 has a second identification code ID _n . Here, only one positioning transceiver element 106 is taken as an example. In practical applications, the number is generally plural but not limited, which is determined according to needs.

Herein, the "off state" of the luminaire can generally refer to a state of being completely closed. However, according to the demodulation capability of the positioning transceiver element 106, it is not necessary to be completely turned off, but a debounce state, as long as it can distinguish the "on state". That is to say, it can distinguish the high level from the low level.

The positioning transceiver component 106 can be disposed on a movable instrumentation or on a person 104. The instrumentation device 102 can include, for example, a health monitor, at least one of a physiological monitor, a fetal ultrasound monitor, a perfusion pump, a blood glucose meter, and the like. Regarding the manner in which the positioning transceiver component 106 is disposed on the person 104, for example, the positioning transceiver component 106 can be disposed on an identification card or other object carried by the person 104.

An example implementation of a detailed architecture for locating the transceiver component 106 will be described in greater detail below. Basically, the positioning transceiver component 106 includes a receiving component, movably receiving a corresponding one of the first identification codes, and demodulating the first identification code. The positioning transceiver component 106 further includes a wireless transceiver component for transmitting the first identification code id _i and the second identification code ID _n to a receiving end. This receiving end is, for example, a wireless network receiving end, and thus can be connected to the server 110.

The server 110 obtains the first identification code id _i and the second identification code ID _n by the receiving end, thereby positioning the positioning transceiver component 106 in the space defined by the luminaire 108.

The server 110 obtains the position of the luminaire having the first identification code id _i according to the database after receiving the first identification code id _i and the second identification code ID _n , for example, through a connection manner such as a wireless network. The location where the ID _n is located. In an embodiment, the server 110 may further transmit the data of the second identification code ID _n to the display panel 150 of the monitoring center, corresponding to the position of the building 152, indicating the positioning transceiver component 106 or the positioning positioning transceiver component 106.

FIG. 2 is a schematic diagram showing various configurations of the positioning transceiver component according to an embodiment of the disclosure. The positioning transceiver component 106 can generally be placed anywhere in the operating system, as long as it can receive the light emitted by the luminaire 108 and demodulate the first identification code. In practical applications, it is relatively necessary to monitor the movable object at any time. Thus, the positioning transceiver component 106 can be disposed on the instrumentation device 102 in an embodiment (see Figure 1). Other configurations can be combined, for example, with a helmet (see Figure 2), which is carried by the person 104 at any time. For another example, the instrumentation device 102 can also be an identification card carried by the person 104 (see FIG. 2), and the identification transceiver component 106 is also disposed on the identification card. That is to say, the positioning transceiver element 106 is arranged in such a way as to be placed on the movable object to be monitored. The arrangement of FIG. 2 is merely an implementation example, and is not intended to limit the scope of the disclosure.

FIG. 3 is a functional block diagram showing a light fixture 108 in accordance with an embodiment of the present disclosure. Referring to Figure 3, with respect to the functionality of the luminaire 108 disclosed herein, it can include a micro control unit (MCU) 200 as the center of control. The identification code setting interface 202 allows the fixture 108 to set its own identification code. For convenience of description, the identification code of the luminaire 108 is also referred to as a first identification code (id). In an embodiment, the micro control unit 200 can convert into a bit string according to the content of the first identification code, which is, for example, data containing 8 bits. The luminaire 108 has a plurality of illuminating elements 208, which may be, for example, illuminating diodes 208, but is not limited to illuminating diodes 208. The light state (on state) and the dark state (off state) of the light emitting diode 208 are regulated by a pulse signal, wherein the pulse signal corresponds to the bit string of the first identification code. That is, in an embodiment, the micro control unit 200 provides the bit data 204 of the first identification code to the lamp driver 206, and the lamp driver 206 generates a driving current to the light emitting device according to the “0” and “1” of the bit data 204. The polar body 208 controls the dark state and the bright state of the light-emitting diode 208 according to the timing, which corresponds to the content of the first identification code. In addition, the power source 210 provides the power required by the micro control unit 200 and the luminaire driver 206 and the like.

The embodiment of the present disclosure utilizes the mechanism of the dark state and the bright state of the luminaire 108 to transmit the content of the first identification code. In a further embodiment below, the first identification code is transmitted using a Manchester encoding format.

FIG. 4 is a schematic diagram showing the signal form of the Manchester encoding format according to an embodiment of the disclosure. Referring to FIG. 4, the Manchester encoding format is shown as a data area 250 of a plurality of bits of data, which is, for example, a data area 250 of 8 bits. There is a start area 230 in front of the data area 250 and an end area 240 behind the data area 250. That is, the start area 230 and the end area 240 define the data area 250. Taking 8 bits of data as an example, the data area 250 will contain 8 cycles. The "0" or "1" represented by each cycle is determined by the intermediate mode of transition. For example, the transition from the high level to the low level is "0", and the change from the low level to the high level is "1". The bit material of the embodiment of Fig. 4 is [11111111]. The identification code of the luminaire 108 will continue to be emitted, but due to the high frequency of change, the illumination of the illumination will not be substantially caused to the human eye.

It can be understood from the above description that for the visible light fixture for illumination, the function of transmitting the bit data can be realized by controlling the light state and the dark state to correspond to the high level and the low level of the bit data.
