Technical Field

Background
The interactive fluorescent stick or bracelet popular in the existing market provides the interactive function between audience and performers, and the activity planner can control the fluorescent stick or bracelet on the hands of the audience by using the wireless communication technology so as to achieve the change of synchronous light or special effect. The instant interactive control can change the original one-way viewing of the audience into two-way interaction with the performer, so that the audience can directly experience and integrate the mood to be conveyed by the performer.
The current interactive wireless communication system on the market can only change all around simultaneously, and can not realize individual or regional control. Some manufacturers have devised this visual illusion of individual or regional control by pre-recording programs or pre-arranging devices on the seats of the venue. Manufacturers also place non-repetitive numbers in the interactive devices, and then use the numbers as the basis of the control targets. However, these approaches share the problem that the audience carrying the interactive devices must remain in a stationary seat. If the spectator is not moving in a fixed seat or in an open-play type space, the system cannot correctly display the correct graphics, text or effects, and such a system cannot instantaneously correct or know the physical location of the mobile device.
Therefore, there is no multi-spot area wireless communication system and control method thereof in the market, which can change the light or function of the mobile device according to the relative position of the mobile device, so the related companies all seek to solve the problem.

Detailed Description
Various embodiments of the present invention will be described below with reference to the drawings. For the purpose of clarity, numerous implementation details are set forth in the following description. It should be understood, however, that these implementation details are not to be interpreted as limiting the invention. That is, in some embodiments of the invention, these implementation details are not necessary. In addition, for the sake of simplicity, some conventional structures and elements are shown in the drawings in a simple schematic manner; and repeated elements will likely be referred to using the same reference numerals.
Referring to fig. 1 to 3, fig. 1 is a schematic diagram illustrating a wireless communication system 100 with multiple points according to an embodiment of the invention. Fig. 2 is a block diagram of a wireless base station 200 of the multi-spot regional wireless communication system 100 of fig. 1. Fig. 3 is a block diagram of a mobile device 300 of the multi-spot area wireless communication system 100 of fig. 1. As shown, the wireless communication system 100 includes a plurality of wireless base stations 200 and a mobile device 300.
The wireless base station 200 comprises a wireless transmitter 210, a transmitting antenna 220, a second processor 230, and a communication interface 240. The wireless transmitter 210 transmits radio waves to the mobile device 300, and the radio waves carry the location identification code and the motion control code. The location identifier corresponds to the location of the wireless base station 200. Further, the transmitting antenna 220 signal-connects the receiving antenna 350 of the mobile device 300 and the wireless transmitter 210, and the transmitting antenna 220 transmits radio waves to the receiving antenna 350. The second processor 230 is in signal connection with the wireless transmitter 210 and can generate the location identification code and the motion control code. The location identifier represents the location information of the wireless base station 200, and the motion control code represents the motion command of the activity planner to control the mobile device 300 close to the wireless base station 200, which enables the operator 330 of the mobile device 300 to present the desired graphics, text or effect of the activity planner. The communication interface 240 is connected to an external terminal or control device by wireless or wired signal for the operation of the activity planner or performer. In addition, the number of the wireless base stations 200 is greater than or equal to 3, and the wireless base stations 200 determine the distribution positions and the number according to the field size. Each of the base stations 200 has a respective effective coverage area that is circular, the radius of the circle representing the farthest distance that the base station 200 can transmit signals. If the linear distance between the mobile device 300 and the wireless base station 200 exceeds the radius, it is difficult for the mobile device 300 to completely and quickly receive the radio wave transmitted from the wireless base station 200. To effectively and completely control the entire site, the activity planner needs to properly set up the radio base station 200 so that every corner of the site can be covered by the radio base station 200. It should be noted that, in order to ensure the rapid and reliable transmission of radio waves, the effective coverage areas of two neighboring radio base stations 200 overlap each other, so as to avoid generating a hollow area, which may cause incorrect graphics, text or effects of the mobile device 300 located in the hollow area due to incorrect actions.
The mobile device 300 comprises a body 302, a wireless receiver 310, a first processor 320, an actuator 330, a register 340, a receiving antenna 350, and a power circuit 360. The body 302 may be a fluorescent stick, a bracelet or a casing of a special prop, and the body 302 is connected to the actuator 330. The wireless receiver 310 is in signal connection with the wireless transmitter 210 through the receiving antenna 350 and the transmitting antenna 220 of the wireless base station 200, and receives radio waves from the transmitting antenna 220. The radio receiver 310 further includes a radio wave strength detecting unit 312, the radio wave strength detecting unit 312 can detect the strength of the radio wave to generate a radio wave strength value, and the number of the radio wave strength values can be plural, which respectively represent the influence relationship of the neighboring radio base stations 200 on the mobile device 300. Since the intensity of the radio wave is inversely related to the distance between the mobile device 300 and the wireless base station 200, the closer the mobile device 300 is to the wireless base station 200, the smaller the distance and the greater the intensity of the radio wave; conversely, when the distance between the mobile device 300 and the wireless base station 200 is larger, the radio wave intensity value is smaller, i.e. the intensity of the radio wave received by the mobile device 300 is weaker. In addition, the first processor 320 is connected to the wireless receiver 310 by signals, and the first processor 320 calculates the position signal of the wireless receiver 310 according to the radiowave strength value. The location signal corresponds to one of the wireless base stations 200, i.e., the location signal corresponds to the location identifier of one of the wireless base stations 200. In addition, the actuator 330 is connected to the first processor 320 by a signal, and the first processor 320 selects the corresponding motion control code to activate the actuator according to the corresponding location identification code. The actuator 330 may be a light source set, a vibrator, or a buzzer. The lamp source group comprises a plurality of light sources, and each light source has color, flicker frequency and light source intensity; the vibrator is used for vibrating the body 302; the buzzer is used for sounding. Through various types of actuators 330, the mobile device 300 can generate various effects, including visual, tactile and auditory effects, to make the viewer feel deep. Furthermore, the register 340 is also in signal connection with the first processor 320, and the register 340 stores the location identification code, the motion control code and the radiowave strength value. The receiving antenna 350 is connected to the wireless receiver 310 and receives radio waves. The power circuit 360 is electrically connected to provide power to the wireless receiver 310, the first processor 320, the actuator 330 and the register 340, so that the mobile device 300 can operate normally. It is worth mentioning that the foregoing radio wave strength values can be processed by the first processor 320 to perform a noise reduction operation, which can increase the noise ratio of each radio wave strength value. If the noise reduction operation is an averaging operation, the first processor can calculate an average radiowave strength value, and the first processor 320 can calculate the position signal of the wireless receiver 310 according to the average radiowave strength value. In detail, the plurality of radiowave strength values received by the mobile device 300 can be processed after being calculated by the first processor 320. For example, the average radiowave strength value may be an average of a plurality of radiowave strength values, which is calculated by adding the plurality of radiowave strength values and dividing by the number, which can offset errors caused by noise. In addition, the register 340 stores a predetermined average value and a tolerance range value, and the first processor 320 compares the average radio wave strength value with the predetermined average value. If the average radiowave strength value is larger than the preset average value and the difference between the two values exceeds the tolerance range value, the average radiowave strength value is excluded from being used as the basis for calculating the position signal. Of course, if the average radio wave intensity value is smaller than the preset average value and the difference between the two values exceeds the tolerance range value, the average radio wave intensity value is also excluded from being used. Therefore, by using the average operation, the preset average value and the comprehensive judgment of the tolerance range, not only the calculation error caused by the noise can be eliminated, but also the position signal of the wireless receiver 310 can be obtained more accurately. In addition, the noise reduction operation described above may employ other operations to reduce noise, such as: the low-pass filtering operation further makes the position signal of the wireless receiver 310 obtained after the operation more accurate.
Referring to fig. 3 and 4 together, fig. 4 is a schematic diagram illustrating a mobile device 300 according to the present invention in relation to four radio base stations 200a, 200b, 200c, 200 d. Wherein the mobile device 300 is located within the effective coverage of the wireless base stations 200b, 200d, and the mobile device 300 is closer to the wireless base station 200 b. As shown, the mobile device 300 is separated from the wireless base station 200a by a first distance D1; the mobile device 300 is separated from the wireless base station 200b by a second distance D2; the mobile device 300 is separated from the wireless base station 200c by a third distance D3; the mobile device 300 is separated from the wireless base station 200D by a fourth distance D4. The four pitches are sequentially a second pitch D2, a fourth pitch D4, a first pitch D1 and a third pitch D3 from small to large. The wireless base station 200a has a location identity p 1; the wireless base station 200b has a location identity p 2; the wireless base station 200c has a location identity p 3; the wireless base station 200d has a location identity p 4. The position identifiers p1 to p4 are all non-repeating identifiers. Since the second distance D2 is the smallest, the intensity of the radio wave detected by the radio wave intensity detecting unit 312 of the mobile device 300 is the strongest with the intensity of the radio wave transmitted by the radio base station 200 b. The first processor 320 in the mobile device 300 compares the magnitudes of the four radio wave strength values to select the maximum value of the radio wave strength values, which is from the radio base station 200 b. In addition, the first processor 320 generates a location signal according to the location identity p2 of the wireless base station 200b corresponding to the maximum value, so that the location signal corresponds to the location of the mobile device 300, and selects the action control code sent by the wireless base station 200b to activate the actuator 330. The position signal described above is the same as the position identification code p 2. Moreover, the motion control code has different information according to different types of the motion device 330, and if the motion device 330 is a light source group, the motion control code includes color information, flashing frequency information, and light source intensity information; if the actuator 330 is a vibrator, the motion control code includes vibration frequency information and vibration magnitude information; if the actuator 330 is a buzzer, the motion control code includes sound effect information. Of course, the above-mentioned various types can be mutually matched in the actuator 330, so that the mobile device 300 can present various effects.
Fig. 5 is a diagram illustrating the relationship between a mobile device 300 and five wireless base stations 200a, 200b, 200c, 200d, 200e according to the present invention. As shown, each of the wireless base stations 200a, 200b, 200c, 200d, 200e includes a wireless transmitter 210, and the wireless transmitter 210 transmits radio waves to the mobile device 300, and the radio waves carry two-dimensional coordinate data and two-dimensional matrix data. The two-dimensional coordinate data has a horizontal coordinate value X and a vertical coordinate value Y, and the two-dimensional coordinate data corresponds to the positions of the wireless base stations 200a, 200b, 200c, 200d, 200e, and the coordinates thereof are (X, Y), (X +1, Y), (X, Y-1), (X-1, Y), (X, Y +1), respectively. As can be seen from the above, the two-dimensional coordinate data represents "position coordinates of the wireless base station". The two-dimensional matrix data includes a plurality of matrix data, and each matrix data includes two-dimensional position coordinates and an operation control code. The two-dimensional position coordinates represent the coordinate positions of four quadrant regions, each region, divided by the wireless base station as the center of the circle. To effectively determine the precise location of the mobile device 300, the present invention provides a two-stage operation, which is a first stage operation and a second stage operation, and the two-stage operation is performed by the first processor 320, as described in detail below.
The first stage is that when the mobile device 300 receives a radio wave, the first processor 320 calculates a position signal of the wireless receiver 310 according to the radio wave strength value, wherein the position signal corresponds to the two-dimensional coordinate data of the wireless base station 200 a. In detail, the mobile device 300 is separated from the wireless base station 200a by a first distance D1; the mobile device 300 is separated from the wireless base station 200b by a second distance D2; the mobile device 300 is separated from the wireless base station 200c by a third distance D3; the mobile device 300 is separated from the wireless base station 200D by a fourth distance D4; the mobile device 300 is separated from the wireless base station 200e by a fifth distance D5. The five pitches are sequentially a first pitch D1, a second pitch D2, a third pitch D3, a fourth pitch D4 and a fifth pitch D5 from small to large. Since the first distance D1 is the smallest, the intensity of the radio wave transmitted by the radio base station 200a is the strongest, and the first processor 320 in the mobile device 300 generates the location signal according to the two-dimensional coordinate data (X, Y) of the radio base station 200a corresponding to the largest one of the intensity values of the radio wave, that is, the location signal includes the two-dimensional coordinate data (X, Y).
The second stage operation is that the first processor 320 further divides the effective coverage area of the wireless base station 200a into a first quadrant region a1, a second quadrant region a2, a third quadrant region A3 and a fourth quadrant region a4 according to the horizontal and vertical lines of the two-dimensional coordinate data (X, Y). And the two-dimensional position coordinates are located within the first quadrant region a1, the second quadrant region a2, the third quadrant region A3, or the fourth quadrant region a 4. After dividing the four quadrants, the first processor 320 compares the intensities of the electric waves between the mobile device 300 and the neighboring radio base stations 200b, 200c, 200d, 200e, and selects the first quadrant a1 where the two neighboring radio base stations 200b, 200c with stronger intensity are close to. The two-dimensional matrix data of the embodiment has four matrix data, and each matrix data comprises a two-dimensional position coordinate and an action control code; in other words, the two-dimensional matrix data has four two-dimensional position coordinates of (X + 1: Y +1), (X + 1: Y-1), (X-1: Y +1), and (X-1: Y-1), respectively. Furthermore, the first processor 320 calculates the position signal of the wireless receiver 310 of the mobile device 300 and selects the two-dimensional position coordinates (X + 1: Y-1) corresponding to the first quadrant region A1. The position signal is two-dimensional coordinate data (X, Y) combined with two-dimensional position coordinates (X + 1: Y-1), namely the position signal corresponds to the two-dimensional coordinate data (X, Y) and the two-dimensional position coordinates (X + 1: Y-1). Finally, the first processor 320 selects a corresponding action control code to start the action device 330 according to the two-dimensional coordinate data (X, Y) and the two-dimensional position coordinate (X + 1: Y-1) in the two-dimensional matrix data, and the action control code and the two-dimensional position coordinate (X + 1: Y-1) belong to the same matrix data. It is also worth mentioning that the two-dimensional matrix data may be larger matrix data in addition to the 2 × 2 size matrix data, such as: 3 × 3 or 4 × 4. The wireless transmitter 210 transmits larger and multi-level matrix data, which can be further subdivided into corresponding multiple levels according to the intensity of the electric wave, so that not only the position of the wireless receiver 310 can be accurately calculated by the first processor 320, but also the installation density of the wireless transmitter 210 can be reduced, and the system installation cost can be greatly reduced. Furthermore, the mobile device 300 can receive a plurality of sampled radiowave intensity values to precisely calculate the more precise and precise coordinates of the mobile device, so as to separate more areas from the effective coverage area of the wireless base station 200 a.
As can be seen from comparing fig. 4 and fig. 5, the mobile device 300 in fig. 4 receives the position identification codes p 1-p 4 and the operation control codes from the wireless base stations 200a, 200b, 200c, 200d, whereas the mobile device 300 in fig. 5 receives the two-dimensional coordinate data (X, Y), (X +1, Y), (X, Y-1), (X-1, Y), (X, Y +1) and the corresponding two-dimensional matrix data from the wireless base stations 200a, 200b, 200c, 200d, 200 e. No matter the radio wave received by the mobile device 300 is the position identification code together with the motion control code, or the two-dimensional coordinate data together with the two-dimensional matrix data, the mobile device 300 at a specific position can be controlled regionally, which not only brings convenience to the activity planner, but also can be more integrated into the performance situation of the performer for the audience. Furthermore, the viewer holding the mobile device 300 can still make the system present correct graphics, text or effects even if he leaves the original position, so that the viewer does not need to be confined to a fixed seat.
Referring to fig. 2, 3, 4 and 6, fig. 6 is a flowchart illustrating a control method 400 of the wireless communication system in a multi-spot area according to an embodiment of the invention, which is applied to the location identification codes p 1-p 4 and the action control codes of the wireless communication system in a multi-spot area of fig. 4. As shown, the method 400 for controlling the wireless communication system includes a sending step S11, a detecting step S12, a calculating step S13, a determining step S14 and a starting step S15. In step S11, each of the radio base stations 200 is controlled to transmit radio waves to the mobile device 300. The detecting step S12 is detecting the intensity of the radio wave to generate a radio wave intensity value. In the operation step S13, the position signal of the wireless receiver 310, that is, the position signal of the mobile device 300, is calculated according to the radiowave strength value. Further, the judgment step S14 is to judge whether the position identification codes p1 to p4 of the respective radio waves are identical to the position signals, and to select the identical position identification code p2 and the corresponding action control code. The activation step S15 activates the actuator 330 according to the actuation control code. Therefore, the control method 400 of the wireless communication system in the multi-spot area of the present invention can calculate the relative position of the wireless receiver 310 according to the intensity of the radio wave, and change the light or function of the mobile device 300 according to the position identification code p2 and the corresponding action control code, which not only brings certain convenience to the activity planner, but also can be more integrated into the performance situation of the performer for the audience.
Referring to fig. 2, fig. 3, fig. 5 and fig. 7 together, a flowchart of a control method 500 of a wireless communication system in a multi-spot area according to another embodiment of the present invention is shown, which is applied to two-dimensional coordinate data (X, Y), (X +1, Y), (X, Y-1), (X-1, Y), (X, Y +1) and corresponding two-dimensional matrix data of the wireless communication system in the multi-spot area of fig. 5.

The transmission step S21 is to control each of the radio base stations 200 to transmit radio waves to the mobile device 300.
The detecting step S22 is to generate a radio wave strength value by detecting the strength of the radio wave by the radio wave strength detecting unit 312 of the wireless receiver 310.
In the operation step S23, the location signal of the wireless receiver 310 is calculated according to the radiowave strength value. In detail, the operation step S23 includes a first stage operation and a second stage operation. In the first stage, when the mobile device 300 receives the radio wave, the first processor 320 calculates a position signal of the wireless receiver 310 according to the radio wave strength, wherein the position signal corresponds to the two-dimensional coordinate data (X, Y) of the wireless base station 200 a. The second stage operation is that the first processor 320 further divides the effective coverage area of the wireless base station 200a into a first quadrant region a1, a second quadrant region a2, a third quadrant region A3 and a fourth quadrant region a4 according to the horizontal lines and the vertical lines of the two-dimensional coordinate data (X, Y). After the four quadrant areas are divided, the first processor 320 compares the intensities of the electric waves and calculates the position signal of the wireless receiver 310 of the mobile device 300, and simultaneously selects the two-dimensional position coordinates (X + 1: Y-1) corresponding to the first quadrant area a 1. Finally, the first processor 320 selects a corresponding motion control code according to the two-dimensional coordinate data (X, Y) and the two-dimensional position coordinates (X + 1: Y-1) in the two-dimensional matrix data to control the motion controller 330.
The judgment step S24 is to judge whether the two-dimensional coordinate data of each radio wave is the same as the position signal, and select the same two-dimensional coordinate data and the corresponding two-dimensional matrix data. If the result of the step S24 is yes, that is, the two-dimensional coordinate data is the same as the position signal, then the step S25 is executed; on the contrary, if the result of the judgment step S24 is no, the transmission step S21 is re-executed.
The activation step S25 activates the actuator 330 according to the two-dimensional matrix data, that is, the activation step S25 activates the actuator 330 according to the motion control code corresponding to the two-dimensional position coordinate.
The recording step S26 is to store the two-dimensional coordinate data, the two-dimensional matrix data and the radiowave strength value into the register 340 and keep the latest data, such as: the latest 16 data are stored.
After the start step S25 and the recording step S26 are completed, the sending step S21 is re-executed within a fixed time, so that the mobile device 300 can update the correct motion control code at any time, and the system can maintain the correct graphics, text or effect.

Secondly, the technology of the invention can enable the spectator holding the mobile device to present correct graphics, characters or effects even if the spectator leaves the original position, so that the spectator does not need to be limited on a fixed seat. Thirdly, the intensity of the electric wave can be subdivided into a plurality of levels, and the electric wave can be matched with the wireless transmitter to transmit a larger data matrix corresponding to the levels, so that the installation density of the wireless transmitter can be reduced, and the cost can be greatly reduced. Fourthly, the mobile device can receive a large amount of sampled radio wave intensity values so as to precisely calculate the more precise and accurate coordinates of the mobile device.
Although the present invention has been described with reference to the above embodiments, it should be understood that various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the invention.
