Please refer to FIG. 1 to FIG. 3 together. FIG. 1 is a schematic diagram of a multi-point area wireless communication system 100 according to an embodiment of the present invention. 2 is a block diagram of a wireless base station 200 of the multi-point area wireless communication system 100 of FIG. Figure 3 is a block diagram showing the mobile device 300 of the multi-point area wireless communication system 100 of Figure 1. As shown, the multi-point area wireless communication system 100 includes a plurality of wireless base stations 200 and a mobile device 300.

The wireless base station 200 includes a wireless transmitter 210, a transmitting antenna 220, a second processor 230, and a communication interface 240. The wireless transmitter 210 transmits a radio wave to the mobile device 300, and the radio wave carries a location identification code and an action control code. The location identification code corresponds to the location of the wireless base station 200. Further, the transmitting antenna 220 is connected to 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 then connects to the wireless transmitter 210 and can generate a location identification code and an action control code. The location identification code represents the location information of the wireless base station 200, and the action control code represents the activity planner to control the proximity to the wireless base. The action command of the mobile device 300 of the station 200 allows the action 330 of the mobile device 300 to present a graphic, text or effect desired by the event planner. As for the communication interface 240, the external terminal or control device is connected by wireless or wired signal for the event planner or performer to control. In addition, the number of wireless base stations 200 is greater than or equal to three, and the wireless base station 200 determines the location and number of distributions depending on the size of the venue. Each of the wireless base stations 200 has its own effective coverage, and the effective coverage is a circle. The radius of the circle represents the farthest distance that the wireless base station 200 can transmit signals. If the linear distance of the mobile device 300 from the wireless base station 200 exceeds this radius, the mobile device 300 will have difficulty receiving the radio waves transmitted by the wireless base station 200 in a complete and rapid manner. In order to effectively and completely control the entire venue, the event planner needs to properly set up the wireless base station 200 so that each corner of the venue can be covered by the wireless base station 200. In addition, it is worth mentioning that in order to ensure that the transmission of radio waves can be quickly and surely, the effective coverage ranges of the two adjacent wireless base stations 200 overlap each other to avoid the generation of a cavity area, so that the mobile device 300 located in the cavity area is Incorrect motion causes the wrong graphic, text, or effect to occur.

The mobile device 300 includes a body 302, a wireless receiver 310, a first processor 320, an operator 330, a temporary memory 340, a receiving antenna 350, and a power circuit 360. The body 302 can be a housing of a fluorescent stick, a bracelet or a special item, and the body 302 is connected to the actuator 330. The wireless receiver 310 is connected to the wireless transmitter 210 via the receiving antenna 350 and the transmitting antenna 220 of the wireless base station 200, and receives the wireless transmitter 210. Radio waves from the transmitting antenna 220. Moreover, the wireless receiver 310 includes a radio wave intensity detecting unit 312. The radio wave intensity detecting unit 312 can detect the intensity of the radio wave to generate a radio wave intensity value, and the number of the radio wave intensity values can be plural. Representing the influence relationship of the adjacent plurality of wireless base stations 200 on the mobile device 300. Since the radio wave intensity value is negatively correlated with the distance between the mobile device 300 and the radio base station 200, the closer the mobile device 300 is to the radio base station 200, the smaller the pitch and the greater the radio wave intensity value; conversely, when the mobile device The larger the distance between the 300 and the wireless base station 200, the smaller the radio wave intensity value, that is, the weaker the intensity of the radio wave received by the mobile device 300. In addition, the first processor 320 is connected to the wireless receiver 310, and the first processor 320 calculates the position signal of the wireless receiver 310 according to the radio wave intensity value. The location signal corresponds to one of the plurality of wireless base stations 200, that is, the location signal corresponds to the location identification code of one of the wireless base stations 200. In addition, the actuator 330 is connected to the first processor 320, and the first processor 320 selects a corresponding action control code according to the corresponding location identification code to activate the actuator. The actuator 330 can be a light source set, a vibrator or a buzzer. The light source group includes a plurality of light sources, each light source has a color, a blinking frequency and a light source intensity; the vibrator is used to vibrate the body 302; and the buzzer is used to sing. Through various types of actuators 330, the mobile device 300 can produce a variety of rich effects, and these effects cover the visual, tactile, and auditory aspects, allowing the viewer to go deep into the environment. Moreover, the temporary memory 340 is also connected to the first processor 320, and the temporary memory 340 stores the location identification code, the motion control code, and the radio wave intensity value. As for the receiving antenna 350, the signal is connected to the wireless receiver 310 and receives radio waves. The power circuit 360 is electrically connected and provides power to the wireless receiver 310, the first processor 320, the actuator 330, and the temporary storage memory 340 to enable the mobile device 300 to operate normally. It is worth mentioning that the aforementioned radio wave intensity value can be performed by the first processor 320 to perform a noise reduction operation, and the noise reduction operation can increase the signal to noise ratio of each radio wave intensity value. If the noise reduction operation is an averaging operation, the first processor can calculate an average radio wave intensity value, and the first processor 320 can calculate the position signal of the wireless receiver 310 according to the average radio wave intensity value. In detail, the plurality of radio wave intensity values received by the mobile device 300 can be processed by the operation of the first processor 320. For example, the average radio wave intensity value may be an average of multiple radio wave intensity values, and the average operation is obtained by adding multiple radio wave intensity values and dividing by the number, which can eliminate the error caused by the noise. . In addition, the temporary memory 340 stores a preset average value and a tolerance range value, and the first processor 320 compares the average radio wave intensity value with a preset average value. If the average radio wave intensity value is greater than a predetermined average value and the difference between the two exceeds the tolerance range value, then the average radio wave intensity will be excluded without using the basis for calculating the position signal. Of course, if the average radio wave intensity value is less than a predetermined average value and the difference between the two exceeds the tolerance range value, the average radio wave intensity value is also excluded from use. Thereby, the comprehensive judgment using the average calculation, the preset average value, and the tolerance range value can not only eliminate the calculation error caused by the noise, but also obtain the position signal of the wireless receiver 310 more accurately. In addition, the above-mentioned noise reduction operation can be performed by other operations. Low noise, for example, low-pass filtering operation, makes the position signal of the wireless receiver 310 obtained after the operation more accurate.

Please refer to FIG. 3 and FIG. 4 together. FIG. 4 is a schematic diagram showing the relationship between a mobile device 300 and four wireless base stations 200a, 200b, 200c, and 200d according to the present invention. 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 200b. As can be seen from the figure, 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; and the mobile device 300 The fourth pitch D4 is separated from the wireless base station 200d. The above four pitches are, in order from small to large, the second pitch D2, the fourth pitch D4, the first pitch D1, and the third pitch D3. The radio base station 200a has a position identification code p1; the radio base station 200b has a position identification code p2; the radio base station 200c has a position identification code p3; and the radio base station 200d has a position identification code p4. These position identification codes p1 to p4 are identification codes that are not repeated. Since the second pitch D2 is the smallest, the radio wave intensity detected by the radio wave intensity detecting unit 312 of the mobile device 300 is the strongest in the radio wave intensity transmitted by the radio base station 200b. The first processor 320 in the mobile device 300 compares the magnitudes of the four radio wave intensity values to select a maximum value among the radio wave intensity values from the wireless base station 200b. In addition, the first processor 320 generates a location signal according to the location identification code 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 wireless base station 200b. The action control code is sent to cause the actuator 330 to start. The above position signal is the same as the position identification code p2. Furthermore, the action control code has different information according to different types of the action device 330. If the action device 330 is a light source group, the action control code includes color information, blinking frequency information, and light source intensity information; For the vibrator, the motion control code includes vibration frequency information and vibration size information; if the actuator 330 is a buzzer, the motion control code includes sound effect information. Of course, the above various types can be matched with each other in the actuator 330, so that the mobile device 300 can exhibit a variety of effects.

Figure 5 is a diagram showing the relationship between a mobile device 300 of the present invention and five radio base stations 200a, 200b, 200c, 200d, and 200e. As shown, each of the wireless base stations 200a, 200b, 200c, 200d, 200e includes a wireless transmitter 210, and the wireless transmitter 210 transmits a radio wave 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 axis coordinate value X and a vertical axis coordinate value Y, and the two-dimensional coordinate data corresponds to the positions of the wireless base stations 200a, 200b, 200c, 200d, and 200e, and the coordinates are respectively (X, Y), (X+1, Y), (X, Y-1), (X-1, Y), (X, Y+1). As can be seen from the above, the two-dimensional coordinate data represents the "position coordinates of the wireless base station". In addition, the two-dimensional matrix data has a plurality of matrix data, and each matrix data includes a two-dimensional position coordinate and an action control code. This two-dimensional position coordinate represents "four quadrant areas divided by the wireless base station as the center, and the coordinate position of each area". In order to effectively determine the precise location of the mobile device 300, the present invention proposes a two-stage operation, which is a first-stage operation In conjunction with the second stage operation, the two-stage operation is performed by the first processor 320, as detailed below.

The first stage operation is that when the mobile device 300 receives the radio wave, the first processor 320 calculates the position signal of the wireless receiver 310 according to the radio wave intensity value, and the position signal corresponds to the two-dimensional coordinate data of the wireless base station 200a. . In detail, the mobile device 300 is separated from the wireless base station 200a by a first spacing D1; the mobile device 300 is separated from the wireless base station 200b by a second spacing D2; the mobile device 300 is separated from the wireless base station 200c by a third spacing D3; the mobile device 300 is The wireless base stations 200d are separated by a fourth spacing D4; the mobile device 300 is separated from the wireless base station 200e by a fifth spacing D5. The above five pitches are, from small to large, a first pitch D1, a second pitch D2, a third pitch D3, a fourth pitch D4, and a fifth pitch D5. Since the first interval D1 is the smallest, the radio base station 200a transmits the strongest radio wave intensity, and the first processor 320 in the mobile device 300 according to the maximum value of the radio wave intensity values corresponds to the two-dimensionality of the radio base station 200a. The coordinate data (X, Y) is used to generate the position signal, that is, the position signal contains two-dimensional coordinate data (X, Y).

The second stage computing system first processor 320 further separates the effective coverage of the wireless base station 200a into the first quadrant area A1 and the second quadrant area A2 according to the horizontal and vertical lines of the two-dimensional coordinate data (X, Y). Three-quadrant area A3 and fourth quadrant area A4. The two-dimensional position coordinates are located in the first quadrant area A1, the second quadrant area A2, the third quadrant area A3, or the fourth quadrant area A4. After dividing the four quadrant regions, the first processor 320 compares the mobile device 300 with the neighboring wireless base The radio wave intensity between the ground stations 200b, 200c, 200d, and 200e selects the first quadrant area A1 in which the two adjacent wireless base stations 200b and 200c are strong. The two-dimensional matrix data of this embodiment has four matrix data, each matrix data includes a two-dimensional position coordinate and an action control code; in other words, the two-dimensional matrix data has four two-dimensional position coordinates, respectively (X+1: Y+1), (X+1: Y-1), (X-1: Y+1), and (X-1: Y-1). Moreover, the first processor 320 calculates a position signal of the wireless receiver 310 of the mobile device 300, and simultaneously selects a two-dimensional position coordinate (X+1: Y-1) corresponding to the first quadrant area A1. The position signal is two-dimensional coordinate data (X, Y) combined with two-dimensional position coordinates (X+1: Y-1), that is, the position signal corresponds to two-dimensional coordinate data (X, Y) and two-dimensional position coordinates (X+ 1:Y-1). Finally, the first processor 320 selects the corresponding action 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 activate the actioner 330. And the motion control code belongs to the same matrix data as the two-dimensional position coordinates (X+1:Y-1). It is also worth mentioning that the two-dimensional matrix data can be larger matrix data except for matrix data of 2×2 size, for example: 3×3 or 4×4. A larger and multi-order matrix data is transmitted through the wireless transmitter 210, which can further subdivide the corresponding multiple levels with the intensity of the radio wave, and the position of the wireless receiver 310 can be accurately calculated by the first processor 320. The installation density of the wireless transmitter 210 can also be reduced, thereby greatly reducing the system installation cost. Moreover, the mobile device 300 can receive a large number of sampled radio wave intensity values to accurately calculate the mobile device to be finer and more precise. The coordinates, in turn, allow the effective coverage of the wireless base station 200a to separate more areas.

Comparing FIGS. 4 and 5, the mobile device 300 of FIG. 4 receives the location identification codes p1 to p4 and the operation control code from the radio base stations 200a, 200b, 200c, and 200d, and the mobile device 300 of FIG. Then, the two-dimensional coordinate data (X, Y), (X+1, Y), (X, Y-1), (X-1, Y) from the wireless base stations 200a, 200b, 200c, 200d, and 200e are received. , (X, Y+1) and the corresponding two-dimensional matrix data. Whether the radio wave received by the mobile device 300 is a position identification code with an action control code, or a two-dimensional coordinate data with a two-dimensional matrix data, the mobile device 300 located at a specific location can be controlled regionally, not only for the activity. Planners can bring convenience and the audience can be more integrated into the performer's performance situation.
