Description of the invention (1) Background of the invention (please read the notes on the back before filling out this page) The present invention is a method for confirming the communication range In particular, it refers to a method for confirming the communication range for confirming whether two wireless communication devices are within the communication range so that they can communicate with each other. Related Background Art This type of system is known to allow multiple wireless communication devices to communicate simultaneously using the same frequency. Fig. 6 is an illustration of this communication system, in which different identification codes are assigned to different radio stations. For example, in the system shown in FIG. 6, "〇1 〇" is assigned to Radio A as a digital code, * 0 2 0 " is assigned to Radio B as a digital code, ~ 0 1 〇〃 is assigned to C wireless station as a digital code, each code is regarded as an identification code. Printed by a member of the Intellectual Property Bureau of the Ministry of Economic Affairs, Consumer Cooperative. In this example, Radio A uses f frequency to perform transmission to Radio B1 and Radio B performs reception at the same frequency. The identification codes of the stations are different from each other, so this transmission cannot be completed with each other = However | Since radio stations A and C are assigned the same identification code " 0 1 0 〃, when both are within the communication range, this Two radio stations A and C can communicate with each other. In this example, as a method for confirming that Radio A and Radio C are placed within the communication range of each other, the identification code in the digital code and the paper size are applicable to the Chinese standard < CNS) A4 specification.

Description of the invention (2) Phase detected 'When this identification code is detected, receive The end will notify the corresponding end and the receiving end is within the communication range. When this identification code is not detected, the receiving end will notify the corresponding end that the receiving end is not within the communication range. The confirmation of the communication range can be performed by displaying a notification 'on the display of the radiotelephone or by generating a predetermined sound signal. Fig. 7 and Fig. 8 are control flowcharts showing this conventional method for confirming the communication range. Now 1 assumes that the first radio station and the second radio station can complete transmission and reception on the same frequency, and are assigned the same identification code. Generally, a 'digital identification code is converted into a dual tone multi-frequency (D T M F) signal', and this signal is added to a transmission frequency used for transmission. When the first radio station and the second radio station perform communication range confirmation, and the two ends can communicate, first, the communication range check function provided to the two radio stations is turned on (step 1 〇1 Α and 1 0 1 Β ). Next, the timer for the communication range check installed on the first radio station will be set to a preset time such as 60 seconds (step 1 02). In addition, when the time set by the fixed timer expires, then a predetermined frequency will be set, and the station's own identification code will be converted into a dual-tone multi-frequency signal and added to the predetermined transmission frequency. f, the combined signal is transmitted to the second radio station (step 1 ◦ 3). Because the second radio station has already entered the waiting state at this stage, it will detect whether the identification code in the frequency f transmitted by the first wireless station matches its own identification code, and whether the reception is feasible (Step 1 0 4). When the detection result at the receiving end is feasible, this paper size is applicable to the National Standard (CNS) A4 specification (210 X 297 mm) -5- ------------ install i!

Description of the invention (3) The symbol w that symbolizes successful detection ☆ " will It is displayed on the display, and the timer used to detect its own communication range will be set to 60 seconds (step 10 5). On the other hand, when the received detection result is not feasible, > η-number ν ☆ 〃 will not appear, and the timer will be set to 60 seconds (step 10 6). When the time set by the fixed timer reaches 60 seconds, the second wireless gastric station adds its own identification code to the transmission frequency f as a transmission to the first Jianwuxinquan station (step 107). The first radio station will determine if it & detected this signal (step 108). When the detection result at the receiving end is feasible, the symbol "☆" will be displayed like the first radio station, and the timer will be reset to 60 seconds (step, step 10 9). When the detection result at the receiving end is not feasible, the symbol * will not be displayed, and the timer will be reset to 60 seconds (step 1 1 0). In this way, in the case where the two radio stations' symbol ☆ 〃 is illuminated at steps 105 and 10, the two radio stations are within communication range and can talk, so that The scheduled conversation is completed. When a predetermined time has elapsed and an attempt to check the communication range is again made, the same operation as in step 103 is completed in the first radio station in the step. In the case where the symbol `` ☆ 〃 '' has been displayed on the second radio station, and when the access change has been detected (step 1 1 2), the symbol `` ☆ 〃 will continue to appear and the timer will be set to 6 0 seconds. On the other hand, when the detection result is not feasible, the symbol # will be turned off | and a beep will sound so that the second radio station can know that the first radio station is already in the communication range 1 III ---- ----- ^ --------- Line 靖 Jing first read the back of the book; i will fill in this page for the matters of interest. 智慧 The paper printed by the Consumers' Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs applies Chinese national standards.

Description of the invention (4) Outside the scope (step 1 1 4). After that, the timer will be set to 60 seconds (step 1 15). After the time set by the timer expires, the dual-tone multi-frequency signal is added to the transmission frequency f and the combined signal will be transmitted to the first one. Radio station (step 1 1 6). As the processing steps for detecting the reception of the first radio station 1 1 7 to 1 2 0 are the same as the steps of the second radio station 1 1 2 to 1 1 5 3 Therefore, the method of the traditional wireless communication device to confirm the communication range is to It is performed by converting a digital identification code into a dual-tone multi-frequency signal and a fixed timer for confirmation and a fixed time determined in advance. Therefore, in the traditional method of confirming the communication range, the time interval from the completion of the first inspection to the start of subsequent inspections is always fixed at a certain amount of time. Therefore, when multiple radio stations have enabled the function of checking the communication range at the same time point, the time interval of all radio stations is fixed, which causes a problem that the perturbation when the identification code is received will not allow identification. The correct identification of the code results in that although the parties are within the communication range, these devices will be considered outside the communication range. In addition, because it must use a digital identification code to convert it to a dual-tone multi-frequency signal, and add it to the transmission frequency used for transmission, it will cause a problem-it must use a circuit that converts the digital identification code to a dual-tone multi-frequency signal, so that The device is expensive.

Description of the invention (7) Detailed description of the preferred embodiment The detailed description of the preferred embodiment of the invention will be described with reference to the drawings as follows 3 'In the present invention, instead of using the D signal based on the conventional method, the CTCSS frequency is adopted as the identification code. The C T C S S frequency is also called T S and is assigned to 38 waves between 67 Hz and 250 3 Hz according to world standards. Figure 4 shows the CTCSS number and its corresponding frequency, which can be specified in the C T C S S setting mode. The C T C S S frequency, used when the audio is transmitted by radio wave transmission and transmitted by a fixed counterpart, overlaps the transmission frequency used for transmission. Because the receiver will use a high-pass or band-pass filter to interrupt the C TC S S frequency to take out the audio signal, the CTCSS frequency will not affect the transmission. Fig. 5 shows a configuration diagram of a communication system used in the communication range confirming method of the present invention. Different from the conventional communication system shown in FIG. 6, the audio represented by the C T C S S number is used as a discrimination code and is individually assigned to the A radio station by C 1. That is, the C T C S S number 无线电 1 is assigned to the A radio station 'number 値 15 is assigned to the B radio station, and at the same time, the number i is assigned to the C radio station as a discrimination code. Therefore, Radio A and Radio C can communicate with each other by using the same transmission frequency; however, because the CTC SS numbers assigned to A 1 and B 1 are different, 'TS A and Radio B will not be turned on. The stations cannot communicate with each other. Since this ------------- 1! 11 Orders · 1!

Description of the invention (8) c TCSS frequency is reserved as a discrimination code, so it is not necessary to convert the digital code into The analog code eliminates the need for a circuit for conversion and the cost of the device becomes low. In addition, in the confirmation method of the present invention, a random timer is used as an interval timer for determining the communication range, so that the problem that the intervals correspond to each other when multiple radio stations try to determine the communication range at the same time point can also be solved; Can solve the problem of radio wave interference when the radio receiving code does not accept the correct detection code. Incidentally, since the method for confirming the communication range of the present invention has such characteristics, it can be particularly called the c RDS (Communication Range Detection System) function. FIG. 1 is a time flow chart 1 as an example in the present invention. The proposed method for confirming communication standards. Here is how to confirm the communication range between the first radio station and the second radio station. At time A 0, the communication range detection system function of the first radio station is set to "ON". On the other hand, it is assumed that the communication range detection system function of the second radio station is also set to "on" at a predetermined time. After the communication range detection system function is turned on, the first radio station sets the Built-in interval timer to check automatically and set a predetermined time. In the present invention, the interval timer is set as a random timer, and for example, a predetermined time is automatically set randomly from 1 to 30 seconds, and at time A 1 when a randomly set time T 1 1 After a while, the first radio station transmits a transmission frequency f that carries the CTCSS signal assigned to it to the second radio station. In this example, the second radio station can receive the paper standard applicable to China.

Description of the invention (9) The transmission frequency f of the CTCSS frequency can be understood as' the first radio station is within a communication range 3 [Table 1] here In the environment, the antenna symbol () is not shown on the L c D display. In addition, at the same time, as at the first radio station, the built-in self-check interval timer is randomly set to a preset At a certain time, at this stage (time B 2), when a randomly set time T 2 1 has passed, the first radio station transmits a transmission frequency f carrying the CT CSS signal assigned to itself to the first Radio station. When the first radio station can detect the transmission frequency f from the second radio station, including the CTCSS frequency, at time A 2, the antenna symbol will be displayed on its own LCD display and used as a check. The interval timer of subsequent cycles will be randomly set at time T 1 2. In addition, in the phase of time A 3, when the time set in this period T 1 2 is over, transmission 1 of the signal carrying CTCSS will be transmitted to On the second radio station [Result 1]. However | When a predetermined time has elapsed, in the case where the confirmation signal cannot be received from the second radio station, the second radio station is considered to be in a communication range The antenna symbol shown outside on the LCD screen will be canceled (that is, the antenna symbol will disappear). In addition, the confirmation signal will be retransmitted to the second radio station (result 2), however, in this example, The interval timer setting time becomes a longer fixed predetermined time or a random time, for example, one minute or 50 to 70 seconds. In this way, due to the corresponding end outside the communication range, you can — — — — — — 111 — — i I-— — — I — — — {Please read the notes on the back before filling out this page) This paper size applies to China National Standard (CNS) A4 (210 X 297 mm) -12-A7 462168 ____B7___ V. Description of the invention (10) A random timer can be used to send out a confirmation signal frequently within a short interval, and it is detected whether the corresponding end is located Possibility of communication range becomes lower, so the consumption of battery power related to transmitting the confirmation signal will be reduced. The operation of the second radio station depends on whether the first radio station is willing to receive the confirmation signal, and in this example, According to the result 1, it is confirmed that the signal has been transmitted from the first radio station. At time B 3, the antenna symbol is continuously displayed, and the random timer as the interval timer is set at the time T 2 2 which is randomly determined in advance. However, according to the result 2 above, in the example of confirming that the signal has not entered, because the radio reception cannot be detected, the other end is considered to be outside the communication range, and the display of the antenna symbol will disappear. A “beep” sound informs the user that the corresponding end line is out of communication range. The following steps are the same steps except that the communication range detection system is turned off = Figures 2 and 3 show a flow chart on a time chart. Figure 1 has been described in Figure 1, which itself is as described in Figures 7 and 8. It is known that the traditional flowchart has the same work flow, that is, steps 2 01 to 2 2 0 correspond to steps 1 0 1 to 1 2 0, respectively. The present invention is different from the traditional workflow in that the interval timer used to check the communication range is a random timer and the identification code is a C T C S S signal. Furthermore, another difference of the present invention is that the timer will be set again without the confirmation signal from the corresponding radio station being detected.

The setting time of the fixed timer or the random timer with this longer time is set to be longer than the maximum setting time of the random timer at the beginning, and for the maximum setting time of the random timer of 30 seconds, It is considered most appropriate at around 1 minute. In the case that no acknowledgment signal from the corresponding radio station is detected, even afterwards, in a random time shorter than the time set by a fixed timer or a random timer with a longer time, return A confirmation signal, the possibility that the corresponding end is located within the communication range is reduced. 1 Due to frequent inspection operations, lower battery consumption is required. So far, according to the detailed description of the example, the random timer has been used as an interval timer for confirming the communication range to check at a pre-confirmed random time so that multiple repeaters will not be checked repeatedly, and The radio reception code may be interrupted. In addition, in a communication range, the interval timer will be continuously set to a random timer with a relatively short time. However, in this example, if the corresponding end is outside the communication range, a fixed timer or A longer random timer will be turned on, which will reduce battery consumption = Furthermore, as a discriminator 'c TCSS frequency is used so that the identifier does not need to be converted to an analog signal' and can also be reduced Manufacturing cost of the device.
