图2描述了教师控制面板113的外观图,该教师控制面板113又可分为三部分。 2 depicts an external view of the teacher control panel 113, the teacher has control panel 113 can be divided into three parts. 第一部分为声频控制单元201,该单元控制声频资讯的操作,诸如声频输入,麦克风(Microphone)与喇叭(Speaker)的音量控制;第二部分为学生通讯单元202,该单元显示目前的学生状态,例如:当一学生向教师提出问题时,该学生所占据的学生工作站,与该学生通讯单元上相对应的灯号即会亮起,用以提示教师该学生的所在;第三部分为教学控制单元203,该单元操控所有与教学相关的动作,诸如向所有学生广播、传送声频与视频资讯、以及加入学生的对话等等的操作。 The first part of the audio control unit 201, the operation information of the unit control audio, such as an audio input, a microphone (the Microphone) and speaker (Speaker) volume control; the second part student communication unit 202, the unit displays the current student status, for example: when a student to ask questions to the teacher, the student workstations occupied by students, and the students' communication unit corresponding lights will light up to prompt the teacher where the students; the third part is teaching control unit 203, the control unit associated with the teaching of all the action, such as a broadcast to all students, transmit audio and video information, and join student dialogue, etc. operations.

有一点必须注意的是,教师工作站11与学生工作站12的基本架构相同,两者间唯一的差别在于控制面板的不同。 It must be noted that the teacher workstation 11 has the same basic architecture student workstation 12, the only difference is that between the two different control panel. 学生控制盒123仅包含教师控制面板113中的声频控制单元201,用以控制其工作站的声频资讯操控(诸如耳机音量的调整等等);以及一呼叫按钮,用以向教师提出问题。 Student control box 123 includes only the sound of the control panel 113 in the teacher frequency control unit 201 to control the audio information control station (such as a headphone volume adjustment, etc.); and a call button for questions to the teacher. 所以当教师欲将教师工作站移至其他工作站时,工作站的控制面板亦须同时变更。 So when the teacher of teachers wishing to move to another workstation workstation, the workstation must also change the control panel at the same time.

本发明所提出的多媒体网络教学系统,其软件部分可分为两部分;教师部分与学生部分。 Multimedia network teaching system proposed by the present invention, the software part can be divided into two parts; part of teachers and students section. 图3A、3B、4A、4B、5A、与5B描述了教师部分的主要软件程序(Procedure),图6A、6B、7A、7B、8A、8B、9A、与9B则描述了学生部分的主要软件程序。 FIGS. 3A, 3B, 4A, 4B, 5A, and 5B describe the main software program (Procedure) teachers portion, FIG. 6A, 6B, 7A, 7B, 8A, 8B, 9A, and 9B are described in the main software student portion program. 教师工作站必须同时执行教师与学生部分的软件程序,但学生工作站只需执行学生部分的程序即可。 Teacher workstation must perform the teachers and students part of a software program, but just a student workstation to execute part of the program students. 该区分提供上述教学系统在工作站角色交换上的弹性。 The elasticity of the teaching system to distinguish provided on the workstation role exchange. 例如一教师想要将其工作站移至某学生的旁边,他/她可于原先的教师工作站上卸下教师部分的软件程序,并于其想要的工作站上执行教师部分的程序即可(当然,教师控制面板与学生控制盒需要交换)。 Program execution on the part of teachers, for example, a teacher workstation to workstation you want to move next to a student, he / she can be a software program to remove the part of the teachers on the original teacher workstation, and it wants to (of course, teachers and students in the control panel control box needs to be exchanged).

图3A与3B对教师三作站的主要操作做一说明。 3A and 3B the operation of the main station for the teacher to make a three instructions. 其包含教师工作站的自我测试,检查是否有学生提出问题等步骤。 Which comprises a teacher workstation self-test to check whether there are steps students to ask questions and so on. 所有的动作开始于教师工作站的电源被打开之时(步骤301)。 All the power supply operation starting at the teacher workstation is turned on (step 301). 首先,该教师工作站初始化(Initialize)其内部暂存器(步骤302),接着执行自我测试的动作(步骤303)。 First, the teacher workstation initialization (the Initialize) which internal register (step 302), the operation of the self-test is then performed (step 303). 若于自我测试之时发生错误,或是有任何键(Key)于此时被按下(步骤305),该教学系统将发出哔声,或显示出一些错误讯息(步骤304)。 If an error occurs in the self-test, or have any key (Key) is depressed at this time (step 305), the teaching system beeps or displays some error message (step 304). 整个教学系统于是停止动作(步骤306)。 Thus the entire teaching system stop operation (step 306).

如果自我测试正常结束,该教学系统接着将检查是否有学生在线上,或是有学生向教师提出问题(经由标号B至步骤307),该动作可藉由测试一“有问题在线上(Question-on-line)”之布林(Boolean)型态标志(Flag)来完成。 If the self-test ends normally, the education system then checks to see if the students online, or have students ask questions to teachers (via label B to step 307), the action can be tested on by a "problematic online (Question- on-line) "the Breen (Boolean) type flag (flag) to complete. 若是该“有问题在线上”标志为真(True),表示有学生向教师发问,该教学系统将检测教师控制面板的缓冲区(Buffer)是否空着(Empty)(步骤308)。 If the "problem on the line" flag is true (True), represents the students to ask questions to teachers, the teaching system will detect buffer (Buffer) teacher control panel whether empty (Empty) (step 308). 若该缓冲区为空,表示传送动作是被允许的(步骤309);该教学系统首先设立一布林型态的“禁止(Prohibition)”标志,以阻止其它传输动作的发生。 If the buffer is empty, showing the transfer operation is allowed (step 309); the teaching system to establish a first type of Boolean "No (Prohibition)" flag, to prevent the occurrence of other transfer operation. 真实的传输动作才接着进行,将解答由教师工作站送至学生工作站中,该“有问题在线上”标志最后被重设为假(False)。 The real action was followed by transport, the answer from the teacher to the student workstations workstation, the "problem on the line" last flag is reset to false (False).

教师藉由按下教师控制面上的按键来回答学生的问题(步骤313)。 Teacher Teacher control by pressing the face buttons to answer a student's question (step 313). 若有任何键于此情况被按下,该按键的代表值将被读出,并设立布林型态的”按键被按下(Key-is-pressed)”标志为真(步骤315);该教学系统接着回头检查是否有其他的问题在线上(经由标号A至步骤307)。 If any key is pressed in this case, the representative key value is read out, and set patterns Brin "key is pressed (Key-is-pressed)" flag is true (step 315); the Teaching system then checks whether there are other back problems online (via a reference to step 307). 若没有任何按键被教师按下,该教学系统设立计时器(Timer)的时间为50毫秒(millisecond),用以等候教师的回答(步骤314)。 If no button is pressed teachers, the teaching system to set up a timer (the Timer) time of 50 milliseconds (millisecond), for the answer (step 314) to wait for the teacher. 整个教学系统接着回头检查是否有其他的问题在线上(经由标号A至步骤307)。 Whole teaching system then checks whether there are other back problems online (via A reference to step 307).

若是自我测试正常结束,而且没有任何问题于线上,该教学系统将检查“按键被按下”标志的状态(步骤310)。 If the self-test is completed normally, and no problems online, the system will check instruction "button is pressed" state of the flag (step 310). 若该标志为真,意即教师已回答学生的问题;当然,该教学系统必须先检查教师控制面板的缓冲区使否为空(步骤311),若该缓冲区为空,意即传输动作是被允许的。 If the flag is true, which means that teachers have to answer students' questions; of course, the education system must first check the teacher's control panel whether the buffer is empty (step 311), if the buffer is empty, which means the transfer operation is Allowed. 首先,该教学系统将设立“禁止”标志,以禁止其他传输动作的进行;真实的传送动作接着才进行,将解答由教师工作站传送至学生工作站,“有问题在线上”标志在传送结束后被设立为假。 First, the education system will be set up "prohibited" signs to prohibit transmission of other actions; real action then only be transferred, the transfer will be answered by the teacher to student workstations workstation, "There is a problem online" mark after the end of the transfer established as false. “按键被按下”标志随后亦被重设为假(步骤312)。 "Button is pressed" flag was also reset to false then (step 312). 否则,若该“有问题在线上”标志为假,教学系统将再检测教师是否按下其他按键(步骤313)。 Otherwise, if the "problematic online" flag is false, teachers teaching system detects whether Jiangzai press another button (step 313).

图4A与4B说明的多媒体传输器中断程序所执行的功能,其描述多媒体传输器中,接收与传送的操作情形。 FIG. 4A function program executed by multimedia transmission and 4B illustrate the interrupt, which describes a multimedia transmitter, receiver and transmission operating situations. 在该多媒体传输器运作后(步骤401),该多媒体传输器必须检查位于其缓冲区的资讯为将传出抑或接收者(步骤402),该步骤可经由测试布林型态的“传输中断”标志,以及“接收中断”标志来完成。 After (step 401) the operation of multimedia transmission device, transmission must check the multimedia information in its buffer for outgoing or whether the recipient (step 402), this step may "interrupt transmission" via the test patterns Brin logo, and "receive interrupt" flag to complete. 若是该缓冲区的资讯为将送出者(亦即上述的“传输中断”标志为真),该多媒体传输器先重设该“传输中断”标志为假(经由标号C至步骤403);要被传送出去的字元接着被送往PC的缓冲区中(步骤404);真实的传送过程中,该PC必须检查整个传送过程是否结束(步骤405)。 If the buffer information sent to the person (i.e., the aforementioned "interrupt transmission" flag is true), the multimedia transmitter to reset the "interrupt transmission" flag is false (via step 403 to reference numeral C); to be character is then transmitted out of PC buffer is sent (step 404); actual transmission process, the PC must be checked throughout the transfer process is ended (step 405). 若否,则上述的多媒体传输器将继续传输的动作(步骤404);若PC缓冲区的所有字元皆已送出,教师控制面板将设定一“允许传送”标志,告知教学系统整个PC缓冲区已空(步骤406)。 Operation (step 404) and if not, the above-described multimedia transmission will continue transmission; PC buffer if all the characters have switched out, the teacher control panel to set a "transmit permit" flag to inform the entire teaching system PC buffer area is empty (step 406). 该多媒体传输器接着返回,以等候下一个接收或传输的状态(经由标号D至步骤416)。 The multimedia transmitter then returns, a state waiting for the next received or transmitted (via reference numerals 416 to step D).

在控制面板缓冲区的资讯若为即将接收者(亦即上述的“接收中断”标志为真),意味着该控制面板接收一来自PC的命令(不论是来自教师或学生)。 Information in the control panel for the upcoming buffer if the recipient (ie the aforementioned "Receive Interrupt" flag is true), it means that the control panel receives a command from the PC (either from teachers or students). 该控制面板首先重设“接收中断”标志为假(试验407),接着解释该命令的意义;至此,所接收命令的意义已为该控制面板所了解(步骤408);接下来,该控制面板执行该命令指定的任务。 First, the control panel reset "Receive Interrupt" meaning flag is false (test 407), then interprets the command; At this point, the received command has understood the meaning (step 408) for the control panel; Next, the control panel execute the command specified task. 若该命令的值为0,则设定显示模式(步骤41O);若该命令的值为1,则设定哔声模式(步骤411);若该命令的值为2,则设定发问模式(步骤412);若该命令的值为3,则设定上线(On-line)模式(步骤413);若该命令之值为6,则设定下线(Off-line)模式(步骤414);最后,若该命令的值为10,则设定监督(Monitoring)模式(步骤415)。 If the command is 0, the display mode is set (step 41O); if the command value is 1, the beep mode is set (step 411); if the order is 2, the mode setting questions (step 412); if the order is 3, is set on the line (on-line) mode (step 413); if the value of the order of 6, is set offline (Off-line) mode (step 414 ); Finally, if the command value 10, supervision is set (Monitoring) mode (step 415). 在设定完该命令所指定的模式后、控制面板返回以等候下一个接收或传输要求的到来(步骤416)。 After setting the mode specified by the command, the control panel returns soon (step 416) to wait for a next reception or transmission requirements.

图5A与5B描述了一流程图,对哔声与LED状态中断程序(Beep andLEd-State Interrupt Procedure)的操作做一总结,当教师欲利用喇叭发出哔声,或是改变LED(发光二极管)的状态时需要呼叫该程序,而通常是有错误发生时才会执行此动作。 5A and 5B depict a flow chart of the operation state of the LED beep interrupt routine (Beep andLEd-State Interrupt Procedure) to make a summary, a teacher speaker beeps intended to use, or to change the LED (light emitting diode) the program needs to call upon state, but usually there are only performed this action when an error occurs. 每当该程序被呼叫时(步骤501),一布林型态的“时序中断”标志将被重设为假,一计数器将执行累加一的动作(步骤502)。 Each time (step 501) the program is called, a Boolean patterns "Interrupt Timing" false flag will be reset, a counter to perform an accumulation operation (step 502). 若是该计数器的值等于30,意即LED的闪烁状态将设定为30×50毫秒(步骤503);LED的状态亦将改变(即若原LED为暗,则变更为明;同样的,若LED原为明,则变更为暗)(步骤504);该LED的状态被显示之后(步骤506),计数器又重设回0(步骤506)。 If the value of the counter is equal to 30, meaning that the LED be set to a blinking state 30 × 50 ms (step 503); LED will also change state (i.e., if the original dark LED, is changed to the Ming; Similarly, if the LED original Ming, is changed to dark) (step 504); (step 506) state of the LED is displayed, and the counter reset to 0 (step 506).

若上述的计数器所储存的值不为30,则教学系统利用喇叭发出哔声。 If the above counter value is not stored 30, the teaching system beeps using the speaker. 在发出哔声之前,该教学系统将先检测一“哔声”标志,用以得知发出哔声是否被允许(经由标号E至步骤507)。 Before beeps, the teaching system to detect a "beep" flag to know whether a beep is allowed to emit (E via reference to step 507). 每当喇叭发出一哔声,一存有哗声次数的哔声计数器即自动减一(步骤508),喇叭一直发出哔声,直至该哗声计数器的值为0方停止(步骤509),同时亦终止该哔声与LED状态中断程序(步骤510),并返回至初始状态中(步骤511)。 Whenever the speaker emits a beep, a number of times there Wow sound beep counter is decremented by one (step 508), has the speaker beeps until the beep counter is 0 side is stopped (step 509), while this beep also terminates the interrupt routine and LED status (step 510), and returns to the initial state (step 511).
