又，當該鑰匙結構10置入該外部通道23並傳送該鑰匙編號至該鎖具結構20後，該鎖具結構20之鎖具處理部211係會產生一傳輸協定資料並發送至該鑰匙結構10。Moreover, when the key structure 10 is placed in the external passage 23 and the key number is transmitted to the lock structure 20, the lock processing unit 211 of the lock structure 20 generates a transmission agreement data and transmits it to the key structure 10.
藉此，當該鑰匙結構10置入該外部通道23後，該第一鎖具資料傳輸部231與該鑰匙資料傳輸部11係相互傳輸該開鎖資料，並經由該鑰匙處理部121及該鎖具處理部221進行分析比對，且該鑰匙結構10與該鎖具結構20之開鎖資料比對符合時，該鑰匙結構10及該鎖具結構20係先進行該開鎖資料之同步修改，並在修改完成後控制該鎖具25進行開鎖之動作。Therefore, after the key structure 10 is placed in the external passage 23, the first lock data transmission unit 231 and the key data transmission unit 11 mutually transmit the unlocking data, and the key processing unit 121 and the lock processing unit are passed through the key processing unit 121 and the lock processing unit.

如第五圖及第六圖所示，其係分為該鑰匙結構10及該鎖具結構20之結構關係示意圖；其中，該鑰匙控制部12及該鎖具控制部22皆使用微處理器HT66F50；該鑰匙訊號轉換電路13及鎖具訊號轉換電路26皆為數位轉類比電路；而該狀態顯示部22，則可為一般之光源警示器(如LED)或蜂鳴器。As shown in FIG. 5 and FIG. 6 , it is a schematic diagram of the structure of the key structure 10 and the lock structure 20; wherein the key control unit 12 and the lock control unit 22 both use a microprocessor HT66F50; The key signal conversion circuit 13 and the lock signal conversion circuit 26 are all digital to analog circuits; and the status display portion 22 can be a general light source warning device (such as an LED) or a buzzer.
在資料的發送上，本發明係使用自行設計的一線傳輸協定(1-wire protocol)，其規則如下：傳輸開始時，由發送端發送一個資訊，告知接收端資料開始傳輸，並在資料傳輸結束 後，發送另一個資訊告知資料已傳輸結束。In the transmission of data, the present invention uses a self-designed first-line protocol (1-wire protocol), the rules are as follows: when the transmission starts, the sender sends a message to inform the receiving end that the data begins to be transmitted, and at the end of the data transmission. After that, another message is sent to inform that the data has been transferred.
關於該開鎖資料之各項資料功能，係如第一表所述；該鑰匙結構10之開鎖資料總長度為8bytes，該鎖具結構20之開鎖資料總長度為9 bytes(當然，除了本實施例所列的資料長度外，在實務上，其長度係可依所需進行調整，當其總長度愈大時其複雜度就愈高)，其中，該鎖具編號、該鑰匙編號、該傳輸協定資料、鑰匙權限之長度為1Byte，而開鎖密碼為6Bytes。The data function of the unlocking data is as described in the first table; the total length of the unlocking data of the key structure 10 is 8 bytes, and the total length of the unlocking data of the lock structure 20 is 9 bytes (except, of course, in this embodiment) In addition to the data length of the column, in practice, the length can be adjusted as needed, and the greater the total length, the higher the complexity), wherein the lock number, the key number, the transmission agreement data, The key permission has a length of 1 Byte and the unlock password is 6 Bytes.
傳輸協定資料是鎖具結構於每次開鎖，檢測到鑰匙時動態產生。The transmission agreement data is that the lock structure is dynamically generated each time the lock is detected and the key is detected.
如第七圖所示，其係本發明之傳輸協定資料之實施例，其傳輸過程係包含：[A]頭碼：發送端告知接收端有一筆資料開始傳輸，使接 收端對齊取樣時間；[B]資料碼：即發送端傳輸至接收端的資料內容；[C]尾碼：在資料內容傳輸完後，有一個低態持續一時間，告知接收端資料已傳輸完畢。As shown in the seventh figure, which is an embodiment of the transmission protocol data of the present invention, the transmission process includes: [A] header code: the transmitting end informs the receiving end that a data has been transmitted, and the connection is made. The sampling end time is the sampling time; [B] data code: the data content transmitted by the transmitting end to the receiving end; [C] the last code: after the data content is transmitted, there is a low state for one time, and the receiving end data has been transmitted. .
該傳輸協定資料包括傳輸時間及傳輸格式，在編號資料傳輸後，由該鎖具結構20提供給該鑰匙結構10，該鑰匙結構10與該鎖具結構20依據此傳輸協定資料進行開鎖密碼傳輸，且每次開鎖的傳輸協定資料皆不相同(也就是該鎖具處理部211每次產生的傳輸協定資料都會不同)。The transmission agreement data includes a transmission time and a transmission format. After the number data is transmitted, the key structure 10 is provided by the lock structure 20, and the key structure 10 and the lock structure 20 perform an unlock password transmission according to the transmission agreement data, and each The transmission protocol data of the unlocking is different (that is, the transmission protocol data generated by the lock processing unit 211 is different each time).
假設該鎖具結構20所傳送之傳輸協定資料為10100111(bit7~bit0)，關於該傳輸時間，第一筆資料使用傳輸協定資料中的最低三個bit決定(bit2 bit1 bit0，也就是111)，第二筆資料使用bit3 bit2 bit1(也就是011)，以此類推，故，第六比資料使用bit7 bit6 bit5...，每一筆使用的三個bit資料代表000~111b，數字愈大傳輸時間愈長，且每一筆之傳輸時間也不一定相同(如第二表所示)；第二表即為其傳送第N筆資料對應的使用傳輸時間bit編號，因開鎖密碼為6個byte資料，故只列6個。Assume that the transmission protocol data transmitted by the lock structure 20 is 10100111 (bit7~bit0). For the transmission time, the first data is determined by using the lowest three bits in the transmission protocol data (bit2 bit1 bit0, that is, 111), The second data uses bit3 bit2 bit1 (that is, 011), and so on. Therefore, the sixth ratio data uses bit7 bit6 bit5..., and the three bit data used for each pen represents 000~111b. The larger the number, the longer the transmission time. Long, and the transmission time of each pen is not necessarily the same (as shown in the second table); the second table is the transmission time bit number corresponding to the transmission of the Nth data, because the unlock password is 6 bytes of data, so Only 6 are listed.
資料傳輸及取樣必須有相同時間週期，資料才能正確的被接收解讀，而該鑰匙結構10與該鎖具結構20係利用傳輸協定資料做為依據，讓雙方通訊協定統一(如第八圖所示，其係為資料發送取樣時間圖)。The data transmission and sampling must have the same time period, the data can be correctly received and interpreted, and the key structure 10 and the lock structure 20 are based on the transmission agreement data, so that the communication agreement between the two parties is unified (as shown in the eighth figure, It is the sampling time chart of data transmission).
在傳輸格式方面，該鎖具結構20所傳送之傳輸協定資料為10100111(bit7~bit0)，第一筆資料以bit0決定，第二筆資料以bit1決定...以此類推，故，第六筆資料以bit5決定，對應的資料為0就使用類比資料傳輸，對應的資料為1就使用數位資料傳輸，對應的bit數如第三表所示；也就是說，第一筆、第二筆、第三筆及第六筆為數位傳輸(對應的資料為1)，而第四筆及第五筆則為類比傳輸(對應的資料為0)。In terms of the transmission format, the transmission protocol data transmitted by the lock structure 20 is 10100111 (bit7~bit0), the first data is determined by bit0, the second data is determined by bit1, and so on, so the sixth stroke The data is determined by bit5. If the corresponding data is 0, the analog data is transmitted. If the corresponding data is 1, the digital data is transmitted. The corresponding bit number is shown in the third table; that is, the first pen, the second pen, The third and sixth pens are digitally transmitted (the corresponding data is 1), while the fourth and fifth pens are analogous (the corresponding data is 0).
關於該數位資料傳輸，其傳輸方式係使用數位的0與1準位，一組資料傳輸從最高位元開始傳輸，在發送端發送頭碼後，將資料碼用串列方式傳輸出去，由接收端利用與發送端傳輸時間相同的取樣時間做資料接收；如第九A圖所示，其係為數位資料傳輸時序圖，若要將資料69H數值做傳輸，資料碼為 01101001b，夾在頭碼與尾碼之間。Regarding the digital data transmission, the transmission mode uses the digits of 0 and 1 level, a group of data transmission starts from the highest bit, and after the sender sends the header code, the data code is transmitted in tandem, and is received. The terminal uses the same sampling time as the transmission time of the transmitting end to receive data; as shown in Figure IX, it is a digital data transmission timing diagram. If the data 69H value is to be transmitted, the data code is 01101001b, sandwiched between the header code and the last code.
在該類比資料傳輸方面，資料碼每一Byte分四次類比方式傳送，將資料碼分四段，每一段用類比電壓方式做輸出，由接收端使用類比轉數位功能，組成一筆資料碼，這裡將資料碼分作四段電壓值，每一段代表2bits資料，(第九B圖為類比資料傳輸時序圖，資料碼為01110010b)。In the analog data transmission, the data code is transmitted in four analogous ways per Byte, and the data code is divided into four segments, each segment is outputted by analog voltage method, and the receiving end uses the analog-to-digital function to form a data code. The data code is divided into four segments of voltage values, each segment representing 2 bits of data, (the ninth B is the analog data transmission timing diagram, the data code is 01110010b).

更詳細說，關於該鑰匙結構10與該鎖具結構20之開鎖程序，請參閱第十一圖之流程說明。In more detail, regarding the unlocking procedure of the key structure 10 and the lock structure 20, please refer to the flow description of the eleventh figure.
先將該鑰匙結構10***該外部通道23中，使該鑰匙電源接腳14與該鎖具電源接腳232接觸，進而使該鎖具結構20供電至該鑰匙結構10，並傳送該鑰匙編號至該鎖具結構20之鎖具控制部21；在該鑰匙編號之傳輸過程中，即包括頭碼、資料碼、尾碼，該頭碼係具有告知資料傳輸開始，該資料碼具有鑰匙編號(將該鑰匙結構10的編號告知該鎖具結構20，藉由此編號取出開鎖密碼)。The key structure 10 is first inserted into the external passage 23, and the key power pin 14 is brought into contact with the lock power pin 232, thereby supplying the lock structure 20 to the key structure 10, and transmitting the key number to the lock. The lock control unit 21 of the structure 20; in the transmission process of the key number, that is, including a header code, a data code, and a tail code, the header code has a notification data transmission start, and the data code has a key number (the key structure 10 is The number of the lock informs the lock structure 20, by which the unlock code is removed.
該鎖具結構20在收到該鑰匙結構10所發送的鑰匙編號後，係會搜尋該鎖具記憶體212內是否有對應的鑰匙編號；若該鎖具記憶體212內有對應的鑰匙編號，則該鎖具結構20係會發送該鎖具編號及傳輸協定資料給該鑰匙結構10，且該狀態顯示部22顯示為藍燈(代表該鑰匙結構10***且該鑰匙編號符合)；而若該鎖具記憶體212內無對應的鑰匙編號，則該鎖具結構20顯示紅燈4秒後進入省電模式，該鑰匙結構10在沒有收到該鎖具結構20發送之鎖具編號的情況下，係會進入 待機狀態等待下次通電。After receiving the key number sent by the key structure 10, the lock structure 20 searches for the corresponding key number in the lock memory 212; if the lock memory 212 has a corresponding key number, the lock The structure 20 transmits the lock number and the transfer protocol data to the key structure 10, and the status display portion 22 displays a blue light (indicating that the key structure 10 is inserted and the key number is matched); and if the lock memory 212 is inside If there is no corresponding key number, the lock structure 20 enters the power saving mode after displaying the red light for 4 seconds, and the key structure 10 enters without receiving the lock number sent by the lock structure 20. The standby state waits for the next power-on.
該鑰匙結構10在收到該鎖具結構20發送之鎖具編號後，係會搜尋該鑰匙記憶體122內是否有對應的鎖具編號；若該鑰匙記憶體122內有對應的鎖具編號，則進入解密程序；若該鑰匙記憶體122內無對應的鎖具編號，則進入待機，等待下次該鑰匙結構10重新***。After receiving the lock number sent by the lock structure 20, the key structure 10 searches for the corresponding lock number in the key memory 122; if the key memory 122 has a corresponding lock number, the decryption program is entered. If there is no corresponding lock number in the key memory 122, it will enter standby and wait for the key structure 10 to be reinserted next time.
關於該解密程序，係當該鎖具結構20發送完該鎖具編號給該鑰匙結構10後，該鑰匙結構10依該傳輸協定資料設定之傳輸時間及傳輸方式將開鎖密碼發送至該鎖具結構20。With respect to the decryption program, after the lock structure 20 sends the lock number to the key structure 10, the key structure 10 transmits the unlock code to the lock structure 20 according to the transmission time and transmission mode set by the transmission protocol data.
該鎖具結構20接收到該鑰匙結構10發送的開鎖密碼後，係會先比對與該鎖具記憶體212內的開鎖密碼是否相同；若開鎖密碼相同則進入密碼修改程序；若開鎖密碼不同，則該狀態顯示部22顯示紅燈4秒後進入省電模式。After receiving the unlock password sent by the key structure 10, the lock structure 20 first compares with the unlock password in the lock memory 212; if the unlock password is the same, the password modification program is entered; if the unlock password is different, The state display unit 22 enters the power saving mode after displaying the red light for 4 seconds.
修改密碼程序必須雙方資料吻合才會進行修改密碼，首先由該鎖具結構20對該鑰匙結構10提供一正確開鎖訊號(假設以數位傳輸方式傳輸正確開鎖訊號資料10101010b)，該鑰匙結構10接收後與該鎖具結構20同步進行開鎖密碼之修改；開鎖密碼由一開始該鎖具結構20提供至該鑰匙結構10之傳輸協定資料作為依據，六組密碼會修改其中的兩組。例如：第一組及第二組密碼由傳輸協定資料最低位元bit.0作為判斷，若為0則修改第一組密碼，若為1則修改第二組密碼；再由傳輸協定資料的bit.2及bit.1作為判斷，若為00時修改第三組密碼，若為01時修改第四組密碼，若為10時修改第五組密碼，若為11時修改第六組密碼，因此六組密碼會修改其中兩組，而修改方式係將原本資料(開鎖密碼)加上傳輸協定資料1byte數值後儲存回該鎖具記憶體(關於傳輸協定資料修改密碼對照，請參閱第四表)。The password modification program must match the data of both parties to modify the password. First, the lock structure 20 provides a correct unlock signal to the key structure 10 (assuming that the correct unlock signal data 10101010b is transmitted by digital transmission), and the key structure 10 is received and The lock structure 20 synchronizes the modification of the unlock password; the unlock password is based on the transmission agreement data provided by the lock structure 20 to the key structure 10, and the six groups of passwords modify two of the groups. For example, the first group and the second group of passwords are judged by the lowest bit bit.0 of the transmission agreement data. If it is 0, the first group of passwords is modified. If it is 1, the second group of passwords is modified; .2 and bit.1 as a judgment, if it is 00, modify the third group of passwords, if it is 01, modify the fourth group of passwords, if it is 10, modify the fifth group of passwords, if it is 11, modify the sixth group of passwords, so The six groups of passwords will modify two groups, and the modification method is to store the original data (unlocking password) with the transfer protocol data 1 byte value and store it back to the lock memory (for the transmission agreement data modification password comparison, please refer to the fourth table).
舉例來說，假設傳輸協定資料末三碼為011b；則代表修改第二筆及第四筆密碼。For example, suppose the last three codes of the transmission agreement data are 011b; it means that the second and fourth passwords are modified.
由於每一筆資料為1byte長度，因此數值超過255(FFH)會歸零，如原數值為180，傳輸協定資料為100，那加後的數值會變成180+100-256=24，數字不會無限的變大。Since each data is 1 byte in length, the value exceeds 255 (FFH) and will be reset to zero. If the original value is 180 and the transfer protocol data is 100, the added value will become 180+100-256=24, and the number will not be unlimited. Become bigger.
在密碼修改完成後，該鎖具控制部21即控制該開鎖電路251而使該鎖具25進行開鎖之動作(該狀態顯示部22顯示為綠燈)。After the password modification is completed, the lock control unit 21 controls the unlock circuit 251 to unlock the lock 25 (the status display unit 22 is displayed in a green light).
當然，本發明也可設有兩個狀態顯示部22，分別為光源警示器及蜂鳴器；光源警示器利用燈光顏色變化，在視覺上提醒使用者目前之開鎖情形，而蜂鳴器是在聽覺方面的警告作 用，如***鑰匙3次未能開鎖，第4次以後的鑰匙***動作皆會響起，跟著光源警示器4秒後進入省電模式，或者鑰匙開鎖後未拔除超過6秒，會響起直到鑰匙拔除。Of course, the present invention can also be provided with two status display portions 22, which are respectively a light source warning device and a buzzer; the light source warning device visually reminds the user of the current unlocking situation by using the color change of the light, and the buzzer is in the Hearing warning If the key is unlocked 3 times, the key insertion operation will be sounded after the 4th time. After 4 seconds, the light source warning device will enter the power saving mode, or the key will not be removed for more than 6 seconds after being unlocked, and will sound until the key is removed. .
由以上說明可知，該鑰匙結構10也可設有多組開鎖資料，以對應不同鎖具結構20之開鎖資料(依該鑰匙結構10及該鎖具結構20的編號互傳，即可從該鑰匙結構10多組開鎖資料中找出相符的一組而進行開鎖程序)；也就是說，只需帶一把具有多組開鎖資料的鑰匙結構10，即可開啟不同之鎖具結構20(例如：同時設有與住家、公司之鎖具結構20相同之開鎖資料)，可同時達到體積小重量輕之優點。It can be seen from the above description that the key structure 10 can also be provided with a plurality of sets of unlocking materials to correspond to the unlocking materials of the different lock structures 20 (the key structure 10 and the structure of the lock structure 20 can be mutually transmitted, and the key structure 10 can be obtained from the key structure 10 A plurality of sets of unlocking data are found in a matching group to perform an unlocking process; that is, a key structure 10 having a plurality of sets of unlocking data can be opened to open different lock structures 20 (for example, at the same time The same unlocking information as the lock structure 20 of the home and the company can simultaneously achieve the advantages of small size and light weight.

關於本發明在使用最高權限鑰匙完成開鎖後之權限設定流程關係圖，請參閱第十二圖所示。Please refer to the twelfth figure for the relationship setting process of the present invention after the unlocking is completed using the highest authority key.
綜上所述，本發明之優點及功效可歸納為：In summary, the advantages and effects of the present invention can be summarized as follows:
[1]保密性高。市面上也有一些結構型式較為複雜的鎖與鑰匙，但都只是在型式上進行變化，只要能了開鎖的結構，還是可以將鎖打開，其安全性較低；而本發明之開鎖程序需經由該鑰匙結構10與該鎖具結構20之反覆溝通確認，才可達到開鎖，並自動進行該開鎖資料之修改，故，具有保密性高之優點。[1] High confidentiality. There are also some locks and keys with relatively complicated structure in the market, but they all change only in type. As long as the unlocking structure can be opened, the lock can be opened, and the safety is low; and the unlocking program of the present invention needs to pass through the The key structure 10 and the lock structure 20 are repeatedly communicated and confirmed, so that the unlocking can be achieved, and the unlocking data is automatically modified, so that the confidentiality is high.
[2]具權限設定功能。在房屋仲介進行買賣期間，仲介與賣家通常都會擁有門鎖鑰匙，當成功轉售於新買家後，新買家並無法確定賣家與仲介是否將所有鑰匙交還，故，仍有安全上之疑慮；而本發明可利用其權限設定，將最高權限以外的鑰匙權限刪除而無法開鎖，更進一步提高其安全性。[2] With permission setting function. During the sale of the house agent, the agent and the seller usually have the door lock key. When the new buyer is successfully resold, the new buyer is not sure whether the seller and the agent will return all the keys. Therefore, there are still security concerns. The invention can use its authority setting to delete the key authority except the highest authority and cannot unlock the key, thereby further improving the security.
[3]體積小重量輕。一般開啟不同的門鎖則需攜帶不同的鑰匙，常使得使用者需要攜帶大把鑰匙出門，在攜帶上相當不便；而本發明只需對該鑰匙結構10設定多組開鎖資料，即可開啟不同之鎖具結構20，達到體積小重量輕之優點。[3] Small size and light weight. Generally, different keys are required to carry different keys, which often makes it necessary for the user to carry a large number of keys to go out, which is quite inconvenient to carry. However, the present invention only needs to set multiple sets of unlocking data for the key structure 10 to open different The lock structure 20 achieves the advantages of small volume and light weight.
[4]價格低。本發明在結構設計上，其成本可比市面上之晶片鎖低上許多，故，具有價格低之優點。[4] The price is low. The structure of the invention has a lower cost than the wafer lock on the market, so it has the advantage of low price.
[5]不需裝設電池。本發明之鑰匙結構10在***該鎖具結構20後，係利用該鑰匙電源接腳14與該鎖具電源接腳232之接觸而得到所需之電源，故，不需裝設電池。[5] There is no need to install a battery. After the key structure 10 of the present invention is inserted into the lock structure 20, the key power supply pin 14 is brought into contact with the lock power supply pin 232 to obtain the required power supply, so that no battery needs to be installed.
以上僅是藉由較佳實施例詳細說明本發明，對於該實施例所做的任何簡單修改與變化，皆不脫離本發明之精神與範圍。The present invention has been described in detail with reference to the preferred embodiments of the present invention, without departing from the spirit and scope of the invention.
