Description
本發明係有關於一種數值控制裝置，特別是有關於一種具有可連接於數種受控制元件之主控制接口之數值控制裝置。 This invention relates to a numerical control device, and more particularly to a numerical control device having a main control interface connectable to several controlled components.
一般而言，工業用數值控制裝置常用以控制各種不同型態的受控制器，例如：車床、銑床及機械手臂等，然而，各種不同型態的受控制器之連接接口種類不盡相同，若一個數值控制裝置欲同時連接至不同種類的受控制器，則必須事先在數值控制裝置增設多個連接接口，或是額外加裝轉接器，但無論是以增設連接接口或是額外加裝轉接器，皆會造成成本的增加。 In general, industrial numerical control devices are commonly used to control various types of controllers, such as lathes, milling machines, and robotic arms. However, the types of connection interfaces of various types of controllers are not the same. If a numerical control device is to be connected to different types of controllers at the same time, it is necessary to add a plurality of connection interfaces in the numerical control device in advance, or to additionally install an adapter, but whether to add a connection interface or an additional installation The connector will cause an increase in cost.
更具體而言，當一數值控制裝置與多個通訊匯流排類型相同的受控制器連接時，其連接方式為數值控制裝置與一受控制器電性連接，此受控制器再與另一受控制器電性連接，依此方式串聯多個通訊匯流排類型相同的受控制器，其訊號傳遞方式則是數值控制裝置將所有受控制器所需的訊號先傳遞至第一個與數值控制裝置連接之受控制器，第一個受控制器擷取所需的資料後，第一個受控制器再將剩餘的訊號傳遞至第二個受控制器，依此方式傳遞至最後一個受控制器，然而，此方式僅可讓主控制器傳遞訊號至一個受控制器，或是讓一個受控制器傳遞訊號至主控制器，而無法同時讓主控制器傳遞訊號至受控制器且受控制器傳遞訊號至主控制器，如此一來，增加了整體訊號傳遞時間，也因此增加整體作業時間。 More specifically, when a numerical control device is connected to a controller of the same type of communication busbars, the connection mode is that the numerical control device is electrically connected to a controller, and the controller is connected to another controller. The controller is electrically connected, and in this way, a plurality of controllers of the same type of communication bus are connected in series, and the signal transmission mode is that the numerical control device transmits all the signals required by the controller to the first and the numerical controller. The connected controller is the first controller to retrieve the required data, and the first controller passes the remaining signals to the second controller, and then passes to the last controller. However, this method can only allow the main controller to transmit signals to a controller, or let a controller pass signals to the main controller, but not the main controller to transmit signals to the controller and the controller. Passing the signal to the main controller increases the overall signal transfer time and therefore the overall operating time.
另一方面，當一數值控制裝置增設多個可與不同種類受控制器連接之接口時，數值控制裝置所傳遞的訊號雖可個別傳遞於各個受控制器，但因數值控制裝置增設接口而增加成本， 且接口必須事先於數值控制裝置增設，如事後需額外增加連接受控制器的種類，則必須增設轉換器，亦增加整體成本。 On the other hand, when a numerical control device is provided with a plurality of interfaces that can be connected to different types of controllers, the signals transmitted by the numerical control device can be individually transmitted to the respective controllers, but are increased by adding interfaces to the numerical control devices. cost, And the interface must be added in advance to the numerical control device. If the type of the connected controller is to be added afterwards, the converter must be added, which also increases the overall cost.
為了解決先前技術所述之問題，本發明之主要目的在於提供一種數值控制裝置，其中，數值控制裝置之主控制接口可連接至各種不同種類的受控制接口，故主控制接口無需因受控制接口類型不同而需要額外增加主控制接口數量，因而降低成本。 In order to solve the problems described in the prior art, the main object of the present invention is to provide a numerical control device in which the main control interface of the numerical control device can be connected to various kinds of controlled interfaces, so that the main control interface does not need to be controlled interface. Different types require an additional number of primary control interfaces, thus reducing costs.
根據上述目的，本發明主要目的在於提供一種數值控制裝置，包括：一主控制器，其用以發送複數個第一控制訊號，每個第一控制訊號包含一串列資料；一暫存器，其電性連接於主控制器，暫存器具有複數個位址，暫存器接收第一控制訊號並輸出第一控制訊號，每一個第一控制訊號分別儲存於暫存器之部分位址；及一主控制接口，其具有複數連接埠，每一個連接埠具有複數個引腳，每一個連接埠之一端電性連接於暫存器，每一個連接埠之另一端分別電性連接至每一個連接埠所對應於一外部受控制元件之一受控制接口，主控制接口之連接埠分別接收暫存器所輸出之第一控制訊號之串列資料，且連接埠分別將所接收之串列資料輸出至連接埠所對應於受控制元件之受控制接口，且受控制接口可傳遞一第二控制訊號至主控制接口之連接埠，主控制端之連接埠傳遞第二控制訊號至暫存器之部分位址，暫存器將第二控制訊號傳遞至主控制器，主控制器藉由第一控制訊號與第二控制訊號控制受控制元件。 According to the above objective, a main object of the present invention is to provide a numerical control device including: a main controller for transmitting a plurality of first control signals, each of the first control signals including a serial data; a temporary register, The first control signal is received by the register, and the first control signal is respectively stored in the address of the temporary register; And a main control interface, which has a plurality of ports, each port has a plurality of pins, one end of each port is electrically connected to the register, and the other end of each port is electrically connected to each The connection port corresponds to one of the externally controlled components controlled interface, the connection of the main control interface respectively receives the serial data of the first control signal output by the temporary register, and the connection device respectively receives the received serial data The output is connected to the controlled interface of the controlled component, and the controlled interface can transmit a second control signal to the connection of the main control interface, and the connection of the main control terminal Passing a second portion of the control signal to the address register, the second register control signal transmitted to the main controller, the main controller by a first control signal and the second control signal is controlled by the control element.
經上述可知，由於本發明之主控制接口各個連接埠與每一個受控制元件之間的資料傳遞同樣也是獨立傳遞，可以確保各個受控制元件之間不會相互干擾。再者，藉由本發明之數值控制裝置之主控制接口可連接至各種不同種類的受控制接口，故主控制接口無需因受控制接口類型不同而需要額外增加主控制接口數量，因而降低成本。 As can be seen from the above, since the data transfer between the respective ports of the main control interface of the present invention and each of the controlled elements is also independently transmitted, it is ensured that the respective controlled elements do not interfere with each other. Furthermore, the main control interface of the numerical control device of the present invention can be connected to various types of controlled interfaces, so that the main control interface does not need to additionally increase the number of main control interfaces due to different types of controlled interfaces, thereby reducing costs.

上述本發明實施例中，數值控制裝置1傳遞串列資料至受控制元件2、3、4的方式為一非同步起停方式(asynchronous start-stop)；在本發明的較佳實施例中，是以數值控制裝置1與受控制元件2之間的資料傳遞為例：首先，主控制器11傳遞一個數位訊號為0的位元至暫存器12，此數位訊號0之位元並非包含在八個位元的串列資料中，而是一起始位元；接著，暫存器12將此起始位元0傳遞至主控制接口13之連接埠131之引腳1311、1312，使引腳1311與1312之間產生-6V~-2V的低電壓差，且引腳1311、1312輸出低電壓差至受控制元件2之受控制接口21、22；當受控制接口21、22接收到低電壓差(例如：-6V)時，則可開始接收串列資料；其中，串列資料係由一連串共八個由位元0與1所構成之位元串；之後，在串列資料傳遞結束後，主控制器11傳遞一個數位訊號為1之位元至暫存器12；其中，此數位訊號為1之位元同樣並非包含在八個位元的串列資料內，而是一結束位元；之後，暫存器12將此結束位元1傳遞至主控制接口13之連接埠131之引腳1311、1312，使引腳1311、1312之間產生+2V~+6V的高電壓差，且引腳1311、1312輸出高電壓差至受控制元件2之受控制接口21、22，當受控制接口21、22接收到高電壓差(例如：+6V)時，則可結束受控制元件2之資料傳遞。如此方式即完成一次的串列資料傳遞。同樣地，數值控制裝置1與受控制元件2之間多次串列資料的傳遞方式如同上述，且數值控制裝置1與受控制元件3、4如同上述數值控制裝置1與受控制元件2之間的串列資料傳遞方式，在此不再贅述。 In the above embodiment of the present invention, the manner in which the numerical control device 1 transmits the serial data to the controlled components 2, 3, 4 is an asynchronous start-stop mode; in a preferred embodiment of the present invention, For example, the data transfer between the numerical control device 1 and the controlled component 2 is taken as an example: first, the main controller 11 transmits a bit with a digital signal of 0 to the scratchpad 12, and the bit of the digital signal 0 is not included in the bit. In the serial data of eight bits, but a start bit; then, the scratchpad 12 transfers the start bit 0 to the pins 1311 and 1312 of the port 131 of the main control interface 13 to make the pins A low voltage difference of -6V~-2V is generated between 1311 and 1312, and pins 1311, 1312 output a low voltage difference to the controlled interface 21, 22 of the controlled component 2; when the controlled interface 21, 22 receives a low voltage When the difference is (for example, -6V), the serial data can be started to be received; wherein the serial data is a series of eight bit strings consisting of bits 0 and 1; after that, after the serial data transfer is completed The main controller 11 transmits a bit with a digital signal of 1 to the register 12; wherein the digital signal The bit numbered 1 is also not included in the serial data of eight bits, but is an end bit; after that, the register 12 transfers the end bit 1 to the port 131 of the main control interface 13. Pins 1311, 1312 cause a high voltage difference of +2V~+6V between pins 1311, 1312, and pins 1311, 1312 output a high voltage difference to the controlled interface 21, 22 of the controlled component 2, when subjected to When the control interface 21, 22 receives a high voltage difference (for example: +6V), the data transfer of the controlled element 2 can be ended. In this way, the serial data transfer is completed once. Similarly, the manner in which the serial data is transmitted between the numerical control device 1 and the controlled element 2 is as described above, and the numerical control device 1 and the controlled components 3, 4 are like the above-described numerical control device 1 and the controlled component 2 The serial data transmission method will not be described here.
上述本發明實施例中，由於主控制接口13之各個連 接埠131、132、133是分別與受控制元件2、3、4連接，故主控制接口13之各個連接埠131、132、133與受控制元件2、3、4之間的資料傳遞同樣也是獨立傳遞；換言之，主控制接口13之各個連接埠131、132、133可與各個受控制元件2、3、4互相傳遞資料，而各個受控制元件2、3、4之間不因此相互干擾。此外，本發明之數值控制裝置1亦無需傳遞資料給受控制元件2後，再依序進行將受控制元件3、4所需的資料傳遞至受控制元件3、4，因此，本發明之數值控制裝置不會降低資料傳遞效率與降低使用靈活度。 In the above embodiment of the present invention, each connection of the main control interface 13 The ports 131, 132, 133 are respectively connected to the controlled elements 2, 3, 4, so the data transfer between the respective ports 131, 132, 133 of the main control interface 13 and the controlled elements 2, 3, 4 is also Independently; in other words, the respective ports 131, 132, 133 of the main control interface 13 can communicate data with the respective controlled elements 2, 3, 4, and the respective controlled elements 2, 3, 4 do not interfere with each other. In addition, the numerical control device 1 of the present invention does not need to transmit data to the controlled component 2, and then sequentially transfers the data required by the controlled components 3, 4 to the controlled components 3, 4. Therefore, the numerical value of the present invention The control device does not reduce data transfer efficiency and reduce flexibility of use.
上述本發明實施例中，主控制接口13可同時連接不同種類的受控制元件2、3、4之受控制接口21、22、23、24、31、32、41、42，故無需因受控制元件2、3、4之受控制接口21、22、23、24、31、32、41、42類型不同而需額外新增主控制接口，因而無需額外增加成本，其中，受控制元件2、3、4之受控制接口21、22、23、24、31、32、41、42之類型例如是：RS232、RS422、RS485等類型的串列通訊匯流排，在此本發明並不設限。 In the above embodiment of the present invention, the main control interface 13 can simultaneously connect the controlled interfaces 21, 22, 23, 24, 31, 32, 41, 42 of different types of controlled components 2, 3, 4, so that it is not required to be controlled. The types of controlled interfaces 21, 22, 23, 24, 31, 32, 41, 42 of the components 2, 3, 4 are different, and an additional main control interface is required, so that no additional cost is required, wherein the controlled components 2, 3 The type of the controlled interface 21, 22, 23, 24, 31, 32, 41, 42 of 4 is, for example, a serial communication bus of the type of RS232, RS422, RS485, etc., and the invention is not limited thereto.
