DESCRIPTION OF THE INVENTION: TECHNICAL FIELD The present invention relates to a control system, and more particularly to a tandem control system in which a single core is connected in series and has a feedback mechanism. " [Prior Art] Please refer to Figure i, a known host! Controlling the control systems of most sub-machines 〇, Η, 14, and 16 'is mainly connected in a dendritic distribution in parallel. When the host i wants to control a certain sub-machine, such as sub-machine 1 (), as long as Emission - the slave 1G can correspond to the received control signal, and the corresponding slave 10 will act 'and simultaneously feedback a signal to inform the host! Has been activated, but most of them are only one of the CPU and the sub-machine - the CPU's mutual transmission 2 is correct, and the controlled object is often ignored. The currently known conventional control methods are mostly RS_232. & Rs_485 and other transport connections. However, as shown in FIG. 1, the state of the dendritic distribution connection is required to be individually wired for each of the T machines 10, 12, 14, and 16. When there are a large number of sub-machines in the system, the wiring of the control lines becomes very large. Complex, so the wiring cost is quite high, and its so-called feedback mechanism is actually a dummy as described above, because it is reasonable to say that the corresponding controlled production of the slave 10 must be activated after the completion of the operation, the feedback signal tells the host i to act. It has been completed, but in the conventional dendritic distribution state shown in Figure 1, it is usually at the receiving end of the internal CPU of the slave 10 - receiving the host! After the control signal, the transmitting end of the internal CPU of the slave 10 immediately feeds back a signal to notify the host i that the data has been received, so whether the object driven by the corresponding slave 10 is actually activated in 200841188 is not known. Therefore, the feedback mechanism of the conventional knowledge is only at the beginning of the signal transmission, so how to improve the authenticity of the control system has become an active research and development topic in the industry. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a tandem control system that is extremely simple in wiring and that can effectively implement a feedback mechanism. Thus, the serial connection control system of the present invention comprises: at least one host, and a plurality of slaves. The host has a first central processing unit that can output an address encoding and control signal, a first signal processing electrically connected to the first central processing unit, and an electrical connection with the first signal processing unit. The address encoding and control signal is sent out by the first transmitting unit, and an operation panel electrically connected to the first central processing unit. Each of the slaves is electrically connected to the host in series and has a second transmitting unit that can switch the signal direction in time and is connected in series with the host, and a second signal processing unit electrically connected to the second transfer sheet 70, a first central processing unit privately connected to the second signal processing unit and capable of unpacking the address encoding and control signals sent by the host, and a control signal capable of receiving the decoding output of the second central processing unit and driving the slave The actuating driving unit is electrically connected to the second central processing unit and can detect and transmit the feedback signal of the slave operating device to the detecting unit of the second central processing unit. The effect of the present invention is that after the controlled slave receives the address code and control signal output by the host through the second transmission unit, the output control signal is decoded to the driving unit via the first central processing unit to drive the driver. When the machine detects that the slave unit is activated, it feeds back a signal to 200841188. • The second central processing unit is located early, and the second central processing unit switches the direction of the transmission in time. The second signal processing unit and the feedback signal are fed back to the host, so that the controlled machine transmits the feedback data to the host via the original path after the operation.

Each of the slaves 3 and the host 2 are electrically connected in series with the single-core wires 4 to form a closed loop. Each slave 3 has a second transmitting unit that can switch the signal transmission direction in time and is connected in series with the host 2, such as a second signal processing unit 31 electrically connected to the second transmitting unit 30, and the second signal processing The unit 31 is electrically connected to the second central processing unit 32 that can decode the address code and control signal sent by the _ 2, and can receive the control signal decoded by the second central processing unit 32 and drive the sub-machine 3 The driving unit and the second central processing unit f are connected to the rain and the soil t 32, and can detect and transmit the feedback signal of the slave unit 3 after the actuation of the slave unit 3 to the first central processing. Know unit 34. The first direction switch 301 and the first direction switch 301 have a first direction switch 301 and a first direction switch 301. The first direction transmitting end 3011 and the outer a/ and the first one direction receiving end 3012 of the switch direction can be controlled by the central processing unit 32, and the second direction switch 302 is also right. The first signal processing unit 31 further includes a first signal processing component 3 and a second signal. The first signal processing unit 31 further includes a first signal processing unit 3 and a second signal. The first signal processing component 311 is electrically connected to the first direction switching switch 301 and the second central processing unit 32, and the second signal processing component 312 and the second direction switching switch 302 and the first The two central processing units 32 are electrically connected. When the user intends to make the specific sub-machine 3 of the host 2 control system actuate, the operation panel 26 can be used to directly command the host 2, and the host 2 is first generated by the first central processing unit 2 The address encoding and control signals corresponding to the slave 3 can be encoded. In the first preferred embodiment, the address encoding and control signal is a long string of digital signals, and includes a start bit and an end bit, and then the first center The address encoding and control signals output by the processing unit 20 are processed by the first processing element 221 and the second processing element 222 of the first signal processing unit 22, and then passed through the first switching switch of the first transmitting unit 24. The first transmitting end 2411 and the second transmitting end 2421 of the second switching switch 242 are emitted along the single-core wire 4, and when the ending bit is sent from the first transmitting end 241 and the single-core wire 4 After exiting, the first central processing unit 2 controls the signal transmission direction of the first switching switch 241 and the second switching switch 242 of the first transmitting unit 24 from the first transmitting end 2411 and the second transmitting to 2421 Switching to the positions of the first receiving end 2412 and the second receiving end 2422 and preparing to receive the reply of the sub-machines 3. Referring to Figures 5 and 6, the line relationship when the feedback signals are transmitted by the respective sub-machines 3 in the figure, since the entire control system is connected in series, and the first direction in the second transmission unit 3G of each sub-machine 3 9 200841188 The switch switch is preset to be in the position of the first direction receiving end 3〇12, so the signal output by the host 2 will flow through the first direction receiving end 3G12, and via the second signal processing unit 3! The first signal processing component 311 processes the second central processing unit 32 for its back end for decoding. The slave 3 corresponding to the decoded address will continue to operate after decoding, and the slave 3 that is not corresponding to the decoded address will not operate. At this time, the second central processing unit 32 outputs a control signal to the driving unit to drive the driver: function actuation (for example, lighting the light or starting the motor operation), and the detecting unit % detects the child. After the actuation, the feedback signal is sent to the second central processing unit 32. The second central processing unit 32 processes the feedback signal via the second signal processing component 312 and switches the second transmission unit 30 in time. The one direction switch 3〇1 and the second direction switch switch gather, so that the signal transmission direction is switched from the first direction receiving end 3〇12 and the second direction receiving end 3· to the second direction transmitting end bribe and the second party (4) the end 3021, and the feedback signal is transmitted to the host 2 via the single feed line 4. At this time, the first switch 241 and the second change switch 242 of the first transfer unit 24 of the host 2 have been switched to the The first receiving end 2412 and the receiving end 2422 are located at the position 'the feedback signal is transmitted to the first signal processing unit 22, and then output to the _20' of the host to complete the entire control and the sub-machine 3 Signal after actuation Feedback action. The user can surely know that the child machine 3 is actually actuated, so that the bite can be implemented to perform the feedback mechanism. It is worth mentioning that after the slave 3^ returns the feedback signal, the second transmitting unit 3G switches to the preset 10 200841188 receiving position, waiting to receive the address of the host 2 next round. Ma and control signals. Referring to FIG. 7, a second preferred embodiment of the serial connection control line of the present invention is substantially the same as the first embodiment, except that the system includes two hosts 2 And a single core wire 7 is connected in series to form an annular closed back 4 . The serial connection control system of the invention can be widely used for the wiring control of the multi-master 2, in the same closed series circuit, since the control signal and the feedback signal can be transmitted to each of the sub-machines 3 and the mother-host separately. 2' Therefore, different control objects can be individually controlled by a plurality of hosts 2, and the manner of operation thereof is the same as that of the previous embodiment, and will not be described herein. ' / It can be seen from the above description that the serial connection control system of the present invention is designed, the whole system uses single-core wires 4, 7 in series with the host 2 and the slave 3, and the first and second corresponding to the controlled slave 3 The direction switching switch can control the switching signal transmission direction in a timely manner, so that the controlled slave unit 3 can surely transmit the feedback signal to the host 2 via the path of the single-core wires 4 and 7 after being actuated, so the money is sent to the slave unit. 3 After the operation, the data is actually fed back to the host 2, and the transmission method is different from that of the conventional #玥Μ 肖 RS-232 or RS_485. It is more suitable for the multi-host and multi-sub-machine sharing the single single-feed line 4 string. It is true that the present invention can achieve the object of the present invention. Therefore, the present invention is not only unprecedented, but also available for industrial use. The above is only the two preferred embodiments of the present invention, and the scope of the present invention is not limited thereto, that is, the simple equivalent change according to the scope of the present invention and the description of the invention.
