     DESCRIPTION OF THE PREFERRED EMBODIMENT 
       [0012]    The following description of the preferred embodiment is provided to understand the features and the structures of the present invention. 
         [0013]    Please refer to  FIG. 1  and  FIG. 2 , which are a framework view and a block view showing a preferred embodiment according to the present invention. As shown in the figures, the present invention is a breaker control system using power frequency carrier, comprising at lease one high-pressure facility  1  and a monitoring device  2 . 
         [0014]    The at least one high-pressure facility  1  is an oil breaker  11  connected with an engine  111 ; a vacuum breaker  11   a  connected with a chamber  111   a;  an air breaker  11   b  connected with a chamber  111   b;  an air breaker  11   b  connected with a chamber  111   b;  a gas breaker  11   c  connected with a burner  111   c;  or a combination of the above components coordinated simultaneously or separately according to a requirement. And the oil breaker  11 , the vacuum breaker  11   a,  the air breaker  11   b  and the gas breaker  11   c  each is connected with a first power frequency carrier unit  12 . 
         [0015]    The monitoring device  2  comprises a control member  21  and a display unit  22 , where the monitoring device  2  is connected with a second power frequency carrier unit  23 ; and the second power frequency carrier unit  23  is connected with the first power frequency carrier unit  12  through an indoor power unit  3 . Thus a novel breaker control system using power frequency carrier is obtained. 
         [0016]    Please refer to  FIG. 3 , which is a block view showing a first power frequency carrier unit and a second power frequency carrier unit. As shown in the figure, a first power frequency carrier unit  12  comprises a single-chip control module  121 ; a power carrier module  122  having a transmission rate of 1200 BPS (bit per second); a power module  123  supplying power for the single-chip control module  121  and the power carrier module  122 ; an input unit  124 ; and an output unit  125 , where the single-chip control module  121  comprises an output controller  1211 , a relay  1212 , a control unit  1213  a communication interface  1214  and an input receiver  1215 . 
         [0017]    A second power frequency carrier unit  23  comprises a single-chip control module  231 ; a power carrier module  232  having a transmission rate of 1200 BPS; a power module  233  supplying power for the single-chip control module  231  and the power carrier module  232 ; an input unit  234 ; and an output unit  235 , where the single-chip control module  231  comprises an output controller  2311 , a relay  2312 , a control unit  2313 , a communication interface  2314  and an input receiver  2315 . 
         [0018]    The control unit  1213 , 2313  either in the first power frequency carrier unit  12  or the second power frequency carrier unit  23  is a 8051 single-chip as a processing unit with a good inner structure, whose working frequency is up to 16 MHz together with a 4k size of electrically programmable and erasable ROM (Read Only Memory) together with eight input pins and eight output pins Each of the first and the second relay  1212 , 2312  is located at the output pins of the 8051 single-chip to quarantine the circuit for securing and ensuring the operation of the 8051 single-chip. Each 8051 single-chip contains a full-duplex communication interface inside, which are the first and the second communication interfaces  1214 , 2314 . Each communication interface  1214 , 2314  is an RS232 interface to simultaneously transfer and receive data from outside. The operational signals in the 8051 single-chip are on a TTL (transistor-transistor-logic) level (0 voltage set as logic 0; +5 voltage set as logic 1) and each communication interface  1214 , 2314  is a serial communication interface to transfer or receive data in a form of bit series. 
         [0019]    Please refer to  FIG. 4  and  FIG. 5 , which are a view showing a state of use and a block view showing the state of use of the preferred embodiment. As shown in the figures, the present invention is applied in a factory  4  having high-pressure facilities  1 , such as an oil breaker  11   a  vacuum breaker  11   a,  an air breaker  11   b  and a gas breaker  11   c.  A monitoring device  2  is equipped in a remote control room  5  for the factory  4 . A first power frequency carrier unit  12  of the high-pressure facility  1  and a second power frequency carrier unit  23  of the monitoring device  2  are plugged in sockets of an indoor power unit  3  to connect the first power frequency carrier unit  12  and the second power frequency carrier unit  23 . 
         [0020]    When using the high-pressure facility  1 , the oil breaker  11 , the vacuum breaker  11   a,  the air breaker  11   b  or the gas breaker sends a state-of-use signal to the second power frequency carrier unit  23  by the first power frequency carrier unit  12  through the indoor power unit  3  to be displayed on a display unit  22 . When the high-pressure facility  1  transfers the signal, the first frequency carrier unit  12  integrates and encodes the signal through a single-chip control module  121 , a power carrier module  122  and a power module  123 ; a transmission mode and speed are detected and set by the single-chip control module  121 ; and the signal is transferred by an output unit  125  of the first power frequency carrier unit  12  through the indoor power unit  3 . Thus the sate-of-use signal of the high-pressure facility  1  is transferred to the second power frequency carrier unit  23  of the monitoring device  2 . An input unit  234  of the second power frequency carrier unit  23  receives the signal and the signal are decoded through a single-chip control module  231 , a power carrier module  232  and a power module  233 . Then the status of the high-pressure facility  1  is determined and is outputted from an output unit  235  to be shown on the display unit  22 . 
         [0021]    When the high-pressure facility  1  operates well, no abnormal signal is outputted; and a normal signal is sent from the first power frequency carrier unit to the second power frequency carrier unit to display ‘normal’ on the display unit  22 . An engineer monitoring or maintaining the facilities in the control room  5  is thus informed of the wellness of the high-pressure facility  1 . 
         [0022]    When an abnormal situation happens to the high-pressure facility  1 , the high-pressure facility  1  receives an abnormal signal for the oil breaker  11 , the vacuum breaker  11   a,  the air breaker  11   b  or the gas breaker  11   c.  The abnormal signal is then sent from the first power frequency carrier unit  12  to the second power frequency carrier unit  23  to be displayed on the display unit  22 . An engineer monitoring or maintaining the facilities in the control room  5  is thus in formed of the abnormal situation of the oil breaker  11 , the vacuum breaker  11   a,  the air breaker  11   b  or the gas breaker  11   c;  and the engineer responds to the abnormal situation of the high-pressure facility in the mean time by shutting some breaks or all breaks through the control member  21 . By doing so, a remote control is obtained to shut the oil breaker  11 , the vacuum breaker  11   a,  the air breaker  11   b  or the gas breaker  11   c  in advance so that the engineer maintains the high-pressure facility safely. 
         [0023]    To sum up, the present invention is a breaker control system using power frequency carrier, where, by connecting a first power frequency carrier unit and a second power frequency carrier unit through an indoor power unit, at least one high-pressure facility is control led remotely.

Therefore, simple modifications or variations belonging to the equivalent of the scope of the claims and the instructions disclosed herein for a patent are all within the scope of the present invention.
