Description of the Invention: [Technical Field] The present invention relates to a monitoring circuit design of a power supply circuit, and more particularly to a monitoring circuit for saving an electrical outlet group. [Prior Art] A conventional computer outlet set is a socket group having a power plug and a plurality of sockets, and the sockets are connected to each other in parallel. Plug the power plug ® into a socket or an extension cord when in use, but only control the power supply by the power switch set on the outlet group. When the user turns off the personal computer, in addition to shutting down the host computer of the personal computer, other computer peripheral devices connected to the host computer of the personal computer need to be turned off one by one to save the power of the peripheral device, thereby causing Inconvenience in use. Different prior art techniques have been developed for control circuits for computer outlets. In the patented art, for example, Patent Publication No. 582588, in which a power supply state control stomach circuit for a socket set for a computer is disclosed. A load detecting component having a predetermined resistance value is connected to one of the power sources of the AC power source, and the other end of the load detecting component is connected to the first end of the first socket of the socket group. The input end of the amplifying circuit is also connected to the first end of the first socket, and the voltage difference generated when the current is passed through the load detecting element is amplified. Comparing whether the voltage outputted by the amplifying circuit input at the input terminal thereof is higher than a predetermined voltage by a comparison circuit, and outputting the voltage generated after the comparison is outputted from the output terminal thereof, and generating the output voltage through the receivable comparator circuit The electronically controlled switch of the action of the switch controls the second socket and the sockets connected in parallel thereafter. 201009563 When the electrical device inserted in the first socket is not energized, the electrical control relationship is in an open state, so that the second end of the socket and the second socket connected in parallel with the second socket is disconnected from the second end of the first socket Unable to supply power. When the electric appliance inserted in the first socket is energized, the electric control switch is made to be a passage, so that the second socket and the socket connected to the rear thereof are connected to the AC power source and the second end passage of the first socket is further provided. power supply. SUMMARY OF THE INVENTION The technical problem to be solved by the present invention is that a master-slave architecture is commonly used in today's electrical load connection types, such as a host computer, a list machine, a display, and a scanner, which are composed of a master and slave load architecture. The host computer acts as the master device, while the list machine, display, and scanner act as slaves. As long as the computer host is turned off, the lister, display, and scanner do not need to continue to supply power. Otherwise, even if each device is in standby state, it actually continues to consume power. For example, in the main control and subordinate load architectures, the TV, the VCR, and the external sigma are used as the main control devices, while the VCR and external speakers play the slave load. As long as the TV is turned off, the recorder and the external camera will not need to continue to supply power. Otherwise, even if each device is in the standby state, it will continue to consume power. Traditional power supply types are not suitable for applications with master and slave load architectures. The control circuit of the computer socket group in the previous case uses a load detecting component connected in series with the first socket to have a predetermined resistance value to sense the current value flowing through the main current of the socket of 201009563, and then through the amplifying circuit. The difference between the main current that is amplified by the input terminal and the voltage generated by the load detecting component. ❹ Finally, by comparing the circuit, the voltage of the amplified electrical input input to the input terminal is higher than the predetermined voltage, and the voltage generated by the money is outputted from the output terminal thereof and generated through the output voltage of the receivable comparator circuit. The electronic control of the action of the switch _ to control the second socket and the sockets connected in parallel. Since the computer has a desktop type and a notebook type, since the current signal of the notebook computer is weak, the previous case cannot be used to properly control the slave circuit opening and closing when the notebook computer is turned off and in standby mode to save power. . However, although the first socket and the socket connected to the rear thereof can be controlled by the load detecting element connected in series with the first socket, the computer main_standby current on the __ socket changes with the voltage of the alternating current power source, that is, When the power supply voltage = high, the standby current will decrease. When the power supply voltage drops, the current will rise and the same standby power will be presented. However, the standby voltage = and: change, so the preset current value is used to control the second socket and the live state. The parent-supplied power supply voltage of the company's mains is not fixed in the socket group—the socket failure caused by the problem of the line overloading. The control circuit of the computer socket group in the previous case only = whether the test socket has normal functions for judgment. It is not possible to know the condition of the socket and the socket to which it is connected. The purpose of the circuit is to provide an outlet group with a monitoring function that saves power. Integrating the control circuit into a section 201009563 Another object of the present invention is to provide an energy-saving outlet group that can synchronously control the slave loop power supply by turning on and off the computer. Technical Solution for Solving the Problems The present invention is directed to solving the problems of the prior art by providing a total loop current detecting circuit on a main circuit and a slave loop current detecting circuit in the slave circuit. The micro-controller is used to monitor the outlet group by accurately calculating the current value of the incoming main loop and the slave loop current. β When the load connected to the main circuit is off or standby, the power measured by the monitoring circuit will be lower than the set power value, so the power supply of the slave circuit will be turned off, so that the load of the slave circuit is turned off, and the power saving effect can be achieved. . According to the technical means adopted by the present invention, the present invention can save the micro-controller of the monitoring circuit of the power socket group through the invention when the host of the personal computer inserted in the socket of the main circuit is turned off. The generated slave loop control signal is used to control the slave circuit switch unit to synchronously close the computer peripheral devices such as the display, the speaker, the printer, etc., which are inserted into the socket of the slave circuit, thereby saving the standby power of the computer peripheral devices on the slave circuit. It can solve the inconvenience of needing to switch the power of each computer peripheral device on the slave circuit one by one. The monitoring circuit of the present invention can be used as a monitoring of the power supply conditions of the entire circuit. The specific embodiments of the present invention will be further described by the following examples and the accompanying drawings. 201009563 [Embodiment j 1 is shown in the figure, which shows that the power saving broadcast group of the present invention is two:::::Road::圏' map shows the first compact T1, and the day 'touch iZ is formed between The main circuit includes a -first socket 2 in the main circuit L1, and a total loop current detecting circuit 3 〇 φ, the first socket 21 13 2 is connected to the main circuit L1.
