Embodiment Construction

[0019] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples, and detailed descriptions are as follows with accompanying drawings:

[0020] As shown in Figure 1, pin 1 of the human body infrared sensor chip RE200 is connected to the positive terminal of the power supply, and pin 2 is connected to the positive terminal of the amplifier UB. When there is human intervention, its pins 1 and 2 are connected to the positive terminal of the integrated operational amplifier UB. At high level, one end of the shunt resistor R5 is connected to the positive end of the integrated operational amplifier UB, and the other end is grounded; the integrated operational amplifier UB, the resistors R1, R2 and the capacitor C form a voltage follower with delay. The output terminal of the integrated operational amplifier UB is connected to the inverting input terminal of the integrated operational amplifier UA. The non-i...

Abstract

The invention relates to an energy-saving type intelligent controller and the control method thereof, which comprises a display module, a monolithic processor, a human body infrared sensor, an integrated operational amplifier, a comparator and an optical coupler. The output terminal of the sensor is respectively connected with the two input terminals of the comparator through a voltage follower with time delay function and a reference voltage obtained by dividing the voltage through two resistors, after being compared, two signals are input into the input terminal of the optical coupler by the output terminal of the optical coupler, the output terminal of the optical coupler outputs the signals to the input terminal of the monolithic processor, and after being judged, the signals whether or not are displayed are input into the display module. Because the invention leads a light activated element to be arranged in the controller and to be processed by a circuit, when people stand in front of the controller, a liquid crystal display screen enters a display state, when no person stands, the controller does not enter into the display module, the signal processing chip of the controller keeps in the dormant state, and the controller only protect and detect a power distributing network. In the way, the power consumption of the controller is greatly decreased, the operating time is shortened, and the protection precision of the controller is improved.

Description

Technical field [0001] The invention belongs to a low-voltage switch controller, and particularly relates to an energy-saving intelligent controller and a control method thereof. Background technique [0002] With the rapid development of science and technology today, energy saving and consumption reduction have become the prerequisite and goal of the development of various industrial enterprises, and it is also a new indicator to measure the technological level of an enterprise. The display elements of advanced low-voltage switch controllers mostly use LCD screens. However, the liquid crystal display takes up a lot of program space and has a large power. Summary of the invention [0003] The present invention provides an energy-saving intelligent controller that reduces the power consumption of the controller and a control method thereof in order to solve the technical problems existing in the known technology. [0004] The technical scheme of the energy-saving intelligent cont...
