Problems solved by technology

[0003] In order to solve the problem of a single working state of household electrical appliances under different conditions in the prior art, the present invention provides an electrical equipment with state detection and memory functions, and uses the controller of the electrical equipment to detect the level duration of a specific pin, In this way, the control system operates in different states, and this state is memorized. When the electrical equipment is powered on again, the control system automatically operates in this state, which meets the multi-state requirements for the operation of home appliances.

Embodiment Construction

[0013] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0014] The hardware circuit of the present invention is as shown in Figure 1, and processor UM1 adopts a model to be the MCU chip of PIC16F676 to realize, and its 7 pins are connected to specific key detection circuit, specific key and standby key are shared among the present invention, promptly select the standby key of electrical equipment As the specific key, by detecting the continuous pressing time of the standby key, the effective switching of the system working mode when the electrical equipment is powered on by AC is realized. Pin 2 of the processor UM1 receives the remote start command output by the remote control receiving circuit, and pin 6 outputs a high-level or low-level control signal to the main power relay to control whether the main power circuit starts to work. Pin 8 receives the standby status signal sent by the ma...

Abstract

The invention relates to an electric appliance with state detecting and memory functions, wherein it comprises: button state detector for real time detecting the pressed time of special button; judger for comparing the pressed time with preset time, to set the working mode of system when it is powered again; a close command receiver for setting the electric appliance to automatically enter into waiting mode when receives close command and being powered again. The invention detects the pressed time of special button to switch the system working modes accurately, while it uses automatic start mode in workshop, and uses low-power waiting mode in family. The invention has simple circuit and software, to be used in video media device.

Description

technical field [0001] The invention belongs to the technical field of home appliances, and in particular relates to a detection and memory technology that uses a controller of an electrical appliance to detect the level duration of a specific pin, thereby controlling the system to run in different states. Background technique [0002] In the circuit design of home appliances, the system is often required to be in different states under different conditions. For example, in the workshop production line, in order to improve production efficiency, electrical equipment is required to be able to start automatically after AC power is turned on to save remote start-up In the process of using the user, in order to prevent the electrical equipment from starting abnormally due to the fluctuation of the grid voltage when the user is not at home, the system is required to be in a low-power standby state after the AC power is turned on. After the remote start signal, enter the system ru...
