Description

An IP core with memory function to detect whether the electrical appliance is in standby

technical field

The utility model relates to the field of electric appliance detection, in particular to an IP core with a memory function for detecting whether the electric appliance is in standby.

Background technique

Energy saving and emission reduction is a systematic project, which not only depends on the transformation of production methods and the development of new energy-saving products, but also depends on the intelligent management of equipment. Due to the electrical characteristics of circuit design and physical components, power-consuming products still consume a certain amount of power when they are turned off or in standby. Aiming at the current electricity consumption habits that people usually do not cut off the power supply of electrical equipment after using them up, causing them to consume a large amount of energy in standby, a device that can automatically detect whether the electrical equipment is in standby and intelligently cut off the electrical energy has become very important.

At present, the devices that cut off the power according to the standby state of the electrical appliances mainly include multi-functional smart sockets and adapters, etc. These devices have the following problems: the lower limit value of the electrical current or voltage is directly set, the flexibility is poor, and misjudgment often occurs; only The detection function has no way to judge by itself, and the user needs to judge whether the power is off, and the intelligence is low; it is made into a practical product, but it is not made into a module, and the promotion type is poor.

Utility model content

The technical problem to be solved by the utility model is to overcome the deficiencies in the prior art and provide an IP core with a memory function that can be placed on electrical appliances such as electrical appliances, power strips and sockets to detect whether the electrical appliances are in standby.

In order to solve the problems of the prior art, the technical solution adopted in the utility model is:

An IP core with a memory function for detecting whether an electrical appliance is in standby, including a control module, a current detection module, a storage module, a power on-off module and a human-computer interaction module; the control module is connected to the current detection module, the storage module, and the power supply respectively. The disconnection module is connected with the human-computer interaction module, and the current detection module is connected with an external power supply. The control module is used to realize the overall detection, comparison, storage and shutdown control; the current detection module is used to detect the current value; the storage module is used to store the current value and its corresponding state; the power supply The power-off module is used for switching on and off the power supply; the human-computer interaction module is used for human-electrical interaction. The utility model is provided with a control module, a current detection module, a storage module, a power on-off module and a human-computer interaction module, so as to intelligently cut off the power supply of standby electrical appliances to realize energy saving.

The IP core is also provided with load plug jacks for connecting loads, and the load plug jacks are respectively connected with the power on-off module and the storage module. In this way, the IP core is placed on electrical appliances such as electrical appliances, power strips, sockets, etc. through the load plug jack, so as to realize intelligent power cut off of standby electrical appliances.

The control module can be realized with some specific single-chip microcomputers, including 8-bit 51-core single-chip microcomputers such as 89C51/89C52/89C53/89C54/89C58, new suffix 89C51RD and RC series with ISP; also including 16-bit single-chip microcomputers such as ATMEL AVR MCU, TI MSP430 series, ST STM32 series; 32-bit MCU such as ARM7, ARM9 series, ST STM32W103/107 series, etc.

The current detection module includes an analog-to-digital converter, and the analog-to-digital converter converts the analog current signal into a digital current signal and sends it to the control module. Because most of the chips of the control module are digital signals, they can only receive digital signal values, while the current value of the load is an analog signal, which requires an analog signal to digital signal conversion, which is usually realized by some analog-to-digital converters, and the current detection The module's analog-to-digital converter meets this requirement.

The storage module is an EEPROM memory. The storage module is the main module to realize the memory function. It stores different working status data, including the current value and its corresponding on-off status. At the same time, the storage module also needs to delete unnecessary stored data, so it is very suitable to use EEPROM memory.

The human-computer interaction module is a button for manually operating the load power on and off. For example, when the control module notifies the power supply on-off module to cut off the circuit according to the current stored value of "off", if a person manually presses this button to switch on the circuit, the control module will modify the value in the memory after detecting this state. The state of the corresponding current value is "on" and stored, then the next time this value is detected, the circuit will not be cut off, so that the interactive information obtained through the human-computer interaction module will be remembered, realizing intelligence.

Compared with the prior art, the utility model sets the control module, the current detection module, the storage module, the power on-off module and the human-computer interaction module, so as to intelligently cut off the power supply of the standby electrical appliances to realize energy saving, which solves the problems of the prior art. And the problems of poor flexibility, low intelligence, and no modularization in the product; at the same time, let users develop a good habit of turning off electrical appliances, and the electrical appliances will remember the user's electricity consumption habits, and realize the intelligence of electrical appliances according to this habit It realizes energy saving and emission reduction, which is of positive significance to building a conservation-oriented society.

When the current value is less than the threshold value, it will Automatically power off and not save; when it is greater than the threshold, a new working state will be generated: the current value is this current value, and the state is "on", that is, the circuit will remain on when the stored value is not found, and then connect Come down and wait for the human-computer interaction.
