Intelligent switching-on and switching-off device for office power supply

Technical Field

The utility model relates to a power technical field, concretely relates to office power intelligence is thrown and is stopped device.

Background

Along with office building consumer progressively increases, lacks corresponding administrative measure simultaneously, and the power consumption is used up at will, and extravagant power consumption phenomenon is comparatively general, leads to the power consumption to be high. Especially, the power consumption in the non-working time period is very high, and the power consumption cost of the office building is greatly improved. The reason why the power consumption is so high in the non-working time period is that people forget to turn off the electric equipment after leaving the office, or only turn off part of the electric equipment, and equipment such as an air conditioner, a computer screen, a printer, an electric kettle and the like is turned on all night. These waste power and also create a safety hazard.

The utility model provides a device is put into operation to office power intelligence, includes direct current battery, microwave sensor, STM32F42 singlechip treater and ac contactor, the direct current battery links to each other with STM32F42 singlechip treater and ac contactor, the output of microwave sensor link to each other with the input of STM32F42 singlechip treater, the output of STM32F42 singlechip treater passes through triode T and links to each other with ac contactor's signal trigger end, ac contactor's normally closed contact links to each other with the office power cord.

Preferably, the output end of the STM32F42 singlechip processor is connected with the base of a triode T, and the collector of the triode T is connected with the signal triggering end of the ac contactor.

Preferably, the input end of the office power supply is also connected with a main air switch.

Preferably, a delay program is arranged in the STM32F42 single chip microcomputer processor, and the delay time is set to be 30 min.

The utility model has the advantages that: simple structure uses in a flexible way, comes the testing personnel whether at the office through setting up microwave sensor, then controls the break-make of whole office power through STM32F42 singlechip treater and ac contactor, reduces the power consumption of non-operating time period consumer, reduces office power consumption potential safety hazard simultaneously.

the system comprises an air switch 01, an electric device 02, a direct current battery 1, a microwave sensor 2, an STM32F42 single chip processor 3 and an alternating current contactor 4.

Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the functions of the invention easy to understand, the invention is further explained by combining the specific embodiments.

As shown in fig. 1-2, a device is put in to office's power intelligence, including direct current battery 1, microwave sensor 2, STM32F42 singlechip processor 3 and ac contactor 4, direct current battery 1 links to each other with STM32F42 singlechip processor 3 and ac contactor 4, microwave sensor 2's output link to each other with STM32F42 singlechip processor 3's input, STM32F42 singlechip processor 3's output passes through triode T and links to each other with ac contactor 4's signal trigger end, ac contactor 4's normally closed contact links to each other with the office power cord. Whether come the testing personnel at the office through setting up microwave sensor 2, then come the break-make of controlling whole office power through STM32F42 singlechip treater 3 and ac contactor 4, reduce the power consumption of non-operating time period consumer, reduce office power consumption potential safety hazard simultaneously. The microwave sensor 2 adopts a microwave human body radar sensor, and can accurately detect a human body.

The output end of the STM32F42 single chip microcomputer processor 3 is connected with the base electrode of the triode T, and the collector electrode of the triode T is connected with the signal trigger end of the alternating current contactor 4.

The input end of the office power supply is also connected with a main air switch. The intelligent switching device for the office power supply is connected between the main air switch and the electric equipment, belongs to additional equipment and cannot change the function of the main air switch.

A delay program is arranged in the STM32F42 single chip microcomputer processor 3, and the delay time is set to be 30 min. If the person is re-detected within 30min, the timing is restarted.

The specific implementation mode and principle are as follows:

at least 3 pairs of 6 terminals (the number of pairs is selected according to needs) can be arranged at two ends of the intelligent switching device for the office power supply for connecting power lines, when the intelligent switching device for the office power supply is installed, the power line coming from the air switch can be connected to one terminal, then the other terminal is connected to the power line for the office, namely, the intelligent switching device for the office power supply is connected to the rear side of the air switch of a room in series, as shown in fig. 2. Microwave sensor 2 monitors whether someone is in the office at any time, if nobody in the office, then microwave sensor 2 output an effectual low level signal, the time delay procedure in STM32F42 singlechip treater 3 begins work simultaneously, delay 30 minutes after, if the office still is nobody, output a control signal, add the base to the triode, make the triode switch on, the coil that connects ac contactor 4 on the projecting pole gets electric, electromagnetic attraction disappears, make normally open contact reset, the disconnection after the normally closed contact action of ac contactor 4 of connecting power cord, thereby cut off the office power. Between this, if someone gets into the office, then microwave sensor 2 senses someone and gets into, and output a high level and give STM32F42 singlechip treater 3, makes the timing program in STM32F42 singlechip treater 3 reset again simultaneously, makes the ac contactor coil electrified, produces electromagnetic suction, makes normally open contact closed, and the office power closes, resumes the power supply. The DC power supply required by the work of each element in the office power supply intelligent switching device is taken from the DC battery 1.

Based on the above, the utility model discloses simple structure uses in a flexible way, whether comes the measurement personnel at the office through setting up microwave sensor, then controls the break-make of whole office power through STM32F42 singlechip treater and ac contactor, reduces the power consumption of non-operating time period consumer, reduces office power consumption potential safety hazard simultaneously.

It will be appreciated by those skilled in the art that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The embodiments disclosed above are therefore to be considered in all respects as illustrative and not restrictive. All changes which come within the scope of the invention or which are equivalent to the scope of the invention are embraced by the invention.
