Description

A kind of dormitory bedside socket safety device

technical field

The utility model relates to a bedside socket in a dormitory, which is a device capable of preventing students from being in an unattended state or plugging a plug into the socket to cause danger.

Background technique

At present, modern dormitories in universities are constantly replacing old dormitories. In some dormitories, sockets are installed on the wall at the head of the bed for the convenience of students' electricity use or study at night. While these sockets are convenient for students to use electricity, they also bring potential safety hazards. For example, some students directly unplug the mobile phone after charging the mobile phone and forget to unplug the charger from the socket. This not only wastes electric energy, but more importantly The most important thing is that there are high potential safety hazards, and fires caused by not unplugging the charger happen from time to time in university dormitories. Therefore, a new type of socket is needed to avoid the above-mentioned risks.

Utility model content

The purpose of the utility model is to overcome the deficiencies in the above-mentioned prior art and provide a safety device for bedside sockets in dormitories. The dormitory bedside socket has a relatively simple structure and is easy to install. The single-chip microcomputer is used as the main control unit of the whole system, and the infrared sensor is used to monitor whether there is anyone on the bed. This utility applies the patch switch to the safety device of the socket, transmits the signal of the plug inserted into the socket to the single chip microcomputer for analysis and processing, and uses the voice signal to prompt the signal input by the user, and automatically cuts off the power supply in the state of no response , to avoid the occurrence of danger.

In order to achieve the above purpose, the technical solution adopted by the utility model is: a dormitory bedside socket safety device, which is characterized in that it includes a single-chip microcomputer, an infrared sensor for monitoring whether there is a person on the bed, and an infrared sensor for monitoring whether the socket is inserted. SMD switch, a voice prompt unit for sending voice signals, a relay for cutting off the power supply of the socket, and a circuit unit for supplying power to the single-chip microcomputer; the input end of the single-chip microcomputer is connected with the infrared sensor, and the single-chip microcomputer The output end of the chip is connected to the voice signal prompt unit, the power supply circuit unit is connected to one end of the patch switch, the other end of the patch switch is connected to the power supply end of the single-chip microcomputer, and the output terminal of the single-chip microcomputer is connected to the relay connected.

The above-mentioned bedside socket safety device in a dormitory is characterized in that the associated single-chip microcomputer is an 89C52 single-chip microcomputer.

The above-mentioned bedside socket safety device in a dormitory is characterized in that the user must be present to complete operations such as power consumption and charging, which reduces the risk of fire in the dormitory.

The utility model has the following advantages:

(1) The utility model monitors whether the socket is inserted by a plug through a patch switch, and transmits the information number to the single-chip microcomputer, and the price is cheap.

(2) The utility model can ensure that the electricity operation can only be completed when people are present, which not only reduces risks, but also saves energy.

The technical solutions of the present utility model will be further described in detail through the drawings and embodiments below.

detailed description

As shown in Figure 1, a dormitory bedside socket safety device includes a single-chip microcomputer, an infrared sensor for monitoring whether there is someone on the bed, a patch switch for monitoring whether the socket is inserted, and a voice signal for sending out voice signals. A prompting unit, a relay for cutting off the power supply of the socket, and a circuit unit for supplying power to the single-chip microcomputer; the input end of the single-chip microcomputer is connected with the infrared sensor, and the output end of the single-chip microcomputer is connected with the voice signal prompt unit, and the The power supply circuit unit is connected to one end of the patch switch, the other end of the patch switch is connected to the power supply terminal of the single-chip microcomputer, and the output terminal of the single-chip microcomputer is connected to the relay.

In this embodiment, the infrared sensor installed at the bottom right of the socket panel is very close to the bed, so it can monitor well whether there is anyone on the bed, and transmit the signal to the single-chip microcomputer for processing. The patch switch installed in the middle of the two jacks or the three jacks on the socket panel will be pressed by the plug to be closed when the plug is inserted into the jack, and the safety device controlled by the single-chip microcomputer is turned on. When the single-chip microcomputer gets the plug inserted into the jack and no one is present, it will drive the voice alarm unit to prompt to pull out the plug, and at the same time drive the relay to disconnect the socket power supply. When someone is present, the single-chip computer will drive the relay to connect the socket power supply. The patch switch on the socket panel is responsible for switching on and off the single chip microcomputer to complete the overall control of the device. The voice prompt unit is responsible for prompting the user not to forget to unplug the plug when leaving.

In summary, the utility model has strong usability, is easy to design, install and maintain, and has practical functions. When the user inserts the plug into the jack, the entire safety device is activated, and when the plug is pulled out, the entire device is closed, which effectively avoids fire hazards caused by long-term unmanned charging, and has a good promotion prospect.

The above-mentioned embodiment is only a description of the preferred embodiment of the present utility model, and is not intended to limit the scope of the present utility model. All variations and improvements should fall within the protection scope determined by the claims of the present utility model.
