Abstract
The utility model discloses an ultrasonic alarm, comprising an ultrasonic transmitting circuit, an echo signal receiving circuit, a microcontroller MCU, an LDC display, an alarm circuit and a power source. An input terminal of the microcontroller MCU is respectively connected with the ultrasonic transmitting circuit and the echo signal receiving circuit, and an output terminal of the microcontroller MCU is respectively connected with the LDC display and alarm circuit. The ultrasonic alarm of the utility model can be conveniently arranged to a socket, a household electrical appliance and a dangerous article or a dangerous region in a house. Through such an alarm, when a child gets close to the dangerous article or the dangerous region in the house, voice prompts can be provided by the alarm.
Description
Technical field
The utility model relates to a kind of alarm, relates in particular to the ultrasound wave alarm of a kind of children of preventing near dangerous goods or danger zone.
Background technology
In each family, child is most important member in the family, and safety in the nurse process to child, how to guarantee child is the problem that a lot of families extremely pay close attention to.A lot of children is because nurse improper appearance electric shock, scald, tumble injury even incident such as fall down from the building; The suffered injury of child has brought huge misery for the family at place; The utility model is invented a kind of hyperacoustic alarm under this background; Can be positioned over the article or the dangerous area that possibly damage child, when child near the time alarm send chimes of doom and remind child and nurse personnel to arouse attention, thereby suppress the generation of unscheduled event.
Summary of the invention
The utility model technical matters to be solved is to existing technological deficiency, provides a kind of near dangerous goods and area (like supply socket, kitchen, balcony etc.) audio alert apparatus.
The utility model adopts following technical scheme for solving the problems of the technologies described above:
A kind of ultrasound wave alarm comprises ultrasonic transmit circuit, echoed signal receiving circuit, microcontroller MCU, LCD display, warning circuit, power supply; Wherein ultrasonic transmit circuit, echoed signal receiving circuit are connected with the input end of microcontroller MCU respectively, and the output terminal of microcontroller MCU is connected with LCD display, warning circuit respectively.
Preferably, the ultrasound wave alarm of the utility model, ultrasonic transmit circuit adopts ultrasound transmitting transducer TCT40-16T, and the echoed signal receiving circuit adopts ultrasound wave receiving transducer TCT40-16R.
Preferably, the ultrasound wave alarm of the utility model, microcontroller MCU adopts the MC68HC705J1AJ of motorola inc Series MCU.
Preferably, the ultrasound wave alarm of the utility model, LCD display adopts the TFT LCD.
Preferably, the ultrasound wave alarm of the utility model, warning circuit adopts hummer or speech chip.
Preferably, the ultrasound wave alarm of the utility model, power supply employing+5V battery or stabilized voltage supply.
The utility model adopts above technical scheme compared with prior art, has following technique effect:
The utility model can be installed in dangerous goods or the danger zone in socket, household electrical appliance and the family easily; Can realize as child during through such alarm apparatus near dangerous goods in the family or danger zone; Alarm sends voice prompting function, can warn child on the one hand, can remind nurse child's adult on the other hand; In time to take the corresponding protection measure, avoid accidents.
Description of drawings
Fig. 1 is the utility model system architecture synoptic diagram.
Embodiment
Below in conjunction with accompanying drawing the technical scheme of the utility model is done further detailed description:
As shown in Figure 1, the utility model comprises ultrasonic transmit circuit, echoed signal receiving circuit, microcontroller MCU, LCD display, warning circuit, power supply; Wherein ultrasonic transmit circuit, echoed signal receiving circuit are connected with the input end of microcontroller MCU respectively, and the output terminal of microcontroller MCU is connected with LCD display, warning circuit respectively.
Ultrasonic transmit circuit adopts ultrasound transmitting transducer TCT40-16T; The echoed signal receiving circuit adopts ultrasound wave receiving transducer TCT40-16R; Microcontroller MCU adopts the MC68HC705J1AJ of motorola inc Series MCU; LCD display can adopt common TFT LCD, and warning circuit can adopt hummer or speech chip, and power supply can adopt+5V battery or stabilized voltage supply.
Ultrasound wave is meant the mechanical Sasser that in elastic medium produce of frequency greater than 20 kHz, and therefore characteristics such as directive property is strong, energy consumption is slow, propagation distance is far away relatively that it has often are used to non-contact distance-measurement.Because ultrasound wave is insensitive to light, color and electromagnetic field, so ultrasonic ranging has adaptive faculty preferably to environment, and ultrasonic measurement also can obtain well compromise in real-time, precision, price in addition.
The ultrasonic transmit circuit of the utility model partly is in order to let ultrasonic transmit circuit send the square-wave pulse signal about 40kHz to the external world.The generation of the square-wave pulse signal about 40 kHz is realized through software programming by microcontroller MCU; In air, propagating of the ultrasonic ratio that above-mentioned ultrasonic transmit circuit is launched; Running into barrier will return; The echo receiving circuit partly is for reflection wave (echo) is received smoothly and changes; Become electric signal; Then this electric signal is amplified, obtains a negative pulse after the processing such as filtering, shaping and give microcontroller MCU, by microcontroller MCU according to ultrasound wave from time of being transmitted into reflection process and corresponding testing algorithm calculate when forefathers' (or other object) to article that are installed in or place, when distance reaches alarm range, drive warning circuit and send alarm by microcontroller MCU.Simultaneously, the concrete numerical value of distance is presented on the LCD display, and power supply is the total system power supply.
The utility model institute alarm designed can be installed in article or the area that socket, household electrical appliances, balcony etc. possibly damage to children, can be set to 0.1 ~ 0.5m by alarm distance, also can set as required.When child near the time send prompting by warning circuit, when reminding child, also cause the head of a family's attention.
