Description
Technical field
The utility model relates to daily living article, particularly a kind of infrared intelligent key ring with automatic prompting function.
Background technology
In life, floor administrative staff manage multiple door in building, need to search key one by one when enabling.In order to the convenience of opening the door, some building pipe is labelled one by one and converge on a key ring by all keys.But this method still wastes time and energy, because need to search label one by one when opening the door, just key can be found after comparison one by one.And label on the key also may occur stained, it is unclear to become identification, thus brings and search inconvenience.
Utility model content
The utility model, for solving above-mentioned the deficiencies in the prior art part, proposes a kind of infrared intelligent key ring of concrete automatic prompting function, to searching rapidly corresponding key, thus improves search efficiency, time saving and energy saving.
The utility model technical solution problem adopts following technical scheme:
The design feature of a kind of infrared intelligent key ring of the utility model be with the infrared launcher be arranged on several doors with the use of; The composition of described infrared launcher comprises: the first single-chip microcomputer, infrared transmitting circuit, the first power switch circuit and the first relay indicating light;
Described key ring is provided with infrared receiving device; The composition of described infrared receiving device comprises: second singlechip, infrared receiving circuit, second source on-off circuit and the second relay indicating light;
Described key ring is provided with several key chains, each key chain hangs with key and correspond to a LED light;
Described infrared launcher connects the power supply of described first single-chip microcomputer and infrared transmitting circuit by described first power switch circuit, and lights the first relay indicating light; Infrared transmitting circuit described in described first Single-chip Controlling launches infrared signal to described infrared receiving device;
Described infrared receiving device connects the power supply of described second singlechip, infrared receiving circuit and buzzer circuit by described second source on-off circuit, and light the second relay indicating light, described second singlechip controls described infrared receiving circuit and receives described infrared signal, and the LED light lighted on corresponding key chain, with the door at the key operated corresponding infrared launcher place at described LED light turned-on position place.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, the utility model makes full use of the features such as the easy compatibility of infrared communication technique, low-angle (within 30 °), short distance, the transmission of point-to-point straight-line data and strong confidentiality, key ring devises infrared receiving device, door devises infrared launcher, utilize infrared receiving device can find rapidly the room key corresponding to infrared signal that corresponding door is launched, thus decrease the time of looking for key to open the door, bring facility, there is good Consumer's Experience.
2, the utility model adopts single-chip microcomputer and the infrared communication technique of low cost, has greatly saved design cost, meanwhile, by the expanded function of single-chip processor i/o mouth, can increase the number of enabling key easily, favorable expandability.

Detailed description of the invention
In the present embodiment, a kind of infrared intelligent key ring be with the infrared launcher be arranged on several doors with the use of; A set of infrared light emission device each door is equipped with, as shown in Figure 2, the composition of infrared launcher comprises: the first single-chip microcomputer, the infrared transmitting circuit including transistor drive circuit and infrared-emitting diode, the first power switch circuit and the first relay indicating light; Power supply in first power switch circuit connects the first single-chip microcomputer, infrared transmitter and the first relay indicating light; In concrete enforcement, the first single-chip microcomputer adopts the STC89C52 single-chip microcomputer of STC Corporation;
As shown in Figure 3, key ring 1 is provided with infrared receiving device; The composition of infrared receiving device comprises: second singlechip, infrared receiving circuit, second source on-off circuit, buzzer circuit and the second relay indicating light; The power supply of second source on-off circuit connects second singlechip, infrared light receiver, buzzer circuit and the second relay indicating light; In concrete enforcement, adopt plastic packaging integration infrared receiver HS0038, its volume is little, it is a kind of integrated circuit integrating infrared receiver, amplification, shaping, without any need for outward element, just can complete from infrared receiver to work such as outputs, be suitable for various infra-red remote control and Infrared data transmission.
As shown in Figure 1, key ring 1 is provided with several key chains 2, each key chain 2 hangs with key 3 and correspond to a LED light 4; There is provided 8 paths of LEDs indicator lamps at present, the key of ALARA Principle 8 doors; Maximumly provide 28 paths of LEDs indicator lamps, the key of ALARA Principle 28 doors; If set up expansion module, then can increase management key quantity.
The course of work of the present utility model is as follows:
When needing to open door, infrared launcher connects the power supply of the first single-chip microcomputer and infrared transmitting circuit by the button in the first power switch circuit, and lights the first relay indicating light; First single-chip microcomputer promotes infrared-emitting diode after being amplified to certain power by the triode that the code signal of number to be sent to infrared transmitting circuit by I/O port and launches infrared signal to infrared receiving device.
Infrared receiving device connects the power supply of second singlechip, infrared receiving circuit and buzzer circuit by the button in second source on-off circuit, when button is pressed, buzzer " drips " sound with explanation, and light the second relay indicating light, prompting user is current is mode of operation, second singlechip controls infrared receiving circuit and receives infrared signal, obtain current number thus the LED light on corresponding key chain is lighted, with the door at the key operated corresponding infrared launcher place at LED light turned-on position place.When again pushing button, buzzer " drips " sound and enters park mode to point out second singlechip, and the LED light on key ring is all extinguished.Next time pushes button and again can enter mode of operation when using, thus can iterative cycles work.
