Abstract
The utility model relates to a multifunctional key reminding device, which mainly solves the problem that people forget to take keys and forget to take back the keys after opening doors so as to bring inconvenience to life. The multifunctional key reminding device is characterized in that the device also comprises a middle-distance radio frequency card reader, two TX05D reflective infrared switches, an SC010B voice chip and a loudspeaker, wherein the card reader is connected with a singlechip through an RS232 interface; the switch is connected with a PA port of the singlechip; the voice chip is connected with the PA port of the singlechip; and an audio signal input end of the loudspeaker is connected with an audio signal output end of the voice chip. The key reminding device disclosed by the utility model can determine whether a person forgets to take keys and give corresponding voice prompts according to the judgment results of an infrared correlation system and the card reader.
Description
Technical field
The utility model relates to the alarm set in a kind of people's of being applied to daily life.
Background technology
Key is one of people's article that all will use every day, and much human all can run into to go out forgets the problem of regaining key after leaving behind key and opening the door, and this brings a lot of inconvenience for life of people.Mostly existing key reminiscences is the reminds people band key of going out, and has but ignored the reminds people back of opening the door and has regained key.Simultaneously existing key reminiscences equipment constitutes complicated; And cost is higher, be difficult for to popularize, and therefore needs a kind of band key of can not only reminds people going out; And the back of can reminds people opening the door regains key, simultaneously the small and exquisite Key with alarm attractive in appearance and with low cost of outward appearance.
Summary of the invention
The technical matters of mentioning in order to solve in the background technology; The utility model provides a kind of multi-functional Key with alarm; Whether the multi-functional Key with alarm of this kind can leave behind key to people according to the judged result of infrared correlation system and radio-frequency card reader and provide the relevant voice prompting, and has the small and exquisite characteristics attractive in appearance and with low cost of outward appearance.
The technical scheme of the utility model is: the multi-functional Key with alarm of this kind, comprise a STM8L101 single-chip microcomputer, and in addition, said device also comprises a middle distance radio-frequency card card reader, said card reader is connected with said single-chip microcomputer through the RS232 interface; Comprise 2 reflective infrared switches of TX05D, said switch is connected in the PA port of single-chip microcomputer; Comprise a SC010B speech chip, said speech chip is connected in the PA mouth of single-chip microcomputer; Comprise a loudspeaker, the audio signal input end of said loudspeaker is connected in the audio signal output end of said speech chip.
The utlity model has following beneficial effect: utilize the multi-functional Key with alarm of this kind with 2 reflective infrared switches of TX05D, promptly No. 1 infrared correlation pipe and No. 2 infrared correlation pipe levels are installed on the doorframe, go out and enter direction with judgement.If the people gos out through being judged as through No. 2 infrared correlation pipes behind No. 1 infrared correlation pipe earlier, otherwise, earlier through behind No. 2 infrared correlation pipes through No. 1 infrared correlation pipe for entering.Through the radio-frequency card card reader of on doorframe, installing, can discern on the key the radio-frequency card of installing, to distinguish whether people have key on one's body when entering and going out.Judge by single-chip microcomputer and to be controlled at the loudspeaker pronunciation of installing on the doorframe behind the result, can determine whether to provide relevant voice according to the judged result of infrared correlation system and card reader and point out.In addition, this kind alarm set is because simple in structure so that outward appearance can be done is very small and exquisite attractive in appearance, and owing to adopted the STM8L101 single-chip microcomputer, therefore has characteristics with low cost, has stronger practicality.
Description of drawings:

Fig. 2 is that the utility model is installed in the structural representation on the doorframe.
Fig. 3 is fixing the structural representation behind the radio-frequency card on the key.
1-loudspeaker among the figure, 2-middle distance radio-frequency card card reader, 3-1 number infrared correlation pipe, 4-2 number infrared correlation pipe, 5-key, 6-radio-frequency card.
Embodiment:
Below in conjunction with accompanying drawing the utility model is described further:
By shown in Figure 1; The multi-functional Key with alarm of this kind; Comprise a STM8L101 single-chip microcomputer, its unique distinction is: said device also comprises a middle distance radio-frequency card card reader, and the Card Reader distance is 2-3m; Single-chip microcomputer can be provided with and read Card Reader information to it, and said card reader is connected with said single-chip microcomputer through the RS232 interface; Comprise 2 reflective infrared switches of TX05D, said switch is connected in the PA port of single-chip microcomputer, the reflective infrared switch of this kind, and maximum inspection distance is 1.2m, appears at as object and detects in the distance, when promptly reflective distance diminished, TX05D exported high level signal; Comprise a SC010B speech chip, said speech chip is connected in the PA mouth of single-chip microcomputer, and this chip sectional recording can be recorded 32 sections language at most, and total voice time is 10 seconds.Can record two sections information of voice prompt in this equipment; Comprise a loudspeaker, the audio signal input end of said loudspeaker is connected in the audio signal output end of said speech chip.
During use, as shown in Figure 2, entire equipment is installed on the doorframe; Height is about 1m; About normal person's waist scope, as shown in Figure 3 greatly, fasten a radio-frequency card 6 on the key 5; Two TX05D must level be installed, judge according to the order of two TX05D output high level and enter or go out.Promptly No. 1 infrared correlation pipe 3 and No. 2 infrared correlation pipe 4 levels are installed on the doorframe, go out and enter direction with judgement.If the people gos out through being judged as through No. 2 infrared correlation pipes behind No. 1 infrared correlation pipe earlier, otherwise, earlier through behind No. 2 infrared correlation pipes through No. 1 infrared correlation pipe for entering.To distinguish whether people have key on one's body when entering and going out.The voice broadcasting system of installing on the doorframe can determine whether to provide the relevant voice prompting according to the judged result of infrared correlation system and card reader; When having detected the people through out-of-date; At first carry out Card Reader through card reader; If read radio-frequency card information, key is described on the person, do not need voice suggestion.If do not read radio-frequency card information, explain when going out, to leave behind key or forget and pull up key that the direction of judging according to the TX05D signal then of entering or go out provides the different voice prompting when entering.Promptly go out and report " please check and whether be with key " when leaving behind key, enter and forget report " please check whether key is pulled up " when pulling up key.
