On-off device and control realization method thereof

Abstract

The invention discloses an on-off device and a control realization method thereof. The method includes the steps that a control audio frequency with specific audio frequency attributes is detected, and acoustic-electric conversion processing is conducted on the control audio frequency to obtain a specific impulse sequence; matching is conducted on the specific impulse sequence and a preset on-off control impulse sequence, and whether an on-off control signal is output to a controlled electric appliance or not is selected according to a matching processing result. In the on-off device and the control realization method of the on-off device, a user can use clapping sound or other control audio frequencies with specific audio frequency attributes to achieve on-off control of controlled electric appliances; in the specific realization process, the voice recognition technology and an unconventional voice operated switch do not need to be used, and the on-off device and the control realization method of the on-off device have multiple advantages of being high in identification, high in reliability, high in adaptability and low in cost.

Description

technical field [0001] The invention relates to the technical field of switches, in particular to an acousto-optic controllable switch device and a control realization method thereof. Background technique [0002] Usually, mechanical manual switches are commonly used for light control in public places of schools, institutions, factories and mines, and public corridors in residential areas. However, in actual use, since the mechanical manual switch needs to be manually toggled frequently, the damage rate of this type of switch is very high, which not only increases the amount of maintenance, wastes money, but also tends to cause accidents. Moreover, during the use of this type of switch, it is easy to forget to turn off the lights due to the negligence of the user, so that many lamps are on for a long time, which not only shortens the life of the lamps, but also wastes energy consumption. , Units, and individuals have caused considerable economic losses. [0003] And with t...

Problems solved by technology

Its disadvantage is that: for the sound and light control switch, external noise can also trigger the light to be turned on, and in practical applications, it can only use the delay circuit to delay the control of turning off the light. After the light is turned off, it must be restarted To control the lights to turn on, you need to recreate the corresponding sound to trigger the turn on

[0014] 1. The cost is high, so the market share of this type of lamp control switch is extremely low, and it is overkill;

[0015] 2. Speech recognition needs to be "trained" to increase the complexity of use, and only "trained" voices can be recognized during use, and the versatility is poor;

[0016] 3. As far as self-adaptation is concerned, it needs further improvement. It is still affected by specific people, accents or dialects, as well as environmental noise, noise, and speaking voices, and the recognition rate is not high;

[0017] 4. The language model currently used is only a probabilistic model, and the grammar model based on linguistics has not been used, which cannot realize the recognition of continuous language
