Detailed Description
The invention is further described with reference to the following figures and examples.
Referring to fig. 1 and 2, in the infrared remote control learning circuit and the learning method, an infrared remote control learning circuit is arranged in a controlled object (such as an individual control switch module, an electric lamp, a television, a fan, a humidifier and the like), the infrared remote control learning circuit comprises a microcomputer processor and infrared receiving heads, a storage module and an output module which are respectively connected with the microcomputer processor, and the infrared remote control learning circuit learns through the following steps:
the method comprises the following steps: the infrared receiving head receives an infrared signal of an original remote controller or a non-original remote controller and transmits the infrared signal to the microcomputer processor, and the microcomputer processor obtains a sequential time logic relationship of key values and key values after decoding through infrared signal software;
step two: the key value is compared with a key value table in the storage module for query, when the key value table contains the received key value, the microcomputer processor sends a corresponding control action instruction (such as switching action, air volume regulation, fog volume regulation and the like) to the output module according to the key value, and when the key value table does not contain the received key value, the third step is carried out;
step three: comparing the key value sequence time logic relationship preset by the microcomputer processor with the received key value sequence time logic relationship, when the key value sequence time logic relationship is matched with the received key value sequence time logic relationship, updating the corresponding old key value on the replacement key value table by the new key value, and when the key value sequence time logic relationship is not matched with the received key value sequence time logic relationship, finishing learning;
the control object applying the learning circuit and the learning method provided by the invention can be matched with any remote controller, and under the conditions that a universal remote controller is not used and the controlled object does not need to be touched, when the original remote controller is damaged or lost, the remote control function of the controlled object can still be kept, so that the controlled object can adapt to various different non-original remote controllers.
Furthermore, the infrared remote control learning circuit further comprises a key and an indicator light module, and operation by a user is facilitated.
Furthermore, the storage module is a power-down memory, an additional power supply does not need to be provided for the storage module, and the overall structure of the circuit is simplified.
Furthermore, the power-down memory storage is an independent chip, and can be matched with independent chips with different storage amounts according to actual needs or integrated in a microcomputer processor, so that the whole structure of the circuit is more compact.
Further, referring to fig. 3, the logical relationship of the sequence time of the key values is a value of the number of times of receiving the same key value in a unit time, for example, the B1 key on the unaligned remote controller is continuously pressed for 10 times (the key interval does not exceed 1 second), the microcomputer processor updates the key value table, so that the B1 key replaces the a1 key on the unaligned remote controller, at this time, the B1 key on the unaligned remote controller can realize the function of the a1 key corresponding to the remote controlled object, and so on, and finally the unaligned remote controller completely replaces all the key functions of the unaligned remote controller.
Further, referring to fig. 4, the logical relationship of the key value sequence and time is the value of the number of times of receiving the same sequence of key value combinations in a unit time, for example, continuously (the key interval does not exceed 1 second) pressing the B1, B2, and B3 keys 3 times (B1-B2-B3, B1-B2-B3, B1-B2-B3) on the unaligned remote controller, and after the microcomputer processor receives 3 regular key value combinations, the microcomputer processor updates the key value table, and finally realizes that the unaligned remote controller completely replaces all the key functions of the unaligned remote controller.
