Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings.

[0024] like figure 1 Shown, a kind of infrared remote control coding method comprises the following steps:

[0025] (1) Analyze the configuration file of the existing infrared remote control coding protocol. The existing infrared remote control coding protocol includes the NEC protocol, RC-5 / 6 protocol and SONY SIRC protocol, etc., and extract the protocol name, carrier frequency / Modulation frequency, duty cycle, logical bit, big and small endian, encoding type and repetition times Construct protocol attribute table in relational database, extract frame name, frame mode, frame reference, frame fixed length and frame fixed duration in configuration file Construct the protocol frame table in the relational database, extract the segment name, segment type, segment time sequence waveform, segment bit length, segment bit pattern, segment reference and segment code value i...

Abstract

The invention discloses an infrared remote coding method. The method comprises the following steps: (1) analyzing a configuration file of a conventional infrared remote coding protocol, constructing a protocol attribute table in a relational database, constructing a protocol frame table, and constructing a protocol segment table; (2) associating the protocol attribute table, the protocol frame table and the protocol segment table in the relational database; (3) transmitting a characteristic signal by pressing a key of a remote controller; (4) receiving the characteristic signal and transmitting a feedback signal by controlled equipment; (5) receiving the feedback signal by a coding unit and judging the infrared remote coding protocol to which the controlled equipment belongs according to the feedback signal; (6) receiving a command code transmitted by the key of the remote controller by the coding unit in the remote controller, constructing the configuration file by calling corresponding data in the protocol attribute table, the protocol frame table and the protocol segment table according to the infrared remote coding protocol to which the controlled equipment belongs, and coding according to the configuration file. The infrared remote coding method can be compatible with conventional different infrared remote coding protocols.

Description

technical field [0001] The invention relates to an encoding method, in particular to an infrared remote control encoding method. Background technique [0002] Infrared remote control is currently the most widely used means of communication and remote control. Because infrared remote control devices have the characteristics of small size, low power consumption, strong functions, and low cost, after color TVs and video recorders, infrared remote control devices are also used in other small electrical devices such as tape recorders, audio equipment, air conditioners, and toys. . In industrial equipment, in the environment of high voltage, radiation, toxic gas, dust, etc., the use of infrared remote control is not only completely reliable but also can effectively isolate electrical interference. [0003] In the communication between the infrared remote control and the controlled device, there is a communication protocol, that is, a communication rule, which is generally a one-...
