Remote control infrared learning based on zigbee technology

After confirming that the ZigBee network is connected properly, open the wireless sensor training platform software, click the "Start System" button, and all sensors waiting for infrared learning go online. Switch to the "Device Control" tab, you can see the basic information of the node, information acquisition window and various control buttons.

Turn on the switch on the side of the coordinator to start the work of the coordinator, open the wireless sensor network experimental platform software, infrared learning. Select the port number displayed in the PC Device Manager at the serial port number, change the MAC address, and set the number of the board for the appliance control device; click the “Learning” button in the infrared learning module, and the node board will perform infrared reception learning and complete the general remote control. The infrared decoding and parsing function of the device, and the infrared transmitter lamp light means that the learning is successful; clicking the "emission" button, the infrared signal transmitter of the node board can control the home appliance by sending the infrared signal of the home appliance.

Home appliances control system TV, air conditioning, DVD equipment, the node board to install infrared control board expansion components, in the fixed installation, the infrared transmitter should be aligned with home appliances, by learning the corresponding remote control device signals to achieve the infrared system Learn to control all home appliances.

Infrared simple emission and reception principle: At the transmitter, the input signal is amplified and transmitted to the infrared transmitter. After the receiver receives the infrared signal, it is amplified by the amplifier and then converted to a signal.

The infrared learning module manages and controls the infrared appliances centrally through the infrared device control center, and is mainly divided into a main controller end, a wireless communication module, and an infrared centralized control module, which can realize centralized control of indoor infrared devices such as DVDs and televisions. The wireless communication module is a wireless transceiver based on the single-chip microcomputer and realizes the communication between the main controller end and the infrared home appliances. Infrared centralized control module realizes intelligent learning of infrared remote controller encoding, infrared signal reception and transmission.

The host computer is mainly responsible for implementing the control of the entire system. It sends infrared data to the infrared learning module to realize infrared learning and infrared control commands. First, the host computer sends the learning command data to the infrared learning module through the wireless serial port, and then the infrared learning module can begin to learn the infrared remote control device. After learning, the infrared module starts to save the learned infrared data and feeds it back to the upper computer. The upper computer can then issue a control command to the infrared learning module to achieve the control of the home infrared system.
