The harvesters are machinery that integrates harvesting crops. You can also use artificial harvesting, rice, wheat and other crops in the field laying in the field, and then use grain harvesting machinery to pick up threshing. Harvesting rice, wheat and other cereal crops and straws crop harvesting machinery. Grain harvesting harvesters are developed on a variety of harvesting and thawing tools.
The traditional harvesters are dumb-type tools, in order to make the tool becomes intelligent, many businesses in the introduction of more features, comes with voice prompts intelligent harvesters, currently dedicated to the harvester voice program WT588DM01 voice module As well as WT588D16-28SS voice chip, are industrial-grade voice program.
The current intelligent harvester voice content is as follows:
1. boot welcome: welcome to use harvester products;
2. Turn or reach the end of the sound effect: drops of alarm sound;
3. When the barn has been stored full of tips: barn is full, please transfer grain to the warehouse;
4. When the harvester gasoline to a certain capacity prompted: lack of gasoline, please refuel;
5. harvester failure when prompted: product failure, easy maintenance;
WT588D voice module with the voice chip selection distinction is as follows:
Voice IC chip selection program: WT588D16-20SS
WT588D points are two, one is plug-in SPI WT588D-20SS, can support 2M ~ 32Mbit SPI-Flash memory; one is built-in SPI WT588D16-288S, this is only 16Mbit, some customers do not like to use two Chip, and choose to use a single chip can be considered WT588D16-28SS; intelligent cutting machine with WT588D this chip is mainly for voice content more, such as more than 80 seconds or more, in addition to repeat the replacement of voice, PWM Output can be directly driven 0.5W / 8Ω speaker, support DAC / PWM two output side; operating voltage DC2.8V ~ 5.5V; support load 6K ~ 22KHz sampling rate audio; support MP3 control mode, key control mode, 3 × 8 button Combination control mode, parallel port control mode, one-line serial port control mode, three-wire serial port control mode and three-wire serial port control I / O port expansion output mode.
Voice module program: WT588DM01
According to the plug-in or built-in SPI-Flash different playback time is different, support 2M ~ 32Mbit SPI-Flash memory; embedded DSP high-speed audio processor, processing speed; built-in 13Bit / DA converter, and 12Bit / Good sound quality; PWM output can directly promote the 0.5W / 8Ω speaker, push-pull current is abundant; support DAC / PWM two output; support MP3 control mode, key control mode, 3 × 8 key combination control mode, parallel port control mode, Serial control mode, three-wire serial port (see below) control mode and three-wire serial port control I / O port expansion output mode.
If you do not know which option to choose, you can consult with our online engineers to specify your specific program.
