英语翻译
1.RF transmitter (something like remote control for car alarms) -
10000pcs for first order,in future (if project will have success up to
100000pcs).Low price solution is very important.Should send periodically (period is 1-2sec) his serial number (4bytes and up to 8bytes of another data received via UART (serial protocol with bitrate 300bytes/sec).
RF transmitting speed not less 19.2KBit/sec (more higher - better).
RF band 433,92Mhz,output power less 10mWt Power supply - 1pcs 1.5v(1.2v) AA
or 2-3 pcs of AAA battery.Transmitter should have low power consumption
(about less 20uA) from batteries during standby.Connector for external
power supply 5-12v.Case - plastic.No special requirements for design.Smaller,more light case is better.Connector for UART - 2.5mm stereo audioconnесtor.
2.USB RF transmitter+receiver (2000-3000pcs) in future up to 10000pcs.
Should receive information from RF transmitter (described above) from
distance up to 100-200m in open area in city conditions аnd send to
computer via USB interface.Also will be good to have ability to evaluate and send
to computer level of received RF sygnal.Should have ability to send data,received from computer.RF band 433,33Mhz,output power less 10mWt,bitrate 38-100kbit/sec.
Power supply from USB.Case - plastic.No special requirements for design.
3.Ethernet RF transmitter+receiver (1000pcs).
The same device like above but should be conncted to Еthernet (RJ45) port
directly and make ability to send received data to Internet directly without PC.
是一份客户的采购要求,不是很明白.433.92MHZ究竟是什么通信制式,我也不太明白.
1.射频发射机(类似汽车警报遥控)
- 首批订购10000件,将来如果项目成功,将有多达100000件订单.低价解决方案是很重要的.应能通过UART(通用异步收发器)周期性地(周期间隔为1-2秒)发送它的序列号(4字节)和能接收达8字节(如用每秒300kB的序列通信协议)
射频发送器速度不得低于每秒19.2kB(越高越好)
射频发送器波频433.92MHz,输出功率要不高于10mW - 用一颗 1.5V (1.2V)5号(AA)干电池,或2到3颗7号(AAA)干电池.
在待机状态(电源取自干电池)时,发送器功耗必须低(
