技术领域technical field
本发明涉及通信领域，尤其涉及一种实现超低功耗的通信方法、通信装置及通信系统。The invention relates to the communication field, in particular to a communication method, a communication device and a communication system for realizing ultra-low power consumption.
背景技术Background technique
现有技术中无线模块通过检测同步字唤醒休眠模式下的设备来实现设备的低功耗，该技术利用无线模块的自动唤醒功能和同步字检测中断来唤醒无线通信系统。无线通信设备在不需要发送和接收数据的空闲模式处于休眠模式，休眠时在设定的时间周期内的唤醒模块的接收通过检测同步字来查看是否有数据需要接收。如果在唤醒的时间内侦测到同步字，认为有数据需要接收，唤醒无线通信芯片彻底进入工作模式；如果在唤醒的时间内没有侦测到同步字，则认为没有要接收的数据，再次进入休眠模式，等待下一周期的唤醒；这样通信模块在不需要数据传输时大部分时间都处于休眠模式，来降低的功率的消耗。但是对于对功耗特别敏感的设备(如仅使用电池供电)，功耗仍然过高。并且使用同步字的检测来确认是否有需要接收的数据，那么至少需要接收完同步字，那么需要的时间有：休眠模式唤醒到接收模式的时间+接收引导码的时间+接收同步字的时间，从休眠模式直到确认是否有接收需要的时间较长，相应的消耗的功耗就较大，对于某些仅能使能电池功能的设备，限制了设备的使用寿命。In the prior art, the wireless module realizes the low power consumption of the device by detecting the synchronization word to wake up the device in the dormant mode. This technology utilizes the automatic wake-up function of the wireless module and the synchronization word detection interrupt to wake up the wireless communication system. The wireless communication device is in the sleep mode in the idle mode that does not need to send and receive data. During sleep, the wake-up module receives within the set time period by detecting the synchronization word to check whether there is data to be received. If the synchronization word is detected within the wake-up time, it is considered that there is data to be received, and the wireless communication chip is awakened to enter the working mode completely; if the synchronization word is not detected within the wake-up time, it is considered that there is no data to be received, and enter again Sleep mode, waiting for the wake-up of the next cycle; in this way, the communication module is in sleep mode most of the time when no data transmission is needed, so as to reduce power consumption. But for devices that are particularly sensitive to power consumption (such as using only battery power), the power consumption is still too high. And use the detection of the synchronization word to confirm whether there is data to be received, then at least the synchronization word needs to be received, then the required time is: the time to wake up from the sleep mode to the receiving mode + the time to receive the boot code + the time to receive the synchronization word, It takes a long time from sleep mode to confirm whether there is reception, and the corresponding power consumption is relatively large. For some devices that can only enable the battery function, the service life of the device is limited.

可以理解的是，本发明技术方案降低功耗举例说明：It can be understood that the technical solution of the present invention reduces power consumption with an example:
部分参数如下：Some parameters are as follows:
设定的时间周期为5s；The set time period is 5s;
A原技术方案需要的功耗A The power consumption required by the original technical solution
休眠模式唤醒到接收的时间+接收5byte引导码的时间+接收2byte同步字的时间：Sleep mode wake-up to receive time + time to receive 5byte boot code + time to receive 2byte sync word:
0.8ms+1000*(5+2)*8/9600ms＝6.633ms0.8ms+1000*(5+2)*8/9600ms＝6.633ms
休眠模式下的功耗是1uA，接收功耗是14mAPower consumption in sleep mode is 1uA, receiving power consumption is 14mA
现有技术下，空闲模式每秒的功耗是：Under the existing technology, the power consumption per second in idle mode is:
(14mA*6.633ms+0.001mA*4994.167)/5＝19.57uA(14mA*6.633ms+0.001mA*4994.167)/5＝19.57uA
B本发明技术方案需要的功耗B the power consumption that technical solution of the present invention needs
休眠模式唤醒到接收的时间：0.8msSleep mode wake-up to receive time: 0.8ms
故无线芯片空闲模式下每秒的功耗是：Therefore, the power consumption per second of the wireless chip in idle mode is:
(14mA*0.8ms+0.001mA*4994.167)/5＝3.24uA(14mA*0.8ms+0.001mA*4994.167)/5＝3.24uA
相较于已有技术的每秒消耗19.57uA的功耗，新技术降低的功耗19.57/3.24＝6.04倍，极大的降低的无线芯片的功耗，可用于仅适用电池供电的设备(如故障指示器)，延长设备到原来6倍的待机寿命。Compared with the power consumption of 19.57uA per second in the existing technology, the power consumption reduced by the new technology is 19.57/3.24=6.04 times, which greatly reduces the power consumption of the wireless chip, and can be used for devices that are only suitable for battery power (such as fault indicator), extending the standby life of the device to 6 times the original.
