Summary of the invention
Technical matters to be solved by this invention is: at the defective that exists in the above-mentioned prior art, provide the clearance-type waking up method of the little wireless kilowatt meter reading-out system of a kind of power consumption of terminal.
The present invention is achieved like this:
A kind of clearance-type waking up method of wireless kilowatt meter reading-out system, microprocessor in the wireless acquisition terminal sends a pulse to the wireless telecommunications chip p.s., information acquisition register in the set wireless telecommunications chip, in monitoring time, judge whether to occur with the overlapping identical homogenous frequency signal of 470MHz frequency of operation, if there is not homogenous frequency signal, then the wireless telecommunications chip keeps dormant state; If homogenous frequency signal is arranged, the wireless telecommunications chip is promptly beamed back a response impulse to microprocessor, and microprocessor sends the instruction of quick wake on wireless communication chip, makes it enter duty.
If homogenous frequency signal is arranged, judge that immediately it is undesired signal or working signal.If working signal promptly enters normal operating conditions; If undesired signal, the CRC check that then reaches a hour are judged, if be judged as undesired signal, then take frequency hopping to handle, send instruction by microprocessor, make the wireless telecommunications chip operation in the 468.85MHz frequency range.
In each hour after frequency hopping is handled, all reach one minute CRC verification again, differentiate undesired signal and whether disappear; If disappear, then turn back on the 470MHz frequency that sets in advance and work; Otherwise the wireless telecommunications chip is still worked on the 468.85MHz frequency range.
The pulse width that microprocessor is issued the wireless telecommunications chip p.s. is 1 μ S, judges whether that the monitoring time that the homogenous frequency signal identical with frequency of operation occurs is 2mS.
Wireless acquisition terminal also can adopt secondary routing mode transmission signals, makes it possess second grade highway by pursuing the function of passing transmission signals.
The invention has the beneficial effects as follows:
The clearance-type waking up method of a kind of wireless kilowatt meter reading-out system of the present invention adopts the gap to wake the pattern of terminal up, having changed in the past, chip is waken up the mode that enters comprehensive duty repeatedly, the phenomenon of power consumption has been overcome, thereby guarantee to adopt powered battery,, the requirement of the long-term continuous working of low-power consumption.Frequency hopping function can be avoided co-channel interference; Waking up fast of terminal improved the speed of checking meter.The secondary routing function of wireless route acquisition terminal can thoroughly solve because the issuable communication of the riding position dead angle phenomenon of table tool.
Embodiment
When the wireless route acquisition terminal of " automated power rising " pattern of employing is in dormant state, microprocessor in the wireless route acquisition terminal sends an extremely short pulse p.s., as pulsewidth 1 μ S, give the wireless telecommunications chip, indivedual register set relevant with information acquisition in the wireless telecommunications chip are started, whether there is the homogenous frequency signal that sets in advance the about 2mS of its Looking Out Time to occur with monitoring.As there not being homogenous frequency signal, then the wireless telecommunications chip keeps dormant state in the Looking Out Time of this 2mS; If any homogenous frequency signal, the wireless telecommunications chip can be beamed back a response impulse to microprocessor at once, microprocessor is corresponding gives an order, quick wake on wireless communication chip, make it enter comprehensive duty, being normal receiving mode, receiving the same frequency data, is that central processing unit judges whether these data are useful by System Control Center then.Thus, wakeup time is faster nearly five times than normal mode in real time.
The wireless transmission frequency of wireless route acquisition terminal is 470MHz, be subjected to co-channel interference influence after, automatic frequency-hopping is to 468.85MHz.
Concentrator is transferred to remote control center to after carrying out respective handling from the data of wireless route acquisition terminal by GPRS; Also can data be copied and get in the write by hand device, and then import in the computer system of control center through wireless transmission.
When suffering from the 470MHz co-channel interference, following several situation can take place: system produces unnecessary operation; Copy when copying and accepting parameter less than or miscopied; During interference by the random thoughts current power dissipation of false wake-up be under the normal condition 6-7 doubly.For this reason, wireless route acquisition terminal carries out CRC check: increase before each string work order and set special differentiation character string, earlier this is set character string before instruction of the every acceptance of the microprocessor of wireless route acquisition terminal and carry out CRC check, as differentiation be confirmed to be co-channel interference but not the instruction after, promptly disturb accumulative total.Microprocessor each hour of wireless route acquisition terminal be altogether to the wireless telecommunications chip starting impulse that to send 3600 pulsewidths be 1 μ S, detects as accumulative total to reach 2700 times for the 470MHz co-channel interference but not instruction, and promptly frequency hopping changes the work of 468.85MHz frequency range over to; Co-channel interference accumulative total does not reach 2700 times therebetween, and the frequency hopping instruction does not just take place, and microprocessor changes the next round monitoring periods over to.
If any the contact of write by hand device, can reflect disturbed condition on the write by hand device during the frequency hopping, the also corresponding commentaries on classics frequency of write by hand device to 468.85MHz frequency band and acquisition terminal contact checked meter.
In each hour after frequency hopping takes place, wireless route acquisition terminal is differentiated once automatically, promptly carries out CRC check, and the 470MHz band information is reached one minute differentiation with the frequency sign indicating number, disappear as disturbing frequently, wireless route acquisition terminal returns dominant frequency 470MHz work automatically; Otherwise still staying the 468.85MHz frequency range escapes disaster.
The present invention can produce by using for reference this paper disclosure all combinations and method open and that disclose, although combination of the present invention and method are described by detailed implementation process, but those skilled in the art obviously can be spliced the described method and apparatus of the application in not breaking away from content of the present invention, spirit and scope or change, or increase and decrease some parts, more particularly, the replacement that all are similar and change apparent to those skilled in the artly, they are regarded as being included among spirit of the present invention, scope and the content.
