Embodiment
As shown in Figure 1, a kind of wireless searching positioner based on wireless awakening technology comprises:
The wireless transmit/receive units 2 that is connected with antenna 1;
What link to each other with wireless transmit/receive units 2 wakes timer 4 up, is used to wireless transmit/receive units 2 that the timing wake-up signal is provided;
The decision logic circuit 3 that links to each other with wireless transmit/receive units 2 is used to judge the whether correct of data that wireless transmit/receive units 2 receives from antenna 1, if correctly then data are sent to microprocessor (MCU) 5;
Wherein, the described timer 4 that wakes up is connected with microprocessor 5, wakes timer 4 up by 5 pairs of described microprocessors and carries out the time setting.
Wherein, also comprise power module 6, described power module 6 with wireless transmit/receive units 2, decision logic circuit 3, wake timer 4 up, microprocessor 5 is connected and provide electric power for it.The described power module 6 of stating can adopt battery, conveniently to carry.Wherein, decision logic circuit 3 can adopt field programmable gate array (FPGA, Field-programmable gate array) circuit.
As shown in Figure 2, also comprise a shell, described power module 6, wireless transmit/receive units 2, wake timer 4, decision logic circuit 3, microprocessor 5 up and place in this shell.In addition, antenna 1 can adopt built-in aerial, and is built in this shell.
Wherein, indicator light 7 on the described shell and button 8, described indicator light 7 links to each other with microprocessor 5 with button 8.
Wherein, described wireless transmit/receive units 2, decision logic circuit 3, wake timer 4 up and be integrated in the integrated circuit.
Very simple to the operation that present embodiment provides based on the wireless searching positioner of wireless awakening technology, by a button 8 and an indicator light 7 on the panel, can set that button is motionless to be normality, and be in the reception response status; For searching call state, can launch wireless paging signals and wait for the reception answer signal when button 8 is pressed.
During use, adopt above-mentioned two wireless searching positioners based on wireless awakening technology, for searching calling set, another is for receiving transponder with one of them.It is in full accord with reception transponder structure to search calling set, by function button 8 its working methods of decision.Usually be in resting state during as the reception transponder, during search, its course of work is as follows:
1) searches calling set and initiatively send wireless paging signals;
2) after the reception transponder was waken up by wireless paging signals, call signal had been received in glittering its indicator light 7 expressions;
3) receive transponder and return an answer signal to pursuit airplane;
4) pursuit airplane is received glittering indicator light 7 behind the answer signal, and expression is received and replied.
In the above-mentioned course of work, if the rescue worker pushes button 8, indicator light 7 is glittering, then represent by searching target in the communication distance scope, otherwise target is not in search area.
For power consumption is reduced as much as possible, the wireless searching positioner that present embodiment provides based on wireless awakening technology, on hardware, adopt the energy consumption heterarchical architecture, as shown in Figure 3, wireless transmit/receive units 2, wake that to decide device device 4 be the first energy consumption layer up, FPGA decision logic circuit 3 is the second energy consumption layer, and microprocessor 5 is the 3rd energy consumption layer.Wherein, wireless transmit/receive units 2 comprises radio frequency (RF) transceiver module, signal strength detector (RSSI), decides device device 4 and periodically wakes up and intercept wireless channel whether call signal is arranged by waking up.RSSI can be used to the interference signal that filtered signal intensity is lower than set point, thereby reduces unnecessary reviving to save electric energy.Because radio frequency (RF) transceiver module, signal strength detector (RSSI) are prior art, therefore omit detailed description to this part.Energy consumption hierarchical control flow process specifically describes as follows as shown in Figure 4:
1) wakes timer timing wake-up wireless transmit/receive units up, the radio frequency of wireless transmit/receive units (RF) transceiver module received signal judges that through field intensity detector (RSSI) this signal is enough strong, when having surpassed the thresholding of setting, then wake the FPGA decision logic circuit of the second energy consumption layer up, enter step 2); Otherwise step 1) is changeed in filtering;
2) whether FPGA decision logic circuit judges frame structure is eligible, if not the information frame that oneself will receive is then abandoned receiving and continued sleep, changes step 1); If decision logic circuit judges frame structure is eligible, then after the decision logic processing of circuit, wake the MCU of the 3rd energy consumption layer up;
3) MCU is for further processing to the data of receiving.The MCU power consumption of a new generation has been done very lowly, and there is the energy consumption control logic its inside, can not enter park mode when each functional module is not worked.
In the present embodiment, can adopt the wireless communication module and the wireless awakening agreement of 433MHz frequency range, the data frame format of transmission is as shown in the table:
| Lead code | Synchronization character (32bit) | Address (8bit) | Data field (8bit) | CRC check (16bit) |
The transmitting-receiving sequential chart of wireless awakening as shown in Figure 5, effectively time of reception t_RX must be greater than the frame period time T 1 that sends signal, otherwise receiver may be missed the frame that will receive.And T1 be by TX send wake Frame duration TX up and free time (IDEL) duration determines.
When receiver is waken up, if in the t_RX time slot, do not find effectively to search frame, then enter sleep again, shown in the A moment among Fig. 5 at once.If find effectively to search frame in the t_RX time slot, and data receive that all then sleep at once just finishes in the time of need not waiting t_RX to be all over, as B among Fig. 5 constantly shown in, B1 is possible RX time-delay among the figure.If find effective frame in the t_RX time slot, data did not also harvest when t_RX was all over, and then must wait until just to enter sleep after all receiving, and shown in the C moment, C1 is that RX extends to the TX postamble among the figure.
Above-described embodiment only is used to illustrate technological thought of the present invention and characteristics, its purpose makes those skilled in the art can understand content of the present invention and is implementing according to this, therefore can not only limit claim of the present invention with present embodiment, be all equal variation or modifications of doing according to disclosed spirit, still drop in the claim of the present invention.
