The embodiment of the present invention provides a kind of wireless device radiation control method, and as shown in Figure 1, the method comprising the steps of:
S101. detecting step: when destination object enters preset range, the distance of detected target object and described wireless device.
Research shows that electromagnetic radiation forms the relation decay of inverse square with the increase of field source distance, therefore, the method hypothesis of the embodiment of the present invention is in certain distance range, without controlling radiation, once, and destination object enters in the unsafe range set, also the i.e. interior radiation meeting of this scope causes adverse effect to destination object to a great extent.Take wireless router as example, and for wireless router, outside its half meter, the radiation meeting decays rapidly.Therefore, in the method for the embodiment of the present invention, when this wireless device is wireless router, this preset range is preferably distance and is no more than in the scope of this wireless router 1m.Wireless device in the method for the embodiment of the present invention can comprise the wireless transmitting-receiving equipments such as wireless router, mobile phone, portable set.And destination object can be any objects that vital sign is arranged such as people, animal.This distance can obtain by the sensing equipment perception, for example, and by microphone array, make a video recording first-class device-aware destination object corresponding distance and zone.The method of measurement of this distance also can be used other modes well known to those of ordinary skill in the art, in this not restriction of conduct to the embodiment of the present invention.
S102. set-up procedure: according to the priority of described distance, wireless device packet waiting for transmission and the transmission situation of packet, dynamically adjust radiation mode.
It should be noted that, in the method for the embodiment of the present invention, packet espespecially can be indirectly or the IP packet directly obtained from this wireless device, the bag transmitted on the internet that the IP packet is the ICP/IP protocol definition, transmission for the packet that meets different service types, the priority of the packet of having preset in the type of service field in the IP data packet header, for realizing the requirement of Qos service quality.When this wireless device is wireless router, as three-layer network appliance, wireless router is being undertaken the important task of the hinge of the network that each logic separates, at the wireless router place, can be resolved the IP packet, thereby directly obtain the priority of each packet, wireless router is processed accordingly packet with reference to this packet priority when packet is forwarded.
To sum up, the method of the embodiment of the present invention can be adjusted the radiant power of wireless device according to priority and the transmission situation thereof of wireless device packet waiting for transmission in specific scope, thereby realizes providing the purpose that reduces as much as possible radiation under the prerequisite of good QoS.
Tool is sayed it, in described set-up procedure S102, can adjust radiation mode by the transmitting power that reduces this wireless device.But should not affect as far as possible the carrying out of session (Session) corresponding to business that qos requirement is higher, usually, the priority of the associated packet of the session that the business that qos requirement is higher is corresponding is usually very high, therefore, the method of the embodiment of the present invention, under the prerequisite of not interrupting at least transmission of highest priority data bag, reduces the transmitting power of described wireless device.
According to concrete radiation control strategy, the method for the embodiment of the present invention can realize reducing the transmitting power of described wireless device under the prerequisite of not interrupting at least transmission of highest priority data bag by several modes:
In the method for the embodiment of the present invention, the transmission situation of the packet of indication comprises the packet loss of targeted wireless device.
Described set-up procedure S102 can further comprise:
S1021. reduce the transmitting power of described wireless device, until the present packet loss of described wireless device, in default packet loss scope, also makes, deserve front packet loss for the arbitrary value in this default packet loss scope.
Packet loss is that lost data packets quantity accounts for the ratio that sends packet, in order to meet basic qos requirement, and can be in advance according to its packet loss scope of the corresponding business setting of this wireless device.Reduction by transmitting power reduces in the process of radiation, directly the packet loss of targeted wireless device is increased to the arbitrary value in this default packet loss scope under the prerequisite of not interrupting at least transmission of highest priority data bag, can reduce to a certain extent the radiation of this wireless device.
Minimum in order as far as possible the radiation of wireless device to be down to, the method for the embodiment of the present invention also can be proceeded step after step S1201:
S1022. contrast current transmit power and the target transmit power of described present packet loss described wireless device in described default packet loss scope the time;
S1023. when described current transmit power is not less than described target transmit power, the transmitting power of described wireless device is continued to be reduced to described target transmit power.
Target transmit power sets in advance for the impact that may cause destination object with reference to electromagnetic radiation.For example, scientific research is found, while for Whole Body raying exposure dose, being the uncommon volt of 0-0.25, there is no significant injury, and the uncommon volt of 0.25-0.50 can cause the variation of blood, but without grievous injury, etc.Can radiation threshold value be set flexibly and then corresponding target transmit power is set for different object of protections and different protection purposes.
The method of the embodiment of the present invention is in the transmission of not interrupting highest priority data bag at least and after the packet loss of wireless device is increased to being positioned at this default packet loss scope, can also further transmitting power be reduced to target transmit power, thus the reduction radiation of maximum possible.
In addition, except above-mentioned adjustment mode, it is target that the method for the embodiment of the present invention can also meet the high emission frequency destination object not impacted, and directly the transmitting power of wireless device is adjusted to this target transmit power.Also, described set-up procedure S102 also can further comprise:
S1021. the Initial Trans of described wireless device is reduced to this target transmit power.
Minimum in order as far as possible the radiation of wireless device to be down to, the method for the embodiment of the present invention also can be proceeded step after step S1201:
Present packet loss and the default packet loss scope of described wireless device when the transmitting power that S1202. contrasts described wireless device is described target transmit power;
S1203. be less than the lower of default packet loss scope in described present packet loss and prescribe a time limit, reduce the transmitting power of described wireless device, until described present packet loss is in described default packet loss scope.
The method of the embodiment of the present invention is after the transmission of not interrupting highest priority data bag at least and being reduced to target transmit power by the transmitting power of wireless device, can also further reduce transmitting power according to the packet loss of wireless device and fall, thereby in the reduction radiation that guarantees maximum possible under the unbroken prerequisite of packet that wireless device institute must transmit.
Have again, except above-mentioned adjustment mode, the method for the embodiment of the present invention can also consider targeted wireless device the packet that must transmit and the high emission frequency destination object not impacted, the transmitting power of wireless device is adjusted.Also, described set-up procedure S102 also can further comprise:
S1201. take target transmit power as target, progressively reduce the transmitting power of described wireless device, and guarantee that the present packet loss of described wireless device is no more than default packet loss scope.

In addition, the method of the embodiment of the present invention reduces radiation by the transmitting power that reduces wireless device under the prerequisite not interrupting at least transmission of highest priority data bag, except the transmission of highest priority data bag need guarantee, the type of service that other should guarantee not interrupt transmission also can be set as required, for example, the packet that priority is time one-level; For destination address (IP+ port or URL) identical and the specific time period (for example, one minute) surpass the corresponding packet of connection request of predetermined number, show that the user is strong to the connection requirement of this destination address, the transmission of this type of packet also should guarantee normally, therefore, this type of packet is also processed according to the highest priority data bag.
In addition, wireless device (for example, wireless router) radiation value and its operating state are in close relations, (take wireless router as example when the up/down row data flow of wireless device is very large, during data download state at other equipment by the wireless router access network in high flow), the radiation value of wireless device will be relatively high, and even moment has a very high value, therefore, the method for the embodiment of the present invention also comprises step:
Control described radiation mode by the mode that the threshold value throughput is set, increase sharply to avoid radiation.
Correspondingly, the method for the embodiment of the present invention also comprises step:
Buffer memory surpasses the packet of described threshold value throughput.
Connection for session after the data packet recovery of simplifying the interruption transmission, transmission for the packet interrupted, the method of the embodiment of the present invention is also usingd this wireless device as the Connection Proxy of the corresponding session of packet of having interrupted, and is also that the session connection of announcement session both sides between them still exists.The method of the embodiment of the present invention is a dynamic process to the adjustment of wireless device transmitting power, when the distance increase between the destination object wireless device even exceeds preset range, wireless device will be adjusted the restriction to its transmitting power automatically, in this process, some packets that are interrupted transmission can constantly recover along with the increase of transmitting power.When recovering transmission, the bipartite connection of the session that the method for the embodiment of the present invention will be recovered acted on behalf of, and the packet of release buffer memory.
It should be noted that; according to different application scenarioss; for example; in the situation that this wireless device is the wireless router placed in family; destination object can be the kinsfolk of this family; especially the child in the kinsfolk, and want, by this wireless router access network the people that enjoys network service, can not do protection for other.Now, the method for the embodiment of the present invention also comprises step:
