Description
（One）, technical field：
The present invention relates to a kind of intercom positioning method and can positioning interphone, more particularly to one kind realized by sniff mode
Intercom positioning method and can positioning interphone.
（Two）, background technology：
In intercom field, existing device type can be divided into two kinds from orientation angle：A kind of is common analog or digital
Intercom, only with the function of paging intercommunication, without positioning function, is merely able to realize the call between intercom carrying personnel；
Another kind is the intercom with GPS location function, and the paging function and GPS that the intercom of the type has common intercom concurrently are determined
Bit function, can realize the real-time positioning of the call and intercom between intercom carrying personnel, but in environment indoors,
GPS location has significant limitation, it is impossible to enough to realize being accurately positioned., it is necessary to grasp right in time in actual management work
Say the positional information of machine manning, can be carried out when being supervised in real time to its work, and having emergency situations and
When rescue, if can not realize being accurately positioned in intercom environment indoors, it will to management work bring it is many not
Just.
（Three）, the content of the invention：
The technical problem to be solved in the present invention is：Offer is a kind of to be realized the method for intercom positioning and can position by sniff mode
Intercom, the method for intercom positioning and can positioning interphone can be accurately positioned with outdoor indoors, and cost performance is high.
Technical scheme：
It is a kind of that the method that intercom is positioned is realized by sniff mode, sniffer and Wireless Data Transmission are installed on intercom
The power supply of device, sniffer and wireless data transmitter is provided by intercom or battery, and communication port and the wireless data of sniffer are passed
The communication port connection of defeated device, alignment system is set on the periphery of intercom, and the framing signal that intercom is located at alignment system is covered
In the range of, during positioning,
The outside broadcasting packet of alignment system timing；
Message that sniffer sniff is broadcasted to alignment system is simultaneously processed, and obtains MAC Address and RSSI value in message（Receive
Signal strength indication value）And sending wireless data transmitter to, wireless data transmitter is again by MAC Address and RSSI value with wireless
Mode send, alignment system wirelessly receiving radio data transmitter send MAC Address and RSSI value,
And the acquisition of intercom position information is carried out according to MAC Address and RSSI value.
MAC（Media Access Control or Medium Access Control）Address, free translation is media interviews
Control, or be physical address, hardware address, for defining the position of the network equipment.
Contain M localizer beacon device, N number of locating base station and a location-server in alignment system, M and N is and is more than
Natural number equal to 1, by network connection between locating base station and location-server, outwards broadcast is reported for each localizer beacon device timing
Text, message that sniffer sniff to localizer beacon device is broadcasted simultaneously is processed, and obtains MAC Address and RSSI value in each message simultaneously
Send wireless data transmitter to, wireless data transmitter again wirelessly sends MAC Address and RSSI value, it is fixed
MAC Address in each message that wirelessly receiving radio data transmitter sends of position base station and RSSI value and send to
Location-server, MAC Address and RSSI value of the location-server in each message judges intercom with each localizer beacon device
The distance between, so as to get the positional information of intercom.
In order to more be accurately positioned, the number M of localizer beacon device can also be further defined to the nature more than or equal to 3
Number.
