The technology that terminal wirelessly interconnects, in fact he is a high frequency radio signal.Wireless
Fidelity is the brand of a wireless network communication technique, WiFi alliance held.Purpose is to improve
Intercommunity between Wi-Fi product based on IEEE 802.11 standard.Current common people can be
WiFi and IEEE 802.11 lumps together.Even Wi-Fi is equal to wireless the Internet networking.
Wireless network refers to " Wireless Fidelity " at the category of WLAN, substantially one
Plant commercial verification, be also a kind of Wireless networking technologies simultaneously, in the past by netting twine connection computer, and nothing
Line fidelity is then to be networked by radio wave；Common is exactly a wireless router, then at this
The effective range that the electric wave of individual wireless router covers can use Wireless Fidelity connected mode to carry out
Networking, if wireless router is connected to an adsl line or other online circuit, the most again by
It is referred to as focus.
Use the circuit working face monitoring and alarming system based on radio communication of the present invention, for existing electricity
Road working face monitoring and alarming system monitoring intelligentization is relatively low, monitor overstaffed technical problem, introduces
Cordless communication network realizes the quick transmission of field data, uses the mode of images steganalysis to carry out fire
Feelings and the identification of personage, use strategy of reporting to the police by different level so that operating personnel understand scene more accurately
Situation, each working face for circuit provides effective monitoring, thus ensures the normal operation of circuit company.
