The object of the present invention is to provide the carry-on distress system of the alert net of a kind of urban district patrol, it can utilize the wireless tranceiver of the alert net of patrol itself, and cooperate the tracking recipient hold, when victim's carry-on main frame transmission has the mayby of PIN, the police are except can confirming victim's identity, also can follow the trail of rapidly the definite position of the spot that is injured, in time to rescue the victim.
The object of the present invention is to provide the carry-on distress system of the alert net of a kind of urban district patrol, its main frame and tracking recipient have multi-functional, via design of the present invention, can become safe, convenient, economic, quick, effective self-defence sharp weapon, cooperate by police strength simultaneously, keep watch and help defend each other to reach, diminish and wriggle the ruffian in any possible chance of committing a crime.
The objective of the invention is to be realized by following technical scheme.
The carry-on distress system of the alert net of urban district patrol of the present invention, it limits identical with radio reception frequency in the barrier is warned in patrol, and cooperate main frame and follow the trail of receiver, consist of a wireless rescuing networking, its improvements are, the radio intercommunication unit frequency that this patrol police net uses, identical with the main frame tranmitting frequency, and be limited in the hundreds of meters of short-range circumference effective; This main frame can be carried, and starts shooting when meeting situation, has sound calling for help, radio transmission, numbering transmission, delivering position signal to the function of following the trail of receiver and silence switch; This tracking receiver is held usefulness by the alert netizen person of patrol, and cooperates wireless tranceiver, meet to begin start when emergency is followed the trail of, its have the direction detecting function with apart from detecting function; Via the combination of system of the present invention, consist of again carry-on distress system easily of one simple, safety, economy.
Concrete structure of the present invention is described in detail as follows:
System of the present invention is cooperated by the alert net of main frame, tracking receiver and patrol and forms, applied know-why, it is the mutual wireless communication function that has by existing product, but consider the problems of frequency interferences, limit it and be effective range for short distance and in the hundreds of meters of circumference, it receives the wireless tranceiver that object only limits to alert net of the interior patrol in zone or police office, and therefore, its carry-on main frame transmission frequency need be same as the alert frequency of using.
The main frame of system of the present invention, carried by the user, be in off-mode at ordinary times, when taking place, ruffian or dangerous situation begin start when meeting, or send surprising sound and draw back the ruffian with fear, perhaps with mute function, send an SOS to wireless tranceiver silently and follow the trail of receiver, with in time by the advantage police strength ruffian that surrounds and seize.
The tracking receiver of system of the present invention, usually be configured on one's body the alert personnel that net of patrol, when its wireless tranceiver reception has the distress signal of distinguishing sign indicating number from the main frame user, can open this tracking receiver, and by itself have the direction detecting function with apart from the facility of detecting function, from the rescue scene that can correctly arrive at rapidly, in time finish and rescue people and the action of surrounding and seize the ruffian.
