Embodiment Construction

[0012] Microcomputer life-saving alarm digital positioning system, such as figure 1 shown. PC is a system data processing computer with A / D data acquisition board inserted, and HL is a 20 mA precision constant current source for driving the bus. The output terminal of the constant current source is connected with the positive pole of the bus and the data input terminal of the A / D data acquisition board, and the ground wire is connected with the negative pole of the bus and the negative pole of the A / D board input. K1-KN are N alarm switches connected in parallel at different positions of the bus, and their serial numbers are marked on the corresponding positions of the monitored target plan. The end of the bus is connected to the terminal box ZDH. Inside the box is a resistor with a low temperature coefficient. The terminal box can provide the temperature compensation data of the bus resistance and the bus open circuit fault signal for the system computer. When an alarm is r...

Abstract

The invention discloses a micro-computer rescue alarm digitalized location system and belongs to the electronic technical field. The invention mainly solves the means that the rescuee cries for help to the external world and provides the rescue personnel with accurate rescue target. The invention divides the monitoring space into n small spaces, each small space is provided with an alarm switch (K1-KN), the serial numbers of the switches are marked to the corresponding positions of the plane figure of the monitored target in the computer, then the switches and the computer in the duty room are connected by two buses. The computer in the duty room can simply display which switch alarms when the rescuee presses the alarm switch beside the rescuee; when the invention is used in a coal mine, the invention can rescue the survivals in time and effectively reduce the secondary casualty quantity; when the invention is used in a large-scale building, the invention can obtain the multi-party rescue from the fire control personnel for the rescuees in a fire accident; when the invention is used in a residential district, the home property and human security of the residents can be guarded by district security guards for 24 hours.

Description

technical field [0001] The invention relates to a microcomputer life-saving alarm digital positioning system, in particular to a digital positioning part for an alarm target realized by a switch array in the system, which belongs to the field of electronic technology. Background technique [0002] In accidents such as flooding, gas explosions, and collapses in coal mines, once survivors are trapped, they can only rely on themselves to call or knock on iron pipes to call the police for help. If you are trapped for a long time, you will lose the ability to call for help and call the police due to lack of physical strength, and lose your chance of survival. [0003] In some public places, such as theaters, hospitals, shopping malls and other large buildings, people are often trapped after a fire, and are suppressed on the ground by fireworks. Often because there is no means of alarm, or the exact location cannot be told, Without timely assistance from firefighters. [0004] I...
