Abstract
The invention provides an alarm system improving safety, and the system comprises a processor, a radio frequency module, a server, and a cube-shaped concrete prefabricated plate. The processor is connected with the radio frequency module, and the interior of the concrete prefabricated plate is provided with a plurality of metal wires passing through two ends of the concrete prefabricated plate. The metal wires are sequentially connected to form a metal wire strip. One end of the metal wire strip is connected with a negative electrode of a power supply, and the other end of the metal wire strip is connected with one end of a resistor and a detection pin of the processor. The other end of the resistor is connected with a positive electrode of the power supply, and the processor is used for transmitting an alarm signal to a server when the level of the detection pin connected with the metal wire strip is detected to be high. When the concrete prefabricated plate is cracked, the metal wires will be broken, and the level of the detection pin will become high. The system can achieve real-time alarm through monitoring the server, and avoids a safety problem.
