Disclosed are various embodiments for security systems for schools and similar structures. Various security devices may be monitored in a structure, such as a school, where at least one of the security devices includes a wall-mounted duress alarm, an electronic keypad, a radio-frequency identification (RFID) reader, a card access reader, a decibel meter, a smoke detector, or a mobile computing device. In response to a signal from one of the security devices being indicative of a breach having occurred in the structure, a predetermined breach policy may be automatically implemented that may include, for example, compartmentalizing a region of the structure by performing an automated closing of a door that separates the region of the structure from another region of the structure.

The invention discloses an intelligent burglary-proof detecting device and method. The intelligent burglary-proof detecting device comprises a small-size laser radar, a burglary-proof door, an automatic door, a pressure sensor, a dot matrix camera system, a fingerprint unblocking system and a wireless alarming device, wherein the small-size laser radar and the burglary-proof door are arranged at an exit of an aisle, the pressure sensor is arranged at the floor surface of the aisle floor, the dot matrix camera system is arranged below the aisle floor, the aisle floor is a one-way transparent floor, the fingerprint unblocking system is arranged at the automatic door at the dead end of the aisle, the small-size laser radar is connected to the dot matrix camera system and the pressure sensor, and the small-size laser radar, the dot matrix camera system, the pressure sensor, the burglary-proof door, the wireless alarming device and a fingerprint unblocking device are all connected to a computer. According to the intelligent burglary-proof detecting device and method, through the adoption of a burglary-proof measure of using the dot matrix camera to scan and combine the pressure sensor and the fingerprint unblocking device, a fast alarming function is achieved and a stranger can be controlled at the same time, which makes it convenient for a user to implement the burglary-proof measure beforehand so that the property security can be guaranteed.

The invention discloses a substation anti-theft method, which includes a substation, a monitoring room, a remote monitoring module, a field module, and a mobile terminal. Monitor the module and interconnect the communication; S2: When a thief enters the substation, if he enters from the door of the substation, the sensor in the field module detects the entry and sends a signal to the remote monitoring module; S3: The remote monitoring module sends an alarm after receiving the signal , prompting the staff in the monitoring room to judge whether to activate the anti-theft lever in the substation through the display device; S4: When the staff in the monitoring room is not there, the remote monitoring module sends the information to the mobile terminal if the alarm is not processed within the preset time; S5: Work The personnel judge the situation of the substation on the mobile terminal, and send the control signal to the remote monitoring module through the mobile terminal to cancel the alarm or perform anti-theft operations.

A new burglar measure device which can be adopted by the store side, such as a convenience store, is provided. The magnet unit (1) of the burglar measure device is in such a structure including a net (N) holder (the first holder member (10) and the second holder member (20)), a permanent magnet (25) embedded in the net holder, a ceiling mounting tool (40) mounted on the ceiling, an iron core (45) fixed to the ceiling mounting tool, a coil (35) winding around the core of the iron core,and an operating switch for energizing the coil. When the coil is de-energized, the iron core is adsorbed by the permanent magnet so that the net holder is held on the ceiling mounting tool. By energizing the coil, the iron core is magnetized in the direction of repulsion to the permanent magnet, and the net holder is removed from the ceiling mounting tool.

The invention relates to an infrared body sensing emergency control circuit and a fast stop and capture device, the infrared body sensing emergency control circuit comprises a power supply, a human body detection control circuit, an alarm signal output circuit, a mechanical equipment fast stop loop and a relay, the power supply is electrically connected with the human body detection control circuit, the human body detection control circuit is connected with the alarm signal output circuit, the coil node of the relay and the output code of the alarm signal output circuit are connected in parallel, the mechanical equipment fast stop loop and the normally closed node of the relay are connected in series, the human body detection control circuit detects an abnormal human body signal and controls the output node of the alarm signal output circuit so that the coil of the delay obtain the electricity, then the normally closed node of the relay is turned on, and the normally closed node of the relay is disconnected so that the fast stop loop of the mechanical equipment is disconnected. According to the invention, the device can alarm and perform corresponding fast stop or capture movement at the first time of the accident, and the occurring of mechanical wounding accident or significant property lose can be greatly reduced.

The invention discloses an extrusion and repellent triggered high-safety anti-collision door, and relates to the technical field of building materials. The anti-collision door comprises a door frame and a door panel. The door panel comprises symmetrical side doors. One side of each side door is rotationally connected with the inner wall of the door frame. The side, away from the door frame, of each side door is rotationally connected with an anti-collision door body. A collision groove is formed in one side of the anti-collision door body. Catching grooves are symmetrically formed in the two sides of the collision groove. A universal ball is rotationally connected between the two sides of the inner walls of each catching groove. The two sides of each universal ball penetrate through the anti-collision door body and extend into the anti-collision door body. A catching rod is fixedly connected with one side of each universal ball. By means of the extrusion and repellent triggered high-safety anti-collision door, outdoor people can be prevented from continuously colliding with the door body, activity freedom of people breaking in is limited, people breaking in can be easily caught, people breaking in are prevented from escaping while safety of indoor people is protected, the structure is simple, cost is low, protection measures are taken, and outdoor passers-by can be prevented from being accidentally injured.

A life safety system for mitigating injuries and fatalities to occupants of a multi-zone structure comprising a plurality of controllers, and coupled to said controller, a plurality of digital imaging devices, a plurality of locking mechanisms, a plurality of dispersion points for the dispersion of at least one dispersible substance, and a plurality of thermostatic members. The life safety system further comprises at least one monitoring location physically removed from at least one of said controllers and from at least one of said dispersion points and from at least one of said locking mechanisms and from at least one of said thermostatic members.
