Problems solved by technology

[0005] After the traditional door magnetic alarm is turned on, it will generate an alarm every time the door is opened, which will cause the monitoring personnel to be frequently disturbed and cause mental stress. If it is temporarily closed, there will be a risk of omission of personnel entering and exiting

Embodiment Construction

[0018] The present invention will be described in further detail below in conjunction with accompanying drawing and specific embodiment: see Figure 1 to Figure 7 , a multi-expansion door sensor based on the network, including a door sensor host 2 installed on the door 1, a magnet 21 is installed on the door frame 11, and a radio frequency transmitter (not shown in the figure) is installed in the door sensor host 2 , when the door 1 is opened, the door sensor host 2 is dislocated away from the magnet 21, the door sensor host 2 senses the weakening of the magnetic field, and then instructs the radio frequency transmitter to send a radio frequency signal to the network host (not shown in the figure), and the network host (figure (not shown above) sends an alarm signal to the mobile terminal to alarm the owner 5 seconds after receiving the radio frequency signal.

[0019] The door magnetic host is provided with a "Huarongdao" trigger 22, the "Huarongdao" trigger 22 is composed of...

Abstract

The invention discloses a network-based multi-expansion door magnet. The network-based multi-expansion door magnet comprises a host and a magnet body; a radio frequency emitter is arranged in the host and used for sending a radio frequency alarming signal to a network host when a door is opened; the network host is used for sending the alarming signal to a mobile terminal after 5 seconds; a RoomEscape trigger is arranged on the door magnet host; a button on the RoomEscape trigger can be accurately pressed within the specified time to cancel the alarm. The network-based multi-expansion door magnet brings a scheme for freely moving the button position.

Description

technical field [0001] The invention relates to a security monitoring device, in particular to a network-based multi-expansion door sensor. Background technique [0002] Houses, factories, warehouses and other places are very sensitive to the entry of personnel. For example, places where important items are stored are generally protected by anti-theft doors and anti-theft windows, but skilled thieves can often try their best to enter, so a monitor that can monitor The equipment for people to enter and exit, the door magnetic alarm was born. [0003] The door magnetic alarm is mainly composed of a magnet installed on the door frame and a door magnetic host installed on the door. Its working principle is roughly: once the door is opened, the door and the door frame will be displaced, and the door magnetic host and the magnet will also be displaced at the same time. , at the same time, the door magnetic host senses the weakening of the magnetic field, and immediately sends a r...
