In order to provide a technical scheme that dangerous situations can be timely, effectively and safely disposed or pre-disposed, the application provides a remote security system. As shown in fig. 10, the remote security system includes a plurality of investigation terminals S, a control platform P, and a plurality of remote control devices.

The plurality of investigation terminals are distributed in a predetermined area, for example, public places with high safety requirements, such as schools, kindergartens, railway stations, and the like, so as to collect site information for respective target places, where the site information may include image information collected by the camera device and/or sound information collected by the sound collection device, and the like. The control platform P is communicated with each investigation terminal S and is used for receiving and storing the field information sent by the investigation terminal S, and judging whether field control is needed or not according to the field information and/or judging the specific position of the field to be controlled. The remote control devices are distributed and distributed in the area and are communicated with the control platform, and after receiving a control instruction for field control sent by the control platform, the remote control devices control target persons on the field.

According to another embodiment of the application, the field information may include identity information, and the investigation terminal may be an identity information acquisition device. The identity information acquisition device covers the situation of identity verification. For example, when a target person who is present in the field deposits or withdraws money at a bank ATM machine, when the target person enters or exits a place where authentication is required, when the target person is required to be authenticated by law enforcement (e.g., traffic police). Terminals or devices for various identity information acquisition or verification are within the scope of the present application.

According to the remote security system, a plurality of investigation terminals continuously acquire field information in the preset area and gather the field information to the control platform P. The control platform P automatically and intelligently screens or artificially and cooperatively screens the site information sent by the investigation terminal, and when the potential safety hazard (such as dangerous personnel, personnel carrying dangerous articles, personnel with abnormal behaviors, and the like) is found, sends a control instruction for site control to one or more of the plurality of remote control devices to control the target person on site, so that the dangerous condition can be timely, effectively and safely (pre) dealt with.

The information collected by the investigation terminal S may also include information collected by sensor devices such as an odor sensor, a pressure sensor, and a distance sensor. For example, the pressure sensor arranged on the ground or the distance sensor arranged around the predetermined area can be used for judging the position information of the target person to be restrained according to the collected information, so that the control platform P selects the corresponding remote control device according to the position information, and further, the more accurate automatic treatment effect is realized.

The image recognition can intuitively and quickly identify the potential safety hazard, so that the image recognition is used as an optimal embodiment of the investigation terminal S. The investigation terminal S of the remote security system preferably comprises an image acquisition device, such as a camera, a camera and the like. According to different preset regional environmental conditions, the investigation terminal can be fixed, such as a video monitoring device with wired or wireless communication, a mobile capturing camera and the like; or be movable, such as patrol monitoring robots, cruise monitoring drones, rotatable or track-moving monitoring cameras, and the like.

As described above, the control platform P of the remote security system can screen the field information sent from the investigation terminal through automatic intelligent screening or manual collaborative screening. In order to improve the disposal efficiency, the control platform P and the dangerous personnel information base can be synchronized, so that the control platform P can judge whether the target person on site needs to be managed and controlled or emphatically monitored according to the face information of the target person in the image information of the image acquisition device. For example, dangerous persons are found in advance through face information comparison, the detection terminal S is controlled to monitor the dangerous persons emphatically, or a remote control device is started in advance. The control platform P can also determine whether the target person located on the site needs to be controlled according to the action feature information of the target person in the image information of the image acquisition device. For example, it is determined whether the target person has an abnormal behavior or action such as offensive or weapon based on the image information.

Under different field conditions, different countermeasures may need to be taken, so that the control platform P can perform screening classification on the received field information sent by the investigation terminal S, and different control instructions are respectively adopted for different situations. Preferably, the control platform comprises a danger classification module, and the danger classification module classifies the danger degree of the field information and sends different control instructions to the corresponding remote control terminal and/or the investigation terminal. For example, when a suspected dangerous person or a dangerous behavior is found, the investigation terminal S may be called to perform targeted information acquisition on a target person; and under the condition of finding exact danger hidden danger, controlling the remote control terminal to quickly execute a control means.

Preferably, the risk classification module classifies the risk level of the field information into a potentially dangerous situation requiring continuous monitoring, a situation requiring early warning, a situation requiring immediate disposal, and the like. In some of the above cases, the remote security system preferably performs the following operations: and under the condition that the danger degree is classified into potential dangers needing continuous monitoring, the control platform sends a control instruction for tracking the target person to the investigation terminal, and the investigation terminal tracks the target person independently or in cooperation with a plurality of the investigation terminals. And under the condition that the danger degree is graded as needing early warning, the control platform sends a control instruction of an early warning signal to the remote control terminal. The early warning signal can comprise a light early warning signal and/or a sound early warning signal, and is used for warning a target person and/or informing other people except the target person to avoid danger in the site. And under the condition that the danger degree is graded as needing immediate disposal, the control platform sends out a management and control signal of immediate disposal to the remote management and control terminal.

According to the remote security system, in order to prevent danger from occurring at the first time, the remote control terminal is usually used as a remote restraint device to restrain and dispose a target person causing danger factors. The remote control terminal preferably comprises a remotely controllable lock device, including but not limited to an entrance lock for entering the predetermined space, and the lock device maintains a locked state after receiving the immediately handled control signal, so as to limit the target person in the predetermined space. The remote control terminal can comprise a mobile device such as a robot or an unmanned aerial vehicle, and the treatment can be more flexibly performed through an acousto-optic device or a lasso, a capture net and other emission type constraint components arranged on the mobile device, so that the treatment is not limited to a certain fixed position.
