Example one
Before describing the security method of the embodiment of the present invention in detail, a security system of the embodiment of the present invention is described with reference to fig. 1. FIG. 1 shows a framework diagram of a security system according to an embodiment of the present invention. As shown in fig. 1, the security system of the embodiment of the present invention includes a client, a server, a router, a gateway, and a device to be defended.
The client is respectively connected with the server and the router in a communication mode. The server is in communication connection with the gateway through the router. The gateway is connected with the equipment to be defended through Bluetooth communication. Install application APP on the client, the user can receive the alarm information that the server fed back through this APP, and the user can also utilize this APP to send the instruction of deploying troops to the gateway. The embodiment does not limit the communication connection mode between each two of the client, the server and the gateway, and the communication can be performed through wireless connection (for example, WIFI connection) or wired connection. In addition, the equipment to be armed is at least one of: bluetooth lock, be provided with bluetooth label's door and be provided with bluetooth label's window, in order to outwards feedback received power, these are waited to defend equipment and still have wireless or wired communication function.
Fig. 2 shows a flow diagram of a security method according to an embodiment of the present invention. As shown in fig. 2, the security method according to the embodiment of the present invention mainly includes steps S101 to S104.
In step S101, bluetooth communication between the gateway and the device to be armed is established.
Specifically, under the condition that the gateway is determined to be in the arming mode currently, Bluetooth communication between the gateway and the device to be armed is established.
Here, the APP of the client first determines whether the room is unmanned or not based on the collected detection information of the environment (for example, the room) where the device to be armed is located, and when it is determined that the room is unmanned, the client sends an arming instruction to the gateway, and the gateway switches the current mode to the arming mode in response to the received arming instruction.
In a preferred embodiment, detection devices such as an infrared pyroelectric sensor, a human body sensor or an intelligent camera are arranged in a room, and whether people are moving in the room is determined through information collected by the detection devices. Those skilled in the art can use these detection devices to collect indoor information and determine whether people are present in the room based on the collected information, and the detailed method is not described herein again. The client APP may signal the gateway when a person is away from home to set the gateway in the armed mode.
And the gateway in the arming mode establishes Bluetooth communication with the equipment to be armed. For example, the gateway transmits a bluetooth transmission signal to the device to be armed and records the transmission power of the transmitted bluetooth transmission signal, the device to be armed receives a bluetooth reception signal corresponding to the bluetooth transmission signal (because of power loss in the signal transmission process, the bluetooth signal transmitted by the gateway is referred to as a bluetooth transmission signal, and the signal received by the device to be armed is referred to as a bluetooth reception signal), the device to be armed determines and records the reception power of the received bluetooth reception signal, and the device to be armed feeds back the reception power to the gateway by using a wireless connection (for example, a WIFI connection mode) or a wired connection between the device to be armed and the gateway.
In step S102, the transmission power of the bluetooth transmission signal and the reception power of the bluetooth reception signal in the bluetooth communication are collected.
In step S103, a measurement distance between the gateway and the device to be armed is determined according to the transmission power and the reception power.
Specifically, the bluetooth ranging principle is: two bluetooth equipment communicate, and the communication carries sender's transmitting power, and the received power acceptor can know, subtracts received power through transmitting power and obtains the way loss, knows the distance through the way loss.
In this embodiment, the gateway determines a power loss (i.e., a path loss) by subtracting the received power fed back by the device to be armed from the transmission power, then obtains a distance corresponding to the determined power loss according to a preset mapping relationship between the power loss and the distance, and uses the distance as a measurement distance between the gateway and the device to be armed.
In step S104, the location status of the device to be armed is determined based on the standard distance between the gateway and the device to be armed and the measured distance.
Specifically, referring to fig. 3, an error between the measured distance and the standard distance is first calculated (step S1041). Then, it is determined whether the error satisfies a preset error range (step S1042), where the preset error range (also referred to as a fluctuation error range) can be calculated through a large number of experiments, and a change in distance beyond the error range is determined as a displacement of the device.
In a case where it is determined that the error does not satisfy the preset error range, that is, the error is outside the preset error range, it is determined that the device to be armed has a displacement (step S1043). In the case where the arming device is a bluetooth door lock, the bluetooth door lock is considered to be in an open state at this time (step S1044). On the contrary, in the case that the error is judged to meet the preset error range, namely the error is within the preset error range, it is determined that the device to be armed does not generate displacement. And under the condition that the device to be armed is the Bluetooth door lock, the Bluetooth door lock is considered to be in a closed state at the moment.
In a preferred embodiment of the present invention, the gateway generates the alarm information when it is determined that the arming device has displaced. Then, the gateway feeds the alarm information back to the client through the server, and the client presents the alarm information to the user. Or the gateway sends the alarm information to the alarm equipment for alarming through the server. Here, the alarm device may be the device to be armed, which may transmit a signal to the gateway; the alarm device can also be other devices, and alarms by acquiring the message of the device to be defended. The alarm device performs sound and light alarm or automatic call through cloud service, and the specific alarm mode is not limited in the embodiments of the present invention.
In a preferred embodiment of the present invention, the gateway further generates status record data based on the location status of the device to be armed within a preset time period, and then uploads the generated status record data to the server, so that the server stores and integrates and counts the status record data.
By applying the security method provided by the embodiment of the invention, the intelligent gateway with the Bluetooth communication function is adopted, and the Bluetooth ranging function of the intelligent gateway is utilized to monitor the motion state of the equipment to be protected in real time. Compared with the technical scheme that a detection device needs to be additionally arranged to establish a security system in the prior art, the embodiment of the invention can establish the security system by utilizing the Bluetooth ranging function of the intelligent gateway without additionally increasing the detection device, thereby reducing the scale and the cost of the security system.
Example two
The embodiment of the invention provides a security method.
The security system of the embodiment is: with reference to fig. 1, an intelligent hardware with WiFi + bluetooth communication technology is used in conjunction with a bluetooth intelligent door lock or a bluetooth tag, etc., which are popular in the market. And attaching a Bluetooth label to equipment which does not have a Bluetooth function and needs to participate in security protection, such as a glass window. The router can be connected when intelligent gateway normally works, and the bluetooth sub-equipment can realize remote control and linkage with server and APP remote communication through the gateway.
Triggering of the defense mode: APP can set a signal for a gateway to be in a defense mode when leaving home, or can be linked with detection equipment such as a sensor (whether a sensor detecting whether a person is moving has an infrared pyroelectric sensor, a human body sensor or an intelligent camera and the like) in home to detect that no person is in home, and a signal is sent to the gateway to automatically enter the defense mode.
Before the defense deploying mode is normally used, the distance between a door of a door lock and a gateway and the distance between other devices needing defense deployment are determined, and the gateway records the distance after the distance is ensured to be in the distance needing defense deployment normally; the distance can be defaulted when the device enters a defense deploying mode, the fluctuation error can be calculated through a large amount of experiments, the distance change beyond the error range is confirmed to generate displacement for the device, and at the moment, the triggering warning signal is reported to the server through the gateway and is forwarded to the user and is linked with other warning devices to give an alarm.
The security mechanism can be flexibly set and can be used for prompting that a user door is not closed well, a window is not closed well and the like.
