Description

Technical Field

[0001] The present invention relates to the technical field of intelligent buildings, and in particular to a security monitoring device and a monitoring method. Background Art

[0002] The security monitoring system uses optical fiber, coaxial cable or microwave to transmit video signals in a closed loop, and constitutes an independent and complete system from camera to image display and recording. It can reflect the monitored object in real time, vividly and truthfully, not only greatly extending the observation distance of the human eye, but also expanding the function of the human eye. It can replace manual long-term monitoring in harsh environments, allowing people to see everything that actually happens at the monitored site and record it through a video recorder. At the same time, the alarm system equipment alarms against illegal intrusions, and the generated alarm signal is input into the alarm host, which triggers the monitoring system to record and record.

[0003] Chinese patent application number CN202010142357.9 discloses an intelligent building security monitoring device. Although the application solves the problem of clearing the smoke at the camera to the outside, spraying water to extinguish the fire and protecting the camera from rapid damage, the application uses a smoke alarm. In daily use, when smoking occurs indoors, such as in devices such as humidifiers, the smoke floats up and triggers the smoke alarm, which then causes an accidental triggering, causing water to spray indoors, which limits the use of the device and makes it impossible to ensure the stability of the device during use. Improvements are needed to address this problem.

[0004] Therefore, it is necessary to design a security monitoring device and monitoring method that is highly practical and can ensure the stability of the device. Summary of the invention

[0005] The object of the present invention is to provide a security monitoring device and a monitoring method to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: a security monitoring device, comprising a mounting base rotatably connected to a protective shell on the front side, a camera body being arranged at the front end of the protective shell, a spray cooling mechanism being arranged at the top of the protective shell, a linkage mechanism being arranged at the bottom of the protective shell, and a mist blowing mechanism being arranged inside the protective shell.

[0007] The spray cooling mechanism comprises:

[0008] A water flow inlet pipe is provided at the top of the water flow inlet pipe, an end of the connecting pipe three away from the water flow inlet pipe is fixedly connected to a water spray rack, a water spray assembly is fixedly connected to the bottom of the water spray rack, and an atomizing water spray port is fixedly connected to the bottom of the water spray assembly.

[0009] According to the above technical scheme, the mist blowing mechanism includes a protection box, a ventilation box, an ash filter box, a ball fan, a suction box, a connecting pipe, a connecting pipe 1, a connecting pipe 2, a converging pipe, an air jet and an air flow guide frame. The protection box is fixedly connected to the rear end of the top of the protective shell, the ventilation box is fixedly connected to the right side of the top of the protection box, the ash filter box is fixedly connected to the top of the protection box on the outside of the ventilation box, the ball fan is arranged inside the ventilation box, the suction box is fixedly connected to the right side of the top inside the protection box, the connecting pipe is fixedly connected to the bottom of the suction box, the connecting pipe 1 is fixedly connected to the middle of the bottom of the connecting pipe, the connecting pipe 2 is fixedly connected to one end of the connecting pipe away from the connecting pipe, the converging pipe is fixedly connected to the front end of the connecting pipe 2, the air jet is fixedly connected to the front of the converging pipe, the air flow guide frame is fixedly connected to the top of the front of the protective shell, and the front of the air flow guide frame is inclined with an inclination angle of 60 degrees.

[0010] According to the above technical solution, the linkage mechanism includes a temperature sensing controller, a water pipe access assembly, a solenoid valve and an electric push rod. The temperature sensing controller is fixedly connected to the middle of the bottom of the protective shell, the water pipe access assembly is fixedly connected to the bottom end of the bottom water flow access pipe, the solenoid valve is fixedly connected to the bottom end of the water pipe access assembly, and the electric push rod is fixedly connected to the inner wall of the back side of the protective shell.

[0011] According to the above technical solution, the front end of the electric push rod is fixedly connected to the camera body, the inner wall of the protective shell is fixedly connected to a guide rod on the outside of the electric push rod, and the left and right sides of the back of the camera body are slidably connected to the guide rod.

[0012] According to the above technical solution, drainage grooves are provided on both sides of the protective shell, and the solenoid valve and the electric push rod are electrically connected to the temperature sensing controller.

[0013] According to the above technical solution, a filter layer is arranged on the top of the ash filter box, and the filter layer is made of a cotton mesh, which can perform adsorption and filtration work on the inhaled air.

[0014] A security monitoring method includes the following steps:

[0015] S1. Connect the camera body to an external power source.

[0016] S2. The environment can be monitored by opening the camera body.

[0017] S3. Under normal conditions, the camera body is set outside the protective shell. When a fire occurs, the temperature sensing controller senses that the temperature has risen to the warning value. At this time, the solenoid valve opens, and the external water pipe guides the water flow into the sprinkler rack through the solenoid valve, and finally sprays the water out in an umbrella shape through the atomizing nozzle.

[0018] S4. When the temperature sensing controller senses that the temperature rises to the warning value, the electric push rod works to shrink the camera body into the protective shell. At the same time, when the ball fan works, the air is transmitted to the confluence pipe through the connecting pipe 1, and finally blown out through the air jet to blow away the trace smoke floating on the front of the camera body.

[0019] S5. When the temperature sensed by the temperature sensing controller drops to a safe value, the solenoid valve is closed, and at the same time, the electric push rod moves the camera body to the outside of the protective housing.

[0020] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0021] According to the present invention, when a fire occurs indoors, the smoke in the room floats upwards, and at the same time, the heat rises in the room. When the indoor temperature is too high, the temperature sensing controller senses the temperature rise, and then controls the solenoid valve and the electric push rod to work. At this time, the solenoid valve opens, allowing the water flow to enter the water flow access pipe, so that the water flow is sprayed out in an umbrella shape through the atomizing water spray port to form a barrier to block the smoke, so that the camera body area can still be used for video recording, effectively reducing the smoke blocking the camera. At the same time, the electric push rod controls the rear half of the camera body to move and shrink into the protective shell, leaving the camera body flush with the outer wall of the protective shell. Although the monitoring range is reduced, the safety of the camera body can be guaranteed, so that the vicinity can still be monitored when the fire is serious. When the indoor temperature is lower than the alarm value set by the temperature sensing controller, the solenoid valve is closed, and at the same time, the electric push rod is controlled to move the camera body out of the protective shell;

[0022] By setting up a mist blowing mechanism, when a fire occurs, the ball fan will suck in air from the top of the ash filter box. At the same time, by setting up a filter layer, the inhaled air can be filtered. The inhaled air is then discharged through the jet port. At the same time, the air blown out of the jet port can be guided by the airflow guide frame and blown to the front of the camera body to prevent excessive smoke from affecting the monitoring of the camera body.

At this time, the solenoid valve 503 opens, and the external water pipe guides the water flow into the water spray rack 403 through the solenoid valve 503, and finally sprays the water flow in an umbrella shape through the atomizing water spray port 405.

[0047] S4. When the temperature sensing controller 501 senses that the temperature rises to the warning value, the electric push rod 504 works to shrink the camera body 2 into the protective shell 6.
