Description

Technical Field

[0001] The present invention relates to the field of kitchen control technology, and in particular to a middle-stage control system for a smart kitchen. Background Art

[0002] The core value of the kitchen central control system lies in integration, intelligence and security, and its application scenarios have expanded from industrial-grade central kitchens to home users.

[0003] Kitchen safety is the top priority in kitchen control systems. Currently, kitchen safety is mainly controlled by gas leak alarm devices. Due to the limitations of the environment and installation location, the alarm is often triggered only when the gas leakage reaches a certain triggering amount. In addition, the single alarm structure has safety hazards and is prone to alarm failure due to service life and product quality, resulting in a safety funnel. Based on this, a middle-end control system for smart kitchens is proposed. It integrates the latest Internet of Things technology into various safety measures in the kitchen, and makes a new scenario-based definition of kitchen equipment, realizing the intelligence and platformization of kitchen gas equipment, and creating a safe, comfortable and convenient new smart kitchen. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems existing in the prior art and to propose a middle-stage control system for a smart kitchen.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A mid-stage control system for a smart kitchen, including a control system based on a safety self-closing valve, a window pusher, a safety smart light, a range hood, a smart central control screen, a safety auxiliary Bluetooth NB membrane meter, and a dynamic monitoring device. The control system includes:

[0010] Crisis management and control module: This module is the control center, which is controlled by user operations. It can indirectly and directly control the operation of each module and has automatic alarm, buzzer alarm and message push functions.

[0011] As a preferred solution, the ventilation control module is based on a window pusher and a range hood. The window pusher is installed on the kitchen window and is equipped with a wind speed sensor for sensing outdoor wind speed.

[0012] The range hood is connected to the window pusher by signal, and when the range hood is turned on, the window pusher is controlled to close the kitchen window;

[0013] When the wind speed sensed by the wind speed sensor is greater than a set threshold, the window pusher is controlled to close the kitchen window.

[0014] As a preferred solution, the safety detection module is based on a safety self-closing valve, a safety smart light, a safety auxiliary Bluetooth NB membrane meter and a dynamic monitoring device;

[0015] The safety auxiliary Bluetooth NB membrane meter has a built-in sensor for calculating the gas flow rate and has over-current, idle and loss of connection protection;

[0016] The safety smart lamp is equipped with a gas leak detector for detecting gas leaks and transmitting the leak signal to the crisis control module;

[0017] The dynamic monitoring device includes a human tracking camera and an infrared camera. The human tracking camera can follow the real-time movement of kitchen personnel and issue an alarm when kitchen personnel remain stationary for a long time. The infrared camera monitors the gas stove in real time.

[0018] The safety self-closing valve is equipped with a high-resolution flow sensor and a high-precision pressure sensor. The high-precision pressure sensor can detect overpressure and underpressure during gas use and automatically cut off the gas supply pipeline. The high-resolution flow sensor can capture tiny flow changes and cooperate with the infrared camera in the dynamic monitoring device linkage module to obtain the results of tiny gas leaks.

[0019] As a preferred solution, the crisis management module is based on the intelligent central control screen, which is connected to the safety self-closing valve, window pusher, safety smart light, range hood, safety auxiliary Bluetooth NB membrane meter and dynamic monitoring device via Bluetooth and local area network respectively;

[0020] The smart central control screen has a built-in processor for receiving and transmitting signals and processing data, and is interconnected with a mobile terminal APP, and can transmit abnormal data and alarm signals to the mobile terminal APP in real time.

[0021] As a preferred solution, the lighting control module is set up based on the safety smart light, the dynamic monitoring device and the smart central control screen. The smart central control screen is provided with a control switch to control the turning on of the safety smart light. The human tracking camera in the dynamic monitoring device obtains information about people entering the kitchen and transmits a signal to the smart central control screen. The smart central control screen will control the safety smart light to turn on automatically.

[0022] As a preferred solution, when the range hood is turned on, the signal of the range hood turning on is transmitted to the smart central control screen, and the smart central control screen will automatically control the window pusher to close the kitchen window to prevent natural wind from affecting the smoke extraction path of the range hood and to prevent the gas stove fire from being blown out by excessive natural wind.

[0023] As a preferred solution, the infrared camera monitors the temperature changes of the gas stove, and verifies the gas flow detection with the safety auxiliary Bluetooth NB membrane meter and the safety self-closing valve, so as to achieve monitoring and management of the initial stage of gas leakage.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1.

[0034] Example, see Figures 1 to 2 A mid-stage control system for a smart kitchen includes a control system based on a safety self-closing valve 1, a window pusher 2, a safety smart light 3, a range hood 4, a smart central control screen 7, a safety auxiliary Bluetooth NB membrane meter 5, and a dynamic monitoring device 6. The control system includes:

[0035] Ventilation control module: This module has the function of detecting outdoor wind speed and is used to control the ventilation switching of the kitchen;

[0036] Furthermore, the ventilation control module is set up based on the window pusher 2 and the range hood 4. The window pusher 2 is installed on the kitchen window and is equipped with a wind speed sensor for sensing the outdoor wind speed.

[0037] The range hood 4 is connected to the window pusher 2 by signal. When the range hood 4 is turned on, the window pusher 2 is controlled to close the kitchen window.

[0038] When the wind speed sensor senses that the wind speed is greater than the set threshold, it controls the window pusher 2 to close the kitchen window. This function can prevent the gas stove from being blown out by external wind and prevent gas leakage at the gas stove.

[0039] Safety monitoring module: This module is used to detect gas leaks, abnormal gas flow rate, personnel status and gas stove combustion status;

[0040] Furthermore, the safety detection module is provided based on the safety self-closing valve 1, the safety smart light 3, the safety auxiliary Bluetooth NB membrane meter 5 and the dynamic monitoring device 6;

[0041] Safety auxiliary Bluetooth NB membrane meter 5 has a built-in sensor for calculating gas flow, with over-current, idle and loss of connection protection;

[0042] The Safety Smart Light 3 has a built-in gas leak detector to detect gas leaks and transmit the leak signal to the crisis control module. When gas leaks, the Safety Smart Light 3 will emit an audible and visual alarm signal, close the valve, and notify the gas company and user at the same time for timely processing and maintenance.

[0043] The dynamic monitoring device 6 includes a human tracking camera and an infrared camera. The human tracking camera can follow the real-time movement of kitchen personnel and issue an alarm when the kitchen personnel remain stationary for a long time. The infrared camera monitors the gas stove in real time.

[0044] The dynamic monitoring device 6 can monitor the people in the kitchen based on the human body recognition system, and identify and alarm when the kitchen staff stays still in a fixed posture for a long time, thereby avoiding the situation where the kitchen staff faints and falls to the ground due to gas leakage and is unable to alarm.

[0045] The safety self-closing valve 1 has a built-in high-resolution flow sensor and a high-precision pressure sensor. The high-precision pressure sensor can detect overpressure and underpressure during gas use and automatically cut off the gas supply pipeline. The high-resolution flow sensor can capture tiny flow changes and cooperate with the infrared camera in the linkage module of the dynamic monitoring device 6 to obtain the results of tiny gas leaks, thereby realizing real-time detection of tiny leaks in the gas pipeline.

[0046] Lighting control module: This module controls the lighting inside the kitchen and selects the lighting status according to the kitchen status. When the indoor gas concentration is abnormal, the gas meter is automatically shut down and the system prohibits the safety smart light 3 from switching on and off to prevent gas explosion accidents.

[0047] Furthermore, the lighting control module is set up based on the safety smart light 3, the dynamic monitoring device 6 and the smart central control screen 7. The smart central control screen 7 is provided with a control switch to control the turning on of the safety smart light 3. The human tracking camera in the dynamic monitoring device 6 obtains information about people entering the kitchen and transmits a signal to the smart central control screen 7. The smart central control screen 7 will control the safety smart light 3 to turn on automatically.

[0048] Crisis management and control module: This module is the control center, which is controlled by user operations. It can indirectly and directly control the operation of each module and has automatic alarm, buzzer alarm and message push functions.

[0049] Furthermore, the crisis control module is set up based on the smart central control screen 7, which is connected to the safety self-closing valve 1, the window pusher 2, the safety smart light 3, the range hood 4, the safety auxiliary Bluetooth NB membrane meter 5 and the dynamic monitoring device 6 via Bluetooth and local area network respectively;

[0050] The smart central control screen 7 has a built-in processor for receiving and transmitting signals and processing data, and is interconnected with the mobile terminal APP, which can transmit abnormal data and alarm signals to the mobile terminal APP in real time.

[0051] Furthermore, when the range hood 4 is turned on, the signal of the range hood 4 being turned on is transmitted to the smart central control screen 7, and the smart central control screen 7 will automatically control the window pusher 2 to close the kitchen window to prevent the natural wind from affecting the smoke extraction path of the range hood 4, and to prevent the gas stove fire from being blown out due to excessive natural wind.

[0052] Furthermore, the infrared camera monitors the temperature changes of the gas stove, and verifies the gas flow detection with the safety auxiliary Bluetooth NB membrane meter 5 and the safety self-closing valve 1, so as to achieve monitoring and management of the initial stage of gas leakage. That is, when the temperature of the gas stove is lower than the temperature when it is turned on, there is still gas flowing in the gas pipeline detected by the safety auxiliary Bluetooth NB membrane meter 5 and the safety self-closing valve 1, which proves that the gas is leaking.

[0053] Furthermore, the smart central control screen 7 has APP remote operation and touch screen operation modes. The remote operation is based on LAN control. The smart central control screen 7 has voice wake-up and voice control modes.

[0054] This invention realizes full-process risk management through a multi-layered safety protection system:

[0055] Multi-dimensional monitoring: Through the fusion of multiple sensors such as the gas flow / pressure sensor in the safety self-closing valve 1, dynamic monitoring by the infrared camera, and the gas leak detector located in the safety smart lamp 3, early warning of small leaks, abnormal flow, and changes in stove temperature can be achieved.

[0056] Intelligent linkage response: When an abnormality is detected, the system automatically triggers a four-level response mechanism including sound and light alarm, valve closing and air cutting, window opening for ventilation, and APP push notification, forming a closed-loop control of "monitoring-early warning-handling-notification".

[0057] Personnel status protection: The dynamic monitoring device 6 can provide early warning of sudden situations such as fainting through human body tracking and posture recognition, making up for the traditional system's neglect of personal safety.

[0058] The ventilation module automatically opens and closes the windows according to the wind speed threshold, and the range hood 4 and the window pusher 2 are intelligently linked to avoid wind interference with exhaust efficiency and stove stability, achieving environmental adaptive adjustment;

[0059] The human tracking camera realizes intelligent lighting that turns on when people come, and the voice / touch screen / APP multi-modal operation reduces the usage threshold.

[0060] The central control platform integrates gas meters, window pushers 2, lights and other equipment to achieve cross-device scenario linkage (such as automatic window closing when the range hood 4 is started).

[0061] Through infrared camera temperature monitoring and cross-verification of gas flow data, the accuracy of leak judgment is improved and false alarms and missed alarms are avoided.

[0062] It uses NB-IoT low-power wide area network communication and is equipped with overcurrent / disconnection protection to ensure stable operation of the system under extreme conditions.

[0063] Supports real-time monitoring of equipment status via mobile APP, and synchronization of abnormal data to the gas company to achieve preventive maintenance.

[0064] The dual detection (flow + pressure) of the self-closing valve can identify chronic leaks caused by pipeline aging and reduce energy waste while ensuring safety.

[0065] The smart lighting system is linked to gas concentration monitoring to prevent electric sparks from causing explosions by disabling switch operations, achieving dual optimization of safety and energy saving.

[0066] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
