BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Figure 1 It is a module diagram of a smart electrical fire monitoring and linkage system provided by the present utility model. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, in combination with the drawings and the specific embodiments, the present utility model will be further described. It should be noted that, on the premise of no conflict, any combination of the following-described embodiments or technical features can form a new embodiment.

[0022] As Figure 1 shown, the present utility model provides a smart electrical fire monitoring and linkage system, including an electrical fire monitoring device, an electrical fire fighting drive device, a main control device, and an intelligent circuit breaker.

[0023] Among them, the electrical fire monitoring device is installed at the monitoring point and is used to obtain electrical fire data to realize the acquisition of the monitoring data of the fire.

[0024] The electrical fire fighting drive device is connected to the fire fighting equipment and is used to drive the work of the fire fighting equipment to take corresponding fire fighting measures to control the fire situation of the fire.

[0025] Preferably, the main control device includes a protective cover and a main control board arranged in the protective cover. The main control board is provided with a microcontroller, an RS485 communication module, a local communication module, a storage module, and a first power supply module. Among them, the microcontroller is connected to the electrical fire monitoring device through the RS485 communication module and is used to obtain the electrical fire data of the electrical fire monitoring device through the RS485 communication module so as to realize the monitoring of the fire.

[0026] The microcontroller is communicatively connected to the intelligent circuit breaker through the local communication module, and is used to send a control signal to the intelligent circuit breaker to make the intelligent circuit breaker perform an opening operation when the electrical fire data meets the preset triggering condition, so as to control the disconnection of the power supply. Among them, the preset triggering condition refers to setting corresponding early warning triggering conditions inside the main control device. For example, when the electrical fire data exceeds the set electrical fire data threshold, the opening operation of the intelligent circuit breaker is triggered. That is to say, the storage module is electrically connected to the microcontroller and is used to store the preset triggering condition, the electrical fire data threshold, etc. The preset triggering condition includes an opening triggering condition and may also include a closing triggering condition. The utility model realizes the monitoring of fire data by setting an electrical fire monitoring device, so that when an abnormality such as a fire occurs, while driving the fire-fighting equipment to perform fire-fighting measures through the electronic fire-fighting driving device, the disconnection of the power supply is also realized through the opening operation of the installed intelligent circuit breaker, so as to avoid the further expansion of the fire and realize the linkage monitoring of the fire. Among them, the power supply here refers to the power supply of electrical equipment, the power supply for fire to enter the house, etc. For example, if an electrical equipment may catch fire due to abnormal operation, the power supply of the cable circuit where the electrical equipment is located can be disconnected through the intelligent circuit breaker to avoid the further expansion of the fire, etc.; similarly, when a certain room or house catches fire, the power supply for the house to enter can be disconnected through the intelligent circuit breaker to cut off the cable circuit and avoid larger fires caused by other cables catching fire due to the fire. Among them, the installation position of the intelligent circuit breaker can be installed according to actual needs. For example, it can be installed at the power supply for entering the house or the power supply for a certain individual electrical equipment, etc. The utility model does not make specific restrictions.

[0027] One end of the first power supply module is electrically connected to the commercial power, and the other end is electrically connected to the main control board, and is used to convert the commercial power into the corresponding power supply to provide the power supply for the main control board. The first power supply module in the utility model is used to provide the power supply for the microcontroller, communication module, storage module, etc. on the main control board to ensure the normal operation of the microcontroller.

[0028] Preferably, the main control device and the intelligent circuit breaker in this embodiment are wirelessly communicatively connected, and their installation positions can be different to ensure the absolute safety of the main control device and be unaffected by the fire. In this way, it can be ensured that the opening operation can be realized in time through the intelligent circuit breaker when a fire occurs, and the work of the corresponding fire-fighting equipment can be driven and controlled through the electrical fire-fighting driving equipment.

[0029] Further, a remote communication module is also provided on the main control board. The microcontroller is also communicatively connected to a remote service center through the remote communication module, and is configured to generate an anomaly notification and upload the anomaly notification to the remote service center through the remote communication module when the electrical fire data meets a preset trigger condition, and to receive a control instruction issued by the remote service center to control the intelligent circuit breaker to perform opening and closing operations according to the control quality. That is, the present utility model realizes the upload of the anomaly notification by communicating the main control device with the remote service center, so as to understand the on-site situation through the remote service center and take corresponding measures in a timely manner. At the same time, the present utility model can also remotely control the opening and closing of the intelligent circuit breaker.

[0030] Further, a video monitoring device is also included. The microcontroller is connected to the video monitoring device and is configured to start the video monitoring device to obtain on-site image data while sending a control signal to the intelligent circuit breaker to cause the intelligent circuit breaker to perform an opening operation. At the same time, the microcontroller also uploads the obtained on-site image data to the remote service center through the remote communication module, so that the remote service center can judge the on-site fire situation, etc. based on the on-site image data, so as to take corresponding measures.

[0031] More preferably, the protective cover includes a protective housing and a cover plate, and the cover plate is detachably installed at the opening of the protective housing. A display screen, function buttons and a warning device are provided on the cover plate. The display screen, function buttons and warning device are all electrically connected to the microcontroller. The display screen is used to display the electrical fire data of the electrical fire monitoring device. The data collected by the electrical fire monitoring device, such as temperature value, current value and leakage current value, etc., is displayed through the display screen, and at the same time, the time of anomaly occurrence, etc. can also be displayed.

[0032] The function buttons include a power on / off button, a reset button, a manual opening and closing control button and a network configuration button. Among them, the power on / off button is used to power on and off the main control device. The reset button is used to reset the main control device. For example, when the main control device is abnormal or needs to be reset, its reset can be achieved through the reset button. The manual opening and closing control button, that is, for example, when the device needs to be repaired, the opening and closing operations of the intelligent circuit breaker can be achieved through the manual opening and closing control button. The network configuration button is used to achieve network configuration operations between the main control device and the intelligent circuit breaker, etc.

[0033] The warning device includes a warning light and / or a horn. The warning device is electrically connected to the microcontroller of the main control device and is configured to achieve an alarm through the microcontroller, such as alarm through warning light flashing and / or alarm through horn sound, etc. That is, when the main control device sends a control signal to the intelligent circuit breaker to cause the intelligent circuit breaker to perform an opening operation, the warning device is controlled to emit an alarm signal.

[0034] More specifically, the electrical fire monitoring device includes a temperature probe, a current probe, and a leakage current probe. Among them, the temperature probe is used to obtain the temperature value of the monitoring point. The current probe is used to obtain the current value of the monitoring point. The leakage current probe is used to obtain the leakage current value of the monitoring point. Generally speaking, when the cable is abnormal or on fire, the temperature on the surface of the cable will increase sharply. Therefore, corresponding monitoring points can be set on the cable, and temperature probes, etc. can be installed. At the same time, by setting a preset temperature threshold in the system, the temperature sensor can then monitor the temperature on the surface of the cable in real time. Once it is found that the detected temperature exceeds the preset threshold, it is considered that there is a fire or other abnormality.

[0035] In addition, each monitoring point can be equipped with a temperature probe, a current probe, and / or a leakage current probe in the electrical fire monitoring device according to actual needs. That is, the types of electrical fire monitoring devices installed at one monitoring point can be one or more, and can be adjusted appropriately according to the location of the monitoring point.

[0036] Specifically, the temperature probe, the current probe, and the leakage current probe are respectively connected to the microcontroller through the RS485 wireless communication module. By using the RS485 wireless communication method to realize the communication connection between the electrical fire monitoring device and the microcontroller, problems such as interference and too long cables can be avoided.

[0037] Furthermore, the intelligent circuit breaker can be installed at the corresponding position according to the actual situation. For example, when there are multiple independent spaces in a hotel or a residence, if an intelligent circuit breaker is set in each space, a main control device can be set to realize the independent control of multiple intelligent circuit breakers. That is, by binding the intelligent circuit breaker to the monitoring point, that is, binding the electrical fire monitoring device to the corresponding intelligent circuit breaker, once the electrical fire data of the corresponding electrical fire monitoring device exceeds the preset threshold, the corresponding intelligent circuit breaker can be controlled to open by querying the intelligent circuit breaker bound to the electrical fire monitoring device, so as to realize the fire monitoring of the corresponding independent space. At the same time, this design method also saves equipment costs and does not require a main control device to be set for each intelligent circuit breaker.

[0038] That is, the main control device is also used to send a control signal to the intelligent circuit breaker bound to the electrical fire monitoring device to make the corresponding intelligent circuit breaker execute the opening operation when the electrical fire data meets the preset trigger condition. Among them, the binding relationship between the electrical fire monitoring device and the intelligent circuit breaker is also stored in the storage module of the present utility model.

[0039] Furthermore, one side of the cover is fixedly connected to one side plate of the housing through a hinge, and a lock is installed at the other end. A lock hole matching the lock is installed on the other side plate of the housing, and the lock hole is fixed to the lock hole by a key, thereby fixing the cover to the housing. When the main control device needs to be repaired, the lock can be opened by the key to open the cover, so that the main control device inside the housing can be repaired conveniently.

[0040] Preferably, the utility model further includes a second power supply module and an energy storage module. Among them, one end of the second power supply module is connected to the mains, and the other end is electrically connected to the corresponding intelligent circuit breaker and the energy storage module. That is, the utility model provides power supply to the intelligent circuit breaker through the second power supply module to ensure that after the gate opening operation, the intelligent circuit breaker is prevented from being powered off and unable to work. In addition, this embodiment also provides power supply to the intelligent circuit breaker after the mains power is cut off by setting an energy storage module to ensure the stable operation of the power supply.

[0041] Preferably, the utility model also includes a mobile terminal. The main control board is provided with a Bluetooth communication module. The mobile terminal is connected to the microcontroller of the main control device through the Bluetooth communication module to realize data interaction with the microcontroller. Specifically, the mobile terminal is used to send a control signal to the microcontroller to control the opening and closing control of the intelligent circuit breaker. By using the mobile terminal to control the intelligent circuit breaker, manual contact with the main control device is avoided, and the operation is convenient. For example, the mobile terminal can realize the control of the intelligent circuit breaker by installing the corresponding APP or developing a small program.

[0042] Similarly, when the circuit returns to normal, a control signal can be sent to the main control device through a mobile phone or server, so that the main control device controls the intelligent circuit breaker to perform a closing operation according to the control signal, so that the electrical appliance is connected to the power supply and enters a normal working state.

[0043] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
