Description

Technical Field

[0001] The present invention relates to the field of fire extinguishing technology, and in particular to a radio arc recognition 5G starting system with a temperature-sensitive fire extinguishing rope. Background Art

[0002] At present, the fire prevention and fire fighting measures for the substation cabinets, cable trenches, meter boxes, and small enclosed spaces that are prone to fire are not perfect. It is necessary to regularly inspect the equipment to promptly discover fire hazards and prevent or extinguish fires in advance. There are three prominent problems in the current fire inspection and fire fighting measures:

[0003] Problem 1: Due to interference from sunlight and background light, existing fire detection technologies often cannot effectively distinguish between the light generated by arc discharge and natural light, resulting in the failure to promptly detect fire hazards caused by arc discharge.

[0004] Question 2: To realize remote fire monitoring and alarm for multiple monitoring points, it is necessary to establish a dedicated data transmission network, which requires a large amount of work, a long construction period, and high costs;

[0005] Question 3: How to quickly confirm and activate the fire extinguishing device after discovering a fire has always been a difficult problem that plagues fire extinguishing decisions. How to reduce fire extinguishing actions in false alarms while not missing fire extinguishing measures in real fires places high demands on reliable fire extinguishing decisions.

[0006] In order to ensure safety and prevent fires, it has become a technical problem that urgently needs to be solved in this field to monitor the fire conditions in the above-mentioned areas in real time, detect the fire conditions in time and take correct fire-fighting measures quickly when there is no one on duty. Summary of the invention

[0007] The object of the present invention is to provide a radio arc identification 5G starting system with a temperature-sensitive fire extinguishing rope to solve the problems raised in the above-mentioned background technology.

[0008] To solve the above technical problems, the present invention provides the following technical solutions: A radio arc light recognition 5G startup system with a temperature-sensitive fire extinguishing rope, comprising an ultraviolet arc recognition module, a battery and power management module, a signal transmission module, a 5G stand-alone network, and a fire extinguishing rope trigger module. The ultraviolet arc recognition module and the signal transmission module are cross-linked with the 5G stand-alone network to transmit the arc alarm signal to the operation and maintenance control center and receive the disposal instructions from the operation and maintenance control center. The ultraviolet arc recognition module, the battery and power management module, the signal transmission module, and the fire extinguishing rope trigger module are cross-linked to generate a fire extinguishing signal according to the fire extinguishing criterion and the disposal instructions of the operation and maintenance control center, and start the fire extinguishing rope to extinguish the fire. The ultraviolet arc recognition module, the battery and power management module, and the battery module are cross-linked to generate the normal standby power supply and wake-up power supply of the system. The 5G stand-alone network is a specially customized independent 5G network or requires the communication provider to provide a 5G stand-alone network to ensure the real-time transmission of the arc signal.

[0009] According to the above technical solution, the ultraviolet arc recognition module includes an ultraviolet photosensitive signal acquisition unit, an ultraviolet photosensitive signal processing unit, an arc signal recognition unit, and a main control unit.

[0010] According to the above technical solution, the signal transmission module includes a data interface unit and a 5G communication control unit. The data interface unit is used to transmit data, and the 5G communication control unit receives 5G signals for feedback to execute control instructions.

[0011] According to the above technical solution, the battery and power management module includes a battery standby wake-up control circuit, a power supply drive circuit, and a battery module. The battery module is used to provide electrical energy. The battery standby wake-up control circuit is used to wake up the battery module to work. The power supply drive circuit is used to control the circuit to work.

[0012] According to the above technical solution, the fire extinguishing rope trigger module includes an interface control unit and a signal generation and drive module. The signal generation and drive module is used to drive the fire extinguishing rope to work for fire extinguishing. The interface control unit is used to transmit and identify signals.

[0013] According to the above technical solution, when multiple signal generation and drive modules apply to drive the fire extinguishing rope to start extinguishing the fire at the same time, the system will judge the fire extinguishing method of the signal generation and drive module that applies to start extinguishing the fire through the fire extinguishing method judgment module. The judgment of the fire extinguishing method is determined according to the fire extinguishing rope strength and fire extinguishing range data provided by the signal generation and drive module. The system will drive the signal generation and drive module that applies to start extinguishing the fire in the order of the fire extinguishing method.

[0014] According to the above technical solution, the judgment rule of the fire extinguishing method order is as follows:

[0015] When the system receives the fire extinguishing application from the signal generation and driving module, it records the intensity and fire extinguishing range of the signal generation and driving module. The higher the spraying intensity of the fire extinguishing medium of the fire extinguishing rope and the faster the fire extinguishing speed, the shorter the fire extinguishing time. Therefore, the system will give priority to processing the fire extinguishing rope with a higher spraying intensity; the larger the detected high-temperature range, the larger the fire range, and the system will give priority to extinguishing the fire in the area with a larger fire range.

[0016] According to the above technical solution, therefore, the order of the fire extinguishing behavior of the signal generation and driving module controlling the fire extinguishing rope is calculated from the intensity and fire extinguishing range data of the signal generation and driving module. Specifically:

[0017] W = αA + λβB

[0018] Where W is the calculated priority index of the fire extinguishing method. The larger W is, the easier it is for the fire extinguishing rope to work. α is the weight of the temperature in the fire extinguishing method index, β is the weight of the fire extinguishing range in the fire extinguishing method index, A is the spraying intensity of the fire extinguishing rope, B is the fire extinguishing range data provided by the signal generation and driving module, and λ is the adjustment coefficient.

[0019] According to the above technical solution, the specific rules for the weight of the fire extinguishing method index are as follows:

[0020] a: When the temperature at the fire scene is detected to be higher and the fire burns more vigorously, the fire extinguishing rope with a high fire extinguishing intensity is easier to extinguish the fire faster. At this time, the weight of the fire extinguishing range in the calculation of the fire extinguishing method order is reduced, and the weight of the fire extinguishing intensity in the calculation of the fire extinguishing method order is increased;

[0021] b: In the case of a wide fire range, the flame does not burn vigorously, but the flame range is large. In order to save the consumption caused by a high fire extinguishing intensity, the weight of the fire extinguishing intensity in the calculation of the fire extinguishing method order is reduced, and the weight of the fire extinguishing range in the calculation of the fire extinguishing method order is increased;

[0022]

[0023] That is

[0024] Where n is the real-time temperature, n0 is the average temperature at the fire scene, m is the real-time high-temperature range, m0 is the normal fire range, and μ is the adjustment coefficient.

[0025] Compared with the prior art, the beneficial effects achieved by the present invention are: In the present invention,

[0026] First: The present invention adopts an ultraviolet light-sensitive signal acquisition unit, an ultraviolet light-sensitive signal processing unit, an arc signal recognition unit, and a main control unit with an ultraviolet light detection function, which can effectively overcome the interference of sunlight, background light, etc., and reliably detect the fire hazards caused by arc discharge;

[0027] Second: The present invention uses high-speed real-time 5G stand-alone networking to achieve remote fire monitoring and alarm for multiple monitoring points, overcoming the problems of large engineering quantity, long construction period, and high cost existing in the establishment of a dedicated fire detection network;

[0028] Third: After a fire is detected, the present utility model can integrate the ultraviolet photoelectric arc detection results and the fire extinguishing command sent by the operation and maintenance control room through 5G, and automatically start the fire extinguishing device reliably and in real time to achieve high-efficiency real-time fire extinguishing.

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] Please refer to Figures 1-5, the present invention provides a technical solution: a radio arc light recognition 5G startup system with a temperature-sensitive fire extinguishing rope, including a purple light arc recognition module (1), a battery and power management module (3), a signal transmission module (2), a 5G stand-alone network (5), and a 120°C fire extinguishing rope trigger module (4). Among them, the purple light arc recognition module (1) relies on the high anti-interference ability of purple light to achieve reliable detection, processing and recognition of arc signals; the recognized arc signals are cross-linked with the 5G stand-alone network through the signal transmission module, and the alarm signals are sent to the operation and maintenance control room, and at the same time, the disposal instructions from the operation and maintenance control room are received; the purple light arc recognition module automatically judges and fuses the disposal instructions from the operation and maintenance control room according to the recognition results, and then generates a 120°C fire extinguishing signal to start the fire extinguishing rope for fire extinguishing. In the overall system, the purple light arc recognition module (1), the battery standby wake-up control circuit (301) and the power supply drive circuit (302) are always powered on, and the remaining modules of the system such as the signal transmission module (2), the 5G stand-alone network (5), the 120°C fire extinguishing rope trigger module (4), etc. are in the sleep state to save power consumption. When the purple light arc recognition module (1) detects an arc danger signal, it timely sends a wake-up pulse to the standby wake-up control circuit (301) to start the battery and power management module (3) to work, and starts to provide the working power supply for the entire system and the power supply required for fire extinguishing;

[0037] The purple light arc recognition module (1) includes an ultraviolet photosensitive signal acquisition unit (101), an ultraviolet photosensitive signal processing unit (102), an arc signal recognition unit (103) and a main control unit (104). Among them, the ultraviolet photosensitive signal acquisition unit (101) is the key component for arc detection. Using an ultraviolet sensor can effectively avoid the interference of sunlight, white light lamps, etc. on the arc light, and achieve high-reliability arc detection with anti-interference; the ultraviolet photosensitive signal processing unit (102) and the arc signal recognition unit (103) are software modules supporting the main control unit (104). They adopt advanced signal processing and pattern recognition technologies to filter and denoise the collected arc signals, enhance the signals, and achieve reliable recognition of the arc signals, judge the level of the fire caused by the arc, and determine whether to start the alarm and the fire extinguishing action. The main control unit (104) is the core of this module, which is composed of a low-power CPU. It controls each unit circuit and algorithm module to achieve the detection, processing and recognition judgment of the arc, and starts the battery and power management module (3) to wake up the battery power supply according to the danger level, and realizes 5G communication signal transmission and remote fire extinguishing;

[0038] The signal transmission module (2) includes a data interface unit (201) and a 5G communication control unit (202). The data interface unit (201) is composed of a single-chip microcomputer with a high-speed data interface, which can perform ranking combination, decomposition, and decoding on the transmitted data and received data to form a data source sent to the 5G communication control unit (202) and a data sink of the data received from 5G. The 5G communication control unit (202) uses the latest IoT high-speed 5G module, which can achieve seamless connection to the external 5G network. This system realizes the high-speed, low-latency, and real-time sending and receiving of fire data through an external 5G independent networking network;

[0039] The battery and power management module (3) includes a battery standby wake-up control circuit (301), a power supply drive circuit (302), and a battery module (303). The power supply drive circuit (302) has two-way drive outputs. The first path is always powered on and supplies power to the ultraviolet arc recognition module (1), the battery standby wake-up control circuit (301), and itself respectively. The second path is a controllable wake-up power supply output, which supplies power to the signal transmission module (2), the 5G independent networking (5), and the 120°C fire extinguishing rope trigger module (4) respectively to realize the working ability of the system when alarm and fire extinguishing are required. The battery standby wake-up control circuit (301) can control the output of the power supply drive circuit (302) for the first path and the second path. When the ultraviolet arc recognition module (1) detects an arc danger signal, it sends a pulse to the battery standby wake-up control circuit (301) in time, thereby starting the second path of the power supply drive circuit (302) to work and completing the system function;

[0040] The 120°C fire extinguishing rope trigger module (4) includes an interface control unit (401) and a 120°C signal generation and drive module (402). The interface control unit receives the 120°C start command sent by the main control unit (104) and sends it to the 120°C signal generation and drive module (402) to generate relevant signal waveforms that meet the requirements for the fire extinguishing rope to start working;

[0041] The judgment rules for the order of fire extinguishing methods are as follows:

[0042] When the system receives the start fire extinguishing application from the signal generation and drive module, it records the intensity and fire extinguishing range of the signal generation and drive module. The higher the spraying intensity of the fire extinguishing medium of the fire extinguishing rope and the faster the fire extinguishing speed, the shorter the fire extinguishing time. Therefore, the system will give priority to processing the fire extinguishing rope with a higher spraying intensity. The larger the detected high-temperature range, the larger the fire range. The system will give priority to extinguishing the area with a larger fire range;

[0043] Therefore, the order of the fire extinguishing behavior of the fire extinguishing rope controlled by the signal generation and drive module is calculated from the intensity and fire extinguishing range data of the signal generation and drive module. Specifically:

[0044] W = αA + λβB

[0045] Where W is the calculated priority index of the fire extinguishing method. The larger W is, the easier it is for the fire extinguishing rope to work. α is the weight of temperature in the fire extinguishing method index, β is the weight of the fire extinguishing range in the fire extinguishing method index, A is the spraying intensity of the fire extinguishing rope, B is the fire extinguishing range data provided by the signal generation and driving module, and λ is the adjustment coefficient;

[0046] The specific rules for the weight of the fire extinguishing method index are as follows:

[0047] a: When the temperature at the fire scene is detected to be higher and the fire burns more vigorously, the fire extinguishing rope with a higher extinguishing intensity is more likely to extinguish the fire faster. At this time, the weight of the fire extinguishing range in the calculation of the fire extinguishing method sequence is reduced, and the weight of the extinguishing intensity in the calculation of the fire extinguishing method sequence is increased;

[0048] b: In the case of a wide fire range, the flame burns weakly but the flame range is large. In order to save the consumption caused by a high extinguishing intensity, at this time, the weight of the extinguishing intensity in the calculation of the fire extinguishing method sequence is reduced, and the weight of the fire extinguishing range in the calculation of the fire extinguishing method sequence is increased;

[0049]

[0050] That is

[0051] Where n is the real-time temperature, n0 is the average temperature at the fire scene, m is the real-time high-temperature range, m0 is the normal fire range, and μ is the adjustment coefficient.

[0052] This fire extinguishing method can determine the priority of the fire extinguishing method according to the temperature and range of the fire scene, and then flexibly determine the targeted fire extinguishing method, avoiding the previous single fire extinguishing method, and being able to minimize the waste of fire extinguishing agent on the premise of extinguishing the big fire.
