Description

Technical Field

[0001] Embodiments of the present application relate to the technical field of communication devices, and in particular, to a fire detection method, a fire detection system, a controller, and a storage medium. Background Art

[0002] In the related art, there are a large number of communication devices in a communication machine room. If a short circuit occurs in the device or the heat dissipation system fails, the temperature of the device components will rise, posing a risk of spontaneous combustion. Most of the existing fire monitoring systems for communication devices detect and alarm on a machine room basis, making it difficult to specifically identify which device catches fire. Once a fire is detected, the services of all devices will be affected and interrupted. And because it is based on the machine room, it takes a certain amount of time for the smoke to spread to the smoke detector. During this period, the fire will grow. If it can be identified in the early stage of a fire inside the device, the burned circuit boards can be reduced. There are also solutions to precisely detect whether a device catches fire or even extinguish the fire by improving the cabinet of the communication device. However, the detection system of the cabinet is not connected to the communication device, so the device still cannot identify whether it catches fire itself and cannot perform system management and log tracking. Summary of the Invention

[0032] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0033] It should be noted that although functional module division is performed in the device schematic diagram and the logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order from the module division in the device or the order in the flowchart. Terms such as "first" and "second" in the description and claims and the above accompanying drawings are used to distinguish similar objects and do not necessarily need to describe a specific order or sequence.

[0034] In the embodiments of the present application, words such as "furthermore", "exemplarily", or "optionally" are used to represent examples, illustrations, or explanations, and should not be construed as being more preferred or having more advantages than other embodiments or design solutions. The use of words such as "furthermore", "exemplarily", or "optionally" is intended to present related concepts in a specific manner.

[0035] In some cases, there are a large number of communication devices in the communication machine room. If a short circuit occurs in the device or the heat dissipation system fails, the temperature of the device components will rise, posing a risk of spontaneous combustion. Most of the existing fire monitoring systems for communication devices detect and alarm on a machine room basis, making it difficult to specifically identify which device is on fire. Once a fire is detected, the services of all devices will be affected and interrupted. And because it is based on the machine room, it takes a certain amount of time for the smoke to reach the smoke alarm. During this period, the fire will grow. If it can be identified in the early stage of a fire inside the device, the burned circuit boards can be reduced. There are also solutions to precisely detect whether a device is on fire or even extinguish the fire by improving the cabinet of the communication device. However, the detection system of the cabinet is not connected to the communication device. Therefore, the device still cannot identify whether it is on fire itself and cannot perform system management and log tracking. In summary, it is necessary to embed a set of fire detection systems in the communication device, which can not only decide whether to reduce or interrupt services according to whether the device itself is on fire, but also detect the fire at an extremely early stage to avoid greater losses.

[0036] Based on the above situation, the embodiments of the present application propose a fire detection system, a fire detection method, a communication device, and a storage medium, aiming to identify whether the device itself is on fire to decide whether to reduce or interrupt services, and to be able to detect the fire at an extremely early stage to avoid greater losses.

[0037] The following further elaborates on the various embodiments of the fire detection system of the present application in conjunction with the accompanying drawings.

[0038] As Figure 1 shown, Figure 1 is a schematic structural diagram of a fire detection system provided by an embodiment of the present application.

[0039] In one embodiment, the fire detection system includes, but is not limited to, a first fire detection module 110, a second fire detection module 120, and a monitoring module 200. Among them, the first fire detection module 110 is used to be installed at the air inlet of the communication device, the second fire detection module 120 is used to be installed at the air outlet of the communication device, and the monitoring module 200 is respectively connected to the first fire detection module 110 and the second fire detection module 120.

[0040] Specifically, the first fire detection module 110 can detect the air at the air inlet of the communication device to generate first detection data, and send the first detection data to the monitoring module 200; in addition, the second fire detection module 120 can detect the air at the air outlet of the communication device to generate second detection data, and send the second detection data to the monitoring module 200; then, after receiving the first detection data and the second detection data, the monitoring module 200 will compare the first detection data and the second detection data to obtain a comparison result, and determine the fire location according to the comparison result.

[0041] Among them, regarding the above comparison result, it can refer to the concentration comparison result between the first detection data and the second detection data, or it can refer to the reception time comparison result of the monitoring module 200 receiving the first detection data and the second detection data respectively. The embodiments of the present application do not make specific limitations on the above comparison result.

[0042] It should be noted that since the embodiments of the present application can determine whether the fire location is inside or outside the communication device by comparing the first detection data at the air inlet and the second detection data at the air outlet, it can determine whether its own communication device catches fire, and then can decide whether the service continues or is interrupted, avoiding the interruption of the services of all devices in the computer room being affected; in addition, if the fire location is inside the communication device, the embodiments of the present application can also detect the fire situation at an extremely early stage, thus avoiding greater losses.

[0043] It should be noted that regarding the above first fire detection module 110 and second fire detection module 120, both need to include at least a gas-type detection sensor. In addition, on the basis of including a gas-type detection sensor, the first fire detection module 110 and the second fire detection module 120 may also include, but are not limited to, a photoelectric-type detection sensor.

[0044] It can be understood that a gas-type detection sensor is a device for detecting gas components, usually composed of a sensitive element and a conversion element. The sensitive element is responsible for directly contacting the gas and generating an output signal related to the gas component concentration; the conversion element then converts the output signal of the sensitive element into an electrical signal that is easy to process and transmit.

[0045] It can be understood that a photoelectric-type detection sensor is a device that converts an optical signal into an electrical signal, and it works based on the principle of the photoelectric effect. When light irradiates on certain substances, the electrons of the substances absorb the energy of photons and generate corresponding electrical effect phenomena, which is the photoelectric effect. According to the different photoelectric effect phenomena, the photoelectric effect is divided into three categories: external photoelectric effect, internal photoelectric effect, and photovoltaic effect.

[0046] For example, a smoke gas detection sensor and a smoke optoelectronic detection sensor can be adopted. Among them, the smoke gas detection sensor is a device for detecting fire smoke and can achieve fire prevention by monitoring the concentration of smoke. The smoke optoelectronic detection sensor can detect smoke through an infrared pair of tubes. For example, when there is no smoke, the infrared receiving tube cannot receive the infrared light emitted by the infrared transmitting tube. When soot enters the optical maze, through refraction and reflection, the receiving tube receives the infrared light, and the intelligent alarm circuit judges whether it exceeds the threshold value. If it exceeds, an alarm is issued.

[0047] In one embodiment, the fire detection system further includes, but is not limited to, a computer room fire detection module 310. Among them, the computer room fire detection module 310 is communicatively connected to the monitoring module 200, and the computer room fire detection module 310 can send data to the monitoring module 200. For example, the computer room fire detection module 310 can send the information of a fire in the computer room to the monitoring module 200.

[0048] In one embodiment, the fire detection system further includes, but is not limited to, a network management system 320. Among them, the network management system 320 is communicatively connected to the monitoring module 200, and the network management system 320 can receive the data sent by the monitoring module 200. For example, the network management system 320 can receive the information of a fire in a device or the power-off notification information sent by the monitoring module 200.

[0049] In one embodiment, the fire detection system further includes, but is not limited to, a computer room monitoring system 330. Among them, the computer room monitoring system 330 is communicatively connected to the monitoring module 200, and the computer room monitoring system 330 can receive the data sent by the monitoring module 200. For example, the computer room monitoring system 330 can receive the information of a fire in a device sent by the monitoring module 200.

[0050] It should be noted that regarding the connection method between the first fire detection module 110 and the second fire detection module 120 and the monitoring module 200, since both the first fire detection module 110 and the second fire detection module 120 require a power supply voltage, and both the first fire detection module 110 and the second fire detection module 120 need to send the detection data to the monitoring module 200. Therefore, both the first fire detection module 110 and the second fire detection module 120 need to be connected to the monitoring module 200 through a power line and a data line.

[0051] In addition, it should be noted that regarding the above-mentioned monitoring module 200, it may include, but is not limited to, the following structural forms:

[0052] The first structural form: In the embodiments of the present application, the main control board of the communication device can be used as the monitoring module 200, and data can be reported to the network management system 320 or the computer room monitoring system 330 through this main control board. For example, the device fire information can be reported to the network management system 320 or the computer room monitoring system 330 through the main control board of the communication device, and the power-off notification information can be reported to the network management system 320 through the main control board of the communication device. Since the monitoring function is merged into the original main control board of the communication device in the embodiments of the present application, the main control board of the communication device simultaneously has the functions of device control and fire monitoring, with stronger integration, and can also reduce the device volume and save costs.

[0053] The second structural form: In the embodiments of the present application, a single board other than the main control board of the communication device can be used as the monitoring module 200, and data can be reported to the network management system 320 or the computer room monitoring system 330 through this single board other than the main control board. For example, the device fire information can be reported to the network management system 320 or the computer room monitoring system 330 through this single board, and the power-off notification information can be reported to the network management system 320 through this single board. If the monitoring function is not merged into the original main control board of the communication device, the monitoring module 200 can be separately set on a single board, and data can be reported through this monitoring module 200 and then through the main control board.

[0054] The third structural form: In the embodiments of the present application, a slot for the device operation status monitoring unit can be reserved in the communication device, and data can be reported to the network management system 320 and / or the computer room monitoring system 330 through this device operation status monitoring unit. For example, the device fire information can be reported to the network management system 320 or the computer room monitoring system 330 through this device operation status monitoring unit, and the power-off notification information can be reported to the network management system 320 through this device operation status monitoring unit.

[0055] In one embodiment, the embodiments of the present application can be applied to a communication device with an air inlet and an air outlet, and a fire detection system that can be embedded in the communication device is provided. It at least includes gas fire detection modules respectively located at the air inlet and the air outlet, the main control board of the communication device, and the network management system 320. It can also include the alarm input of the computer room fire detection module 310 and the computer room monitoring system 330. As Figure 1 shown, the power supply channel and data channel of the fire detection module are interconnected with the monitoring module 200 such as the main control board, and the alarm input signal of the computer room fire detection module 310 is also connected to the communication device. After the main control board processes the multi-source fire detection signals, an alarm is sent to the computer room monitoring system 330 and the network management system 320 is notified whether the device itself stops running.

[0056] In one embodiment, fans are respectively installed at the air inlet and the air outlet of the communication device, so that the air flow inside the device can be made to flow. Among them, the fans are mainly used to create an air flow with a fixed direction of flow in the communication device, fix the air outlet and the air inlet, and prompt the smoke to approach the fire detection module faster.

[0057] It can be understood that the embodiments of the present application do not specifically limit the number of the air inlet and the air outlet, but at least include one air inlet and one air outlet. In addition, the embodiments of the present application do not specifically limit the number of fans at the air inlet and the air outlet and the placement method.

[0058] It should be noted that the sensors of the fire detection module are all based on the principle of detecting gases related to combustion. They can be sensors for detecting the smoke concentration after a fire, or sensors for detecting the concentration of single or multiple gas products after combustion. In addition, there can be a socket on the fire detection module for easy connection to the communication device.

[0059] Among them, the gas type fire detection module refers to that the fire detection module detects the smoke and related gas concentrations generated after a fire, and there can be more than one sensor, but must include a fire detection sensor related to gas concentration, and can also include other fire detection sensors, such as temperature sensors, etc. A connector is provided on the fire detection module, and the connector can be electrically connected to the main control board through a cable with a female head. In addition, it can be understood that the embodiments of the present application do not specifically limit the number of gas type fire detection modules, but there is at least one at each of the air outlet and the air inlet.

[0060] In one embodiment, a socket for the power supply and data channel of the smoke sensor that can be connected to the air outlet and the air inlet is provided on the main control board, and the data channel signal of the socket on the main control board is connected to the processor, which can process the data reported by the sensor, and the processor also includes a non-volatile storage module or is connected to a non-volatile storage chip, and can store the data reported by the sensor within a certain period of time.

[0061] In one embodiment, the computer room monitoring system 330 and the network management system 320 are already available in the original system. If the original communication device is not connected to the computer room monitoring system 330, then only the network management system 320 can be reported; if the computer room fire detection module 310 is not connected to the communication device, then there is no need to additionally equip an interface for connection.

[0062] In one embodiment, the main control board collects and stores the data reported by each detection source, and judges whether to report an alarm based on the collected data. The chip on the main control board for processing the data reported by the sensor can be a CPU, an IPMC, or a programmable logic device such as an FPGA / CPLD. In addition, a socket that can be connected to the processor is required on the main control board.

[0063] In one embodiment, the connection between the fire detection module and the main control board is realized by a cable with female connectors at both ends respectively connected to the sockets on the fire detection module and the main control board.

[0064] Based on the hardware structures of the fire detection systems in the above various embodiments, the following presents the various embodiments of the fire detection method of the present application respectively.

[0065] As Figure 2 shown, Figure 2 is a flowchart of the fire detection method provided by an embodiment of the present application; this fire detection method can be applied to the monitoring module in the fire detection system of the above embodiment, and can include but is not limited to step S210, step S220, and step S230.

[0066] Step S210: Obtain the first detection data of the first fire detection module and the second detection data of the second fire detection module;

[0067] Step S220: Compare the first detection data and the second detection data to obtain a comparison result, where the comparison result is a concentration comparison result or a reception time comparison result;

[0068] Step S230: Determine the fire location according to the comparison result.

[0069] In one embodiment, the first fire detection module can detect the air at the air inlet of the communication device to generate the first detection data, and send the first detection data to the monitoring module; in addition, the second fire detection module can detect the air at the air outlet of the communication device to generate the second detection data, and send the second detection data to the monitoring module; then, after receiving the first detection data and the second detection data, the monitoring module will compare the first detection data and the second detection data to obtain a comparison result, and determine the fire location according to the comparison result.

[0070] It should be noted that since the embodiments of the present application can determine whether the fire location is inside or outside the communication device by comparing the first detection data at the air inlet and the second detection data at the air outlet, it can determine whether its own communication device catches fire, and then can decide whether the service continues or is interrupted, avoiding the interruption of the services of all devices in the computer room being affected; in addition, if the fire location is inside the communication device, the embodiments of the present application can also detect the fire situation at an extremely early stage, thus avoiding greater losses.

[0071] Note that regarding the above comparison results, when both the first detection data and the second detection data are concentration data, it may refer to the concentration comparison result between the first detection data and the second detection data; alternatively, it may also refer to the comparison result of the reception times when the monitoring module receives the first detection data and the second detection data respectively. The embodiments of the present application do not make specific limitations on the above comparison results.

[0072] It can be understood that regarding the above fire location, it may be inside the communication device or outside the communication device. The embodiments of the present application do not make specific limitations on this.

[0073] Note that regarding the triggering scenario for comparing the first detection data and the second detection data in the above step S220, it may include but is not limited to Figure 3 or Figure 4 the embodiments shown below, which are specifically as follows:

[0074] As Figure 3 shown, Figure 3 is a flowchart of a fire detection method provided by another embodiment of the present application. Regarding the comparison of the first detection data and the second detection data in the above step S220, it may include but is not limited to step S310 and step S320.

[0075] Step S310: Determine that the difference between the real-time data and the historical data of each type in the first detection data or the second detection data reaches a preset value;

[0076] Step S320: Compare the first detection data and the second detection data.

[0077] In one embodiment, first, the embodiments of the present application can read the historical data of the first detection data or the second detection data and use this as a judgment benchmark; then, the embodiments of the present application read the real-time data of each type in the first detection data or the second detection data and calculate the difference between the real-time data and the historical data; if the difference is greater than or equal to the preset value, it indicates that there may be a fire at this time, and then the embodiments of the present application will start to compare the first detection data and the second detection data.

[0078] It should be noted that if only one type is included in the first detection data or the second detection data, for example, the first detection data or the second detection data is only the data detected by a gas-type detection sensor, then the real-time data of each type mentioned above specifically refers to the real-time data of this one type. Additionally, if two or more types are included in the first detection data or the second detection data, for example, both the first detection data and the second detection data include the data detected by a gas-type detection sensor and the data detected by an optoelectronic-type detection sensor, then the real-time data of each type mentioned above refers to the real-time data of these two types.

[0079] It can be understood that regarding the above-mentioned preset value, it can be set in advance, and the present application embodiment does not specifically limit the numerical size of the preset value.

[0080] As Figure 4 shown, Figure 4 is a flowchart of a fire detection method provided by another embodiment of the present application. Regarding the comparison of the first detection data and the second detection data in step S220 above, it may include but is not limited to step S410 and step S420.

[0081] Step S410: Determine that an alarm signal is received from the computer room fire detection module;

[0082] Step S420: Compare the first detection data and the second detection data.

[0083] In one embodiment, in one embodiment, first, if the monitoring module receives an alarm signal from the computer room fire detection module, it indicates that there is a fire in the computer room. In this regard, in order to determine whether the fire location is inside or outside the communication device, the present application embodiment needs to compare the first detection data and the second detection data.

[0084] Additionally, as Figure 5 shown, Figure 5 is a flowchart of a fire detection method provided by another embodiment of the present application. When both the first fire detection module and the second fire detection module include a gas-type detection sensor and an optoelectronic-type detection sensor, the fire detection method of the present application embodiment further includes but is not limited to step S510, step S520, and step S530.

[0085] Step S510: When the difference between the real-time data of only a single type in the first detection data and the second detection data and the historical data reaches the preset value, obtain the detection status of the gas-type detection sensor and the optoelectronic-type detection sensor;

[0086] Step S520: When the difference between the real-time data and the historical data of only the optoelectronic detection sensor reaches the preset value, generate a dust warning message and an inspection warning message for inspecting the gas detection sensor.

[0087] Step S530: When the difference between the real-time data and the historical data of only the gas detection sensor reaches the preset value, generate an inspection warning message for inspecting the gas detection sensor.

[0088] In an embodiment, the first detection data or the second detection data includes more than two types. For example, both the first detection data and the second detection data include the data detected by the gas detection sensor and the data detected by the optoelectronic detection sensor. If the difference between the real-time data and the historical data of the optoelectronic detection sensor is greater than or equal to the preset value, but the difference between the real-time data and the historical data of the gas detection sensor is less than the preset value, then at this time, a dust warning message and an inspection warning message will be generated in response to inform the user that the gas detection sensor needs to be cleaned or inspected. If the difference between the real-time data and the historical data of the gas detection sensor is greater than or equal to the preset value, but the difference between the real-time data and the historical data of the optoelectronic detection sensor is less than the preset value, then at this time, only an inspection warning message will be generated in response to inform the user that the gas detection sensor needs to be inspected.

[0089] In addition, as Figure 6 shown, Figure 6 is a flowchart of a fire detection method provided by another embodiment of the present application. The first detection data includes a first analog signal, and the second detection data includes a second analog signal. When the monitoring module includes an analog-to-digital converter, regarding determining the fire location according to the comparison result in the above step S230, it may include, but is not limited to, steps S610, S620, and S630.

[0090] Step S610: Convert the first analog signal and the second analog signal through the analog-to-digital converter to obtain first concentration data and second concentration data respectively, where both the first concentration data and the second concentration data include smoke concentration or gas concentration.

[0091] Step S620: When the second concentration data is greater than the first concentration data, determine that the fire location is inside the communication device.

[0092] Step S630: When the second concentration data is less than or equal to the first concentration data, determine that the fire location is outside the communication device.

[0093] In one embodiment, when the monitoring module includes an analog-to-digital converter, the monitoring module can perform analog-to-digital conversion on the first analog signal and the second analog signal through the analog-to-digital converter, so as to obtain the first concentration data of the air inlet and the second concentration data of the air outlet; then, the monitoring module will compare the first concentration data of the air inlet and the second concentration data of the air outlet. Since the air passes through the communication device internally and then is discharged from the air outlet, if the second concentration data is greater than the first concentration data, it indicates that the detected concentration increases after passing through the communication device internally. In this case, it can be considered that the fire location is inside the communication device; if the second concentration data is less than or equal to the first concentration data, it indicates that the detected concentration does not increase after passing through the communication device internally. In this case, it can be considered that the fire location is outside the communication device.

[0094] It should be noted that the above first concentration data and second concentration data may refer to smoke concentration, gas concentration, or other concentrations. The embodiments of the present application do not specifically limit the types of the first concentration data and the second concentration data.

[0095] In addition, as Figure 7 shown, Figure 7 is a flowchart of a fire detection method provided by another embodiment of the present application. The first detection data includes a first alarm digital signal, and the second detection data includes a second alarm digital signal; when the monitoring module does not include an analog-to-digital converter, for determining the fire location according to the comparison result in step S230 above, it may include but is not limited to step S710, step S720, and step S730.

[0096] Step S710: Determine the first reception time of the first alarm digital signal and the second reception time of the second alarm digital signal;

[0097] Step S720: When the first reception time is later than the second reception time, determine that the fire location is inside the communication device;

[0098] Step S730: When the first reception time is earlier than the second reception time, determine that the fire location is outside the communication device.

[0099] In one embodiment, when the monitoring module does not include an analog-to-digital converter, since the monitoring module cannot convert the alarm digital signal into concentration information, in this case, the monitoring module can judge the fire location by the first reception time of receiving the first alarm digital signal and the second reception time of receiving the second alarm digital signal.

[0100] If the first reception time is later than the second reception time, it indicates that the second fire detection module at the air outlet can detect abnormalities faster. Since the air at the air outlet directly comes from the inside of the communication device, while the air at the air inlet directly comes from the outside of the communication device, it can be considered that the fire location is inside the communication device; if the first reception time is earlier than the second reception time, it indicates that the first fire detection module at the air inlet can detect abnormalities faster. Since the air at the air inlet directly comes from the outside of the communication device, while the air at the air outlet directly comes from the inside of the communication device, it can be considered that the fire location is outside the communication device.

[0101] In addition, as Figure 8 shown, Figure 8 FIG. is a flowchart of a fire detection method provided by another embodiment of the present application. After determining that the fire location is inside the communication device, the fire detection method of the embodiment of the present application further includes but is not limited to step S810, step S820, and step S830.

[0102] Step S810: Generate device fire information and send the device fire information to the computer room monitoring system;

[0103] Step S820: Generate power-off notification information and send the power-off notification information and the device fire information to the network management system;

[0104] Step S830: Control the communication device to stop running with regional power-off or stop running with overall power-off.

[0105] In one embodiment, after determining that the fire location is inside the communication device, the monitoring module responds to generate device fire information and power-off notification information, sends the device fire information to the computer room monitoring system, and sends the power-off notification information and the device fire information to the network management system; in addition, the embodiment of the present application also controls the communication device to stop running with regional power-off or stop running with overall power-off.

[0106] In addition, as Figure 9 shown, Figure 9 FIG. is a flowchart of a fire detection method provided by another embodiment of the present application. After determining that the fire location is inside the communication device, the fire detection method of the embodiment of the present application further includes but is not limited to step S910 and step S920.

[0107] Step S910: Obtain the board temperatures of each board in the communication device;

[0108] Step S920: Determine the suspected fire board from multiple boards according to all the board temperatures.

[0109] In one embodiment, after determining that the fire starting position is inside the communication device, the embodiments of the present application can detect the board temperatures of each board inside the communication device through temperature sensors. Then, determine the board with the highest temperature from all the board temperatures, and consider the board with the highest temperature as the suspected fire starting board.

[0110] In addition, as Figure 10 shown, Figure 10 is a flowchart of a fire detection method provided by another embodiment of the present application. After determining that the fire starting position is outside the communication device, the fire detection method of the embodiments of the present application further includes but is not limited to step S1010 and step S1020.

[0111] Step S1010: Obtain the fire starting device corresponding to the fire starting position;

[0112] Step S1020: Control the operating state of the communication device according to the distance between the communication device and the fire starting device.

[0113] In one embodiment, after determining that the fire starting position is outside the communication device, the embodiments of the present application can determine the position where the fire starting device is located, calculate the distance between the communication device and the fire starting device, and then control the operating state of the communication device according to the size of the distance between the two.

[0114] In addition, as Figure 11 shown, Figure 11 is a flowchart of a fire detection method provided by another embodiment of the present application. Regarding controlling the operating state of the communication device according to the distance between the communication device and the fire starting device in the above step S1020, it can include but is not limited to step S1110, step S1120, and step S1130.

[0115] Step S1110: Determine the distance between the communication device and the fire starting device;

[0116] Step S1120: When the distance between the communication device and the fire starting device is greater than or equal to the preset distance, keep the communication device running continuously;

[0117] Step S1130: When the distance between the communication device and the fire starting device is less than the preset distance, control the communication device to stop running.

[0118] In one embodiment, after calculating the distance between the communication device and the fire starting device, if the distance between the communication device and the fire starting device is greater than or equal to the preset distance, it indicates that the communication device will not be affected by the fire. At this time, the communication device can be kept running continuously; if the distance between the communication device and the fire starting device is less than the preset distance, it indicates that the communication device may be affected by the fire. At this time, it is necessary to control the communication device to stop running.

[0119] It is understandable that the preset distance mentioned above can be set in advance, and the embodiments of the present application do not specifically limit the value of the preset distance.

[0120] Based on the fire detection methods of the above embodiments, the overall embodiments of the fire detection method of the present application are respectively proposed below.

[0121] As Figure 12 shown, Figure 12 is the overall step flowchart of the fire detection method provided by an embodiment of the present application; the overall process includes but is not limited to the following steps:

[0122] Step S1201: The smoke sensors located at the air outlet and the air inlet upload data to the main control board in real time;

[0123] Step S1202: The main control board records the data uploaded by the smoke sensors at the air outlet and the air inlet in the memory at regular intervals and saves all records for a relatively long period of time;

[0124] Step S1203: The main control board compares the difference between the real-time uploaded data and the past data to determine whether the real-time data has changed beyond the threshold. If not, it returns to steps S1201 and S1202 to continue monitoring and record saving. If so, it executes step S1205. When the equipped fire detection module has both a photoelectric type and a gas adsorption type smoke sensor, if only one of the data changes, step S1203 is executed;

[0125] Step S1204: If there is an alarm signal from the fire detection module of the computer room connected to the communication device, this signal will also trigger step S1205;

[0126] Step S1205: Compare the data difference between the air outlet and the air inlet. If the smoke / gas concentration at the air outlet is greater than that at the air inlet, it indicates that a fire has occurred inside the equipment, and it proceeds to step S1206. Otherwise, it proceeds to step S1210;

[0127] Step S1206: When a fire is detected inside the communication device, report it to the computer room monitoring system and inform the network management system that this device is about to stop running due to a fire;

[0128] Step S1207: After reporting in the first time, read the temperatures of each single board;

[0129] Step S1208: According to the temperature of each single board, prompt the computer room monitoring system about the possible unit on fire;

[0130] Step S1209: Cut off the power supply of the device to stop running;

[0131] Step S1210: Report a fire in the system computer room when the fire does not occur in this device;

[0132] Step S1211: When this embedded system is installed in each device in the computer room, the distance between this device and the fire - starting device can be judged according to the algorithm. If it is far from this device and will not be in danger of fire temporarily, go to Step S1212; otherwise, go to Step S1209;

[0133] Step S1212: The device continues to run;

[0134] Step S1213: Judge which type of smoke sensor does not change. If the photoelectric - type changes and the gas - type sensor does not change, execute S1214; otherwise, execute Step S1215;

[0135] Step S1214: Send a dust warning and a gas - type sensor inspection warning to the computer room monitoring system;

[0136] Step S1215: Send a gas - type sensor inspection warning to the computer room monitoring system.

[0137] According to the above - mentioned fire detection method embedded in the communication device, the fire detector module identifies whether a fire occurs by detecting the thick smoke generated in the ignition stage of electronic devices, and the module can be customized from a specialized sensor manufacturer according to the specific situation of the device and the environment where it is located.

[0138] In an embodiment, the algorithm for judging the difference between the real - time uploaded data and the past data in Step S1203 is different according to the used fire detection module and the environment. It can be simply comparing the real - time data with the average value of the past data, or making a judgment after removing the outliers. Here, the algorithm is not unique. And the threshold standard for the change of sensor data in Step S1203 also needs to set specific thresholds in combination with the specific sensor and the device environment. The time interval for recording data and the storage time can both be changed according to the specific situation. And the algorithm for judging whether a fire occurs based on the data reported by the sensor is not limited to the above steps and can be changed according to the specific module. That is: the specific algorithm for whether a fire occurs in the software is determined according to the specific application situation.

[0139] Furthermore, the power - off and stop operation in Step S1209 can be divided into zoned power - off or whole - device power - off according to the characteristics of the device itself in implementation.

[0140] As above, the embodiments of this application have the following advantages:

[0141] First, in the event of a fire in this device, the fire can be detected at the initial stage of the fire and extinguished in a timely manner. At the same time, power-off protection is carried out inside the communication device. The combination of these two measures can prevent the fire from spreading outside the device and endangering other devices in the computer room, minimizing the losses.

[0142] Second, in the case of a fire not in this device, the fire detection system embedded in the communication device enables it to identify whether it is on fire itself, maximizing the normal operation of the device without affecting the business. In the later review of the fire situation in the computer room, the alarm logs of the device and the recorded changes in smoke concentration can help locate the specific cause of the fire.

[0143] Third, this system is applicable to all communication devices with air inlets and outlets. It can not only be applied to newly developed devices, but also the transformation cost of old devices is very low and simple. In terms of hardware, there are usually reserved interfaces on the single board of the communication device for debugging, and these interfaces can be used to connect smoke sensors. In terms of software, there is no need to develop a new interface, and only an alarm condition and a corresponding pop-up window need to be added.

[0144] Fourth, in the embodiments of this application, both a light-sensitive smoke sensor and a gas-adsorbing smoke sensor are selected. Using two different-principle smoke sensors together can improve the detection accuracy.

[0145] In one embodiment, taking the common smoke sensor QT-MQ-2 on the market as an example, refer to Figure 13 to illustrate how the fire detection module is embedded in the communication device. Among them, Figure 13 is a schematic diagram of the installation structure of the fire detection module provided by an embodiment of this application inside the communication device.

[0146] The QT-MQ-2 includes a gas detection part composed of a gas-sensitive element and a thermocouple, a potentiometer for adjusting the alarm threshold, and a socket for external connection. The entire detection module is fixed on the fan board with screws, and the main control board is also welded to the socket connected to the processor. Finally, the detection module is connected to the main control board with a cable with female heads at both ends.

[0147] The above completes the work on the hardware aspect required by this system. For the software aspect, the fire detection module is designed according to the Figure 12 flowchart, but the specific thresholds involved, the time for saving data, and the interval time can all be changed according to specific situations. The execution steps at the software level are described according to the situation where the connected smoke sensor is QT-MQ-2:

[0148] In one embodiment, after the sensor data of the air inlet and outlet is reported in real time in step S1201, step S1202 is executed every 10 minutes to store the data at that time point. If it exceeds 24 hours, the data within 24 hours is used as the average value for judgment. If it does not exceed 24 hours, the average value of all data within the recorded time is used for judgment. Step S1203: After the real-time data obtained by the processor of the main control board through the ADC channel is converted into the smoke concentration, when it is found that the smoke concentration is more than twice the previous average value. Immediately execute step S1205: Judge whether the smoke concentration at the air outlet is greater than that at the air inlet. When the judgment is yes, execute step S1206 to report to the network management system or the computer room environment monitoring system, and a prompt window pops up on the interaction interface. The steps before step S1206 are all run in the processor on the single board and are not reflected on the interaction interface. After step S1206, execute step S1207 to try to read the temperatures of all in-place single boards and report the slot where the single board with the highest temperature is located, and remind through a pop-up window. After the pop-up window reminder, the device shuts down immediately. If the judgment in step S1205 is otherwise, execute S1210 to report the fire in the computer room through a pop-up window, and the device continues to run.

[0149] In one embodiment, the embodiments of the present application may not alarm by detecting the smoke concentration after the fire or gases such as carbon dioxide generated after combustion, but may remind the possibility of fire in the device and the computer room by detecting the concentration of flammable gases at the air inlet and outlet.

[0150] In one embodiment, the computer room monitoring system and the network management system for reporting alarms can be combined into one, that is, the network management system also has the function of computer room monitoring.

[0151] In one embodiment, the channel without a socket can be directly connected to a processor under suitable conditions, and the connection from the socket on the main control board to the processor is realized through a flying wire or the flying wire is directly welded from the fire detection module to the processor module of the main control board.

[0152] In one embodiment, if the processor chip of the single board does not have an available ADC channel or is not connected with a non-volatile storage chip, it is judged whether the device catches fire by which party of the smoke sensors at the air inlet and outlet first transmits an alarm digital signal.

[0153] In one embodiment, the data of the fire detection module can also be reported to other single boards, and then reported by the main control board to the network management. Or the newly developed communication device can reserve a slot for the device operation status monitoring unit, and the data of the fire detection module can also be reported to this unit, and this unit is responsible for reporting.

[0154] In one embodiment, in the case of only one smoke alarm, the temperature of each single board is combined to judge whether there is a fire inside.
