At present, common fire alarm means include manual inspection, point smoke detection, linear light beams, flame detectors, image detectors and the like, wherein the manual inspection has high accuracy but low efficiency, and inspectors are easy to fatigue in the inspection process; point type smoke sensation and linear light beams have fixed sensitivity, and usually the smoke is very large, so that an alarm signal can be sent out only when a fire continuously burns for a certain time; fire detectors and image detectors usually identify a fire to a certain extent and send out an alarm signal.

In general, in the field of fire protection of electromechanical devices corresponding to urban rail transit, although the existing fire alarm system can perform early warning or alarm according to the specific development stage of a fire, the existing fire alarm system is limited by the environmental conditions of the electromechanical devices, so that the early fire hazard of the electromechanical devices of the urban rail transit is difficult to be accurately early warned effectively.

Detailed Description

The present application is described in further detail below with reference to figures 1-8.

The embodiment of the application discloses an electromechanical device fire early warning method, which comprises the following steps:

s101, obtaining particulate matters and gas components in an air sample;

s102, detecting the particles to obtain the corresponding particle diameters;

s103, judging whether the diameter of the particulate matter is within the range of the diameter threshold of the smoke particles;

and S108, identifying the type of the electromechanical equipment, matching and generating a corresponding early warning signal according to the corresponding electromechanical equipment information.

The air sample in step S101 is an air data sample in an area of the electromechanical device corresponding to the urban rail transit, where the air data includes a gas type and particulate matter existing in the air.

It should be noted that, the air sample can continuously extract the air in the electromechanical device region through the sampling tube by using the air pump, and the gas components and the particulate matters in the air are analyzed by using the LED dual-light source detection technology.

Further, the electromechanical device belongs to an electrical fire, and in order to early warn the electromechanical device of an early fire, the condition and the development process of the fire of the electromechanical device need to be analyzed. Substance combustion is divided into three stages: pyrolysis, smoldering and open fire, which are mainly characterized by the release of gas and aerosol, commonly called smoke, which is fine particles suspended in air, are generated in the early stages of a fire, and the pyrolysis and smoldering of conventional substances inevitably generate aerosol.

Among them, electrical fires are generally caused by the thermal energy released by electrical lines, consumers, appliances and power supply and distribution equipment in a fault, such as high temperature, electric arcs, electric sparks and non-fault release of thermal energy to generate pyrolytic particles. The pyrolysis particles are particles decomposed when the substances are heated, the particles are minimum substance organization components which can exist in a free state, and no matter what reason, an electrical fire disaster is caused, the particles are reflected in conductor heating, for example, the main heating bodies of electrical faults occurring in a low-voltage power distribution cabinet are electric wires and protective electric appliances, and the particles decomposed by heating in the low-voltage power distribution cabinet are smoke particles and gas particles. When the substance reaches or exceeds the tolerance temperature of the substance, the substance is still in the physical change stage and releases a large amount of particles without chemical reaction with oxygen and the like, and the particles are diffused in the air through Brownian motion and diffusion to form transient particles, and the transient particles are generated because any substance is continuously heated and over-limited due to over-heating, and can be developed towards the combustion stage.

Furthermore, dust (micro dust) with a diameter in the range of 1-100 μm is generally obtained from relevant particulate data, and is generally non-combustion-discharged dust particles such as physically broken solid micro dust, wind-blown dust, wind sand and the like; smoke, generally 0.01-1 μm in diameter, is formed by condensation of vapors produced by sublimation, distillation, melting, chemical reactions, and the like, often oxides; ash, with a diameter in the range of 1-200 μm, being an incombustible particulate produced during combustion; the smoke is solid-liquid mixed aerosol with the diameter of 0.001-2 μm.

From the above, in the early stage of fire of the electromechanical device, generally, the heat energy released by the electromechanical device line causes the line rubber or plastic casing to generate high temperature, so as to generate toxic gas and aerosol, i.e., smoke, and in order to distinguish from dust and water vapor in the air, the diameter of the particulate matter in the air can be detected, wherein the diameter range of the smoke is the diameter threshold range of the smoke particles in step S103.

According to the particle light scattering theory, when the incident light power is constant, the scattering light intensity of the particles changes along with the factors such as particle size and wavelength, the light sources with different wavelengths are adopted, the scattering light intensity of the particles with different particle sizes is different, wherein the particle size of aerosol such as water vapor and dust is far larger than the average particle size of pyrolysis of most other substances, and the identification of non-fire smoke such as water vapor or dust is realized.

For example, an active detection technology and an LED dual-light source detection technology can be adopted, an air pump is used to continuously pump air for effective analysis, and according to the high-power red-blue light LED dual-light source detection technology, the scattering intensity difference between smoke and tiny dust particles by a light source and complex data analysis and processing are performed to determine whether the smoke particles are smoke particles generated by a real fire hazard.

Furthermore, the particle size of the air particulate matters can be identified and detected through the dust particle counter, and the working principle is as follows: the light from the light source is focused in the measuring cavity by the lens group, when each particle in the air rapidly passes through the measuring cavity, the incident light is scattered once to form a light pulse signal, the light signal is sent to the light detector by the lens group and is converted into an electric pulse signal in proportion, the required signal is picked out after the amplification and the discrimination of an electronic circuit of an instrument, the signal is displayed by a counting system, when suspended particles in the sampling gas pass through a light beam generated by a laser light source lamp, the light scattering occurs, the light signal is converted into the pulse signal by the photoelectric converter, and the larger the pulse signal is, the larger the particle size is.

For example, the diameter of the particulate matter in the air sample detected by the above technique is in the range of 0.001-2 μm, and it can be determined that the diameter of the particulate matter meets the corresponding smoke particle diameter threshold range, i.e. smoke diameter threshold range, and then a specific gas type is obtained according to the gas component in the air sample.

For another example, if the diameter of the particulate matter in the air sample detected by the above technique is within the range of 1-100 μm, it can be determined that the diameter of the particulate matter does not conform to the corresponding threshold range of the diameter of the flue gas particulate matter, and the system continues to control the air pump to pump air.

Furthermore, in the early stage of fire of the electrical equipment, due to the high temperature on the surface of the line equipment, corresponding toxic gases are generated, for example, when the cable is in a high temperature state, burnt odor gas is generated, mainly hydrocarbon and benzene gases after rubber decomposition, namely the type of the electrical fire gas in step S105, and certain sulfur-containing organic compounds, and the burnt odor mainly contains sulfur and benzene compounds, so that the gas components in the air are mainly hydrocarbon and benzene gas types, and at this time, the hydrocarbon and benzene gas types account for 95% -98% of the gas components, namely, the ratio of the electrical fire gas in step S105 is within a threshold range.

For example, if the gas component obtained by the gas component detection device is mainly a hydrocarbon gas type and a benzene gas type, the gas can be determined to correspond to the corresponding electric fire gas type, the target specific gravity of the hydrocarbon gas type and the benzene gas type in the gas component is calculated to be 96%, the range of the available electric fire gas specific threshold value is 95% to 98%, and the target specific gravity of the hydrocarbon gas type and the benzene gas type in the gas component can be determined to correspond to the range of the corresponding electric fire gas specific threshold value.

For another example, the gas component detection device detects that the obtained gas components are mainly hydrocarbon and benzene gas types, the target specific gravity of the hydrocarbon and benzene gas types in the gas components is calculated to be 20%, and the gas component detection device can determine that the target specific gravity of the hydrocarbon and benzene gas types in the gas components does not meet the corresponding electric fire gas proportion threshold range, and then the gas component detection device continues to obtain the gas types in the detected air sample.

Further, in order to reduce the occurrence of early fire false alarm of the electromechanical device, on the basis that the target specific gravity corresponding to the gas type is within the range of the gas proportion threshold of the electrical fire, the device operation parameter corresponding to the electromechanical device is obtained, the electromechanical device refers to the electromechanical device in the preset electromechanical device monitoring area, the device operation parameter refers to the operating parameter when the electromechanical device operates, the device operation parameter can be obtained through an operating parameter monitoring system of the electromechanical device, whether the device operation parameter meets the corresponding device operation parameter standard, namely the operating parameter standard when the electromechanical device operates normally is further judged, and if not, the operation of the electromechanical device is abnormal.

For example, through detection of the air sample detection system, the particle diameter in the air sample in the equipment region of the light rail power supply system meets the corresponding smoke particle threshold range, the gas type meets the gas type of the electrical fire, and the target specific gravity of the gas type is also within the gas proportion threshold range of the electrical fire, so that the current parameter of the power supply line equipment in the light rail power supply system, namely the equipment operation parameter, is further obtained.

Wherein, if the normal operation current corresponding to the current parameter of the power supply line equipment is 600-800A, namely the equipment operation parameter standard in step S107, and the current parameter of the power supply line in the light rail power supply system is 1200A obtained by the monitoring system of the working parameter of the power supply line equipment, the equipment operation parameter corresponding to the power supply line equipment is judged not to conform to the corresponding equipment operation parameter standard,

in order to facilitate the troubleshooting of the abnormal electromechanical device, the electromechanical device type corresponding to the power supply line device is further obtained, the electromechanical device type refers to a specific device type of the electromechanical device, for example, the electromechanical device type corresponding to the power supply line device is a light rail third rail power supply device type, the electromechanical device type is further identified and is matched with corresponding electromechanical device information to generate a corresponding early warning signal, and the electromechanical device information refers to specific connection position information of the electromechanical device type.

For another example, if the current parameter of the power supply line in the light rail power supply system is 700A obtained by the power supply line equipment working parameter monitoring system, it can be determined that the equipment operating parameter corresponding to the power supply line equipment meets the corresponding equipment operating parameter standard, and at this time, the power supply line equipment working parameter monitoring system continues to monitor the working parameter of the light rail power supply system.

The early stage of fire disaster of the electromechanical equipment generally generates dense smoke particles and toxic gas, whether the particles in the air sample are in the range of the diameter threshold of the smoke particles is judged firstly because the judgment characteristics of the particles diffused in the air are obvious in the early pyrolysis and smoldering stage of the fire disaster of the electromechanical equipment, the early fire hazard of the electromechanical equipment is identified by combining the target specific gravity characteristics of gas species in gas components immediately, and finally, in order to reduce the occurrence of false alarm conditions, the running condition of the electromechanical equipment is further detected, whether abnormal running occurs or not, so that the early fire disaster of the electromechanical equipment can be analyzed and judged more accurately.

In the fire early warning method for the electromechanical device, if the diameter of the particulate matter in the air sample is within the range of the threshold value of the diameter of the smoke particulate matter corresponding to the particulate matter volatilized when the line of the electromechanical device is at a high temperature, it is indicated that the electromechanical device has a corresponding fire hazard, further, if the gas type corresponding to the gas component in the air sample meets the gas type of the electrical fire and the corresponding target specific gravity also meets the range of the threshold value of the gas proportion of the electrical fire, it is further indicated that the electromechanical device has a related fire hazard, further, if the device operation parameter corresponding to the electromechanical device does not meet the standard of the device operation parameter corresponding to the electromechanical device, it is indicated that the electromechanical device has an abnormal state and has a fire condition, at this time, the type of the electromechanical device is identified, a corresponding early warning signal is generated according to the information of the electromechanical device, and according to the early warning signal, the worker can have enough time to handle the hidden condition of the fire, and suppress the progress of the fire, thereby improving the accuracy of early warning for the fire of the electromechanical device.

In one embodiment of the present invention, as shown in fig. 2, the step S106 of obtaining the device operation parameters corresponding to the electromechanical device includes the following steps after obtaining the device operation parameters corresponding to the electromechanical device if the target specific gravity of the gas species in the gas component is within the electric fire gas proportion threshold range:

s201, obtaining the surface temperature of the line equipment corresponding to the electromechanical equipment;

s202, judging whether the surface temperature of the line equipment reaches a high-temperature threshold of the electromechanical equipment or not;

s203, if the surface temperature of the line equipment reaches the high-temperature threshold of the electromechanical equipment, judging whether the high-temperature duration corresponding to the surface temperature of the line equipment exceeds the high-temperature operation duration standard or not;

s204, if the high-temperature duration corresponding to the surface temperature of the line equipment exceeds the high-temperature operation duration standard, acquiring the assembly position of the line equipment corresponding to the electromechanical equipment;

and S205, generating a corresponding primary electromechanical device temperature abnormity response signal according to the assembly position of the line device.

In practice, the electrical line allows continuous passage of an amount of current, called safe ampacity or safe current, without overheating the electrical line, and the maximum allowable operating temperature of the line device is typically 65 degrees, i.e. the high temperature threshold of the electromechanical device. When the overload occurs, the line equipment temperature, i.e. the surface temperature of the line equipment, which can be detected by the temperature sensors provided on the electromechanical equipment and the line, exceeds this temperature value, which may cause accelerated aging and even damage of the insulation and cause a short-circuit fire.

For example, if the line device surface temperature obtained by the temperature sensor and corresponding to the third rail power supply device for the light rail is 120 degrees, and the electromechanical device high-temperature threshold value corresponding to the third rail power supply device for the light rail is 120 degrees, it can be determined that the line device surface temperature reaches the corresponding electromechanical device high-temperature threshold value.

For another example, if the line device surface temperature obtained by the temperature sensor and corresponding to the third rail power supply device of the light rail is 111 degrees, it can be determined that the line device surface temperature does not reach the electromechanical device high-temperature threshold, and at this time, the temperature sensor continues to acquire the surface real-time temperature of the third rail power supply device of the light rail.

After the circuit is powered on, the current can generate heat through the electric wire, the connector and the equipment, the normal phenomenon is realized, the connector quality is qualified, the contact resistance is not large, the heating amount of the connection point is small, the normal temperature can be kept, if the connector quality is unqualified, the contact resistance can be increased, the generated heat is more, the heating amount is more when the connector is not qualified, the larger the resistance is, the more the heating amount is, and the surface temperature of the circuit equipment is in a continuous high-temperature state.

In order to reduce the occurrence of the above situations, the high-temperature duration corresponding to the surface temperature of the line equipment is further monitored and obtained, and whether the high-temperature duration exceeds a corresponding high-temperature operation duration standard is judged, where the high-temperature operation duration standard refers to a safe duration allowing the surface temperature of the line equipment to be continuously at a high temperature, and if the high-temperature operation duration exceeds the high-temperature operation duration standard, the rubber or the insulating layer of the line equipment may be burned.

For example, the surface temperature of the light rail third rail power supply cable has reached the corresponding electromechanical device high-temperature threshold, and it is known that the high-temperature operation duration standard corresponding to the light rail third rail power supply cable is 100 minutes, at this time, the timer obtains that the high temperature on the surface of the light rail third rail power supply cable has lasted for 120 minutes, it can be determined that the high-temperature duration corresponding to the light rail third rail power supply cable exceeds the corresponding high-temperature operation duration standard, the line device assembly position of the light rail third rail power supply cable is obtained, and the corresponding primary electromechanical device temperature abnormality response signal is generated.

For another example, when the surface temperature of the light rail third rail power supply cable reaches the corresponding electromechanical device high-temperature threshold, and the timer acquires that the surface high temperature of the light rail third rail power supply cable lasts for 80 minutes, it can be determined that the high-temperature duration time corresponding to the light rail third rail power supply cable does not exceed the corresponding high-temperature operation duration time standard, and at this time, the temperature sensor continues to acquire the surface real-time temperature of the light rail third rail power supply cable.

According to the electromechanical equipment fire early warning method provided by the embodiment, if the high-temperature duration corresponding to the surface temperature of the line equipment exceeds the high-temperature operation duration standard, the line equipment corresponding to the electromechanical equipment is possible to be burnt due to the high temperature at any time, and then the first-stage electromechanical equipment temperature abnormal response signal is generated by combining the line equipment assembly position corresponding to the line equipment, so that early warning prompt for early fire hidden dangers of the electromechanical equipment is facilitated, and the accuracy of early fire hidden danger early warning for the electromechanical equipment is improved.

In one embodiment of this embodiment, as shown in fig. 3, after generating the corresponding temperature anomaly response signal of the primary electromechanical device according to the installation position of the line device in step S205, the method further includes the following steps:

s301, if the temperature change trend corresponding to the surface temperature of the line equipment is continuously increased, acquiring the heating rate corresponding to the surface temperature of the line equipment;

s302, if the temperature rising rate reaches the abnormal temperature rising rate standard, judging whether a circuit protection mechanism corresponding to the electromechanical equipment is triggered;

and S303, if the line protection mechanism corresponding to the electromechanical equipment is not triggered, generating a corresponding secondary electromechanical equipment temperature abnormal response signal according to the assembly position of the line equipment.

In practical application, under the condition of a certain line current of the electromechanical equipment, the larger the resistance is, the more the heat is generated, so that a line segment with larger contact resistance can generate heat strongly, the temperature is high rapidly, the insulation layer of the conducting wire is burnt, substances such as dust, fibers and the like on the surface of the line are burnt, and a fire disaster can be caused if the substances are not treated properly.

In order to reduce the above situations, it is further determined whether a temperature variation trend corresponding to the surface temperature of the line equipment is continuously increased, if the temperature variation trend is continuously increased, in order to obtain temperature data of the surface of the line equipment in real time, a temperature increase rate corresponding to the surface temperature of the line equipment is detected, and if the temperature increase rate reaches an abnormal temperature increase rate standard, it is indicated that the fire hazard of the line equipment is more severe, and a fire may occur at any time, wherein the abnormal temperature increase rate standard refers to a temperature increase rate condition causing an electrical line fire.

If the temperature rise rate of the surface temperature of the line equipment does not reach the abnormal temperature rise rate standard, the surface temperature of the line equipment is continuously monitored and recorded.

Generally, a line device is provided with a corresponding installation protection device, i.e., a line protection mechanism, such as an emergency cut-off device like a fuse, and at this time, whether the line protection mechanism corresponding to the electromechanical device is triggered is detected, if not, it is indicated that an abnormal fault also occurs in the line protection mechanism, and in order to perform early warning prompt on relevant firefighters in time, a corresponding secondary electromechanical device temperature abnormal response signal is generated according to the assembly position of the line device.

And if the line protection mechanism corresponding to the electromechanical equipment is triggered, the system monitoring system records and tracks the running condition of the line equipment in real time.

According to the fire early warning method for the electromechanical equipment, if the temperature rise rate reaches the corresponding abnormal temperature rise rate standard, it is indicated that the line equipment is in a violent temperature rise stage at the moment, an electrical fire accident occurs at any time, if a line protection mechanism corresponding to the line equipment is not triggered at the moment, the fire influence range can be further expanded, a secondary electromechanical equipment temperature abnormal response signal is generated immediately, the output priority of the secondary electromechanical equipment temperature abnormal response signal is higher than that of the primary electromechanical equipment temperature abnormal response signal, and therefore reasonable early warning can be conducted according to the danger degree of early fire hidden danger of the electromechanical equipment.

In one implementation of this embodiment, as shown in fig. 4, the step S108 of identifying the type of the mechatronic device, and matching and generating the corresponding warning signal according to the corresponding mechatronic device information includes the following steps:

s401, if the number of the electromechanical device types is multiple, matching electromechanical device information corresponding to each electromechanical device type;

s402, judging whether correlation triggering connection exists among a plurality of electromechanical device types according to electromechanical device information;

and S403, if the multiple electromechanical device types are in associated triggering connection, acquiring and generating an early warning signal according to the corresponding target electromechanical device.

In practical application, if there are a plurality of electromechanical device types with high temperature anomaly, a relevance fault may be caused, that is, there is a relevance triggering relationship, that is, relevance triggering connection, between the plurality of electromechanical device types, for example, in an urban rail transit power supply system, it is necessary to reasonably transform a voltage transmitted through a related voltage transformation device, and then transmit a corresponding rated working voltage to each functional module, that is, the electromechanical device type, where the functional module includes an external power supply system, an internal power supply system, a traction power supply system, a power lighting power supply system, and an electric power monitoring system.

For example, there is a correlation triggering connection between the internal power supply system and the traction power supply system, and if the power supply device in the power supply system loses power supply function due to high-temperature abnormality, a fault occurs in the power supply device in the correlation traction power supply system, and a corresponding early warning signal is obtained and generated according to the internal power supply system and the power supply device, i.e., the target electromechanical device, in the traction power supply system.

For another example, if there is no correlation triggering connection between the traction power supply system and the power lighting power supply system, the corresponding high-temperature abnormal electromechanical device in the traction power supply system and the power lighting power supply system is marked to generate a corresponding early warning signal.

The electromechanical device fire early warning method provided by the embodiment can be used for early warning the target electromechanical devices which have early fire hazards and are associated with each other, so that related workers can be prompted to accurately check and eliminate the fire hazards appearing in the target electromechanical devices, and the safety of the electromechanical devices is improved.

In one implementation of this embodiment, as shown in fig. 5, in step S403, that is, if there is an association triggering connection between multiple electromechanical device types, acquiring and generating an early warning signal according to a corresponding target electromechanical device includes the following steps:

s501, if the correlation triggering connection exists among the electromechanical device types, judging whether a corresponding standby device line exists in a connecting line between a target electromechanical device and the target electromechanical device;

s502, if a corresponding standby equipment line exists in a connecting line between the target electromechanical equipment and the target electromechanical equipment, switching to the standby equipment line;

s503, if the corresponding standby equipment line does not exist in the connecting line between the target electromechanical equipment and the target electromechanical equipment, the target electromechanical equipment is shut down, the connecting line between the target electromechanical equipment is cut off, and a corresponding early warning signal is generated according to the connecting line information between the target electromechanical equipment and the target electromechanical equipment.

In practical applications, if there is a correlation triggering connection between multiple electromechanical device types, in general, when an abnormal target electromechanical device occurs, the connection line between the corresponding target electromechanical devices is also affected to a certain extent, and therefore, to further reduce loss, it is determined whether there is a corresponding backup device line in the connection line between the target electromechanical device and the target electromechanical device, and if so, the connection line is directly switched to the corresponding backup device line, where the backup device line refers to a backup device line corresponding to the connection line between the electromechanical device types or the electromechanical device types.

And if the connecting line between the target electromechanical equipment and the target electromechanical equipment does not have a corresponding standby equipment line, shutting down the target electromechanical equipment in order to slow down the development process of the fire, cutting off the connecting line between the target electromechanical equipment, generating a corresponding early warning signal according to the connecting line information between the target electromechanical equipment and the target electromechanical equipment, and according to the early warning signal, the relevant operation and maintenance personnel can know the specific abnormal position of the electromechanical equipment in advance according to the connecting line information between the target electromechanical equipment and the target electromechanical equipment, so that the relevant hidden dangers of the electromechanical equipment can be checked in time.

The system can control the remote resetting, remote fault isolation, alarm threshold modification, event record inquiry printing and the like of the electromechanical equipment according to the abnormal solution list.

According to the electromechanical device fire early warning method provided by the embodiment, if the corresponding standby device line does not exist in the connection line between the target electromechanical device and the target electromechanical device, the corresponding early warning signal is generated according to the corresponding electromechanical device line information, so that related workers can conveniently obtain the connection line information between the target electromechanical device and the target electromechanical device, which are abnormal and have no standby device line, and the efficiency of fire hazard troubleshooting of the electromechanical device is improved.

In one implementation of this embodiment, as shown in fig. 6, identifying the type of the mechatronic device in step S108, and matching and generating the corresponding warning signal according to the corresponding mechatronic device information includes the following steps:

s601, identifying the type of the electromechanical equipment, and acquiring equipment operation parameters corresponding to the type of the electromechanical equipment;

s602, matching equipment operation parameter standards corresponding to the types of the electromechanical equipment according to the equipment operation parameters;

s603, generating a corresponding equipment operation parameter difference by combining the equipment operation parameters and equipment operation parameter standards corresponding to the equipment operation parameters;

s604, generating an operation parameter difference schematic diagram corresponding to the type of the electromechanical equipment according to the operation parameter difference of the equipment;

and S605, generating a corresponding early warning signal according to the operation parameter difference schematic diagram.

In practical application, in order to accurately obtain the real-time operation condition of the abnormal electromechanical device, corresponding device operation parameter differences are generated according to device operation parameters of the abnormal electromechanical device and device operation parameter standards corresponding to the device operation parameters, the device operation parameter standards refer to operation parameters of the electromechanical device in a normal state, and the device operation parameter differences refer to differences between the operation parameters of the electromechanical device in an abnormal state and the operation parameters of the electromechanical device in a corresponding normal state.

For example, the standard of the device operation parameter is 110KV of the line voltage of the power supply system, at this time, the real-time operation voltage of the line of the power supply system, that is, the device operation parameter is 380KV, and the difference of the device operation parameter corresponding to the line of the power supply system is-270 KV.

Further, in order to facilitate displaying of the operation parameter difference corresponding to the abnormal electromechanical device, a corresponding operation parameter difference schematic diagram is generated according to the type of the electromechanical device, namely the type of the electromechanical device, the operation parameter difference schematic diagram is a difference schematic diagram formed by taking the type of the electromechanical device as a group according to the operation parameter difference corresponding to the specific electromechanical device, and the operation parameter difference schematic diagram can be displayed through a monitoring screen of the monitoring center.

According to the electromechanical equipment fire early warning method provided by the embodiment, according to the operation parameter difference schematic diagram, the related working personnel can conveniently and effectively analyze the abnormal electromechanical equipment type and the corresponding operation parameters, and the operation safety of the electromechanical equipment is improved.

In one implementation of this embodiment, as shown in fig. 7, the step S603 of generating the corresponding warning signal according to the schematic diagram of the difference of the operating parameters includes the following steps:

s701, analyzing the operation parameter difference schematic diagram to obtain a corresponding operation parameter difference value;

s702, identifying a difference value of the operation parameters, and setting an early warning priority corresponding to the type of the electromechanical equipment, wherein the difference value of the operation parameters is in direct proportion to the early warning priority;

and S703, generating a corresponding early warning signal according to the early warning priority.

In practical application, the schematic operating parameter difference diagram can be displayed through a monitoring screen of the monitoring center, but if the monitoring center is in a vacant state of a worker, warning cannot be prompted to the worker, at this time, an operating parameter difference value corresponding to the abnormal electromechanical device is obtained according to the schematic operating parameter difference diagram, and the operating parameter difference value refers to the difference between the operating parameter value of the electromechanical device in the abnormal operating state and the operating parameter value of the electromechanical device in the normal operating state.

Further, an early warning priority corresponding to the type of the electromechanical device is set according to the size of the operation parameter difference, wherein the operation parameter difference is in direct proportion to the early warning priority, for example, the device operation parameter standard is 110KV of the line of the power supply system a, 280KV of the line of the power supply system B, at this time, the real-time operation voltage of the line of the power supply system a, i.e., the device operation parameter, is 380KV, the device operation parameter difference corresponding to the line of the power supply system is-270 KV, the real-time operation voltage of the line of the power supply system B, i.e., the device operation parameter, is 500KV, the device operation parameter difference corresponding to the line of the power supply system is-220 KV, the operation parameter difference corresponding to the line of the power supply system a is 270, the operation parameter difference corresponding to the line of the power supply system B is 220, at this time, the early warning priority corresponding to the line of the power supply system a is higher than the early warning priority corresponding to the line of the power supply system B, the early warning signal of the line of the power supply system a is preferentially output, the early warning signal can be set as needed to enable a worker to have enough time to deal with the hidden fire, thereby suppressing the progress of the fire.

According to the fire early warning method for the electromechanical equipment, the early warning priority corresponding to the type of the electromechanical equipment is set according to the difference value of the operation parameters, so that reasonable and standard early warning is conveniently carried out by combining the abnormal operation degree corresponding to the type of the electromechanical equipment, and the troubleshooting efficiency of the abnormal electromechanical equipment is improved.
