Detailed Description
The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
It is noted that the terms "first," "second," and the like in the description and claims of the present disclosure and in the drawings are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order.
Before introducing the method, apparatus, and system for testing smoke sensing function provided by the present disclosure, an application scenario of embodiments of the present disclosure is first introduced. The embodiments of the present disclosure may be used to test the smoke sensing function of a fire alarm system, for example, the smoke sensing function of a fire alarm system of an urban rail transit train, the smoke sensing function of a fire alarm system of a building, and the like.
Taking the smoke sensing function of the fire alarm system of the urban rail transit train as an example, the fire alarm system of the urban rail transit train is taken as an important subsystem of the urban rail transit train, and the normal sensing of smoke is related to the safety of the train. In the correlation technique, carry on electron fog generator and camera through at unmanned aerial vehicle, and then produce smog through this electron fog generator to, through the image information of the smoke alarm ware of this camera collection, whether there is the warning response on the basis of image information sign smoke transducer, confirm whether fire alarm system's smog perception function is normal.
The applicant finds that due to the fact that the types of smoke detectors of the fire alarm system are different and the smoke detectors of the same type have different smoke sensing capabilities, when the smoke sensing function of the fire alarm system is tested, if the smoke concentrations are the same, the alarm response of the fire alarm system to the smoke is often tested to be inaccurate. Moreover, if a smoke detector of the fire alarm system is in line connection with the management server, even if the smoke detector has an alarm response, the position of the alarm response of the management server is inconsistent with the position of the actually tested smoke detector, so that the smoke sensing function of the fire alarm system cannot work normally, and finally the safety of buildings, trains and the like is reduced.
To this end, the present disclosure provides a method for testing smoke perception function, which, with reference to the flow diagram of a method for testing smoke perception function shown in fig. 1, comprises:
s11, controlling an electronic fog generator on the unmanned aerial vehicle to generate smog.
And S12, adjusting the power of the electronic smoke generator for generating smoke based on the smoke alarm response of the fire alarm system to the smoke.
The power of the electronic smoke generator for generating smoke is adjusted, and the electronic smoke generator can generate smoke with different concentrations.
S13, determining a critical power value of the electronic smoke generator, and determining a critical smoke concentration value corresponding to the critical power value according to the corresponding relation between the power of the electronic smoke generator and the smoke concentration.
The critical power value refers to a critical power value for triggering the smoke alarm response of the fire alarm system.
The critical power value is usually the minimum critical power value, namely the electronic smoke generator generates smoke at the minimum critical power value, so that the fire alarm system can have smoke alarm response.
And S14, determining whether the smoke sensing function of the fire alarm system is in a normal working state or not according to the numerical relation between the critical smoke concentration value and the standard alarm range.
When the unmanned aerial vehicle is specifically implemented, the camera can be carried on the unmanned aerial vehicle for collecting the environmental image information around the unmanned aerial vehicle and determining the image information of the smoke detector of the fire alarm system, and the flight state of the unmanned aerial vehicle, such as a flight line and the flight height, can be conveniently controlled.
It can be stated that the smoke alarm response of the fire alarm system to smoke is alarm information sent to an alarm controller or a monitoring management server of the fire alarm system when smoke generated by the electronic smoke generator is sensed by a smoke detector of the fire alarm system. Generally, a smoke detector has a standard alarm range, and when the smoke concentration is within the standard alarm range, the smoke detector can sense smoke and further send out alarm information.
Exemplarily, the critical power value of the electronic smoke generator is determined to be 3.5w, and according to the corresponding relation between the power of the electronic smoke generator and the smoke concentration, the critical smoke concentration value corresponding to the critical power value of 3.5 is determined to be 0.12.
If the critical smoke concentration value exceeds the standard alarm range in value, it is determined that the smoke sensing function of the fire alarm system is not in a normal working state, for example, the critical smoke concentration value is 0.09, and the numerical range of the standard alarm range is 0.1 to 0.15, it is determined that the smoke sensing function of the fire alarm system is not in a normal working state.
And if the critical smoke concentration value is within the standard alarm range, determining that the smoke sensing function of the fire alarm system is in a normal working state, for example, the critical smoke concentration value is 0.12, and the numerical range of the standard alarm range is 0.1-0.15, determining that the smoke sensing function of the fire alarm system is in a normal working state.
According to the technical scheme, the power of the electronic smoke generator for generating smoke is adjusted through the smoke alarm response of the fire alarm system to the smoke, the critical power value of the electronic smoke generator can be determined, the test of smoke detectors with various sensitivities is adapted, and the accuracy of testing the alarm response of the fire alarm system to the smoke is improved. Furthermore, according to the corresponding relation between the power of the electronic smoke device and the smoke concentration, the critical smoke concentration value corresponding to the critical power value is determined, and the critical smoke concentration values of various smoke detectors can be obtained qualitatively. And finally, determining whether the smoke sensing function of the fire alarm system is in a normal working state or not according to the numerical relation between the critical smoke concentration value and the standard alarm range. Therefore, whether the smoke sensing function is in a normal state or not can be tested from the closed loop level of the fire alarm system, and therefore the accuracy and the convenience of testing are improved.
Fig. 2 is a flow diagram illustrating another method for testing smoke perception functionality according to an example embodiment. As shown in fig. 2, the method includes:
s21, determining an initial power value of the electronic smoke generator according to the smoke detector information of the fire alarm system.
The initial power value is used for enabling an electronic smoke generator on the unmanned aerial vehicle to generate smoke according to the initial power value, and the information of the smoke detector comprises the type of the smoke detector and the shape of the smoke detector.
S22, controlling an electronic fog generator on the unmanned aerial vehicle to generate smog according to the initial power value.
And S23, adjusting the power of the electronic smoke generator for generating smoke based on the smoke alarm response of the fire alarm system to the smoke.
And S24, determining a critical power value of the electronic smoke generator, and determining a critical smoke concentration value corresponding to the critical power value according to the corresponding relation between the power of the electronic smoke generator and the smoke concentration, wherein the critical power value is the critical power value for triggering the smoke alarm response of the fire alarm system.
And S25, determining whether the smoke sensing function of the fire alarm system is in a normal working state or not according to the numerical relation between the critical smoke concentration value and the standard alarm range.
In specific implementation, the sensitivity of the smoke detector of the fire alarm system in different areas may be different, and the initial power value of the electronic smoke generator may be determined according to the information of the smoke detector, such as the type of the smoke detector and/or the shape of the smoke detector, so that the number of times of adjusting the power of the electronic smoke generator to generate smoke may be reduced. Whether the smoke sensing function is in a normal state or not is further conveniently tested.
In a possible implementation manner, a database may be established according to the standard alarm range of the smoke detector of the fire alarm system, and a corresponding relationship between the model of the smoke detector and the initial power value or a corresponding relationship between the shape of the smoke detector and the initial power value may be established in the database. Therefore, the initial power value in the database can be matched according to the model or the shape of the smoke detector, and the initial power value of the electronic smoke generator can be conveniently determined. The convenience of testing whether the smoke sensing function is in a normal state is improved.
In another possible implementation manner, smoke detector information can be collected, and an initial power value manually input is received, so that an electronic smoke generator on the unmanned aerial vehicle is controlled to generate smoke according to the initial power value.
Fig. 3 is a flow diagram illustrating another method for testing smoke perception functionality according to an example embodiment. As shown in fig. 3, the method further comprises:
and S31, determining a CPK (Complex Process Capability Index) value of the smoke detector according to the difference value between the critical smoke concentration value and the central value of the standard alarm range.
The CPK value is an index for judging whether a reaction product is qualified, and for a smoke detector, the closer the critical smoke concentration value capable of triggering smoke alarm is to the central value of a standard alarm range specified by the industry, the higher the CPK value of the smoke detector is, the better the product performance is. In addition, since the higher the CPK value, the higher the cost of the product, in practical applications, it is common to adjust the CPK value of the product to be within an acceptable reference value range.
And S32, determining the smoke alarm response consistency of the smoke detector according to the numerical relation between the CPK value and the reference value range.
Specifically, after the critical smoke concentration value of the smoke detector to be detected is determined, the CPK value of the smoke detector is determined according to the difference between the critical smoke concentration value and the central value of the standard alarm range provided by a supplier, for example, the CPK value of the smoke detector is determined to be 1.55, and then according to the reference range of 1.67-2.0, the smoke alarm response consistency of the smoke detector is determined to be not satisfactory, and a part of the smoke detector with a larger difference between the critical smoke concentration value and the central value of the standard alarm range needs to be replaced; if the CPK value of the smoke detector is determined to be 2.2, the smoke detector with lower sensitivity can be considered on the basis of considering safety and cost.
Fig. 4 is a flow diagram illustrating another method for testing smoke perception functionality according to an example embodiment. As shown in fig. 4, the method further comprises:
s41, determining first smoke alarm position information according to the position information of the smoke alarm response of the fire alarm system, and determining second smoke alarm position information according to the position information of the unmanned aerial vehicle.
And S42, determining whether the position information represented by the first smoke alarm position information is consistent with the position information represented by the second smoke alarm position information so as to determine whether the smoke perception of the fire alarm system is consistent.
Specifically, the first position information of the smoke detector with smoke alarm response can be determined through the number information of the smoke detector by the fire alarm system, for example, the corresponding relation between the carriage number and the smoke detector number is established, and when the smoke detector with the number of N1-001 is determined to have smoke sensing alarm information, the smoke detector is determined to be arranged at the position, close to the locomotive, of the carriage 1 through the corresponding relation between the carriage number and the smoke detector number.
Further, the position of the smoke detector tested at the moment is determined according to the position information of the unmanned aerial vehicle. If the position information of the unmanned aerial vehicle represents that the position of the smoke detector tested at the moment is the position of the carriage 1 close to the tail of the vehicle, the smoke perception of the fire alarm system is determined to be inconsistent, namely the smoke detector of the fire alarm system is determined to be in line connection with the management server wrongly.
Therefore, when the position information represented by the first smoke alarm position information is inconsistent with the position information represented by the second smoke alarm position information, the smoke detector of the fire alarm system can be determined to be in line connection with the management server, so that the connection can be changed in time, and the accuracy of the smoke sensing function of the fire alarm system is ensured.
In step S12, adjusting the power of the electronic smoke generator to generate smoke based on the smoke alarm response of the fire alarm system to the smoke, comprising:
if the feedback information of the smoke alarm response of the fire alarm system to the smoke is not received within the preset time, controlling the power of the electronic smoke generator to generate the smoke to be increased; or alternatively
And if feedback information of the smoke alarm response of the fire alarm system to the smoke is received within the preset time, controlling the power of the electronic smoke generator to generate the smoke to be reduced.
Specifically, when the electronic smoke generator on the unmanned aerial vehicle is controlled to continuously generate smoke, feedback information of smoke alarm response of the fire alarm system to the smoke is not received within a preset time, and the fact that the fire alarm system does not respond to the smoke with the concentration is described, the power of the electronic smoke generator for generating the smoke is controlled to be increased. For example, an electronic smoke generator on the unmanned aerial vehicle is controlled to continuously generate smoke, and within 1 minute of preset time, feedback information of smoke alarm response of the fire alarm system to the smoke is not received, so that the power of the electronic smoke generator for generating the smoke is controlled to be increased by 1w. And within 1 minute of the preset time, if no feedback information of the smoke alarm response of the fire alarm system to the smoke is received, controlling the power of the electronic smoke generator to increase by 1w again. And so on.
Accordingly, controlling the electronic smoke generator to produce a reduction in smoke power is not described in detail herein.
Optionally, the value of the increase or decrease of the power of the smoke generated by controlling the electronic smoke generator each time may be different, and the preset time may also be different according to the magnitude of the power.
In step S13, determining a critical power value of the electronic smoke generator comprises:
and taking the power value corresponding to the received feedback information in the two adjacent times of receiving and not receiving the feedback information as the critical power value.
Specifically, if the feedback information of the smoke alarm response of the fire alarm system to the smoke is received in the previous time and the feedback information of the smoke alarm response of the fire alarm system to the smoke is not received in the later time, the power value corresponding to the smoke generated in the previous time is the critical power value; if the feedback information of the smoke alarm response of the fire alarm system to the smoke is not received in the previous time and the feedback information of the smoke alarm response of the fire alarm system to the smoke is received in the next time, the power value corresponding to the smoke generated in the next time is a critical power value.
Optionally, the method further comprises:
and controlling the unmanned aerial vehicle to adjust the position so as to adjust the relative position relation between the smoke outlet of the electronic smoke generator and the smoke detector of the fire alarm system.
The example is ground, gather electron smoke generator's outlet and fire alarm system's smoke detector's image information through the camera, when electron smoke generator's outlet and smoke detector position are improper, can control unmanned aerial vehicle and carry out position control, for example, when the outlet height of electron smoke generator is far away from smoke detector, control unmanned aerial vehicle height suitable rising.
Optionally, a plurality of cameras may be provided at the unmanned aerial vehicle, for example, two cameras are provided, one camera is used for acquiring image information of the flight of the unmanned aerial vehicle, and the other camera is used for acquiring image information of a smoke outlet of the electronic smoke generator and a smoke detector of the fire alarm system. Thus, the operation of controlling the rotation of the camera can be reduced. The flying state of the unmanned aerial vehicle is prevented from being adjusted, the relative position relation between the smoke outlet of the electronic smoke generator and the smoke detector of the fire alarm system is observed, and the camera is controlled to rotate back and forth repeatedly.
