Detailed ways

Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

It should be noted that the terms "first" and "second" in the specification, claims and drawings of the present disclosure are used to distinguish similar objects, and are not necessarily interpreted as describing a specific sequence or sequence.

Before introducing the method, device and system for testing the smoke perception function provided by the present disclosure, the application scenarios of the embodiments of the present disclosure are firstly introduced. Various embodiments of the present disclosure can 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 perception function of the fire alarm system of urban rail transit trains as an example, the fire alarm system of urban rail transit trains is an important subsystem of urban rail transit trains, and its normal perception of smoke is related to the safety of trains. In the related technology, an electronic smog generator and a camera are installed on the drone, and then the electronic smog generator generates smoke, and the image information of the smoke alarm collected by the camera is used to characterize whether the smoke sensor has an alarm based on the image information. Response to determine if the smoke sensing function of the fire alarm system is functioning properly.

The applicant found that due to the different models of smoke detectors in the fire alarm system and the differences in the ability of the smoke detectors of the same model to perceive smoke, when testing the smoke sensing function of the fire alarm system, if the smoke concentration is the same, it often leads to the test of the fire alarm system. The alarm response to the smoke was inaccurate. Moreover, if the smoke detector of the fire alarm system is connected incorrectly to the management server, even if the smoke detector responds to the alarm, the location of the alarm response from the management server is inconsistent with the location of the actually tested smoke detector, causing the fire alarm system to fail. The smog sensing function of the device does not work properly, which eventually leads to a decrease in the safety of buildings, trains, etc.

To this end, the present disclosure provides a method for testing the smoke sensing function, referring to a schematic flowchart of a method for testing the smoke sensing function shown in FIG. 1 , the method includes:

S11. Control the electronic smoke generator on the drone to generate smoke.

S12. Adjust the smoke generating power of the electronic smoke generator based on the smoke alarm response of the fire alarm system to the smoke.

Wherein, by adjusting the power of the electronic smoke generator to generate smoke, the electronic smoke generator can generate smoke with different concentrations.

S13. Determine the critical power value of the electronic smoke generator, and determine the critical smoke concentration value corresponding to the critical power value according to the correspondence between the power of the electronic smoke generator and the smoke concentration.

Wherein, the critical power value refers to a critical power value that triggers a smoke alarm response of the fire alarm system.

The critical power value mentioned here usually refers to the minimum critical power value, that is, the electronic smoke generator generates smoke at the minimum critical power value, which can make the fire alarm system have a smoke alarm response.

S14. According to the numerical relationship between the critical smoke concentration value and the standard alarm range, determine whether the smoke sensing function of the fire alarm system is in a normal working state.

In specific implementation, a camera can be mounted on the UAV to collect the environmental image information around the UAV and determine the smoke detector image information of the fire alarm system, which is convenient for controlling the flight status of the UAV, for example, the flight line, flight altitude etc.

It can be explained that the smoke alarm response of the fire alarm system to smoke refers to the alarm sent to the alarm controller or monitoring management server of the fire alarm system when the smoke generated by the electronic smoke generator is sensed by the smoke detector of the fire alarm system. information. Generally, smoke detectors have a standard alarm range. When the smoke concentration is within the standard alarm range, the smoke detector can sense the smoke and then send out an alarm message.

For example, the critical power value of the electronic cigarette generator is determined to be 3.5w, and according to the correspondence between the power of the electronic cigarette 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, while the value range of the standard alarm range is 0.1 to 0.15, then Make sure the smoke sensing function of the fire alarm system is not working properly.

If the critical smoke concentration value is within the standard alarm range, it is determined that the smoke sensing function of the fire alarm system is in a normal working state. The smoke sensing function of the fire alarm system is in normal working condition.

In the above technical solution, through the smoke alarm response of the fire alarm system to the smoke, the power of the smoke generated by the electronic smoke generator can be adjusted, and the critical power value of the electronic smoke generator can be determined to adapt to smoke detection with various sensitivities. Detector testing, and improve the accuracy of testing the fire alarm system's alarm response to smoke. Further, according to the corresponding relationship between the power of the electronic smog 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. Finally, according to the numerical relationship between the critical smoke concentration value and the standard alarm range, it is determined whether the smoke sensing function of the fire alarm system is in a normal working state. In this way, whether the smoke sensing function is in a normal state can be tested from the closed-loop level of the fire alarm system, thereby improving the accuracy and convenience of the test.

Fig. 2 is a schematic flowchart of another method for testing a smoke sensing function according to an exemplary embodiment. As shown in Figure 2, the method includes:

S21. Determine the initial power value of the electronic smoke generator according to the smoke detector information of the fire alarm system.

Wherein, the initial power value is used to make the electronic smoke generator on the UAV generate smoke according to the initial power value, and the smoke detector information includes the model of the smoke detector and the shape of the smoke detector.

S22. Control the electronic smoke generator on the drone to generate smoke according to the initial power value.

S23. Based on the smoke alarm response of the fire alarm system to the smoke, adjust the smoke generating power of the electronic smoke generator.

S24. Determine the critical power value of the electronic smoke generator, and determine the critical smoke concentration value corresponding to the critical power value according to the correspondence between the power of the electronic smoke generator and the smoke concentration, wherein the critical The power value refers to a critical power value that triggers a smoke alarm response of the fire alarm system.

S25. According to the numerical relationship between the critical smoke concentration value and the standard alarm range, determine whether the smoke sensing function of the fire alarm system is in a normal working state.

In actual implementation, the sensitivity of smoke detectors in different areas of the fire alarm system may be different, and the initial power of the electronic smoke generator can be determined according to the smoke detector information, such as the model of the smoke detector and/or the shape of the smoke detector In this way, the number of times to adjust the smoke generating power of the electronic smoke generator can be reduced. It is further convenient to test whether the smoke sensing function is in a normal state.

In a possible implementation, a database can be established according to the standard alarm range of the smoke detector of the fire alarm system, and the corresponding relationship between the model of the smoke detector and the initial power value can be established in the database, or the shape of the smoke detector and the initial power value can be established. Correspondence of the initial power value. In this way, the initial power value in the database can be matched according to the model or shape of the smoke adjuster, so as to conveniently determine the initial power value of the electronic smoke generator. Improve the convenience of testing whether the smoke detection function is in normal condition.

In another possible implementation, smoke detector information can be collected and an initial power value input by humans can be received, so as to control the electronic smoke generator on the UAV to generate smoke according to the initial power value.

Fig. 3 is a schematic flowchart of another method for testing a smoke sensing function according to an exemplary embodiment. As shown in Figure 3, the method also includes:

S31. Determine a CPK (Complex Process Capability Index, process capability index) value of the smoke detector according to the difference between the critical smoke concentration value and the central value of the standard alarm range.

The CPK value is an indicator of whether the reaction product is qualified. For a smoke detector, the closer the critical smoke concentration value that can trigger a smoke alarm to the center value of the standard alarm range specified by the industry, the higher the CPK value of the smoke detector. That is, the better the product performance. In addition, because the higher the CPK value, the higher the cost of the product, so in practical applications, it is usually to adjust the CPK value of the product within the acceptable reference value range.

S32. Determine the consistency of the smoke alarm response of the smoke detector according to the numerical relationship between the CPK value and a reference value range.

Specifically, after determining the critical smoke concentration value of the smoke detector to be tested, 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 the supplier, for example, If the CPK value of the smoke detector is determined to be 1.55, then according to the reference range 1.67≤CPK≤2.0, it is determined that the consistency of the smoke alarm response of the smoke detector does not meet the requirements, and it is necessary to replace the critical smoke concentration value and the central value of the standard alarm range Some smoke detectors with a large difference; if the CPK value of the smoke detector is determined to be 2.2, on the basis of considering safety and cost, smoke detectors with lower sensitivity can be considered.

Fig. 4 is a schematic flowchart of another method for testing a smoke sensing function according to an exemplary embodiment. As shown in Figure 4, the method also includes:

S41. Determine the first smoke alarm location information according to the location information of the smoke alarm response of the fire alarm system, and determine the second smoke alarm location information according to the location information of the drone.

S42. Determine whether the location information represented by the first smoke alarm location information is consistent with the location information represented by the second smoke alarm location 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 relationship between the car number and the smoke detector number is established. When the smoke detector of 001 has alarm information of smoke perception, it is determined that the smoke detector is set in the position near the front of the car in compartment 1 through the corresponding relationship between the number of the car and the number of the smoke detector.

Further, according to the position information of the drone, the position of the smoke detector tested at this time is determined. If the location information of the drone indicates that the smoke detector tested at this time is at the position near the rear of the compartment 1, then it is determined that the smoke perception of the fire alarm system is inconsistent, that is, the smoke detector of the fire alarm system is determined to be consistent with the management server. Wrong wiring connection.

In this way, 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, it can be determined that the smoke detector of the fire alarm system is incorrectly connected to the management server, and then change the connection in time to ensure Accuracy of smoke sensing function in fire alarm systems.

In step S12, based on the smoke alarm response of the fire alarm system to the smoke, the smoke generation power of the electronic smoke generator is adjusted, including:

If the fire alarm system does not receive the feedback information of the smoke alarm response to the smoke within the preset time, control the power of the electronic smoke generator to generate smoke to increase; or

If the fire alarm system receives the feedback information of the smoke alarm response to the smoke within the preset time, the power of the electronic smoke generator to generate smoke is controlled to decrease.

Specifically, when the electronic smog generator on the UAV is controlled to continue to generate smoke, within a preset period of time, no feedback information is received from the fire alarm system on the smoke alarm response to the smoke, indicating that the fire alarm system has a high sensitivity to the concentration. If there is no smoke alarm response to smoke, the power of the electronic smoke generator to generate smoke is controlled to increase. For example, if the electronic smog generator on the drone is controlled to continue to generate smoke, within 1 minute of the preset time, if no feedback information is received from the fire alarm system on the smoke alarm response to the smoke, the electronic smog generator is controlled The power of generating smoke is increased by 1w. Within 1 minute of the preset time, if the fire alarm system still does not receive the feedback information of the smoke alarm response to the smoke, the power of controlling the electronic smoke generator to generate smoke is increased by 1w again. and so on.

Correspondingly, the reduction of the power for controlling the generation of smoke by the electronic smoke generator is omitted here.

Optionally, the value of increasing or decreasing the power of the electronic smoke generator to generate smoke each time is controlled can be different, and the preset time can also be different according to the power.

In step S13, determine the critical power value of the electronic smoke generator, including:

The power value corresponding to receiving the feedback information between receiving the feedback information two times adjacently and not receiving the feedback information is used as the critical power value.

Specifically, if the feedback information of the fire alarm system’s smoke alarm response to the smoke is received in the previous time, and the feedback information of the fire alarm system’s smoke alarm response to the smoke is not received in the next time, the power value corresponding to the smoke generated in the previous time is the critical power value; if the feedback information of the fire alarm system’s smoke alarm response to the smoke was not received in the previous time, and the feedback information of the fire alarm system’s smoke alarm response to the smoke is received in the next time, then the corresponding The power value is the critical power value.

Optionally, the method also includes:

Controlling the UAV to adjust the position, so as to adjust the relative position relationship between the smoke outlet of the electronic smoke generator and the smoke detector of the fire alarm system.

For example, the image information of the smoke outlet of the electronic smoke generator and the smoke detector of the fire alarm system is collected through the camera, and when the position of the smoke outlet of the electronic smoke generator and the smoke detector are not suitable, the drone can be controlled Position adjustment, for example, when the height of the smoke outlet of the electronic smoke generator is far away from the smoke detector, control the height of the drone to rise appropriately.

Optionally, multiple cameras can be set on the UAV, for example, two cameras are set, one camera is used to collect the image information of the UAV flight, and the other camera is used to collect the smoke outlet of the electronic smoke generator and the fire Image information of the smoke detectors of the alarm system. In this way, operations to control camera rotation can be reduced. Avoiding the need to adjust the flight state of the drone while observing the relative positional relationship between the smoke outlet of the electronic smoke generator and the smoke detector of the fire alarm system, and repeatedly controlling the camera to rotate back and forth.
