Description

Technical Field

[0001] This invention relates to the field of fire safety technology, and in particular to a safe emergency escape method and related devices for prefabricated substations. Background Technology

[0002] With the advancement of urbanization and the rapid growth of social electricity demand, conventional substations face prominent problems such as large land area, long construction period, low construction efficiency, and high capital investment costs, which constantly restrict the high-quality development of the power grid. Under the major strategic deployments of the national new power system and green carbon peaking, prefabricated substation modules have emerged. Prefabricated modules have advantages such as good dustproof, moisture-proof, shockproof, thermal insulation, flame retardant and impact-resistant properties, which greatly improve the operation and maintenance efficiency of substations.

[0003] However, due to the structural layout of the prefabricated cabin, the various functional rooms inside the cabin form a closed space. In the event of an emergency such as gas leakage, equipment short circuit, or explosion, smoke will quickly fill the entire prefabricated cabin and the smoke concentration will increase rapidly, making the visibility inside the prefabricated cabin extremely low. The existing safety escape instructions are only illuminated signs or low-brightness bulbs at the safety exits, which are difficult to provide escape guidance to the staff in the cabin with high smoke concentration. Summary of the Invention

[0036] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0037] This invention provides a safe emergency escape method for prefabricated substations, which solves the problems of low efficiency and low reliability of manual verification of electrical measuring instruments in the prior art.

[0038] Please see Figure 1 , Figure 1 This is the first flowchart of a safety emergency escape method for a prefabricated substation provided in an embodiment of the present invention.

[0039] S100: When an emergency escape signal is received, the first location of personnel in the station is obtained.

[0040] It should be noted that the emergency escape signal is issued by the prefabricated substation after an accident is detected by a temperature sensor or smoke alarm, or by the substation management personnel or staff who discover the incident. In this embodiment, the emergency escape signal is received by the controller of the escape indicator light in the prefabricated substation.

[0041] Upon receiving an emergency escape signal, the indicator light controller determines that personnel inside the prefabricated substation require a safety emergency escape instruction. At this time, the first location of the personnel inside the station can be obtained through a distance sensor installed in the passageway; the distance sensor can be an infrared transmitter or a thermal imager.

[0042] S200, determine the emergency exit based on the first location of the personnel in the station, and turn on the indicator light corresponding to the emergency exit;

[0043] It should be noted that the prefabricated substation has multiple emergency exits. Based on the first location of the personnel inside the station, the nearest emergency exit to the personnel at the moment the emergency escape signal is received is determined. In this embodiment, escape indicator lights are set on the emergency exits, and each emergency exit has a corresponding escape indicator light. The indicator light on the emergency exit closest to the personnel inside the station is controlled to improve escape efficiency. The indicator light controller can act as a control terminal to control the operation of multiple escape indicator lights at the same time, or a controller can be set for each indicator light. After the indicator light corresponding to the emergency exit that is set to be activated is activated, the controller of that indicator light communicates with the distance sensor for further control.

[0044] S300: Real-time acquisition of the second position of personnel within the station; Calculation of the illumination angle of the indicator light based on the second position of the personnel within the station using a preset angle algorithm; Conversion of the illumination angle into a rotation signal and sending it to the stepper motor of the indicator light.

[0045] It should be noted that the location of personnel inside the station changes in real time during emergency evacuation, and the second location will also change accordingly; the escape indicator light is installed on the emergency exit, and the illumination trajectory shines obliquely onto the passage of the prefabricated substation. The illumination angle of the indicator light is changed according to the second location so that the light of the escape indicator light shines on the feet of the personnel inside the station or between the escape indicator light and the emergency exit.

[0046] The escape indicator lights are high-penetration spotlights, ensuring illumination even in dense smoke environments. The indicator light controller is pre-set with the installation height and coordinates of each indicator light. The difference between the second position and the indicator light coordinates gives the horizontal distance to the personnel inside the station. The horizontal distance, installation height, and projection line of the indicator light form a right triangle. According to the sine theorem, the required illumination angle between the indicator light and the vertical direction when it shines on the second position can be obtained. This illumination angle is converted into an electrical pulse signal corresponding to the angular displacement of the indicator light's stepper motor, thus forming a rotation signal. The controller sends this rotation signal to the stepper motor of the indicator light, causing the indicator light to follow the personnel inside the station in real time.

[0047] Compared to other building facilities, prefabricated substations have a more enclosed internal space, making it difficult to have external light sources for auxiliary lighting. Furthermore, due to the small number of staff and the simple structure of the workspace, this embodiment is conducive to personnel positioning and lighting tracking guidance. Compared to fire safety indicator lights in public places, it can provide more efficient and accurate escape instructions.

[0048] In this embodiment, in an emergency escape situation, the nearest emergency exit and corresponding indicator light are activated based on the first position of the personnel in the station, and the illumination angle of the indicator light is adjusted based on the real-time second position of the personnel in the station. This allows the indicator light to accurately illuminate the feet of the personnel in the station in dark and high smoke concentration conditions, efficiently and accurately guiding the staff in the station to escape in an emergency.

[0049] In case of emergency, the indicator lights can accurately guide personnel in the prefabricated cabin to the escape route. Following the light path will lead to the emergency exit. Compared with the existing emergency exit indicator lights or diffused light bulbs, the indicator effect is better.

[0050] The above is a detailed description of the first embodiment of a safety emergency escape method for a prefabricated substation provided in this application. The following is a detailed description of the second embodiment of a safety emergency escape method for a prefabricated substation provided in this application.

[0051] This embodiment further provides a safe emergency escape method for prefabricated substations. Please refer to [link to relevant documentation]. Figure 2 Step S200 specifically includes steps S201-S203, as detailed below:

[0052] S201, determine the emergency exit based on the first position of the personnel in the station, and turn on the indicator light corresponding to the emergency exit; detect the current smoke concentration in real time through the smoke sensor, and determine whether the current smoke concentration exceeds the preset threshold. If not, set the indicator light to the minimum power and set the illumination angle to vertically downward; if so, proceed to step S202.

[0053] It should be noted that the 10kV switchgear and 110kV GIS high-voltage equipment corresponding to the prefabricated cabin layout in this embodiment typically contain SF6 gas, aviation fuel, and insulating varnish, plastic, and insulation sheath of the corresponding control cables. When high-voltage equipment of different voltage levels in operation suddenly experiences a short circuit or explosion, the huge short-circuit current will generate a high-temperature effect, causing fires to break out in the equipment itself and its surrounding accessories, buildings, surrounding air conditioners, and the equipment's own plastics. The combustibles mainly include sulfides, hydrides, sulfur dioxide, carbon dioxide, various dusts, SO2, NOx, CO, CO2, and small amounts of fluorides and chlorides.

[0054] When the smoke concentration does not exceed the preset threshold, it indicates that the current smoke concentration is low. Although the prefabricated cabin is completely dark in the event of a power outage, the diffuse reflection light of the indicator lights is clearly visible. There is no need to directly shine the light on personnel for tracking. Moreover, the indicator lights only need to operate at minimum power to provide escape directions for personnel in the station, or the regular indicator lights can be turned on directly.

[0055] In this embodiment, an infrared smoke sensor is used. The infrared beam of the infrared emitting tube is scattered by smoke particles. The intensity of the scattered light is proportional to the concentration of smoke, which causes the intensity of the infrared beam received by the photosensitive tube to change. The intensity of the scattered light is also directly related to the visibility of smoke. Referring to the existing standard that the light intensity of evacuation lighting is not less than 5LX, it is used as the reference standard for setting the preset threshold. Combined with the types of smoke that will be generated in the actual prefabricated cabin, the smoke concentration corresponding to the minimum power of the indicator light scattered light is equal to 5LX is used as the preset threshold.

[0056] Furthermore, after determining that the current smoke concentration does not exceed the preset threshold and turning on the indicator light with minimum power, the smoke concentration may further increase as the high-voltage equipment malfunctions. Therefore, the determination of whether the smoke concentration exceeds the preset threshold continues.

[0057] S202 adjusts the indicator light power in real time according to the current smoke concentration.

[0058] It should be noted that, as the smoke concentration may increase rapidly, in order for the indicator lights to penetrate the dense smoke and provide guidance to personnel inside the station, the power of the indicator lights needs to be increased to ensure the penetration of the spotlights. Based on the evacuation lighting intensity standard and the preset smoke concentration and refraction relationship, the power of the indicator lights should be adjusted accordingly to ensure that the light intensity of the indicator lights when penetrating the dense smoke and illuminating the feet of personnel inside the station is not less than the evacuation lighting illuminance standard.

[0059] Furthermore, in the aforementioned step S100, when an emergency escape signal is received, if the distance detected by the distance sensor is the length of the prefabricated cabin passage, or the first position is the position of the prefabricated cabin wall, that is, no first position of the personnel currently in the station is detected, then the information that there are no personnel in the prefabricated cabin substation is fed back to the host computer; if no personnel are detected in the prefabricated cabin by the distance sensor, infrared sensor, laser rangefinder or thermal imager, there is no need to guide emergency escape.

[0060] Furthermore, in the aforementioned step S300, after determining the illumination angle, the method further includes: calculating the projection distance of the indicator light based on the illumination angle and the height of the indicator light, and adjusting the focal length of the focusing lens at the indicator light opening based on the projection distance; the focusing lens at the indicator light opening can enable the indicator light to project a specific indicator arrow pattern, further providing escape instructions to personnel inside the station.

[0061] Furthermore, in this embodiment, after identifying the emergency exit and its corresponding indicator light, a voice prompt can be issued to remind personnel in the station that an emergency has occurred and to evacuate to the emergency exit in the direction of the indicator light as soon as possible.

[0062] In this embodiment, a smoke sensor detects the smoke concentration and adjusts the luminous power of the indicator light in real time to ensure the penetrability of the indicator light and improve the reliability of emergency escape guidance.
