In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to fig. 1 to 9 and the embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
Embodiments of the application are described in further detail below with reference to the drawings.
The embodiment of the application discloses a fire safety inspection method for an open space, which is characterized in that when a fire sensor is detected, a more reasonable path is planned according to the position of the fire sensor and the local wind direction condition for movement of an unmanned vehicle to be inspected, and the unmanned vehicle is inspected to release fire so as to obtain a feedback signal of the fire sensor, so that whether the fire sensor is effective or not can be effectively judged, and the overall inspection efficiency of the fire sensor is greatly improved.
Referring to fig. 1, a method flow of the fire safety inspection method of an open space includes the steps of:
step S100: the equipment placement location of the fire sensor requiring inspection is obtained.
The place where the apparatus is placed is the place where the fire sensor, i.e. the smoke sensor, to be checked is placed.
Step S101: and determining an equipment checking path on a preset open space map according to the placement places of the equipment.
The open space map is a map of an open space in which each fire sensor is arranged, and is marked with all road routes for the inspection vehicle to move, and even if the inspection vehicle sequentially inspects the fire sensors on each equipment placement site, the equipment inspection route can be determined by sequentially numbering the equipment placement sites and connecting the equipment placement sites from front to back according to the numbers, or by the method of step S200-step S206, which is not described herein.
Step S102: and controlling the preset inspection unmanned vehicle to move along the equipment inspection path and releasing the fire signal.
The fire signal is the smoke signal which can be sent out by the inspection unmanned vehicle, and the inspection unmanned vehicle is controlled to move along the equipment inspection path and release the fire signal, so that the simulation of the fire condition can be realized, and the specific reaction condition of each fire sensor can be known.
Step S103: and receiving a fire feedback signal on the fire sensor according to the fire signal when the unmanned vehicle arrives at the equipment placement site.
The fire feedback signal is a signal that the fire sensor outputs to the connected system after the fire signal enters the sensing range of the fire sensor, and the feedback signal includes a fire sensing signal and a fire non-sensing signal.
Step S104: and judging whether the fire feedback signal is consistent with a preset fire sensing signal.
The fire sensing signal is a fire feedback signal which is output when the fire sensor works normally when detecting fire, and the purpose of the judgment is to know whether the current fire sensor can work normally or not.
Step S1041: and if the fire feedback signal is consistent with the fire sensing signal, outputting a qualified signal of the equipment.
When the fire feedback signal is consistent with the fire sensing signal, the fire sensor can sense the fire normally, the equipment can work normally, and the qualified signal of the equipment is output at the moment to identify the fire sensor, so that the follow-up management is convenient.
Step S1042: if the fire feedback signal is inconsistent with the fire sensing signal, outputting a device damage signal.
When the fire feedback signal is inconsistent with the fire sensing signal, the fire sensor can not sense the fire normally, the equipment can not work normally, and the equipment damage signal is output at the moment to identify the fire sensor, so that the follow-up management is convenient.
Referring to fig. 2, the step of determining an equipment inspection path on a preset open space map according to each equipment placement location includes:
step S200: and acquiring regional wind direction information.
The regional wind direction information is the wind direction of external wind force owned by the current region where the open space is located in most of the time in the fire-fighting inspection time period, and the most of the time is the time with the largest wind direction time occupation ratio which can occur in the inspection time period, so that the regional wind direction information can be obtained by connecting with an external weather prediction network.
Step S201: and using a preset equipment starting point as a starting point, and arranging and combining the equipment placing places in sequence to determine different theoretical operation paths.
The equipment starting place is the position of the unmanned aerial vehicle in the empty space when the unmanned aerial vehicle is not operated, the theoretical operation path is the moving path of the unmanned aerial vehicle when the equipment placing place is checked in different orders, for example, the equipment starting place is O, the equipment placing place is A, B, and the obtained theoretical operation paths are OAB and OBA respectively.
Step S202: and determining a signal coverage distance according to the wind direction information of two adjacent places and areas and a preset signal transmission distance on the theoretical operation path.
The signal transmission distance, namely the distance value which can be influenced by the fire signal released at present, can be determined in advance by staff according to the condition of the intensity of the fire signal, and is a fixed value; the signal coverage distance is the nearest distance between the rear end of the adjacent sites and the area covered by the fire signal; the signal coverage distance can be determined by two adjacent places, the azimuth condition between the two places can be determined according to the azimuth condition and the regional wind direction information, the signal coverage distance can be determined according to the deviation angle and the signal transmission distance by a database established in advance, and meanwhile, the signal coverage distance can also be determined by the method from step S300 to step S304, and the description is omitted here.
Step S203: and defining a virtual point with the signal coverage distance smaller than the preset equipment induction distance as a qualified point, and determining an advance distance according to the qualified point and a place at the rear end in the adjacent places.
The equipment sensing distance is the range of fire signals which can be sensed under the normal condition of the equipment, when the signal coverage distance is smaller than the equipment sensing distance, the condition of the fire sensor is checked in advance due to the fact that the possibility of the unmanned vehicle moving to the virtual point is high, the fire sensor is defined as a qualified point at the moment so as to realize the identification of different virtual points, and the follow-up step analysis is facilitated; the advance path is the minimum path that the unmanned vehicle needs to move when moving from the pass point to the place at the fire sensor at the rear end in the adjacent fire sensors.
Step S204: the advanced distance with the largest value is determined according to a preset sorting rule, and the advanced distance is defined as the shortened distance between two adjacent places.
The sorting rule is a method which is set by staff and can sort the values, such as an bubbling method, and the advanced distance with the largest value can be determined through the sorting rule, namely, the distance which can be reduced by the qualified point corresponding to the advanced distance is the largest, and the shortened distance is defined at the moment to be used for marking, so that the subsequent analysis is convenient.
Step S205: and determining a theoretical working distance according to the theoretical working distance, and calculating according to the theoretical working distance and all the shortening distances to determine the comprehensive moving distance.
The theoretical operation route is the total route required to be moved when the inspection unmanned vehicle moves along the theoretical operation route, the comprehensive movement route is the route required to be moved when the inspection unmanned vehicle is loved to check all fire sensors in the theoretical situation, and the sum of all shortened routes is subtracted from the theoretical operation route to determine.
Step S206: and determining the comprehensive moving path with the minimum value according to the sorting rule, and determining the theoretical operation path corresponding to the comprehensive moving path as the equipment checking path.
The comprehensive moving path with the minimum value can be determined through the sorting rule, namely, the path required to move for checking the unmanned vehicle is minimum under the theoretical operating path, and the corresponding theoretical operating path is determined to be the equipment checking path at the moment, so that the overall operating efficiency of checking the unmanned vehicle is improved.
Referring to fig. 3, the step of determining the signal coverage distance according to the wind direction information of two adjacent sites, the regional wind direction information and the preset signal transmission distance on the theoretical work path includes:
Step S300: a path between two adjacent points on the theoretical work path is defined as an analysis path, and a point at the rear end in the analysis path is defined as a target point.
And defining analysis paths and target points to realize the distinction of different paths and places, so that the analysis of subsequent steps is facilitated.
Step S301: a randomly changeable virtual point is established on the analysis path.
The virtual point is a point whose position on the analysis path can be changed randomly.
Step S302: and determining a signal response line segment according to the regional wind direction information and a preset signal transmission distance, and establishing a detection point with a randomly changeable position on the signal response line segment.
A signal response line segment, namely a range coverage line segment which can be affected by fire signals, refers to fig. 4, namely a line segment obtained by extending a signal transmission distance in a direction corresponding to regional wind direction information with a virtual point as a starting point; the detection point is a point where a position on the signal response line segment can be randomly changed.
Step S303: and determining the point separation distance according to the target point and the detection point.
The point separation distance is the value of the straight line distance between the target point and the detection point.
Step S304: and determining the point separation distance with the minimum value according to the ordering rule, and determining the point separation distance as the signal coverage distance.
The distance between the points with the smallest value can be determined through the ordering rule, namely the detection point is the point where the fire sensor at the target point is most likely to detect the fire, and the distance between the corresponding points is determined to be the signal coverage distance.
Referring to fig. 5, the step of creating a randomly changeable virtual point on the analysis path includes:
Step S400: the target point is used as a circle center, a preset fixed distance is used as a radius to define a fixed area, and a path part in the fixed area in the analysis path is defined as a reasonable path.
The fixed distance is a fixed value distance set by a worker, and the fixed area is an area defined by taking the target point as a circle center and the radius as the fixed distance; reasonable paths are defined to distinguish between different path segments on an analysis path, facilitating subsequent analysis.
Step S401: virtual points are established on the reasonable path from front to back according to the theoretical operation path, and after the qualified points are determined, the advance distance is determined according to the qualified points.
Virtual points are built only from front to back on a reasonable path, so that judgment and detection are preferentially carried out on the virtual points meeting requirements; after the qualified point is determined, the subsequent virtual point on the reasonable path cannot be better than the current qualified point, and the advance path is determined directly.
Step S402: and determining an analysis operation route according to the analysis route, and determining an advance duty ratio according to the advance route and the analysis operation route.
The analysis operation route is the whole route length of the analysis route, and the advance ratio is the advance route divided by the numerical value ratio obtained by the analysis operation route.
Step S403: and judging whether the advanced duty ratio is larger than a preset meeting duty ratio.
The minimum advance duty ratio when the duty ratio is the determined route set by the staff and the advance is more is satisfied, and the purpose of judgment is to know whether virtual point establishment judgment is needed for other points.
Step S4031: and if the advanced duty ratio is larger than the satisfied duty ratio, stopping establishing the virtual point.
When the advanced duty ratio is larger than the satisfied duty ratio, the fact that a proper virtual point is found is indicated, and the establishment of the virtual point is stopped at the moment, so that the amount of the virtual point to be established is reduced, and the overall operation efficiency is improved.
Step S4032: and if the advanced duty ratio is not greater than the satisfied duty ratio, correcting the fixed distance according to the preset correction distance, and updating the fixed area according to the new fixed distance until the establishment of the virtual point is stopped.
When the advance duty cycle is not greater than the satisfactory duty cycle, it is stated that there may be more suitable fit points that require further analysis; the correction distance is a preset fixed distance of a worker, and the fixed distance can be updated by adding the original fixed distance to the correction distance, so that a fixed area with a larger range can be defined, and a proper qualified point can be conveniently determined.
Referring to fig. 6, the fire safety inspection method of an open space further includes:
step S500: and moving the unmanned inspection vehicle along the equipment inspection path to acquire self-induction signals of the fire sensor of the target point.
The self-induction signal is the fire induction signal output by the fire sensor when the unmanned vehicle is checked to be not moved to the target point, and is consistent with the fire feedback signal.
Step S501: and acquiring the current position of the equipment and the external wind direction information when the self-induction signal is consistent with the fire disaster induction signal.
When the self-induction signal is consistent with the fire induction signal, the signal of the fire is successfully detected, and at the moment, the condition of false detection possibly exists, and further analysis is needed; the current position of the equipment is the current position of the unmanned vehicle, and the external wind direction information is the direction of external wind under the current time point.
Step S502: and determining the induction short-range distance according to the current position of the equipment, the target point and the external wind direction information.
The sensing short distance is the nearest distance between the point of the fire signal for the target point or the sensor to sense and the target point, and the determining method is consistent with the signal coverage distance and will not be described herein.
Step S503: and judging whether the sensing short distance is smaller than the sensing distance of the device.
The purpose of the judgment is to know whether the fire signal sensed by the fire sensor is brought by the inspection unmanned vehicle.
Step S5031: and if the sensing short distance is not smaller than the sensing distance of the equipment, outputting an equipment abnormal signal.
When the induction short distance is not smaller than the equipment induction distance, the condition that the fire sensor is abnormal at the moment and the current position of the unmanned vehicle and external environment factors cannot meet the fire induction requirement are explained, and equipment abnormal signals are output at the moment to identify the condition so as to facilitate targeted processing of subsequent staff.
Step S5032: and if the induction short distance is smaller than the equipment induction distance, outputting an equipment qualification signal.
When the induction short distance is smaller than the equipment induction distance, the fact that the current position of the unmanned vehicle and external environment factors can meet fire induction requirements is indicated, at the moment, the fire sensor works normally, and at the moment, equipment qualification signals are output to identify the situation.
Step S504: and after the equipment abnormal signal or the equipment qualified signal is output, updating an equipment inspection path according to the current position of the equipment and the equipment placement place of the residual non-inspected fire sensor, and controlling the inspection unmanned vehicle to move along the updated equipment inspection path.
When the equipment abnormal signal or the equipment qualified signal is output, the fire sensor at the target point is indicated to be inspected, and the equipment inspection path is updated at the moment so that the subsequent inspection unmanned vehicle can work quickly, thereby improving the overall efficiency, wherein the updating method of the equipment inspection path and the current position of the equipment are taken as the equipment starting position, and the equipment inspection path is determined again according to the rest undetected equipment placement places.
Referring to fig. 7, if the fire feedback signal is identical to the fire sensing signal, the fire safety inspection method for an open space further includes:
step S600: and acquiring the signal feedback intensity of the fire feedback signal.
The signal feedback intensity, i.e. the signal intensity of the received fire feedback signal, is the stronger the signal intensity is, the stronger the detected fire signal is.
Step S601: and judging whether the signal feedback intensity is smaller than the preset signal demand intensity.
The signal demand intensity is the minimum signal feedback intensity that the staff set to the best acceptance needs to satisfy when checking the fire signal on the unmanned aerial vehicle at present, and the purpose of judgement is in order to learn whether current fire sensor exists the condition that detects the response weak.
Step S6011: and if the signal feedback intensity is not less than the signal demand intensity, outputting a qualified signal of the equipment.
When the signal feedback intensity is not less than the signal demand intensity, the condition that the fire sensor does not have weak induction is indicated, namely, all equipment is normal, and at the moment, an equipment qualified signal is output to identify the fire sensor.
Step S6012: if the signal feedback intensity is smaller than the signal demand intensity, the weak induction signal of the equipment is output.
When the signal feedback intensity is smaller than the signal demand intensity, the condition that the sensing of the fire sensor is weak is described, and at the moment, the weak sensing signal of the equipment is output so as to mark the fire sensor, so that the follow-up staff can process in a targeted manner.
Referring to fig. 8, if the fire feedback signal is inconsistent with the fire sensing signal, the fire safety inspection method for open space further includes:
step S700: the fire control signal is continuously enhanced and the fire release intensity is obtained in real time.
When the fire feedback signal is inconsistent with the fire sensing signal, the condition that the current fire sensor senses weak and cannot effectively sense the fire signal possibly exists, and further analysis is needed; the fire signal is continuously enhanced so that the fire sensor can better detect the fire, and the fire release intensity is the intensity of the fire signal released outwards.
Step S701: and judging whether the fire feedback signal is consistent with the fire induction signal in the fire signal strengthening process.
The purpose of the judgment is to know that the current equipment has weak equipment induction.
Step S7011: and if the fire feedback signal is consistent with the fire sensing signal, outputting a weak sensing signal of the equipment.
When the fire feedback signal is consistent with the fire induction signal, the condition that the fire feedback signal is inconsistent with the fire induction signal before the explanation is caused by weak equipment induction, and the weak equipment induction signal is output at the moment to identify the condition, so that the follow-up staff can process in a targeted manner conveniently.
Step S7012: if the fire feedback signal is inconsistent with the fire sensing signal, continuing to strengthen the fire signal until the fire release intensity is greater than the preset limit intensity, and outputting a device damage signal.
When the fire disaster feedback signal is inconsistent with the fire disaster induction signal, the fire disaster signal still cannot be induced, the maximum fire disaster release intensity when the fire disaster signal can be induced by equipment with weak identification induction capacity and set by staff is also obtained, when the fire disaster release intensity is larger than the limit intensity, the fire disaster sensor is still not induced, the damage is indicated, and the equipment damage signal is output at the moment so as to mark the equipment, so that the follow-up treatment is facilitated.
