Description

Technical Field

[0001] The present invention relates to the technical field of fire detection systems, and in particular to a fire detection system and a detection method. Background Art

[0002] Fire safety is the top priority of safety protection in modern construction, especially in some indoor, storage buildings, factories and other closed buildings. Fire detection systems are necessary and need real-time monitoring to reduce the loss of life and property caused by fire.

[0003] In the prior art, most fire detection systems do not have a delay function. When a short alarm signal appears in the indoor personnel and working environment, the detection system will make a wrong judgment, causing the equipment in the detection system to malfunction frequently. Summary of the invention

[0004] In view of the deficiencies in the prior art, an object of the present invention is to provide a fire detection system and a detection method to solve the above problems.

[0005] In view of this, the present invention provides a fire detection system, comprising: A controller is installed on the wall, the controller comprises a housing, a delay module arranged in the housing, a time module, a control structure and a button arranged on the housing of the controller, the delay module is respectively connected with the time module and the control structure by wires; Fire detection device, installed at the top of the room; A fire detection camera is installed at the center of the top of the room, and the fire detection camera is electrically connected to the control module; and an alarm device, which is arranged indoors and electrically connected to the fire detection camera; Wherein, the button is used to set the time module and the delay module, and the fire detection device is electrically connected to the delay module and the control structure.

[0006] By adopting the above technical scheme, the time module and the delay module can be set through the setting of buttons. Through the setting of the time module, the working status and working time of the delay module can be set. Through the setting of the delay module, it can be determined how many seconds the fire detection device continues to alarm before the control structure receives the alarm signal. Through the setting of the fire detection device, fire signal detection can be carried out. Through the setting of the alarm device, the operator can be reminded. Through the setting of the fire detection camera, fire can be detected. Through the setting of the control structure, the fire detection camera can be controlled to realize detection of specific positions. When the fire detection device reaches the fire signal value, the fire detection device sends a signal to the delay module. The delay module determines whether it is in the time period set by the time module. If it is in the time period, the delay module determines whether it is in the time period set by the time module. When the time period is set by the time module, the delay module continues to receive the fire signal from the fire detection component until the continuous sending time of the signal from the fire detection component exceeds the time length set by the delay module, and the delay module sends a fire alarm signal to the control module. When the continuous sending time of the signal from the fire detection component does not exceed the time length set by the time module, the delay module restarts the timing and does not send an alarm signal to the control module. When the fire signal is not in the time period set by the time module, the delay module directly sends an alarm signal to the control module when it receives the fire signal. Due to the close activities of people during the day, when people smoke and produce short-term smoke, the fire detection device will have a short-term alarm phenomenon, which will cause a fire alarm signal. Through the effect of the delay module, false alarm signals caused by indoor personnel and working environment during the day can be avoided.

[0007] In the above technical solution, the fire detection device further includes a plurality of fire detection components, and the plurality of fire detection components are respectively arranged at intervals along the length direction of the indoor top, and the fire detection components each include a plurality of fire detection elements arranged in rows at intervals in the width direction of the indoor top, the fire detection elements on the spaced-apart fire detection components are arranged opposite to each other, and the fire detection elements on the adjacent fire detection components are staggered, and the plurality of fire detection elements are electrically connected to the delay module.

[0008] In the technical solution, by setting up a plurality of fire detection components, it is possible to detect a larger room and evenly detect all places in the room.

[0009] In the above technical solution, the control structure further includes: A judgment module is disposed in the housing and is electrically connected to a plurality of fire detection components; A control module is disposed in the housing and is electrically connected to the judgment module; Wherein, the control module is also electrically connected to the fire detection camera.

[0010] In this technical solution, through the setting of the judgment module, the approximate location of the fire can be preliminarily determined, and then sent to the control module according to the set signal. The fire detection camera is controlled to perform a specific detection path according to the input signal, thereby achieving rapid and accurate detection and rapid discovery of the fire location.

[0011] In the above technical solution, the alarm device further comprises: An audible and visual alarm is installed indoors and is electrically connected to a fire detection camera; A communication module is installed in the controller and is electrically connected to the fire detection camera; Wherein, the communication module is connected to the remote monitoring terminal via wireless communication.

[0012] In the technical solution, by setting up the sound and light alarm, a signal can be provided to the operator, by setting up the communication module, a picture can be sent to the operator, and a fire call can also be made to the operator.

[0013] In the above technical solution, the following steps are further included: S1: First, the operator sets the center position of each fire detection element as the preset point of the fire detection camera; S2: The operator sets the time module through buttons, and the time module controls the delay module; S3: The operator sets the delay module through buttons; S3: When the fire detection component detects a fire signal, the fire detection component sends the signal to the delay module, and the delay module determines whether it is in the time period set by the time module. When it is in the time period set by the time module, the delay module continues to receive the signal from the fire detection component until the continuous sending time of the signal from the fire detection component exceeds the time length set by the delay module, and the delay module sends an alarm signal to the control module. When the continuous sending time of the signal from the fire detection component does not exceed the time length set by the time module, the delay module will not send an alarm signal to the control module. When the fire signal is not in the time period set by the time module, the delay module directly sends an alarm signal to the control module when receiving the fire signal. S4: When the control module receives the alarm signal, the control module controls the judgment module to receive the signal values ​​of all fire detection components, the judgment module compares and judges the signal values ​​of several fire detection components, and then sends the judgment information to the control module, and the control module controls the fire detection camera to detect fire in a specific area according to the judgment information; S5: When the fire detection camera detects a fire, it sends a signal to the alarm device. When the fire detection camera completes the detection and finds no fire, the fire detection camera sends a signal to the control module, and the control module controls the delay module to re-timing for the next round of work; S6: When the alarm device receives the alarm signal from the fire detection camera, the alarm device sounds an alarm.

[0014] In this technical solution, through the setting of S1, the fire detection camera can be quickly moved to a specific location. Through the setting of S2, the working time of the delay module can be set through the time module, so that the operator can control the time period of false alarms and avoid false alarms in special time periods. Through the setting of S3, it is possible to control how long the fire detection component continues to reach the alarm signal before it is transmitted to the control module, so as to better achieve accurate time alarm. Through the setting of S4, a preliminary judgment of the fire location can be made, and the control module can better control the fire detection camera detection, so as to quickly and accurately find the fire, greatly reducing the fire detection time, and enabling the fire detection camera to be better detected in larger venues. Through the settings of S5 and S6, the operator can get the fire alarm signal.

[0015] In the above technical solution, the further S4 also includes: S401: When the judgment module receives the signal values ​​of the three fire detection components with the highest numerical signals and they are arranged in order of size, the judgment module sends the control module an A signal, and the control module controls the fire detection camera to run in the set path 1; S402: When the judgment module receives the values ​​of the three fire detection components with the highest numerical signals, and two signal values ​​are equal, and the fire detection component with the two equal signal values ​​is greater than the signal value of another fire detection component, the judgment module sends a B signal to the control module, and the control module controls the fire detection camera to run in the set No. 2 path; S403: When the judgment module receives the values ​​of the three fire detection components with the highest numerical signals, and two signal values ​​are equal, and the two equal signal values ​​are smaller than the signal value of another fire detection component, the judgment module sends a C signal to the control module, and the control module controls the fire detection camera to run along the set path No. 3, wherein the detection path of path No. 3 runs opposite to the detection path of S402, and the control module controls the detection lens of the fire detection camera to run opposite to the detection path of S402; S404: When no fire is detected in S401, S402 and S403, the control module controls the fire detection camera to detect the area between the straight line formed by the two fire detection elements with the highest signal values ​​and the wall; S405: When the signal values ​​of the three fire detection components with the highest signal values ​​received by the judgment module are close to or equal, the judgment module sends a D signal to the control module, and the control module controls the fire detection camera to run in the set No. 4 path; S406: When the judgment module receives the fire detection component numerical signal, there are four fire detection components with the highest signal values ​​and the detection values ​​of two fire detection components are equal, then the judgment module sends an F signal to the control module, and the control module controls the fire detection camera to run along the set path No. 5.

[0016] In the present technical solution, through the setting of S401, when the judgment module receives the signal values ​​of the three fire detection components with the highest numerical signals and they are sorted in order of size, the judgment module sends a specific signal to the control module, so that the control module controls the fire detection camera to run according to a preset path, so as to achieve the best path in this case. Through the setting of S402, when the judgment module receives the values ​​of the three fire detection components with the highest numerical signals and the signal values ​​of two fire detection components are equal and greater than that of the other fire detection component, the judgment module sends a specific signal to the control module, so that the control module controls the fire detection camera to run according to a preset path, so as to achieve the best path in this case. Through the setting of S403, when the judgment module receives the values ​​of the three fire detection components with the highest numerical signals and the signal values ​​of two fire detection components are equal and less than that of the other fire detection component, the judgment module sends a specific signal to the control module, so that the control module controls the fire detection camera to run according to a preset path. The fire detection camera can be operated along the path set in advance, thereby achieving the best path in this case. Through the setting of S404, it is possible to prevent the fire from occurring in the triangular area formed by the three fire detection components with the highest signal values, but between the two fire detection components with the highest signal values ​​and the wall. Through the setting of S405, when the signal values ​​of the three fire detection components with the highest signal values ​​are close to or equal, the judgment module sends a specific signal to the control module, so that the control module controls the fire detection camera to operate along the path set in advance, thereby achieving the best path in this case. Through the setting of S406, when the detection values ​​of the four fire detection components with the highest signal values ​​are equal to each other, the judgment module sends a specific signal to the control module, so that the control module controls the fire detection camera to operate along the path set in advance, thereby achieving the best path in this case. Through the path settings of S401, S402, S403, S404, S405 and S406, as long as the indoor fire detection camera can run the best path to find the fire source.

[0017] In the above technical solution, further, path No. 1 in S401 is: first, the control module controls the fire detection camera to rotate to the preset point of the fire detection element with the highest signal value for detection, and then the lens of the fire detection camera rotates toward the preset point of the second highest signal value, and fire detection is performed during the rotation process, at this time, the first detection path is completed, when the fire detection camera rotates to the preset point of the second highest signal value and no fire signal is detected, at this time, the control module controls the fire detection camera to rotate toward the fire detection element with the third highest signal value within a lens detection range, and then the lens of the fire detection camera rotates toward the preset point of the highest signal value and the rotation path of the fire detection camera is parallel to the first detection path, when the fire detection camera rotates to the preset point of the highest signal value and stops within a detection lens range, at this time, the second detection path is completed, when the second detection path does not detect a fire, the control module controls the fire detection camera to perform the third detection path, the fourth detection path, the fifth detection path and so on detection in the same way as the second detection path, until the detection of the triangular area formed by the three fire detection elements is completed; In the present technical solution, through the path setting of the above-mentioned fire detection camera, when the judgment module receives the signal values ​​of the three fire detection components with the highest numerical signals, which are arranged in order of size, the judgment module can first send a specific signal to the control module, and then the control module controls the fire detection camera to run along a pre-set path according to the specific signal, so as to achieve the best path in the situation, thereby achieving the fastest detection of the fire location and greatly increasing the accuracy.

[0018] In the above technical solution, the path No. 2 in S402 is further as follows: first, the control module controls the fire detection camera to rotate to a preset point of one of the fire detection components with equal signal values, and then the control module controls the detection lens of the fire detection camera to rotate toward the preset point of another fire detection component with equal signal value, and performs fire detection during the rotation process, at which time the first detection path is completed; when the first detection path does not detect a fire, the control module controls the fire detection camera to rotate toward the fire detection component with the third highest signal value by one lens detection range, and then the control module controls the lens of the fire detection camera to rotate toward a farther fire detection component with equal signal value and the rotation path of the fire detection camera is parallel to the first detection path; when the detection lens of the fire detection camera rotates to another fire detection component with equal signal value and stops within the range of one detection lens, the second detection path detection is completed; when the second detection path does not detect a fire, the control module controls the fire detection camera to perform the third detection path, the fourth detection path, the fifth detection path and so on detection in the same way as the second detection path until the detection of the triangular area formed by the three fire detection components is completed.

[0019] In the present technical solution, through the path setting of the above-mentioned fire detection camera, when the judgment module receives the numerical values ​​of the three fire detection components with the highest numerical signals, and the two signal values ​​are equal, and the fire detection component with the two equal signal values ​​is greater than the signal value of another fire detection component, the judgment module can first send a specific signal to the control module, and then the control module controls the fire detection camera to run along the pre-set path according to the specific signal, so as to achieve the best path in this case, thereby achieving the fastest detection of the fire location, greatly increasing the accuracy.

[0020] In the above technical solution, the path No. 4 in S402 is further as follows: the control module controls the detection lens of the fire detection camera to move to the center of gravity position of the triangular area formed by the three fire detection parts for fire detection. When no fire is detected at the center of gravity position, the control module controls the lens of the fire detection camera to perform spiral rotation detection at the center of gravity position until the detection of the triangular area is completed.

[0021] In the present technical solution, through the path setting of the above-mentioned fire detection camera, when the judgment module receives signal values ​​of the three fire detection components with the highest signal values ​​that are close to or equal, the judgment module can first send a specific signal to the control module, and then the control module controls the fire detection camera to run along a pre-set path according to the specific signal, so as to achieve the best path in this case, thereby achieving the fastest detection of the fire location and greatly increasing the accuracy.

[0022] In the above technical solution, the path No. 5 in S402 is further as follows: at this time, the preset points of the four fire detection components form a parallelogram area, and the control module controls the detection lens of the fire detection camera to move to the intersection of the diagonals of the parallelogram area for fire detection. When no fire is detected, the control module controls the lens of the fire detection camera to perform spiral rotation detection until the parallelogram area is detected.

The above-mentioned fire detection camera 4 determines the position where the fire location is close to based on the signal value of the fire detection component 6, so the running path is also the fastest and the first to find the fire location.

[0039] Embodiment 8: In this embodiment, in addition to the structural features of the aforementioned embodiments, the path No. 2 in S402 is further as follows: first, the control module 8 controls the fire detection camera 4 to rotate to a preset point of one of the fire detection components 6 with equal signal values, and then the control module 8 controls the detection lens of the fire detection camera 4 to rotate toward another preset point of the fire detection component 6 with equal signal value, and performs fire detection during the rotation process. At this time, the first detection path is completed. When the first detection path does not detect a fire, the control module 8 controls the fire detection camera 4 to rotate toward the fire detection component 6 with the third highest signal value by a lens detection range. Then the control module 8 controls the lens of the fire detection camera 4 to rotate toward the fire detection element 6 with equal signal value that is farther away, and the rotation path of the fire detection camera is parallel to the first detection path. When the detection lens of the fire detection camera 4 rotates to the range of one detection lens of another fire detection element 6 with equal signal value and stops, the detection of the second detection path is completed at this time. When the second detection path does not detect a fire, the control module 8 controls the fire detection camera 4 to perform the third detection path, the fourth detection path, the fifth detection path and so on detection in the same way as the second detection path, until the detection of the triangular area formed by the three fire detection elements 6 is completed; Through the path setting of the fire detection camera 4, when the judgment module 7 receives the values ​​of the three fire detection components 6 with the highest numerical signals, and the two signal values ​​are equal, and the fire detection components 6 with the two equal signal values ​​are greater than the signal value of another fire detection component 6, the judgment module 7 can first send a specific signal to the control module 8, and then the control module 8 controls the fire detection camera 4 to run along the pre-set path according to the specific signal, so as to achieve the best path in this case, thereby achieving the fastest detection of the fire location, which greatly increases the accuracy.

[0040] Embodiment 9: In this embodiment, in addition to the structural features of the aforementioned embodiment, the path No. 4 in S402 is further as follows: the control module 8 controls the detection lens of the fire detection camera 4 to move to the center of gravity position of the triangular area formed by the three fire detection components 6 to perform fire detection. When no fire is detected at the center of gravity position, the control module 8 controls the lens of the fire detection camera 4 to perform spiral rotation detection at the center of gravity position until the detection of the detection triangular area is completed; Through the path setting of the fire detection camera 4, when the judgment module 7 receives the signal values ​​of the three fire detection components 6 with the highest signal values ​​that are close to or equal, the judgment module 7 can first send a specific signal to the control module 8, and then the control module 8 controls the fire detection camera 4 to run along the pre-set path according to the specific signal, so as to achieve the best path in this case, thereby achieving the fastest detection of the fire location, which greatly increases the accuracy.

When the signal values ​​of the three fire detection components 6 are close to or equal, the fire location is at the center of gravity of the triangular area at this time, because the distance from the center of gravity of the triangle to the three endpoints is closest, so the running path is also the fastest and the first to find the fire location.

[0041] Embodiment 10: In this embodiment, in addition to the structural features of the aforementioned embodiments, the path No. 5 in S402 is further as follows: at this time, the preset points of the four fire detection members 6 form a parallelogram area, and the control module 8 controls the detection lens of the fire detection camera 4 to move to the intersection of the diagonals of the parallelogram area to perform fire detection. When no fire is detected, the control module 8 controls the lens of the fire detection camera 4 to perform spiral rotation detection until the parallelogram area is detected; Through the path setting of the fire detection camera 4, when the judgment module 7 receives the signal values ​​of the three fire detection components 6 with the highest signal values ​​that are close to or equal, the judgment module 7 can first send a specific signal to the control module 8, and then the control module 8 controls the fire detection camera 4 to run according to the pre-set path according to the specific signal, so as to achieve the best path in this case, thereby achieving the fastest detection of the fire position, which greatly increases the accuracy. The above-mentioned fire detection camera 4 judges which position the fire position is close to based on the signal value of the fire detection component 6. Due to the arrangement of the fire detection components 6, there will be a situation where the signal values ​​of four fire detection components 6 are close to or equal, because four adjacent fire detection components 6 will form a parallelogram, and then the intersection of the diagonals of the parallelogram can produce equal signals of the fire detection components 6 that are close to each other, so that the signal values ​​of four fire detection components 6 appear at this time. At this time, the fire position is near the intersection of the diagonals of the parallelogram. Therefore, a spiral rotation detection is performed from the position of the intersection of the diagonals. This running path is also the fastest and the first to find the fire position. The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
