DETAILED DESCRIPTION OF THE EMBODIMENTS

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0034] Embodiment 1:

[0035] See Figures 1-5, the real-time monitoring and early warning system for anti-overturning of the canopy of the present invention includes a galvanized steel plate 1. The fixed end of the galvanized steel plate 1 is in a bent plate shape. Butterfly bolt fasteners 4 for connection and fixation are all penetrated through the fixed end of the galvanized steel plate 1. An inclination-adjustable hanging part 2 is provided at the installation end of the galvanized steel plate 1. A conductive carbon fiber rod 3 for monitoring the overturning angle of the canopy is installed on the inclination-adjustable hanging part 2. The conductive carbon fiber rod 3 is connected with a power-off alarm device through a wire. The model of the power-off alarm device is YJPD-C100 / YJPD-C380. The YJPD series power-off signal detection module will output a passive normally open / normally closed switch signal when it detects a power cut or phase loss in the power grid. The normally closed signal can be directly connected to an alarm system composed of a storage battery. The normally open signal can be used for communication signal feedback, and an intelligent telephone or GSM short message can be customized to remotely notify the duty personnel of power cut and incoming call alarms. The inclination-adjustable hanging part 2 includes a vertically arranged fixing plate 201, a horizontally hinged supporting plate 202, and a locking pin shaft 204 connected to the bottom end of the fixing plate 201 and the connecting end of the supporting plate 202. A fixing component for installing the conductive carbon fiber rod 3 is installed on the supporting plate 202. A plurality of fixing bolts 5 for installation are horizontally penetrated through the upper part of the fixing plate 201. Through the cooperation of the inclination-adjustable hanging part 2 and the fixing component, the accuracy of monitoring the anti-overturning of the canopy is greatly improved, which is convenient for all-weather monitoring and early warning when the structure is deformed, effectively preventing the situation of the steel keel reaching the limit of deformation and causing the canopy to overturn and collapse and injure people. And this device occupies a small space, has little influence on the existing structure, and a variety of fixing methods are convenient for installation and use in a narrow space, greatly improving the applicable range of this device when in use.

[0036] In the present invention, the fixing component includes a positioning groove horizontally opened at the top of the supporting plate 202, an installation cylinder 203 horizontally arranged inside the positioning groove, and an anti-slip sleeve 8 screwed and connected inside the installation cylinder 203. One end of the conductive carbon fiber rod 3 is inserted into the anti-slip sleeve 8. A plurality of annular anti-slip convex rings 9 are equally spaced and protruded on the inner wall of the anti-slip sleeve 8, and the outer end of the anti-slip convex ring 9 is in an inclined cut surface shape inclined inward. Through the cooperation of the anti-slip convex ring 9 and the anti-slip sleeve 8, the anti-dropping effect of the conductive carbon fiber rod 3 after installation can be improved, and the stability of the conductive carbon fiber rod 3 after installation can be improved.

[0037] In the present invention, the inner end of the installation cylinder 203 is closed, and a power connection block 6 for conducting electricity of the conductive carbon fiber rod 3 is installed in the inner end of the installation cylinder 203. One end of the power connection block 6 is connected with a power connection wire 7. A wire passing hole communicating with the installation groove is vertically opened at the bottom of the supporting plate 202. A through hole for the power connection wire 7 to pass through is vertically opened at the bottom rear end of the installation cylinder 203. The bottom end of the power connection wire 7 passes out from the through hole and the wire passing hole. It is convenient to form a loop when the conductive carbon fiber rod 3 monitors the steel skeleton of the canopy.

[0038] In the present invention, connecting blocks are protruded in a mutually offset manner on the bottom plate body of the fixing plate 201 and the plate body at the rear end of the supporting plate 202. A pin hole is horizontally opened on one side of the connecting block, and the rod body of the locking pin shaft 204 horizontally moves through the pin hole; and the outer end of the locking pin shaft 204 extends from the hinge joint of the fixing plate 201 and the supporting plate 202 and is sleeved with a butterfly locking nut 205. An external thread section is provided on the outer end rod body of the locking pin shaft 204 to cooperate with the butterfly locking nut 205; an anti-slip washer sleeved on the locking pin shaft 204 is installed at the inner end of the butterfly locking nut 205, and the anti-slip washer is in close contact with one side surface of the fixing plate 201 and the supporting plate 202; the cooperation of the anti-slip washer and the butterfly locking nut 205 facilitates improving the locking and positioning effect of the supporting plate 202 during angle adjustment and avoiding the change of the angle of the supporting plate 202 after adjustment.

[0039] Working principle: When the present invention is in use, first, the galvanized steel plate 1 is hung or underhung according to the selection of the end beam of the awning, and then the galvanized steel plate 1 is installed on the end beam body of the awning through the butterfly bolt fastener 4. Then, the angle-adjustable hanging part 2 is installed on the galvanized steel plate 1 through the fixing bolt 5, and the inclination angle between the supporting plate 202 and the fixing plate 201 is adjusted. Then, for the supporting plate 202 after angle adjustment, it is locked and limited after angle adjustment through the cooperation of the locking pin shaft 204 and the butterfly locking nut 205. Then, one end of the conductive carbon fiber rod 3 is inserted into the anti-slip sleeve 8 of the mounting cylinder 203, and one end of the conductive carbon fiber rod 3 is in contact with the power connection block 6 and is electrically connected to an external power-off alarm device through the power connection wire 7. Then, the inclination angle of the conductive carbon fiber rod 3 installed is adjusted again so that a section of inclined detection distance is formed between the other end of the conductive carbon fiber rod 3 and the steel keel at the bottom of the awning; after the angle is adjusted and locked, the other end of the conductive carbon fiber rod 3 is electrically connected to the power-off alarm device through a wire. When monitoring the attitude of the awning, when the end of a main steel keel of the awning reaches the maximum bearing deflection value, the displacement of the steel keel at point L0 is △F0, and the steel keel sags and touches the conductive carbon fiber rod 3, triggering an alarm when the early warning circuit is broken, and at the same time, the alarm keel part is displayed at the monitoring end of the security system; after the warning, the steel keel is repaired, the damaged parts are replaced and the end is reinforced. Then, the angle-adjustable hanging part 2 can be adjusted to reset the conductive carbon fiber rod 3; the displacement control △F0 can be calculated according to the elastic modulus of the steel keel and the designed maximum load (the calculation formula is shown in the Figure 5 drawing of the specification); there are different limit coefficients for steel keel awnings of different sizes and specifications. According to the calculation results, standard limit blocks are made, and when workers install the carbon fiber rod, they only need to control the limit size.

[0040] It should be noted that the electrical connection between the conductive carbon fiber rod 3 and the power-off alarm device, the power connection block 6, and the power connection wire 7 is a micro-current connection, not a strong-current connection, so that people and animals will not be injured if they accidentally touch it.

[0041] Embodiment 2:

[0042] In Embodiment 1, one end of the conductive carbon fiber rod 3 is inserted into the anti-slip sleeve 8 of the mounting cylinder 203, and one end of the conductive carbon fiber rod 3 is abutted against the power connection block 6, and is electrically connected to an external power-off alarm device through the power connection wire 7. Then, the inclination angle of the conductive carbon fiber rod 3 is adjusted so that there is an inclined detection distance formed at an interval between the other end thereof and the steel keel at the bottom of the canopy. When the steel keel sags and touches the conductive carbon fiber rod 3, an alarm is triggered to remind the worker that the canopy may overturn, realizing real-time monitoring and early warning of the anti-overturning of the canopy.

[0043] However, during the monitoring process, if the position of the conductive carbon fiber rod 3 changes, that is, the inclination angle of the conductive carbon fiber rod 3 changes, it may lead to an incorrect warning time. Although the inclination angle of the conductive carbon fiber rod 3 has been adjusted as expected during the initial installation, the change in the inclination angle of the conductive carbon fiber rod 3 during the monitoring process will cause the distance initially preset between the conductive carbon fiber rod 3 and the end of the steel keel to change, which may cause the system to fail to accurately issue an alarm when the end of the main steel keel reaches the maximum bearing deflection value.

[0044] In addition, if the current between the power-off alarm device and the conductive carbon fiber rod 3 is unstable, it may cause the power-off alarm device to issue an incorrect warning time. Therefore, it is necessary to evaluate the monitoring system to ensure the accuracy of the real-time monitoring and early warning system for the anti-overturning of the canopy.

[0045] The specific steps are as follows:

[0046] As Figure 5 shown, the real-time monitoring and early warning system for the anti-overturning of the canopy includes a mobile information module, a current information module, and a controller;

[0047] Mobile information module: used to collect the actual vertical distance and the preset vertical distance between the bottom surface of the conductive carbon fiber rod 3 and the top horizontal line of the fixed plate 201 during the monitoring process, and are respectively marked as and , and process the actual vertical distance and the preset vertical distance between the bottom surface of the conductive carbon fiber rod 3 and the top horizontal line of the fixed plate 201 to generate a moving distance deviation coefficient , and transmit the generated data to the controller;

[0048] Current information module: used to collect the instability degree of the current between the conductive carbon fiber rod 3 and the power-off alarm device during the monitoring process, denoted as the current instability coefficient, and mark the current instability coefficient as , and transmit the generated data to the controller;

[0049] Controller: Process the uploaded moving distance deviation coefficient and the current instability coefficient to generate an evaluation coefficient , and compare the evaluation coefficient with the pre-designed reference threshold of the evaluation coefficient and generate an alarm signal based on the comparison result to issue an alarm.

[0050] It should be noted that the alarm signal generated by the controller and the alarm issued are different from the alarm triggered when the steel keel sags and touches the conductive carbon fiber rod 3 in Embodiment 1. In actual application scenarios, the alarm sounds and alarm durations of the two are also different, which should be determined according to the actual usage situation for easy distinction between the two alarms.

[0051] The specific operation is as follows:

[0052] Moving distance deviation coefficient: The difference between the actual vertical distance from the bottom surface of the conductive carbon fiber rod 3 to the horizontal line at the top of the fixing plate 201 and the preset vertical distance; as described in Embodiment 1, after adjusting the position of the conductive carbon fiber rod 3, there is a fixed vertical distance from the bottom surface of the conductive carbon fiber rod 3 to the horizontal line at the top of the fixing plate 201, and this distance is the preset vertical distance. If during the actual monitoring process, the actual vertical distance from the bottom end of the conductive carbon fiber rod 3 to the horizontal line at the top of the fixing plate 201 is inconsistent, it is very likely that the position of the conductive carbon fiber rod 3 will change, which may cause the steel keel end not to touch the conductive carbon fiber rod 3 when it reaches the maximum bearing deflection value, resulting in an incorrect early warning; therefore,

[0053] it is very important to ensure that during the actual monitoring process, the actual vertical distance from the bottom surface of the conductive carbon fiber rod 3 to the horizontal line at the top of the fixing plate 201 is always consistent with the preset vertical distance;

[0054] The acquisition logic of the moving distance deviation coefficient is: , where is the moving distance deviation coefficient, is the actual vertical distance from the bottom surface of the conductive carbon fiber rod 3 to the horizontal line at the top of the fixing plate 201, is the preset vertical distance from the bottom surface of the conductive carbon fiber rod 3 to the horizontal line at the top of the fixing plate 201;

[0055] It should be noted that both the actual vertical distance from the bottom surface of the conductive carbon fiber rod 3 to the horizontal line at the top of the fixing plate 201 and the preset vertical distance can be obtained through the movement information module;

[0056] As can be seen from the calculated expression, the larger the performance value of the moving distance deviation coefficient, the lower the accuracy of the real-time monitoring and early warning system for the anti-overturning of the canopy. At this time, it is more necessary to issue an alarm to remind the staff that there is a problem with the real-time monitoring and early warning system for the anti-overturning of the canopy, and the evaluation coefficient is larger; the smaller the performance value of the moving distance deviation coefficient, the higher the accuracy of the real-time monitoring and early warning system for the anti-overturning of the canopy, and the smaller the evaluation coefficient.

[0057] It should be noted that whether the actual vertical distance between the bottom surface of the conductive carbon fiber rod 3 and the top horizontal line of the fixed plate 201 is greater than or less than the preset vertical distance will cause errors in the real-time monitoring and early warning of the anti-overturning of the canopy. When the actual vertical distance is greater than the preset vertical distance, the early warning time becomes slower; when the actual vertical distance is less than the preset vertical distance, the early warning time becomes faster.

[0058] Current instability coefficient: It refers to the degree of instability of the current between the conductive carbon fiber rod 3 and the power-off alarm device during the actual monitoring process; if the degree of instability of the current between the conductive carbon fiber rod 3 and the power-off alarm device is higher, it may cause the power-off alarm device not to issue an alarm when the end of the steel keel touches the conductive carbon fiber rod due to the instability of the current, which may lead to the overturning of the canopy; therefore, it is very important to ensure the stability of the current between the conductive carbon fiber rod 3 and the power-off alarm device to ensure that the power-off alarm device can issue an early warning in time.

[0059] The acquisition logic of the current instability coefficient is as follows:

[0060] S1. Obtain the actual current values between the conductive carbon fiber rod 3 and the power-off alarm device at different times within the time T, and calibrate the actual current values as , representing the serial number of the actual current values between the conductive carbon fiber rod 3 and the power-off alarm device at different times within the time T, , c is a positive integer;

[0061] S2. Calculate the standard deviation of the actual current values between the conductive carbon fiber rod 3 and the power-off alarm device at different times within the time T and calibrate the standard deviation as , and the standard deviation The calculation formula is: ; ;

[0062] Among them, is the average value of the actual current values between the conductive carbon fiber rod 3 and the power-off alarm device at different times within the time T, and the acquisition expression is: ; ;

[0063] S3. Calculate the current instability coefficient, and the obtained expression is: ; It can be seen from the calculated expression that the larger the manifestation value of the current instability coefficient, the lower the accuracy of the real-time monitoring and early warning system for the anti-overturning of the canopy. At this time, it is more necessary to give an alarm to remind the staff that there is a problem with the real-time monitoring and early warning system for the anti-overturning of the canopy, and the evaluation coefficient is larger; the smaller the manifestation value of the current instability coefficient, the higher the accuracy of the real-time monitoring and early warning system for the anti-overturning of the canopy, and the smaller the evaluation coefficient.

[0064] It should be noted that the actual current values between the conductive carbon fiber rods 3 and the power-off alarm device at different moments within the T time can be obtained through the current information module. In addition, the selected T time can be determined by specific staff according to the actual situation and is not limited here;

[0065] The obtained moving distance deviation coefficient and the current instability coefficient are comprehensively processed, and a data processing model is established to generate an evaluation coefficient , and the formula is: ;

[0066] In the formula, , are the preset proportionality coefficients of the moving distance deviation coefficient and the current instability coefficient respectively, and , are both greater than 0.

[0067] The evaluation coefficient is compared with the pre-designed evaluation coefficient reference threshold ;

[0068] If the evaluation coefficient is less than the pre-designed evaluation coefficient reference threshold , it means that the accuracy of the real-time monitoring and early warning system for the anti-overturning of the canopy is relatively high, and it can accurately monitor the overturning phenomenon of the canopy and can timely issue an early warning to remind the staff; if the evaluation coefficient is greater than the pre-designed evaluation coefficient reference threshold , it means that the accuracy of the real-time monitoring and early warning system for the anti-overturning of the canopy is relatively low. In order to timely remind the staff when the canopy overturns, at this time, the controller first issues an alarm to remind the staff that there is a problem with the real-time monitoring and early warning system for the anti-overturning of the canopy and needs to be repaired in time, and at the same time observe the phenomenon of the canopy to prevent the sudden overturning of the canopy from causing harm to personnel.

[0069] In addition, it should be noted again that the alarm signal generated by the controller and the alarm issued are different from the alarm triggered when the steel keel sags and touches the conductive carbon fiber rod 3 described in Embodiment 1. In actual application scenarios, the alarm sounds and alarm durations of the two are also different, and specifically depend on the actual usage situation to facilitate the distinction between the two alarms.

[0070] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent replacements or changes should be covered within the protection scope of the present invention.
