Description

Technical Field

[0001] The present application relates to the technical field of jacking construction measurement, and in particular to an intelligent monitoring method, device, electronic equipment and storage medium for bridge jacking construction. Background Art

[0002] The bridge jacking method refers to the method of building the beam body in sections on one side of the existing line when the bridge crosses the existing line, and then using jacks to push it through the line. The advantage of jacking construction is that it does not require large machinery, and only needs to push the built beam section along the axis by jacking repeatedly. Because the jacking method has the characteristics of relatively light equipment, good structural integrity, little impact on the surrounding environment, and saving construction land, it is widely used in bridge construction under restricted conditions such as crossing rivers, roads, and railways. However, the jacking construction method also has certain technical defects. Due to the control error of the jack during the jacking construction, the uneven traction force on both sides of the beam body, and the excessive deflection of the guide beam, the beam body will be laterally offset, affecting the construction quality and construction safety. In the related technology, the monitoring method for controlling the offset of the beam body adopts the monitoring method of the total station. The monitoring method of the total station can only measure static targets. For the more complex dynamic construction environment such as jacking construction, the monitoring range of the total station is limited, manual intervention is required, and the construction efficiency is low.

DETAILED DESCRIPTION

[0019] In order to enable technicians in this field to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below in conjunction with the drawings in the embodiments of this specification. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments.

[0021] In the description of the embodiments of the present application, the meaning of the term "multiple" refers to two or more. For example, multiple systems refer to two or more systems, and multiple screen terminals refer to two or more screen terminals. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the indicated technical features.

[0022] The embodiment of the present application provides an intelligent monitoring method, device, electronic device and readable storage medium for bridge jacking construction. The intelligent monitoring method for bridge jacking construction first sets a pair of laser transmitters and receivers on the side of the bridge. The positions of the paired laser transmitters and receivers correspond to each other and there is a preset deviation threshold from the bridge. The laser transmitters and receivers are set to provide a basis for intelligent monitoring; the laser transmitter is controlled to emit a laser signal, the receiver is controlled to receive the laser signal, and the laser signal is converted into a signal to output an analog signal so that the deviation can be judged according to the analog signal later; when the analog signal indicates a first value, an alarm message is issued and the indicator light flashes, and a control instruction is issued. The control instruction is used to control the vibration of a Bluetooth bracelet with a prompt. The vibration of the Bluetooth bracelet can prompt that the deviation has occurred during the bridge jacking process. It can be achieved without manual intervention, thereby improving the construction efficiency. According to the control instruction and the deviation threshold, the lateral deviation of the bridge beam is corrected to obtain the corrected deviation, which can be corrected to improve the construction efficiency. Wherein, the first value indicates that the receiver does not receive the laser signal emitted by the laser transmitter. By using signal transmission between laser transmitters and receivers, the deviation of the beam can be monitored and measured in real time, and the monitoring results can be fed back. The deviation can be estimated and corrected based on the feedback without human intervention, which reduces labor costs and improves construction efficiency.

[0023] It should be noted that the intelligent monitoring method for bridge jacking construction is mainly used for monitoring during the construction of large-span bridges or bridges with large lateral height differences, and can avoid beam deviation. Through real-time monitoring and measurement, and feedback of monitoring results, deviation estimation and correction are carried out based on feedback, without manual intervention, which reduces labor costs and improves construction efficiency.

[0024] The technical solution provided in the embodiments of the present application is further described below in conjunction with the accompanying drawings.

[0025] Reference Figure 1 , Figure 1 1 is a flow chart of the intelligent monitoring method for bridge jacking construction provided by the embodiment of the present application. The intelligent monitoring method for bridge jacking construction is applied to the intelligent monitoring device for bridge jacking construction, and the intelligent monitoring method for bridge jacking construction is executed by a processor in an electronic device or a readable storage medium. The intelligent monitoring method for bridge jacking construction includes steps S100, S200, S300 and S400.

[0026] Step S100, a pair of laser transmitters and receivers are arranged on the side of the bridge, the positions of the pair of laser transmitters and receivers correspond to each other, and there is a preset offset threshold between the pair and the bridge.

[0027] In one embodiment, in order to monitor whether the beam body is deflected during the bridge jacking construction process, a pair of laser transmitters and receivers are set on the side of the bridge. The laser transmitter and receiver are set to exist in pairs to receive signals and make intelligent judgments based on the signals without manual intervention. The positions of the paired laser transmitters and receivers correspond to each other, that is, the laser transmitter and receiver are on a straight line parallel to the beam body or in the same direction of jacking. The laser transmitter is set at the starting end of the bridge construction, and the receiver is set in the forward direction of the bridge construction. In addition, the laser transmitter and receiver are both at a preset deviation threshold from the bridge, so that they can be accurately monitored when the beam body deviates. Among them, the deviation threshold is the maximum error value that can allow the beam body to deviate, and the deviation threshold can be set within a range less than or equal to the maximum error value according to needs.

[0028] In one embodiment, the process of setting up a pair of laser transmitters and receivers on the side of a bridge includes: setting up a group of laser transmitters and receivers on both sides of the bridge respectively; debugging and calibrating each group of laser transmitters and receivers respectively to obtain a pair of laser transmitters and receivers.

[0029] Specifically, a group of laser transmitters and receivers are set on both sides of the bridge to monitor the offset on both sides of the beam. After the position is determined, each group of laser transmitters and receivers on both sides are debugged and calibrated to obtain paired laser transmitters and receivers. Through debugging and calibration, the receiver can accurately receive the laser signal emitted by the laser transmitter, so as to perform subsequent monitoring and judgment based on the signal.

[0030] It should be noted that in addition to the laser transmitter and receiver, an alarm module and a Bluetooth bracelet are also provided. The alarm module and the Bluetooth bracelet are provided in conjunction with the laser transmitter and the receiver, that is, an alarm module and a Bluetooth bracelet are provided corresponding to each set of laser transmitters and receivers. The monitoring staff wears Bluetooth bracelets, and the two sets of Bluetooth bracelets are worn on the two hands of the monitoring staff. The Bluetooth bracelets can be set in different colors, and Bluetooth bracelets of different colors can also be worn at different positions on the same hand. A set of laser transmitters, receivers, alarm modules and Bluetooth bracelets are provided on both sides of the bridge for signal transmission, reception and signal processing, so as to carry out real-time monitoring and realize intelligent monitoring.

[0031] like Figure 2As shown, a group of laser transmitters, receivers, alarm modules and Bluetooth bracelets are respectively arranged on both sides of the bridge, which are respectively represented as laser transmitter A, receiver A, alarm module A, Bluetooth bracelet A, laser transmitter B, receiver B, alarm module B, and Bluetooth bracelet B. Laser transmitter A and receiver A have a preset offset threshold from the bridge, and laser transmitter B and receiver B have a preset offset threshold from the bridge. Receiver A, alarm module A, Bluetooth bracelet A, receiver B, alarm module B, and Bluetooth bracelet B are all arranged along the top-pushing direction. By making the above settings, material support is provided for subsequent real-time monitoring without manual intervention.

[0032] In one embodiment, each set of laser emitters and receivers is debugged and calibrated to obtain a pair of laser emitters and receivers, including but not limited to the following steps: Step S101, setting a laser emitter on one side of the bridge, and adjusting the position and orientation of the laser emitter so that the center of the laser emitter has a lateral offset from the beam of the bridge, wherein the lateral offset is equal to the offset threshold.

[0033] In some possible embodiments of the present application, firstly, a laser transmitter A or a laser transmitter B is set on one side of the bridge, and the position and orientation of the laser transmitter A or the laser transmitter B are adjusted, wherein the position refers to a position that enables the center of the laser transmitter to have a lateral offset from the beam of the bridge, and the orientation is a direction corresponding to the receiver, so that a laser signal is emitted toward the receiver so that the receiver can receive the laser signal. Among them, the lateral offset is equal to the offset threshold, and the lateral offset may also be less than the offset threshold, and it can be within the maximum error range. By adjusting the position and orientation of the laser transmitter to ensure that the positions of the laser transmitter and the receiver correspond, a paired device setting is performed.

[0034] Step S102, turning on the laser transmitter and rotating the laser transmitter so that the laser light spot emitted by the laser transmitter hits the mirror surface of the receiver.

[0035] In some possible embodiments of the present application, according to the laser transmitter adjusted in step S101, the laser transmitter is turned on and rotated, at which time, the receiver may not be adjusted or may not be adjusted, so that the laser light spot emitted by the laser transmitter hits the mirror surface of the receiver. The mirror surface of the receiver may also be rotated without adjusting the direction of the laser transmitter, so that the laser light spot emitted by the laser transmitter hits the mirror surface of the receiver, thereby realizing the mutual correspondence between the laser transmitter and the receiver and receiving the signal.

[0036] Step S103, when the indicator light is always on, laser light spots are continuously generated to form a laser grating.

[0037] In some possible embodiments of the present application, signals are transmitted according to the laser transmitter and receiver, and the alarm module controls the indicator light state according to the laser signal received by the receiver. When the indicator light is always on, it indicates that the laser signal emitted by the laser transmitter can be normally received by the receiver, and laser light spots are continuously generated to form a laser grating, so as to form a continuous signal for subsequent signal analysis and judgment. By forming a laser grating, it is indicated that the laser transmitter and receiver are properly set, and whether the beam body is deviated during the jacking process can be accurately measured.

[0038] It should be noted that laser transmitter A or laser transmitter B is set on the other side of the bridge, and the setting and adjustment methods of the laser transmitter and receiver are similar to those on the other side, which will not be repeated here.

[0039] Step S200, controlling the laser transmitter to transmit a laser signal, controlling the receiver to receive the laser signal, and converting the laser signal into an analog signal.

[0040] In one embodiment, when a pair of laser transmitters and receivers are set, during the construction process, the laser transmitter is controlled to transmit a laser signal, and the receiver is controlled to receive the laser signal transmitted by the laser transmitter. The receiver has two representation states: receiving the laser signal and not receiving the laser signal. The received laser signal is represented as 1, and the unreceived laser signal is represented as 0. The laser signal is converted into an analog signal to facilitate subsequent calculations.

[0041] In one embodiment, the laser signal is converted into an analog signal, which includes but is not limited to the following steps: Step S210, converting the laser signal into an electrical signal, and preprocessing the electrical signal to obtain a preprocessed signal.

[0042] In some possible embodiments of the present application, the received laser signal is converted into an electrical signal by using a preset photoelectric converter, and the photoelectric converter may be a photodiode or a phototransistor. Since there may be noise in the signal, the electrical signal is preprocessed to obtain a preprocessed signal, which can improve the accuracy of the signal. The preprocessing operation includes amplification, filtering, etc.

[0043] Step S220, performing signal screening from the preprocessed signal to obtain an analog signal.

[0044] In some possible embodiments of the present application, the preprocessed signal can be represented as a digital signal and an analog signal, and the analog signal in the preprocessed signal can be screened out to obtain the analog signal. The digital signal can also be converted into an analog signal, and the analog signal can be obtained to facilitate subsequent identification processing.

[0045] Step S300, when the analog signal indicates a first value, an alarm message is issued and the indicator light flashes, and a control instruction is issued. The control instruction is used to control the vibration of the Bluetooth bracelet with a prompt. The lateral deviation of the bridge beam is corrected according to the control instruction and the deviation threshold to obtain the corrected deviation, wherein the first value indicates that the receiver has not received the laser signal emitted by the laser transmitter.

[0046] In one embodiment, the first value may be 0 or a non-existent character symbol, which is used to indicate that the receiver has not received the laser signal emitted by the laser transmitter. When the analog signal indicates the first value, it indicates that the receiver has not received the laser signal, indicating that the beam body has been offset, so that the offset of the beam body can be accurately monitored. An alarm message is issued and the indicator light flashes. The flashing indicator light is used to prompt the staff to suspend the construction inspection. When the indicator light flashes, the staff may not be able to detect it as soon as possible. An alarm message is issued for prompting, and a control instruction is issued. The control instruction is used to control the vibration of the Bluetooth bracelet with a prompt. The staff hears the alarm prompt and notices the vibration of the bracelet, and can check it in time. Multiple reminders can be achieved through alarm messages, flashing indicator lights and Bluetooth bracelets, so that timely viewing can be carried out, and reminders can be made through multiple indicators so that a certain failure causes misjudgment, thereby delaying the construction period.

[0047] In another embodiment, after converting the laser signal into an analog signal, the intelligent monitoring method for bridge jacking construction further includes but is not limited to step S400: Step S400: When the analog signal indicates a second value, the bridge jacking construction proceeds normally, and the second value indicates that the receiver receives the laser signal emitted by the laser transmitter.

[0048] In one embodiment, the second value may be 1 or an existing character symbol, which indicates that the receiver receives the laser signal emitted by the laser transmitter, corresponding to the first value. When the analog signal indicates the second value, it indicates that the receiver receives the laser signal, indicating that the beam body has not deviated, and the bridge jacking construction is proceeding normally, so that the beam body deviation can be accurately monitored. It should be noted that when the receiver receives the laser signal emitted by the laser transmitter, the indicator light is always on to distinguish it from an abnormal state.

[0049] In one embodiment, the control instruction is also used to indicate that the lateral deviation of the bridge beam is greater than the deviation threshold, such as Figure 3 As shown, the lateral deviation of the bridge beam is corrected according to the control instruction and the deviation threshold to obtain the corrected deviation, including but not limited to the following steps: Step S310, estimating the estimated lateral displacement value of the beam body according to the control instruction.

[0050] In some possible embodiments of the present application, since the control instruction also indicates that the lateral deviation of the bridge beam is greater than the deviation threshold, multiple receivers can be set near the receiver, that is, one laser transmitter corresponds to multiple receivers, for estimating the lateral deviation of the beam. Among the multiple receivers set up, the multiple receivers are numbered, and only the laser signal received by the receiver consistent with the laser transmitter indicates that the beam has a lateral deviation. According to the multiple receivers set up, the generated control instruction includes the values ​​corresponding to the multiple receivers. According to the control instruction, the receiver that receives the laser signal can be obtained, and then the deviation value of the signal can be calculated, thereby estimating the estimated deviation value of the lateral deviation of the beam.

[0051] Step S320, calculating the estimated deviation value and the deviation threshold to obtain a calculation result.

[0052] In some possible embodiments of the present application, the difference between the estimated deviation value and the deviation threshold is calculated. The estimated deviation value can be subtracted from the deviation threshold to obtain a calculation result; or the deviation threshold can be subtracted from the estimated deviation value, and then the absolute value is calculated to obtain a calculation result, so as to subsequently perform trend simulation based on the calculation result.

[0053] Step S330, simulating the movement of the bridge beam according to the calculation results to determine the predicted deviation position.

[0054] like Figure 4 As shown, the trend of the bridge beam is simulated according to the calculation results to determine the predicted deviation position, including but not limited to the following steps: Step S331, simulating the bridge construction using a preset modeling model, and adjusting the bridge pushing parameters in the modeling model according to the calculation results.

[0055] In some possible embodiments of the present application, the preset modeling model may be a BIM model. The preset modeling model is used to simulate the bridge construction. During the simulated construction process of the modeling model, the value of the calculation result is gradually reduced, and the beam body is continuously pushed forward to obtain the construction direction of the beam body, and the direction is compared with the direction before adjustment, and the bridge pushing parameters are adjusted to facilitate the subsequent determination of the deviation position.

[0056] Step S332, during the adjustment process, the simulation indicator light is always on to determine the predicted deviation position.

[0057] In some possible embodiments of the present application, the modeling model can also simulate an indicator light, and whether there is a deviation can be determined based on the brightness state of the indicator light. When the indicator light is always on, it indicates that the lateral deviation of the beam has been corrected. When the indicator light flashes, it indicates that the beam is still in a lateral deviation. During the adjustment process, the predicted deviation position can be determined by the state of the indicator light, so that corrections can be made at the predicted deviation position later, speeding up the construction progress and improving construction efficiency.

[0058] Step S340, correcting the predicted deviation position to obtain a corrected deviation position.

[0059] In some possible embodiments of the present application, based on the determined predicted deviation position, the angle between the predicted deviation position and the normal pushing direction is calculated to obtain a corrected deviation so that during the construction process, construction can be carried out according to the corrected deviation, thereby reducing the possibility of trial and error in actual construction and improving construction efficiency.

[0060] like Figure 5 As shown, the embodiment of the present application provides an intelligent monitoring device 100 for bridge jacking construction, which sets a pair of laser transmitters and receivers on the side of the bridge, and the positions of the paired laser transmitters and receivers correspond to each other, and there is a preset deviation threshold from the bridge. The laser transmitters and receivers are set to provide a basis for intelligent monitoring; the signal processing module 110 controls the laser transmitter to emit a laser signal, controls the receiver to receive the laser signal, and converts the laser signal into a signal, outputs an analog signal, so that the deviation judgment is performed according to the analog signal later; when the deviation judgment module 120 indicates a first value, an alarm message is issued and the indicator light flashes, and a control instruction is issued, and the control instruction is used to control the vibration of the Bluetooth bracelet with prompts, and the vibration of the Bluetooth bracelet can prompt that the deviation occurs during the bridge jacking process, which can be achieved without manual intervention, thereby improving the construction efficiency, and the lateral deviation of the bridge beam body is corrected according to the control instruction and the deviation threshold, and the corrected deviation is obtained, which can be corrected, thereby improving the construction efficiency. Among them, the first value indicates that the receiver does not receive the laser signal emitted by the laser transmitter.

[0061] It should be noted that the signal processing module 110 is connected to the deviation judgment module 120. The above-mentioned intelligent monitoring method for bridge jacking construction is applied to the intelligent monitoring device 100 for bridge jacking construction. The intelligent monitoring device 100 for bridge jacking construction provides a basis for intelligent monitoring by setting a pair of laser transmitters and receivers on the side of the bridge. The positions of the paired laser transmitters and receivers correspond to each other, and there is a preset deviation threshold from the bridge. The laser transmitters and receivers are set up to provide a basis for intelligent monitoring; the laser transmitter is controlled to emit a laser signal, the receiver is controlled to receive the laser signal, and the laser signal is converted into a signal, and an analog signal is output, so that the deviation judgment is performed according to the analog signal later; when the analog signal indicates a first value, an alarm message is issued and the indicator light flashes, and a control instruction is issued. The control instruction is used to control the vibration of the Bluetooth bracelet with prompts. The vibration of the Bluetooth bracelet can prompt that the deviation occurs during the bridge jacking process, which can be achieved without manual intervention, thereby improving the construction efficiency. According to the control instruction and the deviation threshold, the lateral deviation of the beam of the bridge is corrected, and the corrected deviation is obtained, which can be corrected, thereby improving the construction efficiency. Among them, the first value indicates that the receiver does not receive the laser signal emitted by the laser transmitter. By using signal transmission between laser transmitters and receivers, the deviation of the beam can be monitored and measured in real time, and the monitoring results can be fed back. The deviation can be estimated and corrected based on the feedback without human intervention, which reduces labor costs and improves construction efficiency.

[0062] Specifically, a group of laser transmitters and receivers are set on both sides of the bridge to monitor the offset on both sides of the beam. After the position is determined, each group of laser transmitters and receivers on both sides are debugged and calibrated to obtain paired laser transmitters and receivers. Through debugging and calibration, the receiver can accurately receive the laser signal emitted by the laser transmitter, so as to perform subsequent monitoring and judgment based on the signal.

[0063] First, set the laser transmitter A or laser transmitter B on one side of the bridge, and adjust the position and direction of the laser transmitter A or laser transmitter B. The position refers to the position that can make the center of the laser transmitter have a lateral offset from the beam of the bridge, and the direction is the direction corresponding to the receiver, so that the laser signal is emitted to the receiver method so that the receiver can receive the laser signal. Among them, the lateral offset is equal to the offset threshold, and the lateral offset can also be less than the offset threshold, within the maximum error range. By adjusting the position and direction of the laser transmitter, the position of the laser transmitter and the receiver are ensured to correspond, so as to set the equipment in pairs. According to the adjusted laser transmitter, turn on the laser transmitter and rotate the laser transmitter. At this time, the receiver can be adjusted or not adjusted, so that the laser light spot emitted by the laser transmitter hits the mirror of the receiver. The mirror of the receiver can also be rotated without adjusting the direction of the laser transmitter, so that the laser light spot emitted by the laser transmitter hits the mirror of the receiver, thereby realizing the mutual correspondence between the laser transmitter and the receiver and receiving the signal. When the indicator light is always on, laser light spots are continuously generated to form a laser grating, and the paired setting is completed.

[0064] In another embodiment, since the control instruction also indicates that the lateral displacement of the bridge beam is greater than the displacement threshold, multiple receivers can be set near the receiver, that is, one laser transmitter corresponds to multiple receivers, for estimating the lateral displacement of the beam. Among the multiple receivers set, the multiple receivers are numbered, and only the laser signal received by the receiver consistent with the laser transmitter indicates that the beam has not been lateral displaced. It should be noted that among the multiple receivers, only one receiver is adjusted to be consistent with the laser transmitter.

[0065] In one embodiment, the signal processing module 110 converts the received laser signal using a preset photoelectric converter to obtain an electrical signal. The photoelectric converter may be a photodiode or a phototransistor. Since there may be noise in the signal, the electrical signal is preprocessed to obtain a preprocessed signal, which can improve the accuracy of the signal. Among them, the preprocessing operation includes amplification, filtering, etc. The preprocessed signal can be represented as a digital signal and an analog signal. The analog signal in the preprocessed signal can be screened out to obtain an analog signal. The digital signal can also be converted into an analog signal, and the analog signal can be obtained to facilitate subsequent identification processing.

[0066] In one embodiment, during the calculation process of correcting the deviation, the deviation judgment module 120 generates a control instruction including values ​​corresponding to the multiple receivers according to the multiple receivers set. According to the control instruction, the receiver that receives the laser signal can be obtained, and then the deviation value of the signal is calculated, so as to estimate the estimated deviation value of the lateral deviation of the beam body. The difference between the estimated deviation value and the deviation threshold value can be obtained by subtracting the deviation threshold value from the estimated deviation value to obtain the calculation result; or the estimated deviation value can be subtracted from the deviation threshold value, and then the absolute value is calculated to obtain the calculation result, so as to perform trend simulation according to the calculation result later.

[0067] Specifically, the deviation judgment module 120 simulates the bridge construction using a preset modeling model. During the simulation construction process of the modeling model, the value of the calculation result is gradually reduced, and the beam body is simulated to continue to push the beam body, so as to obtain the construction direction of the beam body, and compare it with the direction before adjustment, and adjust the bridge pushing parameters so as to determine the deviation position later. The modeling model can also simulate an indicator light, and the deviation can be judged according to the brightness state of the indicator light. When the indicator light is always on, it indicates that the lateral deviation of the beam body has been corrected. When the indicator light flashes, it indicates that the beam body is still in lateral deviation. During the adjustment process, the predicted deviation position can be determined by the state of the indicator light, so as to correct it at the predicted deviation position later, speed up the construction progress, and improve the construction efficiency. According to the determined predicted deviation position, the angle between the predicted deviation position and the normal pushing direction is calculated to obtain the corrected deviation, so that during the construction process, construction can be carried out according to the corrected deviation, thereby reducing the possibility of trial and error in actual construction and improving construction efficiency.
