[0073] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0074] Please refer to Figure 1 The present application discloses a bridging auxiliary method, comprising the following steps:

[0075] S110: Acquire observation data information and bridge equipment information.

[0076] It is understandable that the environment of bridge erection operations is relatively random, and a lot of geographic information is unknown in actual bridge erection operations. According to the specific practice of bridge erection operations, the following application provides a scenario where the geographic information of gullies needs to be surveyed: before the bridge erection operation, the width of the gully area is unknown, and the depth of the gully area is unknown. When the staff is unknown about the geographic information of the gully, it is difficult to quickly determine the starting point and the target point of the bridge erection operation. Therefore, a simple survey of the nearby geographic information is required.

[0077] Specifically, the staff needs to select at least one point on the opposite bank of the gully as the preset target point for the bridge erection operation. The preset target point can be understood as the bridge loading point, that is, the completion point of the bridge erection operation. Usually, the preset target point can be changed according to the erection requirements.

[0078] A measuring instrument is set up near the starting point of the bridge erection operation. The measuring instrument has at least the function of distance measurement and angle measurement, and is used to measure the geographic information of the preset target point relative to the measuring instrument. When the measuring instrument is working, the measuring instrument is used as an observation point to measure the observation data information of the preset target point relative to the observation point. For example, the distance of the preset target point relative to the observation point, the angle between the straight line drawn by the preset target point relative to the observation point and the horizontal line, and the height of the observation point relative to the ground.

[0079] The bridge equipment information is related to the model of the bridge equipment. The bridge equipment described in this application is manifested as a mechanized bridge in a specific application scenario, such as a 69A light mechanized bridge, a GQL120A light mechanized bridge, an 84A heavy mechanized bridge, and a GQL111 heavy mechanized bridge. The mechanized bridge is composed of a plurality of bridge body units, and bridge support legs are arranged between adjacent bridge body units.

[0080] It should be pointed out that different types of bridge equipment have different parameters. According to the model of the bridge equipment, at least the bridge equipment information such as the maximum length of the bridge equipment erection, the length of the bridge unit, and the adjustment range of the bridge support legs can be determined.

[0081] S120: Calculate the parameter information required for bridge building according to the observed data information.

[0082] It can be understood that the parameter information required for bridge erection at least includes the distance of the preset target point relative to the ground projection of the observation point, the required number of bridge units, the required number of bridge support legs, and the distance between each bridge unit and the landing point of the bridge support leg. Among them, the required number of bridge units can be understood as the number of bridge units required to complete the bridge erection operation. The required number of bridge support legs can be understood as the number of bridge unit groups required to complete the bridge erection operation. The distance between each bridge unit and the landing point of the bridge support leg can be understood as the distance between the bridge support leg and the gully contact surface relative to the bridge unit in a single-section bridge unit.

[0083] Please refer to Figure 2 , the following describes the specific implementation process of calculating the parameter information required for bridge building based on the observation data information:

[0084] Furthermore, in a specific implementation manner provided in the present application, calculating the distance of a preset target point relative to the ground projection of an observation point specifically includes:

[0085] According to the distance of the preset target point relative to the observation point, the angle between the straight line drawn by the preset target point relative to the observation point and the horizontal line, and the height of the observation point relative to the ground, the angle between the straight line drawn by the preset target point relative to the preset starting point and the horizontal line is calculated by the following formula;

[0086]

[0087] Where h is the height of the observation point relative to the ground, GT is the distance between the preset target point and the observation point, θ1 is the angle between the straight line drawn from the preset target point to the observation point and the horizontal line, and θ2 is the angle between the straight line drawn from the preset target point to the preset starting point and the horizontal line;

[0088] According to the distance of the preset target point relative to the observation point, the angle between the straight line drawn by the preset target point relative to the observation point and the horizontal line, the height of the observation point relative to the ground, and the angle between the straight line drawn by the preset target point relative to the preset starting point and the horizontal line, the distance of the preset target point relative to the ground projection of the observation point is calculated by the following formula;

[0089]

[0090] Where OT is the distance between the preset target point and the ground projection of the observation point.

[0091] The derivation process of the above formula is as follows:

[0092] Given that the height of the observation point relative to the ground is GO=h, the distance of the preset target point relative to the observation point is GT, and the angle between the straight line drawn from the preset target point to the observation point and the horizontal line is θ1, then according to Figure 2 The geometric relationship given in

[0093] G1T=GT·sinθ1

[0094] GO=G1O′=h

[0095] O′T=G1T-G1O′=G1T-h

[0096] GG1=OO′=GT·cosθ1

[0097] Where GG1 is the horizontal distance between the preset target point and the observation point.

[0098] According to the trigonometric theorem, we have

[0099]

[0100]

[0101] Where h is the height of the observation point relative to the ground, GT is the distance between the preset target point and the observation point, θ1 is the angle between the straight line drawn from the preset target point to the observation point and the horizontal line, θ2 is the angle between the straight line drawn from the preset target point to the preset starting point and the horizontal line, and OT is the distance between the preset target point and the ground projection of the observation point.

[0102] Further, in a specific implementation manner provided in the present application, calculating the number of bridge units and the number of bridge support legs specifically includes:

[0103] According to the distance of the preset target point relative to the ground projection of the observation point and the length of the bridge unit, the number of bridge units and the number of bridge support legs are calculated by the following formula;

[0104] N0=OT / P;

[0105] M = N0-1;

[0106] Where N0 is the number of bridge units, OT is the distance between the preset target point and the ground projection of the observation point, P is the length of a single bridge section, and M is the number of bridge support legs.

[0107] It should also be pointed out that in the formula for calculating the number of bridge units, the results of calculating the number of bridge units all use the rule of rounding up.

[0108] Further, in a specific implementation manner provided in the present application, calculating the distance between each bridge unit and the landing point of the bridge support leg specifically includes:

[0109] Calculate the position information of the landing point of each bridge support leg relative to the preset target point according to the required number of bridge body units and the length of the bridge body unit;

[0110] According to the position information of the landing point of each bridge support leg relative to the preset target point, the distance of each bridge support leg landing point relative to the observation point and the angle between the straight line drawn by the landing point of each bridge support leg relative to the observation point and the horizontal line are measured;

[0111] According to the distance between the landing point of each bridge support leg and the observation point, and the angle between the straight line drawn from the landing point of each bridge support leg and the observation point and the horizontal line, the distance between each bridge unit and the landing point of the bridge support leg is calculated by the following formula, which is expressed as follows:

[0112]

[0113]

[0114] In the formula, the value range of n is from 1 to N0-1. is the distance between each bridge unit and the landing point of the bridge support leg, It is the angle between the straight line drawn from the landing point of each bridge support leg relative to the observation point and the horizontal line. is the distance between the landing point of each bridge support leg and the observation point, is the distance between the contact point between each bridge support leg and the single bridge section relative to the preset target point, and

[0115] It is understandable that the ground undulations in the gully are complex, and it is difficult to directly calculate the distance between each bridge unit and the landing point of the bridge support leg. Therefore, before calculating the distance between each bridge unit and the landing point of the bridge support leg, it is necessary to determine the position information of each bridge support leg landing point relative to the preset target point. Specifically, the length of each bridge unit group, that is, the horizontal distance of each bridge support leg landing point relative to the preset target point, can be calculated based on the required number of bridge units and the length of the bridge unit. According to the horizontal distance of each bridge support leg landing point relative to the preset target point and the distance of the preset target point relative to the ground projection of the observation point, the horizontal distance between each bridge support leg landing point and the observation point can be calculated. Afterwards, according to the horizontal distance between each bridge support leg landing point and the observation point, the distance between each bridge support leg landing point and the observation point and the angle between the straight line drawn by each bridge support leg landing point relative to the observation point are measured by measuring instruments. Then, according to the trigonometric theorem, the distance between each bridge unit and the landing point of the bridge support leg can be calculated.

[0116] Specifically, the derivation process of the above formula is as follows:

[0117] Calculate the horizontal distance between the preset target point and each inverse bridge support leg in sequence:

[0118]

[0119] In the formula, the value range of n is from 1 to N0-1. is the horizontal distance between the preset target point and each inverse bridge support leg, It means the product of the number of bridge units counted backward from the opposite bank and the length of the bridge unit.

[0120] Then calculate the horizontal distance between the observation point G and each reciprocal bridge support leg:

[0121]

[0122]

[0123] In the formula, the value range of n is from 1 to N0-1. It is the horizontal distance between the observation point G and each reciprocal bridge support leg.

[0124] Please refer to Figure 2 ,according to The geometric relationship is

[0125]

[0126] Observation point G to bridge support leg The distance is:

[0127]

[0128] In the formula, the value range of n is from 1 to N0-1. is the distance between each bridge unit and the landing point of the bridge support leg, It is the angle between the straight line drawn from the landing point of each bridge support leg relative to the observation point and the horizontal line. is the distance between the landing point of each bridge support leg and the observation point, is the distance between the contact point between each bridge support leg and the single bridge section relative to the preset target point, and

[0129] S130: judging whether the bridge equipment meets the requirements for erection according to the parameter information required for the bridge erection and the bridge equipment information, and generating a judgment result.

[0130] It is understandable that the erection requirements are specifically manifested as: the maximum erection length of the bridge equipment is greater than or equal to the distance between the preset target point and the ground projection of the observation point, and the adjustment range of the bridge support leg includes the distance between each bridge unit and the landing point of the bridge support leg. In other words, the maximum erection length of the bridge equipment is greater than or equal to the distance between the preset target point and the ground projection of the observation point, which means that the bridge equipment can be erected to the other side of the gully. The adjustment range of the bridge support leg includes the distance between each bridge unit and the landing point of the bridge support leg, which means that the bridge support leg can effectively support the bridge equipment.

[0131] If the bridge equipment meets the erection requirements, it means that the current preset target point can successfully complete the bridge equipment erection. If the bridge equipment does not meet the erection requirements, it means that the current preset target point cannot successfully complete the bridge equipment erection and a new preset target point needs to be selected.

[0132] Please refer to Figure 3 The following describes the specific implementation process of judging whether the bridge equipment meets the erection requirements and generating the judgment result according to the parameter information and bridge equipment information required for the bridge erection:

[0133] Further, in a specific implementation manner provided in the present application, judging whether the bridge equipment meets the erection requirements based on the bridge erection parameter information and the bridge equipment information, and generating a judgment result specifically includes:

[0134] According to the maximum length of the bridge equipment erection and the distance of the preset target point relative to the ground projection of the observation point, it is determined whether the maximum length of the bridge equipment erection is greater than or equal to the distance of the preset target point relative to the ground projection of the observation point;

[0135] When the maximum length of the bridge equipment erection is greater than or equal to the distance between the preset target point and the ground projection of the observation point, it is determined whether the distance between each bridge unit and the landing point of the bridge support leg is within the adjustment range of the bridge support leg;

[0136] When the distance between each bridge unit and the landing point of the bridge supporting leg is within the adjustment range of the bridge supporting leg, a judgment result is generated that the bridge erection equipment meets the erection requirements.

[0137] Further, in another specific implementation manner provided in the present application, judging whether the bridge equipment meets the erection requirements according to the bridge erection parameter information and the bridge equipment information, and generating a judgment result, specifically includes:

[0138] When the maximum length of the bridge equipment erection is less than the distance of the preset target point relative to the ground projection of the observation point, a judgment result is generated that the bridge equipment does not meet the erection requirements, and an instruction is sent to reselect the preset target point position information.

[0139] Further, in another specific implementation manner provided in the present application, judging whether the bridge equipment meets the erection requirements according to the bridge erection parameter information and the bridge equipment information, and generating a judgment result, specifically includes:

[0140] When the distance between each bridge unit and the landing point of the bridge support leg is not within the adjustment range of the bridge support leg, a judgment result is generated that the bridge erection equipment does not meet the erection requirements, and an instruction to reselect the preset target point position information is sent.

[0141] S140: When the judgment result is that the bridge equipment meets the construction requirements, the position information of the bridge construction starting point relative to the preset target point is calculated based on the observation data information and the bridge equipment information.

[0142] It is understandable that the starting point of bridge erection is different from the observation point, and the position information of the starting point of bridge erection is determined based on the position information of the preset target point and the required number of bridge units and the length of the bridge units. In other words, when the judgment result is that the bridge equipment meets the erection requirements, the position information of the preset target point does not need to be changed. At this time, the total length of the bridge equipment can be calculated based on the required number of bridge units and the length of the bridge units. Then, based on the distance of the preset target point relative to the ground projection of the observation point, the difference between the total length of the bridge equipment and the distance of the preset target point relative to the ground projection of the observation point is calculated, that is, the distance of the starting point of bridge erection relative to the observation point. Combined with the actual geographical location of the observation point and the distance of the starting point of bridge erection relative to the observation point, the position information of the starting point of bridge erection relative to the preset target point can be obtained.

[0143] S150: Outputting the observation data information of the preset target point relative to the observation point and the position information of the bridge-building starting point relative to the preset target point as a bridge-building decision.

[0144] It is understandable that when the judgment result is that the bridge equipment meets the requirements for erection, the observation data information of the preset target point relative to the observation point and the position information of the bridge erection starting point relative to the preset target point can be output as the bridge erection decision. The line connecting the bridge erection starting point and the preset target point can also be used as the reference direction for bridge erection operations, and the reference direction for bridge erection operations and the observation data information of the preset target point relative to the observation point can be output.

[0145] The bridge erection auxiliary method provided in the embodiment of the present application can quickly determine whether the bridge equipment meets the erection requirements by acquiring observation data information and bridge equipment information, and generate a judgment result in combination with the bridge equipment information. According to the judgment result, it is determined whether to adjust the preset target point of the bridge erection operation. When the bridge equipment meets the erection requirements, the bridge erection decision is output, thereby improving the success rate of the bridge erection operation.

[0146] Please refer to Figure 4 To support the bridge auxiliary method, the present application also provides a bridge auxiliary system 100, including:

[0147] An acquisition module 11 is used to acquire observation data information and bridge equipment information;

[0148] The calculation module 12 is used to calculate the parameter information required for bridge erection according to the observation data information; and is also used to calculate the position information of the bridge erection starting point relative to the preset target point according to the observation data information and the bridge equipment information when the judgment result is that the bridge equipment meets the erection requirements;

[0149] A judgment module 13 is used to judge whether the bridge equipment meets the construction requirements according to the bridge construction parameter information and bridge equipment information, and generate a judgment result;

[0150] The output module 14 is used to output the observation data information of the preset target point relative to the observation point and the position information of the bridge-building starting point relative to the preset target point as a bridge-building decision.

[0151] It is understandable that the environment of bridge erection operations is relatively random, and a lot of geographic information is unknown in actual bridge erection operations. According to the specific practice of bridge erection operations, the following application provides a scenario where the geographic information of gullies needs to be surveyed: before the bridge erection operation, the width of the gully area is unknown, and the depth of the gully area is unknown. When the staff is unknown about the geographic information of the gully, it is difficult to quickly determine the starting point and the target point of the bridge erection operation. Therefore, a simple survey of the nearby geographic information is required.

[0152] Furthermore, the bridge-building auxiliary system 100 also includes a surveying instrument for measuring geographic information of a preset target point relative to the surveying instrument.

[0153] Specifically, the staff needs to select at least one point on the opposite bank of the gully as the preset target point for the bridge erection operation. The preset target point can be understood as the bridge loading point, that is, the completion point of the bridge erection operation. Usually, the preset target point can be changed according to the erection requirements.

[0154] A measuring instrument is set up near the starting point of the bridge erection operation. The measuring instrument has at least the function of distance measurement and angle measurement, and is used to measure the geographic information of the preset target point relative to the measuring instrument. When the measuring instrument is working, the measuring instrument is used as an observation point to measure the observation data information of the preset target point relative to the observation point. For example, the distance of the preset target point relative to the observation point, the angle between the straight line drawn by the preset target point relative to the observation point and the horizontal line, and the height of the observation point relative to the ground.

[0155] The acquisition module 11 is used to acquire observation data information and bridge equipment information. In other words, the acquisition module 11 at least acquires the distance between the preset target point and the observation point, the angle between the straight line between the preset target point and the observation point and the horizontal line, and the height of the observation point relative to the ground.

[0156] It is understandable that the bridge equipment information is related to the model of the bridge equipment. The bridge equipment described in this application is manifested as a mechanized bridge in a specific application scenario, such as a 69A light mechanized bridge, a GQL120A light mechanized bridge, an 84A heavy mechanized bridge, and a GQL111 heavy mechanized bridge. The mechanized bridge is composed of a plurality of bridge body units, and bridge support legs are arranged between adjacent bridge body units.

[0157] It should be noted that different types of bridge equipment have different parameters. The acquisition module 11 can at least determine bridge equipment information such as the maximum length of bridge equipment erection, bridge unit length, and adjustment range of bridge support legs according to the model of the bridge equipment.

[0158] The calculation module 12 is used to calculate the parameter information required for bridge construction according to the observation data information.

[0159] It can be understood that the parameter information required for bridge erection at least includes the distance of the preset target point relative to the ground projection of the observation point, the required number of bridge units, the required number of bridge support legs, and the distance between each bridge unit and the landing point of the bridge support leg. Among them, the required number of bridge units can be understood as the number of bridge units required to complete the bridge erection operation. The required number of bridge support legs can be understood as the number of bridge unit groups required to complete the bridge erection operation. The distance between each bridge unit and the landing point of the bridge support leg can be understood as the distance between the bridge support leg and the gully contact surface relative to the bridge unit in a single-section bridge unit.

[0160] The following describes the specific implementation process of the calculation module 12 calculating the parameter information required for bridge building according to the observed data information:

[0161] Furthermore, in a specific implementation manner provided in the present application, the calculation module 12 calculates the distance of the preset target point relative to the ground projection of the observation point, specifically including:

[0162] The calculation module 12 calculates the angle between the straight line drawn by the preset target point relative to the preset starting point and the horizontal line according to the distance between the preset target point and the observation point, the angle between the straight line drawn by the preset target point relative to the observation point and the horizontal line, and the height of the observation point relative to the ground through the following formula;

[0163]

[0164] Where h is the height of the observation point relative to the ground, GT is the distance between the preset target point and the observation point, θ1 is the angle between the straight line drawn from the preset target point to the observation point and the horizontal line, and θ2 is the angle between the straight line drawn from the preset target point to the preset starting point and the horizontal line;

[0165] The calculation module 12 calculates the distance of the preset target point relative to the ground projection of the observation point by the following formula according to the distance of the preset target point relative to the observation point, the angle between the straight line drawn by the preset target point relative to the observation point and the horizontal line, the height of the observation point relative to the ground, and the angle between the straight line drawn by the preset target point relative to the preset starting point and the horizontal line;

[0166]

[0167] Where OT is the distance between the preset target point and the ground projection of the observation point.

[0168] The derivation process of the above formula is as follows:

[0169] Given that the height of the observation point relative to the ground is GO=h, the distance of the preset target point relative to the observation point is GT, and the angle between the straight line drawn from the preset target point to the observation point and the horizontal line is θ1, then according to Figure 2 The geometric relationship given in

[0170] G1T=GT·sinθ1

[0171] GO=G1O′=h

[0172] O′T=G1T-G1O′=G1T-h

[0173] GG1=OO′=GT·cosθ1

[0174] Where GG1 is the horizontal distance between the preset target point and the observation point.

[0175] According to the trigonometric theorem, we have

[0176]

[0177]

[0178] Where h is the height of the observation point relative to the ground, GT is the distance between the preset target point and the observation point, θ1 is the angle between the straight line drawn from the preset target point to the observation point and the horizontal line, θ2 is the angle between the straight line drawn from the preset target point to the preset starting point and the horizontal line, and OT is the distance between the preset target point and the ground projection of the observation point.

[0179] Furthermore, in a specific implementation manner provided in the present application, the calculation module 12 calculates the number of bridge units and the number of bridge support legs, specifically including:

[0180] The calculation module 12 calculates the number of bridge units and the number of bridge support legs by the following formula according to the distance of the preset target point relative to the ground projection of the observation point and the length of the bridge unit;

[0181] N0=OT / P;

[0182] M = N0-1;

[0183] Where N0 is the number of bridge units, OT is the distance between the preset target point and the ground projection of the observation point, P is the length of a single bridge section, and M is the number of bridge support legs.

[0184] It should also be noted that the calculation module 12 uses the rule of rounding up to obtain the result of calculating the number of bridge units.

[0185] Further, in a specific implementation manner provided in the present application, the calculation module 12 calculates the distance between each bridge unit and the landing point of the bridge support leg, specifically including:

[0186] The calculation module 12 calculates the position information of the landing point of each bridge support leg relative to the preset target point according to the required number of bridge units and the length of the bridge unit;

[0187] The calculation module 12 measures the distance between the landing point of each bridge support leg and the observation point, and the angle between the straight line drawn by the landing point of each bridge support leg and the observation point and the horizontal line according to the position information of the landing point of each bridge support leg relative to the preset target point;

[0188] The calculation module 12 calculates the distance between each bridge unit and the landing point of the bridge support leg according to the distance between the landing point of each bridge support leg and the observation point and the angle between the straight line drawn by the landing point of each bridge support leg and the observation point and the horizontal line, and the formula is as follows:

[0189]

[0190]

[0191] In the formula, the value range of n is from 1 to N0-1. is the distance between each bridge unit and the landing point of the bridge support leg, It is the angle between the straight line drawn from the landing point of each bridge support leg relative to the observation point and the horizontal line. is the distance between the landing point of each bridge support leg and the observation point, is the distance between the contact point between each bridge support leg and the single bridge section relative to the preset target point, and

[0192] It is understandable that the ground in the gully is complicated and it is difficult for the calculation module 12 to directly calculate the distance between each bridge unit and the landing point of the bridge support leg. Therefore, before calculating the distance between each bridge unit and the landing point of the bridge support leg, the calculation module 12 needs to determine the position information of each bridge support leg landing point relative to the preset target point. Specifically, the calculation module 12 can calculate the length of each bridge unit group according to the required number of bridge units and the length of the bridge unit, that is, the horizontal distance of each bridge support leg landing point relative to the preset target point. The calculation module 12 can calculate the horizontal distance between each bridge support leg landing point and the observation point according to the horizontal distance between each bridge support leg landing point and the preset target point and the distance of the ground projection of the preset target point relative to the observation point. After that, the calculation module 12 measures the distance between each bridge support leg landing point and the observation point, and the angle between the straight line drawn by each bridge support leg landing point and the observation point and the horizontal line according to the horizontal distance between each bridge support leg landing point and the observation point through a measuring instrument. The calculation module 12 can then calculate the distance between each bridge unit and the landing point of the bridge support leg according to the trigonometric function theorem.

[0193] Specifically, the derivation process of the above formula is as follows:

[0194] Calculate the horizontal distance between the preset target point and each inverse bridge support leg in sequence:

[0195]

[0196] In the formula, the value range of n is from 1 to N0-1. is the horizontal distance between the preset target point and each inverse bridge support leg, It means the product of the number of bridge units counted backward from the opposite bank and the length of the bridge unit.

[0197] Then calculate the horizontal distance between the observation point G and each reciprocal bridge support leg:

[0198]

[0199]

[0200] In the formula, the value range of n is from 1 to N0-1. It is the horizontal distance between the observation point G and each reciprocal bridge support leg.

[0201] according to The geometric relationship is

[0202]

[0203] Observation point G to bridge support leg The distance is:

[0204]

[0205] In the formula, the value range of n is from 1 to N0-1. is the distance between each bridge unit and the landing point of the bridge support leg, It is the angle between the straight line drawn from the landing point of each bridge support leg relative to the observation point and the horizontal line. is the distance between the landing point of each bridge support leg and the observation point, is the distance between the contact point between each bridge support leg and the single bridge section relative to the preset target point, and

[0206] The judgment module 13 is used to judge whether the bridge equipment meets the construction requirements according to the parameter information required for the bridge construction and the bridge equipment information, and generate a judgment result.

[0207] It is understandable that the erection requirements are specifically manifested as: the maximum erection length of the bridge equipment is greater than or equal to the distance between the preset target point and the ground projection of the observation point, and the adjustment range of the bridge support leg includes the distance between each bridge unit and the landing point of the bridge support leg. In other words, the maximum erection length of the bridge equipment is greater than or equal to the distance between the preset target point and the ground projection of the observation point, which means that the bridge equipment can be erected to the other side of the gully. The adjustment range of the bridge support leg includes the distance between each bridge unit and the landing point of the bridge support leg, which means that the bridge support leg can effectively support the bridge equipment.

[0208] If the bridge equipment meets the erection requirements, it means that the current preset target point can successfully complete the bridge equipment erection. If the bridge equipment does not meet the erection requirements, it means that the current preset target point cannot successfully complete the bridge equipment erection and a new preset target point needs to be selected.

[0209] The following describes the specific implementation process of the judgment module 13 judging whether the bridge equipment meets the erection requirements and generating the judgment result according to the required bridge erection parameter information and bridge equipment information:

[0210] Further, in a specific implementation manner provided in the present application, the judgment module 13 judges whether the bridge equipment meets the erection requirements according to the bridge erection parameter information and the bridge equipment information, and generates a judgment result, which specifically includes:

[0211] The judging module 13 judges whether the maximum length of the bridge equipment erection is greater than or equal to the distance of the preset target point relative to the ground projection of the observation point according to the maximum length of the bridge equipment erection and the distance of the preset target point relative to the ground projection of the observation point;

[0212] When the bridge equipment erection limit length is greater than or equal to the distance of the preset target point relative to the ground projection of the observation point, the judgment module 13 judges whether the distance between each bridge unit and the landing point of the bridge support leg is within the adjustment range of the bridge support leg;

[0213] When the distance between each bridge unit and the landing point of the bridge support leg is within the adjustment range of the bridge support leg, the judgment module 13 generates a judgment result that the bridge erection equipment meets the erection requirements.

[0214] Further, in another specific implementation manner provided in the present application, the judgment module 13 judges whether the bridge equipment meets the erection requirements according to the bridge erection parameter information and the bridge equipment information, and generates a judgment result, which specifically also includes:

[0215] When the maximum length of the bridge equipment erection is less than the distance of the preset target point relative to the ground projection of the observation point, the judgment module 13 generates a judgment result that the bridge equipment does not meet the erection requirements, and sends an instruction to reselect the preset target point position information.

[0216] Further, in another specific implementation manner provided in the present application, the judgment module 13 judges whether the bridge equipment meets the erection requirements according to the bridge erection parameter information and the bridge equipment information, and generates a judgment result, which specifically also includes:

[0217] When the distance between each bridge unit and the landing point of the bridge support leg is not within the adjustment range of the bridge support leg, the judgment module 13 generates a judgment result that the bridge erection equipment does not meet the erection requirements, and sends an instruction to reselect the preset target point position information.

[0218] When the judgment result is that the bridge equipment meets the construction requirements, the calculation module 12 calculates the position information of the bridge construction starting point relative to the preset target point based on the observation data information and the bridge equipment information.

[0219] It is understandable that the starting point of bridge erection is different from the observation point, and the position information of the starting point of bridge erection is determined based on the position information of the preset target point and the required number of bridge units and the length of the bridge units. In other words, when the judgment result is that the bridge equipment meets the erection requirements, the position information of the preset target point does not need to be changed. At this time, the calculation module 12 can calculate the total length of the bridge equipment based on the required number of bridge units and the length of the bridge units. The calculation module 12 then calculates the difference between the total length of the bridge equipment and the ground projection distance of the preset target point relative to the observation point, that is, the distance of the starting point of bridge erection relative to the observation point, based on the distance of the preset target point relative to the ground projection of the observation point. The calculation module 12 combines the actual geographical location of the observation point and the distance of the starting point of bridge erection relative to the observation point to obtain the position information of the starting point of bridge erection relative to the preset target point.

[0220] When the judgment result is that the bridge equipment meets the requirements for erection, the output module 14 can output the observation data information of the preset target point relative to the observation point and the position information of the bridge erection starting point relative to the preset target point as a bridge erection decision. The output module 14 can also use the line connecting the bridge erection starting point and the preset target point as the reference direction for bridge erection operations, and output the reference direction for bridge erection operations and the observation data information of the preset target point relative to the observation point.

[0221] The bridge erection auxiliary system 100 provided in the embodiment of the present application can quickly determine whether the bridge equipment meets the erection requirements by acquiring observation data information and bridge equipment information, and generate a judgment result in combination with the bridge equipment information. According to the judgment result, it is determined whether to adjust the preset target point of the bridge erection operation. When the bridge equipment meets the erection requirements, the bridge erection decision is output, thereby improving the success rate of the bridge erection operation.
