Background

In recent years, with rapid development of Railway wireless communication technology, Railway communication towers of GSM-R (Global System for Mobile Communications-railways) are increasingly used for Railway communication. However, factors such as crustal movement, severe weather, aging and oxidation, potential artificial theft and damage and the like can bring certain potential safety hazards to the railway communication iron tower, and even the railway communication iron tower inclines and collapses.

If the communication tower state is detected by depending on regular inspection and artificial observation of special personnel, the labor cost is increased, certain subjectivity exists, and manual actual measurement of certain parameters is difficult.

The railway communication iron tower is not an integral rigid structure, but is formed by combining a plurality of sections, and each section is fixed by bolts. Due to the influence of strong wind or geographical positions, the conditions that one section is left and the other section is right may occur, so that the inclination angle of the tower top cannot truly reflect the whole inclination state of the railway communication iron tower. In the related art, an angle sensor is mounted on the top of a railway communication tower, and the inclination angle of the top of the tower cannot truly reflect the overall inclination state of the railway communication tower, so that the state of the railway communication tower is detected by calculating a trigonometric function of the inclination angle of the top of the tower, the obtained detection result is inaccurate, and the difference from the actual situation is large.

In order to solve the above problem, in the embodiment of the present disclosure, a railway communication tower is taken as an example for description, but a person skilled in the art may know that any type of tower is within the protection scope of the embodiment of the present disclosure, for example, a power transmission tower, a telecommunication tower, and the like.

As shown in fig. 1, the iron tower state detection method includes the following steps:

and 11, determining a first position of the tower top of the iron tower to be detected and a second position which is far away from the iron tower to be detected by a preset horizontal distance on the ground.

Fig. 2 is a schematic diagram of a railway communication iron tower provided in an embodiment of the present disclosure in an inclined state, and referring to fig. 2, a first position a is a tower top position of an iron tower to be measured, and generally refers to a position of the iron tower closest to a tower top. Illustratively, if the railway communication tower has 10 sections, each of which is about 5 meters in height, the first position a refers to the 9 th section from the tower footing. The second position B is a position on the ground that is a preset distance d from the tower footing of the iron tower to be measured, the preset distance d is OB, where O is the center position of the railway communication iron tower, and OA is the continuity between the center position of the railway communication iron tower and the tower top, as can be seen from fig. 2, OA is an oblique line, which indicates that the railway communication iron tower is in an oblique state at this time.

In this step, the first position a and the second position B may be represented by three-dimensional coordinates, illustratively, the first position a is represented by (x)_a，y_a，z_a) And the second position B is represented by (x)_b，y_b，z_b）。

A horizontal displacement between the first position and the second position is determined, step 12.

In this step, a horizontal displacement D1 between the first position a and the second position B is calculated according to the x coordinate and the y coordinate in the three-dimensional coordinate, and it should be noted that, as shown in fig. 2, if the iron tower to be measured is in a vertical state, D1= D; and D1< D if the iron tower to be tested is in an inclined state.

And step 13, determining the state of the iron tower to be detected according to the horizontal displacement and the reference horizontal displacement.

In this step, a difference between the reference horizontal displacement and the horizontal displacement calculated in step 12 is calculated, and the state of the iron tower to be measured is determined according to the difference.

The method for detecting the state of the iron tower comprises the following steps: determining a first position A of the tower top of the iron tower to be detected and a second position B which is far away from the iron tower to be detected on the ground by a preset horizontal distance, determining a horizontal displacement D1 between the first position A and the second position B, and determining the state of the iron tower to be detected according to the horizontal displacement D1 and a reference horizontal displacement; according to the method and the device, whether the iron tower has the risk of inclination or not is detected according to the horizontal displacement of the tower top of the iron tower to be detected, the detection result is closer to the actual condition, and the accuracy is high; moreover, the labor cost is not increased, and the scheme is easy to realize.

In some embodiments, the determining a first position of the tower top of the tower to be tested and a second position on the ground away from the tower to be tested by a preset horizontal distance (i.e., step 11) includes the following steps: a first position a and a second position B are determined according to a satellite positioning algorithm. The embodiment of the disclosure utilizes a satellite positioning system to realize accurate positioning by means of a receiver and four satellites.

In some embodiments, the satellite positioning system may be a Beidou satellite navigation system, a Galileo satellite navigation system, a Russian global navigation satellite system, or the like.

The satellite positioning algorithm comprises a satellite static positioning algorithm and a satellite dynamic positioning algorithm, wherein in the satellite static positioning algorithm, the position of the receiver is fixed and unchanged in the process of capturing and tracking the satellite, the receiver can measure the propagation time of signals with high precision, and the three-dimensional coordinate of the position of the antenna of the receiver is calculated by utilizing the known position of the satellite in orbit. In the satellite dynamic positioning algorithm, a receiver is used for measuring the running track of a moving object, and the moving object carrying the receiver is called a carrier (such as a sailing ship, an aerial airplane, a traveling vehicle and the like). The receiver antenna on the carrier moves relative to the earth during the process of tracking the satellite, and the receiver detects the state parameters (namely the instantaneous three-dimensional position and the three-dimensional speed) of the moving carrier in real time by means of signals between the receiver antenna and the satellite. The satellite dynamic positioning algorithm has high speed, can obtain real-time data, but has poor precision which is generally 30 mm; the satellite static positioning algorithm has high precision, the horizontal precision can reach 2.5mm, but the calculation time is long and is about 30 minutes.

In the embodiment of the disclosure, in order to calculate the relatively real state of the railway communication tower, a satellite static positioning algorithm is adopted to determine the first position a and the second position B. Correspondingly, 2 receivers are arranged, wherein the first receiver 1 is located at the top of the iron tower to be tested, and the second receiver 2 is located on the ground away from the iron tower to be tested by a preset horizontal distance, that is, the position of the first receiver 1 is a first position a, determining the first position a is determining the position of the first receiver 1, the position of the second receiver 2 is a second position B, and determining the second position B is determining the position of the second receiver 2.

The principle of the satellite static positioning algorithm is described below with reference to fig. 3.

As shown in FIG. 3, assume that 3 satellites A, B and C, respectively, the receiver K receives electromagnetic wave signals transmitted from three satellites (A, B, C) at intervals, the signals include information about the position of each satellite, and the receiver K assumes satellite ASatellite BSatellite C. The receiver K records the time it takes for the receiving satellite A, B, C to transmit the electromagnetic wave signal and extracts from the signal the position coordinates of each satellite, assuming that the time it takes the receiver K to receive the satellites a, B, C is a, B, C, respectively, then the receiver K can resolve the following system of equationsObtaining own position information:

wherein (z, y, z) is the position coordinate of the receiver K,is the speed of light.

Because the time of the 3 satellites A, B and C is not uniform with the time of the receiver K, the position obtained by the receiver K through the equation system is greatly deviated from the actual position, and the time difference between the 3 satellites A, B and C and the receiver K is assumed to beThen the above system of equations changes as follows:

from the above equation system, it can be known that even if the time is not calibrated, if the time difference between each satellite and the receiver K is known in advance, the time taken to receive the electromagnetic wave signal of each satellite can be correctedAnd (3) removing the solvent. However, it is difficult to accurately calculate the time difference between the receiver K and the 3 satellites, and once the time difference has a small error, the error is amplified after multiplying by the speed of light. Therefore, a satellite D (not shown) is introduced, the position information of which is. Suppose the time differences between the 4 satellites A, B, C, D and the clock source are. The time difference between the receiver K and the clock source is. Then the time difference between receiver K and 4 satellites is:assuming that the receiver K takes a, B, C, D to receive the satellites a, B, C, D, respectively, then further, the above equation system can be transformed as follows:

the receiver K can calculate its own position by resolving this final transformed set of equations.

In order to solve the problem of poor timeliness in manual inspection, in some embodiments, the determining a first position of the tower top of the tower to be tested and a second position on the ground far away from the tower to be tested by a preset horizontal distance (i.e., step 11) includes the following steps: and periodically determining a first position of the tower top of the iron tower to be detected and a second position of the ground far away from the iron tower to be detected by a preset horizontal distance. Accordingly, the reference horizontal displacement is a horizontal displacement between the first position a and the second position B of the previous cycle. That is to say, in the embodiment of the present disclosure, the state of the railway communication tower is periodically detected, and the current state of the railway communication tower is detected according to the horizontal displacement between the first position a and the second position B calculated in the current period and the horizontal displacement between the first position a and the second position B calculated in the previous period, and specifically, the current state of the railway communication tower is determined according to the difference between the horizontal displacement in the current period and the horizontal displacement in the previous period.

In some embodiments, the determining the state of the tower to be tested according to the horizontal displacement and the reference horizontal displacement (i.e. step 13) includes the following steps: determining the inclination of the iron tower to be detected in response to the fact that the difference value between the horizontal displacement and the reference horizontal displacement is larger than a preset threshold value; and determining that the state of the iron tower to be detected is normal in response to the fact that the difference value between the horizontal displacement and the reference horizontal displacement is smaller than or equal to a preset threshold value. That is, if the difference between the horizontal displacement between the first position a and the second position B in the current period and the horizontal displacement between the first position a and the second position B in the previous period is large, it indicates that the railway communication tower is inclined; and if the difference between the horizontal displacement between the first position A and the second position B in the current period and the horizontal displacement between the first position A and the second position B in the previous period is smaller, the state of the railway communication iron tower is normal. By reasonably setting the length of the period, the state of the railway communication iron tower can be detected in real time, and potential safety hazards can be found in time.

In some embodiments, the period may be set to 30 seconds or 1 minute.

In some embodiments, the predetermined horizontal distance may be 5-20 meters.

In order to deal with the safety hazard in time, in some embodiments, after determining the state of the iron tower to be tested according to the horizontal displacement and the reference horizontal displacement (i.e., step 13), the iron tower state detection method may further include the following steps: and responding to the inclination of the iron tower to be measured determined according to the horizontal displacement and the reference horizontal displacement, and giving an alarm.

In order to eliminate potential safety hazards of a railway communication iron tower and avoid occurrence of events endangering driving safety such as inclination and collapse, the embodiment of the disclosure provides an iron tower state detection method. Because the receiver installed on the ground is stable and cannot move, the swing distance of the railway communication iron tower can be reflected by the difference value between the horizontal displacement of the current period and the horizontal displacement of the previous period, so that the state of the railway communication iron tower is determined, the state of the railway communication iron tower can be directly, accurately and truly reflected by the horizontal displacement, and the detection result is more accurate. According to the embodiment of the disclosure, the state of the railway communication iron tower is detected through a satellite positioning algorithm, and basic reference data can be provided for centralized renovation, intermediate overhaul and overhaul of the railway communication iron tower.

The second receiver 2 is arranged on the ground away from the iron tower 3 to be detected by a preset horizontal distance d and is used for determining the second position according to a satellite static positioning algorithm.
