Background
In the world of the electric railway operation mileage and operation speed of China, a large number of independent intellectual property new technologies and new equipment are continuously put into railway operation, so that the railway technology management of China is in the leading position in the world.
In order to prevent the occurrence of pantograph-catenary faults and realize safe and high-quality power supply in the daily management of electrified railways, a railway engineering and power supply department always surrounds a most important bottom line, namely a railway standard line. The standard railway line is also called as red line and is marked on the inner edge of a contact net support or the side wall of a tunnel, a bridge or a platform to represent the red transverse line of the standard height of the top surface of the steel rail in operation. The elevation of the red line is a rail surface standard line designed by a contact network, each parameter marked by the red line is a safety basis for determining the height of a steel rail and a contact network lead, the relative positions of the steel rail and a bridge, a tunnel side wall and the side surface of a contact network strut, the marked red line can be confirmed together with a power supply department and a work department when the railway is put into operation, and a large amount of manpower and material resources are input by the power supply department every year to recheck and mark the rail surface red line, and then the rail surface red line is confirmed by the work department.
At present, the measurement marking of the rail surface red line is carried out in two ways at home and abroad, the first way is the traditional way, namely, a horizontal T-square is utilized, one side of the T-square is put on a steel rail, the other side of the T-square leans against a pillar, the side limit distance can be measured, the position of the red line can be measured through up-down horizontal adjustment, when a curve is met, the T-square is put on a high rail to be leveled, the distance between the T-square and the low rail is measured (also called superelevation), and then the superelevation 1/2 position extends to the horizontal position of the pillar to determine the position of the red line. The disadvantage is that the measuring staff can complete the work by at least two people and 3 people who mark the red line. Secondly, the process is complex and the time consumption is too long, and the process can be completed by adding calculation besides measuring two groups of data. The second mode is that a professional laser measuring instrument is used for measuring each support and placing the measuring instrument on two steel rails, the measuring instrument emits laser to the support, the measuring instrument intelligently obtains ultrahigh and lateral limit data, and red lines are marked. The problem is that the measuring instrument weight is large, the weight of one set of measuring instrument 15KG, and measurement personnel need hold the measuring instrument and squat to the pillar and measure moreover, consume physical power seriously, and every measurement personnel just has reached the physical power limit basically after measuring 100 data and just can't measure again.

Example 2
The embodiment provides a method for intelligently measuring a marked trolley by using the rail surface standard line, which comprises the following steps:
starting a power supply system, controlling the electric driving wheels 2 to start through a control system, and enabling the trolley main body 1 to run along the railway steel rails 100 on two sides; the horizontal control module continuously detects whether the trolley main body 1 is in a horizontal state, when the horizontal control module detects that the trolley main body 1 is in a non-horizontal state, an action control signal is sent to the electric push rod 6 to control the extension or shortening of the telescopic rod of the electric push rod 6, so that the wheel 4 at the bottom of the other side of the trolley main body connected with the electric push rod is driven to extend or contract until the horizontal control module detects that the trolley main body 1 returns to the horizontal state again, a stop control signal is sent to the electric push rod 6, and the electric push rod 6 stops acting; the wheel 4 drives the ultrahigh scale rod 7 to move together in the moving process, and after the wheel 4 stops moving, the absolute value of the difference between the scale pointed by the ultrahigh pointer 8 and the initial scale pointed by the ultrahigh pointer 8 is the current ultrahigh value (in this embodiment, the scale value pointed by the ultrahigh pointer 8 at the current time is the ultrahigh value).
When the trolley main body 1 runs beside a support, the laser range finder 9 is controlled to be started through the control system, a laser beam emitted by the laser range finder 9 penetrates through a space 5 between two wheels 2 and 3 at the bottom of one side of the trolley main body 1 and is projected on the side face of the support to form a marked red line, the laser range finder 9 transmits a measured numerical value to the control system, and the control system transmits the numerical value to the display 10 for display; the numerical value measured by the laser range finder 9 is the side limit, and the difference value between the scale value of the ultrahigh scale rod pointed by the ultrahigh pointer 8 at the current position and the scale value of the ultrahigh scale rod pointed by the trolley body 1 at the initial height state is the ultrahigh value of the railway rails 100 at two sides. The rail face gauge line position is determined by extending to the post level at ultra-high 1/2, according to railroad specifications. And recording the current ultrahigh value as D, if the telescopic rod of the current electric push rod is in an extension state, the height obtained by subtracting D/2 from the position of the marked red line on the support is the position of the rail surface standard line, and if the telescopic rod of the current electric push rod is in a contraction state, the height obtained by adding D/2 to the position of the marked red line on the support is the position of the rail surface standard line.
In this embodiment, when the scale indicated by the super high pointer is a numerical value below the scale 0, the height obtained by adding D/2 to the position of the red mark on the support is the position of the rail surface standard line, and when the scale indicated by the super high pointer is a numerical value above the scale 0, the height obtained by subtracting D/2 from the position of the red mark on the support is the position of the rail surface standard line.
For example, when one rail rises by 100mm, the electric push rod 6 on the other rail automatically extends by 100mm to adjust the trolley body to a horizontal state, and at the moment, the ultrahigh pointer 8 points to a position of 100m above the scale 0, and the ultrahigh value is 100 mm.

On the contrary, if the steel rail on the other side is lifted by 100mm, the electric push rod 6 automatically contracts by 100mm so as to adjust the trolley body to a horizontal state, at this time, the ultrahigh pointer 8 points to a position 100m below the scale 0, the ultrahigh value is 100mm, at this time, the position of the laser beam projected to the support column by the laser range finder 9 in the middle of the trolley body is projected on the support column position according to the low steel rail, 100mm 2 is calculated to be 50mm, and then the position of the laser beam on the support column, namely the position of the marked red line, plus the height of 50mm is the position of the rail surface standard line.
