The corresponding image expression can be determined according to the relation diagram of speed and time, and then the integral is calculated, so that the function expression of the position and the time can be obtained, and further the relation diagram of the position and the time can be obtained. Fig. 4d is a graph of position versus time provided in the present application, and as shown in fig. 4d, the ice-melting vehicle is traveling at 0-4 minutes with uniform acceleration, and at 4 th minutes to 2 km; and the vehicle runs at a constant speed within 4-16 minutes and runs to 14km at 16 th minute.

Since the level signal is a low level signal when ice coating is present under the brushes, the position corresponding to the low level signal in the map of the level signal and the position is determined as the contact rail ice coating position.
After the ice melting vehicle obtains the ice coating position of the contact rail, the ice coating position of the contact rail can be sent to the terminal equipment of the user so as to be convenient for the user to check. The ice melting vehicle can also precisely melt ice according to the ice coating position of the contact rail.
According to the contact rail icing position detection method provided by the embodiment, the ice melting vehicle monitors the running speed through the speed sensor, monitors the level signal of the digital quantity input port of the industrial control computer through the icing state detection equipment, and further determines the contact rail icing position through the monitored running speed and the monitored level signal. Compared with the prior art, the ice-covering position of the contact rail is determined by monitoring the running speed and the level signal in a manual mode, and the ice-melting vehicle runs through the contact rail, so that the ice-covering position can be obtained, and the detection efficiency is effectively improved.
Fig. 5 is a schematic flow chart of a second embodiment of a method for detecting an icing position of a contact rail, which is provided in the present application, and on the basis of the foregoing embodiment, the embodiment of the present application describes a case where an ice-melting vehicle can also determine an icing state of the contact rail. As shown in fig. 5, the method for detecting the icing position of the contact rail specifically includes the following steps:
s501: and determining the duration duty ratio of the high-level signal according to the relation diagram of the level signal and time.
In this step, after the ice melting vehicle obtains a relationship diagram of the level signal and time, in order to obtain the icing state of the contact rail, it is necessary to determine the duration duty ratio of the high level signal.
For example, on the basis of fig. 4c, 0-4min and 8-16min are available as high level signals, the duration of the high level signals is 12 min, and the total duration is 16min, so the duration of the high level signals is 12/16=0.75.
It should be noted that, the above examples are only examples of the process of calculating the duration duty ratio of the high level signal, and the embodiments of the present application do not limit the period in which the high level signal is located, the duration of the high level signal, and the total duration, and may be determined according to practical situations.
S502: and determining the icing state of the contact rail according to the duration ratio.
In the step, after the ice melting vehicle obtains the duration duty ratio, the ice coating state of the contact rail can be determined according to the duration duty ratio.
If the time length duty ratio is 1, indicating that the level signals monitored in the total time length are all high level signals, and determining that the icing state is ice-free if the contact rail is not icing.
If the time length duty ratio is 0, indicating that the level signals monitored in the total time length are all low level signals, and the whole process of icing on the contact rail, determining that the icing state is complete icing.
If the time length duty ratio is more than 0 and less than 1, indicating that the level signal types monitored in the total time length are low-level signals and high-level signals, and if ice coating exists in some places on the contact rail and ice coating exists in some places, determining that the ice coating state is interval ice coating.
According to the contact rail icing position detection method, the icing state of the contact rail is determined through the duration duty ratio of the high-level signal, and the accuracy of detecting the icing state of the contact rail is effectively improved.
Fig. 6 is a schematic flow chart of a third embodiment of a contact rail icing position detection method provided by the present application, where on the basis of the foregoing embodiment, the present application describes a situation of ice melting when a low-level signal is detected after an ice melting vehicle starts running from a starting point of a running line. As shown in fig. 6, the method for detecting the icing position of the contact rail specifically includes the following steps:
s601: and when the level signal is detected to be a low level signal, determining the current starting point moment.
In the step, after the ice melting vehicle starts running from the starting point of the running line, the level signal of the digital input port of the industrial control computer is monitored, when the level signal is monitored to be a low level signal, the existence of ice coating under the electric brush is indicated, the ice melting is needed, and the current starting point moment is determined first.
S602: and calculating the driving distance of the ice melting vehicle at the position of the starting point in real time.
In this step, since there is a distance between the brush and the ice-melting coil, if the level signal is detected to be a low level signal, the ice-melting coil is controlled to operate, and the ice-melting coil does not reach the ice-covering position at this time, energy is wasted, so that the ice-melting coil needs to be controlled to operate when the ice-melting coil reaches the ice-covering position. In order to determine when the ice-melting coil reaches the ice-covering position, the driving distance of the ice-melting vehicle from the position at the starting point is required to be calculated in real time.
The running speed can be obtained through the speed sensor, and the running distance can be obtained by combining the running time.
S603: when the driving distance reaches the preset ice melting distance, controlling the ice melting coil on the same side with the first electric brush in the ice coating state detection equipment in the working state to work.
In the step, the ice melting vehicle calculates the driving distance in real time, and when the driving distance reaches the preset ice melting distance, the ice melting coil is indicated to reach the ice covering position, and the ice melting coil on the same side with the first electric brush in the ice covering state detection equipment in the working state is controlled to work for melting ice.
It should be noted that, the preset ice melting distance is the distance between the brush closest to the ice melting coil and may be 1 meter, 2 meters, 5 meters, etc., and the preset ice melting distance is not limited in the embodiment of the present application, and may be determined according to actual situations.
According to the contact rail ice coating position detection method, by means of ice melting when the low-level signal and the ice melting coil reach the ice melting position are monitored, energy sources can be effectively saved, ice melting can be achieved in the process of detecting the contact rail ice coating position, and ice melting efficiency is effectively improved.
