Description

Technical Field

[0001] The present invention belongs to the technical field of rail transit, and particularly relates to a method, a system, an electronic device and a medium for health assessment of a turnout and a conversion device. Background Art

[0002] The turnout conversion system is used to convert and lock the turnout and supervise and inspect the position information of the turnout. The turnout conversion system is a key facility to ensure train operation safety and improve transportation efficiency. However, due to its strong equipment correlation, complex interfaces, and harsh equipment application environment, the equipment maintenance workload is large and the failure risk is high. The failure rate and maintenance workload of the turnout and the conversion device account for a relatively high proportion in railway track maintenance and signal maintenance. With the continuous development of railway construction, the maintenance of existing turnouts and conversion devices is difficult to meet the requirements of future railways with higher speeds and higher efficiency. It is necessary to conduct intelligent monitoring on turnouts and conversion devices to reduce equipment failure risks, reduce maintenance workload, and improve the efficiency and benefits of railway operation and maintenance, which has important practical significance.

[0003] Currently, in the field of intelligent monitoring of turnout equipment, there are many studies on fault diagnosis of turnouts and conversion devices, but few methods for assessing the health status of turnouts. Existing assessment methods are generally based on the way of track maintenance measurement, lacking a convenient and intelligent solution.

[0004] For example, nine current state items for assessing the health status of turnouts can be determined according to the structural characteristics and usage characteristics of turnouts, mainly including turnout static geometric dimensions, rail component wear, track and signal interface, turnout status, etc. Scoring rules for each item are formulated, and the health status of the turnout is comprehensively evaluated by calculating the turnout health assessment index. However, the state items used in this solution still rely on manual measurement and evaluation, which will incur certain maintenance costs and human errors, resulting in poor accuracy and efficiency in assessing the health status of turnouts.

Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0104] First, in combination with Figure 1 , a health assessment method for a turnout and conversion equipment provided by an embodiment of the present invention will be described in detail.

[0105] Figure 1 Schematic flow diagram of a health assessment method for a turnout and conversion equipment provided by an embodiment of the present invention. This method is applicable to the following health assessment system for a turnout and conversion equipment. As Figure 1 shown, this method includes:

[0106] S101, obtaining monitoring data of a plurality of sensors under the operating state of the turnout equipment.

[0107] Specifically, the monitoring data of a plurality of sensors under the operating state of the turnout equipment can be uploaded by using the wired or wireless communication between the plurality of sensors and the health assessment system for the turnout and conversion equipment.

[0136] If the conversion resistance f satisfies f<xF, then the twelfth score is deducted;

[0137] Wherein, F is the rated conversion resistance, x is a multiple of the rated conversion resistance, and 0.8≤x≤1.8.

[0138] For example, assuming x = 1.5 and the rated conversion force is 2.5 kN, if the conversion resistance is greater than 3.75 kN, then 15 points are deducted; if the conversion resistance is greater than 2.5 kN and less than 3.75 kN, then 10 points are deducted.

[0139] Optionally, the friction conversion force of the switch machine is negatively correlated with the health index of the turnout;

[0140] The point deduction rules include:

[0141] If the friction conversion force of the switch machine is greater than or equal to the conversion force threshold, then the thirteenth score is deducted.

[0142] Taking the electric switch machine as an example, if the friction conversion force of the switch machine is greater than 10 kN, 15 points are deducted.

[0143] Optionally, the point deduction rules include:

[0144] If the friction current of the switch machine is greater than or equal to the current threshold, then the fourteenth score is deducted.

[0145] Taking the electric switch machine as an example, if the friction current is greater than 5 A, 15 points are deducted.

[0146] Optionally, the point deduction rules include:

[0147] If the temperature inside the switch machine is greater than or equal to the first temperature threshold or less than or equal to the second temperature threshold, the fifteenth score is deducted, and the first temperature threshold is greater than the second temperature threshold.

[0148] Taking the electric switch machine as an example, if the temperature inside the switch machine is higher than 70 °C or lower than -40 °C, 2 points are deducted.

[0149] Optionally, the deduction rules include:

[0150] If the humidity inside the switch machine is greater than or equal to the humidity threshold, the sixteenth score is deducted.

[0151] Taking the electric switch machine as an example, if the humidity inside the switch machine is greater than or equal to 90% (25 °C), 2 points are deducted.

[0152] Optionally, the deduction rules include: If the gap value g satisfies 0 < g ≤ t or a - t < g ≤ a, the seventeenth score is deducted, where t is the gap threshold and a is the maximum value of the gap value.

[0153] For example, if a = 4 mm and t = 1 mm, when the gap value satisfies 0 < g ≤ 1 or 3 < g ≤ 4, 2 points are deducted.

[0154] It should be noted that the operation of deducting scores according to the above deduction rules can be carried out separately for each traction point of the turnout. After completing the deduction operation for all deduction rules of a certain traction point, the health score of this traction point can be obtained. Then, according to the health scores of each traction point of the turnout, the overall health score of the turnout can be obtained, that is, the health index of the turnout can be obtained.

[0155] Optionally, the health index HI of the turnout satisfies:

[0156] HI = ω1 × S m1 +…+ ω i × S mi +…+ ω N × S mN

[0157] where S mi is the health score of the i-th traction point in the turnout, ω i is the weight of the health score of the i-th traction point in the turnout, N is the number of traction points in the turnout, and 1 ≤ i ≤ N.

[0158] S104, perform hierarchical early warning on turnouts in different health states according to the health index.

[0159] Specifically, if the health index of the turnout is greater than or equal to the health threshold, it is determined that the turnout state is healthy;

[0160] If the health index of the switch is less than the health threshold and greater than or equal to the warning threshold, the switch status is determined to be a low risk;

[0161] If the health index of the switch is less than the warning threshold and greater than or equal to the alarm threshold, the switch status is determined to be a medium risk, and the warning module is activated;

[0162] If the health index of the switch is less than the alarm threshold, the switch status is determined to be a high risk, and the alarm module is activated.

[0163] In this way, switches with different risk levels can be processed separately. For example, high-risk switches can be replaced, the monitoring intensity of medium-risk switches can be increased, the monitoring intensity of low-risk switches can be reduced, and the monitoring period of switches in good health can be increased, etc., so as to improve the efficiency and quality of switch monitoring.

[0164] Based on the health assessment method of the switch and the conversion equipment provided by the present invention, various sensor monitoring data can be automatically obtained, such as the ultimate deviation of the tip rail stroke at the traction point, the ultimate deviation of the first traction point stroke of the movable point frog, the ultimate deviation of the difference in locking amounts on both sides of the external locking device, the notch value, the conversion resistance, the friction conversion force of the switch machine, the friction current of the switch machine, the temperature inside the switch machine, or the humidity inside the switch machine. Then, the monitoring indicators are determined according to the obtained various sensor data, and the health index of the switch is comprehensively obtained according to the deduction rules corresponding to the monitoring indicators. And according to the value of the health index, hierarchical warning is carried out, which can avoid the problems of slow speed and large error in the existing switch health status assessment relying on manual measurement, thereby effectively improving the accuracy and efficiency of assessing the switch status.
