[0039] Figure 3 This is a schematic diagram of the structure of the electronic device provided by the present invention. Detailed Implementation

[0040] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0041] The terms "first" and "second" in the specification and claims of this invention may explicitly or implicitly include one or more of those features. In the description of the invention, unless otherwise stated, "a plurality of" means two or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0042] Traditional fault diagnosis methods rely primarily on manual inspection and maintenance, which is not only inefficient but also prone to missed detections or misdiagnoses. Furthermore, they require high-precision data acquisition and large-scale data input, placing high demands on server hardware performance. On-site debugging by personnel is necessary, making the process complex and requiring significant upfront time investment. In addition, different types of turnout equipment cannot be judged using a uniform standard and require differentiated treatment.

[0043] Based on this, this embodiment of the invention provides a fault diagnosis method for turnout equipment based on turnout relay circuit, so as to realize real-time monitoring and automatic fault diagnosis of turnout equipment, which is of great significance for improving the operational safety and reliability of turnout equipment.

[0044] Figure 1 This is a flowchart illustrating a fault diagnosis method for turnout equipment provided in an embodiment of the present invention, as shown below. Figure 1 As shown, the method includes:

[0045] S1, collects the timing signal of the turnout relay circuit of the turnout equipment;

[0046] S2, perform feature extraction on the timing signal to determine the first state of the fixed operation relay and the reverse table relay when the locking relay of the turnout equipment is activated, and the second state of other turnout relays within the corresponding delay time.

[0047] S3. Based on the first state, or based on the first state and the second state, match with a preset fault mode to determine the target fault information of the turnout equipment. The preset fault mode is used to characterize the correspondence between the state of the fixed operation relay when the locking relay of the turnout equipment is activated and the states of other turnout relays within the corresponding delay time and the fault information.

[0048] Specifically, the turnout equipment fault diagnosis method provided in this embodiment of the invention is executed by a turnout equipment fault diagnosis device. This device, as a data processing center, can be configured in an on-board host or a third-party device. The third-party device can be a local computer or a cloud computer. The local computer can be a computer, tablet, etc., without specific limitations here.

[0049] First, step S1 is executed, which involves acquiring the timing signals of the turnout relay circuit of the turnout equipment using a timing signal acquisition device installed on the turnout equipment. The turnout relay circuit may include locking relays (SJ), fixed-operation relays (DCJ), reverse-indicator relays (FBJ), reverse-operation relays (FCJ), first turnout start relays (1DQJ), first turnout start repeater relays (1DQJF), position indicator relays (DBJ), second turnout start relays (2DQJ), and protection relays (BHJ), etc. Each relay corresponds to a timing signal, which indicates whether the corresponding relay is activated.

[0050] Then, step S2 is executed to extract features from the timing signal, obtaining its waveform, frequency, phase, and other characteristics. Based on these features, the first state of the turnout equipment's locking relay when it is activated, the first state of the fixed-operation relay and the reverse-operation relay, as well as the second state of other turnout relays within the corresponding delay time, are determined. Here, "other turnout relays" refers to relays other than the locking relay and the fixed-operation relay, such as the fixed-operation relay (DCJ), the reverse-operation relay (FBJ), the reverse-operation relay (FCJ), the first turnout start relay (1DQJ), the first turnout start repeater relay (1DQJF), the position indicator relay (DBJ), the second turnout start relay (2DQJ), and the protection relay (BHJ). The first state can include activated and not activated, and the second state can include activated, not activated, whether there is voltage in each coil, and whether there is a voltage rise in each coil.

[0051] Finally, step S3 is executed, which matches the first state with a preset fault mode to determine the target fault information of the turnout equipment. Alternatively, the first state and the second state can be used to determine the target fault information of the turnout equipment. This target fault information may include whether a fault exists, the type of fault, and its location.

[0052] This preset fault mode can be used to characterize the state of the fixed operation relay when the locking relay of the turnout equipment is activated, as well as the correspondence between the state of other turnout relays and fault information within the corresponding delay time.

[0053] In the preset fault modes, the fault information involved may include abnormal excitation of the fixed operation relay, abnormal excitation of the reverse operation relay, fault of coil 3-4 or excitation circuit of the fixed operation first turnout starting relay, fault of coil 3-4 or excitation circuit of the reverse operation first turnout starting relay, fault of excitation circuit of all coils of the fixed operation first turnout starting relay, fault of excitation circuit of all coils of the reverse operation first turnout starting relay, fault of the fixed operation first turnout starting repeater relay, fault of the reverse operation first turnout starting repeater relay, fault of the fixed operation second turnout starting relay, fault of the reverse operation second turnout starting relay, fault of the fixed operation protection relay, and fault of the reverse operation protection relay, etc.

[0054] The preset fault modes can be represented by Table 1 below.

[0059] In Table 1, the delay time corresponding to the first turnout starting relay (1DQJ) is 0.15s, the delay time corresponding to the first turnout starting repeater relay (1DQJF) is 0.3s, the delay time corresponding to the second turnout starting relay (2DQJ) is 0.45s, the delay time corresponding to the protection relay (BHJ) is 0.6s, and 1s is the target delay time corresponding to the turnout equipment.

[0060] Therefore, in step S3, the obtained first state, or the first state and the second state, are matched with the state information in the second column of Table 1, and the fault information corresponding to the successfully matched state information is taken as the target fault information of the turnout equipment.

[0061] Subsequently, the target fault information of the turnout equipment can be output to the user terminal through a display screen or network transmission, so that users or maintenance personnel can promptly grasp the target fault information of the turnout equipment and take corresponding maintenance measures in a timely manner.

Then, it extracts features from the timing signals to determine the first state of the locking relay when it is activated, the operating relay, and the reverse relay, as well as the second state of other turnout relays within the corresponding delay time. Finally, based on the first state, or based on the first and second states, it matches them with a preset fault mode to determine the target fault information of the turnout equipment. This method utilizes the timing signals of the turnout relay circuit and introduces a preset fault mode to determine the target fault information. It enables real-time monitoring and fault diagnosis of the turnout equipment without affecting its normal operation, quickly determining whether a fault exists.
