Description

Technical Field

[0001] This utility model belongs to the field of turnout control technology, specifically relating to an indoor and outdoor consistency monitoring device for railway turnouts. Background Technology

[0002] Railway turnouts are critical components of railway track structures, and their correct positioning directly affects train operation safety and transportation efficiency. In railway signal control systems, turnout position information is indicated both indoors and outdoors. Indoors, the turnout position is determined by collecting information from the turnout indicator circuits through the interlocking system, while outdoors, the actual position of the turnout switch machine is manually confirmed to verify whether the indoor and outdoor turnout positions match.

[0003] Indoor turnout location acquisition technology has reached a mature and stable stage of development. Through long-term practical application and technological iteration, the relevant data acquisition methods have undergone multiple tests and optimizations, demonstrating excellent performance in terms of both hardware durability and stability.

[0004] Compared to the mature and stable indoor turnout location acquisition, outdoor turnout location acquisition faces more complex and variable environmental challenges and technical difficulties. Due to the openness and uncertainty of the outdoor environment, factors such as severe weather conditions, complex electromagnetic interference, and frequent mechanical vibrations all pose significant threats to the accuracy and stability of the acquisition.

[0005] Therefore, there is a need to provide a railway turnout outdoor position consistency monitoring device, which aims to achieve accurate and reliable collection of outdoor turnout position information in complex outdoor environments, thereby providing strong technical support and guarantee for the accurate determination of the indoor and outdoor position consistency of railway turnouts and the overall railway operation safety.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] like Figure 1 As shown, this embodiment provides a railway turnout indoor-outdoor consistency monitoring device, including:

[0023] The position indication contact status acquisition module includes a positioning acquisition module and a reverse position acquisition module; the positioning acquisition module is connected to the positioning indication contact of the switch machine and is used to acquire the on-state voltage signal and off-state voltage signal of the positioning indication contact; the reverse position acquisition module is connected to the reverse position indication contact of the switch machine and is used to acquire the on-state voltage signal and off-state voltage signal of the reverse position indication contact.

[0024] The turnout outdoor position determination module is connected to the position indicator contact status acquisition module and is used to output the turnout outdoor position determination result based on the acquired on-state voltage signal and off-state voltage signal of the position indicator contact and the acquired on-state voltage signal and off-state voltage signal of the reverse position indicator contact.

[0025] The indoor centralized monitoring module is used to output the indoor position determination results of the turnout;

[0026] The centralized monitoring module is connected to both the outdoor turnout position determination module and the indoor centralized monitoring module. It is used to compare the consistency between the received outdoor turnout position determination results and the indoor turnout position determination results, and to output an alarm when the indoor and outdoor turnout positions are inconsistent.

[0027] In this embodiment, the turnout outdoor position determination module can be implemented using a microcontroller, microprocessor, etc., such as TMS320DM365ZCED.

[0028] In this embodiment, the positioning acquisition module and the reverse position acquisition module at one end of the position indication contact status acquisition module are connected to the positioning and reverse position indication contacts of the outdoor turnout switch machine, and the other end outputs a specific voltage signal.

[0029] Each switch machine uses two modules: a positioning acquisition module and a reversing acquisition module, which respectively acquire the fixed and reverse positions of the switch machine. When the switch is in the fixed position, the positioning acquisition module outputs an on-state voltage signal for the positioning indicator contact (referred to as the "fixed position on signal"), and the reversing acquisition module outputs an off-state voltage signal for the reversing indicator contact (referred to as the "reversing position off signal"). When the switch is in the reverse position, the positioning acquisition module outputs an off-state voltage signal for the positioning indicator contact (referred to as the "fixed position off signal"), and the reversing acquisition module outputs an on-state voltage signal for the reversing indicator contact (referred to as the "reversing position on signal"). The outdoor switch position determination module receives both the fixed position on signal and the reversing position off signal simultaneously, determining the current outdoor switch position as fixed and outputting a result indicating a fixed position. Conversely, it receives both the fixed position off signal and the reversing position on signal simultaneously, determining the current outdoor switch position as reverse and outputting a result indicating a reverse position.

[0030] In some exemplary embodiments, both the positioning acquisition module and the reversing acquisition module include an isolated power supply module and an isolated acquisition module; the isolated power supply module includes an IF1205S-1WR3 power chip to provide a 5V voltage input to the isolated acquisition module; the isolated acquisition module includes a PS2801 optocoupler, one end of which is connected to the switch machine as an acquisition input terminal, and the other end of which is connected as an acquisition output terminal.

[0031] In this embodiment, the positioning acquisition module and the reverse position acquisition module adopt an isolated power supply and isolated acquisition circuit design, which can ensure accurate and reliable acquisition of outdoor turnout position information even when facing complex and ever-changing environmental challenges such as severe weather conditions, complex electromagnetic interference and frequent mechanical vibrations.

[0032] Specifically, such as Figure 2 As shown, the isolated power supply module also includes a fuse F1, a Zener diode D1, capacitors C1 and C2, a resistor R6, and an indicator light D5. The VIN pin of the IF1205S-1WR3 power chip is connected to a 12V voltage through the fuse F1, and the GND pin is connected to GND. The Zener diode D1 and the capacitor C1 are connected in parallel between the VIN pin and the GND pin of the IF1205S-1WR3 power chip, respectively. The VO+ pin of the IF1205S-1WR3 power chip is connected to GND0 through the resistor R6 and the indicator light D5, and the 0V pin is grounded to GND0. The capacitor C2 is connected in parallel between the VO+ pin and the 0V pin of the IF1205S-1WR3 power chip. The VO+ pin of the IF1205S-1WR3 power chip outputs a 5V voltage, and the VIN pin outputs a 12V voltage.

[0033] The isolation acquisition module also includes resistors R1-R5, transistor Q1, indicator light D3, diode D4, and Zener diode D2;

[0034] The first input pin of the PS2801 optocoupler is connected to the emitter of transistor Q1. The collector of transistor Q1 is connected to a 5V voltage. Resistor R1 is connected between the collector and base of transistor Q1. The base of transistor Q1 is connected to the switch machine as a data acquisition input terminal through resistor R3. The second input pin of the PS2801 optocoupler is connected to GND0 through resistor R4 and indicator light D3. The third input pin of the PS2801 optocoupler is connected to GND through resistor R5 and diode D4. The fourth input pin of the PS2801 optocoupler serves as a data acquisition output terminal, connected to a 12V voltage through resistor R2, and also connected to GND through Zener diode D2.

[0035] In some exemplary embodiments, outdoor turnout switch machines can be classified into two main categories based on their power supply type: AC switch machines and DC switch machines. For example... Figure 3 The diagram shows the turnout control circuit of an AC switch machine. The fixed and reverse positions of the AC switch machine are indicated by contacts 31-32 and 21-22, respectively. Figure 4 The diagram shows the turnout control circuit of a DC switch machine. The fixed and reverse position indicators for the DC switch machine are 15-16 and 45-46, respectively.

[0036] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
