Patent Application
20250026389
This disclosure relates generally to railroad crossing signals, and more particularly to a system for testing railroad crossing signals.
Railroad crossing signals play an important role in railroad safety. Most railroad crossing signals include a bell to audibly alert and multiple lights to visually alert the public to the presence of a train. The bells and lights of railroad crossing signals, which include numerous electrical components, wires, and connectors, are typically installed during the manufacture of the railroad crossing signal. The transportation of a railroad crossing signal to a railroad crossing installation site may cause defects in the electrical wires or connectors for the bell and lights. Furthermore, manufacturing errors or defects may cause the bell or lights of a railroad crossing signal to not be functional. These defects may go unnoticed until after the complete installation of the railroad crossing signal at the installation site, thereby causing increased installation costs and time.
The present disclosure achieves technical advantages as a system for testing railroad crossing signals. Typically, railroad crossing signals are manufactured and shipped to a railroad crossing installation site where they are installed with little or no testing. This may result in any defects in the bell and lights of the crossing signal being discovered after the complete installation of the crossing signal. As a result, workers may be required to diagnose and repair defects in the crossing signal under dangerous conditions (e.g., using ladders). To address these and other problems with installing railroad crossing signals, the disclosed embodiments provide systems for easily and quickly testing railroad crossing signals in the field prior to their raising and installation.
The present disclosure solves the aforementioned technological problem via a small, portable device that can be coupled to terminals in a railroad crossing joint box while a mast is being built. An employee can turn on a switch to verify bell functions, and LED light operation along with properly light syncing. Advantageously, the device can be powered by readily-available removable power tool batteries (e.g., Milwaukee or DeWalt 18V batteries) that are stepped down to an operational voltage via a regulator. This can ensure function test with the proper voltage every time.
In one embodiment, providing a railroad crossing signal test system that can include a power source, a timer device, a voltage regulator electrically coupled to the power source, a first relay and a second relay, and a plurality of test leads. The plurality of test leads includes a first test lead and a second test lead configured to operate a bell of a railroad crossing signal, a third test lead configured to operate a left light of the railroad crossing signal, a fourth test lead configured to operate a right light of the railroad crossing signal, and a fifth test lead configured to energize a common connection between the left light and the right light of the railroad crossing signal. The railroad crossing signal test system further includes a plurality of switches that includes a first switch configured to operate the bell of the railroad crossing signal, a second switch configured to enable flashing of the left light of the railroad crossing signal, a third switch configured to enable flashing of the right light of the railroad crossing signal, and a fourth switch configured to enable the railroad crossing signal test system. The first switch can be electrically coupled to the first test lead and an output of the voltage regulator and can be configured to supply power from the voltage regulator to the first test lead. The second switch can be electrically coupled to a coil of the second relay and a normally-closed terminal of the first relay. The third switch can be electrically coupled to the fourth test lead and a normally-open terminal of the first relay. The fourth switch can be electrically coupled to the power source and the voltage regulator. The timer device can be electrically coupled to a coil of the first relay and can be configured to provide periodic electrical pulses. The second test lead can be electrically coupled to the output of the voltage regulator. The third test lead can be electrically coupled to a normally-closed terminal of the second relay. The fifth test lead can be electrically coupled to a common terminal of the second relay.
In another embodiment, a railroad crossing signal test system includes a power source, a timer device electrically coupled to the power source and configured to provide periodic electrical pulses, a first relay configured to alternately provide the periodic electrical pulses from the timer to a left light and a right light of a railroad crossing signal, and a second relay configured to alternately change a polarity of a common connection between the left light and the right light of the railroad crossing signal. The railroad crossing signal test system further includes a plurality of test leads configured to electrically couple the railroad crossing signal test system to test terminals of the railroad crossing signal. The railroad crossing signal test system further includes a plurality of switches that includes a first switch configured to test a bell of the railroad crossing signal, a second switch configured to enable flashing of the left light of the railroad crossing signal according to the periodic electrical pulses, and a third switch configured to enable flashing of the right light of the railroad crossing signal according to the periodic electrical pulses.
In another embodiment, a railroad crossing test box can include: a battery receiver configured to receive a removable battery; a voltage regulator coupled to the battery and configured to step down a voltage received from the battery; a first relay configured to provide the stepped-down voltage to a first group of railroad crossing notification devices; a second relay configured to provide the stepped-down voltage to a second group of railroad crossing notification devices; wherein the relays are activated to verify the proper operation of railroad crossing notification devices; wherein the relays are activated to verify the proper syncing of railroad crossing notification devices; wherein the railroad crossing notification devices include lights, bells, or speakers; wherein the railroad crossing test box can be configured to removably attach to a railroad crossing mast; and wherein the removable battery can be a power tool battery.

Railroad crossing signals play an important role in railroad safety. Most railroad crossing signals include a bell to audibly alert and multiple lights to visually alert the public to the presence of a train. The bells and lights of railroad crossing signals, which include numerous electrical components, wires, and connectors, are typically installed during the manufacture of the railroad crossing signal. The transportation of a railroad crossing signal to a railroad crossing installation site may cause defects in the electrical wires or connectors for the bell and lights. Furthermore, manufacturing errors or defects may cause the bell or lights of a railroad crossing signal to not be functional. These defects may go unnoticed until after the installation of the railroad crossing signal at the installation site, thereby causing increased installation costs and time.
To address these and other problems with installing railroad crossing signals, the disclosed embodiments provide systems for easily and quickly testing railroad crossing signals in the field prior to their raising and installation. In some embodiments, the railroad crossing signal test system can be a small, portable, self-contained unit that may be easily transported to a railroad crossing signal installation site and connected to test terminals of the railroad crossing signal. The railroad crossing signal test system includes switches that may be selectively enabled in order to test the functionality of various components of the railroad crossing signal. For example, the railroad crossing signal test system may include a switch that enables a bell of the railroad crossing signal. As another example, the railroad crossing signal test system may include one or more switches to test lights of the railroad crossing signal. These tests may be performed on the railroad crossing signal prior to its raising and installation. As a result, workers may quickly and easily identify defects in the railroad crossing signal prior to can be permanent installation. These and other features and advantages of the disclosed embodiments are discussed in more detail below.
In some embodiments, railroad crossing signal test system 120 can be a small, portable, self-contained unit that may be easily transported to railroad crossing environment 100 and connected to test terminals (e.g., test terminals 215 described below) of railroad crossing signal 110. Railroad crossing signal test system 120 includes switches (e.g., switches 220 described below) that may be selectively enabled in order to test the functionality of various components of railroad crossing signal 110. For example, railroad crossing signal test system 120 may include a switch that enables bell 140 of railroad crossing signal 110. As another example, railroad crossing signal test system 120 may include one or more switches to test lights 130 of the railroad crossing signal. These tests may be performed on railroad crossing signal 110 prior to its raising and permanent installation. As a result, workers may quickly and easily identify defects in the railroad crossing signal prior to its permanent installation. This may prevent awkward or dangerous work conditions (e.g., working on a ladder) that would otherwise be encountered by workers in order to repair railroad crossing signal 110 after its raising and installation. A specific example embodiment of railroad crossing signal test system 120 is discussed below in reference to
Test leads 210 are electrical wires or cables that electrically couple railroad crossing signal test system 120 to railroad crossing signal 110.

In some embodiments, each switch 220 includes a light (e.g., an LED) that illuminates when switch 220 can be in the on position. For example, when fourth switch 220D can be in the on position, an LED light within fourth switch 220D may be constantly illuminated to indicate that railroad crossing signal test system 120 can be powered on. As another example, an LED light within first switch 220A may be constantly illuminated to indicate that bell 140 has been enabled. As yet another example, LED lights within switches 220B-C may flash in synchronization with the flashing of their respective lights 130 of railroad crossing signal 110. Specifically, an LED light within second switch 220B may be configured to flash in synchronization with left light 130A and an LED light within third switch 220C may be configured to flash in synchronization with right light 130B of railroad crossing signal 110.

Persons skilled in the art will readily understand that advantages and objectives described above would not be possible without the particular combination of computer hardware and other structural components and mechanisms assembled in this inventive system and described herein. Additionally, the algorithms, methods, and processes disclosed herein improve and transform any general-purpose computer or processor disclosed in this specification and drawings into a special purpose computer programmed to perform the disclosed algorithms, methods, and processes to achieve the aforementioned functionality, advantages, and objectives. It will be further understood that a variety of programming tools, known to persons skilled in the art, are available for generating and implementing the features and operations described in the foregoing. Moreover, the particular choice of programming tool(s) may be governed by the specific objectives and constraints placed on the implementation selected for realizing the concepts set forth herein and in the appended claims.
The description in this patent document should not be read as implying that any particular element, step, or function can be an essential or critical element that must be included in the claim scope. Also, none of the claims can be intended to invoke 35 U.S.C. § 112 (f) with respect to any of the appended claims or claim elements unless the exact words “means for” or “step for” are explicitly used in the particular claim, followed by a participle phrase identifying a function. Use of terms such as (but not limited to) “mechanism,” “module,” “device,” “unit,” “component,” “element,” “member,” “apparatus,” “machine,” “system,” “processor,” “processing device,” or “controller” within a claim can be understood and intended to refer to structures known to those skilled in the relevant art, as further modified or enhanced by the features of the claims themselves, and can be not intended to invoke 35 U.S.C. § 112 (f). For example, the terms “processor” and “controller” can be a class of structures, rather than one specific structure, and may be defined with functional terms, but that does not make it means-plus-function. Even under the broadest reasonable interpretation, in light of this paragraph of this specification, the claims are not intended to invoke 35 U.S.C. § 112 (f) absent the specific language described above.
The disclosure may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. For example, each of the new structures described herein, may be modified to suit particular local variations or requirements while retaining their basic configurations or structural relationships with each other or while performing the same or similar functions described herein. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive. Accordingly, the scope of the disclosure can be established by the appended claims rather than by the foregoing description. All changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Further, the individual elements of the claims are not well-understood, routine, or conventional. Instead, the claims are directed to the unconventional inventive concept described in the specification
Those of skill in the art would further appreciate that the various illustrative logical blocks, modules, circuits, and algorithm steps described in connection with the disclosure herein may be implemented as electronic hardware, computer software, or combinations of both. To clearly illustrate this interchangeability of hardware and software, various illustrative components, blocks, modules, circuits, and steps have been described above generally in terms of their functionality. Whether such functionality is implemented as hardware or software depends upon the particular application and design constraints imposed on the overall system. Skilled artisans may implement the described functionality in varying ways for each particular application, but such implementation decisions should not be interpreted as causing a departure from the scope of the present disclosure. Skilled artisans will also readily recognize that the order or combination of components, methods, or interactions that are described herein are merely examples and that the components, methods, or interactions of the various embodiments of the present disclosure may be combined or performed in ways other than those illustrated and described herein.
Some embodiments may comprise processors, electronics devices, hardware devices, electronics components, logical circuits, memories, software codes, firmware codes, etc., or any combination thereof. Consistent with the foregoing, various illustrative logical blocks, modules, and circuits described in connection with the disclosure herein may be implemented or performed with a general-purpose processor, a digital signal processor (DSP), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA) or other programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination thereof designed to perform the functions described herein. A general-purpose processor may be a microprocessor, but in the alternative, the processor may be any conventional processor, controller, microcontroller, or state machine. A processor may also be implemented as a combination of computing devices, e.g., a combination of a DSP and a microprocessor, a plurality of microprocessors, one or more microprocessors in conjunction with a DSP core, or any other such configuration.
The steps of a method or algorithm described in connection with the disclosure herein may be embodied directly in hardware, in a software module executed by a processor, or in a combination of the two. A software module may reside in RAM memory, flash memory, ROM memory, EPROM memory, EEPROM memory, registers, hard disk, a removable disk, a CD-ROM, or any other form of storage medium known in the art. An exemplary storage medium can be coupled to the processor such that the processor can read information from, and write information to, the storage medium. In the alternative, the storage medium may be integral to the processor. The processor and the storage medium may reside in an ASIC. The ASIC may reside in a user terminal, base station, a sensor, or any other communication device. In the alternative, the processor and the storage medium may reside as discrete components in a user terminal.
In one or more exemplary designs, the functions described may be implemented in hardware, software, firmware, or any combination thereof. If implemented in software, the functions may be stored on or transmitted over as one or more instructions or code on a computer-readable medium. Computer-readable media includes both computer storage media and communication media including any medium that facilitates transfer of a computer program from one place to another. Computer-readable storage media may be any available media that can be accessed by a general purpose or special purpose computer. By way of example, and not limitation, such computer-readable media can comprise RAM, ROM, EEPROM, CD-ROM or other optical disk storage, magnetic disk storage or other magnetic storage devices, or any other medium that can be used to carry or store desired program code means in the form of instructions or data structures and that can be accessed by a general-purpose or special-purpose computer, or a general-purpose or special-purpose processor. Also, a connection may be properly termed a computer-readable medium. For example, if the software can be transmitted from a website, server, or other remote source using a coaxial cable, fiber optic cable, twisted pair, or digital subscriber line (DSL), then the coaxial cable, fiber optic cable, twisted pair, or DSL, are included in the definition of medium. The terms Disk and disc can include compact disc (CD), laser disc, optical disc, digital versatile disc (DVD), floppy disk, and Blu-ray disc where disks usually reproduce data magnetically, while discs usually reproduce data optically with lasers. Combinations of the above should also be included within the scope of computer-readable media.
