Description

Technical Field

[0001] The present disclosure relates generally to control head monitors. More specifically, the present disclosure relates to systems and methods for verifying the operational integrity of a control head monitor. Background Art

[0002] A control head monitor (CHM) is typically mounted to a supervisory circuit that monitors integrity at the ends of a line resistor. Compromised integrity in the supervisory circuit can be distinguished from a supervisory alarm because of the difference between a signal indicating a break and a signal indicating a short. However, there are internal leads within the housing of the CHM where a break from an open circuit cannot be distinguished by the switching system. Therefore, an improved detection method and system for determining the operational integrity of a control head monitor is desired. Summary of the invention

[0003] This Summary is provided to introduce a selection of concepts in a simplified format that are further described in the Detailed Description of the disclosure.

DETAILED DESCRIPTION

[0027] To facilitate an understanding of the principles of the present disclosure, reference will now be made to various embodiments, and specific language will be used to describe these embodiments. It will be understood, however, that no limitation of the scope of the present disclosure is intended thereby, and such changes and further modifications in the illustrated systems and such further applications of the principles of the present disclosure as illustrated herein are contemplated as would normally occur to one skilled in the art to which the present disclosure relates.

[0028] Those skilled in the art will understand that the foregoing general description and the following detailed description are illustrative of the present disclosure and are not intended to limit the present disclosure.

[0029] References throughout this specification to "aspect," "another aspect," or similar language mean that a particular feature, structure, or characteristic described in connection with an embodiment is included in at least one embodiment of the present disclosure. Thus, appearances of the phrases "in an embodiment," "in another embodiment," "some embodiments," "one or more embodiments," and similar language throughout this specification may, but do not necessarily, all refer to the same embodiment.

[0030] The terms "comprises", "includes" or any other variation thereof are intended to cover a non-exclusive inclusion, such that a process or method that includes a series of steps includes not only those steps but may also include other steps not expressly listed or inherent to such process or method. Similarly, one or more devices or subsystems or elements or structures or parts performed by "comprising..." do not exclude the presence of other devices or other subsystems or other elements or other structures or other parts or additional devices or additional subsystems or additional elements or additional structures or additional parts without more constraints.

[0031] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0032] Figure 1A A schematic representation of a control head monitor 100 is shown. Figure 1B A circuit diagram representation of a control head monitor 100 is shown. The control head monitor 100 includes a single pole double throw (SPDT) switch 101 having a first terminal 101a, a second terminal 101b, a third terminal 101c, and a switch element 102. A load element 103 is connected between an input line 104 and the second terminal 101b. More specifically, the load element 103 is connected on a bypass line 106 between the input line 104 and the second terminal 101b. In an embodiment, the load element 103 is at least one of a resistor, a diode, an inductor, and a capacitor.

[0033] It will be appreciated that while the load element 103 may be assumed to be a resistor, diode, inductor, or combination thereof; any circuit element may alternatively be used that, when engaged or included as part of the monitored circuit, will result in a signal output that is identifiably different from an open circuit condition or a condition when the circuit element in question is bypassed by a "short circuit" condition. For example, by using a typical resistor arrangement, a high or infinite resistance may be possible when the circuit is open / incomplete, a medium or specific resistance (e.g., 10 ohms for a 10 ohm resistor) may be possible when the resistor is an engaged part of a closed circuit, or a low or zero resistance may be possible when the circuit has a completed path that bypasses the resistor. Therefore, if another load element could be used to produce a medium or specific resistance that is the opposite of an open circuit or short circuit condition, then the switch arrangement would theoretically also be useful because the arrangement facilitates switching between these three possible output conditions.

[0034] An input line 104 of the detection circuit is connected to the first terminal 101a, and an output line 105 of the detection circuit is connected to the third terminal 101c. During the off mode, the switch element 102 is adapted to connect the first terminal 101a and the third terminal 101c. Since the first terminal 101a and the third terminal 101c are connected, the input signal supplied through the input line 104 is transmitted as an output signal through the output line 105. The input signal can be provided to the SPDT switch 101 to determine whether the internal wiring of the control head monitor 100 is unbroken or undamaged.

[0035] As used herein, the “on mode” of the control head monitor 100 refers to a state where the control head monitor 100 is mounted, and the “off mode” of the control head monitor 100 refers to a state where the control head monitor 100 is uninstalled or disassembled.

[0036] During the on mode, the switch element 102 is adapted to connect the second terminal 101b and the third terminal 101c. Since the second terminal 101b and the third terminal 101c are connected, the input signal supplied through the input line 104 is transmitted to the output line 105 as an output signal through the load element 103 on the bypass line 106. Therefore, during the off mode and the on mode of the control head monitor 100, if the internal lead of the control head monitor 100 is not broken or damaged, the input signal provided must generate an output signal.

[0037] However, if there is an internal break or damage to the wiring, then the absence of an output signal is generated. During the off mode and during the on mode, at least one of the output signal or the absence of an output signal is generated. Thus, by using a detection circuit, the output signal or the absence of an output signal can be detected to determine whether a notification or alarm must be generated to notify security personnel.

[0038] Figure 2A A block diagram representation of a system 200 for verifying the operational integrity of a control head monitor 100 is shown. The system 200 includes a control head monitor 100 having a single pole double throw (SPDT) switch 101 having a first terminal 101a, a second terminal 101b, a third terminal 101c, and a switching element 102. A load element 103 is connected between an input line 104 and the second terminal 101b. Figure 1B As shown, the input line 104 of the detection circuit is connected to the first terminal 101a and the output line 105 of the detection circuit is connected to the third terminal 101c. The detection circuit 201 includes at least one controller 202 coupled to the input line 104 and the output line 105.

[0039] More specifically, at least one controller 202 is connected to the SPDT switch 101 and the load element 103 via an input line 104 and an output line 105. The at least one controller 202 is adapted to receive at least one of the generated output signal and the absence of the output signal during the off mode and the on mode of the control head monitor 100. This means that the at least one controller 202 is adapted to receive the generated output signal or the absence of the output signal during the off mode and the on mode, respectively. The at least one controller 202 verifies the operational integrity of the control head monitor 100 based on at least one of the output signal and the absence of the output signal received during the off mode and the on mode of the control head monitor 100. This means that if there is no output signal during the off mode and / or the on mode, the at least one controller 202 determines the operational integrity as impaired. Alternatively, if the output signal is generated for both the off mode and the on mode, respectively, the at least one controller 202 verifies the operational integrity of the control head monitor 100.

[0040] As used herein, the term "operational integrity" refers to the normal function or expected functional status of the control head monitor 100 disclosed herein. With long-term use, over the years, various components such as internal wiring, power lines, terminals, etc. are prone to wear or damage. This prevents the control head monitor 100 from functioning as intended or designed. Therefore, the operational integrity of the system 200 is compromised. Therefore, regular inspections are required to determine the operational integrity or system readiness.

[0041] As used herein, the term "at least one controller 202" may be interpreted to encompass one or a combination of a microprocessor, suitable logic, circuitry, a printed circuit board (PCB), an audio interface, a visual interface, a tactile interface, etc. The at least one controller 202 may include, but is not limited to, a microcontroller, a reduced instruction set computing (RISC) processor, an application specific integrated circuit (ASIC) processor, a complex instruction set computing (CISC) processor, a central processing unit (CPU), a graphics processing unit (GPU), a state machine, and / or other processing units or circuits.

[0042] The at least one controller 202 may also include suitable logic, circuitry, interfaces, and / or code that may be configured to execute instruction sets stored in a memory unit. In an exemplary embodiment, the memory unit may include, but is not limited to, an electrically erasable programmable read-only memory (EEPROM), a random access memory (RAM), a read-only memory (ROM), a hard disk drive (HDD), a flash memory, a solid-state drive (SSD), and / or a CPU cache memory.

[0043] In an exemplary embodiment, at least one controller 202 may receive power from a suitably coupled power source. For example, a suitably coupled power source may be electrically coupled to at least one controller 202 for supplying power. In an embodiment, the power source may be, for example, a battery, such as a rechargeable battery or a non-rechargeable battery. Examples of suitable batteries include, for example, lithium batteries (such as lithium-ion batteries), nickel batteries (such as nickel-cadmium batteries), and alkaline batteries.

[0044] Figure 2B Shown by Figure 2AA set of sample output signals generated by the system 200 for verifying the operational integrity of the control head monitor 100 is shown. The step of verifying the operational integrity of the control head monitor 100 includes first comparing at least one of the generated output signal or the absence of the output signal received during the on mode with at least one of the generated output signal or the absence of the output signal received during the off mode. Next, based on the comparison of the output signal generated and the absence of the output signal during the on mode and the off mode, the input line (104), the output line (105), and the bypass line (106) through the load element (103) are identified as being in an undamaged state. This means that during the on mode and the off mode of the control head monitor 100, the output signal is generated or detected by the detection circuit 201 at the output line 105 to be identified as being in an undamaged state. If the output signal is not present during the on mode and / or the off mode of the control head monitor 100, the input line 104, the output line 105, and the bypass line 106 cannot be identified as being in an undamaged state. The controller 202 is adapted to generate a first notification based on the input line 104, the output line 105, and the bypass line 106 through the load element 103 being identified as being in an undamaged state. The first notification may be at least one of a visual notification, an audio notification, an audio-visual notification, and a tactile notification. For example, the first notification may be a visual notification, such as “system ready”, “system OK”, etc.

[0045] The step of verifying the operational integrity of the control head monitor 100 may include first comparing at least one of the generated output signal or the absence of the output signal received during the on mode with at least one of the generated output signal or the absence of the output signal received during the off mode. Next, based on the comparison of at least one of the generated output signal and the absence of the output signal during the on mode and the off mode, at least one of a portion of the input line 104, a portion of the output line 105, and / or a portion of the bypass line 106 through the load element 103 is identified as being in a damaged state. This means that during the on mode and / or the off mode of the control head monitor 100, the output signal is not present or is not detected by the detection circuit 201 at the output line 105 to be identified as being in a damaged state. If there is no output signal during the on mode and / or the off mode of the control head monitor 100, at least a portion of the input line 104, a portion of the output line 105, and / or a portion of the bypass line 106 may be identified as being in a damaged state. The controller 202 is adapted to generate a second notification based on at least one of a portion of the input line 104, a portion of the output line 105, and a portion of the bypass line 106 passing through the load element 103 being identified as being in a damaged state. The second notification may be at least one of a visual notification, an audio notification, an audio-visual notification, and a tactile notification. For example, the second notification may be a visual notification, such as "system failure", "fault", "alarm", "problem", "supervisory alarm", etc.

[0046] The system 200 is also adapted to identify a specific portion (15, 16, 17, 18, 19, 20) of the input line 104, a specific portion (1, 2, 3, 4, 5) of the output line 105, and / or a specific portion (6, 7, 8, 9, 10, 11, 12, 13, 14) of the bypass line 106 as being in a damaged state. This is exemplarily shown by the sample table 203. Column 203a of the table 203 represents the second notification during the on mode, and column 203b represents the second notification during the off mode. By comparing the second notification generated during the on mode and the off mode, the controller 202 can determine that the specific portion (15, 16, 17, 18, 19, 20) of the input line 104, the specific portion (1, 2, 3, 4, 5) of the output line 105, and / or the specific portion (6, 7, 8, 9, 10, 11, 12, 13, 14) of the bypass line 106 is in a damaged state.

[0047] For example, if a specific part (1, 2, 3, 4, 5) of the output line 105 is damaged, the detection circuit 201 does not detect an output signal at the output line 105 during the on-mode and the off-mode. Therefore, the second notification "fault" is displayed during the on-mode and the off-mode. In this way, if the second notification "fault" is generated during both the on-mode and the off-mode, the inspection or maintenance personnel can quickly identify that at least one of the specific parts (1, 2, 3, 4, 5) is damaged. This feature ensures rapid identification and resolution of the problem.

[0048] In another case, if a specific portion (6, 7, 8, 9, 10, 11, 12, 13, 14) of the bypass line 106 is damaged, the detection circuit 201 does not detect an output signal at the output line 105 during the on-mode. During the off-mode, the output signal is detected at the output line 105. In this way, if a second notification "fault" is generated during the on-mode and a second notification "supervision" is generated during the off-mode, the inspection or maintenance personnel can quickly identify that at least one of the specific portions (6, 7, 8, 9, 10, 11, 12, 13, 14) of the bypass line 106 is damaged. In an embodiment, a "supervision" alarm can be generated when the panel sees a short circuit that does not have a specified resistance (resistance is closer to zero), while a "fault" alarm can be generated when the loop is open (resistance is actually infinite). This feature ensures rapid identification and resolution of problems.

[0049] Similarly, if the specific portion (15, 16, 17, 18, 19, 20) of the input line 104 is damaged, the second notification "TROUBLE" is generated during the off mode. In this way, if the second notification "OK" is generated during the on mode and the second notification "FAULT" is generated during the off mode, the inspection or maintenance personnel can quickly recognize that at least one of the specific portions (17, 18, 19, 20) is damaged. On the other hand, if the second notification "FAULT" is generated during the on mode and the second notification "FAULT" is generated during the off mode, the inspection or maintenance personnel can quickly recognize that at least one of the specific portions (15, 16) is damaged.

[0050] Figure 3 A flow chart is shown indicating a method 300 for verifying the operational integrity of a control head monitor. Figure 1A-Figure 2B The details of the present disclosure explained in the description are not Figure 3 Explained in the description.

[0051] A method 300 for verifying the operational integrity of a control head monitor 100 is disclosed. The method 300 includes: at step 301, providing a control head monitor 100 including a single pole double throw switch (SPDT) 101 having a first terminal 101a, a second terminal 101b, a third terminal 101c, and a switch element 102, a load element 103 being connected between an input line 104 and the second terminal 101b. An input line 104 of a detection circuit is connected to the first terminal 101a, and an output line 105 of the detection circuit is connected to the third terminal 101c. The switch element 102 is adapted to connect the first terminal 101a and the third terminal 101c during an off mode. The switch element 102 is adapted to connect the second terminal 101b and the third terminal 101c during an on mode to generate at least one of an output signal and an absence of an output signal.

[0052] At step 302 , at least one controller 202 of the detection circuit 201 receives at least one of a generated output signal and an absence of an output signal during an off mode and an on mode of controlling the head monitor 100 .

[0053] At step 303 , at least one controller 202 verifies the operational integrity of the control head monitor 100 based on at least one of the output signals received and the absence of output signals during the off mode and the on mode of the control head monitor 100 .

[0054] Since the control head monitor 100 utilizes the SPDT switch 101, complex modifications to existing control head monitors 100 or existing systems are eliminated. The system 200 allows for easy monitoring and diagnosis of potential damage or breaks to the internal leads or wiring of the control head monitor 100.

[0055] As in Figure 1A-Figure 2B As discussed in the detailed description of , by analyzing the output signal or the absence of the output signal at the output line 105, the controller 202 can determine that a specific portion (15, 16, 17, 18, 19, 20) of the input line 104, a specific portion (1, 2, 3, 4, 5) of the output line 105, and / or a specific portion (6, 7, 8, 9, 10, 11, 12, 13, 14) of the bypass line 106 is in a damaged state. This allows maintenance or inspection personnel to quickly identify problems associated with the control head monitor 100, thereby ensuring a quick resolution and reduced downtime.

[0056] It will be apparent to those skilled in the art that various working modifications may be made to the methods in order to implement the inventive concepts taught herein.

[0057] In addition, the actions of any flow chart do not need to be implemented in the order shown; nor do they need to perform all actions. In addition, those actions that are not dependent on other actions can be performed in parallel with other actions.
