Description

Technical Field

[0001] This application relates to the field of industrial safety control, specifically to a method and system for safe equipment startup. Background Technology

[0002] When existing coal preparation equipment is started on-site, the audible and visual alarms are independently controlled from the equipment start-up system, without any hard linkage. Relying on manual operation, it is easy for negligence to cause the equipment to start before the alarm is activated, resulting in safety risks such as mechanical injury to nearby personnel who fail to notice the equipment starting in time. At the same time, the lack of hard logical constraints makes it difficult to prevent violations of operating procedures by relying solely on operating specifications. Furthermore, allowing the equipment to start even when the alarm is abnormal or the start-up is delayed further amplifies safety hazards. In addition, the lack of intuitive fault indications makes it difficult to troubleshoot problems, seriously affecting operational safety and standardization.

[0003] CN113205653A discloses an alarm control method for an audible and visual alarm, characterized by comprising: acquiring a first control signal; controlling multiple cascaded audible and visual alarms to provide audible and visual warnings based on the first control signal; wherein the output control signal of the preceding stage audible and visual alarm in the cascaded multiple audible and visual alarms serves as the input control signal of the following stage audible and visual alarm. This prior art has the following drawbacks: there is no connection between the audible and visual alarm and the equipment, no hard linkage, posing a safety hazard; the interlocking mechanism is imperfect in case of failure; the alarm is allowed to activate even when malfunctioning; there is no intuitive fault indication; and the operational safety and standardization are insufficient. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the prior art, the present invention provides a method and system for safe device startup to solve the above-mentioned technical problems.

[0005] In a first aspect, the present invention provides a method for safe device startup, specifically comprising the following steps: Step S1: The step of sending the start request signal. The core control module receives the device start request signal sent by the operator through the human-machine interaction module and forcibly triggers the sound and light alarm module.

[0006] Step S2: The step of judging the start status of the audible and visual alarm module. After the core control module receives the device start request and triggers the start of the audible and visual alarm module, it immediately collects its working status signal through the status detection unit to judge whether the audible and visual alarm module has started normally and decides to enter the forced warning stage or block the device start stage. The human-machine interaction module displays the status information in real time. The core control module determines whether the audible and visual alarm module is started normally. If the audible and visual alarm module is started abnormally, the core control module receives the startup abnormality information and blocks the device startup process, locking the device startup function. At the same time, the human-machine interaction module displays the startup abnormality of the audible and visual alarm module and the corresponding abnormality information. Among them, the abnormal start-up information of the sound and light alarm module includes power failure, sound alarm unit failure and light alarm unit failure. The power failure is that the power supply voltage or current of the sound and light alarm module exceeds the normal range. The sound alarm unit failure is that the buzzer, voice player, etc. do not emit alarm signals. The light alarm unit failure is that the strobe light, etc. do not generate light alarm signals. If the audible and visual alarm module starts normally, the core control module receives the normal start information and controls the audible and visual alarm module to enter the forced warning stage. At the same time, the human-machine interaction module displays that the audible and visual alarm module starts normally. At this time, the device is prohibited from starting. The mandatory warning phase is set to last for 2 minutes.

[0007] Step S3: The steps to start the device. The sound and light alarm module starts normally. After the forced warning stage ends, the start request command takes effect and enters the preset countdown device start stage. The core control module determines whether the device has started successfully within the preset countdown. Furthermore, if the device starts successfully within the preset countdown, the status information is transmitted to the core control module, which then controls the audible and visual alarm module to turn off. At the same time, the human-machine interaction module displays that the device has started normally. After the equipment starts up successfully, the core control module continuously monitors the equipment's operating status through the start-up detection unit. If an abnormality occurs during the equipment's operation, the core control module immediately controls the equipment to stop running and simultaneously drives the audible and visual alarm module to restart to issue a fault alarm. The human-machine interaction module simultaneously displays the abnormal equipment operation information and the cause. The preset countdown timer for device startup is set to 1 minute.

[0008] If the device fails to start or malfunctions during the preset countdown, the status information is transmitted to the core control module. The core control module automatically locks the device startup function and re-executes steps S1-S3.

[0009] Secondly, the present invention provides a device safe startup system, specifically including a central processing unit, an early warning module, a human-machine interaction module, and a device execution module; The central processing unit is used to receive the device start request signal sent through the human-machine interaction module and control the early warning module and the device execution module to perform corresponding operations; The early warning module is used to issue early warnings based on the operation instructions given by the central processing unit; The human-computer interaction module interacts with the central processing unit to display status information in real time; The device execution module determines whether the device should be started based on the corresponding instructions from the central processing unit.

[0010] The central processing unit receives the device start request signal sent by the operator through the human-machine interface module, and determines whether the warning module has started normally. If the warning module starts abnormally, the central processing unit receives the start abnormal information and blocks the device start process, locks the device execution module, and at the same time, the human-machine interface module displays the warning module start abnormality and corresponding abnormal information. If the warning module starts normally, the central processing unit receives the start normal information and controls the warning module to enter the forced warning stage. At the same time, the human-machine interface module displays the warning module start normal, and the device is prohibited from starting. After the mandatory warning phase ends, the device start request command takes effect, and the device starts up in a preset countdown. If the device starts successfully within the preset countdown, the status information is transmitted to the central processing unit. The central processing unit controls the audible and visual alarm module to turn off. At the same time, the human-machine interface module displays that the device has started normally. After the device starts successfully, the central processing unit continuously monitors the device's operating status. If an abnormality occurs during the device's operation, the central processing unit immediately controls the device to stop running and drives the warning module to restart to issue a fault alarm. The human-machine interface module simultaneously displays the abnormal device operation information and the cause. If the device fails to start or malfunctions during the preset countdown, the status information is transmitted to the central processing unit. The central processing unit automatically locks the device startup function and re-monitors and issues warnings. The mandatory warning phase is set to 2 minutes, and the preset countdown device activation phase is set to 1 minute.

[0011] The beneficial effects of the present invention are that the device safe start-up method and system provided by the present invention realizes the hard linkage between the sound and light alarm and the device start-up system through the core control module, which can strictly control the device start-up sequence (such as starting only after a forced warning); at the same time, combined with the fault visualization operation, the status of the alarm can be fed back in real time, effectively avoiding safety hazards caused by the alarm not starting or malfunctioning, and further improving the safety and standardization of operation.

[0012] Furthermore, the design principle of this invention is reliable, the structure is simple, and it has a very wide range of application prospects.

[0013] Therefore, it is evident that the present invention has outstanding substantive features and significant progress compared with the prior art, and the beneficial effects of its implementation are also obvious. Attached Figure Description

The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0019] Example 1: like Figure 1 As shown, this embodiment of the invention provides a method for safe device startup, which specifically includes the following steps: Step S1: The step of sending the start request signal. The core control module receives the device start request signal sent by the operator through the human-machine interaction module and forcibly triggers the sound and light alarm module. Step S2: The step of judging the start status of the audible and visual alarm module. After the core control module receives the device start request and triggers the start of the audible and visual alarm module, it immediately collects its working status signal through the status detection unit to judge whether the audible and visual alarm module has started normally and decides to enter the forced warning stage or block the device start stage. The human-machine interaction module displays the status information in real time. Step S3: The steps to start the device. The sound and light alarm module starts normally. After the forced warning stage ends, the start request command takes effect and enters the preset countdown device start stage. The core control module determines whether the device has started successfully within the preset countdown. Example 2: like Figure 1 As shown, this embodiment of the invention provides a method for safe device startup, which specifically includes the following steps: Step S1: The step of sending the start request signal. The core control module receives the device start request signal sent by the operator through the human-machine interaction module and forcibly triggers the sound and light alarm module. Step S2: The step of judging the start status of the audible and visual alarm module. After the core control module receives the device start request and triggers the start of the audible and visual alarm module, it immediately collects its working status signal through the status detection unit to judge whether the audible and visual alarm module has started normally and decides to enter the forced warning stage or block the device start stage. The human-machine interaction module displays the status information in real time. Step S3: The steps to start the device. The sound and light alarm module starts normally. After the forced warning stage ends, the start request command takes effect and enters the preset countdown device start stage. The core control module determines whether the device has started successfully within the preset countdown. In some embodiments, in step S1, the core control module receives a device start request signal sent by the operator through the human-machine interaction module (by clicking the "Start Device" button on the human-machine interaction module), forcibly drives the relay output of the audible and visual alarm module to start the audible and visual alarm module, thus completing the linkage between the start request and the alarm trigger.

[0020] Example 3: like Figure 1 As shown, this embodiment of the invention provides a method for safe device startup, which specifically includes the following steps: Step S1: The step of sending the start request signal. The core control module receives the device start request signal sent by the operator through the human-machine interaction module and forcibly triggers the sound and light alarm module. Step S2: The step of judging the start status of the audible and visual alarm module. After the core control module receives the device start request and triggers the start of the audible and visual alarm module, it immediately collects its working status signal through the status detection unit to judge whether the audible and visual alarm module has started normally and decides to enter the forced warning stage or block the device start stage. The human-machine interaction module displays the status information in real time. Step S3: The steps to start the device. The sound and light alarm module starts normally. After the forced warning stage ends, the start request command takes effect and enters the preset countdown device start stage. The core control module determines whether the device has started successfully within the preset countdown. In some embodiments, in step S1, the core control module receives a device start request signal sent by the operator through the human-machine interaction module (by clicking the "Start Device" button on the human-machine interaction module), forcibly drives the relay output of the audible and visual alarm module to start the audible and visual alarm module, thus completing the linkage between the start request and the alarm trigger.

[0021] In step S2, the core control module determines whether the audible and visual alarm module is started normally. If the audible and visual alarm module is started abnormally, the core control module receives the abnormal startup information and blocks the device startup process, locking the device startup function. At the same time, the human-machine interaction module displays the abnormal startup of the audible and visual alarm module and the corresponding abnormal information. In some embodiments, if any fault occurs, the core control module will perform a blocking operation to prevent the device from starting, lock the device's start function (corresponding to the device's "emergency stop state" being locked), and at the same time display "Audio-visual alarm module startup abnormal" and its specific fault type on the interactive interface, while simultaneously flashing the "System alarm" prompt.

[0022] Among them, the abnormal start-up information of the sound and light alarm module includes power failure, sound alarm unit failure and light alarm unit failure. The power failure is that the power supply voltage or current of the sound and light alarm module exceeds the normal range. The sound alarm unit failure is that the buzzer, voice player, etc. do not emit alarm signals. The light alarm unit failure is that the strobe light, etc. do not generate light alarm signals. In some embodiments, if the power supply voltage or current exceeds the normal range, it is a power supply failure, and the core control module determines that the sound and light alarm module is abnormally activated; if the buzzer or voice player is not triggered, it is a sound alarm unit failure, and the core control module determines that "no alarm signal was issued"; if the strobe light does not light up, it is a light alarm unit failure, and the core control module determines that "no light signal was generated".

[0023] If the audible and visual alarm module starts normally, the core control module receives the normal start information and controls the audible and visual alarm module to enter the forced warning stage. At the same time, the human-machine interaction module displays that the audible and visual alarm module starts normally. At this time, the device is prohibited from starting. The mandatory warning phase is set to 2 minutes. In some embodiments, the core control module determines that the audible and visual alarm module has entered the 2-minute mandatory warning stage. At the same time, the interactive interface displays "Audible and visual alarm module started normally" and pops up a message "Mandatory warning in progress (2 minutes), device is prohibited from starting".

[0024] Example 4: like Figure 1 As shown, this embodiment of the invention provides a method for safe device startup, which specifically includes the following steps: Step S1: The step of sending the start request signal. The core control module receives the device start request signal sent by the operator through the human-machine interaction module and forcibly triggers the sound and light alarm module. Step S2: The step of judging the start status of the audible and visual alarm module. After the core control module receives the device start request and triggers the start of the audible and visual alarm module, it immediately collects its working status signal through the status detection unit to judge whether the audible and visual alarm module has started normally and decides to enter the forced warning stage or block the device start stage. The human-machine interaction module displays the status information in real time. Step S3: The steps to start the device. The sound and light alarm module starts normally. After the forced warning stage ends, the start request command takes effect and enters the preset countdown device start stage. The core control module determines whether the device has started successfully within the preset countdown. In some embodiments, in step S1, the core control module receives a device start request signal sent by the operator through the human-machine interaction module (by clicking the "Start Device" button on the human-machine interaction module), forcibly drives the relay output of the audible and visual alarm module to start the audible and visual alarm module, thus completing the linkage between the start request and the alarm trigger.

[0025] In step S2, the core control module determines whether the audible and visual alarm module is started normally. If the audible and visual alarm module is started abnormally, the core control module receives the abnormal startup information and blocks the device startup process, locking the device startup function. At the same time, the human-machine interaction module displays the abnormal startup of the audible and visual alarm module and the corresponding abnormal information. In some embodiments, if any fault occurs, the core control module will perform a blocking operation to prevent the device from starting, lock the device's start function (corresponding to the device's "emergency stop state" being locked), and at the same time display "Audio-visual alarm module startup abnormal" and its specific fault type on the interactive interface, while simultaneously flashing the "System alarm" prompt.

[0026] Among them, the abnormal start-up information of the sound and light alarm module includes power failure, sound alarm unit failure and light alarm unit failure. The power failure is that the power supply voltage or current of the sound and light alarm module exceeds the normal range. The sound alarm unit failure is that the buzzer, voice player, etc. do not emit alarm signals. The light alarm unit failure is that the strobe light, etc. do not generate light alarm signals. In some embodiments, if the power supply voltage or current exceeds the normal range, it is a power supply failure, and the core control module determines that the sound and light alarm module is abnormally activated; if the buzzer or voice player is not triggered, it is a sound alarm unit failure, and the core control module determines that "no alarm signal was issued"; if the strobe light does not light up, it is a light alarm unit failure, and the core control module determines that "no light signal was generated".

[0027] If the audible and visual alarm module starts normally, the core control module receives the normal start information and controls the audible and visual alarm module to enter the forced warning stage. At the same time, the human-machine interaction module displays that the audible and visual alarm module starts normally. At this time, the device is prohibited from starting. The mandatory warning phase is set to 2 minutes. In some embodiments, the core control module determines that the audible and visual alarm module has entered the 2-minute mandatory warning stage. At the same time, the interactive interface displays "Audible and visual alarm module started normally" and pops up a message "Mandatory warning in progress (2 minutes), device is prohibited from starting".

[0028] In step S3, if the device starts successfully within the preset countdown, the status information is transmitted to the core control module. The core control module controls the sound and light alarm module to turn off, and at the same time, the human-machine interaction module displays that the device has started normally. After the equipment starts up successfully, the core control module continuously monitors the equipment's operating status through the start-up detection unit. If an abnormality occurs during the equipment's operation, the core control module immediately controls the equipment to stop running and simultaneously drives the audible and visual alarm module to restart to issue a fault alarm. The human-machine interaction module simultaneously displays the abnormal equipment operation information and the cause. The preset countdown timer for device startup is set to 1 minute.

[0029] If the device fails to start or malfunctions during the preset countdown, the status information is transmitted to the core control module. The core control module automatically locks the device startup function and re-executes steps S1-S3.

[0030] In some embodiments, when the device startup phase is triggered, a "Device Startup Countdown (1 minute)" prompt appears on the interactive interface. If the device fails to start within the countdown, the core control module automatically locks the device startup function, and the interactive interface displays a "Startup failed, re-trigger startup process" prompt. The "System Alarm" area flashes alarm information. After that, the operator resends the device startup request signal to complete the audible and visual alarm linkage. After status detection, the startup is attempted again to achieve process closure.

[0031] Example 5: like Figure 2 As shown, the present invention provides a device safe start system, specifically including a central processing unit 1, an early warning module 2, a human-machine interaction module 3, and a device execution module 4; The central processing unit 1 is used to receive the device start request signal sent through the human-machine interaction module 3 and control the early warning module 2 and the device execution module 4 to perform corresponding operations. The early warning module 2 is used to issue early warnings based on the operation instructions given by the central processing unit 1; The human-computer interaction module 3 interacts with the central processing unit 1 to display status information in real time; The device execution module 4 executes the device startup procedure according to the corresponding instructions from the central processing unit 1.

[0032] The central processing unit 1 receives the equipment start request signal sent by the operator through the human-machine interaction module 3, and determines whether the warning module 4 has started normally. If the warning module 2 starts abnormally, the central processing unit 1 receives the start abnormal information and blocks the equipment start process, locking the equipment execution module 4. At the same time, the human-machine interaction module 3 displays the start abnormality of the warning module 2 and the corresponding abnormal information. If the warning module 2 starts normally, the central processing unit 1 receives the start normal information and controls the warning module 2 to enter the forced warning stage. At the same time, the human-machine interaction module 3 displays that the warning module 2 has started normally. At this time, the equipment is prohibited from starting. Among them, the human-computer interaction module 3 adopts a visual interactive interface for intelligent belt protection; For example, the central processing unit 1 receives the equipment start request signal sent by the operator through the intelligent belt protection visual interactive interface (by clicking the "Start Equipment" button on the interactive interface), forcibly drives the relay output of the early warning module 2, causing the early warning module 2 to start (the "Emergency Stop Early Warning" and "System Alarm" in the interactive interface are associated with the sound and light devices), thus completing the linkage between the start request and the alarm trigger.

[0033] For example, if any fault occurs, the central processing unit 1 will execute a device startup blocking operation, lock the device startup function (corresponding to the device's "emergency stop state" linkage lock), and at the same time display "Audio-visual alarm module startup abnormal" and its specific fault type on the belt intelligent protection visual interactive interface, and simultaneously flash "System alarm" prompt.

[0034] After the mandatory warning phase ends, the device start request command takes effect and enters the preset countdown device start phase. If the device starts successfully within the preset countdown, the status information is transmitted to the central processing unit 1. The central processing unit 1 controls the warning module 2 to shut down. At the same time, the human-machine interaction module 3 displays that the device has started normally. After the device starts successfully, the central processing unit 1 continues to monitor the device's operating status. If an abnormality occurs during the device's operation, the central processing unit 1 immediately controls the device to stop running and drives the warning module 2 to restart to issue a fault alarm. The human-machine interaction module 3 simultaneously displays the device's abnormal operation information and the cause. If the device fails to start or malfunctions during the preset countdown, the status information is transmitted to the central processing unit 1. The central processing unit 1 automatically locks the device startup function and performs monitoring and warning again. The mandatory warning phase is set to 2 minutes, and the preset countdown device activation phase is set to 1 minute.

[0035] For example, the central processing unit 1 determines that the early warning module 2 has entered the 2-minute mandatory early warning stage. At the same time, it displays "Early warning module 2 starts normally" on the intelligent belt protection visualization interface and pops up the message "Mandatory early warning in progress (2 minutes), equipment is prohibited from starting".
