Description

Technical Field

[0001] This invention relates to a monitoring system, and more particularly to an electronic lifting pile status monitoring system, belonging to the field of security equipment monitoring technology. Background Technology

[0002] Electronic bollards are key equipment for managing vehicle traffic and protecting areas. The reliability of their working status is of paramount importance. Currently, the common monitoring method is to judge the motor current of a single bollard or a single sensor. This method cannot quickly and intuitively monitor the overall status of a group of bollards.

[0003] If a bollard fails to descend to its designated position due to mechanical jamming, insufficient power, or control system malfunction, and this is not detected in time, it will create a security loophole and pose a safety hazard. Existing technologies lack a multi-point status monitoring solution that is simple in structure, low in cost, responds instantly, and can simultaneously drive local audible and visual alarms and remote status displays.

[0004] Therefore, it is urgent to improve the monitoring system for the status of electronic lifting piles in order to solve the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this invention is to provide an electronic lifting pile status monitoring system. The core logic judgment module uses common multi-input NOR gate logic chips, requires no software intervention, has a fast response and stable operation, and can easily expand the number of monitoring units. The local alarm execution module uses a simple circuit to realize audible and visual alarms, and the remote status display module can display the overall status of the lifting pile in real time in a remote monitoring room. Text information makes it easy for monitoring personnel to quickly understand the situation, thus improving overall management efficiency and system reliability.

[0006] The main technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: An electronic bollard status monitoring system includes: The signal acquisition module includes several normally open trigger switches installed at the bottom of the corresponding electronic lifting piles, which are used to acquire the descent status signal of each lifting pile. The core logic judgment module has its input ports connected to all normally open trigger switches. It is used to perform logical operations on the status signals of all normally open trigger switches and output a total status judgment signal. The local alarm execution module is connected to the output of the core logic judgment module and is used to generate corresponding audible and visual alarm indications based on the status judgment signal. The remote status display module is connected to the output of the core logic judgment module and is used to display the overall working status of all lifting piles in a remote monitoring room.

[0007] Furthermore, the core logic judgment module includes a multi-input NOR gate logic chip. One end of the normally open trigger switch is grounded, and the other end is connected to the positive terminal of the DC power supply through pull-up resistors R1-R9, and is respectively connected to each input pin of the multi-input NOR gate logic chip. The output pin level of the multi-input NOR gate logic chip is the status judgment signal.

[0008] Furthermore, the local alarm execution module includes: A dual-color light-emitting diode, comprising a green LED and a red LED, wherein the cathode of the green LED is connected to the output pin of the multi-input NOR gate logic chip through a first current-limiting resistor R9, and the cathode of the red LED is electrically connected to an inverter, and is connected to the output pin of the multi-input NOR gate logic chip through the inverter; An alarm horn is electrically connected to an NPN transistor switch driver circuit, which is connected to the output pin of a multi-input NOR gate logic chip through a second current-limiting resistor R10. When the output pin is at a high level, the green LED of the dual-color light-emitting diode is working, and the alarm horn is not working; When the output pin is at a low level, the red LED of the dual-color light-emitting diode is activated, and the alarm horn is activated.

[0009] Furthermore, the remote status display module includes a display controller and a monitoring display screen that are electrically connected. The input port of the display controller is connected to the output pin of a multi-input NOR gate logic chip, and is used to display the text information "lifting pile is working normally" or "lifting pile is malfunctioning" on the control display screen according to the high or low level of the output pin.

[0010] Furthermore, the multi-input NOR gate logic chip is model CD4078 or MC14078.

[0011] Furthermore, the normally open trigger switch is a micro switch or a magnetic proximity switch.

[0012] Furthermore, the display terminal of the remote status display module is an LED screen or a display terminal connected to the computer in the guard room.

[0013] A method for monitoring the status of electronic bollards includes: System initialization steps include powering each module; The status acquisition step involves real-time acquisition of the on / off status of the normally open trigger switches at the bottom of each electronic lifting pile; The logical judgment step involves inputting the collected states of all normally open trigger switches into a multi-input NOR gate logic chip for logical operations. The output step is executed, and the sound and light status of the local alarm and the text display status of the remote display screen are controlled according to the output result of the multi-input NOR gate logic chip. Return to the previous step and repeat the status acquisition step until the output step is executed.

[0014] Furthermore, the logical judgment steps are specifically as follows: If all normally open trigger switches are closed, all inputs of the multi-input NOR gate logic chip will be low and the output will be high. If one or more normally open trigger switches are open, the corresponding input of the multi-input NOR gate logic chip will be high and the output will be low.

[0015] Furthermore, the execution output step specifically includes: If the output is high, the green LED indicator will light up, the alarm horn will be turned off, and "Working normally" will be displayed on the remote display screen. If the output is low, the red LED indicator light will illuminate, the alarm horn will be activated, and "Operating Fault" will be displayed on the remote display screen.

[0016] The present invention has the following beneficial effects: 1. The signal acquisition module adopts a normally open trigger switch, which is easy to install, has a low failure rate, and can work stably in harsh environments. It accurately acquires the descent status signal of the lifting pile. The core logic judgment module uses common multi-input NOR gate logic chips, which do not require software intervention. It has a fast response and stable operation and can easily expand the number of monitoring units. The local alarm execution module uses a simple circuit to realize audible and visual alarms. The remote status display module can display the overall status of the lifting pile in real time in the remote monitoring room. Text information makes it easy for monitoring personnel to quickly understand the situation, thus improving management efficiency and system reliability. 2. The system is divided into five independent steps: system initialization, status acquisition, logic judgment, execution output, and return. Each module has a single and clear function, which facilitates development, debugging, and maintenance. The system process achieves real-time and reliable monitoring of the electronic lifting pile status through modular design, hardware logic judgment, and closed-loop execution mechanism. It has the advantages of low cost, strong scalability, and good anti-interference ability. It is especially suitable for industrial scenarios with high requirements for safety and response speed. Its core advantage lies in solving complex status monitoring problems with simple hardware logic, while taking into account user experience and maintenance convenience. Attached Figure Description

[0017] Figure 1 This is a schematic diagram of the electrical principle structure of the present invention; Figure 2 This is the circuit diagram of the present invention. Detailed Implementation

[0018] The technical solution of the present invention will be further described in a non-limiting manner below with reference to the accompanying drawings and specific embodiments.

[0019] like Figures 1-2 As shown, the electronic lifting pile status monitoring system provided in this embodiment includes: The signal acquisition module includes several normally open trigger switches installed at the bottom of the corresponding electronic lifting piles. These normally open trigger switches are either micro switches or magnetic proximity switches, both of which are common types of trigger switches. The system can be flexibly selected according to actual needs, improving its applicability and enabling stable operation in various harsh environments. One end of each normally open trigger switch is grounded, and the other end is connected to the positive terminal of a DC power supply through pull-up resistors R1-R9. By installing trigger switches at the bottom of each lifting pile, the system can acquire the descent status signal of each lifting pile. The signal is accurate and reliable. The normally open trigger switches have a simple structure, are easy to install, have a low failure rate, and are easy to maintain.

[0020] The core logic judgment module has its input ports connected to all normally open trigger switches. It is used to perform logical operations on the status signals of all normally open trigger switches and output a total status judgment signal. The core logic judgment module includes a multi-input NOR gate logic chip, which is either CD4078 or MC14078. These are common multi-input NOR gate logic chips with stable and reliable performance, suitable for various industrial environments. The chips are widely available on the market, easy to purchase and replace, and reduce the system maintenance cost. Normally open trigger switches are connected to the various input pins of the multi-input NOR gate logic chip. The output pin level of the multi-input NOR gate logic chip is the status judgment signal. Using a multi-input NOR gate chip, there is no software or firmware involved, avoiding the risk of program crashes or errors. It has a fast response speed and stable operation. The logic function of "alarm if any switch is not closed" is implemented through the multi-input NOR gate logic chip. The logic is clear and easy to understand. In addition, it can be easily expanded to monitor more lifting piles to meet the application needs of different scales.

[0021] The local alarm execution module is connected to the output of the core logic judgment module and is used to generate corresponding audible and visual alarm indications based on the status judgment signal.

[0022] The local alarm execution module includes: The dual-color LED includes a green LED and a red LED. The cathode of the green LED is connected to the output pin of a multi-input NOR gate logic chip through a first current-limiting resistor R9. The cathode of the red LED is electrically connected to an inverter, which is also connected to the output pin of the multi-input NOR gate logic chip. An alarm horn is electrically connected to an NPN transistor switch driver circuit, which is connected to the output pin of the multi-input NOR gate logic chip through a second current-limiting resistor R10. This simple NPN transistor switch driver circuit and inverter are used to switch the LEDs and control the alarm horn. The green and red LEDs and the alarm horn provide on-site audible and visual alarm indications, allowing operators to quickly detect any abnormalities in the lifting pile's status. The circuit structure is simple and inexpensive.

[0023] When the output pin is high, the green LED of the dual-color LED is on, and the alarm horn is off. When the output pin is low, the red LED of the dual-color LED is on, and the alarm horn is on. The high level only illuminates the green LED and the alarm horn is off, which is suitable for quiet environments under normal conditions. The low level illuminates the red LED and the alarm horn is on, which is suitable for a conspicuous warning in emergency situations and avoids unnecessary noise interference. By switching between the green and red LEDs, operators can intuitively and quickly judge the system status. The green LED indicates "normal" and the red LED indicates "fault", which is consistent with common sense and reduces the possibility of misjudgment. When the red LED light illuminates, the alarm horn also activates, providing both visual and auditory alerts to ensure that operators can quickly notice any abnormalities. This combined sound and light alarm method is particularly reliable in noisy environments.

[0024] The remote status display module, connected to the output of the core logic judgment module, is used to display the overall working status of all lifting piles in a remote monitoring room. This allows for real-time viewing of the overall working status of the lifting piles from the guard room or other monitoring centers, improving management efficiency. The remote status display module includes an electrically connected display controller and a monitoring display screen. The input port of the display controller is connected to the output pin of a multi-input NOR gate logic chip, controlling the display screen to show the text message "Lifting pile working normally" or "Lifting pile malfunctioning" based on the high or low level of the output pin. By displaying "working normally" or "malfunctioning" text messages on the screen, monitoring personnel can quickly understand the status of the lifting piles, facilitating timely handling of abnormal situations. The display terminal of the remote status display module can be an LED screen or a display terminal connected to the computer in the guard room, allowing for flexible selection based on actual needs and improving system applicability. Therefore, the signal acquisition module adopts a normally open trigger switch, which is easy to install, has a low failure rate, and can work stably in harsh environments, accurately acquiring the descent status signal of the lifting pile. The core logic judgment module uses common multi-input NOR gate logic chips, without software intervention, with fast response and stable operation, and can easily expand the number of monitoring units. The local alarm execution module uses a simple circuit to realize audible and visual alarms, and the remote status display module can display the overall status of the lifting pile in real time in the remote monitoring room. Text information makes it easy for monitoring personnel to quickly understand the situation, thus improving overall management efficiency and system reliability.

[0025] like Figures 1-2 As shown, the electronic lifting pile status monitoring method provided in this embodiment includes: System initialization steps include powering each module; The status acquisition step involves real-time acquisition of the on / off status of the normally open trigger switches at the bottom of each electronic lifting pile, enabling the system to detect changes in the position of the lifting pile immediately. The logical judgment step involves inputting the collected states of all normally open trigger switches into a multi-input NOR gate logic chip for logical operations. The logical judgment steps are as follows: If all normally open trigger switches are closed, all inputs of the multi-input NOR gate logic chip will be low and the output will be high. If one or more normally open trigger switches are open, the corresponding input of the multi-input NOR gate logic chip will be high and the output will be low. The output step is executed, and the sound and light status of the local alarm and the text display status of the remote display screen are controlled according to the output result of the multi-input NOR gate logic chip. The specific steps for executing the output are as follows: If the output is high, the green LED indicator will light up, the alarm horn will be turned off, and "Working normally" will be displayed on the remote display screen. If the output is low, the red LED indicator will light up, the alarm horn will be activated, and "Working Fault" will be displayed on the remote display screen. Through the real-time feedback of the local green and red LEDs and the remote display screen, the faulty lifting pile can be quickly located, shortening the maintenance time. The remote display screen can store status change records to provide data support for subsequent analysis. Return to the previous step and repeat the status acquisition step until the output step is executed. The system is divided into five independent steps: system initialization, status acquisition, logic judgment, execution output, and return. Each module has a single and clear function, which facilitates development, debugging, and maintenance. Through modular design, hardware logic judgment, and closed-loop execution mechanism, the system achieves real-time and reliable monitoring of the electronic lifting pile status. It has the advantages of low cost, strong scalability, and good anti-interference ability. It is especially suitable for industrial scenarios with high requirements for safety and response speed. Its core advantage lies in solving complex status monitoring problems with simple hardware logic, while taking into account user experience and maintenance convenience.
