Description

Technical Field

[0001] This utility model relates to the field of abnormal monitoring and control technology of highway lane equipment, and specifically to a centralized monitoring system for highway lanes. Background Technology

[0002] With the complete removal of provincial toll stations on national highways, the Electronic Toll Collection (ETC) system has seen unprecedented adoption, occupying the vast majority of all lanes and significantly improving traffic efficiency, reducing repetitive manual labor, and lowering operating costs. However, in actual operation, ETC lanes occasionally experience issues such as barriers failing to lower for extended periods, unlicensed drivers slowly ramming the barriers to evade tolls, and ETC-related issues (e.g., blacklisted cards, lack of electronic tags). The former affects normal toll collection, while the latter impacts lane efficiency and overall throughput. Due to the large number of lanes at toll stations, field staff often cannot detect and handle these anomalies immediately, or some alarm devices only address specific aspects of the problem locally, which is less effective in noisy toll stations with heavy traffic. Therefore, it is necessary to design a centralized lane monitoring system to centrally monitor various anomalies. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1: Figure 1This is a schematic diagram of the overall circuit structure of this utility model. A centralized monitoring system for highway lanes mainly consists of a barrier gate 14, a barrier gate anomaly detection and alarm device 11, a toll display 15, an ETC emergency detection and prompting device 12, a canopy signal light 16, a canopy signal light distribution device 13, and a centralized terminal 10. The barrier gate anomaly detection and alarm device 11 is responsible for collecting signals of barrier gate failure, barrier violation, local alarm prompts, and sending remote alarm signals. This device has two inputs: one is connected to the feedback signal in the main board of the barrier gate 14 to collect whether the barrier gate is in a vertical or horizontal state; the other is a proximity switch fixed on the upper side of the barrier arm of the barrier gate 14 to determine whether the barrier has fallen off. When the barrier gate anomaly detection and alarm device 11 detects that the barrier has been in a vertical state for a long time or that the proximity switch has a momentary signal, it determines that there is a barrier failure or a vehicle violation, and will issue a high-pitched alarm locally and send it to the centralized terminal 10 via wireless signal to prompt field personnel to check and handle the situation in a timely manner. The ETC emergency detection and alert device 12 is responsible for collecting ETC transaction failure information, providing local alarm alerts, and sending remote alarm signals. Its signal input terminal is connected to the signal input terminal of the toll display 15, i.e., the serial port signal output from the lane control computer. It synchronously collects and analyzes the serial port signal input to the toll display 15 in real time. If an emergency is detected, such as a blacklisted card or no electronic tag, a local alarm is triggered and a prompt voice is played. Simultaneously, the alarm is wirelessly transmitted to the centralized terminal 10, prompting field personnel to intervene promptly. The canopy traffic light issuing device 13 is responsible for controlling the local issuance and receipt of control commands from the centralized terminal. Its input signal is the wireless signal emitted by the centralized terminal 10. By real-time detection, collection, and analysis of the signals from the centralized terminal 10, it enables remote issuance of commands to the canopy traffic lights 16. The centralized terminal 10 is responsible for unified collection and analysis, alarm prompts and remote control. Its inputs are alarm signals issued by the barrier gate abnormality detection alarm device 11 and the ETC special situation detection prompt device 12, as well as manual operations. Its outputs are voice prompts and control signals issued by the canopy signal lights.

[0019] Example 2: Figure 2 This is a schematic diagram of the circuit structure of each module of this utility model.

[0020] A centralized monitoring system for lane anomalies at highway toll stations mainly consists of a barrier gate 14, a barrier gate anomaly detection and alarm device 11, a toll display 15, an ETC emergency detection and prompting device 12, a canopy signal light 16, a canopy signal light distribution device 13, and a centralized terminal 10. It is further composed of a feedback signal acquisition module A113, a main controller A114, a TTL to RS232 converter module A111, a local alarm circuit module A112, an Internet of Things (IoT) LoRa module A115, a proximity switch 116, and a signal conversion module A117. The feedback signal acquisition module A113 is connected to the feedback signal input of the barrier gate 14 and to the general I / O port of the main controller A114. It is used to collect whether the barrier is vertical or horizontal. When the barrier is vertical for more than a certain period of time, it indicates that the barrier gate may not be lowering. Then the main controller A114 will send a control signal. The control signal is converted into an RS232 signal by the TTL to RS232 module A111 and then controls the local alarm circuit module A112 to provide a local alarm prompt. At the same time, it controls the IoT LoRa module A115 to send a signal to the central terminal 10 through the serial port. The proximity switch 116 is fixed at a suitable position on the barrier arm of the barrier mechanism 14 to detect whether the barrier has detached from the barrier arm. When an attempt to breach the barrier occurs, the barrier will detach from the barrier arm, and this signal will be captured by the proximity switch 116. Subsequently, the 12V proximity switch output signal is converted into a normal switch signal that can be acquired by the main controller A114 through the signal acquisition module B123. The main controller A114 will also send another control signal, which is also converted into an RS232 signal by the TTL to RS232 converter A111 and then controls the local alarm circuit module A112 to provide a local alarm prompt. At the same time, it controls the IoT LoRa module A115 to send a signal to the central terminal 10 via the serial port. In order to distinguish different alarm situations, the local alarm circuit module A112 will play different alarm sounds according to the different control signals received. Similarly, the wireless signal emitted by the IoT LoRa module A115 should also carry different data information.

[0021] The ETC emergency detection and alert device 12 is responsible for collecting ETC transaction failure emergency information, providing local alarm alerts, and sending remote alarm signals. It consists of a signal acquisition module B123, a main controller B124, a TTL-to-RS232 module B121, a local alarm circuit module B122, and an IoT LoRa module B125. The signal acquisition module B123 is connected to the input RS232 signal of the toll display 15, meaning it simultaneously acquires signals from the lane control computer and converts the acquired signals into TTL signals. The main controller B124 collects and analyzes the data. When the main controller B124 detects special information, such as a blacklist card or no electronic tag, it sends a control signal. The control signal is converted into an RS232 signal by the TTL to RS232 module B121 and then controls the local alarm circuit module B122 to issue a local alarm prompt. At the same time, it controls the IoT LoRa module B125 to send a signal to the central terminal 10 via the serial port. Similarly, the local alarm circuit module B122 should play different prompt sounds for different special information.

[0022] The rain shelter signal light sending device 13 is responsible for controlling the rain shelter signal light 16 to send and receive control commands from the centralized terminal. It consists of a main controller C131, an IoT LoRa module C132, and a button module 133. The main controller C131 acts as the host, directly communicating with the rain shelter signal light 16 via serial port. The button module 133 controls the main controller C131 to send commands locally. The IoT LoRa module C132 receives signal commands from the centralized terminal 10 and controls the main controller C131 to send them. When the rain shelter signal light display needs to be changed, the user can manually operate it through the centralized terminal 10. The serial port screen 101 in the centralized terminal 10 will send a control signal, which is synchronously transmitted by the main controller C102 to the IoT LoRa module C103. The IoT LoRa module C103 then transmits the signal wirelessly to the IoT LoRa module C132, and the main controller C131 parses and sends a control signal to control the rain shelter signal light 16 to change its display.

[0023] The centralized terminal 10 is responsible for unified data collection and analysis, alarm notification, and remote control. It consists of a serial port screen 101, a main controller Z102, an IoT LoRa module Z103, and a voice playback module 104. The main controller Z102 is connected to the serial port screen 101, the IoT LoRa module Z103, and the voice playback module 104 via serial communication. When the IoT LoRa module Z103 receives an alarm signal, the main controller Z102 controls the serial port screen 101 to display it and simultaneously controls the voice playback module 104 to play a notification voice. When a user issues a command through the serial port screen 101, the main controller Z102 synchronously controls the IoT LoRa module Z103 to issue the command, and then the IoT LoRa module Z103 wirelessly transmits the control signal to a remote location.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
