Abstract
Description
Technical Field
[0001] This utility model relates to the field of road monitoring technology, and more specifically, to an integrated device for remote monitoring and communication of highways. Background Technology
[0002] The integrated remote monitoring and communication device for highways combines two important functions: monitoring and communication. It can acquire various information on highways in real time, such as traffic flow, vehicle status, and road conditions. Installing this device on key sections of highways allows for accurate traffic volume statistics, helping traffic management departments to promptly identify congested areas and implement traffic control measures. Especially during peak travel periods like holidays, by monitoring vehicle traffic volume on different sections, it enables advance planning of diversion routes to prevent large-scale traffic paralysis.
[0003] However, existing integrated remote monitoring and communication devices for highways have some problems. In some remote mountainous sections of highways, due to the complex geographical environment, traditional wireless communication networks often cannot provide effective coverage. This makes it difficult to transmit traffic data and monitoring images collected by the devices in a timely manner, resulting in the monitoring center being unable to obtain accurate information about these sections in a timely manner, adversely affecting the overall control of highway traffic conditions. Furthermore, severe weather conditions, such as heavy rain, heavy snow, and dense fog, can also affect the device's communication. These weather conditions may weaken the wireless signal strength and increase signal attenuation, thus preventing data from being transmitted in a timely and complete manner.
[0004] Therefore, it is of great significance to find a solution to the problem that existing highway remote monitoring and communication integrated devices cannot transmit monitoring data in remote mountainous areas and in severe weather. Utility Model Content

Pin 5 of relay U1, pin 1 of OR gate U2, one end of capacitor C1, and pin 2 of counter U5 are connected. Pin 4 of relay U1, pin 2 of XOR gate U4, pin 4 of XOR gate U4, and pin 1 of AND gate U6 are connected. Pin 2 of OR gate U2 and pin 4 of XOR gate U3 are connected. Pin 3 of OR gate U2 is grounded, and pin 5 is connected to the power supply. Pin 4 of OR gate U2, pin 1 of XOR gate U3, pin 4 of OR gate U7, and pin 1 of counter U5 are connected. Pin 5 of XOR gate U3 is connected to the power supply. Pin 2 of XOR gate U3 is connected to the cathode of diode D1.

[0047] It should be noted that the CO_IN1 input terminal is connected to the CTS pin of communication module one, and the CO_IN2 input terminal is connected to the CTS pin of communication module two; the CO_IN3 and CO_IN4 input terminals are connected to the V20 and W20 pins of the FPGA processor, respectively; and the CO_OUT1 and CO_OUT2 output terminals are connected to the Y18 and Y19 pins of the FPGA processor, respectively.
[0048] It should be noted that the model of relay U1 is SRD-12VDC-SL-C; the models of OR gate 1 U2 and OR gate 2 U7 are both 74LVC1G32GW; the models of XOR gate 1 U3 and XOR gate 2 U4 are both 74LVC1G86GV; the model of AND gate U6 is SN74AHC1G08DBVR; and the model of counter U5 is 74LS161.
[0049] The workflow of the judgment module is as follows:
[0050] The judgment module determines whether communication module one has failed to send data within a specified number of attempts. If data is not successfully sent, the CO_IN1 input terminal receives a high level, and the counter U5 counts the number of attempts. When the counter U5 counts that the number of times communication module one has failed to send data has reached the specified number, the CO_OUT1 output terminal outputs a control signal to the processing module, and the processing module switches to the transmission channel of communication module two for video data transmission.
[0051] The judgment module determines whether communication module 2 has failed to send data within a specified number of attempts. If data is not successfully sent, the CO_IN2 input terminal receives a high level, and the counter U5 counts the number of attempts. When the counter U5 counts that the number of times communication module 2 has failed to send data has reached the specified number, the CO_OUT1 and CO_OUT2 output terminals simultaneously output control signals to the processing module, and the processing module switches to the transmission channel of the buffer module for video data transmission.
[0052] It needs to be explained that capacitor C1 is used for delay, so that OR gate U2 first judges and outputs a high level to counter U5, so that counter U5 keeps counting, and then pin 2 of counter U5 receives the pulse signal.
[0053] The working process of this device is as follows:
[0054] The camera module transmits the video footage captured on the highway to the processing module. The processing module encodes the video and converts it into a format suitable for transmission by the communication module before transmitting it to communication module one. If the judgment module determines that communication module one has failed to send data within a specified number of attempts, the judgment module sends an electrical signal to the processing module. The processing module then switches the data transmission channel, stopping data transmission to communication module one and starting data transmission to communication module two. Similarly, if the judgment module determines that communication module two has failed to send data within a specified number of attempts, the judgment module sends an electrical signal to the processing module. The processing module then switches the data transmission channel, stopping data transmission to both communication modules one and two and starting data transmission to the buffer module.
[0055] In some embodiments, an alarm module is also provided, which includes a GSM module. When the judgment module determines that both communication module one and communication module two have failed to send data within a specified number of attempts, the judgment module sends a control signal to the GSM module, and the GSM module sends an alarm signal to the monitoring terminal to notify the staff to pay attention.
[0056] It should be noted that all of the above-mentioned electronic components are available on domestic and international markets.
