[0025] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0026] like Figure 1 , 2 As shown in Figures 3 and 4, this embodiment provides a port channel safety fence warning system, which includes a cylindrical box 1 and a main control board 2. The main control board 2 is arranged inside the upper end of the cylindrical box 1. A plurality of water target detection modules 3 are evenly arranged on the outer wall of the upper end of the cylindrical box 1, and a plurality of underwater target detection modules 4 are evenly arranged on the outer wall of the lower end of the cylindrical box 1. When in use, the lower end of the cylindrical box 1 is placed below the water surface.

[0027] like Figure 4 As shown, the main control board 2 of this embodiment includes an MCU module and an alarm module, and the above-water target detection module 3, the underwater target detection module 4 and the alarm module are electrically connected to the MCU module respectively.

[0028] like Figure 5 As shown, the MCU module of this embodiment adopts the MCU chip U1 of model STC12C5A60S2, which has a large-capacity program storage, a built-in integrated MAX810 dedicated reset circuit and 2-way PWM waves. The power supply voltage of the MCU chip U1 is between 5.5V and 3.3V, which is a low-power and high-running control chip. STC12C5A60S2 has a total of 40 pins, of which 32 IO port pins are classified as P0, P1, P2, and P3, with a total of 4 groups of ports, and each group of ports is further subdivided into 8 pins. Among these 32 pins, P3.0 and P3.1 pins are commonly used, which can send and receive data; P3.2 and P3.3 pins are external interrupt pins. Among the other 8 pins, RST is the reset pin, XTAL2 and XTAL1 are clock signal pins, VSS and VCC are power pins, and RST2 is the external ROM selection terminal. The clock signal input terminal T1, the clock signal output terminal T2, the external crystal oscillator, the two capacitors and the internal oscillation circuit form a complete crystal oscillator circuit. The capacitor is generally selected between 10pf and 50pf, and the 20P capacitor is the best. The role of these two capacitors is to assist the crystal oscillator in starting, which is beneficial to the stability of the internal oscillator of the MCU chip U1.

[0029] like Figure 5As shown, the water target detection module 3 of this embodiment adopts an infrared obstacle avoidance sensor U2, model E18-D80NK, which is used to detect whether there is a ship entering the waterway. E18-D80NK is also called a diffuse reflection photoelectric switch device, and its working principle is: when the emitter on the device detects the target object, it will continue to emit infrared rays, and the emitted infrared rays are transmitted back and received by the receiving tube, which converts the infrared rays into electrical signals after receiving them and transmits them to the MCU chip U1.

[0030] like Figure 5 As shown, the underwater target detection module 4 of this embodiment adopts an ultrasonic sensor U3, which is used to obtain ship signals from under the water surface of the port channel, and can detect the distance signal of the ship. The model of the ultrasonic sensor U3 is HC-SR04, which has a wide operating voltage, in the input range of 3V to 5.5V, stable performance, high measurement accuracy, reaching 1mm accuracy, static power consumption less than 2mA, and comes with temperature sensor compensation, which can correct the ranging error. The sensing angle is not more than 15 degrees, and it has multiple communication modes such as serial port and GPIO, as well as performance such as watchdog, which greatly improves the stability of the device operation, and the detection distance is 2cm to 450cm away. The 4 pins of ultrasonic 2 are led out, VCC, GND, E and T. The power pins VCC and GND pins of the ultrasonic sensor U3 are respectively connected to the positive and negative poles of the 5V power supply, and the E and T signal control pins are respectively connected to the P0.1 and P0.0 pins of the MCU chip U1.

[0031] like Figure 4 As shown, the alarm module of this embodiment is used to give an alarm prompt when a ship intrudes into the port channel. The alarm module includes a remote alarm module, a voice alarm prompt module and a buzzer. The remote alarm module, the voice alarm prompt module and the buzzer are electrically connected to the MCU module respectively.

[0032] The remote alarm module is used to send an alarm message to the port monitoring center when a ship intrudes into the port channel. Figure 5As shown, the remote alarm module is a GSM communication module. The signal of the GSM communication module U4 is sim900A, which supports SMS, data, Internet access and other functions. Through the TTL level serial port adaptive connection, it can be directly connected to the MCU chip U1, or it can be connected to the computer through a 232USB serial port line. There are 4 access pins of sim900A, the positive and negative poles of the power supply and the communication input and output pins, among which the TXD pin is connected to the P1.2 pin of the MCU chip U1, and the RXD pin is connected to the P1.3 pin of the MCU chip U1. The GSM communication module U4 first needs to insert a mobile phone sim card, initialize the IO port of the MCU chip U1 corresponding to the GSM communication module, and first set the baud rate, set the timer mode, and set the interrupt to ensure that the text message is sent out. Then enter the serial port interrupt, and then start the timer, and the text message can be sent after a certain period of time.

[0033] The voice alarm prompt module is used to give a voice broadcast prompt to the intruding ship when a ship breaks into the port channel, and to give a voice prompt to the personnel on the intruding ship to leave the channel. Figure 4 As shown, the voice alarm prompt module includes a voice broadcast module and a speaker, the input end of the voice broadcast module is electrically connected to the MCU module, and the output end of the voice broadcast module is electrically connected to the speaker. Figure 5 As shown, the model of the voice broadcast module U5 here is MP3-TF-16P. The MP3-TF-16P is used to decode the terminology and then transmit it to the speaker, which then broadcasts it. The voice broadcast module U5 is equipped with a card slot, which allows the memory card to be freely inserted and removed. The volume of the voice can be flexibly adjusted when playing the voice. The file format supports audio decoding of ISO138 13-3 Layer and supports sound effects such as POP and POCK. There are three types of UART interfaces, namely, one-line serial port, standard serial port, and TTL serial port. In addition, the specified voice is broadcasted through the voice broadcast module U5, and the serial port data communication between the voice broadcast module U5 and the MCU chip U1 is realized by AT commands. The AT command sent by the voice broadcast module U5 needs to go through a certain sequence process to realize the terminology broadcast function.

[0034] The buzzer is used to sound an alarm when a ship enters the port channel. Figure 5As shown, the buzzer is an active buzzer, which is an integrated long acoustic electromagnetic electronic sounder. It integrates multiple chip integrated circuits inside, and the integrated circuits are welded with gold wire balls, which are resistant to high temperatures and have stable performance. When powered by a DC power supply, the device can emit a monotonous chirping sound. The buzzer U6 is connected to the MCU chip U1, and the required current is relatively large. Therefore, a transistor Q1 is connected to the branch between the buzzer U6 and the MCU chip U1 to protect the buzzer U6. The conduction of the buzzer U6 and the sound can be achieved by outputting a low level at the IO port of the MCU chip U1. If the buzzer U6 needs to be turned off, the IO port of the MCU chip U1 can output a high level.

[0035] The specific embodiments described above further illustrate the technical problems, technical solutions and beneficial effects solved by the present invention. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
