[0048] Reference Figure 1 to Figure 2, the present invention provides a cable connection device 10 capable of intelligent monitoring, wherein corresponding ends of the cable connection device are electrically connected to a power distribution room and a charging pile respectively;

[0049] The cable connection device includes a locking component, an indicating component, a humidity monitoring component, a temperature monitoring component, a current monitoring component, a connection device plug 6, and a power supply cable socket 7 adapted to the connection plug;

[0050] The locking assembly is arranged on the connection device plug 6 and is used to lock the connection device plug 6;

[0052] The indicating component is used to indicate the connection status between the connecting device plug and the power supply cable socket;

[0053] The indicator component is a connection confirmation power light 2, and provides immediate visual feedback to inform the operator of the connection status between the connection device plug and the power supply cable socket.

[0054] The humidity monitoring component is used to monitor the humidity of the environment surrounding the cable connection device 10; by monitoring the humidity, damage or failure of electrical equipment caused by excessive humidity can be prevented, and by controlling the humidity, the risk of corrosion and electrical short circuits can be reduced, the service life of the equipment can be extended, and by preventing failures caused by humidity problems, the cost of repair and replacement of parts can be reduced.

The shell of the connecting device plug 6 has good insulation performance to prevent leakage and electric shock accidents.

[0058] Furthermore, the cable connection device 10 also includes a connection plug cover 8, which is arranged on the connection device plug 6 to protect the connection device plug from the external environment when not in use; protect the connection device plug 6 from the external environment such as dust, moisture, corrosive gas, etc., so as to extend the service life of the connection device plug 6 and maintain its good electrical connection performance; the connection plug cover 8 helps to reduce the wear and corrosion of the plug, thereby extending its service life. The connection plug cover 8 helps to keep the electrical contact parts of the connection device plug 6 clean and dry, and maintain its good electrical performance and connection reliability.

[0059] Furthermore, the cable connection device 10 also includes a resistance grip 9, which is arranged on the side of the connection device plug to provide a good grip and operating experience when plugging and unplugging the connection device plug, providing a stable grip point and sufficient friction, so that the operator can plug and unplug the plug more safely and conveniently; the design of the resistance grip 9 provides a comfortable gripping area, so that the operator feels better when plugging and unplugging the connection device plug 6, reducing hand fatigue; the resistance grip 9 reduces the risk of the plug slipping during the plugging and unplugging process, thereby reducing safety hazards during operation.

[0060] Furthermore, the connecting device plug 6 is connected to the three-phase incoming line terminal of the molded case circuit breaker of the charging pile through a cable, ensuring that the three-phase power can be stably transmitted to the charging pile. Through the three-phase power transmission, the stability and reliability of the power supply are improved, and the voltage imbalance problem that may be caused by single-phase or two-phase power supply is reduced; the power supply cable socket 7 is connected to the distribution room through a cable; when the connecting device plug 6 is plugged into the power supply cable socket 7, the pin of the connecting device plug 6 is inserted into the jack of the power supply cable socket 7.

[0061] Furthermore, the locking assembly includes an electronic lock 1, which is also provided with a position sensor for real-time monitoring of the status of the electronic lock, including whether it is locked or unlocked. By transmitting data from the position sensor to a remote monitoring platform, managers can remotely monitor the status of the electronic lock to achieve intelligent management.

[0062] Further, the indication component is set as a connection confirmation power light 2; the humidity monitoring component is set as a humidity resistor 3, the temperature monitoring component is set as a thermistor 4, and the current monitoring component is set as a shunt resistor 5; the charging pile is also provided with a control system; the control system is electrically connected to the corresponding ends of the electronic lock, the connection confirmation power light 2, the humidity resistor 3, the thermistor 4, and the shunt resistor 5 through a circuit breaker, and is used to control and monitor the working state of the cable connection device.

Through the connection with the circuit breaker, the control system can quickly cut off the power supply when an abnormal situation is detected to protect the safety of the equipment and users. The control system automatically executes corresponding control commands according to the collected data and the preset logic, such as adjusting the charging parameters or issuing an alarm. The real-time monitoring and rapid response capabilities of the control system significantly improve the safety of the charging pile and reduce the risk of electrical accidents. Automated control responses reduce the need for human intervention and improve the operating efficiency of the charging pile. By reducing the need for human monitoring and optimizing maintenance plans, the control system helps reduce the long-term operating costs of the charging pile. The control system can adapt to different working environments to ensure that the charging pile can operate reliably under various conditions.

[0063] The working principle of the present invention is as follows:

[0064] 1. Before the cable connection device 10 is activated: the electronic lock 1 is in a locked state. The electronic lock is equipped with a position sensor inside, which can monitor the state of the electronic lock in real time. The connection confirmation power light 2 is in standby and displays green when there is no abnormality, and red when there is an abnormality. The connection plug cover 8 is in a locked connection device plug state. The humidity resistor 3, the thermistor 4, and the shunt resistor 5 maintain real-time monitoring status and transmit it to the control system. If there is an abnormality, the connection confirmation power light 2 will display red.

[0065] 2. When the cable connection device 10 is enabled: when a signal indicating that the charging pile needs to be powered is received, the connection plug cover 8 is unlocked, the connection confirmation power light 2 is observed to be green, the electronic lock 1 buckle is pressed to open the connection device plug cover 8, and the connection device plug 6 is inserted into the power cable socket 7 to ensure that the plug is inserted in place and has good contact. At this time, the connection confirmation power light 2 should flash green to indicate a successful connection. If the connection confirmation power light 2 is always green, check whether the connection device plug 6 and the power cable socket 7 are connected in place and whether the power supply is normal; start the charging pile and start charging operation. When the shunt resistor 5 detects the current output, the connection confirmation power light (2) is always yellow. During the charging process, the humidity-sensitive resistor 3 and the thermistor 4 will monitor the ambient humidity and the temperature of the connection device in real time. If the humidity or temperature exceeds the set value, the charging pile will automatically stop charging and issue an alarm. The shunt resistor 5 will measure the charging current in real time to monitor and manage the charging process.

[0066] 3. After the cable connection device 10 is activated: When charging is completed, stop the charging operation of the charging pile first. When the shunt resistor 5 detects that there is no current output, the connection confirmation power light 2 will flash green. After confirmation, disconnect the power supply cable device socket 7 and the connection device plug (6); the connection confirmation power light 2 will be always green. Cover the connection device plug cover 8 to protect the plug from external factors such as dust and moisture, and the electronic lock (1) is in the locked state. The humidity-sensitive resistor 3, the thermistor 4, and the shunt resistor 5 maintain real-time monitoring status and transmit it to the control system. If there is any abnormality, the connection confirmation power light 2 will be red.

[0067] The present invention also provides a method for using an intelligent monitoring cable connection device, comprising the following steps:

[0068] Step a: Open the electronic lock, connect the connection device plug 6 with the power supply cable socket 7, and check whether the connection is abnormal by connecting the power light 2; the operator can immediately know whether the connection is successful, which improves the accuracy and efficiency of the operation; by detecting the connection abnormality, equipment damage or safety hazards caused by incorrect connection can be avoided.

[0069] Step b: If the connection is successful, proceed to the next step; if the connection fails, the control system receives the signal and uploads the abnormal information to the remote monitoring platform to remind the personnel to check and repair; when the connection fails, it can respond quickly to reduce the equipment failure time and improve the reliability of the system; timely discover and repair problems to avoid safety accidents caused by poor connection;

[0070] Step c: monitor and analyze the electronic lock status, humidity, temperature and current transmission signals generated by the electronic lock, humidity-sensitive resistor 3, thermistor 4 and shunt resistor 5 in real time through the control system, and judge whether the working status of the connection device is normal according to the preset parameters and logic; through real-time monitoring, timely discover potential safety hazards, such as excessive humidity, abnormal temperature or excessive current; adjust the equipment operating parameters according to the monitoring results, optimize the equipment performance and extend the service life;

[0071] Step d: When an abnormal working status is detected, the control system takes corresponding measures, including sounding an alarm, cutting off the power supply, and adjusting the charging parameters to ensure the safe operation of the charging pile and the safety of the user, and uploads the working status information to the remote monitoring platform to facilitate managers to monitor and manage the operation of the charging pile in real time; by automatically taking emergency measures, the equipment and users are protected from harm; managers can monitor the equipment status in real time, make decisions in a timely manner, and improve management efficiency and response speed.

[0072] It can be seen from the above embodiments that the present invention installs a set of intelligent monitoring connection devices of a new design between the front end of the incoming line of the molded case circuit breaker of the charging pile machine and the distribution cable, so that the charging pile can provide charging services to customers at any location in the charging station, thereby solving the problems of charging queues, oil trucks occupying space, low utilization rate of charging facilities, waste of charging resources, etc.

[0073] The present invention can realize fast and safe connection and disconnection of charging piles through the intelligent monitoring cable connection device, thereby improving the flexibility and utilization rate of the charging piles. The intelligent monitoring cable connection device integrates multiple safety protection measures such as electronic locks, connection confirmation power lights, humidity monitoring, temperature monitoring and current monitoring, and can monitor the cable status in real time, and promptly discover and deal with safety hazards.

[0074] The present invention improves the adaptability and stability of the charging pile under different environmental conditions through humidity monitoring and temperature monitoring, and reduces the influence of environmental factors on the performance of the charging pile.

[0075] The present invention reduces maintenance costs: the intelligent monitoring system can upload the working status information of the cable connection device in real time, so that maintenance personnel can quickly locate problems and perform repairs, which significantly reduces maintenance costs and response time.

[0076] The present invention improves user experience: the intelligent monitoring cable connection device provides a more intuitive and convenient operation experience, and the user can intuitively understand the charging connection status through the connection confirmation power light, thereby improving the convenience and satisfaction of use.
