Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of insulation detection of charging piles, and in particular to an insulation detection device for an energy storage DC charging pile. Background Art
[0002] With the large-scale construction and application of electric vehicle charging stations and charging piles, their safety has received more and more attention. In particular, DC charging piles have high power, large volume, high voltage, and are often equipped with batteries for energy storage, with complex structures. When the insulation on the DC side of the charging pile output is not good, it will cause equipment damage, fire, and electric shock. Since the leakage fault on the DC output side cannot activate the leakage protector on the AC side, it is particularly important to increase the insulation detection on the DC side. Summary of the invention
[0003] The invention provides an insulation detection device for an energy storage DC charging pile, which has a high intelligence level and high detection accuracy.
[0004] The technical solution adopted by the present invention to solve its technical problems is: an insulation detection device for a DC energy storage charging pile, comprising a cloud server, an online monitoring system for leakage detection of a charging pile and a client; the cloud server is connected to the client via HTTP, and the cloud server is connected to the online monitoring system for leakage detection of a charging pile via TCP; the online monitoring system for leakage detection of a charging pile comprises a charging pile leakage detection sensor, a communication control module based on NB-IoT, a coordinator node, and an embedded gateway.
[0005] The charging pile leakage detection sensor is equipped with an infrared sensing sensor. The NB-IoT wireless communication technology is used between the charging pile leakage detection sensors. The charging pile leakage detection sensor is regarded as a network available coordinator node in the network. With the help of this node, network alarm node information is collected in real time. At the same time, the information is shared to the gateway and then transmitted to the remote service background.
[0006] The cloud server is built in a multi-user access mode. When a client logs in to the system, it is necessary to confirm its identity. If the username and password are verified correctly, it is allowed to enter the system, and certain login permissions are required. When logging in with the mobile app, corresponding settings are also made. If the username and password are verified correctly, it is allowed to enter the system, and corresponding permissions are required.
[0007] After the charging pile leakage detection sensor detects leakage, the sensor installed on the charging pile leakage detection device senses the leakage current and triggers an alarm. This alarm information will be transmitted to the embedded gateway terminal by the NB-IoT network. The gateway has intelligent functions. After processing the data, it will display the location information of the alarm device. The location information will also be sent through NB-IoT to the specific IP preset by the platform. The relevant users can use the server to query whether the device is leaking.
[0008] The beneficial effects of the present invention are as follows: the insulation detection device for the energy storage DC charging pile is monitored through the NB-IoT wireless communication technology, each alarm is used as an NB-IoT network node, and the WSN networking method is combined into a real-time connected wireless network. The data is transmitted to the DATA network, which contains the alarm information of all field nodes. In this transmission process, when the data information sharing between the coordinator and the embedded gateway is completed, the alarm node information is first gathered to the gateway, and the background user query and setting commands are sent to the system network for information verification. The role of the embedded gateway in real-time alarm and data upload also highlights the important level. The abnormal information generated by the charging pile leakage detection device is first monitored by the NB-IoT module and transmitted through the module circuit motherboard in the system with the help of a fixed IP. After the data is transmitted to the server, the data is reviewed and judged according to the alarm threshold pre-set by the server to complete the outbound and push of the alarm information.
[0009] The device can query alarm information through the mobile client, and ensure that the alarm situation can immediately notify relevant maintenance processing and remediation based on the information. BRIEF DESCRIPTION OF THE DRAWINGS
