In recent years, with the rapid development of power grid, the demand for power supply reliability is getting higher and higher.In order to improve the reliability of power supply, it is necessary to overhaul and transform the existing distribution network.Power grid transformation is a huge project, with a considerable amount of work and a very long construction period.Inevitably, there will be power outages on power grid lines.How to transform the power grid without affecting the reliability of power supply is the key to the management and control of power supply reliability.PUSR actively cooperates with the customer's research and development of the distribution network AC wireless monitoring system based on IoT Router.Real-time monitoring of AC working status of distribution network helps customers improve the efficiency of distribution network maintenance and transformation.
The monitoring project of a city's distribution network monitors the operation status of two AC circuits. When AC 1 or AC 2,Two kinds of fault information signals are sent respectively when one of the circuits is powered down or the two circuits are powered down at the same time.One is the real information, which reflects the current operation status of the two channels of AC, which channel is currently supplying power,The real information can be sent to the mobile phone of the maintenance personnel on duty;One is a dummy message: a dummy long powered status message is sent at all times,The virtual information is uploaded to the communication station of the provincial Bureau through the background communication.
An uninterruptible power supply is led from the cabinet to supply power to the AC monitoring module and the IoT Router through the control switch.The alternating-current monitor module acquires voltage of two paths of alternating-current inputs,The AC acquisition status is communicated with the IoT Router device via the 485 modbus protocol.The IoT Router device identifies the communication state information after collecting the communication state information,Send two different signals: one is sent to the mobile phone of the designated operation and maintenance personnel by SMS when any failure occurs in the AC input.The other path is that the IoT Router device is connected with the background and sends a virtual message with normal long-term communication status.
Best IoT Router plays a key role in distribution room monitoring applications. It provides the following features and benefits:
IoT Router can remotely monitor various parameters of the power distribution room, such as voltage, current, power, temperature, etc.By connecting to the 4G network, users can access data through the network anytime and anywhere.Monitor the status of power equipment and take control measures in time.
IoT Router has high-speed and stable data transmission capability, which can realize real-time transmission of monitoring data in the power distribution room.This can help users quickly obtain the current power status, detect abnormal conditions in time, and take appropriate measures.Avoid power outages or other unexpected situations.
Through IoT Router, users can remotely manage and control the equipment in the power distribution room.Device configuration, parameter setting and remote operation, such as remote on-off control and device restart, can be performed through remote access.This reduces manual intervention, improves operational efficiency, and reduces potential risks in field operations.
IoT Router usually has strong network security functions.It can protect the monitoring system of the distribution room from network attacks and malicious intrusions.It can support security mechanisms such as VPN encrypted communication, firewall settings and access control.Ensure the confidentiality, integrity and reliability of data.
IoT Router can realize remote monitoring, data transmission, remote management and control in the monitoring application of distribution room.And provide network security protection.It provides convenience and reliability for the operation and maintenance of the distribution room, and improves the efficiency and reliability of the distribution system.
