1、 Overview
DCIB series intelligent small bus is a new type of bus, also known as guide rail type air insulated intelligent bus duct, which is an overhead power distribution system. The internal conductor adopts a circuitous U-shaped structure, and the plug-in box can be locked at a fixed position by rotation, and the plug-in box can be plugged in and out at any position of the bus duct without connector. At the same time, the bus system is an intelligent, safe and reliable system, which can monitor the bus in real time.
DCIB Each unit of dcib series intelligent small bus is equipped with sensors, electronic components, etc. when the bus is in operation state, it collects and converts the operation state and electrical parameters of the bus, and transmits them to the intelligent monitoring equipment through the network for real-time inspection and control. There is a program stored in the monitoring module, which can set a reasonable range for all kinds of parameters. If the bus data exceeds the corresponding warning value, it will alarm automatically, so as to ensure the safety of the circuit.

三、插接箱防誤系統(tǒng)The anti misoperation system of the plug-in box includes:>>> ①Anti misoperation warning device;>>> ②Anti misoperation locking device;①nti misoperation warning device: the protective cover of the circuit breaker is used to prompt the alarm. When the plug-in box and the bus are in the charged state, if the plug-in box cannot be reliably connected with the bus, the protective cover of the circuit breaker will always be in the pop-up state. Only when the plug-in box is reliably connected with the bus, the protective cover of the circuit breaker can be in the closed state and can be padlocked. This design is to prevent the plug-in box from closing when it is not connected with the bus or fixed firmly.② Anti misoperation locking device: when the circuit breaker is in the closing position, when the plug-in box is connected or removed from the live bus under abnormal operation procedures, the circuit breaker will automatically trip to prevent plug-in and plug-in box with load. When the equipment leaves the factory, the anti misoperation locking device of plug-in box is put into operation by default. The user can use other electric parameters or non electric parameters to perform associated locking. When the user chooses to cancel the anti misoperation locking on the man-machine interface, the circuit breaker can be remotely operated on the man-machine interface.

5、 Composition of intelligent bus monitoring system
Hardware:
SmartMeter：The module is composed of main control board and CT board, and adopts Modbus RTU master-slave communication protocol. The main control board converts the collected voltage signal, temperature signal, switch signal, secondary current signal collected by CT board into digital signal, which is read and written by HMI after calculation and processing.
Data Supervisory Control Terminal：It is composed of human-machine interface (HMI), serial communication network, Ethernet communication network and wireless communication network. Users can set the corresponding parameters and protection settings for each slave station intelligent module through HMI. Display and compare the electrical parameter data and over limit alarm provided by each module, archive the important data to the historical database, and save the data according to the user's needs.Software:
Intelligent module is based on KEIL development software of MCS-51 series: man machine exchange interface is based on easybuilder Pro development software
6、 Characteristics of intelligent bus monitoring systemTwo remote monitoring solutions are provided for users
1. When the upper computer system is provided by the user: easyaccess2.0 server configured by HMI (data supervisory control terminal), the user can remotely monitor all local devices in real time through Internet.
2. When the upper computer system is supported by the equipment manufacturer: SCADA monitoring software is configured with web publishing function, users can remotely monitor all local equipment in real time through Internet Explorer.
7、 Intelligent data monitoring and Analysis ReportData acquisition: upload all the data of each starting box and plug-in box to HMI through the configuration of the product, convert and calculate the collected data, and provide users with common real-time data display window, alarm parameter setting and display window, user permission setting and login window.Data analysis: by EB Pro configuration uploads all data of each starting box and plug-in box to HMI, converts and calculates the collected data, and provides users with common real-time data display window, detailed real-time data menu query window, power and temperature historical data query window, system parameter setting window, alarm parameter setting and display window, user permission setting and login window.Data report: each device can detect 4-point temperature; it can obtain electric energy and temperature files as low as per second; it can closely track the electric energy consumption and temperature curve in a short time; user-defined data rolling days; it can export the recorded historical data through XML, CSV and TXT.
