Embodiment Construction

[0019] As attached figure 1 As shown, the network-type power black box includes: a communication module 1, a microcontroller module 2, a display module 3, a power supply module 4, and a configuration program 5.

[0020] The communication module 1 includes an RS-485 interface 6, a debugging serial port 7, an Ethernet interface 8 and a wireless transmission module interface 9. Among them, the total number of RS-485 interface 6 is 4, and the circuit schematic diagram of a single RS-485 interface 6 is as follows figure 2 As shown, the circuit uses the SN75LBC184 chip to convert the microcontroller's own asynchronous serial bus into a 485 bus. This chip has the characteristics of anti-lightning and strong anti-interference ability. At the same time, the 6N137 high-speed optocoupler is used to realize the microcontroller and The isolation between SN75LBC184, through the control of the DE end of the SN75LBC184 chip, realizes the control of the hardware data flow direction of each interf...

The electric black box connects various data collection terminals by RS-485 and RS-232 ports in a hanging mode, realizes the communication with an upper position management unit by Ethernet, CDMA / GPRS / GSM and the like, has abundant data transmission modes, flexible configuration and good automatic management and can individually run free from the upper position machine.

Description

Technical field [0001] The invention relates to a network type power black box suitable for a power distribution automation system, and belongs to the technical field of data acquisition. Background technique [0002] With the gradual deepening of reform and opening up and the gradual marketization of electricity, the contradiction between power supply and demand gradually tends to balance. Under this background, user demand has changed from "power use" to "high-quality, high-reliability power energy use. ", and then put forward the demand for power supply quality and power supply reliability requirements. Distribution network automation has emerged as an important technical means to achieve the above goals. [0003] The distribution automation system (Distribution Automation System, abbreviated as DAS) is an automation system that enables power distribution companies to monitor, coordinate, and operate power distribution equipment in a real-time manner from a distance. Its conte...
