The invention provides a control acquisition device applied to distribution line fault indicator detection. The control acquisition device comprises an input state detection module, a wireless signal receiving module, an FPGA and an optical fiber communication module. The input state detection module detects an input signal to acquire a corresponding contact state signal. The wireless signal receiving module receives a fault indicator wireless signal and parses the received wireless signal to acquire fault indicator action and reset state information. The FPGA acquires the contact state signal and wireless communication information, and sends the contact state signal and the wireless communication information to an output control device through the optical fiber communication module. According to the invention, the fault indicator action state is acquired in real time; the time error is less than 100 microseconds; output signals outputted by the fault indicator such as idle contact signals, level contact signals, wireless signals and the like are acquired; the requirements of site tests and type tests are met; and the output of the device uses optical fiber output and has good safety.
Description
technical field [0001] The invention relates to a collection device, in particular to a control collection device for detecting fault indicators of power distribution lines. Background technique [0002] Although a large number of line fault indicators are used in power distribution lines, and there are a large number of manufacturers, there is no unified indicator standard and technical specification at home and abroad. They are not the same, and the technical level of the products is very different. When the line fails, the correct rate of the indicator action is low, and it is prone to false alarms and false alarms. [0003] In 2010, the State Grid Corporation promulgated the enterprise standard "Q / GDW436-2010 Technical Specifications for Distribution Line Fault Indicators", which uniformly stipulated the functions, performance indicators and test methods of fault indicators, and stipulated a variety of functions and performance test items. Although the advanced fault i...
