Highly flexible relay array system

Abstract

The invention discloses a highly flexible relay array system, and belongs to the field of relays. The system comprises a main controller, an RS485 bus and a driving circuit; the main controller receives a command sent by an upper computer through the interface circuit and executes corresponding operation through the driving circuit; the RS485 bus realizes communication through the interface circuit; the driving circuit is used for driving the relay array; and the relay array realizes an array system through a specific logic structure. According to the invention, a specific logic structure is adopted, the topology of the relay array is innovatively designed, and a highly flexible and configurable relay architecture is realized, so that the relay architecture can meet the complex requirements on the relay array in scientific research and production tasks. According to the array system realized by the invention, the defect that only relay customization can be realized in a conventional scheme can be simplified, relay board card multiplexing is realized, the development period is shortened, and the cost of a test system is reduced.

Description

technical field [0001] The invention relates to the technical field of relays, in particular to a highly flexible relay array system. Background technique [0002] The relay array system can realize channel switching and function multiplexing, and it is widely used in the test and measurement work of R&D and production. In the process of R&D and production, it is often necessary to test a large number of signals. Due to the high cost of a single test equipment such as a multimeter and oscilloscope, and only a single signal or very few signals can be measured at the same time, it cannot meet the multi-point test function. By adopting time-division multiplexing mode and relay switching, multiple groups of signals are sequentially switched and strobed to the test equipment, so that a single device can measure multiple groups of signals. [0003] Based on the huge demand of the test system for the relay array, test manufacturers have developed a variety of relay boards. For ex...

Problems solved by technology

The number of test signals in many test systems is uncertain, and flexible expansion functions are required. The fixed-function relay arrays on the market cannot meet this demand. Only relevant boards can be selected according to specific needs, which cannot be flexibly applied.
