Problems solved by technology

Its disadvantage is that the switch array can only open one channel at a time, but cannot selectively open multiple channels, which greatly limits the application
If a self-locking relay array controller is used, although multiple channels can be opened, it is expensive, and its array size cannot be compared with the existing multiplexers on the market

Embodiment Construction

[0038] In the circuit design, the output part of the multi-channel switch is usually similar. For the convenience of illustration, sometimes only the specific structure of a channel branch is drawn. For those in the industry, it is easy to extend the connection method of the first channel to Switch output for other channel branches. The scale of the same switch array can be from two-way to multi-way, and the number of channels drawn in the diagram can not be regarded as the limit range of the content of the invention, and people in the industry can implement the multi-way switch array without creative labor according to its implementation mode. way to control.

[0039] Embodiment 1 of the present invention is as Figure 4 As shown, the present invention provides a control device capable of simultaneously opening multiple switch channels, including a multiplexer 300 , an electric energy storage unit group 310 and a switch unit group 320 . The multiplexer 300 includes a group ...

Abstract

The invention discloses a control device for controlling a switch array. A mature large-scale multi-division multiplexer on the market is used as a basic module, and a large-scale switch array controlcircuit is conveniently realized. The device comprises a one-to-many multi-division multiplexer, an electric energy storage unit group and a switch unit group, each output port of the multi-divisionmultiplexer is respectively connected with control ports of the electric energy storage unit and the switch unit, the multi-way switch units are controlled to be turned on / off, the on / off states of the switch units are kept, the on / off states of the switch units are independent of one another, and the automatic turn-off function of the switch units is achieved through the discharge characteristicof the energy accumulator.

Description

technical field [0001] The present invention relates to electronic circuits, and in particular to a control device for controlling a switch array. Background technique [0002] There are many applications in electronic circuit devices that need to control the on / off of channels, and these switches can drive high power or high voltage signal / energy switches, such as relays. Arrays are often used in practical applications to selectively control the on / off of array units to achieve specific application purposes. The signals or currents required by the control signals of these switches are generally small, and multi-division multiplexing chips can be used to complete the control purpose of array switches. For example, Analog device company provides a complete series of multiplexers, and a typical example is ADG732 can control up to 32 switches, and through 5 address selection signals, it can flexibly realize the opening / closing of multi-channel switches. With the solid state re...
