Description
The utility model belongs to a kind of interface arrangement with microcomputer control forceful electric power break-make.
With system controlled by computer forceful electric power break-make, usually the Line Card that needs microcomputer of design and forceful electric power at present, the wiring board of this wiring board and microcomputer is installed in the same cabinet, and the on off operating mode indicating device with loop-coupled connection terminal of forceful electric power and switch will be set outside the cabinet.The shortcoming of above-mentioned technology is: 1. strong because of multichannel---light current interface circuit and microcomputer are installed in the same cabinet, during the forceful electric power break-make microcomputer are disturbed, and the microcomputer reliability is reduced, even cisco unity malfunction.Overcome interference, just need take the distance between shielding measure or increase computer line plate and forceful electric power circuit, consequently cost increases, and the cabinet volume increases, and is unfavorable for miniaturization.2. if buy the interface board of selling on the market, then need consider installation dimension, reach problems such as anti-interference, this increases design complexity, and product development cycle is long, and the user is the design interface plate voluntarily, then more bothers the construction cycle lengthening.3. interface board is installed in the cabinet, and connection terminal and on off state display need be installed in outside the cabinet.Therefore, need between interface board and forceful electric power connection terminal and the display be connected with lead, tie point is many, and poor reliability is installed complexity, the cost height.
The purpose of this utility model is to overcome shortcoming in the above-mentioned technology, provide a kind of driver, buffer circuit, the demonstration of forceful electric power on off state and lead-out terminal are contained in the housing to separate with microcomputer circuit, the forceful electric power switch is directly drawn by lead-out terminal, do not disturb microcomputer circuit, a kind of interface arrangement easy to use.
The utility model solves by following scheme:
The display that driver, isolating device, forceful electric power switch is reached the forceful electric power switch on and off state that external enwergy is shown is contained in the housing, and separate with microcomputerized controller, the driver signal input end is directly drawn so that be connected with microcomputerized controller by the connector that is contained on the housing, and forceful electric power switch loop is directly drawn by the lead-out terminal that is contained on the housing.
The utility model has the advantages that:
1. because strong power part and lead-out terminal are made of one, need not be installed in the housing, housing itself can be used as the shielding of microcomputer, greatly reduces strong power part microcomputer is disturbed, and improves the reliability of microcomputer.
2. easy to use, flexible for installation, the utility model is one group with eight switching value unit, have on its housing and be suitable for and any eight connectors that machine is connected, incoming level and Transistor-Transistor Logic level compatibility are joined the utility model and microcomputer I/D mouth with a flat cable, i.e. the may command forceful electric power.The utility model can be installed in the outer position arbitrarily of housing as required.Utilize the utility model can shorten product development cycle, quicken the electromechanical integration process.
3. reduce cost.The utility model makes the designer avoid considering that strong power part is installed on a series of problems of bringing in the microcomputer case, and the cabinet size can be dwindled, and the forceful electric power switching device directly is connected with lead-out terminal, and freedom from wires is saved human and material resources, improves reliability.
