Description
Technical field
The invention belongs to nuclear plant digital computer control system technical field, and in particular to a kind of digital computer
Control system digital quantity input/output test equipment.
Background technology
Digital computer control system is the factory's power station digitlization computer control system of center operation three, is full factory's control
Core, it is a real-time control system, control process variable, execute instruction and alarm, realizes man-machine interaction, final output
Normal or abnormal information.Can it normally the safety of nuclear power station by influence on system operation, to ensure digital computer control system
Safe and stable operation, DCC input and output will be tested during overhaul.
The input-output system of digital computer control system includes 768 digital input amounts (DI) and 384 numerals
Output quantity (DO).According to preventative maintenance rule, each overhaul life will own to two digitlization computer control systems
Input/output checked.The p-wire that originally L-3 producers provide is the soft wiring of a chain, it is necessary to by hand one by one
Insertion, inserted by hand after the drawbacks of be have an other plug slotting do not come off tightly, more grave error is red-black wrong plug
Position or dislocation, need to take a lot of time inspection after having inserted.
The content of the invention
The purpose of this utility model is that developing a kind of digital computer control system digital quantity input/output test sets
Standby, the input for inputting (DI) as digital quantity with the output of digital output (DO) is tested, and test equipment can receive 16 pairs
Test signal.Connection amount is reduced, the actual feelings of joint connection in site have all been fully taken into account in volume, weight, gap, connection
Condition.
What the present invention was realized in：
A kind of digital computer control system digital quantity input/output test equipment, including housing, two calibrating terminals
Row and jointing, each calibrating terminal row have multiple banana joint terminals；Housing is stretched out in banana joint terminal front end, and middle part is fixed on
In housing, rear end is welded on electric wire；It is described to be wired on jointing；The jointing stretches out from the rear end of housing
Outside housing, it is fixedly connected with the casing.
Housing as described above generally hollow cuboid, be divided into above and below two half parts；In housing forward end face along length
Degree direction is evenly equipped with multiple through holes, for fixing banana joint terminal；Center is provided with a through hole in the rear end of housing,
For accommodating jointing.
Jointing as described above is 37 road D-Sub joints, and the banana joint terminal with two calibrating terminal rows leads to respectively
Cross electric wire connection.
As above the communication between calibrating terminal row is realized by connection cable between two jointings.
The beneficial effects of the invention are as follows：
The present invention is using integral chemoprevention people because of design, and plug is once completed, time saving and energy saving.It, which has, reduces connection amount,
The advantage of the actual conditions of joint connection in site has all been fully taken into account in volume, weight, gap, connection.Insert row and on-the-spot terminal
Correspond, a plug in place, saves man-hour.Red and black mark is clear, even if anti-inserted is also not in the consequence of mistake.

Embodiment
The present invention is described further with reference to the accompanying drawings and examples.
As depicted in figs. 1 and 2, a kind of digital computer control system digital quantity input/output test equipment, with DO's
Output is tested as DI input, including housing, two calibrating terminal rows and jointing, and each calibrating terminal row has 16
Individual banana joint terminal.Housing is stretched out in banana joint terminal front end, and middle part is fixed in the housing, and rear end is welded on electric wire.The electricity
Line is connected on jointing.The jointing is stretched out outside housing from the rear end of housing, is fixedly connected with the casing.
The housing generally hollow cuboid, be divided into above and below two half parts.In housing forward end face along its length
Multiple through holes are evenly equipped with, for fixing banana joint terminal.Center is provided with a through hole in the rear end of housing, for holding
Receive jointing.
Described jointing is 37 road D-Sub joints, and the banana joint terminal with two calibrating terminal rows passes through electricity respectively
Line is connected.
As shown in figure 3, realizing the communication between calibrating terminal row by connection cable between two jointings.
The implementation of the present invention is explained in detail above in conjunction with embodiment, but the present invention is not limited to above-mentioned reality
Example is applied, can also be on the premise of present inventive concept not be departed from the knowledge that those of ordinary skill in the art possess
Various changes can be made.The content not being described in detail in description of the invention can use prior art.
