Description
Technical field
The utility model relates to a kind of single input control loops for realizing dual signal acquisition, belong to switchgear control technology neck
Domain.
Background technique
Intelligent control device plays a part of intellectual monitoring in switchgear, protection, far controls, in breaker of switch cabinet
There is very important status during the monitoring and protecting of the running environment of monitoring for protection and cabinet body.
Temperature controller, in addition to exporting various monitoring temperature signals, can also export when abnormal during carrying out monitoring temperature
A variety of alarm signals, such as deficient temperature, excess temperature or unexpected abnormal temperature information can all generate alarm, and switchgear is come
It says, in the acquisition and processing to signal, the exercising result of sometimes different signals may be identical.Such as Intelligent control
For device after collecting the either unexpected abnormal temperature information of excess temperature, carrying out respective treated the result of the action all is so that open circuit
Device tripping, to guarantee safety.
But Intelligent control device needs during the corresponding alarm signal of acquisition is handled and makes corresponding actions
Different signal sampling channels is set for different alarm signals, while the CPU in control device needs to carry out different alarms
The processing of signal.And the control instruction that some alarm signals export after being handled is identical, such as is all control breaker
Tripping.So, the manufacture volume that extra Information Collecting & Processing channel not only results in Intelligent control device increases, cost increases
Add, while the processing speed decline of the CPU of Intelligent control can also be made to cause certain delay, reduces security of system.
Utility model content
The purpose of this utility model is to provide a kind of single input control loops for realizing dual signal acquisition, solve existing
Identical control instruction is exported after being handled in technology due to a variety of alarm signals, and causes to occur at extra information collection
Manage channel, cause the manufacture volume of Intelligent control device to increase, increased costs the problem of, and make the place of the CPU of Intelligent control
Speed decline is managed, the problem of causing certain delay, reduce so as to cause security of system.
To achieve the above object, the technical solution of the utility model is: a kind of single input control for realizing dual signal acquisition
Circuit, i.e. control loop scheme one, including power supply line and the first circuit being arranged in parallel between power supply line positive and negative anodes and second
Circuit, coil and the first alarm actuating contact WJ1 of first time routing relay K1 are composed in series, and the second servo loop is by second
Alarm actuating contact WJ2 is composed in series with signal acquisition point ln, the normally opened contact of the relay K1 and the second alarm actuating contact WJ2
It is in parallel.
Control loop scheme two: on the basis of control loop scheme one, the first alarm actuating contact WJ1 is temperature controller the
One alarm actuating contact, for exporting overtemperature alarm signal；The second alarm actuating contact WJ2 is the second alarm actuating contact of temperature controller, is used for
Output temperature abnormal alarm signal.
Control loop scheme three: on the basis of control loop scheme one, the coil of the relay K1 also with one two
Pole pipe D reverse parallel connection.
The utility model by the alarm actuating contact of relay and temperature controller formed the acquisition to the two-way warning message of temperature controller,
And it is input to the control loop in the input channel all the way of Intelligent control device.The model of the output warning message of temperature controller can be expanded
It encloses, and can consider processing and the result of the action of the Intelligent control device to multi information in conjunction with practical, so as to save intelligent behaviour
The processing module space of control improves it and handles the speed of service.Circuit is simple, reasonable, and easy to operate, safety can be saved and is fabricated to
This.
Detailed description of the invention
Fig. 1 is the structure principle chart of control loop described in the utility model.
Specific embodiment
The embodiments of the present invention is described further with reference to the accompanying drawing.
The utility model proposes a kind of single input control loops for realizing dual signal acquisition, including power supply line and parallel connection to set
Set the first circuit and the second servo loop between power supply line positive and negative anodes, the coil and first of first time routing relay K1
Alarm actuating contact WJ1 is composed in series, and the second servo loop is composed in series by the second alarm actuating contact WJ2 and signal acquisition point ln, described
The normally opened contact of relay K1 is in parallel with the second alarm actuating contact WJ2.
The coil of relay K1 in first circuit also with a diode D reverse parallel connection.
The utility model is applied to the specific embodiment of switchgear monitoring for protection, as shown in Figure 1,1n is intelligent protection observing and controlling
The signal acquisition point of device, K1 are relay, including its coil and its normally opened contact, and WJ1, WJ2 are that the alarm of temperature controller is touched
Point exports on-off model.The normally opened contact of relay K1 and WJ2 are connected in parallel to 1n --- the letter of Intelligent protection measuring controller
On number acquisition channel, WJ1 connects with the coil of relay.Temperature controller will export overtemperature alarm information when the temperature is excessively high,
The contact closure of WJ1, K1 enter information into Intelligent protection measuring controller；When temperature is not simple raising but occur
When abnormal, the alarm actuating contact WJ2 of temperature controller is closed and directly the signal is input in Intelligent protection measuring controller.Through intelligence
Trip operation is exported after the processing of protection supervisory equipment.Multi signal is able to achieve in this way to be input on single pass circuit.
As further improvement of these options, D is diode, reversely simultaneously by the coil of diode D and relay K1
Connection, plays the role of afterflow, and the counter electromotive force generated when coil losing electricity is avoided to generate loss to element.
By above-mentioned the technical solution of the utility model, the control that the contact composition of relay and temperature controller is only used only is returned
Line structure realizes the simplification of Information Collecting & Processing modular structure in Intelligent control device, not only saves system configuration cost,
The pressure that CPU is handled in smart machine is alleviated simultaneously.
The utility model is described above in conjunction with attached drawing, but the utility model be not limited to it is above-mentioned specific
Embodiment can also make various transformation when not departing from the utility model aims and scope of the claimed protection
And equivalent substitute, these are belonged within the protection scope of the utility model.
