Abstract
The utility model discloses a kind of body intelligent terminal body signal input circuit, and it includes the body signal in parallel with body trip(ping) circuit, it is characterised in that：Body signal separates with body trip(ping) circuit；And body signal is connected with control relay XJ normally opened contact；The positive input terminal of control relay XJ coils is connected with body trip(ping) circuit, and the negative input end of control relay XJ coils is connected with operation power negative terminal；The output end of normally opened contact and the input of signal input module connect；Solve the problems, such as remote signalling power supply and operation power conflict, prevent body signal circuit short circuit from causing operation power to be spaced apart tripping operation, so as to cause protection not trip；Meet the remote signalling test of body signal, effectively prevent signal testing from causing main body protection outlet tripping operation.
Description
Technical field
It the utility model is related to body intelligent terminal control technology, more particularly to a kind of body intelligent terminal body signal is defeated
Entry loop.
Background technology
The signal such as JFZ-600R type body intelligent terminals, the body grave gas of body signal circuit, pressure regulation grave gas and this
Body trip(ping) circuit and together, when body signal needs maintenance test, attendant is exactly to be opened in remote signalling using conventional method
When entering on terminal artificial " just establishing by cable into ", now equivalent to body trip(ping) circuit has been connected, cause main body protection outlet tripping operation, draw
Send out power outage unplanned；In addition, the dc source that access remote signalling is opened into plate body signal derive from operation power, with signal time
The remote signalling power supply on road has conflict, once the remote signalling loop of access body signal has short circuit, operation power is spaced apart tripping operation, so as to
The technical problem such as cause protection not trip.
Utility model content：
The technical problems to be solved in the utility model is：A kind of body intelligent terminal body signal input circuit is provided, with
Solves the letter such as body grave gas, pressure regulation grave gas of the body signal circuit of the JFZ-600R type body intelligent terminals of prior art
Number with body trip(ping) circuit and together with trigger unplanned power outage；The dc source into plate body signal is driven in access remote signalling
Operation power is come from, has with the remote signalling power supply of signal circuit and conflicts, once the remote signalling loop of access body signal has short circuit, is made
Operation power is spaced apart tripping operation, so as to the technical problem such as cause protection not trip.
The technical solution of the utility model：
A kind of body intelligent terminal body signal input circuit, it includes the body signal in parallel with body trip(ping) circuit,
Body signal separates with body trip(ping) circuit；And body signal is connected with control relay XJ normally opened contact；Control relay
The positive input terminal of XJ coils is connected with body trip(ping) circuit, and negative input end and the operation power negative terminal of control relay XJ coils connect
Connect；The output end of normally opened contact and the input of signal input module connect.
The output end of normally opened contact is connected with photoisolator input, photoisolator output end and signal input module
Input connection.
The beneficial effects of the utility model：
JFZ-600R type body intelligent terminal body signal circuits are improved by the utility model, are tripped back being attempted by
The body signal wire on road is transferred on relay, and the normally opened contact of the relay is introduced into body signal remote signalling opens into using remote signalling
Power supply, thoroughly body signal circuit is separated with trip protection loop, when carrying out body signal " just establishing by cable into " test, due to
Access remote signalling open into be relay normally opened contact, the positive electricity will not connect trip protection loop, can solve remote signalling power supply
The problem of conflicting with operation power, meet the remote signalling test of body signal, and can effectively prevents signal testing from causing body to be protected
Shield outlet tripping operation；The utility model solves the problems, such as remote signalling power supply and operation power conflict, prevents that body signal circuit is short-circuit
Operation power is caused to be spaced apart tripping operation, so as to cause protection not trip；Meet the remote signalling test of body signal, effectively prevent letter
Number test cause main body protection outlet tripping operation.
Brief description of the drawings：
Fig. 1 the utility model structure diagrams.
Embodiment
A kind of body intelligent terminal body signal input circuit, it includes the body signal in parallel with body trip(ping) circuit,
Body signal separates with body trip(ping) circuit；And body signal is connected with control relay XJ normally opened contact；Control relay
The positive input terminal of XJ coils is connected with body trip(ping) circuit；Operation power is introduced into, the negative input of control relay XJ coils
End is connected with operation power negative terminal；Body signal remote signalling input is connected with control relay XJ normally opened contact, using remote signalling
Power supply；The output end of normally opened contact and the input of signal input module connect.
The output end of normally opened contact is connected with photoisolator input, photoisolator output end and signal input module
Input connection.
The effect of photoisolator is that the interference signal in input signal is isolated, to protect input module.
Normally opened contact of the present utility model is connected with the positive and negative of remote signalling power supply, thus reached body signal power source and
The effect of trip(ping) circuit operation power isolation.
