Abstract
This utility model relates to a kind of Emergency Assistance extension set, it is characterized in that, including processing means, processing means receives the input signal of input button, and processing means connects remote host by signaling circuit simultaneously.This utility model is rational in infrastructure, easy to use；Can effectively provide relief alert service, and simple installation, outgoing signal is stable, it is possible to ensure that emergency center can make relief reaction in time.
Description
Technical field:
This utility model relates to a kind of Emergency Assistance extension set.
Background technology:
Relief button in ward is patient when tackling emergency situations, the unique effective means saved oneself, it may be said that be to pass
Important.Therefore to its stability, high efficiency has very strict requirements.The extension set that existing ward is installed, is intended only as commonly exhaling
Crying use, after the call extension of ward, call information is sent to nurse station, and nurse station is provided with main frame, and main frame carries out voice message
And display, nurse does further subsequent treatment again.Its installation is more complicated, and not directly effectively, hardware requirement is high, warp for flow process
Often it is in damaging the state that cannot use.Patient, doctor's use requirement to it cannot be met.
Utility model content:
This utility model main purpose is to provide one can overcome drawbacks described above, it is ensured that dependability and effectiveness
Emergency Assistance extension set.
Emergency Assistance extension set provided by the utility model, is characterized in that, including processing means, processing means receives input
The input signal of button, processing means connects remote host by signaling circuit simultaneously.
Described processing means connects buzzer circuit and display lamp.
Described signaling circuit connects high resistance circuit, and high resistance circuit connects extension set bus further through polarity switching.
Described extension set bus is 2 heart yearns.
Described processing means connects power voltage step down circuit.
The beneficial effects of the utility model are:
Rational in infrastructure, easy to use；Can effectively provide relief alert service, and simple installation, outgoing signal is stable,
Ensure that emergency center can make relief reaction in time.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings and this utility model is described in further detail by embodiment:
Fig. 1 is this utility model frame principle figure；
Detailed description of the invention
As it is shown in figure 1, Emergency Assistance extension set provided by the utility model, it is characterized in that, including processing means, process dress
Putting the input signal receiving input button, processing means connects remote host by signaling circuit simultaneously.
The i.e. CPU of described processing means connects buzzer circuit and display lamp.
Described signaling circuit connects high resistance circuit, and high resistance circuit connects extension set bus further through polarity switching.
Described extension set bus is 2 heart yearns.
Described CPU connects power voltage step down circuit.
Using 2 heart yearns, regardless of positive-negative polarity during installation, all of Emergency Assistance extension set is connected in parallel on this two heart yearn.
The each functions of modules of Emergency Assistance extension set is as follows:
Polarity switching: be responsible for, by uncertain for positive-negative polarity voltage, being converted to the voltage that polarity is fixing, after supply
High impedance circuit.There is polarity switching, so that it may when realizing installing wiring, positive-negative polarity need not be distinguished, given and band is installed
Facilitate.High resistance circuit: its effect is to prevent the elements such as the filter capacitor impact on bus impedance on Emergency Assistance extension set,
As in bus, impedance reduces, extension set signaling can be affected, thus cause main frame to can not receive the phenomenon of extension set signal.Power voltage step down electricity
Road: provide suitable voltage to processing means, it is ensured that processing means is reliably working under assigned voltage.Processing means circuit: become
The control of peripheral function circuit.Buzzer circuit: when inputting button and pressing, send auditory tone cues.Input button: have relief feelings
Pressing during condition, push button signalling sends processing means to and processes further.Display lamp: when button is effective, display lamp is lighted, and represents
The most successfully information is sent out.Signaling circuit: when button is pressed, CPU controls signaling circuit and transmits information to far-end master
Machine.
Above-mentioned case study on implementation is only for understanding this utility model example, and is not to this utility model embodiment party
The restriction of formula.To belonging to obvious change or variation that spirit of the present utility model amplified out still in this utility model
Protection domain in.
