Abstract
The invention relates to a device applied in medical air supply engineering to monitor pipeline pressure, in particular to a digital-display-type pressure alarming box which comprises an alarming box. The digital-display-type pressure alarming box is characterized by further comprising a pressure transmitter which is mounted in a gas pipeline, an ARM single chip microcomputer is mounted in the alarming box body, and the pressure transmitter is connected with the ARM single chip microcomputer. The digital-display-type pressure alarming box has the advantages that the ARM single chip microcomputer is adopted as a control unit, so that the digital-display-type pressure alarming box is high in control accuracy and stable in performance; due to using of the pressure transmitter, a pressure range can be preset, and pressure in an air pipe can be monitored in real time; an acoustic-optical-electric alarm can give an alarm when incorrect circumstances appear.
Description
Technical field
The present invention relates to a kind of device that is applied to monitor in medical gas supply engineering line pressure, specifically a kind of digital display type pressure alarm case.
Background technology
Medical gas feed system is an important and requisite ingredient of modern hospital, and it comprises medical oxygen system, vacuum suction system, compressed air system, laughing gas, nitrogen system and carbon dioxide system and central station etc.By the reasonable construction of medical gas central tube systems engineering, make hospital obtain a powerful air supply system with lower investment, guarantee that the medical system of hospital is efficiently moved.Medical gas concentrated supply system Construction is crucial, guarantees to use work on the spot pressure, can not superelevation can not owe low, guarantees enough flows, and safe and continuous is top priority.Medical gas warning system is as the supporting project of medical gas construction project, by the scattered of past with to the setting of levying property, be transitioned into unified mark Huaihe River and must configure.But the alarm monitoring system in past, mainly, with scattered settings such as monitoring form case, LED Units, need manually monitor, and function singleness, the weakness such as can not manage concentratedly, no matter be in structure, or imperfection all in function.
Summary of the invention
The invention provides that a kind of pressure shows in real time, the digital display type pressure alarm case of overpressure alarm.
The concrete technical scheme adopting of the present invention is:
Digital display type pressure alarm case, comprise warning box, it is characterized in that, also comprise pressure unit, pressure unit is arranged in gas piping, ARM single-chip microcomputer is installed in warning box, pressure unit is connected with ARM single-chip microcomputer, pressure unit detects gaseous tension, pressure signal is converted to the electric signal of 4-20mA, pass to ARM single-chip microcomputer, ARM single-chip microcomputer is according to pre-set programs judgement gaseous tension ruuning situation, if any extremely sending alerting signal output, and show in real time gaseous tension numerical value and gas running status by LCDs.Pressure unit has MPa, Bar, KPa etc., can need to adjust voluntarily according to user.
Wherein, LCDs, acousto-optic-electric alarm are installed on described control box shell, are reported to the police and eliminate button, LCDs, acousto-optic-electric alarm, the elimination button of reporting to the police are connected with ARM single-chip microcomputer.
Wherein, described pressure unit volume pressure detection scope is :-0.1～1.5MPa, and the overpressure alarm range of adjustment of general positive compression air is: 0.2 to 1MPa; The range of adjustment of negative compression air overpressure alarm is :-0.8 to 0.2MPa; The range of adjustment of oxygen overpressure alarm is: 0.03 to 0.85MPa.
Wherein, the RS-485 or the CAN bus interface that are connected with ARM single-chip microcomputer are also installed, to facilitate later expansion and communication on described warning box.
Compared with prior art, advantage of the present invention is:
1) adopting ARM single-chip microcomputer as control module, to have advantages of that control accuracy is high, stable performance, 2) use of pressure unit can preset pressure limit, and endotracheal pressure is monitored in real time; 3) acousto-optic-electric alarm can be reported to the police to error situation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Embodiment
As shown in Figure 1, digital display type pressure alarm case, comprises warning box, also comprises that pressure unit, pressure unit are arranged in gas piping, and ARM single-chip microcomputer is installed in warning box, and pressure unit is connected with ARM single-chip microcomputer; LCDs, acousto-optic-electric alarm are installed on described control box shell, are reported to the police and eliminate button, LCDs, acousto-optic-electric alarm, the elimination button of reporting to the police are connected with ARM single-chip microcomputer; The CAN bus interface being connected with ARM single-chip microcomputer is also installed on described warning box.
Described pressure unit volume pressure detection scope is :-0.1～1.5MPa, and the overpressure alarm range of adjustment of the positive compression air that can as required pressure unit be detected is: 0.2 to 1MPa; The range of adjustment of the negative compression air overpressure alarm that pressure unit detects is :-0.8 to 0.2MPa; The range of adjustment of the oxygen overpressure alarm that pressure unit detects is: 0.03 to 0.85MPa, to realize the object of accurate monitoring.
Pressure transducer is arranged in gas piping, and pressure signal is converted into current signal and passes to control module.Control module receives the 4-20ma current signal that pressure unit transmits, and converts it into continuous digital signal.According to default restriction up and down, judge whether superpressure or under-voltage of gaseous tension, if pressure over range, warning box sends acousto-optic-electric and reports to the police, and reminds patrol officer to make a response to medical center air supply system, avoids security incident generation.Display unit shows gas pressure value and pressure state in real time.
