In figure: 1, PLC; 2, transmitter; 3, touch display screen; 4, buzzer siren; 5, magnetic valve; 6, rly. group; 7, frequency transformer; 8, blower fan; 9, ups power.
Embodiment
Below in conjunction with accompanying drawing, the dress of this fluted body armature in the utility model being hung tool, its concrete structure, feature are described in detail as follows:
As shown in Figure 1, a kind of oxygen uptake safeguards system, this system realizes based on PLC. Specifically, this system comprises PLC 1, touch display screen 3, blower fan 8, ups power 9, rly. group 6, magnetic valve 5, transmitter 2, frequency transformer 7, sound damper and strainer etc. As shown in Figure 1, PLC 1 is connected with transmitter 2, touch display screen 3, buzzer siren 4, rly. group 6, frequency transformer 7 respectively, its repeat circuit group is connected with frequency transformer 7 with PLC 1, magnetic valve 5, and frequency transformer 7 is connected with rly. group 6, PLC 1, blower fan 8 and ups power. Sensor also it is provided with in the inside of enclosed space.
PLC 1 is connected with touch display screen 3, can set the monitoring range of gas standard, the running frequency of blower fan by PLC 1, it is possible to check parameter historic records, gas concentration numerical value and buzzing alarm display from touch display screen 3.
Described rly. group 6 is connected with PLC 1, magnetic valve 5, frequency transformer 7, and when PLC 1 sends signal to rly. group 6, rly. group 6 sends signal to frequency transformer 7 and magnetic valve 5, carries out frequency transformer 7 and opens, stops and the action of magnetic valve 5 folding.
Enclosed space environment residing for personnel, by sending signal to buzzer siren 4, is badly reported to the police by PLC 1.
The simulating signal that PLC 1 transmits by analyzing transmitter 2, analyzes the situation of enclosed space environment residing for personnel. Further, the signal of sensor is converted to the signal that can be identified by described PLC by described transmitter. System transmitter used comprises oxygen transmitter, carbonic acid gas transmitter and pressure unit. Specifically, sensor comprises and draws together oxygen concentration sensor, gas concentration lwevel sensor and pressure transmitter.
After the analog signals that pressure unit transmits is analyzed by PLC 1, by running blower fan so that the air content of enclosed space reaches the numerical value of Plain environment. Due to crowd's respiration of enclosed space, consume oxygen produce carbonic acid gas, when enclosed space oxygen be depleted to do not meet normal service requirements time, after the analog signals that oxygen transmitter transmits is analyzed by PLC, Controlling solenoid valve is opened, and takes a breath. With reason, when carbon dioxide content exceeds standard, magnetic valve is opened, and carries out enclosed space ventilation.
Selecting the oxygen content carried out when enclosed space is taken a breath is 12%, and carbon dioxide content is 1%. When running blower fan 8, enclosed space pressure value is 70KPa, enclosed space pressure value during blower fan 8 auto stop, is the greatest measure that blower fan can pressurize. Preferably, in this system, blower fan is Special high-voltage blower fan, and its pressurization maximum reaches 30Kpa, therefore the pressure maximum that enclosed space can reach may not exceed the air pressure+30Kpa in system location. When each gas standard that PLC 1 analyzes enclosed space do not meet require time (oxygen<and 12%, carbonic acid gas>1%, pressure<70Kpa), while performing blower fan start and stop, magnetic valve opening and closing movement, control hummer runs, and reports to the police.
Preferably, frequency transformer is the frequency transformer that two-phase turns three-phase, after two-phase power supply is converted to three-phase supply, for fan. Meanwhile, the frequency conversion effect of frequency transformer, increases the stability of whole system. In addition, owing to being personnel's safeguards systems, therefore refer to ups power to provide whole system electricity consumption, ensure in the event of a power failure, personnel's safeguards system still reliability service.
Finally it is noted that the foregoing is only preferred embodiment of the present utility model, it is not limited to the utility model, although the utility model being described in detail with reference to previous embodiment, for a person skilled in the art, technical scheme described in foregoing embodiments still can be modified by it, or wherein part technology feature carries out equivalent replacement. All within spirit of the present utility model and principle, any amendment of doing, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
