Embodiment
Below in conjunction with accompanying drawing the utility model steel cylinder gas circuit switched system is described in further detail.
As shown in Figure 1, the utility model steel cylinder gas circuit switched system comprises: a plurality of steel cylinders 1, steel cylinder 1 is connected with COMM communication 4 by tracheae 3, also is provided with reduction valve 2 on the connecting end of steel cylinder 1 and tracheae 3.And gas equipment 5, gas equipment 5 is connected with COMM communication 4.
As shown in Figure 2, COMM communication comprises pressure transducer 6, solenoid valve 7 and the controller 8 to be connected with pressure transducer 6, solenoid valve 7 respectively, and pressure transducer 6 and solenoid valve 7 are connected with steel cylinder.COMM communication further comprises an alarm module (not shown).
As shown in Figure 3, during work, whether controller can detection system be Default Value, and when confirming as Default Value, system enters automatic source of the gas to be switched, acquiescence be the outside air feed of A source of the gas, carry out corresponding actions according to current system model then; When confirming as non-Default Value, will read data again, comprise system model and source of the gas number, carry out corresponding actions according to current system model then.In the course of the work, system can detect any one button of whether pressing among A, B, C, the D, under the situation that does not have button, system will determine whether taking action according to the length of time of standby, if system will carry out corresponding actions according to current system model greater than 6 seconds the time of standby; If the deficiency of time of standby 6 seconds will not taked any action.Under the situation that detects the actuation of keys generation, tutorial light shows: red light Chang Liang, all the other lamps extinguish, and close all solenoid valves simultaneously, stop air feed.Detect button then and whether discharge, do not have not take any action under the situation of release when detecting button; When detecting under the situation that button discharged, judge whether tutorial light becomes green light Chang Liang by red light Chang Liang this moment, and when tutorial light becomes under the green situation, system enters automatic switchover mode, carries out relevant action, and saved system pattern and source of the gas number simultaneously; If tutorial light does not become green, then system enters the manual switchover pattern, carries out relevant action, meanwhile also saved system pattern and source of the gas number.Wait for key operation next time.
As shown in Figure 4, when system entered automatic switchover mode, system can close all solenoid valves, stops air feed, and check A one by one, whether B, C, D sensor have gas.When gas was arranged, green had gas tutorial light Chang Liang; During no gas, redness has gas tutorial light Chang Liang.Simultaneously, system can detect the pairing green of each steel cylinder one by one whether Chang Liang of gas tutorial light, and when the green of all steel cylinders had the gas tutorial light all to extinguish, system entered alarm mode; When detecting the pairing green of certain steel cylinder gas tutorial light Chang Liang is arranged, just open corresponding solenoid valve this moment, and the outside air feed in source.System enters the self check state subsequently, and 4 tutorial light of system are lighted one by one, and system can scan more than 3 times one by one then; If scan normally not enough 3 self check states above will be repeatedly one by one.After finishing the self check state, controller sends to PC with system model and current outside air feed source of the gas state, and this moment is the source of the gas of air feed normally, tutorial light: green light fast blink.
As shown in Figure 5, when system entered the manual switchover pattern, system can close all solenoid valves, stops air feed, and check A one by one, whether B, C, D sensor have gas.When gas was arranged, green had gas tutorial light Chang Liang; During no gas, redness has gas tutorial light Chang Liang.Simultaneously, system can detect the pairing green of A steel cylinder whether Chang Liang of gas tutorial light, and when the green of A steel cylinder had the gas tutorial light to extinguish, system entered alarm mode; When detecting the pairing green of A steel cylinder gas tutorial light Chang Liang is arranged, just open corresponding solenoid valve this moment, and the outside air feed in source.Controller sends to PC with system model and current outside air feed source of the gas state, and this moment is the source of the gas of air feed normally, and tutorial light: green light slowly glimmers.
As shown in Figure 6, when system entered alarm mode, system can close all solenoid valves, and simultaneity factor enters automatic switchover mode when can judge, when not entering automatic switchover mode, tutorial light: red light glimmers more slowly; When entering automatic switchover mode, tutorial light: red light comparatively fast glimmers, and warning light is flicker simultaneously also, and at this moment, whether system can press by the detection alarm key, does not press if detect alarm keys, and system will can not take any action; Press when detecting alarm keys, whether system can further detection send chimes of doom.If do not send chimes of doom, system will open chimes of doom automatically; If sent chimes of doom, system then can close chimes of doom.
Whether normal the utility model steel cylinder gas circuit switched system by determination of pressure sensor source of the gas air feed, again by controller opens or close solenoid valve, reaches the purpose that gas circuit is switched.And under the abnormal situation of source of the gas air feed, send chimes of doom.
Below the preferred embodiment of the utility model having been created specifies, but the utility model is created and is not limited to described embodiment, those of ordinary skill in the art also can make all modification that is equal to or replacement under the prerequisite of the utility model creative spirit, modification that these are equal to or replacement all are included in the application's claim institute restricted portion.
