Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with embodiment, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Below in conjunction with drawings and the specific embodiments, application principle of the present invention is further described.
As shown in Figure 1, the machine room gate inhibition automatic alarm system of the embodiment of the present invention is primarily of switch contact 1, position relay 2, the time relay 3, state acquisition unit 4, machine room monitoring system 5, short message alarm module 6;
Switch contact 1 link position relay 2, position relay 2 tie-time relay 3, the time relay 3 connection status collecting unit 4, state acquisition unit 4 junctor room monitoring system 5, machine room monitoring system 5 connects short message alarm module 6.
Switch contact 1, is contained in the closed location of door, has "ON" and "Off" two states;
Position relay 2, is formed with switch contact 1 and links, and have maintenance function, and separately rear position relay coil is closed for two switch contacts, has electric current to pass through, gets final product triggered time relay;
The time relay 3, is connected with position relay 2, has clocking capability after energising, and after reaching the time of presetting, coil is closed has electric current to pass through, and gets final product trigger state collecting unit 4;
State acquisition unit 4, is connected with the time relay 3, has analog-digital conversion function, change electricity into digital quantity, thus judges that door is "ON" or "Off";
Transmission unit: netting twine or 485 buses;
Machine room monitoring system 5, by netting twine or 485 bus connection status collecting units 4, is a man-machine interactive system, gathers and converted to by system artificially discernible to important parameter each in machine room;
Short message alarm module 6, is connected with machine room monitoring system 5, and the warning information set in machine room monitoring system 5 is sent to appointment note number in real time.
When machine room door is "On" state, now position relay starts, position relay triggered time relay, start timing, when reaching the time of presetting " a " trigger state harvester after second, it is "On" state that state collecting device collects now machine room door, and is sent to staff mobile phone on to machine room monitoring system through short message alarm module by transmission unit;
If machine room door does not reach " a " second and just closes under "On" state, then the time relay not trigger state collecting unit.
As shown in Figure 2, the machine room gate inhibition automatic alarm method of the embodiment of the present invention comprises the following steps:
S201: the switch of door gets an electric shock and disconnects;
S202: position relay coil closes;
S203: time relay coil closes, starts timing; Reach a second, perform next step; Do not reach a second, then terminate;
S204: state collecting device display machines door "ON";
S205: machine room monitoring system collects machine room door "ON" signal;
S206: short message alarm module sends note to staff, the state of prompt machine door.
Principle of work of the present invention:
The present invention can not close within a certain period of time machine room door and reports to the police, and is sent to machine room operation maintenance personnel note by existing machine room warning system, reminds staff to determine the state of machine room door, guarantees the safe and stable operation of equipment in machine room.Machine room door access control alarm system is made up of position relay, the time relay, transmission unit and machine room warning system.When position relay judges that machine room door is "On" state, after certain time delay, report to the police and start.If position relay judges that machine room door is "Off" state within time delay, then warning system does not start.
After the switch contact disconnection of door of the present invention, loop is caused to disconnect, now position relay interior loop is closed causes second square frame inner looping energising, triggered time relay starts timing, return in the 3rd square frame when reaching setting-up time to be energized, now state acquisition unit receives signal, and exports machine room monitoring system to, and system is sent to staff place by short message alarm module.
The present invention is convenient to staff and is grasped machine room state in time, reduces the harm produced equipment in machine room, has ensured the safe and stable operation of equipment.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
