Embodiment
Below in conjunction with specific embodiment, further illustrate the present invention, should understand these embodiment only is used for explanation the present invention and is not used in and limits the scope of the invention, after having read the present invention, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present invention.
A kind of river course check gate operation monitoring system comprises data acquisition and treatment facility, operation monitoring and accident alarming equipment, control and conditioning equipment, data communications equipment.
1, data acquisition and processing
(1) collection and the processing of digital quantity (analog quantity): the cycle collection is carried out in parameter, the off-limit alarms such as water levels of upstream and downstream, electric current, voltage, formed real time data and deposit real-time data base in after processing finally by format.
(2) collection of switching value and processing:
To switching value signals such as the trouble-signals such as motor overload, motor start-stops, computer automatic control system should be able to respond rapidly these signals and make reaction and the automatic operation of a series of necessity with interrupt mode.Interrupt switch amount signal is input as passive contact input, and interrupt mode receives;
To the non-interrupt switch amount signals such as position signalling that all kinds of fault-signals, utility appliance operating state signal, manual automated manner are selected, computer supervisory control system is regular scanning to the acquisition mode of these signals.To the processing of signal comprise photoelectricity isolation, the anti-shake processing of contact, hardware and software filtering, compensation reference time, data validity rationality judge, start the correlative function (as start sequential accident recording, send out the accident alarming sound equipment, picture is released automatically and auto stop etc.), deposit real-time data base in after processing finally by format.
(3) accumulative total of pulsed quantity and processing: the acquisition process of pulsed quantity comprises the anti-shake processing of contact, the judgement of data validity rationality, scale transformation, error-detection error-correction processing, after processing, format deposits real-time data base in, and also can be directly by the serial communication collection.
(4) switching value output: refer to various operational orders, computing machine should carry out verification before these signals of output, can deliver to topworks through judging after errorless.For guaranteeing electric independence and the accuracy of signal, switch output signal also should be isolated through photoelectricity, sends after the anti-shake processing of contact.
(5) signal quantity and setting state: the semaphore that the signal that causes owing to Equipment is made mistakes and will be carried out where necessary artificial setting value analyzing and processing, computer automatic control system should allow operator and system operators that it is manually set, and when processing, they are equal to the normal signal that gathers and treat, computer automatic control system can be distinguished them and provide corresponding sign.
2, operation monitoring and accident alarming
(1) operation real time monitoring: computer automatic control system can make the operations staff by screen the running status of each main equipment of hinge, parameter and each gate be carried out real time monitoring.All contents that will monitor comprise operation and the stoppage in transit situation of current each equipment, and each operational factor is shown in real time.
(2) parameter off-limit alarm record: computer automatic control system will be monitored some parameter and computational data, can preset its limited field to these parameter values, will be correspondingly processed in limited time when they are out-of-limit and multiple.These processing comprise off-limit alarm, more multiple automatic demonstration, record and printing of prescribing a time limit; Also should carry out the data storage of out-of-limit rear extremely multiple limit and call demonstration for important parameter and data; Start the correlative analytic function, do the failure cause prompting, for the warning that will warm up of some important parameters.
(3) fault journal: when the operation troubles situation occured, automatic control system should be immediately with interrupt mode response and automatically demonstration, record and printing problem title and time; Record and print the action situation of relevant device, automatically release dependent picture, make analysis on accident cause and prompting disposal route, system should be able to record the accident that occurs and the action situation of equipment by the sequencing of its generation.
(4) malfunction shows record: computer automatic control system is each fault status signal of scanning regularly, in case occur shape become will be on screen instant playback out, simultaneously record trouble and time of origin thereof, and use audio alert.System is no more than 2 seconds to the polling cycle of fault status signal.
(5) emergency review and correlative record: when having an accident, gather the quantity of state of each equipment and send the pulpit by each field control unit, finish event sequence ordered arrangement, demonstration, printing and file.The resolution of the record of each event and print point title, state description and markers, record is not more than 2ms, should be able to the record accident occurs front 10 seconds and the situation of change of important real-time parameter in rear 20 second time.The operations staff can call, shows or print these data.
