Abstract
The invention discloses a method for replacing a PLC (Programmable Logic Controller) by monitoring devices on the basis of comprehensive monitoring of a large lag system. The monitoring devices have the characteristics of high cost performance, high electromagnetic compatibility level, high protection and abundant input output but have no unique quick sequential control for scanning according to a time slice of the PLC. The comprehensive monitoring is interface-friendly and a control strategy can be easily modified, so that using the comprehensive monitoring, which replaces the main CPU (Central Processing Unit) of the PLC, for monitoring the monitoring devices, which replace the PLC for monitoring, is a reasonable selection. A large lag inertial system does not require the unique quick sequential control for scanning according to the time slice of the PLC, so that the widely used monitoring devices without such a function can be adopted. The monitoring devices are adopted, so that the system architecture is simplified. Compared with the PLC, the monitoring devices have higher cost performance.
Description
Technical field
The present invention relates to a kind of implementation method that can be applied to the monitoring of large time delay Great inertia system, belong to system control neck
Domain.
Background technology
Monitoring of the large time delay Great inertia systems such as traditional subway building to geomantic omen electricity is based on BAS (Building
Automation System, hereinafter referred to as BAS) system using PLC (Programmable Logic Controller, below
Abbreviation PLC) it is monitored, referring to Fig. 1, the strategy of this monitoring is realized in the main CPU unit of PLC to system diagram, then is led to
Cross the main CPU unit multiple I/O cells of monitoring, realize to geomantic omen electricity there is a problem of it is as follows：1) BAS aspects modification control strategy
It is inconvenient；2) more complicated control strategy is difficult to carry out；3) interface is unfriendly；4) without other professional information, such as room
The information such as outer humiture, the volume of the flow of passengers, train travel interval, the volume of the flow of passengers, festivals or holidays, it is difficult to make scientific and reasonable control plan accordingly
Slightly；4) it is difficult to just collect control effect, for example power consumption, the humiture at whole station etc.；5) it is difficult to enter control effect
Row compares, for example, compare the energy-saving effect of certain period of certain station day and certain day before certain period；6) so be difficult to it is right
Control strategy is optimized；7) optimization of control strategy is updated during needs re-download PLC, it is difficult to entered by daemon software
Row is either automatically or manually completed；8) system architecture is complicated；9) PLC prices are higher；10) system such as subway building is typical big stagnant
Great inertia system afterwards, the response speed to controlling is less demanding, it is not necessary to PLC it is distinctive according to timeslice be scanned it is quick
Sequential control；11) typical PLC is minimized due to pursuing, and is outputed using transistor output, causes output capacity less, so
Generally need to be installed outside it relay with driving equipment, cause system complex and cost to improve.
The content of the invention
To solve the above problems, the present invention provides a kind of use based on comprehensively monitoring for being applied to large time delay Great inertia system
Measure and control device replaces the method for PLC.
A kind of Large-lag System based on comprehensively monitoring replaces the method for PLC with measure and control device, the measure and control device for using
Including comprehensively monitoring daemon software, the server of operation comprehensively monitoring daemon software, interchanger, controlled measure and control device, its feature
It is to comprise the following steps：
1) the controlled measure and control device of software supervision is set by comprehensively monitoring；Server is connected with interchanger；Measure and control device with
Interchanger is connected；
2) measure and control device is controlled without the distinctive rapid sequentials being scanned according to timeslice of PLC；
3) measure and control device can exchange information with the comprehensively monitoring daemon software for being connected to interchanger, also can be mutual with interchanger
Exchange information；
4) when comprehensively monitoring daemon software communicates normal by interchanger with measure and control device, by comprehensively monitoring daemon software
Under send instructions；When comprehensively monitoring daemon software and measure and control device communicating interrupt, work is cooperateed with by interchanger between measure and control device
Make；When also communicating interrupt between measure and control device, measure and control device carries out autonomous work according to the pattern and timetable downloaded.
Wherein, communication modes use ethernet communication, and the control for needing quick response is entered row information and handed over using goose
Mutual and control.
The systems such as subway building are typical large time delay Great inertia systems, it is not necessary to which PLC is distinctive to be carried out according to timeslice
The rapid sequential control of scanning, therefore using the measure and control device without such function, therefore can use this method, i.e.,
The method of PLC is replaced with measure and control device based on comprehensively monitoring.Herein, the host CPU of the PLC of traditional BAS system is also eliminated
The equipment of unit this level, the measure and control device being monitored to equipment such as geomantic omen electricity by comprehensively monitoring direct monitoring.
The beneficial effect that the present invention is reached：
Because comprehensively monitoring has converged a large amount of specialties, mass data, such as outdoor temperature humidity, between the volume of the flow of passengers, train travel
Every information such as, the volume of the flow of passengers, festivals or holidays, it is thus susceptible to make scientific and reasonable control strategy accordingly, it is easy to control effect just
Collect, such as power consumption, the humiture at whole station etc., it is easy to be difficult to be compared control effect, for example, compare certain car
Stand the energy-saving effect of certain day certain period and certain day before certain period, it is easy to which control strategy is optimized, it is easy to it is automatic or
Person optimizes to control strategy manually, it is easy to implement complicated control strategy, due to friendly interface, it is easy to modification control plan
Slightly, it is a kind of therefore the measure and control device being monitored instead of PLC to be monitored instead of PLC main CPU units using comprehensively monitoring
Rational selection.Large time delay Great inertia system, it is not necessary to which the distinctive rapid sequentials being scanned according to timeslice of PLC are controlled,
Therefore can be using the wide variety of measure and control device without such function of acquisition.Using measure and control device, PLC master is eliminated
CPU element, simplifies system architecture.Because there is measure and control device capacity relay to export, no longer as PLC needs external relay
Device driving equipment, also simplify system architecture.Measure and control device has cost performance higher than PLC.
