Abstract
The utility model relates to a control system of rail transit station equipment monitoring information congestion. The control system comprises a control information array, a monitoring information array and a priority setting module, wherein the control information array and the monitoring information array are connected with the priority setting module respectively. Compared with the prior art, the control system has the advantages of ensuring priority processing of key data, ensuring fairness of data processing, effectively avoiding data congestion and assisting station schedulers to acquire site equipment fault conditions and related equipment control commands in time under the condition of limited bandwidth by introducing a PLDQ algorithm in the process of processing rail transit station equipment monitoring information and classifying the acquired information of the site equipment and the control commands according to different control strategies.
Description
Technical field
The utility model relates to field of track traffic, relates in particular to the congested control system of rail transit station equipment monitor message.
Background technology
Fast development along with urban track traffic, the monitored object of station equipment supervisory system is more and more, generally comprises: ventilation and air conditioning system, supply and drain water system, power and lighting system, escalator, vertical lift system, gate control system, screen door, closed guard gate, anti-flood etc.
Accordingly, the station equipment supervisory system is also increasing to the quantity of information of the collection of field apparatus and control, various data be aggregated in the supervisory system process and the supervisory system transmitting control commands in the process of bottom equipment, all might be because data congestion causes crucial device control instruction can't in time transmit with warning message.
How under limited bandwidth condition, guarantee in time assigning of crucial steering order,, become a problem demanding prompt solution with in time reporting of equipment alarm information.
Summary of the invention
The purpose of this utility model is exactly in order to overcome the defective that above-mentioned prior art exists, to provide a kind of high-efficiency reliable rail transit station equipment monitor message congested control system.
The purpose of this utility model can be achieved through the following technical solutions: the control system that the rail transit station equipment monitor message is congested, it is characterized in that, this control system comprises that control information formation, monitoring information formation, priority are provided with module, and described control information formation, monitoring information formation are provided with module with priority respectively and are connected.
Described control information formation is divided into the formation of control analog quantity information, the message queue of gauge tap amount.
Described monitor message formation is divided into monitor analogue quantity message queue, the message queue of monitoring switching value.
Described control information formation is the formation of storage equipment control command relevant information.
Described monitoring information formation is the formation of storage equipment state, warning relevant information.
Compared with prior art, the utility model has the advantages that by in the processing of rail transit station equipment monitor message, introducing the PLDQ algorithm, according to different control strategies to the processing of classifying of the Information Monitoring of field apparatus and steering order, under limited bandwidth condition, both guaranteed the priority processing of critical data, guarantee the fairness of data processing again, effectively avoided data congestion, assisted making station control in time to obtain field device failure state and relevant device control command.
Description of drawings
Fig. 1 is the synoptic diagram of the congested control system of rail transit station equipment monitor message of the present utility model.
Embodiment
Below in conjunction with specific embodiment the utility model is described further.
The control system that the rail transit station equipment monitor message is congested, this system comprise that control information formation, monitoring information formation, priority are provided with module, and described control information formation, monitoring information formation are provided with module with priority respectively and are connected.
Described control information formation is divided into the formation of control analog quantity information, the message queue of gauge tap amount.Described monitor message formation is divided into monitor analogue quantity message queue, the message queue of monitoring switching value.Described control information formation is the formation of storage equipment control command relevant information.Described monitoring information formation is the formation of storage equipment state, warning relevant information.
Groundwork principle of the present utility model is to classify at different on-the-spot I/O information, equipment state and device control order that priority processing is reported to the police and is correlated with.
Specifically, the station equipment supervisory system can be divided into rigid line I/O interface, low rate asynchronous serial communication interface and network interface with the interface type of the system or equipment of being monitored.
(1) rigid line I/O interface: adopt switching signal to come the state of indication equipment or the interface shape of control command, two kinds of switching value output and switching value inputs are arranged usually;
(2) low rate asynchronous serial communication interface: adopt RS485, RS422 or the interface standard realization of RS232 and the information transmission of equipment and system;
(3) network interface: the information transmission that adopts ethernet technology realization and equipment and system.
According to different data flows, the exchange message of these three kinds of interface types can be divided into monitoring information and control information again.
Wherein, monitoring information sends to the station equipment supervisory system by field apparatus, and control information sends to field apparatus by the station equipment supervisory system.
According to different data types, monitoring information and control information can be divided into analog quantity and switching value again.See accompanying drawing 1.
This method with field equipment data abstract be monitor analogue quantity, monitoring switching value and control analog quantity, gauge tap amount, and give different priority levels.The application higher to those qos requirements distributes high priority, otherwise then distributes low priority.
This method adopts independently control information formation (storage equipment control command relevant information) and monitoring information formation (storage equipment state, warning relevant information), and control information formation simultaneously and monitoring information formation are divided into switching value message queue and analog quantity information formation again separately.
