Description
Technical field
The present invention relates to monitoring of tools technical fields, specifically provide and a kind of judge parking space state based on OPC protocol
System and method.
Background technique
Computer has many advantages, such as that information memory capacity is big, and user's acquisition information is convenient and efficient, is widely applied.It is special
It is not in recent years, with the rapid development of economy, computer application field is more and more extensive, wherein in device status monitoring
That applies is also more and more.
In recent years, with the continuous development of society, the raising of economic level, people's lives level have very big change
It is kind, people not only pursue it is in life have enough to eat and wear, also more pursue in life comfortable.Automobile can increase the convenient of people's appearance
Property, the free walker of trip is improved, and can be improved the comfort level during people's trip, city vehicle is more and more.Due to
The problem of increase of vehicle, the demand to parking stall is increasing accordingly, and bring is exactly parking stall therewith.It stops
When, since vehicle is excessive, car owner will just have found to have stopped on parking stall behind the parking stall Che Kaizhi, can only look for others again
Parking stall is stopped.Since parking stall is not able to satisfy the demand of vehicle, such people will increase on down time in trip
Add long time, the experience for driving to go on a journey this reduces people also will increase vehicle and gather around simultaneously because down time is too long
Stifled situation occurs, and wastes the time of the big handle of car owner to stop.It therefore, is to guarantee vehicle whether the normal of parking stall, failure, free time
The basis normally parked has great importance to the drive experience of trip of people is improved.
Summary of the invention
Technical assignment of the invention is that in view of the above problems, the shape on parking stall can be provided at any time by providing one kind
State quickly searches out idle parking stall convenient for car owner, and improve parking efficiency is based on what OPC protocol judged parking space state
System.
The further technical assignment of the present invention is to provide a kind of method that parking space state is judged based on OPC protocol.
To achieve the above object, the present invention provides the following technical scheme that
A kind of system judging parking space state based on OPC protocol, including parking space detector and parking stall management unit, institute
Stating parking stall management unit includes data extraction module, data analysis module and data display module, data extraction module and parking stall
Detector communicates, and data analysis module is communicated with data extraction module, and data display module is communicated with data analysis module
Letter.
This judges the system of parking space state based on OPC protocol, distributes unique number to each parking stall, passes through parking stall
Number, configuration parking space detector and parking stall management unit, parking stall management unit detects the status information of parking space detector, according to sound
The information answered is analyzed, to judge the idle state of parking stall.
Preferably, the parking space detector uses infrared sensor or contact push switch.
Preferably, the data extraction module is interactively communicated by using OPC agreement with parking space detector, to parking stall shape
State data are periodically extracted.
The data extraction module writes OPC client, accesses OPC server, inquires parking stall by parking stall numbering, just
The status information of parking space detector response can be read.
The read-write for carrying out data is standardized using OPC DA, is obtained using Custom interface, Custom interface includes three objects:
OPC Server,OPC group,OPC item.OPC Server includes multiple OPC group, and OPC group also includes multiple
OPC item.It is to be operated as unit of OPC group when carrying out reading and writing data.

The C/S model of type is completed for the driver of hardware device by hardware vendor, and the Server of unified OPC interface standard is provided
Program, software vendor, which need to only write Client program according to OPC standard interface and just access Server program, to be written and read, Ji Keshi
Now with the communication of hardware device.
OPC DA:DataAccess agreement is most basic OPC agreement.OPC DA server not storing data itself, only
It is responsible for the current value of display data collecting point.A refresh interval can be set in client, this value is periodically flushed.
Preferably, the data analysis module passes through the status information of the parking space detector checked out, parking stall is analyzed
State.
Preferably, parking space state of the data display module by analysis data, at the end Web of parking stall management unit
Show each parking space state.
A method of parking space state is judged based on OPC protocol, method includes the following steps:
S1, it is numbered for the configuration of each parking stall is unique；
S2, a parking space detector is configured for each parking stall, parking space detector timing is current to parking stall management unit feedback
Status information；
S3, parking stall management unit obtain the information of parking space detector feedback, analyze parking space state；
S4, parking stall management unit are by analyzing obtained parking stall numbering, the displaying of parking stall idle state in parking stall management unit
The end Web.
Preferably, parking stall management unit described in step S3 includes data extraction module, data analysis module and data
Display module, data extraction module are communicated with parking space detector, and data analysis module is communicated with data extraction module, data
Display module is communicated with data analysis module.
Preferably, the data extraction module is interactively communicated by using OPC agreement with parking space detector, to parking stall shape
State data are periodically extracted.
Preferably, the data analysis module passes through the status information of the parking space detector checked out, parking stall is analyzed
State, data display module show each parking stall shape at the end Web of parking stall management unit by the parking space state of analysis data
State.
Preferably, parking space detector described in step S2 uses infrared sensor or contact push switch.
Compared with prior art, of the invention to judge the method for parking space state with following prominent based on OPC protocol
The utility model has the advantages that based on OPC protocol should judge that the method for parking space state can detect the state of each parking stall in real time, sentence
Whether disconnected parking stall normal, parking whether etc. parking space states information, provide the monitoring of parking space state for parking lot management personnel, again
Parking stall is quickly found for vehicle and provides convenient method, and there is good application value.
