Along with monitoring configuration software in all the various trades' and occupations' widespread application, the personnel which many coal mines safety in production research institute, the design institute and other is engaged in the coal mine safety in production in order to enhance the project development the efficiency, all hoped can directly use configuration software to carry on the coal mine safety in production the management. But because the coal profession has the particularity, for instance may the dynamic additions and deletions substation, and so on the ultra time limit directly carry on the control in the gas density and so on, also gave monitoring configuration software to set the new request.

These new requests include:

* Software may when the movement dynamic increase or deletion position number. Only has software when the movement may the dynamic additions and deletions position number, only then be able to satisfy in the coal production each gathering quantity dynamic change.
* Software may when the movement dynamic change actuation connection. Only then, can change the gathering data along with the demand change the order.
* Software may when the movement the dynamic increase picture, draws up each kind of chart Yuan, carries on each kind of animation connection. Also only can display like this under equipment changing in software by the graph way.
* (For instance gas density) ultra limits after certain quantities not only can carry on reports to the police, moreover also may carry on the power failure control, the linkage control and different controls and so on the control work.

In order to meet the general coals safety in production worker's need, the purple golden bridge company took the lead to expand the monitoring configuration software function above, already definitely could satisfy several requests. Under on introduces purple golden bridge software by an application demonstration in the coal mine safety in production aspect application.

This system is composed by the under several parts:

* Scene equipment

Each kind of sensor, the control valve, the switch and so on a measuring appliance, carries on the control and the management by the substation. Their data compiles the substation, issues to their control command by the substation.

* Substation

The control station, completes the control function by the monolithic integrated circuit or PLC, according to function difference, also divides primarily the substation and the inferior substation two kinds. It can complete from following measuring appliance gathers the data, and according to the limiting value which beforehand establishes carries on reports to the police with the power failure control, is one of main control mechanisms. But it only can analyze under the control current substation an all measuring appliance data, is unable to carry on the generalized analysis to all measuring appliances, also is unable to complete the different power failure function.

* Server

The computer server, the above moves purple golden bridge monitoring configuration software, with under each substation composition network. Purple golden bridge software through network from under substation gathering data, thus can complete the data centralism processing, also may carry on the synthesis to all data the analysis. Purple golden bridge software the control command which needs to carry on through the network transmits to under each substation, again goes to a further control measuring appliance by various substations.

In purple golden bridge software movement below time can complete the work:

* Substation initialization

Because each substation has not been allowed to dispose contact surface, therefore the substation disposition work completes by the server. Moves in the system, may increase, the deletion in purple golden bridge software or change the substation. Simultaneously also may revise each substation the disposition, for instance each sensor type, measuring range, limiting value and so on. After changed the substation disposition, purple golden bridge software can through the network to the corresponding substation transmission initialization order, the initialization substation each establishment quantity.

* The cycle gathers various substations the data

In carries on the initialization after the substation, purple golden bridge software can the periodic gathering each substation data. These data including each sensor simulation quantity and switch quantity, each control condition. Moreover also has each substation the middle control condition, in order to the server and the substation carry on control synchronization, like this works as the hand-off control way, can the correct smooth cut.

* To scene equipment hand control

Moves in the system, the operator may establishes through the purple golden bridge software monitoring contact surface certain control valves or the sensor as the hand control condition, then to scene equipment transmission hand control order. The control command first transmits through the network to each substation, then carries on the concrete control by each substation to a measuring appliance.

* Procedure control

The procedure control may complete with the substation primary control logic same control function. When system movement assigns when the purple golden bridge contact surface certain sensors is at the procedure control condition, the server can inform the corresponding substation, the substation to be able to cut the corresponding control condition. This time, regarding is in under the procedure control each sensor, the substation no longer carries on any logical control, completely comes to this sensor control command by purple golden bridge software through the network to issue. The procedure control is one kind of backup control, has the problem in the under substation control logic time, may cut the procedure to control replaces the substation to carry on the control. After the question is solved, gives once more the domination transmission the corresponding substation. In the usual situation, is normal when following substation control, should by the under substation but not be purple golden bridge software exercises the power failure control logic. Because the server control needs to rely on the network the reliability, simultaneously controls also can have the time delay which the network transmits.

* Different controls

Because each substation is unable to act according to other substations the condition to carry on differently controls, therefore the different control section must complete by purple golden bridge software. So-called different controls, is acts according to a substation certain quantities conditions to control other some substations certain controllers. For instance after examines ultra limits to a substation gas sensor data, not only needs immediately to open this substation some equipment to increase ventilates, but also must open the neighboring substation equipment assists to reduce the gas density.

* Reports to the police the prompt

After purple golden bridge software discovered surpasses the hypothesis from some substation gathering data the limiting value, can produce corresponding reporting to the police, and has reports to the police the sound prompt. In order to prompt reminder operator's unusual occurrence. Purple Jin Qiaohuan has provided the retrieval function which the history reports to the police, may inquire wilfully one day-long to report to the police the record.

* The data compiles, the demonstration and the inquiry

After various substations data gathering server, purple golden bridge software may through the graph way, the animation way demonstrate each substation the sensor condition. Also may through the report form form each substation data centralism demonstration and the analysis. Meanwhile gathers from the substation to the data also may carry on the preserved history, like this may comes the logarithm through the historical report form or the historical tendency according to the change tendency carry on the analysis.

May know by the above introduction that, in this system has the hand control, the procedure control, the different control and the substation local as follows controls the altogether 4 kind of controls, the substation to their processing way:

* The hand control is most superior

When some sensor is in the hand control, then not corresponding other any controls, like this appears the breakdown when the system control logic, may temporarily complete the overall system through the hand control the control.

* The procedure controls next

When some sensor is in the procedure controls, the sensor control condition by the procedure control and different controls together decided, namely these two kind of controls so long as has a need power failure, then carries on the power failure control, otherwise carries on relegrams in reply the control.

* Local controls inferiorly

When some sensor is in the substation local controls, the sensor control condition by local controls with differently controls together decided, namely these two kind of controls so long as has a need power failure, then carries on the power failure control, otherwise carries on relegrams in reply the control.

Through the above introduction, we can see, the overall system controls by three decided. In the usual situation, the system local controls by the substation processes, when local controls appears the breakdown may cut the procedure to control replaces, if the procedure control also appeared the breakdown, then also may cut the hand control to complete the control function.

The next chart is time the overall system movement contact surface, above the part is the function menu choice part, left side the part is the further function choice menu, right flank the part is the picture demonstration area.

Under a brief introduction system movement each part:

* The system lands

When enters, needs to carry on lands, only had has input the correct user name and the password, only then was allowed to enter the system.

* User management page

If the current user has the enough jurisdiction, then may enter the user management page, increases the new user or the revision deletes the existing user.

The user altogether has three kinds:

(1)th, the highest system manager, he may not delete, also only has him only then to be allowed to found or to revise other system managers, he may enter any window, may carry on any operation.

(2)th, the ordinary manager, he may not found or change other any managers, but may found the operator user, he also may enter any window.

(3)th, the operator, he cannot found other any users, but cannot enter the system disposition window, only can examine the picture or the retrieval data.

* Measuring point definition page

It definition which including the substation definition, the simulation quantity and the switch quantity definition, the control channel definition as well as different controls. The system can act according to the new definition the substation or the channel founds the new position number, and simultaneously automatically carries on the actuation connection for the new foundation position number, the final system can the automatic use recent information initialization corresponding substation. After initialization substation, the system can automatically gather this substation the data, and carries on reports to the police with the control function. Moreover in order to facilitate the channel the definition, the system provided has simulated the sensor and the switch quantity sensor definition, like this when defined the channel only needed to choose was correct already has defined the sensor type, the system has been able automatically to take the corresponding sensor to lack the province to suppose the value, reduced the work load which the channel defined.

* Trend analysis

In this page may most examine 8 channels the data change conditions, may put the different substation channel data tendency in the same place carry on the comparison. May wilfully cut the outset time, the time scope, also may the free enlargement curve examine more details.

* Reports to the police the inquiry

In the current page may examine current occurs real-time reports to the police, also may in the current page confirm already occurred reporting to the police.

Simultaneously also may examine wilfully a day-long history reports to the police. Regarding reporting to the police which retrieves, may print the careful analysis.

* Real-time report form and historical report form

May in the current page retrieval real-time data report form, if on the chart will show, has reports to the police or the power failure channel can demonstrate by the different color. May examine the channel in the real-time data report form the current value, also may examine each substation in the real-time data report form the communication condition.

Also may retrieve each kind of historical report form in the current page, for instance 5 minutes simple points daily papers, 24 hours data report forms, as well as each kind of comprehensive report form.

* Picture edition page

May Yuan and a complex chart Yuan kneading board comes in this page through the left side Jan sketch map in the picture to found the new chart Yuan. Double-clicks the corresponding chart Yuan then to choose the connection the channel, the system can reflect the corresponding channel by the animation form the data. For instance ventilator revolving, air throttle changing color, the fluid position fluctuation and the pipeline flow and so on. May facilitate in this page carries on changes each chart Yuan position, the edition size, work and so on revision writing. The current page only has the system manager only then to be allowed to enter.

* Real-time picture

This picture demonstrated the picture edition page produces picture, but may not carry on the edition, the operator user may enter the current page.

* Under the data sets

May establish the substation in the current page certain coefficients, may change some substation the control channel control mode, may transmit the hand control order, also may complete establishes tired measurement function and so on automatic clear zero.
Through the above introduction, we may see, passes through the purple golden bridge company's endeavor, purple golden bridge monitoring configuration software already definitely was allowed to satisfy the coal safety in production monitoring the need, used purple golden bridge software to be able greatly to save the development the time, reduced the development the work load. Believed through in the coal safety in production aspect unceasing application, purple golden bridge software will be able more perfect, to be more convenient specialized.
