Embodiment
Below in conjunction with accompanying drawing the present invention is described in further detail.
This specific embodiment only is an explanation of the invention; it is not a limitation of the present invention; those skilled in the art can make the modification that does not have creative contribution to present embodiment as required after reading this instructions, but as long as all are subjected to the protection of Patent Law in claim scope of the present invention.
As shown in Figure 1, a kind of supervising device of producer gas generator comprises platinum rhodium thermocouple 1, the pressure unit 2 that is used to detect gaseous tension in the producer gas generator that is used to detect temperature in the producer gas generator, infrared probe 3 and Siemens S7-300, industrial computer 4, display 5 and the audible-visual annunciator 6 that is used to detect the coal dolly.Described Siemens S7-300 comprises central processing unit 7 and input, output module 8, and described load module comprises AI module and DI module 9; Described pressure unit 2 by many mouthfuls of contact cables connect with a described AI module 10a, described platinum rhodium thermocouple 1 by many mouthfuls of contact cables connect with described the 2nd AI module 10b, described infrared probe 3 connects with described DI module 9 by many mouthfuls of contact cables, described audible-visual annunciator 6 connects with described output module 8 by many mouthfuls of contact cables, described display 5 connects with described central processing unit 7 by many mouthfuls of contact cables, and described industrial computer 4 connects with described display 5.
Described platinum rhodium thermocouple 1 has a plurality of, a bottom that is arranged on producer gas generator, be used to detect the water vapor that enters producer gas generator and the temperature of Air mixing gas, a gas exit place that is arranged on the producer gas generator top is used to detect the gas temperature at gas exit place; Described pressure unit 2 has a plurality of, a bottom that is arranged on producer gas generator, be used to detect the water vapor that enters producer and the pressure of Air mixing gas, a gas exit place that is arranged on the producer gas generator top, be used to detect the gas pressure at gas exit place, a drum place that is arranged in the producer gas generator is used to detect the pressure in the drum.
Development of man-machine interface mainly comprises hardware configuration and two aspect contents of variable-definition.KingView is to realize by the management to logical device name to the management of equipment, specifically be exactly that each actual I/O equipment all must be specified a unique logical name in KingView, this logical device name just corresponding the manufacturer of this I/O equipment, physical device title, device talk mode, device address, with the information contents such as communication modes of host computer.KingView provides a large amount of dissimilar drivers, and the engineering staff gets final product according to the I/O choice of equipment corresponding driving program of own actual installation.The equipment of native system is provided with as follows: Siemens S7-300---many mouthfuls of contact cables---COM2 mouth---address 2.2.
The data variable attribute of KingView is made up of base attribute, alarm configuration, three property pages of recording configuration.Adopt this card form way to manage, the user is as long as use the attribute tags at mouse-click card top, and then this attribute card is effective, and the user can define corresponding attribute.For example: variable name TE101; Types of variables: I/O integer; Connection device: S7-300; Register: DB40.16; Data type: SHORT; Read-write properties: read-write; Minimum value: 0; Maximal value: 1600; Frequency acquisition: 1000 milliseconds; Report to the police and define: be low by 1100, high by 1300; Record: data variation record; Variable description: 1# producer gas outlet temperature.Then this variable each second slave controller analog quantity load module address is DB40.16 input point reads the input value of thermopair, and is presented on the man-machine interface.Data are 0～1600 correspondence, 4～20mA.
The output of reporting to the police utilizes the command language in the KingView software to write.In " picture properties-command language ", write command language, and carry out corresponding function connection.For example, certain variable runtime value being carried out limit value reports to the police.With PE105 (drum pressure) is example, and it is 500pa that safety value is set, and actual value surpasses 500pa and then sends sound and light alarm.
Then command language is as follows:
This Zhan Dian of this Zhan Dian of IF (PE105＞=PESET)
{
This Zhan Dian of BitSet (Alarm, 0,1);
}
This Zhan Dian of this Zhan Dian of IF (PE105＜PESET)
{
This Zhan Dian of BitSet (Alarm, 0,0);
}
Wherein variable PESET is the drum pressure alarm setting value, can artificially set and revise on man-machine interface.Variables A larm is a certain position of M register in the controller, and it is put 0 or put 1 and come the guide sound light crossing-signal, and the control of alarm is finished by director demon.
Functional pictures such as the curve inquiry of parameter, table lookup utilize KingView to carry control exploitation.The KingView control is similar to the combination pixel in appearance, only needs it is placed on the picture, disposes the attribute of control then, carries out corresponding function and connects, and control just can be finished complicated function.
