A systematic analysis of

• Engineering systems need to: control the throttle; of Smoke alarm and temperature monitoring (including the alarm, mute, reset, etc.); the five monitoring points of the curve shows the measured value;
• System No. + Address + Qualcomm fan = determine the specific equipment, (corresponding to a specific table, Party A to provide the drawings); one of its values for the system (1 ~ 4), address (1 ~ 264), Qualcomm Annona (1 ~ 4);
• Under the digital system for disaster prevention, Ltd. of Japan to the United States and GR-type host compound. Machine take the initiative to send the next bit of data, our driver is waiting to receive, when the following circumstances occur, the alarm count increased by 1:
  1. Breakdown;
  2. Greater than the alarm value;
  3. A device start-up;
  4. Control equipment, the response to return to the frame (through the values to determine ONOFF, equipment whether or not to open);
  5. Fixed temperature and Smoke to return to the measurement value (if there is no signal above the insert, then these measurements will be submitted to constant PC);
  All of these receive signals in a specific meaning, through the form below to judge (the specific needs of client communication, there is no description for the table of the reported information, we save the production of records, not to deal with):

• CTRL (system number, address, Tung Fan, type, category details, status, ONOFF value) as a special order, you can send commands through a command frame;

Analysis of the Second Configuration

Real-time Curve

On 1_17_1, 1_461_1, 3_84_1, 3_244_1, five address 3_262_1 cycle of data collection, and 5, the corresponding real-time curve of 5. (Can change the measurement of the address, but not to increase the drawing points)
Painting curve method:
Through the return of the measured values, save the record and draw curves, specific methods for:

• Order through equipment GETDATA (system number, address, Tong fan), we can continuously measured for a fixed data collection points, until once again through this command to change the measurement points; so that we achieve the five measurement points of the acquisition cycle;
• We issued an order equipment. If the alarm counts increased, to determine whether the corresponding measured values of the equipment and, if so, collect, save, and draw curve; and send GETDATA (system number, address, Tong fan), a collection of measurement points; If not, deal with the current signal, and maintain this equipment acquisition, until the adoption of the corresponding measured values, draw the corresponding point of the curve.

1. Data retention
   • Access real-time data collection preservation. (Changes in time to preserve a) (including time).
     - Drawing curves through data collection method, whenever an alarm when the count increased incident strategy, data Save;
   • Various steps: including the equipment to read and write (using the device command), for each screen in a variety of operational unit operations (on the valve opening, clearance)
     - Can be completed through the operation button switch output, the output of the pop-up box when prompted to avoid misoperation;
   • The preservation of police information: According to the type of up-channel acquisition, detailed category, the state value, and provided important data for the corresponding report to the police control, the same indicates that a corresponding alarm, then on the preservation of this set of data and the corresponding information together with the police to preserve
     - Need to determine the appropriate storage of the detailed description of the corresponding report to the police, described could be made so that Party A, we have to determine logical disk assignment.
2. Collection point alarm screen display of the animation, sound alarm:
   • Collection points to achieve corresponding color animation: Fault alarm display yellow, red emergency alarm. And an emergency alarm should sound output, the corresponding window in the corresponding operations have silencers.
     - Display a variety of alarm, I have made sample, you can communicate with customers.
3. Operating point of the screen:
   • Click on the operation point of first flicker effect that can operate at this time, and then through to the implementation of the other buttons (on / off), the abolition of such operations.
     - Through the visibility can be set to a time when the police should be shown flashes and buttons, so that a more refined picture, simple.

2, analysis of data objects

• 5 Acquisition of data concerns, preservation focus group to provide the data sources drawn curve

  Principle: because the digital system under the form of reporting (- that is, we issued an address concerns, and then automatically sends the next bit of data that point -), so that when we take into account the concerns of a message, issued focus of the next address, and so on.

• Alarm handling:

  Principle:
  Alarm Equipment - by the system automatically on the information made the decision, and the category (data4), detailed categories (data5) and status (data6) related.

  Data Objects alarm - we pass: fire alarm, hand-reported alarm, gas alarm, intelligent detector failure, the end of the machine failure, sensor failure and gas equipment failure seven numerical data object, stored alarm Synthesis address (for example: System No. 1 Address No. 1 fan of 11 pass fire equipment, then the synthetic address: 10111, and synthetic address> = 10000), the object properties for the upper limit of alarm alarm alarm value is 10000. Alarm object under normal circumstances, the value is 0, when the equipment alarm generation, alarm synthetic object is given the address, so the police have a data object.

  Automatically open the window where the alarm point - the police have, through the police point of address, use odbc functions, where we can find the window, and then open.

  Animation-driven alarm points - such as fire alarm connection point flashing animated conditions are as follows: fire alarm = Synthesis address. The specific address such as system 11 No. 1 Fan 1 Qualcomm fire equipment, the flashing Smoke conditions are as follows: fire alarm = 10111
