Automatic monitoring instrument accessory driver
The monitoring device can detect the concentration of ammonia nitrogen in wastewater treatment process online. It utilizes new gas and liquid transmission technologies and high-performance colorimetric measurement methods, providing reliable and accurate ammonia nitrogen detection results with low maintenance. Due to its compact structure and affordable price, it can replace existing high maintenance analyzers based on electrochemical principles. At the same time, this analyzer can also meet the high reliability and low-cost requirements of various users for instruments.

Below is an introduction to the operation method of the monitoring device:

1. Sample

Laboratory samples should be collected in polyethylene or glass bottles and analyzed as soon as possible. Otherwise, these samples should be stored at 2-5 ℃ before analysis. Acidizing the samples with sulfuric acid to pH<2 can help preserve the samples. However, the acidified samples may absorb ammonia from the atmosphere and may be contaminated, so precautions should be taken to prevent contamination.

2. Sample

The volume is 20ml and can be used for the determination of ammonia nitrogen concentration below 1mg/l. For samples with higher concentrations of ammonia nitrogen, a small amount of appropriate sample can be taken for determination. If the experimental sample contains suspended solids, it should be clarified or filtered by gravity through a cleaned glass bottle fiber paper before sampling. The water sample can also be distilled.

3. Formation of absorbing compounds

Add 2.00ml ± 0.05ml of color reagent to the sample processing bottle after constant temperature and mix well. Then add 2.00ml ± 0.05ml of sodium dichloroisocyanurate solution and mix well. Shake the sample processing bottle thoroughly and place it on a digestion apparatus at a constant temperature of 50 ℃ for constant temperature heating.

4. After maintaining a constant temperature for at least twenty minutes, remove the sample processing bottle from the digester and measure the absorbance and concentration using a colorimeter.

5. Calibration and curve drawing

Add standard solutions with ammonia nitrogen concentrations of 0.5mg/l (0, 2.00ml, 5.00ml, 10.00ml, 20.00ml) to a set of 5 50ml sample processing bottles. If necessary, dilute with water to 20.0ml ± 0.5ml. Process according to 7-2 and 7-3, subtract the absorbance value of the blank test from the absorbance values measured in each calibration solution, and draw a curve of absorbance value versus ammonia nitrogen mass. This line should be a straight line and pass through the origin.

　　Automatic monitoring instrument accessory driverBasic function

Driver broadly refers to the hardware that drives a certain type of device. In the field of computer science, a drive refers to a disk drive. A storage area formatted with a drive letter through a file system. The storage area can be a floppy disk CD、 Hard drives or other types of disks. Click on the corresponding icon in Windows Explorer or My Computer to view the contents of the drive. The driver is located in the middle of the main control box (MAINCONTROLER) -->driver -->motor during the entire control process.

The main function is to receive signals from the main control box, process the signals and transfer them to the motor and related sensors, and provide feedback on the motor's operation to the main control box.

　　Driver monitor accessoriesIntroduction

To understand the information on floppy disks and CDs, it is necessary to insert them into the floppy disk drive and CD drive respectively, so that the computer can recognize and process the data information on them.

The floppy disk drive and optical disk drive are both located in the chassis, with only their 'mouths' exposed, ready to' eat 'floppy disks and optical disks at any time.

As for the hard drive, since it is non removable, it is fixed within the drive, which means that the hard drive and hard drive are integrated. When inserting a floppy disk into a floppy disk drive, pay attention to the orientation. For a 3.5-inch disk, the pivot should face downwards and the metal plate should face forward. If you hear a 'click' sound from the eject button below the drive port, it means that the floppy disk is inserted properly.

When removing, you should first press the eject button, and the floppy disk will automatically eject a portion. Then, remove the floppy disk. Nowadays, fewer and fewer people use 5.2-inch disks, and 5.2-inch floppy disk drives are rarely installed on computers. It is worth noting that there is a small indicator light above or below the floppy disk drive. When the indicator light is on, it indicates that the computer is reading or writing to the floppy disk in this drive. The indicator light for the hard disk drive is also located on the front panel of the motherboard. When the indicator light is on, it indicates that the computer is reading or writing to the hard disk.

When the drive indicator light is on, do not remove the floppy disk from the corresponding drive or shut it down, otherwise it may cause damage to the disk.

A computer may have more than one software and hard drive, how to distinguish them? We adopt the method of naming the drive. The names of drives are represented by individual English letters, with A and B representing floppy disk drives, C, D, and E representing hard disk drives, and optical disk drives generally represented by the letter H. In this way, we have what we often refer to as' A drive, B drive, C drive, D drive '. Each computer usually only has one optical drive, so it is often abbreviated as' optical drive'.
