- Q: There is no monitoring software, you can monitor the computer's switching time and operating records
- Now most of the domestic companies are using the company [network dog] monitoring software, it can easily achieve QQ, MSN chat content monitoring, Internet monitoring, send and receive e-mail content monitoring, screen monitoring, desktop monitoring, but also filter URL blacklist, prohibit the game entertainment software to run, manage the use of mobile hard disk U disk drive, break through a variety of arp firewall control network any one of the machine speed and traffic. The The Monitoring is so simple that the management network is so easy. Can be said that the current domestic most professional, the most simple operation of the network management software! The If you want to know more, you can go to Baidu search under the network, is a red software, hoping to help you! Please adopt! Thank you ? The answer was adopted by users
- Q: It is best to have pictures, the effect is to achieve this, power, light does not shine, press the button switch, 15 minutes after the light, then press the switch, the lights and then off, do not press the lights immortal. Can not achieve such a procedure. The relay is energized.
- When the button is pressed, the relay is energized, open the contact self-locking button, the relay has been power, delay 15 minutes later, the delay contact action, light, then open the contact action to make the relay power failure, Back to the original state, the light has been bright. When the button is pressed again, the relay is energized, the light is off, the delay is bright and so on.
- Q: Duty cycle and switch cycle, the switch tube opening time, the relationship between the three
- Ton = 1 / f * d So your understanding is right The turn-on time of the switch in one cycle = D * cycle
- Q: What is the file in the computer that records the time of the switch?
- You can by right-click on my computer to select the management will open the computer management, click inside the event viewer and then click on the system. So you will see the computer you want to boot, shutdown and other events of the incident. Above hope to help you.
- Q: How can we set up the morning 6 o'clock in the morning how to set up the computer when the machine automatically boot ah How to set it to automatically shut down? Thank you
- 1. Automatic timing boot This feature needs to be set in the BIOS, and your motherboard's advanced power management settings must support this feature, but now most of the motherboard support, rest assured to use it. step one: Start the system press DEL, enter the BIOS, and then select the "POWER MANAGEMENT FEATURES" (Power management settings), enter in the power window to find "RESTORE ON AC / POWER LOSS "item, press Enter, and then set the value to" POWER ON "with the arrow keys. Step two: Select "RESUME ON RTC ALARM" and press Enter, then use the arrow keys to set its value to "ENABLE" Step three: Select "RTC ALARM DATE" press Enter, and then set its value to "EVERYDAY", that every day the same operation, in accordance with the same method, respectively, "RTC ALARM HOURS" "RTC ALARM MINUTE" "RTM ALARM SECOND "Set to" 07 "" 15 "" 00 ", which means the boot time for the morning" 7:15:00 ", all set up, press F10, save and restart. (Due to the different motherboard BIOS is not the same, some motherboard settings may be a little bit different from the above, but just remember to find in the power management "WAKE UP" words on the line, because this is set the timing boot option)
- Q: For example, I use the IGBT circuit switch, using the same gate resistance and drive circuit. Then use it to make a normal working current only 1A off the external circuit off time And let a current up to 100A of the external circuit completely off the turn-off time, Will there be a big difference between the two times? Or that depends entirely on the drive part of the control of the gate G, CE voltage at both ends of the voltage is not much relationship?
- Switch with IGBT, the switch time with the load current size does not matter. IGBT can not control the size of the current, IGBT is only a switching device, when connected to the circuit, used to control the circuit off time. IGBT and inductance together to achieve the control of the current. Take the voltage source as an example, only consider the main circuit, voltage source, IGBT, inductance, load series, when the IGBT is turned off, the power and inductance disconnected from the inductor to the load power supply, the inductor current can not be changed, but will decline. When the IGBT is turned on, the power supply and inductance connected to the power supply to the inductor and load power supply, the inductor current can not be mutated, but will rise. The current in the inductor and the rise of how much, by the IGBT turn off and open the time to determine, that is the IGBT turn on and off the law determines the law of the current changes in the inductor, also said that the realization of the current control.
- Q: Microcomputer tb-12 timer switch how to adjust the time
- The timing setting procedure is as follows: Press the "timer" button, you can enter the first set of each set of interface: "1 open 00:00 C1" → "1 off 00:00 C1" ... ... can be "5 off 00:00 C1" Time "key to enter the second set interface:" 1 open 00:00 C2 "→ ..." 5 off 00:00 C2 ". And then press it again to the clock interface. The The The Repeated loop In the above settings, the interface can be "week, hour, minute" key, adjust the set week, hours, minutes, where the interface suffix "C1
- Q: Notebook switch machine time will be reset how to do
- Reason and solution: 1, the time is not set to synchronize with the Internet time server; Method: click on the computer task bar on the time, select "change the date and time settings", as shown; 2, in the settings inside select "Internet time" in the following select "change settings" and then "synchronization with the Internet time server" before the box tick, as shown; ?3, through the computer service to set the time to update; ???????Right click on "My Computer", select "Manage", select "Services and Applications", double-click "Service", and then in the service list to find "Windows Time", right-click through the "Properties" computer synchronization Service set to automatic, as shown; 4: Possible reason is the virus in the computer; ?????Solution: Some viruses can also lead to the system can not automatically update, open your anti-virus software on the computer for a comprehensive anti-virus bar; 5: the computer motherboard battery is dead or damaged; ???????Computer motherboard battery power or damage caused your computer motherboard clock can not run, in your computer power failure can not automatically update, then you just go to a motherboard battery on it;
- Q: Home line air switch closed after a period of time on the trip What is the reason?
- 3 in the air switch below a part of the line where the environment is too wet line insulation damage caused by leakage earth fault. 4 in the air switch below the line there are short-circuit points, such as a section of the line insulation damage to the aging of the insulation performance caused by a short line between the zero line and the line of fire, or an electrical failure If this is the case you can disconnect all the electrical Power and then send the power if you can send all the electrical appliances can be connected to a power supply to see if there will be a trip if the air switch trip to find the reason.
- Q: Such as the intake valve: the top dead center before -3 degrees open, to 37 degrees, then it should be closed from 37 or 38 degrees, why is it after the bottom point of 71 degrees?
- According to this theory, the automobile industry to produce the medium-term, basically into the exhaust valve opening time ahead of time, closing time delay, so that the top deadline and the bottom deadline + -4 ° range, the intake valve and exhaust Door at the same time open the phenomenon, called the valve phase.
