Description

Technical Field

[0001] The present invention relates to the technical field of lightning early warning, in particular to a device and method for shutting down city power and simultaneously starting UPS power supply when lightning is approaching. Background Art

[0002] Lightning monitoring and early warning refers to the use of observation data such as lightning location, radar, satellite, atmospheric electric field and sounding, through multi-data fusion application, statistical analysis, near-field extrapolation and numerical forecasting and other technical means to identify, track and forecast and warn areas where lightning may occur or has occurred. Based on the lightning monitoring and early warning system, the Guangdong Provincial Meteorological Bureau has carried out real-time monitoring of lightning activities and lightning proximity graded early warning for key lightning-sensitive places such as Guangzhou Tower and Guangzhou Petrochemical, effectively preventing and reducing the threat of lightning.

[0003] However, the existing lightning warning can provide early warning, but large computer rooms still have the following defects when the power is off: 1. Although the existing lightning warning device can provide early warning of lightning, it cannot automatically shut down the power supply of the computer room in time.

Each electric field meter shared on a computer must have a unique port number so that an alarm can be issued under the above operations, so that it can be disconnected and closed manually and efficiently.

[0012] The present invention has the following advantages: 1. With the present invention, as long as the potential is different, the electric field will change. If the electric field becomes high enough, you can feel the ends of your hair. The electric field is the reason why your hair is attracted to the charged comb or charged balloon.

[0013] The unit of electric field is volts per meter (1 meter = 3.28 feet), and the electric field accompanying a thunderstorm is usually measured in thousands of volts per meter, often abbreviated as kV / m. Lightning can be detected as a sudden change in the electric field.

[0014] The electric charges in a thundercloud also create an electric field. This magnetic field can be measured on the ground.

[0015] To obtain accurate electric field readings, the field electric field meter needs to be mounted flush with the ground. However, mounting the field electric field meter flush with the ground is not practical because water, dirt, insects, etc. will gather around the sensing electrode and contaminate the electrode insulator.

[0016] E-field meters mounted above ground level will intensify the electric field, resulting in higher than correct readings. Sensitivity plugs are provided to reduce the sensitivity of the E-field meter and compensate for higher E-field meter readings.

[0017] The electric field meter senses a range of electric fields by repeatedly exposing and shielding the sensing electrode.

[0018] The electric field meter uses a mechanical chopper to alternately shield and expose multiple sensing plates to the electric field. When the sensing plates are exposed to the electric field, charge is attracted from the ground to the plates through the sense resistor. When the sensing plates are shielded, the charge flows from the sense resistor to the ground again. This moving charge forms a current, and the voltage across the sense resistor can be measured. The magnitude of the voltage is proportional to the electric field applied to the sensing plates.

[0019] The charge flowing into and out of the sensing electrode will generate a voltage across the sensing resistor. This voltage is amplified and fed out of phase to the analog switch.

[0020] Before installing the sensor, connect and test it in the ground. Install the software on your computer and connect the device to display the configuration. The field electric field meter should respond to a charged object approaching. Most plastic items can be charged by rubbing against clothing. BRIEF DESCRIPTION OF THE DRAWINGS

S14-7-1, Monitoring port The computer listens to the port for incoming connections. Each electric field meter shared on a computer must have a unique port number so that an alarm can be issued under the above operations, so that it can be disconnected and closed manually and efficiently.

[0029] Without the sensitivity connector installed, the relative sensitivity of the field meter is 1.0. The sensitivity plug installed on the field meter reduces the sensitivity of the field meter to compensate for the enhanced electric field. The lower the number, the lower the sensitivity. For example, a 0.25x plug reduces the sensitivity to 1 / 4 of normal.

[0030] Most electric field meter installations do not require accurate calculation of the correction coefficient. On a sunny day, just select the appropriate sensitivity so that the value it produces is closest to the normal value. The electric field on a sunny day is about 0.1 kV / m. If the electric field meter reading exceeds 20 kV / m (the limit of the electric field meter) during a thunderstorm, replace the sensitivity plug with a low-sensitivity plug when it is sunny. The software is the existing technology.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
