Nowadays, all walks of life need electricity. The safe operation of power infrastructure is the premise of national economic development. It is vital to ensure the safe operation of power equipment and lines. It is also important for the maintenance and maintenance of power equipment and lines.
Due to the long-term exposure of power lines and equipment to nature, it not only suffers from normal mechanical loads and electrical loads, but is also often attacked by external forces such as lightning strikes, strong winds, and floods. A variety of factors will cause damage to various components on the line and equipment. If not discovered and eliminated in time, it may develop into various faults, posing a threat to the safety and stability of the power system. Therefore, the equipment operation support department of the power company will invest a large amount of manpower, material resources and financial resources to ensure the safe transportation of electric energy, so that these power equipment and lines can maintain normal working conditions.
At present, the inspection of power equipment adopts a relatively traditional recording method such as personnel sign-on or leadership spot check, which has poor reliability and low efficiency. It is not easy for managers to understand the working status of the inspectors, and lacks scientific and normative management of personnel. The new power equipment handheld terminal inspection system, for the actual needs and characteristics of the inspection work, has the functions of route arrangement, data recording, work status supervision, data summary report, etc., and can provide high-efficiency cost management means.
The application of the GPS module on the handheld terminal device: positioning navigation, the inspection personnel to track and locate, check the on-the-job and work status of the inspection personnel at any time, and improve the safety of the staff.
GPS module MAX-6Q
The U-blox MAX-6 GPS module series in Switzerland achieves the superior performance of the U-blox6 positioning engine in MAX's ultra-small package. U-blox 6 is designed for low power consumption and low cost, 9.7X10.1X2.5mm super Small package, very suitable for mobile handheld devices.
Omnidirectional antenna SL1206
The SL1206 GPS active antenna based on Sarantel's patented GeoHelix-P2 features a high performance, high gain, low noise amplifier and SAW filter. Designed for applications that require higher gain and require active signals, it effectively attenuates nearly 30dB of GSM and ISM signals.
Wireless communication module application on handheld terminal equipment: GPRS transmission, call function, patrol personnel to transmit recorded data in time
Wireless communication module SARA-G350
The main features of u-blox's GSM/GPRS wireless communication module SARA-G3 series are extremely low power consumption and small LGA package. The low power standby current is less than 0.90mA.
SMA means surface mount assembly. It is a new generation of electronic assembly technology, which compresses traditional electronic components into a device with a volume of only a few tenths.
Surface mounting is not a new concept, it is derived from earlier processes, such as flat mounting and mixed mounting.
For the assembly of electronic circuits, a point-to-point wiring method was initially adopted, and there was no substrate at all. The packaging of the first semiconductor device uses radial pins, which are inserted into the through holes of the monolithic circuit boards that have been used for the packaging of resistors and capacitors. Active components have been widely used in the past ten years.
