Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is further described:
A kind of high voltage induction attention device, as shown in Figure 1, comprise power module, MCU module, voltage sensor, signal conditioning circuit, warning voltage selection shelves and alarm module, wherein power module is connected with MCU module, signal conditioning circuit and alarm module for above-mentioned module for power supply, voltage sensor, signal conditioning circuit and MCU module are connected successively and realize voltage detecting function, and MCU module is also provided with an output terminal and is connected with alarm module and realizes warning function.MCU module is also provided with an input end and selects shelves to be connected for arranging different warning magnitudes of voltage from warning voltage, can arrange warning magnitude of voltage flexibly according to different occasions.
In the present embodiment, what voltage sensor adopted is capacitive battery pressure sensor, and power module employing 4.5V button cell as working power is; Described signal conditioning circuit is connected and composed successively by discharge circuit, filtering circuit, detecting circuit, and described MCU module is connected and composed by single-chip microcomputer and peripheral circuit thereof, and described alarm module adopts sound and light alarm module.Capacitive battery pressure sensor is as sensing element induction voltage signal around, signal conditioning circuit is nursed one's health the voltage signal that voltage sensor is responded to and is then sent into MCU module, that is: discharge circuit carries out amplification process to voltage signal, filtering circuit carries out filtering process, detecting circuit is sent in MCU module after carrying out detection process, measuring voltage value is calculated by the signal of MCU module to input, the warning magnitude of voltage that measuring voltage value and warning voltage gear are selected compares by MCU module, when the magnitude of voltage that MCU module is measured is greater than the warning magnitude of voltage of warning voltage gear selection, MCU module sends alarm command to alarm module, sound and light alarm signal is sent by alarm module, realize the warning function of high voltage induction attention device.The operating voltage range of this high voltage induction attention device is 0-500kV; Early warning distance: 10kV (0.7 meter), 35kV (1 meter), 110kV (1.5 meters), 220kV (3 meters), 330kV (4 meters), 500kV (5 meters).
This high voltage induction attention device can be arranged on insulating boot, insulating glove or other need the place of alarm, when the magnitude of voltage that it detects is greater than warning magnitude of voltage, sounded by audible-visual annunciator and report to the police and light flash warning, make operations staff remain at work in safe distance, thus reduce the generation of power grid security accident.
It is emphasized that; embodiment described in the utility model is illustrative; instead of it is determinate; therefore the utility model comprises the embodiment be not limited to described in embodiment; every other embodiments drawn according to the technical solution of the utility model by those skilled in the art, belong to the scope of the utility model protection equally.
