Problems solved by technology
[0003] However, the existing products can only detect the electric field to make an early warning, and only rely on a single electric field threshold, the probability of false alarms is high, and at the same time, it cannot indicate the direction of the electric field source. Guide staff to exit the dangerous range, increasing safety hazards, and existing products are limited to sound and light alarms, no data storage

Embodiment
[0032] see figure 1 , figure 1 It is a schematic flowchart of a safety warning method for a near-electricity warning safety helmet for judging the location of a field source in an electrified field disclosed in an embodiment of the present invention. like figure 1 As shown, it includes the following steps:
[0033] Step 1: Acquire the collected field strength values of five electric field measurement sensors, where the collected field strength value of the electric field measurement sensor i is denoted as E i , i=1~5.
[0034] In a preferred embodiment of the present invention, the near-electric warning safety helmet used for judging the location of the field source of the charged field includes a safety helmet body, and 5 electric field measurement sensors are installed on the safety helmet body, and the 5 electric field The measuring sensors are recorded as No. 1 electric field measuring sensor, No. 2 electric field measuring sensor, No. 3 electric field measuring sens...

The embodiment of the invention relates to the technical field of near-electricity early warning, and discloses a near-electricity early-warning safety helmet for judging the position of a field source of an electrified field and an early-warning method of the near-electricity early-warning safety helmet. The safety helmet comprises a safety helmet body, five electric field measuring sensors are installed on the safety helmet body, and the five electric field measuring sensors are marked as the first electric field measuring sensor to the fifth electric field measuring sensor respectively; wherein the first electric field measurement sensor, the second electric field measurement sensor, the third electric field measurement sensor and the fourth electric field measurement sensor are located in the same plane, and a connecting line between the first electric field measurement sensor and the third electric field measurement sensor is perpendicular to a connecting line between the second electric field measurement sensor and the fourth electric field measurement sensor; the fifth electric field measurement sensor is located above the center of the first to fourth electric field measurement sensors. By implementing the embodiment of the invention, the staff can be guided to evacuate from the direction in which the electric field is weakened, and is prevented from entering a more dangerous area by mistake.
Description
technical field [0001] The invention relates to the technical field of near-electricity early warning, in particular to a near-electricity early warning safety helmet and an early warning method for judging the position of a field source in a charged field. Background technique [0002] At present, electric field strength early warning sensing devices, near electric alarm helmets, near electric induction sound and light alarm helmets, etc. are used for early warning of near electric field strength, involving electric field sensors, filters, signal processing units, sound and light alarm devices, etc., which can Predict whether the nearby electric field is dangerous and warn users to avoid danger through sound and light alarm. [0003] However, the existing products can only detect the electric field to make an early warning, and only rely on a single electric field threshold, the probability of false alarms is high, and at the same time, it cannot indicate the direction of t...
