Measured value.
S14：Wireless communication module sends field strength detected value to mobile terminal.
S15：Mobile terminal compares field strength detected value and the first field strength preset value, and is more than the first field strength in field strength detected value
During preset value, the first alarm is sent.
The measurement of the field strength of electric field is to analyze a kind of conventional method of surrounding charged object.Held by automatic mobile device
Electric field detector is carried to automatically move on the track of setting.Because electric field detector can detect the field strength letter of surrounding electric field
Number.Locating module obtains the distance of mobile terminal and automatic mobile device, and is sent through distance signal to automatic mobile device
Processing module.Due to field intensity signal can with becoming big with the distance of electrical body or diminish, and electric field detector be arranged on from
In dynamic mobile device, so the field intensity signal detected is field strength corresponding to environment where automatic mobile device, therefore, it is necessary to
Locating module obtains the distance of mobile terminal, and then processing module is according to where field intensity value is changed to mobile terminal by distance signal
Field strength detected value corresponding to environment.The field strength detected value is exactly the true field intensity signal of the environment where mobile terminal.Channel radio
Letter module sends the field strength detected value that processing module converts to mobile terminal.Mobile terminal compares field strength detected value and first
The size of strong preset value, and when field strength detected value is more than the first field strength preset value, send the first alarm.
It should be noted that automatic mobile device can be unmanned machine or other devices that can be automatically moved；Electricity
Field detection means can be sensor of the strong signal of detecting field etc..The acquisition as long as mobile terminal can communicate with wireless communication module

In order to cause staff to obtain the field intensity value of local environment in time, therefore mobile terminal is additionally operable to show field
Strong detected value.Staff can watch the field strength detected value that wireless communication module is sent by the display screen of mobile terminal.
Wherein, mobile terminal also compares field strength detected value and the second field strength preset value, and is more than second in field strength detected value
During field strength preset value, the second alarm is sent；
Wherein, the first field strength preset value is less than the second field strength preset value.
Represent not injure human body less than the first field strength preset value, preset between the first field strength preset value and the second field strength
Represent there is injury to human body between value, but extent of injury is smaller；Represented more than the second field strength preset value to human injury's degree
It is larger.Therefore, when alarm can corresponding to the first alarm signal plays the alarm of first stage, inform around have high pressure
Electrical body；Alarm is just alerted already close to safety work distance corresponding to second alarm signal, is enhanced your vigilance.
In specific implementation, the alarm corresponding with the second alarm signal of alarm corresponding to the first alarm signal is not
Together, so staff can be facilitated to know surrounding environment corresponding to current alarm.
It should be noted that the first default field intensity value and the second default field intensity value are pre-set, can be according to reality
Situation is set.First default field intensity value and the second default field intensity value are a critical values, that is, have exceeded this value meeting of indicating that
Certain harm is caused to health.For example, the first default field intensity value can be set as 100V/m, the second default field intensity value is
1000V/m。
