Problems solved by technology

However, due to the influence of the high-voltage line, there is a large electric field around it. When the staff enters the high-voltage dangerous area, they cannot perceive the potential danger of the electric field, which will affect the staff's body, such as headache, fatigue, insomnia; even cause more serious injury
[0003] There is only one preset field strength value in the current alarm method, because the strength of the field s...

Abstract

The invention discloses a method for electric field alarming. The method comprises: the current field intensity is detected and a field intensity detection value corresponding to a field intensity signal is obtained; whether the current field intensity detection value is larger than a first preset field intensity value is determined; if so, a first alarm signal is outputted; when the first alarm signal is received, alarm prompting is carried out; whether the current field intensity detection value is larger than a second preset field intensity value is determined; if so, a second alarm signal is outputted; and when the second alarm signal is received, alarm prompting is carried out. The first preset field intensity value is smaller than the second preset field intensity value. Therefore, segmented prompting is realized by outputting alarm signals twice. Compared with the existing method of sending out one piece of alarm prompting information by setting one preset field intensity value, the provide method enables the humanization effect to be improved and the functions to be diversified. In addition, the invention also discloses an apparatus for electric field alarming.

Example Embodiment

[0040] Example one
[0041] figure 1 It is a flowchart of a method for electric field alarm provided by the present invention. Such as figure 1 As shown, the methods for electric field alarm include:
[0042] S10: Detect the current field strength and obtain the field strength detection value corresponding to the field strength signal;
[0043] S11: Determine whether the current field strength detection value is greater than the first field strength preset value;
[0044] S12: Output the first alarm signal in the case that the current field strength detection value is greater than the first field strength preset value;
[0045] S13: Send an alarm prompt when receiving the first alarm signal;
[0046] S14: Determine whether the current field strength detection value is greater than the second field strength preset value;
[0047] S15: output a second alarm signal when the current field strength detection value is greater than the second field strength preset value;
[0048] S16: Send an alarm prompt when receiving the second alarm signal;
[0049] Wherein, the first preset value of field strength is smaller than the second preset value of field strength.
[0050] Such as figure 1 As shown, the first step is to detect the current field strength and obtain the field strength detection value corresponding to the field strength signal, and determine whether the obtained field strength detection value is greater than the first field strength preset value, if it is, it indicates that the first alarm signal is reached The limit. If not, it means that the current field strength is still relatively small and will not have an adverse effect on the human body. Therefore, there is no need to prompt. When the current field strength detection value is greater than the first field strength preset value, the first alarm signal is output, and then a corresponding alarm prompt is issued according to the first alarm signal. It can be understood that the field strength is changing in real time, for example, the field strength is gradually increasing, so it is necessary to continue to determine whether the current field strength detection value is greater than the second field strength detection value. Therefore, in specific implementation, the duration of the alarm prompt corresponding to the first alarm signal can be as short as possible, such as 3 seconds, so as not to affect the alarm prompt corresponding to the second alarm signal. In other words, step S14 can be executed after the alarm prompt corresponding to the first alarm signal ends.
[0051] Then continue to determine whether the current field strength detection value is greater than the second field strength preset value, and if it is, it indicates that the second alarm signal limit has been reached. If not, it means that the current field strength is still between the first preset value of field strength and the second preset value of field strength, and will not have a significant impact on the human body. Therefore, there is no need to prompt for the time being. When the current field strength detection value is greater than the second field strength preset value, the second alarm signal is output, and then the corresponding alarm prompt is issued according to the second alarm signal.
[0052] In a specific implementation, the first preset value of field strength and the second preset value of field strength can be regarded as set. Less than the preset value of the first field strength indicates no harm to the human body, between the preset value of the first field strength and the second preset value of the field strength indicates harm to the human body, but the degree of harm is small; greater than the second field strength The preset value indicates a greater degree of harm to the human body. Therefore, the alarm prompt corresponding to the first alarm signal can be used as the first stage of alarm to inform that there are high-voltage charged objects around; the alarm prompt corresponding to the second alarm signal warns that the safe working distance is approaching and increases vigilance.
[0053] In a specific implementation, the alarm prompt corresponding to the first alarm signal is different from the alarm prompt corresponding to the second alarm signal, which can facilitate the staff to know the surrounding environment corresponding to the current alarm prompt.
[0054] In the method for electric field alarm provided in this embodiment, by setting the first preset value of field strength and the second preset value of field strength, the first field strength detection value is greater than the first field strength preset value. An alarm signal is used to issue an alarm prompt; when the current field strength value is greater than the second field strength preset value, a second alarm signal is output, and an alarm prompt is issued again. It can be seen that this method realizes segmented prompts by outputting two alarm signals, which is more humane than setting a preset field strength value to send out an alarm prompt.
[0055] The preset value of the first field strength is 100V/m, and the preset value of the second field strength is 1000V/m.
[0056] It can be understood that the first preset value of field strength and the second preset value of field strength can be set according to actual conditions. The setting of the preset value of the first field strength and the preset value of the second field strength can be carried out by a method of simulation experiment or by a method of experimentation, which will not be repeated in the present invention.
[0057] Among them, it also includes displaying the current field strength detection value.
[0058] Since on the basis of the foregoing embodiment, the staff can only obtain two alarm prompts, and cannot know the current field strength value, this embodiment further informs the staff by displaying the current field strength detection value.
[0059] The alarm module includes at least one of a flashlight, a vibration module, and a buzzer.
[0060] On the basis of the foregoing embodiment, the alarm module can be any combination of a flashlight, a buzzer, and a vibration module. It can be understood that when the flashlight is working, it can be in a constant light state or a flashing state; the vibration module can vibrate continuously or intermittently; the buzzer can be in a long beep state or an intermittent beep state.
[0061] In order to facilitate the staff to know whether the current alarm notification corresponds to the first alarm signal or the second alarm signal, in specific implementation, the alarm notification corresponding to the first alarm signal can be distinguished from the alarm notification corresponding to the second alarm signal.
