Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

As shown in Figure 1, the utility model provides an automatic alarm device, comprising:

An electric field intensity sensing module 100 for measuring the surrounding electric field intensity;

There is an electric field near the charged wire A, the closer the distance to the charged wire A is, the greater the electric field intensity is, and the farther the distance is, the smaller the electric field intensity is, so the magnitude of the electric field intensity can represent the distance between the charged wire A and the electric field intensity sensor in this device Continuously collect the surrounding electric field strength to provide evidence for the distance between the operator and the live wire A.

A first microcontroller 200 that is connected to the electric field strength sensing module 100 and sends a first alarm instruction when the electric field strength reaches a preset value;

The first micro-controller 200 judges according to the electric field strength. When the electric field strength is greater than the preset value, it is considered that the distance between the operator and the live wire A has reached a safe distance, so an alarm command is sent to control the alarm module to give an alarm to remind Operators can no longer approach the live wire A to prevent electric shock. When the electric field intensity is lower than the preset value, the first micro-controller 200 does not give an alarm, so as not to disturb the attention of the workers.

A setting module 300 that is connected to the first microcontroller 200 and sets the preset value;

In the power industry, the specified distance between the operator and the live conductor A is clearly stipulated. Taking the 35kV live conductor A as an example, the specified distance between the outermost body of the operator and the live conductor A is at least 1.2m, which can be The magnitude of the electric field intensity at 1.2m away from the live wire A is used as the preset value when the operator is working at the 35kV live wire A.

The automatic alarm device provided by the utility model is not installed on the head and limbs, but is installed on the abdomen position on the front of the body or the waist position on the back of the body, so that the head and limbs can move flexibly when the worker is working, but considering the upper limbs and The lower limbs need to have room for movement, so the electric field strength corresponding to the specified distance in the industry specification cannot be directly set to the preset value in this device, but the movement distance of the upper and lower limbs needs to be increased on the basis of the specified distance, and the movement distance will be increased. The corresponding electric field strength after the distance is used as the preset value. Taking 35kV as an example, the safety distance in the industry standard is 1.2m. Considering the movement distance of the upper and lower limbs, the electric field intensity corresponding to 1.7m can be used as the preset value.

The first alarm module 400 connected to the first microcontroller 200 receives the first alarm instruction and sends an alarm.

The utility model provides an automatic alarm device. When a worker is working, the electric field intensity sensor 100 collects the electric field intensity around the worker in real time, and the first micro-controller 200 is preset with a preset value corresponding to the safety distance. After the controller 200 receives the electric field strength, it compares the electric field strength with the preset value, and when the electric field strength is greater than the preset value, it is considered that the distance between the worker and the charged conductor A reaches a safe distance, and an alarm command is issued at this time, The first alarm module is controlled to give an alarm, so as to remind the workers not to approach the live wire A any more, so as to achieve the purpose of protecting the personal safety of the workers. The internal execution method in the first microcontroller 200 is a function that can be realized by the modules carried in the microcontroller itself, which should be understood as the prior art.

In the utility model, the electric field strength collected by the electric field strength sensor 100 represents the distance between the worker and the charged wire A, instead of the distance measured by the traditional guardian, and the first micro-controller 200 judges whether the electric field strength and the preset value exceed the distance. The safety distance replaces the traditional guardian's visual distance and judges whether the distance exceeds the safety distance through perception. Therefore, compared with the prior art, the automatic device provided by the utility model can accurately determine the distance between the worker and the live wire A, and can Accurately determine whether the distance between the worker and the live wire A is greater than the safety distance, and timely alarm when it is greater than the safety distance, so as to achieve the purpose of accurately identifying the distance, accurately judging the distance and timely reminding.

In order to achieve the purpose of better protecting workers, the setting module in the utility model provides two preset values, the first preset value for the initial alarm and the second preset value for the second alarm, when the electric field intensity reaches the first When the first preset value is reached, the initial alarm is issued to remind the worker that the distance between the live wire A and the live wire A is relatively short. The secondary alarm is used to warn the user not to be close to the live wire A, so as to cause an accident.

In the utility model, the distance between the operator and the charged wire A is reminded through two alarms. Of course, multiple reminders can also be set, but too many reminders will also cause the operator to be distracted. Therefore, the preferred in the utility model is Alert the staff twice.

Because in the prior art, two live wires A of 35kV and 110kV are generally operated, and the preset values of different live wires A are different, so different preset values are set for 35kV and 110kV respectively in the utility model. As shown in Figure 2, the first setting module 301 includes a first 35kV setting module 3011 and a first 110kV setting module 3012; the second setting module 302 includes a second 35kV setting module 3021 and a second 110kV setting module 3022.

Among them, the first 35kV setting module 3011 is used to set the first preset value when the live wire A is 35kV and the first alarm is the first time, and the first 110kV setting module 3012 is used to set the first preset value when the live wire A is 110kV. Set the value, the second 35kV setting module 3021 is used to set the second preset value when the live wire A is 35kV and alarms again, and the second 110kV setting module 3022 is used to set the second preset value when the live wire A is 110kV and alarms again. set value.

In order to distinguish between 35kV and 110kV alarms respectively, the switch 303 is used to determine the current use preset value of the first microcontroller 200, as shown in Figure 2, when the switch is up, the setting module provides the first microcontroller 200 with an alarm. The preset value for working on the 35kV live wire A, when the switch is down, the setting module provides the first microcontroller 200 with a preset value for working on the 110kV live wire A. That is, the switch is simultaneously connected to the first 35kV setting module and the second 35kV setting module, or the first 110kV setting module and the second 110kV setting module. When the user is in use, the direction of the changeover switch is directly determined according to the voltage of the current working live conductor A.

Preferably, in specific use, the safety distance set by the first 35kV setting module 3011 corresponding to the first preset value is 1.9m; the safety distance set by the second 35kV setting module 3021 and the second preset value The safe distance corresponding to the value is 1.7m; the safe distance set by the first 110kV setting module 3012 and corresponding to the first preset value is 2.4m; the set by the second 110kV setting module 3022 and the second The safety distance corresponding to the preset value is 2.2m.
