Description

An automatic rescue device for field operations in distress

Technical field

The invention relates to the field of safety equipment, and in particular to an automatic calling device for help in field operation distress.

Background technique

Electric power repair and maintenance is one of the necessary means to ensure the normal operation of the power grid. For this reason, a large number of repair and maintenance personnel are rushing around the land of the motherland, using their hard efforts to maintain the normal operation of the power grid. The repair and maintenance work of the power grid requires climbing up and down, which is inherently dangerous. This work is even more dangerous especially in a field operation environment.

Electrical power maintenance is generally carried out as a team, and each team member looks after each other. Accidents rarely occur, but it is inevitable to face the situation of working alone in the field. When a person is in danger in the wild, they can only rely on self-rescue. However, if the injury is serious and unable to move, most people can only wait for rescue to arrive.

But it must be taken into account that this wait is quite long. Only when the rest of the staff find out that he is missing will they search, and without effective positioning information, the search process will be very long. Persons in distress are likely to miss the opportunity for rescue.

The invention can automatically send out an alarm signal according to the collected signal, thereby improving the safety of field operations. Maintenance personnel will always use their hands during the work process, which means that the present invention is always in a vibrating state; most people need to walk when rushing to the work site in a wild environment, and people's hands are also in a shaking state when walking, and the present invention is also in a shaking state. In a shaking state; even if you ride a vehicle, the road conditions in the wild are very poor, the vehicle bumps, and people shake with the vehicle. The present invention is also in a shaking state. This means that in the wild environment, the invention is basically in a shaking state, and the vibration sensor in the housing can detect the vibration signal at all times. When the vibration sensor cannot detect the vibration signal, it means that the worker is not moving at this time and is in a stationary state. . At this time, the clock starts to work. When its feedback time reaches a preset value, it means that the worker has been stationary in the field for a very long time, which is very abnormal. At this time, the buzzer and wireless communication module start working at the same time. The buzzer can send out a warning signal to other people nearby, reminding everyone to come and check; the wireless communication module can send a signal to the host computer, and the monitoring personnel can get the warning information through the host computer. , can quickly discharge rescuers or notify nearby people to go to the rescue, shorten the rescue time, and improve the survival rate of rescuers.

The invention is also provided with an emergency alarm part. When a person in distress finds that the automatic alarm part cannot work, the emergency alarm part can be activated to send a warning signal. The specific working process is: press the sliding column, and the sliding column cuts off the wires as it moves downward. The control chip then drives the buzzer and wireless communication module to start working.

Detailed ways

The present invention will be further described below in conjunction with Figures 1-5.

The present invention adopts the following technical solutions:

An automatic emergency calling device for field operations, including a shell 1, a fastening strap 2 provided on the shell 1, a control chip 3 installed in the shell 1, a vibration sensor 4 connected to the control chip 3, and a fixed strap 2 mounted on the shell 1 The buzzer 5 on the outer surface, the wireless communication module 6 connected to the control chip 3 and the power module 7 connected to the control chip 3;

The vibration sensor 4 and the wireless communication module 6 are both installed inside the housing 1 .

As a further solution: the top of the housing 1 is an open end; a screw cap 7 is provided on the top of the housing 1; the screw cap 7 is threadedly connected to the housing 1.

As a further solution: an emergency alarm part is also included; the emergency alarm part includes a sealing shell 81 fixedly installed on the outer wall of the housing 1, a wire 82 provided in the sealing shell 81, and a sliding column slidingly connected to the sealing shell 81. 83. The limiting ring 84 fixed on the sliding column 83 and the spring 85 sleeved on the sliding column 83;

The sealing shell 81 is made of insulating material;

The wire 82 is located in the groove on the bottom surface of the sealing shell 81; both ends of the wire 82 are connected to the control chip 3;

One end of the spring 85 is in contact with the sliding column 83 , and the other end is in contact with the bottom surface of the sealing shell 81 .

As a further solution: a clock 10 connected to the control chip 3 is also included.

During the repair and maintenance process, the staff places the invention on the wrist and wears it on the wrist by tightening the strap 2 in the same way as wearing a watch. If necessary, you can push it back and into the sleeves of your overalls.

When a staff member is in danger and unable to move, he or she will lie on the ground unable to move or be in an unconscious static state. The vibration sensor 4 cannot sense the vibration and cannot send a signal to the control chip 3. The control chip 3 sends a start signal to the buzzer 5 and the wireless communication module 6. The buzzer 5 starts to work and sounds an alarm, and the wireless communication module 6 sends a signal to the host computer to report the worker's distress information.

However, considering that the staff may be in a stationary state for a short time, if the control chip 3 cannot receive the signal sent by the vibration sensor 4, it will send an alarm signal, and false alarms may easily occur, so a clock 10 is specially added. When the control chip 3 cannot obtain the signal sent by the vibration sensor 4, the clock 10 starts timing. When the timing time reaches the set time, the control chip 3 sends a working signal to the buzzer 5 and the wireless communication module 6, and they start to work. , the buzzer 5 sends an alarm signal to remind the surrounding staff to come and check, and the wireless communication module 6 sends an alarm signal to the host computer; but during the timing of the clock 10, the control chip 3 regains the signal sent by the vibration sensor 4, It means that the staff is not in danger and the control chip 3 does not send working signals to the buzzer 5 and wireless communication module 6 .

At the same time, considering that the shock sensor 4 may be accidentally damaged when the staff is in distress, an emergency alarm part is especially added. When the staff in distress finds that the buzzer 5 is not working or needs to send an alarm signal immediately, press the sealing shell 81 The sliding column 83 moves downward. There is a blade on one end of the sliding column 83 located in the sealing case 81, which can cut into the sealing case 81 to cut off the wire 82. After the wire 82 is cut off, the control chip 3 gets a signal and sends a start signal to the buzzer 5 and the wireless communication module 6. Both start working.

The spring 85, the limiting ring 84 and the grooves in the sealing shell 81 are all designed to avoid misoperation. When the staff touches the sliding column 83 unconsciously, they will generally leave quickly. At this time, the spring 85 will push the sliding column 83 back to its original position. The function of the limiting ring 84 is to prevent the sliding column 83 from being separated from the sealing shell 81 . The electric wire 82 located in the groove can prevent the sliding rod 83 from cutting off the sealing shell 81 after contacting it.
