Problems solved by technology

[0002] In the field of substation construction, there are limited space operations such as wells, boxes, cabinets, deep pits, tunnels, and cable interlayers. Most of the operating environments are closed or partially closed, with narrow entrances and exits, limited space, and poor natural ventilation. The accumulation of toxic and harmful, flammable and explosive substances or insufficient oxygen content threatens the health and safety of workers
[0003] In the conventional limited space operation, during the operation process, there is an operation guardian to judge the physical condition of the operator through the call of the walkie-talkie. Aspects can lead to lower worker productivity, which increases normal working hours and increases operational risk

Embodiment 1

[0035] A safety monitoring device for workers in a limited space, including a wearable bracelet 10 and a mobile terminal 40, the wearable bracelet 10 includes a working part and a wearing part, the working part includes a processor module 30 and an alarm module 20, and the processor module 30 includes an acceleration sensor device 31, the acceleration sensor is composed of a ball 311 and a piezoelectric sheet 312, the piezoelectric sheet 312 is concave, and the top surface of the concave space of the piezoelectric sheet 312 is closed by the shell 11 of the working part of the wearing bracelet 10, and the ball 311 is pressed The electric sheet 312 and the working part shell 11 roll freely in the concave space formed by the piezoelectric sheet 11, and no signal is generated by the piezoelectric sheet 11. When the wristband 10 is shifted from the original space position to produce instantaneous acceleration or deceleration, the ball 311 changes due to the force. When it collides w...

Embodiment 2

[0042] A certain construction includes operations in a limited space. The safety monitoring device for operators in a limited space is used to monitor the safety of operators, and the operators wear wristbands 10 for operations. During normal operation, because the operator's hand will show short-term regular movements and long-term irregular movements, when wearing the acceleration sensor 31 in the wristband 10, the ball 311 will continue to roll in the bracelet due to the movement of the operator, colliding with the piezoelectric Chip 312 emits electrical signals. The electrical signal is processed by the signal processor 32 into the working signal A of the action signal and sent by the signal transmitter 33. The mobile terminal 40 receives the working signal A, and the signal module 41 judges that the working signal A indicates that the physical condition of the operator is normal. 431 is displayed normally.

[0043] Every half an hour, the guardian sends the query signal ...

Embodiment 3

[0045] A certain construction includes operations in a limited space. The safety monitoring system for operators in a limited space is used to monitor the safety of operators, and the operators wear wristbands 10 for operations. When the guardian sends the inquiry signal B to the wearable bracelet 10 through the mobile terminal 40, but does not get the feedback of the health signal C within the set time 15S, the signal module 41 will send a dangerous signal D for processing the signal to the signal display screen 431 and the alarm 42. The signal display screen 431 displays a danger signal and the alarm 42 starts to alarm, reminding the guardians that the workers may have suffocation or other dangers.

[0046] At this time, the signal receiver 34 will not stop receiving the inquiry signal B from the mobile terminal 40, and the signal receiver will transmit the inquiry signal B to the alarm module 20 through the signal processor 32, and the vibration motor 21 and the generator 22...

Abstract

The invention belongs to the technical field of limited space operation safety monitoring, and particularly relates to a limited space operator safety monitoring device. The device comprises a wearable wristband and a mobile terminal, the wearable wristband comprises a working part and a wearing part, the working part comprises a processor module and an alarm module, and the processor module is used for measuring and calculating the instantaneous acceleration or deceleration action of the wearable wristband deviating from the original spatial position and sending a corresponding action signalto the mobile terminal; the mobile terminal comprises a signal module and an alarm, and the signal module is used for receiving the action signal and sending a corresponding processing signal to the working part and the alarm; and the processor module and the alarm are used for receiving the processing signal and performing corresponding alarm processing according to the type of the processing signal. Through cooperation of the wearable wristband and the mobile terminal, the physical conditions of operators can be effectively followed up and monitored, safety monitoring can be conducted on multiple operators on the same operation plane at the same time, and the working efficiency of monitoring personnel is greatly improved.
