Problems solved by technology

Since the watch-type proximity alarm is worn on the hands of the staff, the purpose is to protect people's safety. If it is not suitable to install it on the crane, the operator of the crane operates in the cab, that is, the operator does not Not close to high-voltage lines, so it is not suitable for preventing cranes from colliding with high-voltage lines
[0006] 3. Tower crane safety protection system, the biggest feature of this device is that it can know the position and status of the crane in real time, so that the operator can fully understand the situation of the crane, but the system is expensive and complicated to install. For construction cranes, although the system can provide the position and status of the crane, the distance from the high-voltage line is still inaccurate, so it is not very suitable for crane operations

Embodiment Construction

[0027] For the convenience of explanation, the voice alarm and video monitoring device for the on-site operation anti-touch high-voltage line will be described in detail in conjunction with the accompanying drawings.

[0028] as attached figure 1 , attached figure 2 , attached image 3 , attached Figure 4 And attached Figure 5 As shown, the field operation anti-touch high-voltage line voice alarm and video monitoring device includes a CPU module 1, a measurement module 2, a power module 3, a wireless transmission module 5, a display module 9, a voice alarm module 7, and a video monitoring module.

[0029] The above seven modules are set on the reinforced base; the measurement module senses the electric field strength, and when the distance between the top of the crane and the high-voltage line is less than the set safety distance, the measurement module sends a signal to the voice alarm module and the monitoring module through the CPU module.

[0030] The CPU module 1 i...

Description

technical field [0001] The invention relates to the field of construction safety, in particular to an anti-collision warning device for high-voltage lines in field operations. Background technique [0002] Most of the hoisting machinery operations are in the working environment with electricity, and there are no due reminders whether the high-voltage equipment is live, whether the construction equipment enters the high field strength area, and whether it is close to the minimum safe distance specified in the regulations. In particular, the power system Construction workers outside of China often have relatively weak safety awareness, and they don't even have the concept of a safe distance for construction near high-voltage power equipment. Even if there are safety precautions, the safe distance between the boom and the high-voltage line is estimated by visual inspection when the hoisting machinery is operating. This distance measurement method usually causes large errors. I...
