Description

Technical Field

[0001] The utility model relates to the technical field of transformer substation operation area protection, in particular to an aerial offside alarm device. Background Art

[0002] The substation operating area is a place where safety is paramount. High voltage electricity, electromagnetic fields, and other dangerous factors may exist, so workers must wear appropriate personal protective equipment, such as hard hats, insulating gloves, and insulating shoes. Various safety warning signs and protective facilities are also typically installed within the operating area to remind workers to be vigilant.

[0003] However, in work areas involving high-altitude operations, such as cranes and other high-altitude work equipment, it is impossible to completely guarantee that other adjacent work surfaces will not interfere when they are controlled in the air. Especially in dangerous work areas such as substations, aerial overstepping must be completely avoided. Utility Model Content

[0028] The following is combined with Figure 1-2 The utility model is described in further detail.

[0029] Example 1

[0030] Reference Figure 1 and Figure 2 , an air offside alarm device of this embodiment includes: an integrated control operation box connected to a control center, and a control center display module;

[0031] An integrated control operation box is equipped with a radar detection module, a high-definition video monitoring module, an analysis and control module, and an audio and visual alarm module;

[0032] The integrated control operation box is set as a rectangular box, and the bottom of the integrated control operation box is provided with auxiliary fixed pulleys, and there are four auxiliary fixed pulleys distributed on the four corners of the bottom of the integrated control operation box;

[0033] The radar detection module is configured to detect the distance of the target to be crossed that enters the warning area; specifically, it includes a radar detector arranged on the integrated control operation box, and the radar detector is detachably installed on the upper side of the integrated control operation box. The radar detector is configured to cover the warning area. The radar detector emits electromagnetic waves into the area to be detected and receives electromagnetic wave signals reflected by the target to be crossed to obtain the distance of the target to be crossed. At the same time, it can also obtain information such as the speed of the target to be crossed.

[0034] The high-definition video surveillance module is configured to be able to perform video surveillance; specifically, it includes a high-definition surveillance dome camera and a pneumatic lifting mast on an integrated control operation box. There are multiple high-definition surveillance dome cameras. The bottom of the pneumatic lifting mast is connected to the vertical side of the integrated control operation box. The top of the pneumatic lifting mast is fixedly connected to a connecting plate. The connecting plate is set horizontally. All high-definition surveillance dome cameras are installed on the connecting plate, so that the top of the pneumatic lifting mast is connected to all high-definition surveillance dome cameras.

[0035] The analysis and control module is connected to the radar detection module and is configured to receive the distance signal of the target to be crossed, obtain the crossing signal by comparing it with the distance threshold signal, generate an alarm control signal according to the crossing signal, and generate a monitoring trigger signal according to the crossing signal; after controlling the high-definition video monitoring module to receive the monitoring trigger signal: turn on the high-definition monitoring ball camera; at the same time, control the high-definition monitoring ball camera to rotate in the direction of the target to be approached according to the position of the target, and control the pneumatic lifting mast to rise and fall in the direction of the target to be approached, so that the high-definition monitoring ball camera can accurately track the approaching target.

[0036] Reference Figure 3 The analysis and control module includes a cross-border information judgment unit, which includes a first comparison circuit, a first logic circuit, and a trigger circuit. The first comparison circuit receives a distance signal from a cross-border target and compares the distance to the target based on a distance threshold to generate a first comparison result. The first logic circuit performs a logical judgment on the first comparison result to obtain a first judgment result, which serves as an alarm control signal. The trigger circuit receives the first judgment result and generates a monitoring trigger signal. In this embodiment, U0 is the distance threshold signal, and U1 and U2 are the acquired target distance signals. Multiple distance signals may be included. When U1 or U2 is greater than U0, the first comparison circuit outputs a low level; otherwise, it outputs a high level. When one of the first comparison circuit outputs a low level, the first logic circuit outputs a high level. When all the outputs of the first comparison circuit are high, the first logic circuit outputs a low level. The trigger circuit is a transistor-controlled circuit. When the first logic circuit outputs a high level, the trigger circuit conducts, powering the high-definition video surveillance module and enabling its monitoring function. The audio and visual alarm module also uses transistors to control whether power is turned on.

In this embodiment, the speed of the target to be crossed can be tracked and different alarm sound volumes and lights can be set to enable the target to be crossed to respond and evacuate quickly.

[0039] The sound and light alarm module also includes a speaker, which is set in the integrated control operation box. After the staff speaks through the microphone in the control center, the sound will be emitted through the speaker;

[0040] The control center display module is connected to the data transmission module and is configured to display the tracking results of the approaching target in real time.

[0041] The implementation of the distance control in this embodiment is as follows: when a person or device enters the warning area, the radar detector is activated to detect the distance between the person or device and the near-electric zone. When the distance is less than a threshold, it is determined that the person or device is about to cross the boundary. At this time, the sound and light alarm is activated. At the same time, the person or device is monitored by a high-definition surveillance camera and displayed in real time at the control center. The staff of the control center issues an audible alarm through a loudspeaker to make the person or device stay away from the near-electric zone.
