Description

Technical Field

[0001] The invention belongs to the technical field of transformer substation distance measurement, and in particular relates to a distributed live distance measurement alarm device based on radar distance measurement and induction. Background Art

[0002] Various types of lifting equipment are used in the installation of equipment in substations. During the use of the equipment, the distance between the lifting equipment and other structures and structures in the station cannot be accurately estimated due to visual effects, which often causes accidental collision with other equipment. The situation is even more serious in the operating station. If there are operating equipment around, the lifting equipment cannot control the safe distance directly, which will directly lead to discharge, personal safety accidents and equipment failure. Therefore, it is of great significance to accurately measure the distance between the lifting equipment and other structures or equipment.

[0003] At present, the distance between the crane boom and other equipment during construction is mainly determined by manual experience or the use of a near-electricity alarm device. If the distance to the live body is determined by manual visual inspection, the error is large and the probability of deviation is also high. It is only applicable to work scenarios where the distance to the live body is much greater than the safe distance. When using a near-electricity alarm device for measurement, high-voltage magnetic field induction is generally used for early warning. However, in more complex environments such as high-voltage lines and substations, there are factors such as low work efficiency, scattered detection quality, and a single method. It is impossible to intuitively display the location of the strong electric field to the operator, and it is impossible to accurately measure the distance to the live body, resulting in low alarm efficiency.

[0004] In summary, the proximity alarm device needs to comprehensively consider the accuracy of the sensor, the stability of the control part, the response speed of the alarm part, and the reliability of the power supply part. Only in this way can it be guaranteed that the proximity alarm can play an effective safety protection role in actual use. Summary of the invention

[0005] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a distributed live-line distance measurement alarm device based on radar ranging and induction, which can strengthen the safety control of the site during the live-line construction process and reduce the possibility of safety accidents on site. The device has a certain adaptability to the harsh environment where the object to be measured is in darkness, dust, smoke, electromagnetic interference, toxicity, etc. Moreover, the device has a simple structure, a small size, reliable signal processing, rapid and convenient ultrasonic detection, simple calculation, and easy real-time control.

[0006] The present invention solves the technical problem by the following technical solutions:

[0007] A distributed live distance measurement alarm device based on radar ranging and induction, characterized by: comprising an ultrasonic module, an electromagnetic induction module, a data processing CPU, a wireless communication module, an alarm module and a digital display module;

[0008] The ultrasonic module uses the ultrasonic echo positioning principle to receive the echo signal of the device under test. When the electromagnetic induction module receives the electromagnetic field of the alarm module using the electromagnetic induction principle, the induction coil of the electromagnetic induction module generates an induced current to identify the nearby charged body.

[0009] The data processing CPU integrates and calculates the information of the ultrasonic module and the electromagnetic induction module through the wireless communication module, obtains the real-time distance between the measured object and the adjacent charged body, and sends instructions to the alarm module and the digital display module in time.

[0010] Moreover, the wireless communication module is integrated into the alarm device, and the ultrasonic module and the electromagnetic induction module are fixed at the highest point of the lifting equipment to measure the distance to adjacent equipment in real time.

[0011] Moreover, several of the ultrasonic modules and electromagnetic induction modules are respectively connected to the tested equipment. The ultrasonic modules and electromagnetic induction modules detect whether the equipment is charged and feed back the detected information to the data processing CPU in real time through the wireless communication module. The data processing CPU integrates and calculates the obtained information to obtain the real-time distance between the tested object and the adjacent charged body and feeds it back to the digital display module. At the same time, the distance is compared with the alarm distance value set under different voltage levels. When the alarm value is reached, an instruction is issued to the alarm module and the digital display module; the digital display module uses LCD to display the real-time distance, and when the alarm module receives the alarm instruction sent by the data processing CPU, it triggers the buzzer alarm to remind the operator to brake.

[0012] The advantages and beneficial effects of the present invention are:

[0013] 1. The present invention is not limited by the space and distance in the substation and can realize the synchronous testing of multiple devices at a long distance. It can be mainly used for substation renovation and expansion projects and nearby high-voltage circuit construction.

[0014] 2. For adjacent point construction in the same area, the present invention can realize simultaneous batch testing of multiple units, and only requires one person to operate, greatly reducing manpower and time costs.

[0015] 3. The present invention adopts 5G wireless communication technology, which has the characteristics of large capacity and low latency, and can quickly transmit the status of charged bodies around the device under test to identify safety hazards within the operating range.
