Problems solved by technology

Although this solution realizes the intelligent collection of construction site information, it requires manual real-time observation of the images collected by the camera, which is time-consuming and laborious, and negligence is inevitable. It cannot completely prevent idlers from entering the construction site or under heavy construction equipment to avoid construction Unnecessary casualties caused by equipment accidents

Embodiment 1

[0020] Example 1: Such as figure 1 with 2 As shown, this embodiment relates to a security defense system based on audio signals, which is used to monitor whether there are irrelevant people staying in the area around the heavy construction equipment 4 to prevent casualties. The security defense system includes an audio transceiver 1, a sensing device 2, a remote computer, and an alarm device. The audio transceiver 1 and the sensing device 2 exchange information through audio signals, and the remote computer is used to receive audio through a wireless network. The transceiver device 1 monitors the collected data and remotely controls whether the alarm device at the construction site alarms. The audio signal mentioned can be sound waves or ultrasonic waves.

[0021] Such as figure 1 As shown, the audio transceiver is composed of a processor, a transmitting circuit and a relay circuit and is packaged in a box. The transmitting circuit includes an audio amplifier and an audio transmit...

Embodiment 2

[0030] Example 2: Such as figure 1 , 2 As shown, the security defense system uses audio signal ranging to achieve the purpose of real-time monitoring in non-secure areas. The specific steps are as follows:

[0031] ①First install the audio transceiver 1 on the heavy construction equipment 4. The specific installation location of the heavy construction equipment 4 depends on the type of the machine. It is usually installed on its hook or truss; then the sensing equipment 2 is distributed to Each construction worker can be specifically fixed on his helmet or worn on his waist; at the same time, an alarm device shall be arranged on the construction site and connected to a remote computer through a network cable or wireless network;

[0032] ②The 3m radius around the hook of heavy construction equipment 4 is all non-safe area 3, and all construction personnel staying in this non-safe area 3 are in danger;

[0033] ③ Afterwards, start each of the above unit components to make each unit co...

Abstract

The invention relates to a security system based on audio signals and an application method of the security system. The security system comprises an audio transceiving device, a sensing device, a remote computer and a field alarming device. The audio transceiving device is mounted on a heavy construction device. The sensing device is worn by construction staff. The audio transceiving device transmits audio signals outwards in real time, and covering radius of the audio signals is limited in an N-meter non-security area of the heavy construction device. When construction staff enters the non-security area and stays for a long time, the sensing device is triggered to feed an audio signal with only ID (identity) number back to the audio transceiving device after receiving the audio signals, and the remote computer judges whether the field alarm device needs to be started or not after receiving the abnormal information. The security system is simple in structure and low in cost, conditions in the non-security area of the heavy construction device can be fully monitored in real time, and staff casualty can be avoided effectively.

Description

Technical field [0001] The invention belongs to the field of engineering construction safety early warning, and specifically relates to an audio signal-based safety defense system used on heavy construction equipment and an application method thereof. Background technique [0002] With the rapid development of the national equipment manufacturing industry, in the construction of various roads, bridges, and housing constructions, as well as in the production and transportation of heavy industrial products, various heavy construction equipment, such as cranes, Tower cranes, excavators, hoists, pile drivers, etc. Due to the huge volume of the above-mentioned various heavy construction equipment, no matter whether the rope breaks or the construction equipment overturns, it will cause serious casualties and property economic losses in the construction area. [0003] In order to ensure the safety of the construction work site, technicians on the one hand improve the performance of heavy...
