Embodiment Construction

[0016] like figure 1 In the implementation example shown, the composition of the detection and alarm system includes:

[0017] 1. The monitoring server (101) is responsible for receiving the data uploaded by all laser scanning distance measuring devices and belt speed measuring devices in the system, and processing the data to obtain the running speed and running status of each belt, and connecting the control device of the belt to realize the control of the belt.

[0018] 2. The display terminal (102) is responsible for displaying the speed and running status of each belt.

[0019] 3. Core switching equipment (103), the core management and switching equipment of the data network, is responsible for the management and data exchange of all equipment connected to the wired network. If the network range is large, choose Ethernet networking, if the network is within a certain range , You can also use the field bus to build a network.

[0020] 4. The access switch device (104), t...

Abstract

The invention discloses a belt detection alarming system based on laser ranging, which adopts a noncontact measuring principle, and can effectively avoid the faults such as missing and error in report of a stroke switch measurement due to the influence of a contact environment. The system adopts a centralized data processing way, realizes the accurate measurement and monitoring simultaneously for multiple belts, the surface of a material is scanned by virtue of a laser scanning ranging device, a distance value from a laser head to the surface of the material is acquired, an edge position of each belt is acquired by virtue of the distance value, the edge position is compared with the belt edge position recorded when the device is calibrated, whether the belt is deviated or not can be judged, when the belt is deviated, a belt control device is notified to make corresponding action by transmitting a pulse control signal, and the belt device is prevented from being damaged. According to the system, fewer devices and parts are used, the structure is simple, the detection reliability is high, the system maintenance cost is low, and the belt detection alarming system is suitable for being popularized in various transport belt application industries.

Description

technical field [0001] The invention relates to a belt detection and alarm system based on laser ranging, and the system relates to the fields of laser ranging and communication. Background technique [0002] Conveyor belts are important equipment for short-distance transportation of materials, and are widely used in mining, agriculture, food, tobacco and other production industries. Belt deviation is the most common fault in the process of transporting belts. It is extremely harmful and mainly affects the following aspects: belt deviation causes system failure to stop and affects production efficiency; it is easy to cause abnormal damage to the main components of the equipment; The spillage of materials caused by the deviation of the belt is likely to pose a safety hazard. Therefore, timely and accurate detection of belt deviation is of great significance. At present, the main method of belt deviation detection is to use the deviation detection switch, that is, the travel...
