Brief introduction: Blasting vibration monitor l20-n is a wireless network blasting vibration meter specially designed for engineering blasting produced by jiaobo technology. Blasting vibration monitor l20-n is used to evaluate the impact of vibration caused by blasting construction on adjacent buildings, facilities and equipment. The remote monitoring system based on 4G network is suitable for the blasting vibration monitoring project with fixed measuring points and long-term monitoring. Advantages and characteristics: 1. Legal compliance. The vibration velocity value and the main vibration frequency of the three components were directly measured, which made the test results more accurate. The test method fully met the supervision requirements of the public security department and the blasting industry standards. 2. Leading technology. Based on the 24-bit acquisition technology, the sensor, vibration meter and mobile network and other components are highly integrated, which improves the stability and practicability of the instrument; 3. Network monitoring. Built-in 4G network, support wi-fi, LAN and other external network access, the operator can anytime and anywhere through the Internet remote access to the instrument, instrument control and file management and other operations; 4. Alarm and warning. Support the setting of alarm and warning events. When the amplitude exceeds the limit or the device is abnormal (power off, offline) and other events occur, the instrument will actively push the alarm message; 5. No measurement points. Square structure aluminum alloy shell, with dust, waterproof, impact resistance, can better adapt to the floor, side wall and top arch and other parts of the installation; 6. Easy to expand. Provide a complete communication packaging protocol, not only can be customized according to the user's personalized needs, but also can be seamlessly connected to the user's various Internet of things monitoring system. Technical parameters: Sampling rate: 1, 2, 5, 10, 50, 100Ksps can be set for parallel collection Resolution: 0.0001cm/s Frequency response range: 1-500hz Local communication: RJ45 interface network cable is directly connected to the computer, up to 2M/S without any Settings Network communication: full network access 2G/3G/4G wireless access, Lan/WAN/ADSL free networking wired access Alarm setting: power off/storage/amplitude SMS alarm Location setting: automatically obtain or manually set the location information of the measuring point Timing switch: set the working time to turn on/off the instrument Automatic zero correction: built-in zero correction program can automatically calibrate zero System upgrade: remote upgrade and maintenance of the system via data center or usb flash drive
