Description

Technical Field

[0001] This utility model relates to the field of monitoring equipment, and in particular to a miniaturized wireless microseismic monitoring device that can accurately monitor seismic activity. Background Technology

[0002] Vibration damage to cultural relics is insidious and irreversible. Vibration monitoring, through its comprehensive chain of "real-time early warning, source tracing and control, scientific support, and data accumulation," can quickly respond to sudden vibration threats, preventing direct damage to relics, and manage continuous vibration risks in the long term, delaying aging and damage. It also provides quantitative data for the design and decision-making of cultural relic protection plans. In today's cultural relic protection landscape, which increasingly emphasizes "preventive protection" and "scientific management," vibration monitoring has become a core technological means connecting the preservation environment, protection projects, and management and utilization of cultural relics, and is an important guarantee for achieving "long-term preservation and sustainable utilization" of cultural relics. Currently, monitoring equipment uses a single sensor, but a single sensor has low monitoring efficiency and is not accurate enough. Utility Model Content

A first connecting adhesive layer is filled between the longitudinal detector 6 and the first mounting hole, and a second connecting adhesive layer is filled between the transverse detector 7 and the second mounting hole. The longitudinal detector 6 and the transverse detector 7 are existing monitoring sensors used to monitor vibration signals. The monitoring housing 1 and the monitoring cover 2 work together to seal the mounting bracket 3, circuit board 4, signal transmission module 5, longitudinal detector 6, transverse detector 7, and rigid fastener 8 within the monitoring housing 1 and monitoring cover 2. The signal transmission module 5 is existing technology and is fixed to the circuit board 4 to transmit signals.

Using advanced sensor technology, it achieves a 0Hz frequency response and a minimum noise level of 45μg / √Hz. It supports ultra-low power consumption mode, automatically shutting down when no data is being transmitted and waking up via vibration or a timer. A full charge provides up to 3 years of use.The sensor features a full aluminum alloy housing, meeting IP65 protection standards and providing resistance to electromagnetic interference and UV radiation, ensuring reliable operation over extended periods. It also offers a comprehensive MQTT interface protocol. Powered by a built-in high-capacity safety battery, it transmits data wirelessly to the server via 4G (fourth-generation mobile communication technology) and then synchronizes it to the platform. The terminal boasts advantages such as ultra-low power consumption, high accuracy, high reliability, good stability, and compact size.

[0028] In some embodiments, the circuit board 4 is electrically connected to the battery 11 via a switch 10. The battery 11 is disposed between the mounting bracket 3 and the bottom of the mounting cavity 9, and the switch 10 is fixedly mounted on the circuit board 4. A limiting groove 12 is provided on the bottom of the mounting cavity 9, and both the rigid fixing member 8 and the battery 11 are disposed in the limiting groove 12. Both the switch 10 and the battery 11 are prior art. The battery 11 provides power to the wireless micro-vibration monitoring device, and the switch 10 controls the circuit connection between the battery 11 and the circuit board 4. The limiting groove 12 is provided to mount the battery 11 and the rigid fixing member 8. The upper end of the battery 11 is pressed down by the mounting bracket 3 to prevent the battery 11 from shaking within the monitoring housing 1.

[0029] In some embodiments, a control hole 13 is provided on the side wall of the monitoring housing 1 to cooperate with the switch 10, and a screw plug 14 is sealed on the control hole 13. The switch 10 can be turned on or off through the control hole 13. In order to achieve a seal on the monitoring housing 1, a screw plug 14 is provided on the control hole 13. The screw plug 14 is threadedly connected to the control hole 13, and the screw plug 14 is removable from the control hole 13.

[0030] In some embodiments, the monitoring housing 1 is provided with a first sealing ring groove 15, and the monitoring cover 2 is provided with a second sealing ring groove that mates with the first sealing ring groove 15. An annular sealing ring 16 is provided between the first sealing ring groove 15 and the second sealing ring groove. The first and second sealing ring grooves are provided to accommodate the annular sealing ring 16, which is a rubber sealing ring in the prior art. Under the action of the annular sealing ring 16, a seal is achieved between the monitoring housing 1 and the monitoring cover 2.

[0031] In some embodiments, an antenna 17 is sealed on the outer wall of the monitoring housing 1, and the antenna 17 is electrically connected to the signal transmitting module 5. The antenna 17 is a prior art device, enabling signal transmission over longer distances.

[0032] In some embodiments, an indicator light hole 18 is provided on the outer wall of the monitoring housing 1, and a waterproof indicator light 19 electrically connected to the circuit board 4 is sealed inside the indicator light hole 18. The waterproof indicator light 19 is prior art and is used to observe whether the battery 11 has power. To prevent moisture in the air from entering the monitoring housing 1, the waterproof indicator light 19 is sealed to the monitoring housing 1.

[0033] In some embodiments, a fastening plate 20 is fixedly disposed on the side wall of the rigid fastener 8. The fastening plate 20 is provided with a fastening hole 21, and a locking screw 22 passes through the fastening hole 21 and is threadedly connected to the monitoring housing 1. Fastening plates 20 are provided on both sides of the rigid fastener 8, and each fastening plate 20 is fixed inside the monitoring housing 1 by three locking screws 22. This allows the rigid fastener 8 to fit better against the monitoring housing 1, resulting in more accurate monitoring results from the longitudinal detector 6 and the transverse detector 7.

[0034] In some embodiments, both the monitoring housing 1 and the monitoring cover 2 are housed within the protective cover 23 and do not contact the protective cover 23. Expansion screws are used to separately fix the monitoring housing 1 and the protective cover 23 to the object being measured. If the object being measured is relatively complex or difficult to fix, the protective cover 23 and the monitoring housing 1 can also be fixed to a mounting plate, which in turn fixes the device to the object being measured. This wireless micro-vibration monitoring device automatically shuts down when no data is being transmitted and can be woken up by vibration or a timer. Therefore, to reduce the risk of accidental activation due to excessive rain, falling rocks, or tourists touching the main body of the device, a protective cover 23 is installed around the device. The protective cover 23 is made of transparent engineering plastic, ensuring strength while also being aesthetically pleasing.
