A kind of device based on steel spring and the avalanche of pulling force sensor detection Dangerous Rock Body, comprise several pulling force sensors, the two ends of each pulling force sensor all with an end fixed installation of a steel spring, the other end of each steel spring all is fixedly connected with a pedestal, and pedestal is fixed in the slotting of Dangerous Rock Body crack one side; Be equipped with wireless module on described each pulling force sensor, wireless module is connected with Receiving Host by wireless signal, and Receiving Host is connected with receiving terminal.
Described pedestal is T-shaped.
Described slotting is T-shaped for what match with pedestal.
Described Receiving Host is connected by wired or wireless mode with receiving terminal.
The utility model detection method, step is as follows: 1) on the Dangerous Rock Body crack, choose some tested points, in both sides, Dangerous Rock Body crack, fixedly install pedestal, connect by steel spring the high-precision pulling force sensor that peripheral hardware has wireless module, thereby before the Dangerous Rock Body avalanche occurs, the crack is continued growth and is caused pulling force increase between the crack, and pulling force sensor can spread out of the mode of this variation by wireless telecommunications; 2) data of the pulling force sensor of each monitoring point collection are sent to Receiving Host and process by wireless signal, realize the Real-Time Monitoring to the monitoring point, thereby form the wireless monitor network; 3) Receiving Host is each monitoring point delta data that receives, mode by wireless or wire communication transfers to receiving terminal, further Treatment Analysis, realization is graphical to data, provide tension variations curve between the crack, thereby realize the monitoring to the Dangerous Rock Body avalanche, mechanical property parameter basis for estimation accurately is provided.
The two ends of high precision pull sensor of the present utility model respectively fixedly mount a steel spring, the other end of steel spring is fixed on Dangerous Rock Body crack one side, when the crack continues to grow, between the crack, pulling force can increase, the data that pulling force sensor gathers and the wireless module by peripheral hardware, by the mode of wireless telecommunications, send data to Receiving Host; Accept main frame and accept and complete the numeral conversion of analog signals, further be wirelessly transmitted to the receiving terminal, then by specific software, provide the size variation curve of pulling force between the crack; The relevant judgment criterion of being open to the custom, thereby the trend of prediction Dangerous Rock Body avalanche realize the purpose of efficient monitoring Dangerous Rock Body avalanche.
Pedestal is by the nested both sides, Dangerous Rock Body crack of being fixed in of the mode of slotting.The length of steel spring and concrete mechanics parameter can be according to the self-defined adjustment of actual monitoring crack geological state (and this self-defined adjustment is the known technology that those skilled in the art grasp).The range of pulling force sensor and precision are decided (range of pulling force sensor and precision are to well known to a person skilled in the art technology) by concrete Dangerous Rock Body geological state.Steel spring and pulling force sensor workmanship technique are sturdy and durable, satisfy the field environment requirements such as tamper-proof, waterproof, and energy continuous firing fortnight is the longer time even.The Receiving Host fixed in position is in safer fixed position point, in the open air longer time even continuous firing fortnight in common rugged surroundings.The data of whole system can realize fully that the wireless penetration of data transmits, and for the stability that guarantees data and the requirement of satisfying transmission range, can adopt the mode of wire communication between Receiving Host and receiving terminal.
The utility model utilizes the variation of mechanics parameter between the Dangerous Rock Body crack can accurately reflect this characteristic of Dangerous Rock Body avalanche, adopt high precision pull sensor and steel spring array mode, by setting up wireless sensor network, success and the monitoring of realization to the Dangerous Rock Body avalanche efficiently, have high precision, tamper-proof, antijamming capability is strong, measures the plurality of advantages such as convenient.
