It is sensor.Common seismic detector is generally adopted by speed and acceleration type cymoscope, by 27 needle adapters of cable and
Seismic detector connects, and the generally acceleration type sensor used by advanced prediction seismic detector, it is 4 pins（The public ground of 3 components
Line）Therefore 4 needle adapters are connected on seismic detector advanced for tunnel so as to reach common seismic detector by interface by adapter
The purpose of forecast.The company of domestic at present purchase TSP equipment and seismometer device simultaneously can be found everywhere, and overlapping investment is serious, and
This utility model is exactly to solve the problems, such as this overlapping investment.
Content of the invention
The purpose of this utility model is to provide a kind of simple structure, enforcement and is easily applied to seismographic advanced prediction and connects
Receive device converting interface.The conventional sensor of advanced prediction can be directly connected to general by the converting interface provided by this utility model
Seismic instrument on, you can realize cost-effective and can by common seismic detector be used for Tunnel prediction purpose.
To achieve these goals, the technical scheme that this utility model is taken is as follows：One kind is applied to seismographic advanced
Forecast receiver converting interface, including 27 pin universal seismograph interfaces；It is characterized in that：Also include four sensor jointings,
12 filter amplification circuit modules and power supply；Sensor jointing is four needle interfaces, and one of interface is by the company of sharing
Line is connected to the even number binding post of 27 pin universal seismograph interfaces, and other three interfaces connect a filter amplification circuit mould respectively
One odd number binding post of the input of block, the outfan of filter amplification circuit module and 27 pin universal seismograph interfaces connects
Connect, power supply is connected respectively with 12 filter amplification circuit modules.
The sensor internal structure for being applied to advanced prediction at present is piezoelectric ceramics, due to the piezoelectricity of piezoceramic transducer
Electric current is microampere order, and piezoelectric voltage is millivolt level, accordingly, it would be desirable to pass through translation interface of the present utility model signal is amplified, with
It is easy to seismic detector to record.
This utility model use when, sensor jointing is connected with sensor, 27 pin universal seismograph interfaces with
Shake instrument connection；The seismic signal of collection is sent to filter amplification circuit module from sensor by sensor jointing, passes through
Filter amplification circuit module is sent in seismic detector by 27 pin universal seismograph interfaces after amplifying again and is recorded.
This utility model is achieved and for sensor to be directly connected to commonly seismographic purpose by this utility model, is reached
Common seismic detector is used for the purpose of Tunnel prediction.The seismographic price of purchase high-performance is far below purchase advanced prediction at present
Both the price price of instrumentation differs nearly 5 times, therefore can save enterprise investment.Simultaneously because the production technology of sensor
Content is relatively low, and domestic production manufacturer is more, and degree of freedom of the enterprise on selection equipment is bigger.
