The invention provides a splicing type collimating mirror adjustment device and method, comprising: a connecting flange fixed on the back of the collimating mirror, an adjusting ball seat fixed on the connecting flange, a locking screw installed on the connecting flange, and a lock Lock nuts, fixing seats, rear ball pads and adjusting screws connected by tight screws. Wherein, the surface of the adjusting ball seat is a spherical surface. The rear ball pad is installed on the surface of the fixed seat facing the adjusting ball seat. The surface of the rear ball pad facing the adjusting ball seat is a spherical surface, which is used to limit the movement of the adjusting ball seat. One end of the adjustment screw is connected to the fixed seat, and the other end is against the surface of the connecting flange, which is used to rotate the collimator mirror in azimuth and pitch. The locking screw runs through the middle of the adjusting ball seat, the rear ball pad and the fixing seat. The locking nut is threadedly connected to one end of the locking screw passing through the fixing seat, and is used for locking the relative position of the fixing seat and the connecting flange. The invention can effectively improve the adjustment efficiency and energy utilization rate of the unit collimating mirror.

The invention discloses a microscopic spectrum measurement device and method based on an optical chip substrate. Microscope, dichroic mirror, imaging lens and CCD image sensor. The method is as follows: prepare a wide-spectrum coupling object-loading optical chip with dispersion function; the laser light emitted by the illumination laser source is expanded and then reflected and focused on the object to be measured on the chip by the near-end mirror and focusing microscope objective lens; The emitted signal will be bound to the surface of the wide-spectrum coupling object-carrying optical chip and exit downwards at multiple angles. After being received by the collecting microscope objective lens and reflected by the dichroic mirror, it will be imaged by the imaging lens on the image sensor. Calculated Get the spectral signal of the object to be measured. The invention solves the technical problems of slow collection speed and low analysis efficiency in traditional spectrum measurement.

A buffer mode-based mass accounting intermediate message processing method, increase the record for accounting intermediate message, each time the user's accounting intermediate message received, the on-line accounting information of the user may be updated, and adopt the buffer mode accounting intermediate message processing method, through the buffer queue, isolate the accounting intermediate message processing from the normal accounting initial message and accounting final message processing, the technical process flow for buffer mode accounting intermediate message processing: with the control module: the protocol analysis module is configured for receiving the accounting message; the protocol analysis module may standardize the accounting message and put it into the buffer queue; the protocol analysis module may not wait the intermediate message processing, directly send the accounting response to the BRAS; the intermediate message processing module may read the data of buffer queue; and save the intermediate message information into the database.

The invention relates to a continuous ramming type seismic source device, which is mainly composed of a rack, wheels, a handrail, a heavy hammer, a connecting shaft type bottom plate, a baffle plate, a reset spring, a hinge pin, a T-shaped rod, a semicircular arc clamping groove, crank shafts, a big gear, a small gear, a worm wheel, a worm, a three-phase asynchronous motor and a counter weight, and is characterized in that the middle part of the heavy hammer is provided with a center hole, and the heavy hammer is fixed on the connecting shaft type bottom plate through the baffle plate; the connecting shaft bottom plate is connected with the T-shaped rod through the hinge pin; the T-shaped rod and the semicircular arc clamping groove fixed on the crank shafts form an intermittent motion mechanism; the whole device is fixed on the rack equipped with the handrail and the wheels; and the three-phase asynchronous motor drives the two crank shafts, which are arranged in a left-right symmetric manner and are fixedly connected to the semicircular arc clamping groove, to rotate. The continuous ramming type seismic source device enables the heavy hammer to ram the ground continuously so as to generate continuous controllable pulse signals, and has the advantages of high impact efficiency, adjustable interval, accurate impact force and time-delay-free output signal; and the continuous ramming type seismic source device is small in size, simple in structure, convenient to transport and transfer, and applicable to a complex terrain where field large-scale seismic source equipment cannot operate.
