Abstract

The utility model provides a record article impact recorder of the impulsive force of receiving. The device comprises a shell, a piezoelectric accelerometer arranged in the shell, and a recording mechanism consisting of an amplifying and sampling circuit, an A/D conversion circuit, a data processing circuit containing a display circuit and a printing circuit, and a data storage circuit, a control panel circuit, a monostable circuit and a clock circuit which are respectively connected with the data processing circuit. The device can immediately record the time when the equipment is impacted during transportation and the magnitude of the generated acceleration value, and can display the value through a display and/or print the value through a printer at any time.

Description

Collide registering instrument

The utility model relates to a kind of collision that goods carried are subjected in the transportation loading and unloading process, registering instrument of vibration situation of being recorded in.

Some precisions, main equipment instrument are equipped with the collision registering instrument usually in transportation, so as under the instant recording in transportation the situation of being collided, vibrating of these things of being freighted.Existing collision registering instrument mostly is mechanical greatly, as CN2321969 disclosed " impact shock survey record instrument ", CN2108928 disclosed " impact, vibration monitor ", their vibration transducer places the check weighing piece on the elastic bearing to serve as by one, and recording mechanism is constituted with the stylus point and the paper-feeding mechanism of this check weighing piece interlock by one.Though this mechanical collision register instrument is simple in structure, the data precision of record is low, and error range is big, the time keeping that friction takes place, and it is poor that the accekeration that is recorded of reflection is intuitively spent, and do not have reusability.

The purpose of this utility model is to overcome existing above-mentioned shortcoming of colliding registering instrument, provide a kind of and can note the time that is collided at any time, the size of the accekeration that produces during bump, and can be easily show and/or printer prints is that come out, reusable collision registering instrument by display screen.

The collision registering instrument of realizing the utility model purpose comprises housing, be located at shock transducer and recording mechanism in the housing, fast shock transducer be piezoelectric accelerometer, described recording mechanism amplifies sample circuit by the signal that joins with the piezoelectric accelerometer signal output part, the A/D change-over circuit that joins with this amplification sample circuit output terminal, show and the data processing circuit of print circuit and the data-storing circuit that is connected to this data processing circuit respectively with this A/D change-over circuit output terminal containing of joining, the control panel circuit, monostable circuit and clock circuit constitute, wherein, the output terminal of control panel circuit and the input end of monostable circuit join, the output terminal of monostable circuit joins with the input end and the data processing circuit of clock circuit respectively, and clock circuit and control panel circuit respectively have an input end and data processing circuit to join.

Principle of work of the present utility model is as follows:

Trigger monostable circuit by handling control panel during use, monostable circuit is subjected to triggering the back and connects data processing circuit and clock circuit, enters duty.When being subjected to the vibration bump, the pulse signal that accelerometer generates under the effect of external force is delivered to signal amplification sample circuit and is amplified into the A/D change-over circuit, the A/D change-over circuit is transferred to data processing circuit after with data-switching, data processing circuit reads the time signal of clock circuit when producing signal when receiving the data that the A/D change-over circuit transmits, the data that read are handled back one road again and delivered to storage circuit and store, display is delivered on another road and/or printer shows/prints.Thereby the time of the collision that realization will be taken place in the whole transportation, the size of accekeration write down at any time and preserve for calling.The data of being stored are carried out the zero clearing processing then can be realized reusing.

Described data processing circuit can select for use the single-chip microcomputer 89C51 of inexpensive practicality to serve as.

The utility model has the advantages that the size of the accekeration of time when can immediately note equipment and instrument is subjected to colliding, generation accurate and visually in transportation, and can show and/or come out by display at any time by printer prints.And can under the state of dead electricity, retain all records and repeated use.Alternative prior mechanical is collided registering instrument and is used.

Provide enforcement side of the present utility model below in conjunction with accompanying drawing.
