Abstract
The utility model relates to a universal vibration sensor, belonging to a vibration sensing measuring element. The utility model is mainly composed of a casing, a sensing element arranged in the casing and a control circuit. The casing is composed of the butt-joint of two cylinders provided with a semicircular notch; the sensing element is clamped on the mutually butt-joint faces of the two cylinders, and the casing is divided into two hemispherical chambers by the sensing element; the innerof the two chambers are respectively provided with steel balls with equal number. The utility model has the advantages of small volume and simple structure, and can induce vibration coming from any directions.
Description
The utility model relates to a kind of universal vibrating sensor, belongs to the vibrating sensing measuring component.
Vibrating sensor in the prior art, its primary structure are a spring oscillator, realize that by collision vibration induction picks up vibration signal, after processing of circuit, record vibration values.Its major defect is to have directivity, thereby reliability is relatively poor.
The purpose of this utility model is to overcome the defective that vibrating sensor in the prior art has directivity, designs a kind of universal vibrating sensor that all can pick up vibration signal of going up in any direction.
The purpose of this utility model realizes by following measure:
The utility model by housing and in sensing element and the control circuit established form, housing is docked mutually by two cylinders that are provided with semi-circular recesses to be formed, the sensing element that on the mutual interface of two cylinders, accompanies, housing is divided into two hemisphere chambers, in two chambers, respectively be equipped with the steel ball that quantity equates.
The utlity model has volume little, simple in structure, to the advantage of induction is all arranged from the vibration of any direction.
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is the utility model shell structure schematic diagram;
Accompanying drawing 3 is the control circuit figure of the utility model embodiment;
The utility model will be further described below in conjunction with accompanying drawing:
By accompanying drawing 1 and accompanying drawing 2 as can be known, the utility model by housing and in sensing element and the control circuit established form, housing 1 is docked mutually by two cylinders that are provided with semi-circular recesses and forms, the piezoelectric ceramic piece 2 that on the mutual interface of two cylinders, accompanies, it is divided into two hemisphere chambers to housing 1, in two chambers, respectively be equipped with six steel balls 3.The utility model has two lead-in wires, and one links to each other with piezoelectric ceramic piece, and as holding wire, one is connected with housing, as ground wire, by two lead-in wires the utility model is connected with control circuit.If the utility model is vertical the placement, and the steel ball 3 in housing 1 upper chamber will be pressed on the surface of piezoelectric ceramic piece 2, as long as vibration occurs, and the variation that steel ball 3 will produce pressure to piezoelectric ceramic piece 2, thus produce pulse voltage signal; If the level or the placement of tilting, steel ball 3 in housing 1 interior two hemisphere chambers all can be rolled into the both sides of piezoelectric ceramic piece 2 along sphere, can produce the variation of pressure to piezoelectric ceramic piece 2 equally, thereby produce pulse voltage signal, this signal enters control circuit after amplifying.Accompanying drawing 3 is a simple anti-theft circuit, and when article were moved, the utility model will produce pulse voltage, through control circuit, can send the electronics tweeting sound.
