Description
The utility model relates to the surveying instrument in detection technique field, particularly a kind of can the surveying instrument reference field and the electrolevel of earth horizontal plane angle.
Background technology: people adopt the bubble surveyor's staff to come the measurement level more for a long time, and this method can only indicate whether the angle of the plane that fits with the surveyor's staff reference field and earth surface level is zero, and the angle of energy measurement surveyor's staff and big ground level not.Existing digital display surveyor's staff is to adopt capacitance type sensor, because the inherent characteristic of capacitance type sensor, its performance is stable inadequately.Its performance is subjected to the influence of sealing technology etc., therefore wafts at that time and temperature is waftd greatlyyer, and precision is difficult to improve.
The purpose of this utility model is to propose a kind of electrolevel, this instrument can the surveying instrument reference field and earth surface level between angle, and can show with the digital display mode, also can be sent to host computer or miscellaneous equipment, the scope of measurement is arbitrarily angled promptly 0～360 °.
The technical solution of the utility model is:
The instrument of a kind of surveying instrument reference field and the earth horizontal plane angle, this instrument comprises sensor first (1) and identical with it sensor second (2), and the substrate (3) of sensor installation first (1) and sensor second (2), data processing unit (4) and display (5) is characterized in that:
Sensor first (1) and sensor second (2) are two identical in structure force transducers, sensor is made of strain beam (6), foil gauge (7), weight (8) and sensor underframe (9), strain beam (6) is fixed on the sensor underframe (9), foil gauge (7) is attached to the root of strain beam (6) near sensor underframe (9), and at the other end of strain beam (6) weight (8) is housed;

Described sensor first (1), sensor second (2) can adopt semiconductor gauge or adopt paper tinsel formula foil gauge, also can use thick film strain material or MEMS technology.
The beneficial effects of the utility model are:
Electrolevel can the surveying instrument reference field and the angle of surface level and can digital display or send out, and operator's hand takes the reference field of instrument to fit to tested surface, just can directly read the angle of this plane and surface level.The utility model adopts two identical strain gauge transducers, because good stability, the life-span of strain gauge transducer are long, condition of work does not have strict demand etc., therefore is more suitable in widespread use.
The drawing explanation: Fig. 1 is the structural representation of electrolevel.Fig. 2 is the structural drawing of sensor first and second.
Below in conjunction with accompanying drawing the utility model embodiment is described further:
Fig. 1 is the structural representation of electrolevel.Electrolevel comprises sensor first 1 and identical with it sensor second 2, and the substrate 3 of sensor installation first 1 and sensor second 2, data processing unit 4 and display 5.
Sensor first 1 is installed on the substrate 3, the base of its length axes direction and substrate is perpendicular, sensor second 2 also is installed on the substrate 3, its length axes direction parallels with the bottom surface of substrate, substrate 3 is a rectangle, and data processing unit 4 is installed on the substrate 3 with display 5 near two sensors is fixing;
The structure of sensor first or second is among Fig. 2: sensor is made of strain beam 6, foil gauge 7, weight 8 and sensor underframe 9, strain beam 6 is fixed on the sensor underframe 9, foil gauge 7 is attached to the root of strain beam 6 near sensor underframe 9, and at the other end of strain beam 6 weight 8 is housed;
The principle of work of electrolevel: establishing the sensor weight is m, and acceleration of gravity is g, and the effective length of beam is l, and k is and relevant proportionality constants such as bridge pressure and material behavior then to work as the bottom surface and the water of substrate 3
When there is an angle theta on the plane, according to mechanical relationship: the bridge circuit of sensor first 1 is output as:
U1=KmglCos(θ+90°)=-KmglSinθ
And sensor second 2 is output as:
U2=KmglCosθ
Then according to above expression formula can in the hope of:
Tanθ=-U1/U2
So θ=Arc Tan (U1/U2)
According to the output U1 of sensor first 1 and sensor second 2 and the value of U2, just can calculate the size of trying to achieve angle theta.According to positive and negative number of U2 and U1, just can know place, θ angle quadrant simultaneously.
That is to say that base plate when electrolevel becomes one when arbitrarily angled with surface level, when promptly going the Measuring Object level with electrolevel, the output of sensor first and second angle with it becomes a funtcional relationship, utilizes microprocessor can calculate the size and the quadrant of living in of angle.
When data processing unit 4 is delivered in the output of sensor first 1 and sensor second 2, data processing unit 4 amplifies several millivolts signal, handle, calculate by A/D conversion and single-chip data, just can be in the hope of the value of angle theta size, and can deliver to digital display unit 5 and show, perhaps deliver to control computer so that recording processing of being correlated with and control.
Sensor first 1 and sensor second 2 can realize in different ways according to the purpose of using and the convenience of processing, for example: adopt realizations such as paper tinsel formula foil gauge, semiconductor gauge, thick film strain material and MEMS technology.
