Before, most of electric knife power output calibrating installation on the market is import equipment, price typically all costly, condition
And maintenance there is also it is certain the problem of；The producer of domestic production electric knife power output calibrating installation is fewer, detection essence
Degree is also inadequate, and stability is poor, and therefore, there is an urgent need to develop a kind of economical and practical electric knife power output calibrating installation.
The content of the invention
The purpose of this utility model is to solve above-mentioned problem, and spy provides a kind of electric knife power output
Calibrating installation.
A kind of electric knife power output calibrating installation, including load box 1, multicircuit relay 2, energy conversion module 3, mistake
Thermal protector 4, high-speed sampling module 5, singlechip controller 6, driver 7, control cabinet 8, wherein：Load box 1 is successively through multichannel

Device 6 controls multicircuit relay 2 through driver 7, control cabinet 8.
Further, in addition to PC 9, the PC 9 are connected by serial ports with singlechip controller 6.
Further, the noninductive resistance that the load box 1 is fixed by 8 resistances is in series, the resistance point of noninductive resistance
Wei 10,50,100,200,400,800,1600,3200.
Further, hot-cast socket type RMS to DC special chip of the energy conversion module 3 from Linear Tech
LT1088, LT1088 have wider frequency bandwidth.
Further, the high-speed sampling module 5 is from the AD7705 of AD companies, and its resolution ratio is 16, non-linear essence
Spend for 0.003%.
The advantages of the utility model：Electric knife power output calibrating installation described in the utility model is cheap, calibration

Brief description of the drawings
Fig. 1 is the structural representation of electric knife power output calibrating installation.
Fig. 2 is energy conversion module circuit diagram.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Fig. 1-2 is referred to, the utility model provides a kind of technical scheme：A kind of electric knife power output calibrating installation,
Including load box 1, multicircuit relay 2, energy conversion module 3, overheat protector 4, high-speed sampling module 5, singlechip controller
6th, driver 7, control cabinet 8.Wherein：The effect of load box 1 is simulation human body resistance, and is lowered into the voltage of detector.By
In the power that electric knife exports very greatly and as the change of power output, its output impedance are also not quite similar.In order to simulate just
The resistance value the application of ordinary person's body when undergoing surgery has selected high accuracy and the variable load box 1 of resistance, and load box 1 is by 8
The noninductive resistance that resistance is fixed is in series, the resistance of noninductive resistance is respectively 10,50,100,200,400,
800th, 1600,3200, resistance Adjustment precision is high, is also easy to adjust.Multicircuit relay 2 controls the resistance of load box 1 short
Connect, so as to reach the purpose of the control resistance of load box 1.
The effect of energy conversion module 3 is that the high-frequency ac voltage of electric knife is converted to the direct current that can be measured
Pressure.Energy conversion module 3 has wider from hot-cast socket type RMS to DC the special chip LT1088, LT1088 of Linear Tech
Frequency bandwidth, input is converted into heat to resistance heating, by a small amount of external circuit, thermal signal is converted into direct current by it
Voltage output.The operation principle of energy conversion module 3 is as follows：Vin ends are voltage input end, and input voltage is to LT1088 internal resistances
R1 is heated.Diode D1 measures R1 temperature, and temperature is higher, and its tube voltage is lower.The decline of D1 tube voltages, makes that amplifier A1's is defeated
It is no longer zero to enter voltage.Voltage difference produces a DC voltage and resistance R2 is heated after A1 amplifies, thermometric diode D2 pipe
Voltage decreases.At this moment, because the DC voltage of amplifier A1 outputs can be more than the virtual value of input voltage, so resistance R2 is not
It is disconnected to be heated, and firing rate is more than R1.The tube voltage fast approaching of two diodes, amplifier A1 input voltage convergence can be made
In zero.Now, caused heat is identical on two resistance, and output voltage is equivalent to the virtual value of input voltage.
The purpose of overheat protector 4 is to prevent that input voltage is excessive, causes to burn chip LT1088, serves certain guarantor
Shield acts on.High-speed sampling module 5, which is converted to the DC simulation signal that energy conversion module 3 exports, is available for what digital circuit was handled
Data signal, and deliver to singlechip controller 6 and be further processed.High-speed sampling module 5 selects the AD7705 of AD companies, its
Resolution ratio is 16, nonlinear precision 0.003%.Singlechip controller 6 is driven according to the parameter of setting by driver 7
Multicircuit relay 2 in control cabinet 8, adjust the resistance value inside load box 1.Also include PC 9, PC 9 passes through serial ports and list
Piece machine controller 6 connects, and testing staff can pass through the Labview Interface Controls singlechip controller 6 on PC 9, user
Just.
Above-described embodiment, a simply example of the present utility model, be not for limit implementation of the present utility model with
Interest field, all technical schemes identical or equivalent with content described in the utility model claims, all should be included in this practicality
In novel protected scope.
