For baroceptor, before using, to detect it and whether satisfy accuracy requirement.Whether conventional detection generally provides a vacuum pipe with atmospheric pressure value, detects the atmospheric pressure value of this vacuum pipe by baroceptor, and qualified by this baroceptor of operator's artificial judgment.Because whether qualified baroceptor is is artificial judgment, detection efficiency is low and not directly perceived.
Summary of the invention
Technical matters to be solved by this invention is, overcomes the deficiencies in the prior art, provides detection efficiency high and baroceptor checkout equipment intuitively.
The technical solution adopted for the present invention to solve the technical problems is: this baroceptor testing apparatus comprises worktable, test fixture, be built-in with the circuit board of trace routine, vacuum pipe, be used to provide the vacuum breaker of two vacuum pressure values, standard pressure sensor and air pressure detection piece, this test fixture is installed on this worktable, this circuit board is positioned on this circuit board, this circuit board is connected with display screen and has a baroceptor installation position, the vacuum slot of this standard pressure sensor and vacuum pipe links to each other, this vacuum breaker is connected with this vacuum pipe, this air pressure detection piece connects this vacuum pipe, and this circuit board also is connected with display screen.
Described vacuum breaker comprises first vacuum breaker and second vacuum breaker, and this first, second vacuum breaker is all by switch and this vacuum pipe switched conductive.
Described switch is a T-valve, and three ports of this T-valve connect first vacuum breaker, second vacuum breaker and vacuum pipe respectively.
Described air pressure detection piece is a multimeter.
The invention has the beneficial effects as follows, by setting first, second vacuum pressure value, and according to the magnitude of voltage of corresponding output, can determine the linear ratio relation between atmospheric pressure value and the magnitude of voltage, during detection, only sensor to be measured need be placed on the circuit board, and unlatching vacuum pipe, can intuitively draw testing result by display screen, and owing to testing process does not need manually to participate in, so also improved detection efficiency.
Description of drawings
Fig. 1 is the structural representation of the utility model baroceptor checkout equipment.
Fig. 2 is the detection theory diagram of the utility model baroceptor checkout equipment.
Fig. 3 is the schematic diagram of linear ratio relation between reflection atmospheric pressure value and the magnitude of voltage.
Embodiment
See also Fig. 1 and Fig. 2, whether the utility model baroceptor testing apparatus is used for the detected air pressure sensor qualified, and this equipment comprises worktable 1, test fixture 2, computer 3, circuit board 4, vacuum pipe 5, standard pressure sensor 6 and air pressure detection piece 7.This worktable 1 is used to provide entire equipment to support, and this test fixture 2 is installed on this worktable 1, and it is used for locating circuit board 4.This computer 3 has input block (as keyboard) and display unit (as display screen).This circuit board 4 is connected with this computer 3, and this circuit board 4 is built-in with trace routine and is provided with the baroceptor installation position, and baroceptor to be measured promptly is installed on the baroceptor installation position of this circuit board.This vacuum pipe 5 is used to provide vacuum.The vacuum slot of this standard pressure sensor 6 and vacuum pipe 5 is connected.The multimeter 7 of this air pressure detection piece 7 as existing detected air pressure, this air pressure detection piece 7 detects the vacuum values of vacuum pipe 5.
This testing apparatus also comprises first vacuum breaker 8, switch 10 and second vacuum breaker 9, the vacuum values that this first, second vacuum breaker 8,9 is used to regulate vacuum pipe 5, it all is connected with vacuum pipe 5 by switch 10, can realize the switched conductive of this first, second vacuum breaker 8,9 and vacuum pipe 5 by this switch 10.This switch 10 is as T-valve 10, and its three ports connect first vacuum breaker 8, second vacuum breaker 9 and vacuum pipe 5 respectively.
Please in conjunction with consulting Fig. 3, during use, the vacuum slot of this vacuum pipe is connected with the standard pressure sensor, set the first vacuum pressure value of vacuum pipe by first vacuum breaker, this moment, multimeter was read this first vacuum pressure value C1, and this standard transducer then is converted to air pressure magnitude of voltage V1 and demonstrates this magnitude of voltage V1 on display screen; Then, switch by switch, second vacuum breaker is communicated with vacuum pipe, set the second vacuum pressure value of vacuum pipe by second vacuum breaker, this moment, multimeter was read this second vacuum pressure value C2, and this standard transducer then is converted to this air pressure magnitude of voltage V2 and demonstrates this magnitude of voltage on display screen.Because above-mentioned magnitude of voltage and atmospheric pressure value has linear relationship, so can draw the linear ratio relation between this magnitude of voltage and the atmospheric pressure value according to this first, second magnitude of voltage V1, V2 and first, second atmospheric pressure value C1, C2, can obtain corresponding atmospheric pressure value according to magnitude of voltage by this linear ratio relation.After having determined the linear ratio relation between atmospheric pressure value and the magnitude of voltage, set the upper and lower initial value of the magnitude of voltage of baroceptor to be measured by computer on circuit board, this upper and lower initial value is to set according to the accuracy requirement of baroceptor to be measured.At last, baroceptor 11 to be measured is placed on the circuit board and with vacuum slot is connected, this moment a given standard the vacuum pressure value, then can demonstrate corresponding voltage value on the display screen, be in as this magnitude of voltage between the upper and lower initial value of setting, then display screen shows that this baroceptor to be measured is qualified; Be in as magnitude of voltage outside the upper and lower initial value of setting, then display screen shows that this baroceptor to be measured is defective.
In the present embodiment, by setting first, second vacuum pressure value, and, determined the linear ratio relation between atmospheric pressure value and the magnitude of voltage according to the magnitude of voltage of corresponding output.During actual detected, only sensor to be measured need be placed on the circuit board, and open vacuum, can intuitively draw the whether qualified information of this sensor to be measured by the display screen of computer.
Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field; under the prerequisite that does not break away from the utility model design; can also make some simple deduction or replace, all should be considered as belonging to the scope of patent protection that the utility model is determined by claims of being submitted to.
