The measuring method of lifting cross sliding type parking equipment exercise performance detector described in the utility model, comprises the following steps:

1, preparation: magnet base 3 is adsorbed on detected parking stall 1；Adjust 3-axis acceleration sensor 2 so that it is Z axis is along lifting direction, and X-axis is along traversing direction；

2, measure: the detected parking stall 1 of operation is traversing or lifts, and its operation can be run by automated manner, it is possible to runs manually, until the motion of detected parking stall 1 stops；3-axis acceleration sensor 2 Real-time Collection is detected the acceleration of motion numerical value of parking stall 1, and wirelessly transmits to kinematic parameter analysis system 4；After the motion of detected parking stall 1 stops, 3-axis acceleration sensor 2 stops gathering；

3, calculate:

(1) the acceleration a numerical value of 3-axis acceleration sensor 2 Real-time Collection is calculated acceleration a and changes over function A=A (t) by kinematic parameter analysis system 4 automatically；When parking stall is traversing, gathering X-axis acceleration value is Effective Numerical；During parking space elevating, gathering Z axis acceleration value is Effective Numerical；The present embodiment illustrates as a example by parking stall descending motion detects, and draws the acceleration plots that parking stall is run, as shown in Figure 2；

(2) kinematic parameter is analyzed system 4 and is integrated by A (t) function obtained, and obtains the speed of service function of detected parking stall 1:

V (t)=∫ A (t) dt

Thus, the speed curve diagram of detected parking stall 1 is drawn, as shown in Figure 3；

As can be seen from Figure 3, the AB stage is quiescent phase before parking stall declines, the BC stage be parking stall from static to the boost phase of uniform descent, the CD stage is the parking stall uniform descent stage, the DE stage is the decelerating phase that parking stall stops to braking from uniform descent, and the EF stage is parking stall quiescent phase after braking stopping；

The ideal process of parking stall descending motion is: static even acceleration declines the even decline stopping of slowing down of uniform descent, and its ideal speed curve is as shown in Figure 4；

By comparison diagram 3 and Fig. 4, the actual rate curve measured has different with ideal speed curve, and its reason is mainly affected by parking stall vibration during the decline of parking stall and 3-axis acceleration sensor 2 Acquisition Error；

(4) use method of least square that the actual speed curve obtained is carried out piecewise fitting, it is thus achieved that the velocity function of each motion stage, wherein:

1. before parking stall declines, the velocity fitting curve representation of static velocity band AB is:

V(t)_AB=K₁, K₁It is zero for numerical value after static front truck bit rate matching

2. the velocity fitting curve representation of parking stall even acceleration decrease speed region BC is:

V(t)_BC=K₂*t+K₃

3. the velocity fitting curve representation of parking stall uniform descent velocity band CD is:

V(t)_CD=K₄, K₄For uniform descent speed

4. the velocity fitting curve representation of parking stall decline braking velocity band DE is:

V(t)_DE=K₅*t+K₆

5. the velocity fitting curve representation of parking stall braking stopping velocity band EF is:

V_EF(t)=K₇, K₇Stopping speed for parking stall, after matching, numerical value is zero

K can be obtained respectively according to after measured rate curve data matching₁、K₂、K₃、K₄、K₅、K₆And K₇Numerical values recited, matching rate curve is as shown in Figure 5；

(5) detected parking stall 1 can be expressed as to motion end operation from setting in motion total time:

$t=\frac{K_7-K_6}{K_5}-\frac{K_1-K_3}{K_2}$

Parking stall declines acceleration magnitude and can be expressed as:

A₁=| K₂|

Parking stall Accelerating running distance is expressed as:

$S_1=\left|\frac{{K_4}^2-{K_1}^2}{2K_2}\right|$

Parking stall uniform descent speed can be expressed as:

V=| K₄|

Parking stall uniform descent distance is expressed as:

$S_2=\left|K_4(\frac{K_4-K_6}{K_5}-\frac{K_4-K_3}{K_2})\right|$

Parking stall braking acceleration size is expressed as:

A₂=| K₅|

Parking stall brake slide distance is expressed as:

$S_3=\left|\frac{{K_4}^2-{K_7}^2}{2K_5}\right|$

Parking stall declines total distance and is expressed as:

S=S₁+S₂+S₃；
