Measuring instrument.
Existing closing of the door speed measuring equipment is owing to having been used up France Industechnic
Equipment measured by VFP-G II type that Group company produces, this equipment has following defects that 1,
Need during use could normally be worked by power supply power transformation device external 220V power supply；2, this sets
Standby terminal measurement module (using model is ARS-300 band sucked type angular-rate sensor), only
Can absorption use on door skin, it is impossible to as in car；3, this measurement equipment needs when using
Want controller and terminal measurement module to work simultaneously, due to device controller integrated power supply interface,
Power supply power transformation device, liquid crystal panel such as shows at the function, and volume is relatively big (175 × 230 × 83mm),
Cannot adaptive car door inner space (70 × 40 × 50mm) requirement.Therefore, existing car door
Closing velocity is measured equipment and can not be assembled to inside car door, it is impossible to meet wanting with car life-time service
Ask, more bother during use, and this equipment price is expensive, should not assemble in batches.
Utility model content
The purpose of this utility model is to provide a kind of opening/closing door of vehicle durable speed acquisition equipment, energy
Enough satisfied requirements with car life-time service.
The technical solution of the utility model is: a kind of opening/closing door of vehicle durable speed acquisition equipment, bag
Including power interface and data transmission interface, device interior is integrated with data acquisition module, angular velocity
Sensor, data transmit-receive module and can the mu balanced circuit of adaptive vehicle power, described mu balanced circuit
Input is connected with power interface, outfan and data acquisition module, angular-rate sensor, number
Connecting according to transceiver module, described angular-rate sensor signal output part is connected with data acquisition module,
Described data acquisition module is connected with data transmit-receive module, and described data transmit-receive module passes with data
Defeated interface connects.
Further, described angular-rate sensor is gyroscope.
The beneficial effects of the utility model are: integrated stable voltage circuit in a device, by input voltage
Stable 9.0～28.0V so that this equipment is when carrying out car door speed acquisition, it is not necessary to use
Power supply power transformation device external 220V power supply, can directly utilize vehicle power and power, and is conducive to car
Assembling uses.It is replaced as directly being assemblied in car door by traditional sucked type angular-rate sensor
The gyroscope in portion, further reduces the volume of whole equipment so that this equipment can be with vehicle commander
Phase uses.
Accompanying drawing explanation
Fig. 1 is this utility model catenation principle block diagram；
In figure: 1 opening/closing door of vehicle durable speed acquisition equipment, 101 data acquisition modules, 102

Interface, 106 data transmission interfaces, 2 PCs, 3 communication serial ports, 4 vehicle powers.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below
In conjunction with drawings and Examples, this utility model is further elaborated.Described herein
Specific embodiment only in order to explain this utility model, be not used to limit this utility model.
Additionally, technical characteristic involved in each embodiment of this utility model disclosed below
As long as the conflict of not constituting each other just can be mutually combined.
As it is shown in figure 1, in the opening/closing door of vehicle durable speed acquisition equipment 1 of this utility model employing
It is integrated with data acquisition module 101, angular-rate sensor 102, data transmit-receive module 103 and
Can the mu balanced circuit 104 of adaptive vehicle power 4.This data acquisition module 101 is for by angle speed
The output signal of telecommunication of degree sensor 102 is converted to digital signal, and to closing of the door momentary angular speed
Degrees of data carries out cumulative record, it is determined that action of every time effectively closing the door, and records having of stop of closing the door
Effect velocity amplitude, it uses high-performance MCU (microcontroller) integrated chip, and recordable 13568
Individual valid data.The angular-rate sensor 102 that the present embodiment uses is MEMS XRSb200R
Gyroscope, it can be assemblied on inner plate of car door, is converted by the angular velocity of rotation of car door operating shaft
For the signal of telecommunication of ratio output, by monitoring the amplitude size of its output signal of telecommunication, obtain it and depend on
The angular velocity of rotation of attached car door, its angular velocity measurement scope is 0～300.0 degrees second.Data are received
Send out module 103 to pass for the data between data acquisition module 101 and data transmission interface 106
Defeated.In order to enable the adaptive vehicle power of whole equipment, it is integrated with mu balanced circuit at device interior
