Abstract
An indicator for measuring the operating speed of cars aims to provide a measuring apparatus of vehicular speed which is installed in cars, to effectively remind drivers of driving safety, and to form effective supervision for the drivers by the recording ability of the apparatus. The indicator for measuring the operating speed of the cars of the utility model comprises a monolithic system, characterized in that the monolithic system is also connected with wireless receiving modules. The utility model can detect speed per hour of the cars by a singlechip, one receiving module which is connected to a data collection port of the singlechip can receive speed-restricting signals from an external transmitter and compare car speed data received from another receiving module of the singlechip which is connected with a sensor of speed per hour of the cars to further get the conclusion whether the car is over speed or not, and a signal switch module which is connected with a signal output port of the singlechip externally sends the message of the excessive speed of the cars by a standard signal of RS232.
Description
Technical field:
A kind of automobile-used driving speed prompting instrument of the utility model relates to the suggestion device that tests the speed of automobile.
Background technology:
At present, domestic communication department is for control, the correction of road speed; Usually adopt that GPS tests the speed, fixed radar tests the speed, mobile radar velocity measurement or locally implement monitoring, above-mentioned several modes all belong to the supervision of external environment condition to the driver, can not accomplish each driver is supervised in good time.
Summary of the invention:
The purpose of a kind of automobile-used driving speed prompting instrument of the utility model is to propose a kind of vehicle speed measurement device that is installed on the vehicle, can effectively remind driver drives vehicle safety, and by the record function of this device the driver be formed effective supervision.A kind of automobile-used driving speed prompting instrument of the utility model is to be made of the Single Chip Microcomputer (SCM) system that can detect the speed per hour of vehicle in good time, it is characterized in that described single-chip microcomputer also is connected with the radio reception module; The receiver module that the Data Receiving port of single-chip microcomputer is connected can receive the restricting signal that extraneous transmitter sends, and the vehicle speed data contrast that the receiver module of speed sensors obtains when another of single-chip microcomputer is connected automobile draws the conclusion that whether exceeds the speed limit, the signal conversion module that signal output port connected of single-chip microcomputer transmits the information of the overspeed of vehicle RS232 signal with standard to the external world, the information that is transmitted comprises the speed of vehicle, the recognition coding of time and speed prompting instrument itself.
Description of drawings:
Fig. 1 is the one-piece construction figure of a kind of automobile-used driving speed prompting instrument of the utility model.
Fig. 2 is the chip structure figure of a kind of automobile-used driving speed prompting instrument of the utility model.
Embodiment:
As shown in Figure 1, a kind of automobile-used driving speed prompting instrument of the utility model is by single-chip microprocessor MCU, clock module, E
2Prom memory, communication module RS-232 interface circuit, less radio-frequency receiver module, current require speed to show and during hypervelocity voice warning circuit form.As shown in Figure 2, the data reception module end 2 of a kind of automobile-used driving speed prompting instrument single-chip microcomputer 1 of the utility model connects the less radio-frequency receiver module; The LED display circuit of single-chip microcomputer 1 interface end constitutes display module 3; The chip data line of 1 port tie-time of single-chip microcomputer module 4 offers the single-chip microcomputer time of incident accurately; Speed sensors 5 when single-chip microcomputer 1 port connects automobile reads motoring condition in real time; Speed per hour when storage module 6 chips that single-chip microcomputer 1 is connected have write down overspeed driving car and speed limit at that time require and the time violating the regulations; The transport module 7 that single-chip microcomputer 1 is connected adopts RS232 signal outputting standard; The single-chip microcomputer output port can also connect sounding, luminous panalarm, offers driver's sound and light of alarm.Enforcement of the present utility model, need cooperate in road side the restricting signal emitter is installed, single-chip microcomputer is received restricting signal by the less radio-frequency receiver module, speed per hour contrast with the automobile that records itself, when exceeding the speed limit, running car notes hypervelocity information, and can provide audible alarm at that time, the signal conversion module that signal output port connected of single-chip microcomputer transmits the information of the overspeed of vehicle RS232 signal with standard to the external world, the information that is transmitted comprises the speed of vehicle, the recognition coding of time and speed prompting instrument itself.The storage module of a kind of automobile-used driving speed prompting instrument of the utility model can store number of times and concrete each data of hypervelocity information for a long time, the traffic police can read the storage data of single-chip microcomputer by the RS232 port, thereby effectively stops the driver because idea of leaving things to chance is implemented the generation of overspeed situation.
Claims (2)
1. an automobile-used driving speed prompting instrument is to be made of the Single Chip Microcomputer (SCM) system that can detect the vehicle speed per hour in good time, it is characterized in that described single-chip microcomputer also is connected with the radio reception module; The receiver module that the Data Receiving port of single-chip microcomputer is connected can receive the restricting signal that extraneous transmitter sends, the receiver module of speed sensors when single-chip microcomputer also is provided with a connection automobile, the signal output port of single-chip microcomputer are connected with signal conversion module and transmit to the external world with the RS232 signal of standard.
2. a kind of automobile-used driving speed prompting instrument according to claim 1 is characterized in that, can connect sounding, luminous panalarm in single machine output end.
