Description of the invention: [Technical field to which the invention pertains] A driving speed warning system, in particular, a two-stage driving speed warning system. [Prior Art] The prior art driving speed warning system is generally installed on a vehicle. The installation, sensing and warning methods are as follows: _ First, a speed measuring radar sensor is mounted on the vehicle in front of the induction vehicle. When there is a car speed radar, it will sound a warning or play the built-in warning voice. Secondly, receiving a satellite signal through a Global Positioning System (GPS) to obtain the latitude and longitude coordinates of the location of the vehicle, and matching the speed limit data of the road section of the vehicle from the road database, and then The instantaneous speed of the vehicle is calculated by the change of the latitude and longitude coordinates and compared with the speed limit data. When the vehicle is overspeed, the relevant warning message is output, the warning sound is issued, or the built-in warning voice is played. However, the prior art has problems that are difficult to overcome: First, the commercially available speed radar sensor is only for detecting the predetermined range of electric power, and informs the driver that there is a car speed radar in the road ahead. However, it fails to remind the vehicle of the current speed and the speed limit of the road section. In addition, even if the vehicle does not overspeed, as long as the vehicle speed radar is sensed, the speed radar sensor emits a warning sound or a warning voice, and the frequency is high, but instead Drivers can't concentrate on driving, which seriously affects driving safety. 200935367, the second commercially available speed-adjusting radar sensor and global satellite positioning device did not inform the driver of the current vehicle's speed exceeding the road speed limit. At most, the display interface displays the current speed and road speed limit. However, the driver needs to shift his gaze to see the information displayed on this interface. 'The speedometer will then check the current car shortage.' Speed (4) The speed of the thief is fast. This will easily cause the driver to divide...and thus improve the risk of driving, strict [invention Contents] “Ding Zao's Queen Ο There is a bell here, the invention is to solve the problem of providing a root speed situation to issue different levels of warning signals and to avoid disturbing the driver's speed warning system. The rain solves the above-mentioned system problem, and the technical means provided by the present invention is to expose the segmented vehicle over-speed police system to monitor the vehicle in the driving path: limit==廑::--alarm module, one speed providing module, -dao' Bei;: β Han 1 star positioning receiver module and - speed comparison module. One of the database vehicles, the instantaneous speed data; the road speed limit ^ / at least - the road and its corresponding road speed limit social security guard position receiving wedge group receiving vehicle is in the region - latitude and longitude = and match the road speed limit database To obtain the corresponding road speed limit data punch value; the speed comparison module judges the instantaneous speed data minus the road == material is zero or positive value seasonal warning module output - overspeed warning sound or output value warning sound. The two-stage rod straight buckle-limit data H disclosed in the invention has a road speed library and a speed limit buffer value, and the speed ratio of the dragon group determines the instantaneous speed of the 200935367 degree data minus the road limit data is positive and less than the speed limit. When the buffer value, or the value above the speed limit buffer value, is output, a difference warning sound or a severe overspeed warning sound is output. These warnings are warnings to inform the driver of the vehicle that the current vehicle exceeds the road speed limit. The second stage of the vehicle speed warning system disclosed in the present invention further comprises a speed limit correction module and a speed sensor, and the speed limit correction module has a control interface for the user to update the speed limit buffer value and Road speed limit data, ❹ speed radar sensor is the speed limit data of the speed limit monitoring station of the inductive car surface such as the square road section, and the speed limit correction module matches the speed limit data with the road speed limit data of the satellite positioning receiving module. In contrast, the road speed limit data of the road speed limit database is corrected when the comparison results are different. The two-stage driving speed warning system disclosed in the present invention has a speed providing module which is a driving computer of a vehicle, a vehicle speed meter, a driving recorder, and a time-shift pulse signal processor. Alternatively, the speed providing module is the satellite g receiving frequency calculated according to the change of the vehicle: (4). The invention has the effect that the prior art can't achieve. · By the combination of the road speed limit data and the speed limit buffer value, the speed comparison module only takes the road speed limit (four) as a positive value when the speed is reduced. = When the value above the speed buffer value is reached, the relevant singer sound is output to reduce the warning sound output frequency and avoid interference with the driver's to improve driving safety. Second, the speed radar sensor obtains the speed limit of the road section of the vehicle where the vehicle is located. The limit speed of the monitoring station is 200935367. In the speed limit correction mode speed limit database, the road speed limit of the stored road == the profit is broken. Automatic correction at the time, the road speed limit data of the disc-guaranteed road speed limit database, to avoid the driver being mistaken for the wrong road, • when driving, hindering the travel of other vehicles, or the shape is not 'Embodiment】 Awkward circumstances. In order to make the purpose of the present invention, it is necessary to knock down people: Μ 竹 做 做 做 做 做 ❹ ❹ ❹ ❹ ❹ ❹ ❹ ❹ ❹ ❹ ❹ ❹ ❹ ❹ ❹ ❹ ❹ ❹ ❹ ❹ ❹ ❹ ❹ ❹ ❹ ❹ ❹ ❹ ❹ ❹ ❹ ❹ ❹ ❹ 1 千千立闰Φ ^ 々 This is the schematic diagram of the system structure of the embodiment of the month, the light car does not think about and the warning signal output timing. The speed limit correction module b & type brake super-catch 7 system includes - speed providing module, - satellite positioning receiving module m, - speed comparison module 14 〇, a road speed limit database 130, - The warning module ι5〇, 170 and a speed radar sensor 16〇.迢 The road speed limit database 130 stores a speed limit buffer value and a road-to-road material limit data for a region. Road secrets (4) include the types of roads in this area (such as national roads, provincial roads, county roads, express roads, major roads, etc.), numbers (such as National Road No. 1, Provincial Road No. 3, County Road No. 17, etc.) and roads. The speed limit of the road section, the location of the car speed radar 201, and the latitude and longitude coordinates of the roads. The speed limit value is the area buffer value of the road speed limit reaching the speed limit of the actual speed measurement of the car speed radar 2〇1, generally for manual input. If the speed limit is 100 kilometers, the speed limit of the actual speed measurement of the car speed radar 201 is 110, so the speed limit of 200935367 is the input of the safety of the vehicle 10 can be driven to 109 100 as shown in Figure 1 and As shown, the satellite positioning receiving template is connected to the satellite signal transmitted by the star 300. The satellite signal contains the location of the vehicle's location - (4), and then the material is matched with the road capture limit 130 to determine the warp and weft data. Search for the road speed limit 'η犀130' to obtain the road section of the road where the vehicle 100 is located, the corresponding road data and the speed limit buffer value. The road speed limit data and the speed limit buffer value can be passed through - the speed limit correction 170 is amended, which provides - control (4) for the driver ^: the user manually inputs the correct and updated road speed limit data and the speed limit buffer value. The speed providing module (10) provides the vehicle when driving The speed providing module 120 itself is a two-way driving recorder of the vehicle, the time-range pulse signal processing i, and the downward positioning receiving module 11G are changed according to the vehicle (10) (four). Length of time to Calculate the instantaneous speed of the vehicle coffee ^ As shown in Figure 1 and Figure 3, the speed comparison module 140 is electrically = 4. The degree providing module 12〇, the charm positioning pure module 11G and the road fan ^ 130 (if the speed is provided The amount of 12 () is the satellite positioning receiver module, when the 'speed comparison module (10) only electricity _ satellite receiving position Γ 道路 and road speed limit database 13 〇).,,, and 110 this speed ratio For the module 140, you can correct the y-bit receiving mode t 11G P p ± so that she can use 12 () and the satellite to determine the instantaneous data, road speed limit data and ^ 200935367 buffer value, and according to the instant The speed data minus the difference between the road speed limit data to determine whether the vehicle is overspeed. If the vehicle is overspeed, the difference is positive, and then the positive value is matched with the speed limit buffer value to determine whether the vehicle is serious. Overspeed status. In this embodiment, the road speed limit data is 100 km and the speed limit buffer value is 10 km. The speed comparison module 140 is described as follows: (1) When the vehicle's instantaneous speed data is 95 km , representing the instantaneous speed data minus the road speed limit data is negative (95-100=-5), that is, the judgment The vehicle 100 is not overspeeded, and the speed comparison module 140 does not actuate the warning module. (2) When the vehicle's instantaneous speed data is 100 kilometers, it represents the instantaneous speed data minus the road speed limit data is zero (100-100= 0), whether the vehicle 100 is raised from a low speed to a high speed (such as 95 kilometers to 105 kilometers) or from a high speed to a low speed (such as 105 kilometers down to 95 kilometers), the warning module 150 outputs an overspeed warning sound. 3) When the vehicle's instantaneous speed data is 105 km, it means that the instantaneous speed data minus the road speed limit data is positive (105-100=5), and is below the speed limit buffer value but not zero (ratio When the mode is 5-10=-5, which is a negative value, it is determined that the driving speed of the vehicle 100 is above the road speed limit data but the speed limit buffer of the sum of the road speed limit data and the speed limit buffer value is not satisfied. That is, a difference warning sound is output. (4) When the vehicle's instantaneous speed data is 115 km, it means that the instantaneous speed data minus the road speed limit data is positive (115-100=15) and is above the speed limit buffer value (comparison method such as 15- When 10=5 is positive, 200935367 causes the warning module 150 to output a severe overspeed warning sound. However, the overspeed warning sound, the difference warning sound and the severe overspeed warning sound can be warning sounds, and the difference warning sound and the severe overspeed warning sound further inform the driver of the vehicle that the vehicle exceeds the road speed limit value. ^ In order to effectively know the real-time speed data and the road speed limit data, a display (not shown) can be configured to connect the speed comparison module 140, and the speed comparison module 140 displays the real-time speed data and the road speed limit data on the display. on. The warning module 150 can be a plurality of types of warning devices, and the types of warning sounds or other warning signals are as follows: (1) The warning module 150 can include a buzzer, which outputs a corresponding difference warning sound and serious The sound signal of the speed warning sound. If the corresponding difference warning sounds a short beep, the corresponding severe overspeed warning sounds a long beep. (2) The warning module 150 includes a lighting module (not shown). When the speed comparison module determines that the instantaneous speed data minus the road speed limit data (instant speed data - road speed limit data) is positive In addition to causing the warning module 150 to issue a differential warning sound or a severe overspeed warning sound, the lighting module emits a corresponding warning light. If the corresponding difference warning sound system is a yellow light signal, and the corresponding severe speed warning sound system is a red light signal. (3) The warning module 150 further includes a display module 153, a warning database 151 and a racquet 152. The warning database 151 stores a plurality of warning characters and warning voices. When the comparison speed module 140 determines that the instantaneous speed data of the vehicle reaches the road speed limit, the warning module 150 issues an overspeed warning 200935367. The warning module 150 is for reading 墼 output corresponding speeding warning sound tour=1 illusion and using the heart eight 152 ^ not ^ 曰, while displaying the corresponding overspeed warning "the speeding warning is not in the display module 153. (When comparing the speed module 14〇± the road speed limit but not reaching the severe overspeed, the ^^(4) speed data exceeds the warning value of the road.

Similarly, when the comparison speed module 14 determines that the instantaneous speed data of the vehicle exceeds the level of the road ship and the serious overspeed, the alarm module 15 发出 emits a severe overspeed warning sound. The warning module reads the warning database 151, and uses the racquet 152 to output a warning voice corresponding to the severe overspeed warning sound, and simultaneously displays the severe overspeed warning text corresponding to the severe overspeed warning sound to the display module 153. As shown in FIG. 2 and FIG. 3, when the vehicle 100 travels, the 'speed measuring radar sensor 16' senses the road section limited speed monitoring station 200 of the road of the vehicle 100, and senses the speed limit data of the speed measuring radar 201 of the speed limiting monitoring station 200 and Output to the speed limit correction mode 170. In addition to receiving the speed limit data, the speed limit correction module 170 obtains the road speed limit data of the current road section from the satellite positioning receiving module 110 and determines the road speed limit data according to the speed limit data and the acne speed limit data. The road speed I5 stored in the library 130 is incorrect. If the judgment is no, it will not operate; if it is judged as YES, then according to the speed limit data, the road speed limit database 130 12 200935367, the speed of the road, and the storage of the peaks and materials are the latest.
