Vehicle safety warning system

The invention relates to a vehicle safety warning system, in particular to a vehicle safety warning system capable of providing vehicle status information.

Since the combustion of petrochemical energy pollutes the environment, vehicles that reduce the dependence on petrochemical energy or improve the efficiency of fuel use, such as oil-hydrogen hybrid vehicles, are used to perform electrolysis to generate hydrogen. The hydrogen is sent to the engine's cylinders and mixed with fuel to burn to generate power. The flammability of hydrogen can increase the combustion efficiency of fuel, improve energy efficiency, and reduce air pollution. This oil-hydrogen hybrid drive engine can be installed on the locomotive in addition to the car. Since hydrogen is flammable, and there is usually a spark generated when the locomotive is dumped, and there is a danger of igniting hydrogen, the current hydrogen-hydrogen hybrid vehicle has the disadvantage of insufficient safety.

On the other hand, in addition to the start of the vehicle, the battery is also supplied with an electrolytic reaction. Therefore, the battery may be supplied with an electrolytic reaction, and the electric quantity is lower than the starting voltage of the vehicle, which may cause the vehicle to fail to start and malfunction. In addition, if the battery is discharged too deeply, it will also reduce its service life. Therefore, a general hydrogen-oil hybrid vehicle also has a situation in which it is easy to malfunction and the battery life is short.

Accordingly, it is an object of the present invention to provide a vehicle safety alert system that improves safety and avoids malfunction.

Thus, the vehicle safety warning system of the present invention can be installed on a vehicle that uses a battery to drive an electrolysis device for electrolysis to generate hydrogen gas, and uses hydrogen as one of the power sources. The vehicle safety system includes: a battery measuring device electrically connected to the battery, an electrolytic monitoring device, a signal processor electrically connected to the battery measuring device and the electrolytic monitoring device, a display device electrically connected to the signal processor, and an electrolytic switching device . The battery measuring device can measure the amount of electricity of the battery, and the electrolytic monitoring device can measure the amount of hydrogen generated by the electrolytic device. The display device can display the amount of electricity of the battery and the amount of hydrogen generated by the electrolyzer. The electrolysis switching device can be activated or interrupted by the signal processor to perform an electrolysis reaction of the electrolysis device.

The beneficial effect of the invention is that the battery measuring device, the electrolytic monitoring device and the electrolytic switching device are connected to the signal processor, and when the battery voltage is too low, the electrolysis can be interrupted, and the voltage is maintained at the start of the vehicle. Above the voltage, the vehicle can be restarted after the flameout, to avoid malfunction.

The above and other technical contents, features and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments of the invention. It is to be noted that in the following description, like elements are denoted by the same reference numerals.

Referring to Figure 1, a first preferred embodiment of the vehicle safety warning system 1 of the present invention is mounted on a hydrogen-hydrogen hybrid powered vehicle (not shown) that includes a battery 2 and a battery that can be used by the battery. An electrolysis device 3 that generates an electrolysis reaction to generate hydrogen gas, and a power generation device (not shown) that can charge the battery 2. The vehicle safety warning system 1 includes: a battery measuring device 11 electrically connected to the battery 2, an electrolytic monitoring device 12 electrically connected to the electrolytic device 3, and an electrolysis electrically connected between the battery 2 and the electrolysis device 3. The switching device 16, a signal processor 13 electrically connected to the battery measuring device 11 and the electrolytic monitoring device 12, a warning device 14 electrically connected to the signal processor 13, and an electrical connection with the signal processor 13 Display device 15.

The signal processor 13 has an input module 131 for receiving signals, an operation module 132 for calculating signals received by the input module 131, and an output module 133 for outputting signals.

The battery measuring device 11 can measure the power of the battery 2, and transmit the measurement result to the input module 131 of the signal processor 13, and then output the signal to the display device 15 by the output module 133, and then The measurement result of the battery measuring device 11, that is, the amount of electricity of the battery 2, is displayed on the display device 15 as a percentage. In the preferred embodiment, the battery measuring device 11 measures the charge and discharge current of the battery 2, and estimates the amount of electricity of the battery 2 by using an ampere hour integration method. The ampere hour integration method calculates the amount of change of the battery 2 by using the current magnitude and the time of charging and discharging to estimate the amount of electricity of the battery 2. However, there are many methods for measuring the electric quantity of the battery 2, for example, it can also be estimated by the electrolytic solution specific gravity method, that is, the specific gravity of the electrolyte in the battery 2 (not shown) is linear with the electric quantity of the battery 2, so it is not The examples are limited.

The electrolysis monitoring device 12 can measure the amount of hydrogen generated by the electrolysis device 3, and transmit the measurement result to the input module 131 of the signal processor 13, and then transmit the signal to the display device 15 by the output module 133. Further, the measurement result of the electrolysis monitoring device 12, that is, the amount of hydrogen generated (g/liter, which is the number of grams of hydrogen gas generated per liter), is displayed on the display device 15. In the preferred embodiment, the electrolysis monitoring device 12 measures the amount of current flowing into the electrolysis device 3 to estimate the amount of hydrogen produced by the electrolysis device 3.

The electrolytic switching device 16 is electrically connected between the battery 2 and the electrolysis device 3, and is driven by the output module 133 to activate or interrupt the electrolysis reaction of the electrolysis device 3. In the preferred embodiment, the electrolytic switching device 16 is a toggle switch and is implemented using a high power MOSFET circuit. The alerting device 14 can be driven by the output module 133 of the signal processor 13 and emit a warning sound. In the preferred embodiment, the alerting device 14 is a buzzer and a flashing light emitting diode. body.

Under normal circumstances, after the battery is started by the battery 2, the battery 2 continues to supply power to the electrolysis device 3 for electrolysis reaction. At this time, the display device 15 displays the residual electric quantity of the battery 2 and the hydrogen production amount of the electrolysis device 3, The computing module 132 continuously monitors and calculates the signal received by the input module 131. When the battery 2 is lower than the lower limit, the computing module 132 drives the output module 133 to output a signal. The electrolysis switching device 16 causes the electrolysis switching device 16 to interrupt the electrolysis reaction of the electrolysis device 3, and the output module 133 also outputs a signal to drive the warning device 14 to emit a warning sound to remind the driver that the battery 2 is too low. In this way, the vehicle can be prevented from being unable to be started due to the low battery level of the battery 2, and in addition, the battery 2 can be prevented from aging due to excessive discharge. Therefore, the present invention has the advantages of avoiding the occurrence of malfunction and prolonging the service life of the battery 2.

When the electrolysis switching device 16 interrupts the electrolysis reaction, the power generating device (not shown) charges the battery 2 during the running of the automobile, and switches the electrolysis after the electric quantity of the battery 2 is greater than an electrolysis value. The switching device 16 causes the electrolysis device 3 to perform an electrolytic reaction again. In the preferred embodiment, the lower limit is about 10.5 volts, and the size of the lower limit is the starting voltage required for different vehicles, and thus is not limited thereto. In addition, the electrolytic value of the present embodiment is about 24 volts, and is not limited thereto. As long as the electrolytic reaction is restarted, the battery 2 can supply sufficient voltage to start the vehicle.

The signal processor 13 mainly performs basic comparison operations, buffering, and temporary storage functions. In the preferred embodiment, the model is implemented by using a DSP TMS320F2812 chip. However, it is not limited thereto. A wafer that can perform comparison operations and has basic buffering and temporary memory functions.

It is further noted that the display device 15 of the present embodiment is a liquid crystal display, which can indicate whether the reaction of the electrolysis device 3 is electrolyzed, and the amount of hydrogen produced, and can also display the current percentage of available electricity of the battery 2, and warn of hydrogen production. Or the battery 2 is abnormally charged, thereby warning the driver and allowing the driver to fully grasp the state of the car. In addition, the driver can also track the amount of hydrogen produced to determine the degree of aging of the electrolyzer 3, and then replace it in advance.

Referring to FIG. 2, a second preferred embodiment of the vehicle safety warning system 1 of the present invention is mounted on a locomotive (not shown) of a hydrogen-hydrogen hybrid drive, and the preferred embodiment and the first preferred embodiment The difference in the embodiment is that the vehicle safety warning system 1 of the preferred embodiment further includes a vehicle position measuring device 17 electrically connected to the signal processor 13. The attitude measuring device 17 can measure the tilt angle of the locomotive (not shown) and transmit the measurement result to the input module 131 of the signal processor 13, and then the output module 133 transmits a signal to the display. The device 15 further displays the measurement result of the vehicle attitude measuring device 17, that is, the angle at which the locomotive is tilted, on the display device 15. The angle at which the locomotive is tilted refers to the angle between the locomotive and the lead line. In addition, the computing module 132 drives the output module 133 to output the signal to the electrolytic switching device 16 when the angle at which the locomotive is tilted is greater than a tilting angle, and causes the electrolytic switching device 16 to interrupt the electrolytic reaction of the electrolytic device 3. At the same time, the output module 133 also outputs a signal to drive the warning device 14 to emit a warning sound to warn the driver that the locomotive has a risk of falling over. The tilting angle of the embodiment is 40 degrees, and since the general locomotive swings between a slight angle to maintain balance, the tilting angle is too small, and the electrolysis reaction cannot be operated normally because the acuity is too high. When the tilting angle is too large, the system cannot issue a warning during the user's reaction time, and the safety effect is reduced, so the range of the tilting angle is optimal between 30 degrees and 45 degrees. The posture measuring device 17 of the present embodiment uses a gyroscope to detect the tilting angle. It can be seen from the above description that the present invention can avoid the leakage of combustible hydrogen gas, and can avoid the spark generated by the vehicle when the vehicle is dumped, and thus has the advantages of improving driving safety.

The above is only the preferred embodiment of the present invention, and the scope of the invention is not limited thereto, that is, the simple equivalent changes and modifications made by the scope of the invention and the description of the invention are All remain within the scope of the invention patent.
