Abstract
The utility model discloses an oil level control device for a dangerous chemical vehicle. The device comprises an oil level sensor and a vehicle-mounted terminal, and also comprises a storage used for storing all oil level signals sent by the oil level sensor in a period of time, and a comparator used for receiving two oil level signals at an interval of 5 to 15 seconds which are stored in the storage and making a comparison. If the difference value of the two oil level signals at an interval of 5 to 15 seconds is smaller than 1%, the comparator transmits the oil level signal at a later time point to the vehicle-mounted terminal. By comparing the difference value of two oil level signals at an interval of 5 to 15 seconds, signals with a difference value of more than 1% in 5 to 15 seconds are filtered, and accuracy of oil level measurement is ensured.
Description
Technical field
The utility model relates to vehicle transport administrative skill field, especially relates to a kind of danger product vehicle borne management system.
Background technology
The dangerization product are abbreviations of hazardous chemical article, and the dangerization product especially should be noted that safety problem when transportation, and before setting out, the management of vehicle transport route so vehicle is even more important.
The vehicle oil consumption management is also the important ring in the management of dangerization product vehicle transport, accurately grasps the oil level in oil tank of vehicle, arranges stroke extremely important for the driver.Fuel level sensor all is housed on traditional vehicle, and fuel level sensor directly passes to car-mounted terminal with the numerical value of the oil level measured.When bumpy sections was arrived in vehicle operating, the oil level in fuel tank was not to be parked in change, can not react the true oil level of fuel tank inner fluid.Therefore be necessary to be changed.
Summary of the invention
The utility model provides a kind of danger car oil level control device for deficiency of the prior art, can be at vehicle Measurement accuracy oil level when bumpy sections is travelled.
For solving the problems of the technologies described above; the utility model is solved by following technical proposals: dangerization car oil level control device; comprise fuel level sensor and car-mounted terminal; also comprise the storer of all oil level signal of sending for described fuel level sensor in storage a period of time and be used for receiving two oil level signal of being separated by 5 to 15 seconds of storing in described storer and the comparer that compares; if the difference of these two oil level signal of being separated by 5 to 15 seconds is less than 1%, the oil level signal after described comparer leans on time point passes to described car-mounted terminal.Vehicle is when normally travelling, be separated by the short period, violent variation can not occur in the oil mass in fuel tank, but vehicle is when travelling in the highway section of jolting, fluid in fuel tank is ceaselessly rocking, and this also causes the oil level numerical value that fuel level sensor measures ceaselessly to change.According to this principle, if differing, two oil level signal of being separated by 5 to 15 seconds surpass 1%, fluid is described also in rocking, the oil level signal that this moment, fuel level sensor measured can not reflect the amount of real fluid in fuel tank.If two oil level signal of being separated by 5 to 15 seconds differ less than 1%, illustrate that the fluid in fuel tank does not occur obviously to rock, at this moment the data that measure of fuel level sensor are accurately, data only in this way just pass to car-mounted terminal and show oil level.Can filter out like this vehicle inaccurate oil level signal when bumpy sections is travelled, guarantee the accuracy of oil-level measurement.
In technique scheme, preferred, described fuel level sensor comprises a sounding rod, described sounding rod hollow, and the bottom of described sounding rod is provided with oil supply hole, and the top of described sounding rod is provided with vent port.
In technique scheme, preferred, be fixed with a mounting disc on described sounding rod, be provided with through hole in described mounting disc.
In technique scheme, preferred, be fixed with electric storehouse in described mounting disc.
The beneficial effects of the utility model are: by the difference of two oil level signal in 5 to 15 seconds of relatively being separated by, filter out those and differed in 5 to 15 seconds and surpass 1% signal, guarantee the accuracy of oil-level measurement.
Description of drawings

Embodiment
below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail: referring to Fig. 1, dangerization car oil level control device, comprise fuel level sensor 1 and car-mounted terminal 2, also comprise for the storer 3 of storing all oil level signal that in a period of time, described fuel level sensor 1 sends with for two oil level signal of the 10 second time of being separated by that receives described storer 3 interior storages and the comparer 4 that compares, if the difference of these two oil level signal of being separated by 10 seconds is less than 1%, oil level signal after described comparer 4 leans on time point passes to described car-mounted terminal 2.
Referring to Fig. 2 and Fig. 3, described fuel level sensor 1 comprises a sounding rod 11, described sounding rod 11 hollows, and the bottom of described sounding rod 11 forms oil supply hole 12, and the top of described sounding rod 11 forms vent port 13.Be fixed with a mounting disc 14 on described sounding rod 11, be provided with through hole 15 in described mounting disc 14.
Be fixed with electric storehouse 16 in described mounting disc 15, be provided with change-over circuit in electrical store 16.Transmission line 17 is drawn in electric storehouse 16, is connected with storer 17, and the data that fuel level sensor 1 is measured send to storer 17 temporarily to store.
Referring to Fig. 4, when fuel level sensor 1 was arranged on fuel tank 5, sounding rod 11 stretched in fuel tank 5, and mounting disc 14 is close to the outer wall of fuel tank 5, the through hole 15 that bolt 6 passes in mounting disc 14 is connected on the shell of fuel tank 5 later, realizes the fixing of fuel level sensor 1 and fuel tank 5.Fluid in fuel tank 5 enters in sounding rod 11 by the oil supply hole 12 of bottom, and when fluid entered, the air in sounding rod 11 was discharged from vent port 13.
