FIG. 1 is a schematic view of an apparatus for detecting a liquid level of a sealed fuel tank.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art all belong to the protection scope of the present invention.
As shown in fig. 1, a method for detecting a liquid level of a sealed fuel tank according to an embodiment of the present invention includes:
s100, arranging an ultrasonic liquid level sensor on the outer side wall of a fuel tank, detecting the liquid level in the fuel tank in real time by the ultrasonic liquid level sensor, and respectively sending different signals by the ultrasonic liquid level sensor according to the detected liquid level, wherein the detected liquid level is positioned above or below the ultrasonic liquid level sensor;
s200, transmitting a signal sent by the ultrasonic liquid level sensor to a cloud server;
and S300, reading data on the cloud server by the fuel cell remote data monitoring system.
In a specific embodiment of the present invention, in step S100, the ultrasonic liquid level sensor is located according to the detected liquid level, the signals respectively sent from the top or the bottom of the ultrasonic liquid level sensor specifically include:
when the liquid level is higher than the position of the ultrasonic liquid level sensor, the ultrasonic liquid level sensor sends a high level signal, and when the liquid level is lower than the position of the ultrasonic liquid level sensor, the ultrasonic liquid level sensor sends a low level signal.
In a specific embodiment of the present invention, in step S200, the ultrasonic liquid level sensor sends a signal to the cloud server through the GPRS device.
In a specific embodiment of the present invention, the ultrasonic liquid level sensor is connected to the GPRS device through a serial gateway.
In one embodiment of the present invention, the ultrasonic level sensor is attached to the outer sidewall of the fuel tank at a distance from the tank bottom 1/5.
The utility model provides a detect equipment of liquid level of sealed fuel barrel, includes the fuel barrel, be provided with ultrasonic wave level sensor on the fuel barrel, ultrasonic wave level sensor is connected with serial ports gateway, and serial ports gateway is connected with GPRS equipment, GPRS equipment is connected with cloud ware.
In one embodiment of the present invention, the ultrasonic level sensor is disposed at 1/5 barrel height of the outer side wall of the fuel barrel.
