A remote control (not shown) that is communicatively coupled to the controller. Therefore, a user can remotely control the controller and switch between an automatic mode and a manual mode through the remote controller.

The above is merely an example of the preferred embodiments of the present invention, and the embodiments and the protection scope of the present invention are not limited thereby.

Further, in a preferred embodiment, the route tracker may automatically detect a guidance tape disposed on the ground, so as to perform routing inspection following the guidance tape.

Further, in a preferred embodiment, two hydrogen concentration detecting devices 611 are respectively disposed on the front and rear sides of the hydrogen concentration detecting module 61, and two hydrogen flame detecting devices 621 are respectively disposed on the front and rear sides of the hydrogen flame detecting module 62.

Further, in a preferred embodiment, the hydrogen concentration detection device may be any one of electrochemical, electrical, thermal or optical.

The thermal mode is typically a catalytic combustion type sensor, hydrogen and oxygen are easy to combust under the condition of a catalyst, so that a test element generates heat, and the hydrogen concentration can be calculated according to the heat exchange quantity. In the other thermal hydrogen sensor, no catalyst is used, but the temperature of the micro-electromechanical test element is set to a temperature at which the reaction with hydrogen is easy to occur during the test, so that when hydrogen with high thermal conductivity deprives the element of heat, the temperature of the element is lowered. After the temperature of the element is reduced, the micro-heater is used for heating, and the temperature is restored to the set temperature, so that the hydrogen leakage amount is detected according to the temperature consumption point flow.

The electrochemical hydrogen sensor can realize the rapid detection of hydrogen concentration in the range of 0-104 ppm by using a platinum catalytic electrode prepared by a sputtering coating method, the response time of the sensor is 30s, and the sensitivity is 4 muA/100 ppm. The normal operating temperature range of the amperometric sensor is from-20 ℃ to 80 ℃. Like the hydrogen fuel cell, temperature, pressure and humidity changes have a large influence on the measurement results. Amperometric hydrogen sensors have higher sensitivity at lower hydrogen concentrations, but have too long a response time.

The electrical type is divided into two types of resistor and field effect tube, the structure is simple, the defect is that the temperature required by the work is higher, electric sparks are easy to generate during the work, and the stability is poorer; the resistivity of the resistance-type hydrogen sensor is significantly increased when the semiconductor metal oxide adsorbs oxygen, and is decreased when reducing gases such as hydrogen reduce oxygen in the metal oxide chemisorption layer. Tin oxide as a sensitive material has an average response time of 4s to 20s, and the hydrogen concentration can be measured in the range of 10ppm to 20 ppm. The single metal oxide has low selectivity to hydrogen, is easily interfered by methane, carbon monoxide, alcohols and the like, and can be doped with palladium, platinum and the like for improving the selectivity. A non-resistance type hydrogen sensor deposits a layer of very thin metal on a semiconductor to form a Schottky junction, hydrogen is adsorbed on the surface of the metal with catalytic performance when contacting the Schottky junction, is catalytically decomposed into H, is diffused to a metal semiconductor interface through a metal lattice gap, is added with bias voltage, and the characteristic curve of a semiconductor diode drifts due to the existence of the H, so that the sensor detects the hydrogen concentration by detecting the change of voltage or capacitance.

The optical fiber core of the optical Fiber Bragg Grating (FBG) hydrogen sensor FBG hydrogen sensor mainly comprises the Bragg grating which is periodically arranged, so that the refractive index can be periodically modulated, and light with a specific wavelength can be reflected. When the optical fiber core is plated with the palladium film, if hydrogen is contained in the gas to be detected, the hydrogen permeates into the palladium film, and the generated PdHx enables the volume of the palladium film to expand, so that the grating pitch of the grating is enlarged, and the central wavelength of the reflected light of the grating is changed. By measuring the change of the central wavelength of the grating reflected light, the hydrogen concentration can be measured.

Further, in a preferred embodiment, the hydrogen flame detection device is a photosensitive fire detector, an ultraviolet detector sensitive to shorter wavelength optical radiation, and an infrared detector sensitive to longer wavelength optical radiation. Thereby sensing the occurrence of a flame.

Further, in a preferred embodiment, distance sensing devices are respectively arranged on the front side, the rear side, the left side and the right side of the electric vehicle.

Further, in a preferred embodiment, the electric vehicle is provided with an audible alarm and a light alarm.

In addition to the above embodiments, the present invention also has the following working method:

firstly, a user can switch to an automatic mode through a remote controller; in the automatic mode, the electric vehicle can track along a preset guide belt, namely reciprocate along a preset route; meanwhile, the rotating motor works to enable the rotating platform 11 to rotate 360 degrees, so that the surrounding environment is detected through the camera device 3, the hydrogen flame detection device 621 and the hydrogen concentration detection device 611; when the hydrogen concentration is found to exceed the preset value, if the hydrogen concentration exceeds 4%, the controller is connected with the sound alarm and the light alarm to give an alarm, or when flame is found to be burnt, the controller is connected with the sound alarm and the light alarm to give an alarm.

In addition, owing to set up apart from the inductor, when the object is close to the electric motor car and apart from the object when being less than 0.7m, the electric motor car stops to advance and sends the chimes of doom, when the object is less than 0.5m apart from the electric motor car, the dolly is automatic to be backward patrolled and examined. When the distance between the object and the electric vehicle is greater than 0.7m, the alarm is automatically released.

The above is only a preferred embodiment of the present invention, and not intended to limit the scope of the invention, and it should be appreciated by those skilled in the art that various equivalent substitutions and obvious changes made in the specification and drawings should be included within the scope of the present invention.
