Problems solved by technology

1. Use the wheel speed or mileage sensor signal to count pulses, and multiply it by the tire circumference to get the vehicle speed. The wiring of this scheme is complicated, and the parameters set for different tires are different. At the same time, the chassis circuit needs to be changed, which is prone to failure
2. Using GPS or Beidou satellite navigation signals to obtain vehicle speed, this solution has shortcomings such as signal drift, no signal when tunnel

Embodiment Construction

[0009] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0010] exist figure 1 Among them, one end of the input module 3 is connected with the air pressure switch 1 and the electronic gyroscope module 2, the other end of the input module 3 is connected with the single-chip microcomputer module 5, and the other end of the single-chip microcomputer module 5 is respectively connected with the power supply 4 and the output module 6, and the output module 6 is separately One end is connected with the solenoid valve 7 and the sound and light alarm module 8 .

[0011] First judge the working state of the emergency shut-off valve. When it is in the open state, the air pressure switch 1 sends a signal to the single-chip microcomputer 5 through the input module 3; the single-chip microcomputer control circuit starts to supply power to the electronic gyroscope module 2, and the electronic gyroscope 2 collects the XYZ th...

Abstract

The invention relates to the field of tank type dangerous goods-transportation vehicles, in particular to an emergency cut-off valve automatic closing device based on an electronic gyroscope. The emergency cut-off valve automatic closing device based on the electronic gyroscope is characterized in that one end of an input module is connected with an air pressure switch and an electronic gyroscopemodule, the other end of the input module is connected with one end of a microcontroller module, the other end of the microcontroller module is connected with a power supply and one end of an output module, and the other end of the output module is connected with an electromagnetic valve and a sound-light alarm module. Through the adoption of the technical scheme, the structure of the device is simple, and the purpose of judging the working state of the emergency cut-off valve and the purpose of automatically turning off the cut-off valve or giving an alarm can be achieved.

Description

technical field [0001] The invention relates to the field of tank-type dangerous goods transport vehicles, and relates to an automatic closing device for an emergency cut-off valve based on an electronic gyroscope. Background technique [0002] According to the requirements of the GB7258-2017 standard, the design and manufacture of tank-type dangerous goods transport vehicles equipped with emergency shut-off devices should ensure that the emergency shut-off valve can be automatically closed when the speed of the vehicle transporting liquid dangerous goods is greater than 5km / h, or when the engine When starting, an obvious signal device can be used to prompt the driver to close the emergency shut-off valve. [0003] The technical difficulty in realizing this function lies in the collection and judgment of vehicle speed. There are various shortcomings in other schemes at present. 1. Use the wheel speed or mileage sensor signal to count the pulses, and multiply the tire circu...
