Embodiment 1

[0024] The embodiment of the remote automatic control system of the present invention is basically as attached figure 1 As shown, including the detection module, judgment module, alarm module, remote module and cloud camera, where the cloud camera is not in figure 1 drawn in.

[0025] The detection module includes two Risym 16MM ultrasonic sensors (transceivers), MDT2030S microcontroller, VMS-300C3-WS-GPRS temperature sensor, BMP280-3.3 pressure sensor and DSP56301PW80 DSP processor. The positions of the two ultrasonic sensors are fixed, and the distance between them is L. One of the ultrasonic sensors sends a pulse signal to the other ultrasonic sensor, and when the ultrasonic wave is emitted, the single-chip microcomputer is started to count immediately. When the single-chip microcomputer detects that the amplitude of the received signal exceeds the reference threshold, it stops counting immediately. At this time, the count value N can be read from the microcontroller. A...

Embodiment 2

[0057] The only difference from Embodiment 1 is that a high-definition cloud camera is also installed at the gas filling station, and the cloud camera is connected to the server of the remote module through a wireless network. When the concentration of natural gas in the air is greater than the lower limit of explosive concentration, the power trigger mechanism of the cloud camera will be powered on, and then the cloud camera will start to shoot video in the gas filling station, and send the captured video to the display screen of the remote module. This is convenient for the staff to observe the actual situation in the filling station in real time.

Embodiment 3

[0059] The only difference from Example 2 is:

[0060] as attached figure 2 As shown, it also includes a gas filling pipe 1, a valve 2, a motor 31 and a motor bracket 32. The valve 2 is made up of a valve knob 21 , a valve flap 22 and a valve shaft 23 , and the valve knob 21 and the valve flap 22 are welded on the valve shaft 23 . The installation direction of the valve rotating shaft 23 is perpendicular to the axial direction of the gas filling pipe 1 , and the valve disc 22 is installed in the gas filling pipe 1 . The valve flap 22 is circular in shape, and its radius is equal to the inner diameter of the gas filling pipe 1 . The motor bracket 32 ​​is welded on the outer wall surface of the gas filling pipe 1, and the motor 31 is installed on the motor bracket 32; the motor 31 is installed vertically with the valve shaft 23, and can drive the valve shaft 23 to rotate (for detailed installation steps of the motor, please refer to the prior art) . When the valve knob 21 i...

Abstract

The invention relates to the technical field of fuel gas remote monitoring, and particularly relates to a remote automatic control system. The remote automatic control system comprises a detection module, a judgment module, an alarm module, a cloud camera and a remote module, wherein the detection module is used for detecting the concentration of natural gas in the air through an ultrasonic technology; the judgment module is used for judging whether the detected concentration of the natural gas in the air is greater than a lower limit of the explosion concentration or not; the alarm module isused for giving an alarm when the concentration of the natural gas in the air is greater than the lower limit of the explosion concentration and sending alarm information to the remote module; the cloud camera is used for starting to shoot a video when the concentration of the natural gas in the air is greater than the lower limit of the explosion concentration and sending the shot video to the remote module; and the remote module is used for monitoring a gas station in real time. According to the invention, the concentration, which is calculated through the supersonic speed technology, of thenatural gas in the air is high in precision and small in error, and accurate alarm data can be provided.

Description

technical field [0001] The invention relates to the technical field of gas remote monitoring, in particular to a remote automatic control system. Background technique [0002] A natural gas filling station refers to a place that provides fuel to natural gas vehicles in the form of compressed natural gas. Even an ordinary small natural gas filling station has a capacity of tens of tons. The main component of natural gas is methane, which has low ignition point, high calorific value, and low explosion concentration limit. When natural gas leaks and encounters an open flame, it is very easy to explode. Therefore, it is particularly important to detect the concentration of natural gas in the gas filling station in real time and to give an alarm when the concentration exceeds the threshold. [0003] Document CN102426220B discloses a gas concentration detection method and a mobile terminal. The gas concentration detection method includes: the mobile terminal detects the gas conce...
