Specifically, in the present embodiment, the MEMS mass flow meter 020 is further integrated with a wireless signal transmitter, which is enabled or disabled by a microcontroller of the MEMS mass flow meter 020, and the wireless signal transmitter is used for transmitting various collected data to a user terminal.
The intelligent industrial gas cylinder management system provided by the embodiment enables a user to remotely know information such as the opening and closing states, the gas flow and the residual gas quantity of the gas cylinder and the valve, is convenient for the user to timely and accurately perform related operations, is high in efficiency, and can effectively avoid waste.
Specifically, as shown in fig. 5, in the intelligent industrial gas cylinder management system provided in this embodiment, a plurality of gas cylinders are connected in series, an intelligent industrial gas cylinder valve 010 is connected in series with a gas pipe or a gas transmission pipeline 030, an inlet of an MEMS mass flow meter 020 integrated with a radio frequency signal reader and a wireless data transmitter is connected to the last gas cylinder in the series, and an outlet is connected to the gas transmission pipeline 030.

The information may be transmitted through various remote data transmission methods or Internet of Things (IoT) protocols.

In this arrangement, the MEMS mass flow meter 020 can interact with a local router or a web site.

In summary, for the gas cylinder installed with the above-mentioned intelligent industrial gas cylinder management system, no matter the intelligent industrial gas cylinder valve 010 is engaged with the existing mechanical valve handle or is directly installed on the valve rod, the working process is approximately:
initially, before the valve is opened, the rf code on the rf tag 210 is blocked by the handwheel 100 and the display window 120 does not display any information.
When the handwheel 100 of the intelligent industrial gas cylinder valve 010 is turned to the open position, the display window 120 displays the open radio frequency code and the serial number, and the type or the composition of the gas in the gas cylinder and other related information. The MEMS mass flow meter begins measuring the instantaneous flow rate of the gas and the total consumption of the gas and subsequently wakes up a radio frequency signal reader integrated within the mass flow meter. The rf signal reader will acquire data from the smart industrial cylinder valve 010. After data acquisition is completed, a microcontroller in the mass flow meter wakes up a wireless data transmitter, and the acquired data is transmitted to a designated data center or data cloud for further data processing by using methods such as LoRa (Long Range Radio), NB IoT (Narrow Band Internet of Things), GSM (Global System for Mobile Communications ), Sigfox (Sigfox constructs a wireless network dedicated to Internet of Things devices by Ultra Narrow Band (umb) technology), WIFI, or other required data transmission methods. Preferably, if the entire system is battery powered, the radio frequency signal reader and wireless data transmitter will then be disabled.
When the handwheel 100 of the smart industrial cylinder valve 010 is turned to the closed position, the display window 120 displays the closing radio frequency code, and the opening radio frequency code will be hidden by the handwheel 100. Meanwhile, the MEMS mass flow meter records zero flow, then wakes up the radio frequency signal reader and the wireless data transmitter to obtain the serial number and the state of the gas cylinder in a closed state, and transmits related information to a designated data center or a data cloud for further data processing.
Of course, the user may also preset other critical information such as gas consumption alarms, which may be preprogrammed or set in the MEMS mass flow meter. For example, when the gas consumption of a particular or multiple cylinders measured by the mass flow meter matches a preset alarm value, a microcontroller within the mass flow meter will wake up the wireless data transmitter and relay the data to a designated data center or data cloud for further data processing.
