[0042] Used to detect the pressure inside the gas tank. The output signal of the pressure sensor is connected to the signal isolator (AI01-3, AI01-4), and the signal is transmitted to the PLC through the isolator.

[0043] Signal isolators (AI01-1, AI01-2, AI01-3, AI01-4) are used to isolate and process sensor signals, reduce electromagnetic interference, and ensure stable signal transmission.

[0044] The PLC is responsible for receiving the data transmitted by the signal isolator, processing and monitoring the status of the gas tank in real time. The user can preset the threshold in the PLC so that when it detects abnormal tilt or pressure, it triggers an alarm and outputs an alarm control signal through the IO port of the device.

[0045] In this embodiment, a signal isolator is added to each sensor, and a fuse is used to protect the power supply of the signal isolator, which greatly reduces the crosstalk problem between sensor channels and greatly improves the overall reliability of the system.

[0048] The main power interface is connected to the main 220VAC power supply, and the backup power interface is connected to the backup 220VAC power supply;

[0049] The main power interface is connected to the L input terminal and the N input terminal of the voltage regulator module PM11, and the positive output terminal and the negative output terminal of the voltage regulator module PM11 are respectively connected to the IN24V-1 terminal and the GND terminal of the power switch 1PR1;

[0050] The IN+ and IN- terminals of UPS module UPS1 are connected to circuit breaker 01QF00, the BAT+ and BAT- terminals of UPS module UPS1 are connected to the external battery pack, and the OUT+ and OUT- terminals output 24VDC power supply, the 13th, 23rd and 33rd pins of UPS module UPS1 are connected to the OUT+ pin of UPS module UPS1, and the 14th, 24th and 34th pins of UPS module UPS1 are respectively connected to different IO ports of PLC;

[0051] The backup power interface is connected to the L input terminal and the N input terminal of the voltage regulator module PM12, and the positive output terminal and the negative output terminal of the voltage regulator module PM12 are respectively connected to the IN24V-2 terminal and the GND terminal of the power switch 1PR1;

[0052] The OUT24V and GND terminals of the power switch 1PR1 are both connected to the circuit breaker 01QF00;

[0053] The grounding terminal of the voltage stabilizing module PM11 and the grounding terminal of the voltage stabilizing module PM12 are both connected to the earth PE.

[0054] The models of the voltage stabilizing module PM11 and the voltage stabilizing module PM12 are both 6EP1336-3BA10, the model of the UPS module UPS1 is QUINT-UPS / 24DC / 24DC / 20, the model of the power switch 1PR1 is 6EP1961-3BA21, and the model of the circuit breaker 01QF00 is A9N18232.

[0055] The models of the isolator AI01-1, the isolator AI01-2, the isolator AI01-3 and the isolator AI01-4 are all DGG-8130.

[0056] In this embodiment, the power switch 1PR1, the voltage stabilizing module PM11 and the voltage stabilizing module PM12 together constitute the high-voltage circuit part of the power supply part, while the UPS module UPS1 supplies power to the weak parts such as the PLC. During this period, the protection isolation of the high-voltage circuit part and the weak-voltage circuit part is achieved through the circuit breaker 01QF00, which well protects the power supply safety of the subsequent circuits and modules of the weak parts.

[0057] The voltage stabilizing module PM11 and the voltage stabilizing module PM12 are powered by a main power supply and a backup power supply respectively. The main power supply is a common power supply, which is the mains in this embodiment, and the backup power supply is a generator.

[0058] The principle of the power switching unit is as follows:

[0059] The voltage stabilizer PM11 of the main power supply and the voltage stabilizer PM12 of the backup power supply are connected to the main power supply interface and the backup power supply interface respectively to convert the input 220VAC power supply into 24VDC power supply. The power switching module 1PR1 receives the output of the main power supply and the backup power supply, and automatically switches to the backup power supply according to the status of the main power supply to ensure the continuity of power supply. The UPS module UPS1 is connected to the output end of the power switching module to provide an uninterruptible power supply of 24VDC to ensure that the system can still operate when the main power supply and the backup power supply fail at the same time, and to prevent the idle fluctuations that may occur during the switching process.

[0060] The power switch 1PR1 can automatically switch between the main power supply and the backup power supply. Since the power switch 1PR1 adopts 6EP1961-3BA21, this module is usually used in industrial automation systems to ensure that uninterrupted power supply can continue to be provided when the main power supply fails. There will be a very short time interval (usually millisecond level) when it is switched. This time interval may affect the collection of the tilt angle, causing the collected data to fluctuate, and in severe cases, misjudgment and false alarm may occur. Therefore, in this embodiment, UPS is used as a redundant design, and a UPS power supply is added behind the circuit breaker 01QF00 to stabilize the 24VDC direct current power supply. This not only solves the problem of idle time when switching the power supply, but also makes the power supply more stable and improves the stability of the tilt angle.

[0061] This embodiment is also provided with two pressure sensor channels, which can be used to detect the gas pressure of the gas tank to ensure safe use.

[0062] The gas tank tilt detection device system described in the utility model solves the technical problems of improving the isolation between sensors, improving environmental adaptability, and unstable power supply. The utility model adopts a redundant design of the main power supply, the backup power supply and the UPS power supply to ensure that the system can continue to operate in any power failure situation, thereby improving the reliability of the system and eliminating the phenomenon of instantaneous idle time when switching from the main power supply to the backup power supply. The standardized industrial module design is adopted to facilitate the expansion and maintenance of the system, can adapt to harsh environments, reduce electromagnetic interference through signal isolators, improve the reliability of signal transmission, and ensure the stable operation of the system.
