All other embodiments derived by those skilled in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0035] See also Figures 1 to 4The embodiment of the present invention provides a miniaturized wireless pressure detection device, comprising an outer shell 1, a pipeline assembly 2 and a wireless pressure detection module 3;

[0037] Among them, such as Figure 2 and Figure 3 As shown, the wireless pressure detection module 3 includes a circuit board 301 and an air pressure sensor 307 electrically connected to the circuit board 301 , a control chip 305 and a ceramic patch structure antenna 306 .

[0038] It should be noted that the specific working principle of the miniaturized wireless pressure detection device in this embodiment is as follows:

[0039] The pipeline component 2 is connected to the gas storage device 4 to achieve connectivity between the gas storage device 4 and the closed cavity. At this time, the air pressure sensor 307 detects the air pressure of the gas and transmits the sampled data obtained by the detection to the control chip 305. The control chip 305 summarizes, processes and analyzes the sampled data and then wirelessly transmits the collected data to the wireless receiving device of the inspector through the ceramic patch structure antenna 306.

[0040] The above detection process may perform multiple samplings at preset intervals to effectively monitor the gas storage device 4 .

[0041] In addition, the inspector can specifically use a Bluetooth signal receiver remotely, which can be a smart phone or other device with wireless capabilities, to receive the wireless signal emitted by the ceramic patch structure antenna 306, and by screening data that conforms to the data packet format, the air pressure conditions and equipment conditions of all nearby gas storage devices 4 can be counted and detected.

[0042] In the miniaturized wireless pressure detection device of this embodiment, a ceramic patch structure antenna 306 is used as a transmission element. Its small size can significantly reduce the volume of the wireless pressure detection device. In addition, the air pressure sensor 307, the control chip 305 and the ceramic patch structure antenna 306 are all integrated into the circuit board 301 to directly transmit electrical signals between boards. The integrated integrated design can further reduce the size of the wireless pressure detection device, which is conducive to the miniaturization design of the wireless pressure detection device.
