[0027] like Figures 1 to 4 As shown, the present embodiment provides an embedded solar-powered wireless instrument, which is a pressure sensing instrument, including a base 13, the front end of the base is connected to a front cover 1, the rear end of the base is connected to a rear cover 25, the bottom of the base is connected to a pressure sensor 23 for detecting pressure signals in oilfield pipelines, the side of the base is connected to an antenna 11, and the connection between the antenna 11 and the base 13 is sealed by an O-ring 12.

[0028] The base 13 is provided with a display panel 7 and an instrument circuit board 15. The instrument circuit board 15 is equipped with a pressure signal conversion circuit and a wireless transceiver module. The input of the pressure signal conversion circuit is connected to the pressure sensor 23, converting the pressure signal collected by the pressure sensor 23 into a signal recognizable by the display panel 7 and the wireless transceiver module. The output of the pressure signal conversion circuit is connected to the display panel 7 and the wireless transceiver module, respectively. The display panel 7 is used to display the pressure value, and the wireless transceiver module is connected to the antenna 11 to wirelessly transmit the pressure signal to the server in the central control room. In this embodiment, the display panel 7 is a liquid crystal display. To meet explosion-proof requirements and protect the LCD, the outer surface of the LCD is covered with a front cover glass 3. The front cover 1 has a hollow structure that exposes the display panel. The front cover 1 and the front cover glass 3 are sealed by an O-ring 2. In other embodiments, the front cover 1 and the front cover glass 3 can also be made into an integrated structure, as long as there is a light-transmitting surface so that the content displayed on the display panel 7 can be viewed from the outside of the instrument. Furthermore, in order to prevent wear between the front cover glass 3 and the display panel 7 , a sealing flat gasket and a pressure ring 5 are sequentially arranged between the front cover glass 3 and the display panel 7 .

[0029] The pressure sensor 23 may also be replaced by other signal acquisition sensors, such as a flow sensor, etc., and correspondingly, the pressure signal conversion circuit is also replaced by a corresponding sensor signal conversion circuit.

[0030] The base 13 is also provided with an embedded solar panel 17 and a rechargeable battery pack 16. The solar panel 17 is electrically connected to the rechargeable battery pack 16 for charging through a voltage stabilizing circuit located on the instrument circuit board 15. The light-receiving surface of the solar panel 17 faces the outside of the instrument and is isolated from the outside of the instrument by an explosion-proof light-transmitting plate 18.

[0031] The solar panel 17 is the same size as the explosion-proof light-transmitting panel and is embedded in the substrate. In this embodiment, the solar panel 17 is a monocrystalline silicon solar panel with a size of φ100 and a specification of 5.2V. Its main function is to supply power to the rechargeable battery pack 16. A higher voltage is selected to ensure that it can be charged in the presence of light.

[0032] The power generated by the solar panel 17 is unstable. A voltage stabilization circuit controls the charging voltage at approximately 3.7V to protect the rechargeable battery pack 16. In this embodiment, the rechargeable battery pack 16 uses four 2600mAH 18650 lithium batteries connected in parallel, forming a lithium battery pack with a rated capacity of 11200mAH. This ensures that the wireless instrument can operate normally and continuously for approximately 30 days in complete darkness.

[0033] The rear cover 25 has a hollow structure, allowing sunlight to pass through the explosion-proof light-transmitting plate 18 and illuminate the light-receiving surface. In this embodiment, the rear cover 25 and explosion-proof light-transmitting plate 18 are separate structures, and the connection between the rear cover 25 and the explosion-proof light-transmitting plate 18 is sealed by a sealing flat gasket 24. The explosion-proof light-transmitting plate 18 is explosion-proof transparent glass. In certain embodiments, the rear cover 25 and explosion-proof light-transmitting plate 18 can also be an integral explosion-proof transparent glass cover plate, requiring only that the explosion-proof transparent glass cover plate be sealed to the base 13.

[0034] In this embodiment, the instrument circuit board 15 and display panel 7 are fixedly connected to the inner cavity of the base 13 by screws 6, bolts 9 and / or studs 14. A gasket 8 is provided behind the screws 6. The components are sealed by O-rings 2, 10, 12, and 21.

[0035] Furthermore, the instrument of this embodiment has a waterproof function. A through hole is provided on the base 13. After high-pressure gas is injected into the through hole, it is sealed through the rubber plug 19, the flat washer 20 and the compression nut in sequence.

[0036] In some embodiments, the signal may be transmitted in a wired manner, without the antenna, and the device may be directly connected to the external device via a cable.

[0037] As a second aspect of this embodiment, Figure 5 As shown, this embodiment also provides an oilfield information collection system, comprising a data processor and several embedded solar-powered wireless meters. The embedded solar-powered wireless meters are deployed on oilfield pipelines and wirelessly connected to the data processor. The data processor is located in a central control room and serves as a server. The embedded solar-powered wireless meters have IDs, which are used to determine the location of the meters.

[0038] When the embedded solar-powered wireless instrument is a pressure sensor, the oilfield information collection system collects pressure signals from various locations on the oil pipeline. When the embedded solar-powered wireless instrument is a flow sensor, the oilfield information collection system collects flow signals from various locations on the oil pipeline. Alternatively, the embedded solar-powered wireless instrument can be both a pressure sensor and a flow sensor, allowing the oilfield information collection system to collect both pressure and flow signals simultaneously.

[0039] In this embodiment, the wireless transceiver module is a Zigbee communication module, operating in intermittent mode and consuming power in the microampere (µA) range. Other wireless communication modules can also be used. When the transmission distance is too long or there are obstacles blocking the signal, signal relay equipment can be used to relay the signal. This is a conventional technical approach and will not be repeated here.

[0040] Among them, the precautions for installing solar panels are as follows:

[0041] 1. Customize the same buckle type with explosion-proof glass back cover. To meet the explosion-proof standards, customize the same size circular monocrystalline silicon solar panel according to the inner diameter of the explosion-proof glass, with a maximum output voltage of +5.2V (can be charged in the presence of light).

[0042] 2. Connect four 2600mAH rechargeable batteries in parallel to form a lithium battery pack with a rated capacity of 11200mAH, a built-in charging voltage regulation protection circuit, and an operating voltage of 3.7V.

[0043] 3. Extend two φ3*6 screws from the battery fixing screws inside the instrument.

[0044] 4. Press Figure 4 The charging schematic diagram shows the internal circuit connections.

[0045] 5. After the internal battery pack, solar panel and circuit are connected correctly, cover the back cover with explosion-proof glass 25.

[0046] This utility model can be retrofitted into existing wireless meters. Its built-in solar panel ensures that light energy is collected without damaging the panel. The meter is also more compact than external models, making it easier to operate and inspect. The optimized solar power supply extends the instrument's service life, ensuring long-term, continuous, and efficient operation.

[0047] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all such improvements and changes should fall within the scope of protection of the claims attached to this utility model.
