They suffer from numerous on-site devices, complex wiring, inconsistent construction specifications, electrical safety risks, and poor data collection quality. Therefore, further optimization and adjustment of the integrated oil well electronic control skid is urgently needed. Summary of the Invention

DETAILED DESCRIPTION

[0018] The present invention provides an oil well electronic control integrated skid-mounted device, which adopts intelligent standardization and modular design, has the characteristics of stable operation, convenient construction, safety and reliability, meets the requirements of intelligent management and unmanned operation of oilfield enterprises, and has high economic efficiency and market prospects.

[0019] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. Example 1

[0020] The present invention provides an oil well electronic control integrated skid-mounted device, comprising: a box-type skid-mounted device main structure, and a PLC control module, a drive control module, a communication module, a spread spectrum base station, and a power distribution module installed in the box-type skid-mounted device main structure.

[0021] The PLC control unit further includes a microprocessor unit and a memory unit. The drive control module is used to drive and control the 24V relay associated with the oil well electronic control integrated skid. The communication module consists of a first transceiver unit and a second transceiver unit. The first transceiver unit is specifically used to establish communication with other equipment at the oilfield well station, while the second transceiver unit is used for debugging and backup.

[0022] Specifically, as a preferred embodiment of the present invention, a set of specific circuits is provided here for reference. Figure 1 As shown in the figure, the microprocessor unit in the PLC control unit uses the MSP430F149 chip. This MSP430F149 chip is a highly versatile, low-power 16-bit microprocessor unit. It is equipped with a high-precision 12-bit analog-to-digital converter (ADC12) and a reduced instruction set MCU. It has faster computing speed and also improves the overall working efficiency of the microprocessor unit. It is worth noting that, as Figure 1 As shown in the figure, the DVSS, AVSS, VeREF+, and VeREF- pins of the MSP430F149 chip are all grounded.

[0023] And as Figure 2 As shown in FIG, the memory unit in the PLC control unit uses a chip model FM31256. The VSS pin of the FM31256 chip is grounded, the SDA pin of the FM31256 chip is connected to the TB2 pin of the MSP430F149 chip, and the SCL pin of the FM31256 chip is connected to the TB3 pin of the MSP430F149 chip.

[0024] In addition, as a more preferred embodiment of the present invention, the drive control module installed in the main structure of the box-type skid-mounted device can preferably use a compound transistor array with a chip model of ULN2003 to drive and control the 24V relay that is matched with the oil well electronic control integrated skid-mounted device.

[0025] It's important to note that by driving and controlling a 24V relay using the ULN2003's composite transistor array, a variety of extended functions can be implemented. For example, in oil well electronic control integrated skids, environmental monitoring often requires additional equipment such as hazardous gas monitoring and temperature detection. Based on preset monitoring reference values, these environmental factors trigger corresponding control commands from the drive control module, driving the stepper motor to perform the aforementioned emergency response (e.g., providing audible and visual alarms in the event of a hazardous gas leak).

[0026] A communication module is also installed in the main structure of the box-type skid-mounted device. The communication module consists of a first transceiver unit and a second transceiver unit. Figure 3 and Figure 4 As shown, both the first and second transceiver units use the 74HC245 chip. The A0, A1, A2, A3, A4, A5, A6, and A7 pins of the 74HC245 chip in the first transceiver unit are connected one-to-one with the TA0, ADC 12CLK, Rosc, TA2, TA1, TA0, TAINCLK, and ACLK pins of the MSP430F149 chip, respectively. The A4, A5, A6, and A7 pins of the 74HC245 chip in the second transceiver unit are connected one-to-one with the UCLK0, SOMI0, SIMO0, and STE0 pins of the MSP430F149 chip, respectively. The A0, A1, and A2 pins of the 74HC245 chip in the second transceiver unit are connected one-to-one with the TB1, TB0, and RXD1 pins of the MSP430F149 chip, respectively.

[0027] It's worth noting that the first transceiver unit in the aforementioned communication module is used to establish communication interconnections with other equipment at the oilfield well station, thereby transmitting and receiving various data collected by each device. In a preferred embodiment of the present invention, the communication module is also communicatively connected to a spread-spectrum base station, preferably a TAIT855 / 856 ground-based radio. This ground-based radio features full-duplex communication and, when equipped with a high-gain omnidirectional antenna, can achieve data communication coverage of tens of kilometers. The second transceiver unit is preferably used as a debugging standby, for example, to allow technicians to update preset control instructions and parameters for the oil well electronic control integrated skid. Example 2

[0028] The second embodiment includes all the technical features of the first embodiment. In addition, the second embodiment is further limited to the following technical features: Specifically, as a preferred embodiment of the present invention, a power distribution module is further configured in the main structure of the box-type skid-mounted device. The power distribution module is composed of a power supply and an LDO voltage stabilizing unit.

[0029] The power supply converts a 220V AC input voltage into a 24V / 5V / 3.3V DC output voltage. The LDO voltage regulator, for example, uses an AAT3221 chip to stabilize the output voltage of the power supply. Specifically, the IN pin of the AAT3221 chip is connected to a +24V DC voltage, and the VOUT pin of the AAT3221 chip is connected to the DVCC and AVCC pins of the MSP430F149 chip, respectively.

[0030] In addition, as an optional embodiment of the present invention, a frequency conversion adjustment unit can be further configured at the power distribution module, thereby further expanding the power supply mode of the power distribution module to meet the power supply needs of different module units. Example 3

[0031] The third embodiment includes all the technical features of the first embodiment. In addition, the third embodiment further includes the following technical features: The main structure of the box-type skid-mounted device is equipped with a partition. Specifically, this partition is used to separate the main structure of the box-type skid-mounted device into a control and communication cabinet and a power distribution cabinet. The control and communication cabinet can be used to house communication and control electrical modules such as PLC control modules, drive control modules, and communication modules, while the power distribution cabinet is preferably used to house power distribution modules. This arrangement aims to integrate and separate modules of different voltage levels (strong and weak).

[0032] In addition, as a more preferred embodiment of the present invention, in order to facilitate the lifting and fixing of the main structure of the box-type skid-mounted device provided by the present invention, it is further preferred to provide a plurality of lifting protrusions on the top of the main structure of the box-type skid-mounted device, and to provide an installation socket for fixing the main structure of the box-type skid-mounted device on the outer top of the main structure of the box-type skid-mounted device.

[0033] Furthermore, the main structure of the box-type skid-mounted device is preferably configured with a human-computer interaction unit including an input keyboard, a liquid crystal display panel, and a signal indicator light; and an alarm unit including a sound alarm and an optical alarm.

[0034] The present invention provides an integrated skid-mounted oil well electronic control system. This system comprises a box-type skid-mounted main structure, and structural units such as a PLC control module, a drive control module, a communication module, a spread spectrum base station, and a power distribution module, mounted within the box-type skid-mounted main structure. This skid-mounted oil well electronic control system, with these structural features, offers excellent versatility. Its various modules and functional units are easily installed, interchangeable, and maintained, effectively meeting various usage scenarios at oilfield well sites.

[0035] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention.
