[0044] To better understand the purpose, structure, and function of this invention, the invention will be described in detail below with reference to the accompanying drawings.

[0045] Example 1

[0046] like Figure 1 As shown, this embodiment provides a remote power-off restart device for oilfield field automatic control equipment, including: a control module 2 and a power management module 1, a human-machine interface module 3, an output module 4 and a wireless communication module 5 respectively connected to the control module 2;

[0047] Power management module 1 is used to provide power to the remote power-off restart device;

[0048] The wireless communication module 5 establishes a wireless communication connection with the operation terminal and performs remote data transmission, transmitting the operation instructions received from the operation terminal to the control module 2;

[0049] The control module 2 has a built-in control system, which is used to control the output module 4 to operate according to the received operation instructions;

[0050] Control module 2 connects to the field devices to enable them to start and stop.

[0051] The human-machine interface module 4 is used to connect the control module 2 to the operating system platform to realize the parameter setting and operation command configuration of the remote power failure restart device.

[0052] The remote power-off and restart device for oilfield field automation equipment of the present invention enables multiple logical functions to achieve remote power-off and power-on through a single remote command, reducing the complexity of user operation and making it highly practical in the field.

[0053] The remote power-off restart device only cuts off the power to the RTU or bridge during operation, resetting the IoT devices without affecting the control power supply. It does not disrupt the normal operation of the oil well throughout the process. Wireless network transmission is used, with a dedicated mobile VPN link and a dedicated fiber optic link directly connecting to the server, ensuring network security. The background operation employs an authorization mechanism to guarantee the permission granted for each operation, and confirmation pop-ups appear during operation to prevent accidental backend operations.

[0054] Example 2

[0055] The difference from Embodiment 1 is that the remote power-off restart device for oilfield field automatic control equipment is in an extremely harsh environment for a long time. Therefore, the reliability of the remote power-off restart device itself must be improved. Thus, in this embodiment, the power management module adopts surge protection circuit and opto-isolation circuit.

[0058] The difference from Embodiments 1-2 is that in this embodiment, the human-machine interface module connects the control module to the operating system platform via wired or wireless means, and the operating system platform is installed on the selected smart device.

[0059] In some preferred embodiments of the present invention, the human-machine interface module has an RS485 interface and Bluetooth communication function. It can communicate with the device through RS485 wired and Bluetooth wireless methods. It can be connected to a computer or a mobile phone. Using dedicated supporting software, the power-off duration of the restart device can be set according to the power-off requirements of different devices on site. It can also remotely set parameters, remotely configure commands, and remotely modify settings.

[0060] The RS485 interface can also be configured to read relevant diagnostic parameters from the field, providing backend users with certain reference information to determine the type of fault in the field.

[0061] Furthermore, the parameters of the remote power-off restart device include at least the power-off duration.

[0062] Furthermore, the control module enables backend management, including a database, to record field equipment information and operation process information. Storing field equipment information in the database creates a client / server interface operation mode. This achieves unified maintenance of equipment information and detailed recording of operation processes, including system operator information, operator restart operation time, and restarted device name. The restart records can be analyzed to determine the number of restarts within a certain period, filtering out devices with high failure rates.

[0063] Example 4

[0064] The difference from Examples 1-3 is that, as Figure 2 As shown, in this embodiment, the output module has an independently controlled first DO circuit and a second DO circuit. The first DO circuit is connected to the field controller, and the second DO circuit is connected to the field transmission equipment.

[0065] Furthermore, the first DO circuit includes resistors R32, R33, and R34, capacitor C19, transistor Q2, diode D13, light-emitting diode LED07, and interface IO1.

[0066] One end of resistor R32 is connected to the control system, and the other end is connected to capacitor C19, resistor R33 and the base of transistor Q2 respectively. The other end of capacitor C19, the other end of resistor R33 and the emitter of transistor Q2 are grounded.

[0067] The collector of transistor Q2 is connected to the positive terminal of diode D13 and interface IO1, respectively;

[0068] The power management module is connected to the negative terminal of diode D13 and resistor R34 respectively;

[0069] Resistor R34 is connected to the positive terminal of LED07;

[0070] The negative terminal of the LED07 is connected to interface IO1.

[0071] Furthermore, interface IO1 includes current relay KC0, which includes normally open interface DO0+, normally closed interface DO0-, and common interface DO0C.

[0072] Furthermore, the second DO circuit includes resistors R36, R37, and R38, capacitor C20, transistor Q3, diode D14, light-emitting diode LED08, and interface IO2.

[0073] One end of resistor R36 is connected to the control system, and the other end is connected to capacitor C20, resistor R37 and the base of transistor Q3 respectively. The other end of capacitor C20, the other end of resistor R37 and the emitter of transistor Q3 are grounded.

[0074] The collector of transistor Q3 is connected to the positive terminal of diode D14 and interface IO1, respectively;

[0075] The power management module is connected to the negative terminal of diode D14 and resistor R38 respectively;

[0076] Resistor R38 is connected to the positive terminal of LED08;

[0077] The negative terminal of the LED08 is connected to interface IO2.

[0078] Furthermore, interface IO2 includes current relay KC1, which includes normally open interface DO1+, normally closed interface DO1-, and common interface DO1C.

[0079] By designing two DO channels, the server can remotely set the reset sequence and reset duration of the two DO channels respectively, thereby meeting the reset requirements of different devices in the field. When data goes offline for unknown reasons in the field, the remote control terminal can perform power-on reset operations on the controller and transmission equipment through the two DO channels. Through remote power-on reset, the equipment can be restored to online status in a timely manner, avoiding the need for frequent on-site operations.

[0080] The control module outputs a high-level signal, driving the transistor to conduct, and finally driving the relay to achieve a power-off action. The two channels can be controlled independently without affecting each other.

[0081] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention are included within the scope of protection of the present invention.
