[0024] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0025] In the description of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0026] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0027] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of the embodiments of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0028] In related technologies, for various instruments and equipment in laboratories of the petroleum and petrochemical industry, ordinary power strips can be used to meet power needs. Due to the increase in the number of sockets, the number of instruments and equipment that can be powered on is greatly increased.

[0029] On the one hand, in existing power supply systems, when multiple instruments and equipment start up simultaneously, overload current, circuit faults, equipment malfunctions, and excessive voltage fluctuations often cause the upstream circuit to trip, resulting in all sockets on the circuit becoming unusable. Furthermore, the direct consequence of multi-level connections in ordinary sockets is an increased likelihood of individual sockets being overloaded, leading to overheating and potentially fires, posing a significant safety hazard.

[0030] On the other hand, laboratories in the petroleum and petrochemical industry harbor numerous potential hazards. For example, frequently used raw materials or intermediate products are often flammable and explosive. Due to factors such as clothing, climate, and friction, static electricity is generated when the human body rubs against, separates from, or comes into contact with objects. In dry environments, this static charge accumulates on the human body's surface. When it comes into contact with flammable substances, the static charge is released, forming a spark and potentially causing a fire, posing a significant safety hazard.

[0031] Furthermore, frequent plugging and unplugging can damage sockets. Plugs have two small copper contacts; frequent plugging and unplugging can cause these contacts to bend or deform, making it difficult to insert the plug or resulting in a loose wire connection and decreased electrical performance. Under normal circumstances, minimizing the frequency of plugging and unplugging can better protect sockets. However, leaving power plugs on for extended periods can also lead to electrical safety hazards, shorten the lifespan of appliances, and increase the risk of electrical equipment malfunctions and fires. Even when appliances are off, appliances left plugged in for long periods continue to consume electricity, resulting in energy waste and additional electricity bills.

[0032] In addition, due to the large number of instruments and equipment in the laboratory, the excessively long power cords of the instruments are often placed crisscrossingly on the laboratory bench, making it look messy and increasing the difficulty of cleaning the laboratory bench.

[0033] In order to address the shortcomings of related technologies, Figure 1 This is a structural schematic diagram of the multifunctional split-type intelligent power distribution pile provided in this application, as shown below. Figure 1 As shown, the power distribution station mainly includes a main circuit 1, a control circuit 2, and a socket bar 3. The control circuit 2 includes an electrostatic discharge protection module 21 and a timer protection module 22.

[0034] The main circuit is used to connect to the power supply. The socket strip, electrically connected to the main circuit, is used to distribute power to various instruments and equipment. The control circuit, electrically connected to both the main circuit and the socket strip, is used to control the power supply to the socket strip; the control circuit includes an electrostatic discharge (ESD) protection module and / or a timer protection module; the ESD protection module eliminates static charge accumulated on the operator's body when the operator presses the ESD ball and connects the power supply circuit between the main circuit and the socket strip; the timer protection module disconnects the power supply circuit between the main circuit and the socket strip after a preset conduction time has elapsed.

[0035] Specifically, the multifunctional split-type intelligent power distribution pile provided in this application embodiment can provide the laboratory with multiple sets of sockets with different power and independent power supply. By controlling the power distribution pile to eliminate static charge on the human body before powering on and controlling the power supply time of the sockets at a time, it can meet the safe power needs of multiple devices at the same time, maintain the safety of laboratory equipment, and protect the health of laboratory personnel.

[0036] Structurally, the multi-functional split-type intelligent power distribution pile mainly includes the main circuit, control circuit, and socket bar.

[0037] The main circuit is primarily used to connect to an external power source, such as a three-phase five-wire 380 / 220VAC (alternating current). The socket strips are electrically connected to the main circuit and are used to distribute the power to various instruments and equipment in the laboratory.

[0038] Understandably, a power strip can include multiple sockets with different output power and voltage to meet the power needs of different instruments and equipment. For example, for high-power, high-voltage driven instruments and equipment, they can be directly connected to the various power lines of the main circuit to obtain 380VAC power; for low-power, low-voltage driven instruments and equipment, they can be connected to any live wire of the main circuit to obtain 220VAC power.

[0039] The control circuit, connected to the main circuit and the socket bar, is used to control the power supply to the socket bar. When the power supply to the socket bar is on, each socket in the socket bar is energized; when the power supply to the socket bar is off, each socket in the socket bar is de-energized.

[0040] Operators' (users') bodies may accumulate a large amount of electrostatic charge. This electrostatic charge can generate a momentary high voltage upon contact with or proximity to a power source, which may interfere with the power supply circuitry or cause equipment malfunction. Electrostatic discharge can cause overvoltages in the power supply circuitry, damaging internal components and affecting its stability and reliability. The control circuitry may include an electrostatic discharge protection module. This module eliminates the electrostatic charge accumulated on the operator's body when the operator touches the electrostatic discharge ball, simultaneously activating the power supply circuit between the main circuit and the socket, ensuring power to the socket.

[0041] A timer and voice alarm can be set in the static electricity elimination protection module. The timer tracks the duration for which the operator presses the static electricity elimination ball. If the operator's pressing time does not exceed a preset time threshold, the timer sends a switch signal to the voice alarm, triggering the alarm to prompt the operator to continue pressing the static electricity elimination ball, thus improving the static electricity elimination effect. The preset time threshold can be set as needed, for example, 3 seconds.

[0042] The control circuit may also include a timing protection module. This module disconnects the power supply between the main circuit and the socket strip after a preset on-time has elapsed. The preset on-time can be set as needed. The timing protection module controls the energized usage time of the socket strip.

[0043] The multifunctional split-type intelligent power distribution pile provided in this application embodiment has a main circuit for connecting to a power source; a power strip for distributing power to various instruments and equipment; and a control circuit for controlling the power supply to and from the power strip. The control circuit includes an electrostatic discharge (ESD) protection module and / or a timer protection module. The ESD protection module eliminates accumulated static charge on the operator's body when the operator presses the ESD ball and connects the power supply circuit between the main circuit and the power strip. The timer protection module disconnects the power supply circuit between the main circuit and the power strip after a preset conduction time. By setting up the power strip, the safe power needs of multiple laboratory devices can be met. The ESD protection module and timer protection module allow for safety monitoring and management of experiments, such as requiring the operator to eliminate accumulated static charge on their body before powering on the instruments and equipment, and controlling the power supply time of the power strip. This achieves the goals of maintaining laboratory equipment safety, improving the experimental safety environment and facilities, and protecting the health of laboratory personnel. The structure is simple, the manufacturing cost is low, and the application range is wide.

[0044] In some embodiments, Figure 2 This is a structural front view of the multifunctional split-type intelligent power distribution pile provided in this application, such as... Figure 2 As shown, the control circuit also includes a relay 450 and a contactor 460; the static eliminator protection module includes a left-hand static eliminator module 410 and a right-hand static eliminator module 420; the timing protection module includes a timer 470.

[0045] Specifically, the left-hand antistatic ball module can be an antistatic ball that the operator can touch with their left hand. It removes static electricity when the operator touches it with their left hand and connects the circuit when pressed. The right-hand antistatic ball module operates on the same principle as the left-hand module.

[0046] Figure 3 This is a control schematic diagram of the multifunctional split-type intelligent power distribution pile provided in this application, such as... Figure 3 As shown, this diagram is based on the circuit diagram of the main circuit of the multi-functional split-type intelligent power distribution pile and the ladder diagram of the programmable logic controller (PLC) for the control circuit. In the diagram, PE represents the ground wire, N represents the neutral wire, and L1, L2, and L3 represent the live wires.

[0047] The timer includes a coil, a first normally closed contact, and a second normally closed contact. The first and second normally closed contacts form a pair of contacts connected to the circuit. The timer starts timing when the coil is energized; that is, when the coil is activated or energized, the timer begins running. When the timing period expires, the timer's normally open contact closes, and the normally closed contact opens. Furthermore, the timer coil can be reset; after reset, its normally open contact opens, its normally closed contact closes, and the current value is reset. These operations are implemented through the coil in the PLC, and the coil's state can be controlled by the program to achieve operations such as starting, stopping, and resetting the timer.

[0048] A relay includes a coil, a first normally open contact, a second normally open contact, a third normally open contact, and a fourth normally open contact. The first and second normally open contacts form a pair of contacts that are connected to the circuit, and the third and fourth normally open contacts also form a pair of contacts that are connected to the circuit. The relay coil is mainly used to energize itself through an input voltage, which in turn attracts the two pairs of normally open contacts to close, thus connecting the circuit. When the coil is de-energized, the two pairs of normally open contacts open, thus disconnecting the circuit.

[0049] A contactor includes a coil, a first normally open contact, and a second normally open contact. The first and second normally open contacts form a pair of contacts that are connected to the circuit. The contactor's coil is mainly used to energize itself through an input voltage, which in turn attracts the pair of normally open contacts to close, thus connecting the circuit. When the coil is de-energized, the normally open contacts open, thus disconnecting the circuit.

[0050] From the perspective of circuit connection: The first end of the left-hand static eliminator module is electrically connected to the live wire of the main circuit, and the second end is electrically connected to the first end of the right-hand static eliminator module; the second end of the right-hand static eliminator module is electrically connected to the first normally closed contact of the timer; the second normally closed contact of the timer is electrically connected to the first end of the relay coil and the first end of the timer coil.

[0051] The second terminal of the relay coil and the second terminal of the timer coil are electrically connected to the second terminal of the socket bar (which can be the neutral wire); the first normally open contact of the relay is electrically connected to the first terminal of the socket bar, and the second normally open contact is electrically connected to the first normally closed contact of the timer; the third normally open contact of the relay is electrically connected to the first terminal of the socket bar, and the fourth normally open contact is electrically connected to the first terminal of the contactor coil; the second terminal of the contactor coil is electrically connected to the second terminal of the socket bar.

[0052] The first normally open contact of the contactor is electrically connected to the live wire of the main circuit, and the second normally open contact is electrically connected to the first end of the socket block.

[0053] In the above embodiment, the first end of the socket bar is electrically connected to the ground wire of the main circuit, the second end is electrically connected to the neutral wire of the main circuit, and the third end is electrically connected to the ground wire of the main circuit.

[0054] From the perspective of circuit function: The left-hand and right-hand antistatic ball modules are used to eliminate static electricity accumulated on the human body and to connect the control circuit. They also connect the main circuit via a contactor to allow the socket to be energized.

[0055] The timer enables the multi-functional split-type intelligent power distribution pile to control the power supply time of the socket row.

[0056] In some embodiments, such as Figure 2 As shown, the control circuit also includes a rotary switch 440 and a power indicator light 430; the rotary switch is used to control the control circuit to be turned on or off; the power indicator light is used to indicate the working status of the control circuit.

[0057] Specifically, the circuit connection of the rotary switch and the power indicator is as follows: Figure 3 As shown, the first end of the rotary switch is electrically connected to the first end of the relay coil, and the second end is electrically connected to the second end of the socket bar; the first end of the power indicator light is electrically connected to the first end of the relay coil, and the second end is electrically connected to the second end of the relay coil.

[0058] Both the rotary switch and the power indicator light are located in the control circuit. That is, the rotary switch is electrically connected to the relay, contactor, timer and power indicator light. The rotary switch is used to assist in connecting the control circuit, and the power indicator light is used to indicate the on and off status of the control circuit by turning the light on or off.

[0059] From the perspective of operation methods: By turning on the rotary switch, the operator presses and holds both the left and right antistatic ball modules for more than 3 seconds. At this time, the relay closes, achieving self-locking, energizing the timer, and starting the countdown. Releasing the hands keeps the relays connected, activating the control circuit, and keeping the power indicator light constantly on. Simultaneously, the contactor coil and contacts close, activating the main circuit, energizing all sockets, and putting the system into operation.

[0060] It is understood that the rotary switch can be a button or a touch button, etc. The power indicator light can be a light-emitting diode (LED), but in other possible examples, it can also be other types of light-emitting devices; this application does not limit this.

[0061] In some embodiments, the socket bar includes multiple sockets; at least two of the multiple sockets have different power supplies.

[0062] Specifically, Figure 4 This is a top view of the multifunctional split-type intelligent power distribution pile provided in this application, as shown below. Figure 4 As shown, the multi-functional split-type smart power distribution pile may include at least one set of sockets, such as the first set of sockets 310, the second set of sockets 320, the third set of sockets 330, and the fourth set of sockets 340.

[0063] Each outlet bar may include multiple outlets, at least two of which have different power supplies, for example, they may include power supplies with different power ratings of 10 amps (A) and 16 amps (A).

[0064] The contactor is electrically connected to the left-hand antistatic ball module, the right-hand antistatic ball module, the relay, the timer, the air switch, the first group of sockets, the second group of sockets, the third group of sockets, and the fourth group of sockets, so as to energize a certain group of sockets or all of the sockets and form an antistatic protection circuit, which is used to control the closing of the main circuit and the antistatic protection circuit.

[0065] The timer is electrically connected to the relay and contactor to form a timing protection circuit, which controls the power-off of the first, second, third, and fourth sets of sockets to control the power-on time of the sockets.

[0066] In some embodiments, such as Figure 2 As shown, an air switch 480 is installed in the power supply circuit between the main circuit and the socket bar. The air switch is electrically connected to the external power grid and is used to control the connection or disconnection of the power supply circuit between the main circuit and the socket bar, as well as to provide automatic power-off protection in the event of a short circuit or negative voltage in the main circuit.

[0067] Specifically, under certain circumstances, when a short circuit or negative pressure occurs in the test equipment, one or more circuit breakers can trip in a timely manner, thereby promptly cutting off power to the static electricity protection circuit and the timing protection circuit, ensuring the safety of the test equipment.

[0068] In addition, if you wish to disconnect the power at any time after the test is completed or during the test, you can do so manually. One method is to selectively disconnect the circuit breaker for a specific circuit, which will disconnect the power supply to the sockets on that circuit, while the sockets on other circuits will still function normally. Another method is to turn off the rotary switch on the distribution post, which will disconnect the power to all sockets.

[0069] In some embodiments, such as Figure 2 As shown, the multi-functional split-type intelligent power distribution pile also includes a socket strip support frame 300. The socket strip support frame is used to install the socket strip; the socket strip support frame is located on the front and / or back of the multi-functional split-type intelligent power distribution pile.

[0070] Specifically, the socket bar support frame consists of two parallel sets: the first, second, third, and fourth sets of socket bars, all mounted on the surface of the support frame, allowing both sets to be powered. Each set includes one three-hole socket and four five-hole sockets. The three-hole sockets have a rated current of 16A, suitable for instruments with a maximum rated power of 3500W; the five-hole sockets have a rated current of 10A, suitable for instruments with a maximum rated power of 2200W. All four sets of socket bars are electrically connected to rotary switches, contactors, and external instruments to control their power supply.

[0071] It is understood that there can be multiple sets of socket bar support brackets, and socket bars can be installed in any set of socket bar support brackets. There can be 1 to 4 sets of socket bars, and each set of socket bars can have 1 to 4 sockets. The rated current value of the sockets can also be 10A or a combination of 10A and 16A within the load range. This application embodiment does not impose any restrictions on this.

[0072] In some embodiments, such as Figure 2 As shown, the multi-functional split-type intelligent power distribution pile also includes a left box 200 and a right box 100; the right side wall of the left box 200 is provided with a left support hole 220; the left side wall of the right box 100 is provided with a right support hole 120.

[0073] The two ends of the socket support bracket are located in the left support hole and the right support hole.

[0074] In some embodiments, such as Figure 2As shown, a left chamber 210 is provided inside the left housing 200; a right chamber 110 is provided inside the right housing 100.

[0075] The air switch is located in either the left or right chamber; the control circuit is located in the other of the left and right chambers. The diagram only shows the air switch in the left chamber and the control circuit in the right chamber; this can be switched according to actual needs.

[0076] The multifunctional split-type intelligent power distribution pile provided in this application embodiment has two independent chambers separated in the right and left boxes. The relays, contactors, timers and air switches in the control circuit are respectively set in the two chambers, which not only facilitates the installation of the control circuit, but also facilitates the maintenance and replacement of various components in the control circuit. Support holes are opened on the side walls of the right and left boxes, and the two ends of the socket support frame can be easily mounted on the support holes of the right and left boxes.

[0077] In some embodiments, such as Figure 2 As shown, the multi-functional split-type intelligent power distribution pile also includes a coarse toothed cable groove 500, located in the lower part between the left and right boxes. It can be used to store excessively long power cords of instruments and equipment. When cleaning the experimental table, it can be moved as a whole, which makes it easier to clean the table and achieves the purpose of aesthetics and improved experimental environment.

[0078] In some embodiments, when setting up the multifunctional split-type intelligent power distribution pile provided in this application, the right box, left box, socket support frame, and coarse toothed wire groove can all be standard parts. For example, the dimensions of the right box and left box are 30cm (cm) × 25cm × 15cm, the dimensions of the socket support frame are 200cm × 8cm × 10cm, and the dimensions of the coarse toothed wire groove are 150cm × 8cm × 10cm.

[0079] It is understandable that the right housing, left housing, socket support bracket, and coarse-toothed wire groove can also be of other sizes, as long as they can be manufactured as a standard part. A left chamber is formed within the right housing, in which relays, contactors, and timers are fixedly installed; a right chamber is formed within the left housing, in which an air switch is fixedly installed. Furthermore, in this embodiment, a wire groove cavity is formed within the coarse-toothed wire groove, where excessively long wires are placed. The surface of the wire groove cavity has 8mm × 10mm blocking teeth, allowing the wires of instruments and equipment to pass through.

[0080] In some embodiments, the right and left housings may be made of the same material. For example, in some examples, both the right and left housings may be made of insulating material. The socket bar support frame and the toothed cable tray may also be made of the same material. For example, in some examples, both the socket bar support frame and the toothed cable tray may be made of fire-retardant polyvinyl chloride (PVC).

[0081] In some embodiments, by setting up a right housing to fix the relays, contactors, and timers inside the left chamber using screws, bolts, or other means, and by placing the left housing and the circuit breaker inside the left chamber, the protection capabilities for the relays, contactors, timers, and circuit breakers are improved, making the components less prone to damage and effectively extending their service life. By setting up coarse-toothed wire grooves to place excessively long wires of the instrument within the groove cavity, the protection capabilities of the wires are improved, making them less prone to damage. The surface of the wire groove cavity has barrier teeth, preventing the wires from shaking after installation and resulting in a more aesthetically pleasing wiring arrangement.

[0082] In some embodiments, the arrangement order of the power indicator light and the rotary switch can also be other than other orders. This application embodiment does not limit the arrangement order of the power indicator light and the rotary switch. The installation positions of the left-hand and right-hand antistatic ball modules can also be other than other positions. This application embodiment does not limit the installation positions of the left-hand and right-hand antistatic ball modules.

[0083] In some embodiments, the left-hand antistatic ball module and the right-hand antistatic ball module are placed on the top of the right housing, and the power indicator light and rotary switch are installed on the side of the right housing with screws from top to bottom.

[0084] The multi-functional split-type intelligent power distribution pile provided in this application is designed to meet the safe power use of multiple devices in the laboratory, eliminate static electricity from the operator's body before the experiment, and time the power supply time of the socket. Specific operating methods include: First, set the desired usage time for the timer, connect the external power grid, close the air switch, and turn on the rotary switch. Press and hold both the left and right antistatic ball modules for at least 3 seconds. At this time, the relay closes, achieving self-locking, energizing the timer, and starting the countdown. Release your hands; the relay remains connected, the control circuit is activated, and the power indicator light illuminates. Simultaneously, the contactor coil and contacts close, connecting the main circuit, energizing all sockets, and putting them into operation. This ensures that the multi-functional split-type intelligent power distribution station provides power to laboratory instruments and equipment while eliminating static charge on the operator's body. This prevents static charge buildup on the body surface due to clothing, weather, friction, etc., which could release static charge and create sparks when in contact with flammable materials during experiments, potentially causing a fire.

[0085] Then, when using external instruments and equipment correctly, the timer contacts will automatically disconnect when the preset timer usage time is reached, the relay coil will be de-energized, the contactor will be de-energized, the control circuit will be disconnected, the main circuit will be disconnected, the socket will be de-energized, and the power supply to the external instruments and equipment will also be disconnected. This is to avoid damage to the socket caused by frequent plugging and unplugging, or the long-term failure to unplug the power cord or the power socket being energized for too long, which may lead to electrical safety hazards and shorten the life of electrical appliances, increasing the risk of electrical equipment failure and fire.

[0086] Under normal circumstances, when a short circuit or negative pressure occurs in the test equipment, one or more circuit breakers can trip in time, thereby promptly cutting off power to the static electricity protection circuit and the timing protection circuit, ensuring the safety of the test equipment.

[0087] In addition, power can be manually cut off at any time during or after the test if needed. One method is to selectively disconnect the circuit breaker for a specific circuit, which will disconnect the power to the sockets on that circuit, while the sockets on other circuits will still function normally. Another method is to turn off the rotary switch on the distribution pile, which will disconnect power to all sockets.

[0088] The multifunctional split-type intelligent power distribution pile provided in this application can provide the laboratory with multiple sets of sockets of different power and can be independently powered, meeting the safe power needs of multiple devices at the same time. It requires the operator to remove the static charge accumulated on the human body by touching the anti-static ball before the power can be turned on to start the instrument and equipment for the experiment. It can also monitor and manage the safety of the experiment by controlling the power supply time of the sockets, thereby achieving the purpose of maintaining the safety of laboratory equipment, improving the experimental safety environment and facilities, and protecting the health of laboratory personnel.

[0089] Figure 5 This is a flowchart illustrating the control method for the multifunctional split-type intelligent power distribution pile provided in this application, as shown below. Figure 5 As shown, the method includes: Step 510: Obtain the power supply status of the main circuit and the closing status of the air switch between the main circuit and the socket. Step 520: When the power supply is connected and the closed state is closed, the control circuit is turned on based on the pressing state of the left-hand antistatic ball module and the right-hand antistatic ball module, and the timer is controlled to start timing. Step 530: Disconnect the control circuit when the timer's timing duration is greater than or equal to the preset conduction duration; The socket is powered when the control circuit is on and de-powered when the control circuit is off.

[0090] Specifically, the power supply status of the main circuit indicates whether it is connected to an external power grid. The closed state of the circuit breaker between the main circuit and the socket bar indicates whether power supply to the socket bar is permitted; closed indicates permitted, open indicates not permitted.

[0091] When the power supply is connected and the closed state is closed, it can be determined that the external power grid is connected and the socket is allowed to be powered. The control circuit can be activated by pressing the left and right antistatic ball modules, so that the operator can eliminate the static charge accumulated on the human body before the test, and the main circuit is connected through relays, timers and contactors.

[0092] The socket's usage time is monitored by a timer. When the timer reaches the preset conduction duration, the timer contacts automatically open, de-energizing the relay coil, the contactor, the control circuit, and the main circuit, thus de-energizing the socket. The socket is energized when the control circuit is on and de-energized when the control circuit is off.

[0093] The control method for the multifunctional split-type intelligent power distribution pile provided in this application embodiment acquires the power supply access status of the main circuit and the closed status of the air switch between the main circuit and the socket. When the power supply access status is "accessed" and the closed status is "closed", the control circuit is activated based on the pressing status of the left-hand and right-hand anti-static ball modules, and the timer is controlled to start timing, so that the relay coil is energized and self-locked. When the timing duration of the timer is greater than or equal to the preset conduction duration, the control circuit is disconnected. This realizes the ability to require the operator to eliminate the static charge accumulated on the human body before powering on the instrument and equipment for testing by pressing the anti-static ball, and to control the power supply time of the socket for testing, thereby achieving the purpose of maintaining the safety of laboratory equipment, improving the experimental safety environment and facilities, and protecting the health of experimental personnel.

[0094] In some embodiments, the method further includes: Receives control commands from any air switch; control commands include closing commands or tripping commands. Based on control commands, the socket corresponding to any circuit breaker can be powered on or de-powered.

[0095] Specifically, control commands can also be sent to the air switch manually or via control. Control commands include closing commands or tripping commands.

[0096] According to the control command, any air switch can be closed or tripped, and the corresponding socket will be energized or de-energized accordingly.

[0097] The control method for the multifunctional split-type intelligent power distribution pile provided in this application embodiment has two aspects: first, selectively disconnecting the air switch of a certain circuit will disconnect the power supply to the socket bar of that circuit, while the socket bars of other circuits can still be used normally; second, closing the rotary switch of the power distribution pile will disconnect the power to all sockets, thereby achieving the purpose of test safety and protecting the instruments and equipment.
