Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of equipment debugging, and in particular to a single debugging device and a debugging method for a switch actuator. Background Art
[0002] Switch actuators are divided into two types: single-control (single command channel) and dual-control (dual command channels). Single-control devices include single-control pneumatic switch valves and single-control motor devices, and dual-control devices include dual-control pneumatic switch valves, dual-control electric switch valves and dual-control motor devices.
[0003] Before installing such actuators, it is necessary to perform an action test in advance to verify that the valve has not caused any functional loss or equipment damage during transportation or storage. After the actuator and the valve it controls are installed, the cable channel between the actuator and the control system must be verified, as well as the action test after the valve is installed. It may be necessary to perform single-unit debugging of the actuator in order to quickly find and locate the fault point, quickly adjust the switch limit position, etc.
[0004] At present, there is no single debugging device that can be used for both single-control and dual-control actuators to provide convenient and quick debugging for debuggers. Debuggers can only load 24V DC directly to the actuator to actuate the equipment in the traditional way. They cannot intuitively and effectively observe the signal feedback after the limit action, nor can they determine the consistency between the switch command and the feedback.

[0030] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0031] During the installation and commissioning of a spent fuel reprocessing plant, a large number of pneumatic switch valves, motors and other actuators are installed and debugged. In order to improve the debugging efficiency and debugging quality and meet the installation, debugging, and production operation requirements of various scenarios such as modern spent fuel reprocessing plants, an embodiment of the present invention provides a switch actuator monomer debugging device, which can be applicable to the debugging of various types of equipment, has low cost, simple operation, state feedback function, and high stability in harsh environments.
[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, an embodiment of the present invention provides a single debugging device for a switch actuator, comprising:
[0033] A human-machine interface module, used for inputting command action signals to the logic operation module and outputting status feedback of the actuator to be tested, wherein the actuator to be tested includes a single-control actuator to be tested and a dual-control actuator to be tested;
[0034] An external interface module is used to connect the logic operation module and the actuator to be tested;
[0035] The logic operation module is used to generate a corresponding switch command according to the input command action signal, output the switch command to the single-control actuator to be tested or the dual-control actuator to be tested through the external interface module, and transmit the feedback signal of the actuator to be tested to the human-machine interface module. The human-machine interface module outputs the status feedback of the actuator to be tested according to the feedback signal.
[0036] Specifically, the human-machine interface module includes a single-acting and double-acting switching knob SA, an on button SB1, an off button SB3, an on indicator light HR, and an off indicator light HG. The single-acting and double-acting switching knob SA is used to switch the state of the switch-type actuator monomer debugging device to a single-control state or a double-control state. The on button SB1 and the off button SB3 are respectively used to input corresponding command action signals. The on indicator light HR and the off indicator light HG are respectively used to light up or go out when the actuator to be tested performs the corresponding action.
[0037] The external interface module includes an open command interface, a close command interface, an open feedback interface, and a close feedback interface. The open feedback interface and the close feedback interface of the external interface module are respectively connected to the open feedback switch and the close feedback switch of the actuator to be tested. When the type of the actuator to be tested is a dual-control actuator to be tested, the open command interface and the close command interface of the external interface module are respectively connected to the open solenoid valve control end and the close solenoid valve control end of the dual-control actuator to be tested. When the type of the actuator to be tested is a single-control actuator to be tested, the open command interface and the close command interface of the external interface module are selected and connected to the solenoid valve control end of the single-control actuator to be tested.
[0038] The logic operation module outputs the corresponding switch command to the actuator under test through the open command interface and the close command interface, and transmits the feedback signal of the actuator under test to the start indicator HR and the stop indicator HG of the human-machine interface module through the open feedback interface and the close feedback interface. When the feedback signal is received, the corresponding indicator light turns on.
[0039] A single-body debugging device for a switch-type actuator according to an embodiment of the present invention sends a command action signal from a human-machine interface module to a logic operation module. The logic operation module generates a corresponding switch command according to the input command action signal, and outputs the switch command to a single-control actuator to be tested or a dual-control actuator to be tested through an external interface module to realize the action of the actuator to be tested. After the actuator to be tested is actuated, the switch feedback switch signal of the actuator is sent to the human-machine interface module. The human-machine interface module outputs status feedback of the actuator to be tested according to the feedback signal to realize the display of the switch status on the human-machine interface module. The embodiment of the present invention can realize the single-body debugging function of the single-control actuator to be tested and the dual-control actuator to be tested. The corresponding action signal command can be displayed on the external interface module by inputting the corresponding action signal command, and the debugging process is convenient and fast.
[0040] In some embodiments, the switch actuator monomer debugging device further includes a power supply module, and the power supply module is used to provide working voltage for the logic operation module and the actuator to be tested.
[0041] Correspondingly, the external interface module includes a power connector and a power switch. The power connector is used to connect the external voltage and input the external voltage to the power module. The power module converts the external voltage into the working voltage of the logic operation module and the actuator to be tested. The power switch is used to control whether the power module is started.
[0042] When an external voltage such as AC power is connected and the power switch is pressed, the power module starts working, converts the AC power voltage into the working voltage of the actuator to be tested, and outputs the working voltage to the logic operation module, which outputs it to the actuator to be tested after logical judgment.
[0043] In one example, the mains voltage is 220V AC and the working voltage is 24V DC. The power module is the power source of the switch actuator unit debugging device, which receives 220V AC and converts it into 24V DC required for the action command and feedback display of the actuator to be tested.
[0044] In some embodiments, the logic operation module includes a switch logic unit, a first solenoid valve KV1 and a second solenoid valve KV2, the first solenoid valve KV1 includes a first normally open contact pair (31, 32), a second normally open contact pair (33, 34) and a first normally closed contact pair (35, 36), and the second solenoid valve KV2 includes a third normally open contact pair (41, 42), a fourth normally open contact pair (43, 44) and a second normally closed contact pair (45, 46).
[0045] The switch logic unit is used to enable the first solenoid valve KV1 and the second solenoid valve KV2. When the command action signal input by the human-machine interface module is an open command, the first solenoid valve KV1 is controlled to start and the second solenoid valve KV2 is controlled to stop. When the command action signal is a close command, the first solenoid valve KV1 is controlled to stop and the second solenoid valve KV2 is controlled to start.
[0046] One contact of the first normally open contact pair (31, 32) is connected to the positive pole of the power module, and the other contact is connected to a command output interface of the external interface module; one contact of the third normally open contact pair (41, 42) is connected to the positive pole of the power module, and the other contact is connected to another command output interface of the external interface module.
[0047] The normally open contact pair of the solenoid valve is in an open state when the solenoid valve is not enabled, and is in a closed state when the solenoid valve is enabled. The normally closed contact pair of the solenoid valve is in a closed state when the solenoid valve is not enabled, and is in an open state when the solenoid valve is enabled.
[0048] Through the specific configuration of the solenoid valve, precise control of the single-control and double-control actuators to be tested is achieved, which improves the execution efficiency and reliability of the switch command.
[0049] Specifically, the switch logic unit includes a first switch (63, 64), a second switch (61, 62), a third switch (53, 54), a fourth switch (51, 52), a fifth switch (11, 12), a sixth switch (13, 14), a seventh switch (21, 22) and an eighth switch (23, 24), the first switch (63, 64) and the seventh switch (21, 22) are sequentially connected in series between the positive pole of the power module and the enable end of the first solenoid valve KV1, the second normally open contact pair (33, 34) and the second normally closed contact pair (45, 46) are connected in series and then in parallel to the first switch ( The first normally closed contact pair (35, 36) and the second normally open contact pair (43, 44) are connected in series and then connected in parallel to the two ends of the third switch (53, 54). The sixth switch (13, 14) and the second switch (61, 62) are connected in series and then connected in parallel to the two ends of the eighth switch (23, 24).
[0050] Fine control of the solenoid valve is achieved through simple switch configuration. The device has a simple structure and low cost, while also improving the safety and reliability of the system.
[0051] Furthermore, the human-machine interface module includes a single-acting and double-acting switching knob SA, an on button SB1, an off button SB3, an on indicator light HR and an off indicator light HG.
[0052] The single-double-action switching knob SA is used to switch the logic operation module between a single-control state and a double-control state. When the logic operation module is in the single-control state, the fifth switch (11, 12) and the sixth switch (13, 14) are closed, and the seventh switch (21, 22) and the eighth switch (23, 24) are opened. When the logic operation module is in the double-control state, the fifth switch (11, 12) and the sixth switch (13, 14) are opened, and the seventh switch (21, 22) and the eighth switch (23, 24) are closed.
[0053] The start button SB1 is used to control the opening and closing of the first switch (63, 64) and the second switch (61, 62); when the start button SB1 is pressed, the first switch (63, 64) is closed and the second switch (61, 62) is opened; when the start button SB1 is released, the first switch (63, 64) is opened and the second switch (61, 62) is closed.
[0054] The shutdown button SB3 is used to control the opening and closing of the third switch (53, 54) and the fourth switch (51, 52); when the shutdown button SB3 is pressed, the third switch (53, 54) is closed and the fourth switch (51, 52) is opened; when the shutdown button SB3 is released, the third switch (53, 54) is opened and the fourth switch (51, 52) is closed.
[0055] One end of the indicator light HR is connected to the positive pole of the power module, and the other end is connected to an interface of the external interface module.
[0056] One end of the shutdown indicator light HG is connected to the positive pole of the power module, and the other end is connected to another interface of the external interface module.
[0057] The external interface module comprises an opening command interface, a closing command interface, an opening feedback interface and a closing feedback interface, wherein the opening command interface is connected to another contact of the first normally open contact pair (31, 32), the closing command interface is connected to another contact of the third normally open contact pair (41, 42), the opening feedback interface is connected to another end of the opening indicator light HR, and the closing feedback interface is connected to another end of the stopping indicator light HG.
[0058] Connect the open feedback interface and the close feedback interface of the external interface module to the open feedback switch and the close feedback switch of the actuator to be tested respectively. Set the corresponding open feedback switch and close feedback switch in the actuator to be tested. When the actuator to be tested is in motion, the open feedback switch is closed, the close feedback switch is disconnected, and the external interface module returns an open feedback signal to the start indicator HR, and the start indicator HR is on. When the actuator to be tested does not move, the open feedback switch is disconnected, the close feedback switch is closed, and the external interface module returns a close feedback signal to the stop indicator HG, and the stop indicator HG is on.
[0059] In this way, an intuitive operation interface is provided, so that the user can easily switch the control state, control the switch logic unit, and monitor the state of the actuator in real time.
[0060] In some embodiments, the switch logic unit further includes a first reset switch and a second reset switch, wherein the first reset switch is arranged between the seventh switch (21, 22) and the enable end of the first solenoid valve KV1, and the second reset switch is arranged between the eighth switch (23, 24) and the enable end of the second solenoid valve KV2.
[0061] Furthermore, the human-machine interface module includes a reset button SB2, and the reset button SB2 is used to control the first reset switch and the second reset switch.
[0062] Through the design of the reset button SB2, the switch actuator monomer debugging device can be quickly restored to the initial state, which is convenient for rapid resetting during the debugging process and improves the debugging efficiency.
[0063] It should be understood that the motor-type equipment involved in the present invention only involves the type whose initial state is stopped. Normally closed means that the initial state of the valve is closed, that is, it is closed without any external force; normally open means that the initial state of the valve is open, that is, it is open without any external force. Each type is tested in the initial state.
[0064] The working principle of the switch actuator monomer debugging device of the present invention is described below in combination with four types of pneumatic switch valves in a spent fuel treatment plant: double-control normally open, double-control normally closed, single-control normally open, and single-control normally closed.

[0098] The switch actuator monomer debugging device and debugging method of the embodiment of the present invention have the following beneficial effects:
[0099] The command action signal from the human-machine interface module is sent to the logic operation module. The logic operation module generates a corresponding switch command according to the input command action signal, and outputs the switch command to the single-control actuator to be tested or the dual-control actuator to be tested through the external interface module to realize the action of the actuator to be tested. After the actuator to be tested is actuated, the switch feedback switch signal of the actuator is sent to the human-machine interface module. The human-machine interface module outputs the state feedback of the actuator to be tested according to the feedback signal to realize the display of the switch state in the human-machine interface module. The embodiment of the present invention can realize the monomer debugging function of the single-control actuator to be tested and the dual-control actuator to be tested. The corresponding action signal command can be displayed in the external interface module by inputting the corresponding action signal command, and the debugging process is convenient and fast.

The logic operation module is used to realize the mutual locking of switch commands, self-holding of commands, and the realization of single-control and double-control logic in the same analog circuit and sharing one opening command, thereby realizing the detection of multiple actuators to be tested;
[0101] The reset button SB2 set on the human-machine interface module can be used to reset the switch command of the logic operation module and restore the actuator to its initial state, so as to facilitate the rapid reset of the switch actuator unit debugging device to improve the debugging efficiency.
[0102] It only requires the series and parallel connection of buttons, knobs, relays and simple switches to build the interlocking control logic. The overall structure is simple, easy to maintain, low cost and economical.
