These terms are only used to distinguish one element or data from another. For example, without departing from the scope of this application, a first alarm message may be referred to as a second alarm message, and similarly, a second alarm message may be referred to as a first alarm message. Both the first alarm message and the second alarm message are alarm messages, but they are not the same alarm message.

[0044] It is understood that the term "connection" in the following embodiments should be understood as "electrical connection," "communication connection," etc., if the connected circuits, modules, units, etc., have electrical signal or data transmission with each other.

[0045] It is understandable that "multiple" refers to two or more. "At least part of an element" refers to part or all of an element.

[0046] When used herein, the singular forms of “a,” “an,” and “the” may also include the plural forms unless the context clearly indicates otherwise. It should also be understood that the terms “comprising,” “including,” or “having,” etc., specify the presence of the stated feature, whole, step, operation, component, part, or combination thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof.

[0047] In one embodiment, such as Figure 1 As shown, an electrical testing system 10 is provided, including an electrical testing device 102 and an electronic key 104.

[0048] The electrical testing equipment 102 is equipped with an information acquisition and communication port 1022, which is used to connect to the circuit to be tested.

[0049] The electronic key 104 is connected to the lock. The electronic key 104 is used to connect to the power testing equipment 102 through the information acquisition communication port 1022. The lock is used to lock the energy isolation point of the circuit to be tested.

[0050] Electronic key 104 is used for:

[0051] In response to the encoding acquisition operation, the built-in encoding of the information acquisition communication port 1022 is acquired.

[0052] Obtain the voltage testing results from voltage testing equipment 102.

[0053] If the voltage test result shows no power, read the lock's operation code.

[0054] The lock is allowed to be opened if the operation code of the lock is the same as the built-in code of the information collection communication port 1022.

[0055] The voltage testing device 102 is used to check whether the circuit to be tested is energized, ensuring the safety of operators. After the voltage test is passed, i.e., the circuit to be tested is de-energized, the lock can be opened to lock the switch or knife switch in the open position, preventing accidental closing or misoperation, thus ensuring safety. Furthermore, the lock can be used in conjunction with a grounding wire to improve the reliability of grounding.

[0056] The built-in code of the information acquisition communication port 1022 can correspond one-to-one with the circuit to be tested. The voltage testing device 102 can acquire and determine the operation code of the connected circuit to be tested, and then output the operation code of the circuit to be tested to the electronic key 104. That is, the operation code of the circuit to be tested determined by the voltage testing device 102 based on the connected circuit is the built-in code of the information acquisition communication port 1022. When the electronic key 104 is inserted into the information acquisition communication port 1022, the electronic key 104 can connect with the voltage testing device 102, thereby obtaining the voltage testing result of the voltage testing device 102. If the power test result shows no power, the electronic key 104 can read the lock's operation code. If the lock's operation code matches the built-in code of the information collection and communication port 1022, the electronic key 104 is deemed authorized to open the lock, and the operator is allowed to open the lock. If the lock's operation code does not match the built-in code of the information collection and communication port 1022, the electronic key 104 is deemed not authorized to open the lock, and the operator is prohibited from opening the lock.

[0057] The built-in code of the information acquisition communication port 1022 can correspond one-to-one with the operation code of the lock. The voltage testing device 102 performs voltage testing on the connected circuit to be tested, and outputs the corresponding voltage testing result to the electronic key 104. In response to the code acquisition operation, the electronic key 104 directly acquires the built-in code of the information acquisition communication port. When the electronic key 104 is inserted into the information acquisition communication port 1022, the electronic key 104 can connect with the voltage testing device 102, thereby obtaining the voltage testing result of the voltage testing device 102. If the power test result shows no power, and the electronic key 104 considers the information collection and communication port 1022 to correspond to the lock if the operation code of the lock matches the built-in code of the information collection and communication port 1022, then the electronic key 104 connected to the information collection and communication port 1022 is authorized to open the lock, and therefore, the operator is allowed to open the lock. If the operation code of the lock does not match the built-in code of the information collection and communication port 1022, then the electronic key 104 connected to the information collection and communication port 1022 is not authorized to open the lock, and therefore, the operator is prohibited from opening the lock.

[0058] Therefore, the aforementioned voltage detection system 10 includes a voltage detection device 102 and an electronic key 104. The electronic key 104 responds to an encoding acquisition operation and the built-in encoding of the information acquisition communication port 1022. If the voltage detection result is no power, it reads the lock's operation code. Only if the lock's operation code matches the built-in encoding of the information acquisition communication port 1022 is the lock allowed to be opened. Based on this voltage detection system 10, operators can perform operations while carrying only the electronic key 104, greatly facilitating staff and reducing the use of various cumbersome tools in traditional technologies. Furthermore, this voltage detection system 10 only allows staff to open the lock if the voltage detection result of the circuit to be tested is no power and the electronic key 104 is authorized to open the lock, thus improving operational safety and significantly reducing the possibility of misoperation.

[0059] In one embodiment, the electronic key 104 is also used to generate and output a first alarm message if the voltage test result is positive.

[0060] If the voltage test result shows that there is electricity, the voltage test fails. At this time, the matching step between the lock's operation code and the built-in code of the information acquisition communication port 1022 is not performed. Instead, the first alarm message is directly output to warn the operator that the circuit to be tested has failed the voltage test, taking into account both energy consumption and operational safety.

[0061] Furthermore, the first alarm message can be implemented by outputting audible and visual alarm signals based on the audible and visual alarm module. The first alarm message can also be implemented by sending alarm information to the operator's terminal and / or monitoring terminal based on the communication module. This alarm message can be a pop-up window carrying alarm data, or it can be an SMS message carrying alarm data.

[0062] In one embodiment, the electronic key 104 is also used to generate and output a second alarm message when it receives an encoding acquisition operation and does not receive a voltage verification result within a preset time period.

[0063] If an encoding acquisition operation is received and no voltage test result is received within a preset time period, it indicates a voltage test failure. At this time, the electronic key 104 generates and outputs a second alarm signal to remind the operator that there is a problem with the voltage test system 10 and that maintenance is required, thereby ensuring the timeliness of maintenance.

[0064] Similar to the first alarm message, the second alarm message can also be implemented by outputting audible and visual alarm signals based on the audible and visual alarm module. The second alarm message can also be implemented by sending alarm information to the operator's terminal and / or the monitoring terminal based on the communication module. This alarm message can be a pop-up window carrying alarm data or an SMS message carrying alarm data.

[0065] In one embodiment, the electronic key 104 is an electronic key 104 carrying a display module.

[0066] The display module can display the data from the electronic key 104. Specifically, after the electronic key 104 is inserted into the information acquisition communication port 1022, it can respond to the encoding acquisition operation of the display module to obtain the built-in encoding of the information acquisition communication port 1022, which can be displayed on the display module. Correspondingly, the voltage detection result obtained by the electronic key 104 can also be displayed on the display module to improve the visualization of the voltage detection system 10.

[0067] Furthermore, the matching result between the lock operation code executed by the electronic key 104 and the built-in code of the information collection communication port 1022 can also be displayed on the display module, so that the operator can intuitively determine that the lock is prohibited from being opened due to code mismatch.

[0068] Therefore, operators can execute work procedures based on the display module on the electronic key 104. Specifically, if the lock is not powered on, the display module will show "Power not tested, please test power," and the electronic key 104 is not authorized to open the lock. If the electronic key 104 receives a code acquisition operation but does not receive a power test result within a preset time period, the display module will show "Power test failed," and the electronic key 104 is not authorized to open the lock. If the power test result is positive, the display module will show "Power on! Lock opening prohibited!" and the electronic key 104 is not authorized to open the lock. If the power test result is negative, the display module will show "No power," and the electronic key 104 is not authorized to open the lock. If the power test result is negative, and the lock's operation code matches the built-in code of the information acquisition communication port 1022, the display module will show "Safe, lock can be opened," and the electronic key 104 is authorized to open the lock.

[0069] In one embodiment, the display module is an OLED (Organic Light-Emitting Diode) screen.

[0070] In one embodiment, such as Figure 2 , Figure 3 and Figure 5 As shown, the voltage testing device 102 includes: a housing 1024 and a three-phase voltage testing circuit.

[0071] The housing 1024 has an accommodating space, in which the information acquisition and communication port 1022 is located on the outer wall of the housing 1024.

[0072] The input terminal of the three-phase voltage detection circuit is used to connect to the circuit to be tested, and the output terminal of the three-phase voltage detection circuit is connected to the information acquisition communication port 1022.

[0073] When all phases of the relays in the circuit under test are engaged, the three-phase voltage detector outputs a voltage test result of no voltage; when any phase of the relays in the circuit under test is disengaged, the three-phase voltage detector outputs a voltage test result of voltage. The information acquisition communication port 1022 is connected to both the output terminal of the three-phase voltage detector and the electronic key 104. Therefore, the electronic key 104 can read the three-phase status of the voltage detector 102 through the information acquisition communication port 1022, thereby obtaining the voltage test result of the voltage detector 102.

[0074] In one embodiment, such as Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, the electrical testing equipment 102 also includes a three-phase indicator light 1026.

[0075] The three-phase indicator light 1026 is connected to the three-phase voltage testing circuit, and the three-phase indicator light 1026 is located on the outer wall of the housing 1024; the three-phase indicator light 1026 is used to turn off when the voltage testing circuit is de-energized.

[0076] Correspondingly, if the voltage test result shows that there is power, the three-phase indicator light 1026 will light up.

[0077] In one embodiment, there are three three-phase indicator lights 1026, each corresponding to one of the three phases of the relay. Specifically, when all phases of the relay in the circuit to be tested are engaged, the three-phase power testing circuit outputs a power test result of no power, and all three three-phase indicator lights 1026 are off; when any phase of the relay in the circuit to be tested is disengaged, the three-phase power testing circuit outputs a power test result of power, and the three-phase indicator light 1026 corresponding to the energized phase lights up.

[0078] In one embodiment, such as Figure 2 and Figure 6 As shown, the voltage detection system 10 also includes a three-phase voltage detection port 1028.

[0079] The three-phase voltage test hole 1028 is connected to the three-phase voltage test circuit, and the three-phase voltage test hole 1028 is located on the outer wall of the housing 1024.

[0080] Based on the three-phase voltage test port 1028, operators can perform voltage testing using traditional methods, so that even if the electronic key 104 malfunctions, the voltage test results can still be obtained, thus improving the reliability of the voltage testing system 10.

[0081] In one embodiment, the number of three-phase voltage test holes 1028 can be three, each corresponding to one phase of the three-phase relay.

[0082] In one embodiment, such as Figure 2 , Figure 5 , Figure 6 , Figure 7 , Figure 8 ,and Figure 9 As shown, the housing 1024 includes: a panel 1024a, a middle frame 1024b, and a back cover 1024c.

[0083] The information acquisition and communication port 1022 is fixed to the outer surface of the panel 1024a by screws.

[0084] The middle frame 1024b and the panel 1024a are engaged with each other through a snap-fit ​​structure 1030.

[0085] The back cover 1024c and the middle frame 1024b are fitted together by screws.

[0086] The panel 1024a, the middle frame 1024b, and the back cover 1024c work together to form an accommodating space.

[0087] The back of the information acquisition and communication port 1022 is fixed to the panel 1024a with screws. Multiple three-phase indicator lights 1026 are inserted into the three-phase voltage detection circuit through the panel 1024a and then snapped in place by the snap-fit ​​structure 1030 to fix the middle frame 1024b and the panel 1024a. Then, the back cover 1024c is fixedly connected to the middle frame 1024b with screws.

[0088] In one embodiment, such as Figure 5 and Figure 10 As shown, the back cover 1024c has a cutout area that matches the shape of the voltage testing circuit board 1032; wherein, the voltage testing circuit board 1032 is the circuit board where the three-phase voltage testing circuit is located.

[0089] The cutout area matches the shape of the voltage testing circuit board 1032 to prevent contaminants from entering the accommodating space through the gap between the voltage testing circuit board 1032 and the back cover 1024c.

[0090] In one embodiment, the voltage testing circuit board 1032 may be a PCB (Printed Circuit Board).

[0091] In one embodiment, such as Figure 5 and Figure 10 As shown, a support component is soldered to the back of the voltage testing circuit board 1032.

[0092] The support component can support the voltage testing circuit board 1032 when the voltage testing equipment 102 is in normal use, thereby reducing the shaking of the voltage testing circuit board 1032 and avoiding poor circuit contact caused by the shaking of the voltage testing circuit board 1032, thus improving the stability of the voltage testing system 10.
