[0032] Embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0033] Figure 1is a block diagram illustrating a test device 100 according to an embodiment of the present disclosure.

[0034] Referring to Figure 1 The test device 100 can be used to detect within a certain range when various tests are performed on a test object (hereinafter, also simply referred to as an object) T. According to an embodiment of the present disclosure, the test device 100 can be used to secure safety of a person during a test, in addition to being used to perform various tests on the test object T. According to an embodiment of the present disclosure, the test device 100 can include a test platform 110 and a plurality of guards 120.

[0035] In one embodiment, the test object T can be a wind turbine generator or a component constituting a wind turbine. The test platform 110 can be a test platform for a wind turbine generator, or a test platform for testing a certain component in a wind turbine. However, the present disclosure is not limited thereto. For example, the test platform 110 can be a test platform for various devices.

[0036] The guard (or safety guard) 120 can be a device that separates an object (for example, the test object T) having a potential danger from the outside in the form of a shield, a cover, a fence, a box, a barrier, etc. in order to prevent or avoid an electric safety risk or a mechanical safety risk (for example, to prevent contact with or excessive approach to a dangerous object). The plurality of guards 120 can be disposed at intervals from each other around the test platform 110, and can be connected to the test platform 110. Accordingly, the test platform 110 can be separated from the outside by the plurality of guards 120 to avoid a safety risk.

[0037] According to an embodiment of the present disclosure, the plurality of guards 120 can detect whether an object (for example, a person who is not related to a test operation) approaches the test object T using a non-contact detection method. Accordingly, the test device 100 including the plurality of guards 120 can reduce the laying of a cable and improve the versatility and mobility of the device, thereby being applicable to various types and / or various numbers of test objects T.

[0038] The non-contact detection method can include infrared detection, grating detection, ultrasonic detection, etc. In one preferred embodiment, the present disclosure can use an infrared detection method. Accordingly, the test device 100 can have the advantages of convenience and low cost.

[0039] Infrared detection can be classified into active infrared detection and passive infrared detection. Active infrared detection can mean that a transmitter for emitting an infrared signal is provided at one end, and a receiver for receiving the emitted infrared signal is provided at the other end. When the receiver does not receive the infrared signal, it means that the infrared signal is blocked (for example, a worker enters), thereby triggering an alarm. Passive infrared detection can mean that whether a worker enters a test area is determined by detecting infrared radiation emitted by an object itself (i.e., the temperature of the object affects the properties of infrared light radiated by the object), thereby triggering an alarm. In one embodiment, the present disclosure can employ the detection method of active infrared detection. Accordingly, the test device 100 has a high detection accuracy and a low false trigger rate.

[0040] In the case of employing the detection method of active infrared detection, according to an embodiment of the present disclosure, at least one infrared light path 130 can be established between the plurality of shields 120 and can separate the test platform 110 from the outside, and the plurality of shields 120 can be connected to each other through the at least one infrared light path 130. Each of the at least one infrared light path 130 can include an infrared signal. When an object passes through the infrared signal in the infrared light path 130, the object reflects or absorbs at least a portion of the infrared signal, so that the infrared signal received by the receiver for receiving the infrared signal is changed. Accordingly, whether a worker enters a test area can be determined by detecting a change in the infrared signal. In one embodiment, the at least one infrared light path 130 can form a closed structure so that the test platform 110 is surrounded in the closed structure. In another embodiment, the at least one infrared light path 130 can not form a closed structure, but can form a closed structure as a whole together with the surrounding environment so that the test platform 110 is surrounded in the closed structure.

[0041] Accordingly, the test device 100 according to an embodiment of the present disclosure can determine whether a worker enters a closed structure from the outside, thereby triggering an alarm. The test device 100 according to an embodiment of the present disclosure improves the safety of the test process, and also has high convenience because the test device 100 can be moved, thereby being suitable for safety protection for various types and / or various numbers of test objects.

[0042] Figure 2 is a block diagram illustrating one shield 120 in the test device 100 according to an embodiment of the present disclosure.

[0043] Referring to Figure 2According to an embodiment of the present disclosure, each of the plurality of shields 120 can include an infrared emitter 1201 and / or an infrared receiver 1202. In one example, each of the infrared emitter 1201 and the infrared receiver 1202 can be a multi-beam pair infrared detector, such that the infrared emitter 1201 can implement emission of infrared signals in a specific direction, and the infrared receiver 1202 can implement reception of infrared signals in a direction perpendicular thereto at the same time.

[0044] The infrared emitter 1201 can face another shield of the plurality of shields 120 to establish and connect to a first infrared light path 131 of the at least one infrared light path 130. The infrared receiver 1202 can face another shield of the plurality of shields 120 to establish and connect to a second infrared light path 132 of the at least one infrared light path 130. In one embodiment, when each of the plurality of shields 120 includes both an infrared emitter and an infrared receiver, the first infrared light path 131 can be different from the second infrared light path 132.

[0045] Optionally, according to an embodiment of the present disclosure, each of the plurality of shields 120 can further include a support device 1203. The infrared emitter 1201 and / or the infrared receiver 1202 can be fixed to the support device 1203, respectively, and the support device 1203 can be used to support the infrared emitter 1201 and / or the infrared receiver 1202. In addition, the support device 1203 can be stably placed on the ground.

[0046] Therefore, when a person enters the test interval in any direction (for example, enters the enclosed structure by passing through the infrared light path), the infrared light path in the direction is blocked, and the corresponding infrared receiver 1202 issues an alarm signal due to the failure to detect the infrared signal, prompting the test personnel to check the surrounding environment.

[0047] According to an embodiment of the present disclosure, the infrared receiver 1202 can have a self-resetting function. Therefore, it can be avoided that the test operator actively finds which of the plurality of infrared receivers 1202 triggers the alarm, thereby reducing the operation complexity of the test operator.

[0048] In addition, in one embodiment, the test device 100 can include a temporary access switch. When the temporary access switch is opened, the test device 100 can allow other professional detection personnel to temporarily pass through the infrared light path 130 within a short time, thereby improving convenience under the premise of ensuring safety.

[0049] Figure 3 is a block diagram illustrating a first embodiment of the test device 100 including two shields according to an embodiment of the present disclosure.

[0050] Referring to Figure 3The plurality of shields 120 can include a first shield 121 and a second shield 122. In one embodiment, the first shield 121 can include a first infrared emitter 1211, and the second shield 122 can include a second infrared receiver 1222. The first infrared emitter 1211 and the second infrared receiver 1222 can face each other, can establish a first infrared light path 131, and can be connected to each other through the first infrared light path 131.

[0051] Therefore, when a person passes through the first infrared light path 131, the first infrared light path 131 is blocked, the second infrared receiver 1222 issues an alarm signal due to the detection of no infrared signal, reminding the test personnel to check the surrounding environment.

[0052] Figure 4 is a block diagram illustrating a second embodiment of the test device 100 including three shields according to an embodiment of the present disclosure.

[0053] Referring to Figure 3 and Figure 4 The plurality of shields 120 can further include a third shield 123. In one embodiment, the first shield 121 can further include a first infrared receiver 1212, and the third shield 123 can include a third infrared emitter 1231. The third infrared emitter 1231 and the first infrared receiver 1212 can face each other, can establish a second infrared light path 132, and can be connected to each other through the second infrared light path 132.

[0054] Therefore, when a person passes through the first infrared light path 131 and / or the second infrared light path 132, the first infrared light path 131 and / or the second infrared light path 132 is blocked, the first infrared receiver 1212 and / or the second infrared receiver 1222 issues an alarm signal due to the detection of no infrared signal, reminding the test personnel to check the surrounding environment.

[0055] In one embodiment, the second shield 122 can further include a second infrared emitter 1221, and the third shield 123 can further include a third infrared receiver 1232. Remaining infrared light paths in the at least one infrared light path 130, other than the first infrared light path 131 and the second infrared light path 132, can be established between the second shield 122 and the third shield 123. The first infrared light path 131, the second infrared light path 132, and the remaining infrared light paths can form a closed structure, such that the test platform 110 is enclosed within the closed structure.

[0056] Therefore, when a person passes through at least one of the first infrared light path 131, the second infrared light path 132, and the remaining infrared light path to enter the enclosed structure, at least one of the first infrared light path 131, the second infrared light path 132, and the remaining infrared light path is blocked, and at least one of the first infrared receiver 1212, the second infrared receiver 1222, and the third infrared receiver 1232 issues an alarm signal due to the failure to detect the infrared signal, reminding the tester to check the surrounding environment.

[0057] However, it should be understood that the present disclosure is not limited thereto. For example, the plurality of shields 120 can include more shields as needed, and more infrared light paths can be established as needed, and the enclosed structure can or can not be formed through the infrared light paths as needed.

[0058] Figure 5 is a block diagram illustrating an infrared receiver 1202 according to an embodiment of the present disclosure.

[0059] Referring to Figure 5 , the infrared receiver 1202 can include an infrared signal receiving terminal IR and an alarm signal transmitting terminal AT. According to an embodiment of the present disclosure, the infrared signal receiving terminal IR can be connected to the second infrared light path 132 to receive the infrared signal IS through the second infrared light path 132. The alarm signal transmitting terminal AT can be connected to the test platform 110 to transmit the alarm signal AS indicating that the second infrared light path 132 is blocked to the test platform 110.

[0060] Referring to Figure 5 , the test platform 110 can include an alarm signal receiving terminal AR, an alarm module 111, and a test execution module 112. According to an embodiment of the present disclosure, the alarm signal receiving terminal AR can be connected to the alarm signal transmitting terminal AT to receive the alarm signal AS from the alarm signal transmitting terminal AT. The alarm module 111 can be connected to the alarm signal receiving terminal AR and can be used to output a test stop signal SS indicating to stop the test and a control signal for performing an audible and visual alarm. The test execution module 112 can be connected to the alarm module 111 to receive the test stop signal SS from the alarm module 111. According to an embodiment of the present disclosure, the stop signal SS can be transmitted to the test execution module 112 so that the test execution module 112 stops acting or stops the job flow to ensure the safety of the workers and equipment.

[0061] In one embodiment, the alarm signal transmitting terminal AT and the alarm signal receiving terminal AR can be communicatively connected to each other in a wireless manner. In this way, the laying of cables can be reduced, and the versatility and mobility of the equipment can be improved.

[0062] Figure 6 is a diagram illustrating the alarm signal receiving terminal AR and the alarm module 111 according to an embodiment of the present disclosure.

[0063] Referring to Figure 5 and Figure 6 , the alarm module 111 can include a first circuit SC1 and a second circuit SC2. The first circuit SC1 can include a first switch SW1, a relay R, and a control module C, and the second circuit SC2 can include a second switch SW2 and an alarm A. Also, the first switch SW1 can be disposed in the alarm signal receiving terminal AR.

[0064] According to an embodiment of the disclosure, the first switch SW1 can be in a normally closed state, and the closing and opening of the first switch SW1 can be controlled by the alarm signal receiving terminal AR. When the light path is not blocked and the alarm signal receiving terminal AR does not receive the alarm signal AS, the first switch SW1 can be in a closed state, the data input channel DI receives a signal indicating that the first switch SW1 is closed, and a processor (e.g., a central processing unit (CPU), etc.) in the control module can control the output of the data output channel DO (e.g., reset the data output channel DO) so that the relay R does not work. When the light path is blocked and the alarm signal receiving terminal AR receives the alarm signal AS, the first switch SW1 is controlled to be open, the data input channel DI can receive a signal indicating that the first switch SW1 is open, and the processor in the control module can control the output of the data output channel DO (e.g., set the data output channel DO) so that the relay R starts to work.

[0065] According to an embodiment of the disclosure, the second switch SW2 can be in a normally open state, and the closing and opening of the second switch SW2 can be controlled by the relay R. When the relay R does not work, the second switch SW2 is in an open state, and the alarm A does not work. When the relay R works, the relay R closes the second switch SW2 so that the alarm A can work.

[0066] In one embodiment, after the processor in the control module controls the data output channel DO to be set, the data output channel DO can not be automatically reset. Therefore, the detection personnel can manually reset after checking and confirming that there is no safety risk, thereby turning off the alarm A.

[0067] Therefore, the test device 100 according to an embodiment of the disclosure can set the infrared receiver 1202 to have a self-reset function and set the alarm module 111 to not have an automatic reset function, and thus safety and convenience can be improved.

[0068] In addition, in one embodiment, the alarm can be additionally included in the infrared receiver 1202 in addition to being included in the alarm module 111 of the test platform 110. In this case, even if the alarm module 111 of the test platform 110 fails, the alarm can be performed by the alarm in the infrared receiver 1202 in order to ensure safety.

[0069] The utility model discloses the detection mode of active infrared detection is applied to the protection of detection device, therefore, test device 100 can be convenient for moving and setting to be applicable to various types and / or various quantity's test object T, has the advantage that convenience is high and cost is low. In addition, test device 100 according to the embodiment of the disclosure can set infrared receiver 1202 to have the self-resetting function and set alarm module 111 to not have the automatic reset function, and therefore can improve the safety and convenience.

[0070] Although the utility model has been specifically shown and described with reference to its exemplary embodiments, it will be understood by those skilled in the art that various changes in form and details can be made thereto without departing from the spirit and scope of the utility model as defined by the claims.
