[0035] During the performance, stage play actors are at risk of falling off the stage due to their concentration on the performance, which may result in minor injuries such as bruises and swelling of the face, or even life-threatening.
[0036] To this end, an embodiment of the present application provides a stage actor anti-fall warning device, which can reduce the risk of stage actors falling from the edge of the stage and ensure the personal safety of the actors.
[0037] In order to make the objectives, technical solutions and advantages of the present application more clear, they are described in detail below with reference to specific drawings and embodiments.
[0038] refer to Figure 1 , Figure 2 and Figure 3 The stage actor fall prevention warning device provided in the embodiment of the present application includes a stage 1 and at least one warning component arranged at the edge of the stage 1. The warning component includes a first mounting frame 10 and a second mounting frame 20, an infrared transmitter 31 arranged on the first mounting frame 10, an infrared receiver 41 arranged on the second mounting frame 20, a first single-chip computer 32 arranged on the first mounting frame 10 and electrically connected to the infrared transmitter 31, a second single-chip computer 42 arranged on the second mounting frame 20 and electrically connected to the infrared receiver 41, and an alarm 45 arranged on the second mounting frame 20 and electrically connected to the second single-chip computer 42. The infrared transmitter 31 is configured to transmit infrared rays. The infrared receiver 41 is configured to receive infrared rays. The second single-chip computer 42 is configured to control the alarm 45 to sound an alarm when a human body blocks the infrared light path. Specifically, the infrared transmitter 31 always transmits infrared rays to the infrared receiver 41. When the actor 2 approaches the edge of the stage 1, causing the human body to block the infrared light path, the second single-chip computer 42 controls the alarm 45 to sound an alarm.
[0039] refer to Figure 4 and Figure 5 In some examples, the first mounting frame 10 and the second mounting frame 20 may each include a base disposed on the stage 1, and a mounting arm detachably disposed on the base. Specifically, the first mounting frame 10 includes a first base 11 and a first mounting arm 12, and the first mounting arm 12 is used to set the infrared transmitter 31; the second mounting frame 20 includes a second base 21 and a second mounting arm 22, and the second mounting arm 22 is used to set the infrared receiver 41. In this case, the base can be reserved on the stage 1, avoiding the problem of repositioning each time it is used, which is conducive to improving convenience.
[0040] In the specific setting, the base should meet the weight requirement. For example, the weight of the base is not less than 100 kg. In this case, it can be avoided that the first mounting frame 10 and the second mounting frame 20 are moved at will, causing the infrared receiver 41 to be unable to receive infrared rays, thereby causing the early warning function to fail.
[0041] In specific settings, the base should meet the stability requirements. Figure 4 and Figure 5 As shown, for example, the base can be a solid wood base with a diameter of 40 cm and a height of 30 cm. In this case, it can be prevented that the mounting arm falls over during use, causing the infrared receiver 41 to be unable to receive infrared rays, thereby causing the early warning function to fail. In addition, the base can also be connected and fixed to the stage 1 to improve stability.
[0042] In specific settings, the mounting arm should meet the installation height requirements. Figure 4 and Figure 5 As shown, for example, the mounting arm may be a shaft rod with a diameter of 2.5 cm and a height of 80 cm, the lower end of the mounting arm is connected to the base, and the upper end is used to mount the corresponding module.
[0043] In some examples, the base may be provided with a socket, through which the base is plugged with the mounting arm. In this case, the connection between the base and the mounting arm can be easily achieved.
[0044] refer to Figure 6 and Figure 7 In some examples, the first single-chip microcomputer 32 and the second single-chip microcomputer 42 can both adopt STC12C5A60S2 single-chip microcomputers.
[0045] In some examples, both the infrared transmitter 31 and the infrared receiver 41 can use 38Khz modules. Figure 6 and Figure 7 The control line of the infrared transmitter 31 is electrically connected to the P0.2 interface of the first single-chip microcomputer 32 , and the control line of the infrared receiver 41 is electrically connected to the P0.2 interface of the second single-chip microcomputer 42 .
[0046] refer to Figure 3 In some examples, the alarm 45 may include a first alarm 45a and a second alarm 45b, and the first alarm 45a and the second alarm 45b have different alarm forms. In the case of an early warning, the second single-chip microcomputer 42 may control at least one of the first alarm 45a and the second alarm 45b to sound an alarm. In the embodiment of the present application, the second single-chip microcomputer 42 is used to control the first alarm 45a and the second alarm 45b to sound an alarm at the same time. Compared with a single alarm form, such a setting makes it easier for the actor 2 to be alerted, and is particularly suitable for a complex stage 1 environment.
[0047] In some examples, one of the first alarm 45a and the second alarm 45b can be used for sounding, and the other can be used for emitting light. For example, the first alarm 45a is used for sounding, and the second alarm 45b is used for emitting light. It should be understood that in addition to this, the first alarm 45a and the second alarm 45b can also use other alarm forms to alarm. For example, the first alarm 45a and the second alarm 45b can use jet airflow or smoke as an alarm.
[0048] In some examples, the first alarm 45a can be a SFM-27 high-decibel buzzer. Figure 7 As shown, the control line of the alarm 45 can be electrically connected to the P0.5 interface of the second single-chip microcomputer 42.
[0049] In some examples, the second alarm 45b can be an M4T warning light. Figure 7 As shown, the control line of the second alarm 45 b can be electrically connected to the P0.6 interface of the second single-chip computer 42 .
[0050] In some examples, the second single-chip microcomputer 42 can also be configured to send a blocking signal when the human body blocks the infrared light path. The first single-chip microcomputer 32 can be configured to feedback a confirmation signal after receiving the blocking signal, so that the second single-chip microcomputer 42 controls the alarm 45 to sound an alarm according to the confirmation signal. In this case, a confirmation mechanism can be established between the second single-chip microcomputer 42 and the first single-chip microcomputer 32. When the human body blocks the infrared light path, the second single-chip microcomputer 42 can first confirm and then control the alarm 45 to sound an alarm. In specific settings, the content of the confirmation signal can be whether the infrared transmitter 31 is in a working state, or whether the position and posture of the first mounting frame 10 have changed. In the embodiment of the present application, whether the infrared transmitter 31 is in a working state is used as the content of the confirmation signal. Therefore, after receiving the blocking signal, the first single-chip microcomputer 32 can be specifically configured to feedback a confirmation signal to the second single-chip microcomputer 42 when the infrared transmitter 31 is in a working state, so that the second single-chip microcomputer 42 controls the alarm 45 to sound an alarm according to the confirmation signal.
[0051] refer to Figure 2 and Figure 3 In some examples, the first single-chip microcomputer 32 may be provided with a first communication module 33 , and the second single-chip microcomputer 42 may be provided with a second communication module 43 . The first single-chip microcomputer 32 and the second single-chip microcomputer 42 may communicate specifically through the first communication module 33 and the second communication module 43 .
[0052] refer to Figure 6 and Figure 7 In some examples, the first communication module 33 and the second communication module 43 may adopt nRF24L01 modules. In specific settings, the MOSI port of the first communication module 33 may be electrically connected to the P0.3 interface of the first single-chip microcomputer 32, the MISO port of the first communication module 33 may be electrically connected to the P0.4 interface of the first single-chip microcomputer 32, the MOSI port of the second communication module 43 may be electrically connected to the P0.3 interface of the second single-chip microcomputer 42, and the MISO port of the second communication module 43 may be electrically connected to the P0.4 interface of the second single-chip microcomputer 42.
[0053] In some examples, there may be a first channel and a second channel between the first microcontroller 32 and the second microcontroller 42. Figure 6 and Figure 7 As shown, the first channel is formed between the MISO port of the first communication module 33 and the MOSI port of the second communication module 43, and the second channel is formed between the MOSI port of the first communication module 33 and the MISO port of the second communication module 43. In specific use, one of the first channel and the second channel can be used to transmit the blocking signal, and the other can be used to transmit the confirmation signal. In this case, the communication rate between the second single-chip microcomputer 42 and the first single-chip microcomputer 32 can be improved.
[0054] refer to Figure 2 and Figure 3 In some examples, the warning component may also include a laser transmitter 34 disposed on the first mounting frame 10, and a laser receiver 44 disposed on the second mounting frame 20. The laser transmitter 34 is configured to transmit laser light. The laser receiver 44 is configured to receive laser light. The first mounting frame 10 and the second mounting frame 20 are aligned when the laser receiver 44 receives the laser light. In this case, the position debugging and calibration of the first mounting frame 10 and the second mounting frame 20 can be achieved, so as to ensure the reliability of the system. In specific use, the laser transmitter 34 and the laser receiver 44 can be started only during the installation and debugging phase, or they can be used continuously during the performance.
[0055] In some examples, the laser emitter 34 may be a Ytterbium fiber laser. In a specific configuration, a control line of the laser emitter 34 is electrically connected to a P1.0 interface of the first single-chip microcomputer 32 .
[0056] In some examples, the laser receiver 44 may be a laser mini receiver. In a specific configuration, a control line of the laser receiver 44 is electrically connected to a P1.0 interface of the second single-chip microcomputer 42 .
[0057] In some examples, there may be multiple warning components, which are arranged at intervals and at different distances from the edge of the stage 1. For example, the first, second, and third warning components are arranged at 10 cm, 50 cm, and 100 cm from the edge of the stage 1, respectively. When the actor 2 blocks the light path of each warning component, the warning component in that group issues a warning. In this case, the problem of failure to issue a warning in time due to failure of individual warning components can be avoided.
[0058] In some examples, the warning contents of the alarms 45 of the multiple warning components may be different. For example, the sound frequencies and / or light colors of the alarms 45 of the multiple warning components are different.
[0059] In some examples, the first single-chip microcomputer 32 and the infrared transmitter 31, the first communication module 33, and the laser transmitter 34 can be integrated to form the first module 30. The second single-chip microcomputer 42 and the infrared receiver 41, the alarm 45, the second communication module 43, and the laser receiver 44 can be integrated to form the second module 40. In this case, it is easy to install, which is conducive to improving the system assembly efficiency.
[0060] The method of using the stage actor anti-fall warning device of the embodiment of the present application is as follows:
[0061] S1. Install the first mounting frame 10 and the second mounting frame 20 to the two ends of the edge of the stage 1 respectively, and install the first module 30 on the first mounting frame 10 and the second module 40 on the second mounting frame 20.
[0062] S2. After the installation is completed, turn on the laser transmitter 34 and the laser receiver 44, and rotate the first mounting arm 12 and the second mounting arm 22. When the laser receiver 44 receives the laser emitted by the laser transmitter 34, the first mounting frame 10 and the second mounting frame 20 are aligned, and the debugging is completed.
[0063] S3. After debugging is completed, turn on the infrared transmitter 31 and the infrared receiver 41, so that the infrared transmitter 31 always transmits infrared rays to the infrared receiver 41. When the infrared receiver 41 can receive the infrared rays emitted by the infrared transmitter 31, the second single-chip microcomputer 42 does not trigger the alarm mechanism. When the infrared receiver 41 cannot receive the infrared rays emitted by the infrared transmitter 31, the second single-chip microcomputer 42 communicates with the first single-chip microcomputer 32. After receiving the confirmation signal from the first single-chip microcomputer 32, the second single-chip microcomputer 42 triggers the alarm mechanism to control the alarm 45 to sound an alarm.
[0064] The anti-fall warning device for stage actors of the embodiment of the present application can reduce the risk of the actor 2 of the stage 1 falling from the edge of the stage 1 and ensure the personal safety of the actor 2.
