[0002] During the actual use of laboratory workstations, it is common for lab workers to lack safety awareness, fail to promptly disconnect the power supply after the experiment, or leave the lab without authorization. During this time, some equipment and tools that could become heat sources continue to operate, causing the temperature to rise, leading to spontaneous combustion or the combustion of surrounding flammable materials. For example, soldering irons, heat guns, and latex guns are commonly used in electrical engineering experiments, and electric heating furnaces are commonly used in chemical and biological experiments. These heat sources are highly susceptible to fires when operating for extended periods of time. In addition to relying on the establishment of laboratory management systems and the enhancement of lab workers' safety awareness, the development of artificial intelligence can enable the use of innovative technologies to more effectively manage the power supply to these heat source devices, thereby more reliably ensuring the safety of laboratory personnel and objects.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] The embodiment of the present invention discloses a power management system for an experimental operation table based on face recognition, which is used to control the on and off of the power supply of the socket 6 on the experimental operation table. Figure 1 As shown, it includes: a switching power supply 4, an industrial computer 1, and a serial port relay 5;

[0037] The switching power supply 4 is electrically connected to the industrial computer 1 and the serial port relay 5 respectively, and is used to supply power to the industrial computer 1 and the serial port relay 5;

[0038] The industrial computer 1 includes a camera 2 and a controller, wherein the camera 2 is connected to the controller to obtain the facial information of the current person and send the facial information to the controller. The controller is connected to the serial port relay 5 to receive the facial information to complete facial recognition and send a serial communication instruction to the serial port relay 5 after successful facial recognition.

[0039] The serial port relay 5 is also electrically connected to the socket 6 and is used to control the corresponding relay to be turned on according to the serial port communication instruction, thereby supplying power to the socket 6.

[0040] In order to further implement the above technical solution, the industrial computer 1 also includes a touch screen, which is connected to the controller. The controller receives the control command received by the touch screen and sends the corresponding serial communication instruction to the serial relay 5 according to the control command.

[0041] In order to further implement the above technical solution, a server is also included, and the server includes a socket 6 usage storage unit and an experimenter face information database and is used to store the socket 6 usage and the experimenter's face information respectively; the socket 6 usage storage unit and the experimenter face information database are both connected to the industrial computer 1.

[0042] In order to further implement the above technical solution, the industrial computer 1 also includes a timer, which is connected to the controller and is used to count the usage time of the socket 6 and send the timing data to the server;

[0043] The server also includes a socket 6 available time storage unit and a comparator;

[0044] The time storage unit is connected to the comparator, which is used to store the preset available time of each socket 6 of the experimental bench. The comparator is used to receive the timing data of the timer, compare the timing data with the preset available time, and send the comparison result to the controller, which assists the controller in sending corresponding serial communication instructions to the serial relay 5.

[0045] In order to further implement the above technical solution, the switching power supply 4 is connected to the industrial computer 1 and the serial port relay 5 respectively through the DC power line 3, the serial port relay 5 is connected to the industrial computer 1 through the serial port to USB cable 7, and the serial port relay 5 is connected to the live wire of each socket 6.

[0046] It should be noted that:

[0047] The serial relay 5 is inserted into the USB port of the industrial computer 1 through the serial-to-USB cable 7. The industrial computer 1 system automatically generates a COM port. The industrial computer 1 sends serial communication instructions to the serial relay 5 through the COM port connected to the serial relay 5.

[0048] A power management method for an experimental operation table based on face recognition is used to control the on and off of the power supply of the socket 6 on the experimental operation table. Figure 3 As shown, the following steps are included:

[0049] S1. The switching power supply 4 supplies power to the industrial computer 1 and the serial relay 5. The industrial computer 1 controls the camera 2 to obtain the current personnel's facial information, completes face recognition based on the facial information, and after successful face recognition, sends a serial communication command to the serial relay 5;

[0050] S2. The serial port relay 5 controls the corresponding relay to conduct according to the serial port communication instruction, thereby supplying power to the socket 6.

[0051] In order to further implement the above technical solution, the specific content of sending the serial communication instruction to the serial port relay 5 in S1 includes:

[0052] The touch screen receives the control command of the current experimenter and sends the corresponding serial communication instruction to the serial port relay 5 according to the control command.

[0053] In order to further implement the above technical solution, the face recognition process in S1 includes obtaining the face information of the current person and matching it with the face information already in the experimenter face information database. If the experimenter face information database includes the current face information, the face recognition is successful.

[0054] S2 also includes storing the usage of the socket 6 .

[0055] In order to further implement the above technical solution, the following steps are also included:

[0056] Count the usage time of the socket 6, compare the timing data with the preset available time, and send the corresponding serial communication command to the serial port relay 5 according to the comparison result;

[0057] If the timing data is greater than or equal to the preset available time, a serial port communication closing instruction is sent to the serial port relay 5.

[0058] In order to further implement the above technical solution, the following steps are also included:

[0059] In S1 , the switching power supply 4 converts AC power into DC power to supply power to the industrial computer 1 and the serial port relay 5 .

[0060] It should be noted that:

[0061] The switching power supply 4 may also be a power adapter, both of which are used to convert 220V AC power into DC power (usually 12V).

[0062] The serial port relay 5 may be a multi-channel serial port relay.

[0063] like Figure 2 As shown, the industrial computer 1 can be installed on the hanging plate rack of the experimental operation table, or fixedly installed through the support arm rack.

[0064] The industrial computer 1 can use Windows system or Android system.

[0065] The control management system software deployed in the controller of the industrial computer 1 can be remotely accessed and controlled via the network, and has great scalability in function. The usage of the power supply of each socket 6 can be saved on the server and can be used for future investigation and analysis of accidents and failures.

[0066] The working principle of this embodiment will be further described below:

[0067] Industrial computer 1 is equipped with camera 2. Its controller is installed with control and management system software, which has facial recognition capabilities. Laboratory managers pre-enter the facial information of laboratory personnel. When a laboratory personnel needs to use a laboratory workstation, they face camera 2 on industrial computer 1. Once the software recognizes the personnel, they are granted access to power socket 6 on the workstation.

[0068] On the control management system software interface of the industrial computer 1, there is a button icon corresponding to the power supply of socket 6. When the experimenter needs to use a certain socket 6, he clicks the corresponding button icon. The software sends a serial communication instruction to the serial relay through the COM port connected to the serial relay, so that the power supply of the socket 6 can be connected, and the experimenter can use the power supply of the socket 6.

[0069] Taking a certain type of serial port relay 5 as an example, the serial port communication instructions for each channel are as follows:

[0070]

[0071] After successfully recognizing the facial information, the control and management system software opens the serial communication function of the COM port. When the experimenter clicks the button corresponding to the first socket 6 on the software interface, assuming that the socket 6 is connected to the first line of the relay, the hexadecimal communication instruction "01 05 00 00 FF 00 8C 3A" is sent to connect the first line of the relay, and the first socket 6 is thus powered on, and the power supply of the socket 6 can be used.

[0072] After the power supply is used up, the experimenter clicks the button corresponding to the first socket 6 on the software interface again. Assuming that the socket 6 is connected to the first line of the relay, the hexadecimal communication command "01 05 00 00 00 00 CD CA" is sent to disconnect the first line of the relay, and the power supply to the first socket 6 is cut off.

[0073] The experimental manager can set the available time of each experimental operation table socket 6 in the server-side software in the control management system. If the time is exceeded, the control system can send an instruction to turn off the power of the socket 6. This prevents the experimenter from leaving the experimental operation table without turning off the power.

[0074] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. Reference can be made to the common and similar parts between the various embodiments. For the devices disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple, and the relevant parts can be referred to the method description.

[0075] The above description of the disclosed embodiments is intended to enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
