For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0028] Now, the present application will be further described with reference to the accompanying drawings of the specification.

[0029] The embodiment of the present application provides an automatic monitoring and display device for the number of personnel in a clean production area, as Figure 1 shown. The automatic monitoring and display device for the number of personnel in the clean production area includes an access monitoring sensor 100, a display 200, a microcomputer 300, an indicator light 400, a speaker 500, and a chassis 600.

[0030] As Figure 2 shown, the signal output end of the access monitoring sensor 100 is connected to the signal input end of the microcomputer 300, and the signal output end of the microcomputer 300 is connected to the signal input ends of the display 200, the indicator light 400, and the speaker 500; the microcomputer 300 is disposed inside the chassis 600, and the display 300, the indicator light 400, and the speaker 500 are disposed outside the chassis 600.

[0031] As Figure 3 shown, the access monitoring sensor 100 is disposed at the entrance and exit of the clean production area. The access monitoring sensor 100 includes a first infrared transceiver 110, a second infrared transceiver 120, and a reflector 130. The first infrared transceiver 110 and the second infrared transceiver 120 are arranged along the direction of personnel entry and exit at the entrance and exit, and the reflector 130 is arranged corresponding to the positions of the first infrared transceiver 110 and the second infrared transceiver 120 for receiving the infrared beams emitted by the first infrared transceiver 110 and the second infrared transceiver 120.

[0032] It should be noted that the display 200, the microcomputer 300, the indicator light 400, the speaker 500, etc. mentioned in this embodiment are all existing electronic components. For example, the microcomputer 300 can be assembled using a commercially available main board, processor, memory, and power supply components. The speaker 500 can be a loudspeaker device with a power of about 5W, and the display 200 can be a digital display screen or a liquid crystal display screen.

[0033] In specific implementation, according to the signals collected by the entry and exit monitoring sensor 100, the microcomputer 300 makes corresponding judgments. For example, in the initial stage, assuming the number of people in the clean production area is 0, if the signals collected by the entry and exit monitoring sensor 100 indicate that someone has entered, then the corresponding number of people is added. If someone leaves the clean production area halfway, then the corresponding number of people is subtracted. According to different clean production areas, a personnel warning value and a personnel alarm value will be set in the microcomputer 300. The personnel warning value is less than the personnel alarm value. When it shows that the actual number of people in the clean production area exceeds the personnel warning value, it means that the number of people in the clean production area is about to reach the limit. The microcomputer 300 controls the speaker 500 to give a warning. When it shows that the actual number of people in the clean production area exceeds the personnel alarm value, it means that the number of people in the clean production area has reached the limit. The microcomputer 300 controls the speaker 500 to give a warning and controls the indicator light 400 to flash for reminder.

[0034] In this embodiment, the principle of the entry and exit monitoring sensor 100 for collecting the signals of personnel entry and exit is as follows:

[0035] The first infrared transceiver 110 and the second infrared transceiver 120 continuously emit the first infrared beam and the second infrared beam. When there is no personnel entering or leaving, under the emission action of the reflector 130, the first infrared beam and the second infrared beam can be received by the first infrared transceiver 110 and the second infrared transceiver 120. When the first infrared transceiver 110 and the second infrared transceiver 120 can continuously receive the first infrared beam and the second infrared beam reflected back by the reflector 130, it is considered that there is no personnel entering or leaving. That is, when the microcomputer 300 receives the signal of the correct received beam emitted by the first infrared transceiver 110 and the second infrared transceiver 120, the microcomputer 300 does not calculate the number of personnel in the clean production area. When there is personnel entering or leaving, if the personnel are entering, then in terms of time, the first infrared beam will be blocked first, and the second infrared beam will be blocked later. When the first infrared beam or the second infrared beam is blocked, it will undergo diffuse reflection. At this time, the first infrared transceiver 110 and the second infrared transceiver 120 cannot receive the first infrared beam and the second infrared beam reflected back from the reflector 130. At this time, the microcomputer 300 calculates the number of personnel in the clean production area according to the signals fed back by the first infrared transceiver 110 and the second infrared transceiver 120. Specifically, when both the first infrared transceiver 110 and the second infrared transceiver 120 interrupt receiving an optical signal once, in the time dimension, if the first infrared transceiver 110 interrupts receiving first and then the second infrared transceiver 120 interrupts receiving, it is determined that one person has entered the clean production area, and at this time, the number of personnel in the clean production area is incremented by one; if the second infrared transceiver 120 interrupts receiving first and then the first infrared transceiver 110 interrupts receiving, it is determined that one person has entered the clean production area, and at this time, the number of personnel in the clean production area is decremented by one, thus completing the automatic monitoring of the number of personnel in the clean production area.

[0036] In some embodiments, as Figure 2 shown, the indicator light 400 includes a first color light 401, a second color light 402, and a third color light 403. The first color light 401, the second color light 402, and the third color light 403 emit lights of different colors and are turned on under the control of the microcomputer 300 for indicating the number of personnel in the clean production area.

[0037] In this embodiment, the first color lamp 401, the second color lamp 402, and the third color lamp 403 emit lights of red, yellow, and green colors respectively. For example, according to the preset personnel warning value and personnel alarm value, if the number of personnel in the current clean production area does not exceed the personnel warning value, the microcomputer 300 controls the third color lamp 403 to work to emit green light, indicating that the number of personnel in the clean production area is normal. If the number of personnel in the current clean production area reaches the personnel warning value but does not exceed the personnel alarm value, the microcomputer 300 controls the second color lamp 402 to emit yellow light, indicating that the number of personnel in the clean production area is too large. If the number of personnel in the current clean production area is greater than or equal to the personnel alarm value, the microcomputer 300 controls the first color lamp 401 to emit red light, indicating that the number of personnel in the clean production area has exceeded the standard.

[0038] In some embodiments, the chassis 600 is disposed at the entrance and exit.

[0039] In this embodiment, the chassis 600 provides an installation position for the display 200, the microcomputer 300, the indicator lamp 400, and the speaker 500. It can be designed with a hanging function and can be correspondingly hung on the door frame at the entrance and exit position.

[0040] In some embodiments, the automatic monitoring and display device for the number of personnel in the clean production area further includes a power access line 700. One end of the power access line passes through the chassis 600 and is connected to the microcomputer 300, and the other end of the power access line 700 is used to access the power supply.

[0041] In this embodiment, the power supply refers to the industrial electricity equipped in the production area. For other electrical equipment, such as the access monitoring sensor 100, the display 200, the indicator lamp 400, the speaker 500, etc., the microcomputer 300 can distribute power to them, or they can also be connected to the corresponding industrial electricity through power wiring to provide electrical energy for them. In this embodiment, an independent power supply is not equipped in the chassis 600, but the unified power distribution of the clean production area is used. This is because once the power supply of the clean production area is lost, it is meaningless for this device to work anymore, so there is no need to set an independent power supply in the chassis 600 for power supply. Of course, it can be imagined that although it is not necessary, in some embodiments, an independent power supply can be equipped in the chassis 600 to provide electrical energy supply for electronic components such as the microcomputer 300, the access monitoring sensor 100, the display 200, the indicator lamp 400, and the speaker 500.

[0042] In some embodiments, the automatic monitoring and display device for the number of personnel in the clean production area further includes a first column 800 and a second column 900. The first infrared transceiver 110 and the second infrared transceiver 120 are arranged along the direction of personnel entry and exit at the entrance and exit on the first column 800, and the reflector 130 is arranged on the second column 900. The first column 800 and the second column 900 are arranged at the entrance and exit.

[0043] In this embodiment, the first column 800 and the second column 900 serve to install the entry and exit monitoring sensor 100. The first column 800 and the second column 900 are arranged opposite to each other and there is no connection relationship between them. They serve as a carrier to assemble the first infrared transceiver 110, the second infrared transceiver 120, and the reflector 130 at the entrance and exit, for example, arranged corresponding to the entry and exit doors of the clean production area. It should be noted that when there are multiple entrances and exits in the clean production area, the first column 800 and the second column 900 equipped with the entry and exit monitoring sensor 100 should be provided at each entrance and exit.

[0044] In some embodiments, the first infrared transceiver 110 and the second infrared transceiver 120 are arranged along the direction of personnel entry and exit at the entrance and exit on the door frame 1000. The reflector 130 includes a first reflector 131 and a second reflector 132. Among them, the first reflector 131 is arranged on the door frame 1000 corresponding to the installation position of the first infrared transceiver 110 to reflect the infrared beam emitted by the first infrared transceiver 110, and the second reflector 132 is arranged on the door frame 1000 corresponding to the installation position of the second infrared transceiver 120 to reflect the infrared beam emitted by the second infrared transceiver 120.

[0045] In this embodiment, another installation method of the entry and exit monitoring sensor 100 is provided. Only as an example, taking an automatic door as an example, the automatic door is a sliding door, and the two door bodies 1010 can be controlled to slide through an electric device (not shown in the figure) to achieve opening and closing. In the field of clean production, generally only corresponding staff can enter. Therefore, the conditions for starting the electric device are generally password, fingerprint, radio frequency identification, etc. Therefore, an identifier 1020 is provided on the automatic door. After the identifier 1020 identifies the corresponding identity, such as password authentication passing, fingerprint authentication passing, radio frequency identification code scanning passing (such as swiping a work permit), the automatic door opens. When a person enters, the infrared beams emitted by the first infrared transceiver 110 and the second infrared transceiver 120 will be blocked in sequence, thereby realizing the acquisition of the person's entry and exit signals. Among them, the first infrared transceiver 110 and the first reflector 131 are correspondingly arranged on the door frame 1000 corresponding to the entrance side, and the second infrared transceiver 120 is correspondingly arranged on the door frame 1000 corresponding to the exit side. This installation method is particularly suitable for this type of automatic sliding door because the opening and closing method of this type of door will not interfere with the infrared beam, and thus will not cause mis-acquisition of the person's entry and exit signals. If it is a door body installed with a traditional door leaf, if the entry and exit monitoring sensor 100 is to be assembled on the door frame, the opening direction of the door body should be considered to ensure that the opening of the door body will not block the infrared beam emitted by the entry and exit monitoring sensor 100.

[0046] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should all be covered by the scope of the claims and the description of the present application.
