Description

Technical Field

[0001] The utility model relates to the field of gas concentration, in particular to a wireless carbon dioxide concentration real-time monitoring device. Background Art

[0002] Currently, many laboratories (such as experimental animal rooms) and experimental equipment need to monitor the carbon dioxide concentration inside them in real time. Patent announcement document CN204330727U discloses a carbon dioxide concentration monitoring instrument. This detector monitors the carbon dioxide concentration by fixing a carbon dioxide concentration sensor (numbered 9 in the document) in a waterproof shell (numbered 1 in the document). However, the monitoring reliability of this detector is too poor for laboratories. Because the molecular weight of carbon dioxide is 44, and the average molecular weight of air is 29, the density of carbon dioxide is greater than that of air. Therefore, in a space with poor gas circulation such as a laboratory, carbon dioxide gas is easy to accumulate in a corner, and this measuring instrument can only measure the carbon dioxide concentration at the place where it is fixed. Therefore, a measuring instrument with this structure cannot accurately measure the carbon dioxide concentration in the laboratory. Utility Model Content

[0003] In view of the above problems, the present invention proposes a wireless real-time monitoring device for carbon dioxide concentration. The device adopts multiple carbon dioxide concentration probes for monitoring, thereby improving the reliability of detection.

[0004] The technical solutions adopted by this utility model are as follows:

[0005] A wireless real-time carbon dioxide concentration monitoring device includes a shell and a control mainboard, the control mainboard is arranged in the shell, and also includes several carbon dioxide concentration probes and an antenna. The outer wall of the shell is provided with several data line interfaces, the data line interfaces are connected to the control mainboard, and the carbon dioxide concentration probes are connected to the data line interfaces via data lines. The antenna is arranged on the outer wall of the shell, the control mainboard is integrated with a wireless communication module, and the wireless communication module is electrically connected to the control mainboard. The number of the data line interfaces is equal to the number of the carbon dioxide concentration probes, and the length of each data line is not less than 1 meter.

[0006] In this monitoring device, multiple data line interfaces are set on the shell, each data line interface is connected to a carbon dioxide concentration probe through a data line, and the length of each data line is not less than 1 meter. In this way, when this device is applied to laboratory carbon dioxide concentration monitoring, carbon dioxide concentration probes can be laid in every corner of the laboratory, and each carbon dioxide concentration probe transmits the data obtained in the detection to the control main board through the data line. Since the control main board has an integrated wireless communication module, the control main board transmits the data obtained by each carbon dioxide concentration probe through the antenna. Since this monitoring device uses multiple carbon dioxide concentration probes, the monitoring results obtained by multiple probes are more reliable than those obtained by a single probe.

[0007] In this monitoring device, a longer data line can be used when necessary, so that the housing (and the parts inside the housing) can be located outside the laboratory. This can prevent the housing from being exposed to experimental animals in some special animal laboratories.

[0008] Similarly, this device is used to detect the carbon dioxide concentration of various experimental equipment (such as cell culture boxes). One monitoring device can monitor the carbon dioxide concentration of multiple experimental equipment.

[0009] Optionally, a control key panel is provided on the outer wall of the shell, and the control key panel is electrically connected to the control main board.

[0010] The function of the control keypad is to operate the control main board.

[0011] Optionally, a display screen is further included, which is arranged on the outer wall of the shell and is electrically connected to the control main board.

[0012] The function of the display screen is to display the information in the control main board.

[0013] Optionally, an auxiliary connecting plate is further included, wherein the auxiliary connecting plate is arranged on the outer wall of the shell, and the auxiliary connecting plate is provided with connecting screw holes, and the connecting screw holes do not contact the shell.

[0014] An auxiliary connecting plate is provided on the shell, and connecting screw holes are opened on the auxiliary connecting plate, so that the auxiliary connecting plate can be fixed at a place where it needs to be fixed by means of the connecting screw holes.

[0015] Specifically, the auxiliary connecting plate can be fixed to the outer wall of the housing by means of screws or bolts.

[0016] Optionally, a sink groove is provided on the auxiliary connecting plate, a magnetic piece is arranged in the sink groove, and the magnetic piece does not contact the shell.

[0017] The specific magnetic sheet can be set in the sink by gluing. Since the auxiliary connecting plate is provided with the magnetic sheet, the auxiliary connecting plate can be adsorbed on the steel plate (or other iron equipment) of the laboratory wall with the help of the magnetic attraction of the magnetic sheet. At the same time, since the magnetic sheet does not contact the shell, it is equivalent to the magnetic sheet being outside the shell, which can minimize the impact of the magnetic sheet on the electronic equipment and antenna in the shell.

[0018] Optionally, a hanging hole is provided on the auxiliary connecting plate, and the hanging hole does not contact the shell.

[0019] The purpose of providing the hanging hole is to facilitate hanging the entire shell at a desired place when the hanging conditions are met.

[0020] Optionally, there are no less than two auxiliary connecting plates, and the two auxiliary connecting plates are respectively located at both ends of the shell.

[0021] Specifically, each auxiliary connecting plate is provided with a hanging hole, a magnetic sheet and a connecting screw hole, so that when the shell is hung or fixed by magnetic sheet adsorption or screwed, the shell is guaranteed to have good stability.

[0022] Optionally, the shell is made of plastic.

[0023] The beneficial effect of the present invention is that multiple carbon dioxide concentration probes are adopted, and compared with detection by a single probe, the monitoring results obtained by the multiple probes are more reliable. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] As attached Figure 1 , Attachment Figure 2 And attached Figure 3 As shown, a wireless carbon dioxide concentration real-time monitoring device includes a shell 6 and a control motherboard 9. The control motherboard 9 is arranged in the shell 6 and also includes a plurality of carbon dioxide concentration probes 8 and an antenna 1. The outer wall of the shell 6 is provided with a plurality of data line interfaces 7, which are connected to the control motherboard 9. The carbon dioxide concentration probes 8 are connected to the data line interfaces 7 via data lines. The antenna 1 is provided on the outer wall of the shell 6. The control motherboard 9 is integrated with a wireless communication module, which is electrically connected to the control motherboard 9. The number of data line interfaces 7 is equal to the number of carbon dioxide concentration probes 8, and the length of each data line is not less than 1 meter.

[0031] In this monitoring device, a plurality of data line interfaces 7 are provided on the shell 6, and each data line interface 7 is connected to a carbon dioxide concentration probe 8 via a data line, and the length of each data line is not less than 1 meter. In this way, when this device is applied to laboratory carbon dioxide concentration monitoring, carbon dioxide concentration probes 8 can be laid in every corner of the laboratory, and each carbon dioxide concentration probe 8 transmits the data obtained in the detection to the control main board 9 via the data line. Since the control main board 9 has an integrated wireless communication module, the control main board 9 transmits the data obtained by each carbon dioxide concentration probe 8 through the antenna 1. Since this monitoring device uses multiple carbon dioxide concentration probes 8, the monitoring results obtained by multiple probes are more reliable than those obtained by a single probe.

[0032] In this monitoring device, when necessary, a longer data line can be used so that the housing 6 (and the parts in the housing 6) can be located outside the laboratory. In this way, for some special animal laboratories, the housing 6 can be prevented from being blocked by experimental animals.

[0033] Similarly, this device is used to detect the carbon dioxide concentration of various experimental equipment (such as cell culture boxes). One monitoring device can monitor the carbon dioxide concentration of multiple experimental equipment.

[0042] Specifically, the magnetic sheet 2 can be set in the sink 303 by gluing. Since the auxiliary connecting plate 3 is provided with the magnetic sheet 2, the auxiliary connecting plate 3 can be adsorbed on the steel plate (or other iron equipment) of the laboratory wall with the help of the magnetic attraction of the magnetic sheet 2. At the same time, since the magnetic sheet 2 is not in contact with the shell 6, it is equivalent to the magnetic sheet 2 being located outside the shell 6. This can minimize the impact of the magnetic sheet 2 on the electronic equipment and antenna 1 in the shell 6.

[0043] As attached Figure 1 , Attachment Figure 2 And attached Figure 3 As shown, a hanging hole 302 is provided on the auxiliary connecting plate 3 , and the hanging hole 302 does not contact the housing 6 .
