[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example:

[0022] Please see Figure 1-4 This utility model provides a technical solution: an embedded multi-channel data logger, including a logger 1, model TP9000 multi-channel data logger 1. The logger 1 can handle up to 64 channels, can be embedded, has a maximum sampling speed of 1 second, 70MB of built-in memory, and supports RS485 and RS232 communication. Optional Ethernet, WiFi, or GPRS communication interfaces are available. The logger 1 can be powered by either AC 90-250V or DC 24V. It features a 7-inch full-touch color display, USB interface for data export, a 278mm*278mm embedded mounting hole for easy rack mounting, fully isolated universal input, multiple signal acquisition capabilities, and an embedded handle for easy portability.

[0023] The recorder 1 has several plug-in slots 11 on its back. Each plug-in slot 11 is equipped with a plug-in module 7. There are eight plug-in slots 11. The models of the plug-in modules 7 are shown in Table 1.

[0024] Table 1. Model List of Plug-in Module 7

[0025]

[0026]

[0027] The recorder 1 is connected to the resistance temperature detector PT100 through the interface of the plug-in module 7 to measure the temperature at the industrial site; it is connected to the thermocouple 4 to measure the temperature at the site; and it is connected to the temperature and humidity sensor to measure the ambient temperature and humidity at the industrial site.

[0028] Limiting strip 9, several of which are provided and rotatably connected to the back of recorder 1, the surface of the limiting strip 9 is provided with a bayonet 14 to facilitate the connection between the limiting strip 9 and the stud 13;

[0029] The stud 13 is screwed to the plug-in module 7. The limiting strip 9 rotates so that the bayonet 14 fits onto the stud 13, thereby preventing the plug-in module 7 from detaching from the recorder 1. The surface of the plug-in module 7 is provided with a threaded groove 12. The stud 13 is screwed to the threaded groove 12. The part where the threaded groove 12 connects to the bayonet 14 is not threaded. The limiting strip 9 blocks the plug-in module 7, thereby preventing the plug-in module 7 from falling off.

[0030] In this embodiment, as Figure 1 As shown, the recorder 1 has a touch screen 3 and a button group 2 on its surface. Both the touch screen 3 and the button group 2 can be operated. Data can be viewed through the touch screen 3, including real-time numerical display, real-time curve display, historical curve display, and bar graph display.

[0031] In this embodiment, as Figure 2 As shown, the upper surface of the recorder 1 is provided with a U-shaped groove 5, and a handle 6 is rotatably connected inside the U-shaped groove 5. The U-shaped groove 5 keeps the handle 6 from protruding, so as not to affect the installation of the recorder 1 in the cabinet. Rotating the handle 6 vertically makes the recorder 1 easy to carry.

[0032] In this embodiment, as Figure 2 As shown, the recorder 1 has mounting holes 4 on both the left and right sides of its upper surface to enable positioning and installation of the recorder 1, prevent the recorder 1 from sliding in the cabinet, and improve the stability of the installation.

[0033] In this embodiment, as Figure 3 and Figure 4 As shown, a plug 10 is fixedly connected to the surface of the limiting strip 9. The plug 10 is plugged into the recorder 1. The plug 10 is inserted into the hole reserved in the recorder 1 and can rotate, thereby ensuring that the limiting strip 9 can rotate.

[0034] In this embodiment, as Figure 3 and Figure 4 As shown, the inner wall of the bayonet 14 is provided with two rubber balls 15. The rubber balls 15 are elastic and will not affect the connection between the bayonet 14 and the stud 13. The rubber balls 15 are used to hold the stud 13 in place to prevent the limit strip 9 from rotating freely.

[0035] In this embodiment, as Figure 4 As shown, a baffle 8 is fixedly connected to the end of the stud 13, which can lock the limiting strip 9 and improve the stability of the connection between the limiting strip 9 and the stud 13.

[0036] Specifically, during use, rotate the limiting strip 9 to make it vertical, ensuring that the limiting strip 9 does not block the insertion slot 11. After inserting the plug-in module 7 into the insertion slot 11, rotate the limiting strip 9 ninety degrees. The rubber ball 15 on the limiting strip 9 is stuck and squeezed by the stud 13. When the rubber ball 15 passes the stud 13, the limiting strip 9 is connected to the stud 13. The rubber ball 15 can prevent the limiting strip 9 from rotating freely, preventing the limiting strip 9 from separating from the stud 13, and ensuring a stable connection between the plug-in module 7 and the recorder 1.

[0037] At this time, the limit bar 9 blocks the plug-in module 7, preventing the plug-in module 7 from being removed from the plug slot 11. Compared with the traditional screw-on method of fixing the plug-in module 7, rotating the limit bar 9 is quick and easy to operate in narrow spaces such as cabinets.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
