[0031] Embodiment 1:

[0032] The utility model provides a data acquisition instrument based on cellular communication.

[0033] In one embodiment of the utility model, a data acquisition instrument based on cellular communication includes an acquisition instrument body 1, a plurality of interfaces 2 are arranged on one side of the acquisition instrument body 1, a protective cover 3 for shielding the interface 2 is arranged on the acquisition instrument body 1, and the side of the protective cover 3 opposite to the interface 2 is open, so that an external connector can extend into the protective cover 3 through the opening and be connected with the interface 2; a curtain 4 for covering the interface 2 is movably installed in the protective cover 3, one end of the curtain 4 extends out of the protective cover 3, and a cover plate 5 for closing the inner cavity of the protective cover 3 is movably installed at the opening of the protective cover 3, a sealing member 6 is arranged on the side wall of the cover plate 5, and the cover plate 5 and the curtain 4 are detachably connected.

[0034] It should be noted that in a data acquisition instrument based on cellular communication of the utility model, a control module, a storage module, a cellular communication module and a power module are arranged in the acquisition instrument body 1, wherein the control module is responsible for data processing and controlling the specific work flow of the entire acquisition instrument body 1, the control module can adopt a microprocessor or a microcontroller, such as ARM, AVR, etc., and the control module communicates with each module through an interface 2 such as a serial port, SPI, I2C, etc.; the storage module is used to store the collected data information, and can adopt a storage medium such as a Flash memory, an SD card, etc.; the cellular communication module is used to transmit the collected data information to a remote server through a cellular network, and the cellular communication module can adopt an NB-IoT module, a GPRS module, etc.; at the same time, the power module is used to provide a stable power supply for the acquisition instrument body 1, and the power module can adopt a battery-powered or external power supply.

[0035] Specifically, Figures 1 to 4 As shown, in a data collector based on cellular communication of the utility model, since a protective cover 3 and a plurality of interfaces 2 are provided on the collector body 1, and the protective cover 3 is open on one side relative to the plurality of interfaces 2, the external connector can be inserted into the protective cover 3 through the opening and connected with the interface 2, thereby realizing the electrical connection between the collector body 1 and the external device; at the same time, when the external connector and the interface 2 are in a connected state, the external connector and the interface 2 can be shielded by the protective cover 3, thereby preventing impurities such as dust and rain from falling into the connection between the external connector and the interface 2, thereby ensuring the connection reliability of the wiring, and the structural design is simple and reasonable. Furthermore, since a curtain 4 for covering the interface 2 is movably installed in the protective cover 3, when some of the interfaces 2 on the collector body 1 are not connected, the unconnected interfaces 2 can be shielded by the curtain 4, thereby effectively preventing impurities such as dust, particles or rainwater from falling into the unconnected interfaces 2, and preventing the unconnected interfaces 2 from having poor contact during the subsequent wiring process. This not only improves the reliability of the line connection and the stability of data transmission, but also reduces the safety hazard of wiring short circuits in the interfaces 2 due to rainwater, making it safe and reliable to use.

[0036] It is worth noting that the movable installation method of the curtain 4 and the protective cover 3 can be a sliding clamping connection, that is, the curtain 4 can slide along a certain direction of the protective cover 3 (specifically, the width direction of the protective cover 3) and can be clamped and limited by fasteners such as clamping blocks or bolts. When it is necessary to connect the external connector to the interface 2, the staff can push the curtain 4 in the direction away from the protective cover 3, so that the curtain 4 withdraws to the outside of the protective cover 3 and thereby removes the blocking of the interface 2, thereby facilitating the staff to connect the external connector to the interface 2, and the operation is simple; when the external connector is connected to the interface 2, the staff can push the curtain 4 to reset it and re-block the unconnected interface 2, thereby ensuring the protective effect of the interface 2 and reliable use.

[0037] It can be understood that since a cover plate 5 for closing the inner cavity of the protective cover 3 is movably installed at the opening of the protective cover 3, the cover plate 5 can be installed on the protective cover 3 by means of hinges, etc., so that the cover plate 5 can be rotated relative to the protective cover 3, meeting the needs of the staff to open the cover plate 5 and connect the external connector to the interface 2, and the structural design is simple and reasonable. Furthermore, when the collector body 1 is not in use, the staff can rotate the cover 5 to snap it into the opening of the protective cover 3, thereby closing the inner cavity of the protective cover 3 and isolating the interface 2 from the external environment, thereby effectively preventing dust and other impurities from accumulating and adhering to the interface 2 when the collector body 1 is not in use, thereby achieving dust-proof protection for the interface 2; at the same time, by providing a seal 6 on the side wall of the cover 5, the seal 6 can be a flexible sealing ring. When the cover 5 is snapped into the opening of the protective cover 3, the seal 6 is deformed and blocks the gap between the cover 5 and the protective cover 3, thereby effectively preventing liquids such as rainwater from entering the protective cover 3 and soaking the interface 2, which not only ensures the safety of the external connector when connected to the interface 2 and avoids safety hazards such as short circuits in the line, but also ensures the accuracy of data transmission, and achieves waterproof protection for the interface 2, which is reliable to use. In addition, since one end of the cover plate 5 is movably connected to the protective cover 3, and one end of the curtain 4 extends out of the protective cover 3, the cover plate 5 and the curtain 4 are detachably connected (such as threaded connection or pin clamping) to each other, thereby limiting the connection between the cover plate 5 and the curtain 4 to prevent the cover plate 5 and the curtain 4 from moving freely relative to the protective cover 3, thereby ensuring the installation stability of the cover plate 5 and the sealing effect of the protective cover 3.

[0038] In one embodiment, guide grooves 7 are respectively provided on the inner walls on both sides opposite to each other of the protective cover 3, and through grooves are provided on the side walls of the protective cover 3 at positions corresponding to the guide grooves 7. One end of the curtain 4 passes through the through groove and is in sliding contact with the guide groove 7, and the other end of the curtain 4 extends out of the protective cover 3 and is detachably connected to the cover plate 5.

[0039] Specifically, Figure 1 and Figure 4As shown, since one end of the curtain 4 passes through the through groove and is in sliding contact with the guide groove 7, the curtain 4 can slide along a preset path on the protective cover 3 through the sliding contact between the curtain 4 and the guide groove 7, thereby not only ensuring the sliding stability and smoothness of the curtain 4, but also ensuring that the curtain 4 can smoothly and effectively cover or expose the interface 2, and the structural design is simple and reasonable; at the same time, since the other end of the curtain 4 extends out of the protective cover 3, it is convenient for the staff to push and pull the curtain 4 to cover or expose the interface 2, which is conducive to operation. In addition, it should be noted that when the collector body 1 is not in use, the staff can snap the cover 5 onto the open part of the protective cover 3, and push the curtain 4 into the protective cover 3 to shield and protect the interface 2. At this time, the end of the curtain 4 extending outside the protective cover 3 can be detachably connected to the cover 5, and the detachable connection between the two can also be a snap-on connection, which not only limits the cover 5 and the curtain 4 to prevent the cover 5 and the curtain 4 from moving freely relative to the protective cover 3, but also allows the staff to easily and conveniently open the cover 5 and the curtain 4 to expose the interface 2 and connect it to the external connector, which is easy to use.

[0040] In one embodiment, if Figure 4 As shown, the end of the curtain 4 extending into the protective cover 3 is respectively detachably installed with the limit posts 8 near the two guide grooves 7. Specifically, the two limit posts 8 can effectively prevent the staff from completely pulling the entire curtain 4 out of the protective cover 3 when pushing and pulling the curtain 4 to expose the interface 2, thereby ensuring the stability of the installation of the curtain 4 in the protective cover 3; at the same time, the limit posts 8 can be studs in the prior art, which have the characteristics of simple structure and easy material acquisition. When the staff needs to remove or replace the curtain 4, the curtain 4 can be quickly and conveniently removed from the protective cover 3 by disassembling the limit posts 8, which is simple to operate and convenient for maintenance.

[0041] In another embodiment, a groove 9 is formed at one end of the curtain 4 extending out of the protective cover 3, a protrusion 10 for extending into the groove 9 is formed on the cover plate 5, a lock hole 11 is formed on the side wall of the protrusion 10, and a lock column 12 for plugging and cooperating with the lock hole 11 is movably installed on the upper limit position of the side wall of the curtain 4. Specifically, Figure 1 , Figure 3 and Figure 4As shown, when the cover plate 5 is buckled to the opening of the protective cover 3, the protrusion 10 on the cover plate 5 extends into the groove 9 on the curtain 4, thereby improving the tightness of the connection between the cover plate 5 and the curtain 4. Further, since a lock hole 11 is provided on the side wall of the protrusion 10, and a lock column 12 is installed on the side wall of the curtain 4 in a limited position and movable manner, the lock column 12 and the curtain 4 can be installed in a limited position and movable manner by sliding, that is, a slide groove is provided on the curtain 4, and a block extending into the slide groove is formed on the lock column 12, and the lock column 12 can slide relative to the curtain 4 through the sliding contact cooperation between the block and the slide groove, and the structural design is simple and reasonable; at the same time, when the cover plate 5 is buckled to the opening of the protective cover 3, the lock column 12 and the lock hole 11 are plugged and matched to firmly connect the cover plate 5 and the curtain 4, thereby effectively preventing the cover plate 5 and the curtain 4 from moving freely relative to the protective cover 3, and ensuring the shielding protection effect of the cover plate 5 and the curtain 4 on the interface 2. It is understandable that the staff can pull out the lock column 12 to disengage it from the lock hole 11, thereby disconnecting the cover 5 from the curtain 4, and then allowing the staff to rotate the cover 5 and expose the interface 2 to connect to an external connector, which is easy to use.

[0042] In yet another embodiment, specifically, Figure 1 , Figure 3 and Figure 4 As shown, a stepped hole is provided on the side wall of the curtain 4 at a position corresponding to the lock hole 11, and a lock column 12 is inserted into the stepped hole. One end of the lock column 12 extends out of the stepped hole and is formed with an annular flange 13. An elastic member is sleeved on the outer wall of the lock column 12, and the two ends of the elastic member are respectively connected to the annular flange 13 and the step surface of the stepped hole, so that the lock column 12 can be firmly installed in the stepped hole under the action of the elastic member and can be limitedly moved relative to the curtain 4. The structural design is simple and reasonable. Furthermore, when it is necessary to connect the external joint to the interface 2, the staff can pull the lock column 12 in a direction away from the protrusion 10 and disengage the lock column 12 from the lock hole 11. At this time, the elastic member is in a state of stretching and deformation, so that the connection between the cover plate 5 and the curtain 4 can be disconnected, so that the staff can rotate the cover plate 5 and move the curtain 4 to expose the interface 2, which is simple to operate. In addition, when it is necessary to connect the cover plate 5 with the curtain 4, the staff pulls out the lock column 12 so that the protrusion 10 can extend into the groove 9. After the protrusion 10 is completely accommodated in the groove 9, the lock column 12 is coaxially aligned with the lock hole 11. At this time, the staff releases the lock column 12, and the lock column 12 automatically extends into the lock hole 11 under the rebound action of the elastic member and always maintains a plug-in fit with the lock hole 11, thereby achieving a stable connection between the cover plate 5 and the curtain 4.

[0043] In one embodiment, specifically, Figure 1 and Figure 4As shown, a notch groove 14 is provided on one side of the cover plate 5 away from the protective cover 3, so that it is convenient for the staff to rotate the cover plate 5 to expose the interface 2, which is conducive to operation and convenient to use.

[0044] In one embodiment, a plurality of heat dissipation strips 15 are formed on the outer wall of the collector body 1. Specifically, Figure 1 and Figure 2 As shown, the contact area between the shell of the collector body 1 and the air can be increased by a plurality of heat dissipation strips 15, thereby improving the heat dissipation efficiency.

[0045] In one embodiment, a communication antenna 16 is provided on the collector body 1; a plurality of pads are arranged in a rectangular array on the bottom surface of the collector body 1. Figure 1 and Figure 2 As shown, the communication antenna 16 can improve the speed and stability of data transmission of the collector body 1; a number of pads can not only stably support the collector body 1, but also increase the gap between the bottom surface of the collector body 1 and the installation surface, thereby improving the heat dissipation efficiency of the collector body 1.

[0046] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
