[0021] The present invention will be further illustrated below with reference to the accompanying drawings and specific embodiments. These embodiments are implemented based on the technical solutions of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0022] like Figures 1 to 5 As shown, an embodiment of the present invention provides a data acquisition box with KVM function, including a shell 13, one end of the shell 13 is a control area, and the other end is a storage area. A mainboard is provided inside the control area, and the storage area is divided into an upper layer and a lower layer by a partition 14. The upper layer is provided with an end cover 15 movably connected to the shell 13, and the lower layer is provided with a keyboard bracket 16 slidingly connected to the shell 13. The inner side of the end cover 15 is movably connected to the display screen 8, and the keyboard bracket 16 is fixedly connected to the industrial keyboard 9. The industrial keyboard 9 has a high protection level, has both buttons and a mouse, is convenient and safe to use, and is suitable for industrial scenarios.

[0023] Both ends of the outer side of the shell 13 of the storage area are provided with a first slide groove 20, and the two first slide grooves 20 are symmetrically arranged. The inner sides of the brackets 22 at both ends of the end cover 15 can be rotatably connected with the first sliders 21, and the two first sliders 21 are symmetrically arranged. The first sliders 21 are slidably connected to the corresponding first slide grooves 20. The shell 13 is also provided with movable grooves 23 that respectively cooperate with the brackets 22 at both ends of the end cover 15, and a baffle 24 that cooperates with the upper end surface of the end cover 15. When the end cover 15 is closed, the lower end surface of the baffle 24 contacts the upper end surface of the end cover 15, effectively preventing dust from falling into the data acquisition box from above.

[0024] Two symmetrical support plates 25 are fixedly connected to the upper inner portion of the end cap 15. A gap is left between the support plates 25 and the bracket 22, and the gap distance is greater than the thickness of the upper housing 13 of the storage area. The end cap 15 is also equipped with a position sensor 12, preferably a contact position sensor. When the end cap 15 is closed, the upper housing 13 of the storage area is located between the support plates 25 and the bracket 22. The position sensor 12 on the end cap 15 is pressed by the housing 13. When the end cap 15 is opened, a signal change is generated, thereby detecting the opening and closing of the end cap 15. Locking bolts 29 are also threadedly connected at each end of the end cap 15 to lock the end cap 15 when it is closed. Second slides 26 are defined on the inward side of each support plate 25. The two second slides 26 are symmetrically arranged. Second sliders 27 are rotatably connected to the two ends of the upper side of the display screen 8. The two second sliders 27 are symmetrically arranged and slidably connected to the corresponding second slides 26. A rubber corrugated pad 28 is fixedly connected to the partition 14 in the storage area. When the lower end of the display screen 8 is placed on different positions of the rubber corrugated pad 28, the display screen 8 is placed at different angles. The rubber corrugated pad 28 can not only prevent slipping well, but also serve as protection when the display screen 8 is stored.

[0025] In this embodiment, the first slider 21 and the second slider 27 are both horizontal cylindrical blocks that slide more smoothly in their corresponding slots. To open the end cover 15, loosen the locking bolt 29, pull the end cover 15 outward, and the first slider 21 moves in the first slot 20 until it moves from one end to the other. The end cover 15 is then rotated upward to open the end cover. When opened, the end cover 15 is perpendicular to the baffle 24. The presence of the second slot 26 and the second slider 27 allows for easy adjustment of the display screen 8, and the end cover 15 also serves as a support to hold the display screen 8 in place.

[0026] Both sides of the keyboard bracket 16 are slidably connected to the housing 13 in the storage area via three-section, ball-bearing slide rails 30. A handle 31 is also fixed to the keyboard bracket 16 to facilitate its removal. A guardrail 32 is integrally formed on one end of the outer side of the end cover 15. When the keyboard bracket 16 is stowed and the end cover 15 is in place, the inner surface of the guardrail 32 contacts the outer surface of one end of the keyboard bracket 16, preventing the keyboard bracket 16 from sliding outward after being stowed. In other words, the end cover 15 must be opened before the keyboard bracket 16 can be removed.

[0027] The housing 13 is also provided with a power interface 17 and several data interfaces 18 connected to the mainboard. The data interface 18 includes but is not limited to an Ethernet interface and a USB interface. The mainboard is provided with a power module 1, a KVM switching module 2, a data acquisition module 3, a data conversion module 4, a storage module 5, a communication module 6 and a main control module 7. The power module 1 is connected to the main control module 7 and the power interface 17 respectively to supply power to the device; the data interface 18 is connected to the data acquisition module 3, and the data acquisition module 3 collects data information from various on-site devices; the data acquisition module 3 is connected to the data conversion module 4, and the data conversion module 4 converts the data information collected by the data acquisition module 3 through a protocol and transmits the converted data information to the main control module 7; the industrial keyboard 9 and the display screen 8 are connected to the main control module 7 respectively, and the main control module 7 is connected to the KVM switching module 2, the data acquisition module 3, the data conversion module 4 and the data conversion module 4. The conversion module 4, storage module 5, communication module 6 and position sensor 12 are connected. The communication module 6 is a wireless communication module, and a 4G module can be optionally selected. The communication module 6 is wirelessly connected to the cloud platform; the KVM switching module 2 is connected to the field equipment through several KVM connecting lines. The KVM interface 19 on the KVM switching module 2, which is connected to the KVM connecting line, is arranged on the outside of the shell 13. The KVM interface 19 can be a network port or a serial port. It is designed according to actual needs. The KVM switching module 2 can receive the instructions from the main control module 7, determine which field device to execute, and transmit the instructions to the corresponding KVM connecting line connected to the field device. The KVM connecting line transmits the instructions to the field device.

[0028] A number of heat dissipation holes 33 are provided on the shell 13 of the control area, and a filter is provided at the heat dissipation holes 33 to prevent insects from entering the control area and to a certain extent prevent dust from entering the control area. A cooling fan 10 and a temperature sensor 11 are also fixed in the control area. The cooling fan 10 and the temperature sensor 11 are respectively connected to the main control module 7. When the temperature reaches the set value, the main control module 7 controls the cooling fan 10 to start and dissipate heat for the mainboard.

[0029] The data information collected by the data acquisition module 3 from each field device is converted by the data conversion module 4 and transmitted to the main control module 7. The main control module 7 distinguishes and classifies the converted data information for each field device and stores it in the storage module 5. At the same time, it packages the data packet and sends it to the cloud platform through the communication module 6. The position sensor 12 is used to detect the opening and closing status of the end cover 15. When the position sensor 12 detects that the end cover 15 is open, it transmits the opening signal to the main control module 7. The main control module 7 controls the display screen 8 to turn on and displays the distinguished and classified data information on the display screen 8. At this time, the industrial keyboard 9 can be controlled to input instructions. The main control module 7 reads the instructions and sends them to the KVM switching module 2. The KVM switching module 2 transmits the instructions to the field equipment through the corresponding KVM connection line to control the corresponding field equipment.
