[0038] A Hall sensor 12 is provided in each of the matching areas 11, located at the center of the matching area 11, for detecting the existence and change of the magnetic field, and then generating an electrical signal after being triggered by the sand table component 13. Each of the Hall sensors 12 is provided with a specific and different magnetic field threshold range.

[0039] The signal light 15 is located on one side of the Hall sensor 12, and is used to display the operation result by turning the signal light on and off and the color of the light; the signal light 15 has multiple colors and lights up one by one, representing different operation results; wherein, when the sand table component 13 is not placed in the matching area 11, the signal light 15 is not lit; after the sand table component 13 is placed in the matching area 11, the signal light 15 lights up, and blue represents a correct placement operation, and red represents an incorrect placement operation.

[0040] Each of the coordination areas 11 represents an operation scene on the safety training table. In this embodiment, there are 9 coordination areas 11, namely, a first coordination area 11A, a second coordination area 11B, a third coordination area 11C, a fourth coordination area 11D, a fifth coordination area 11E, a sixth coordination area 11F, a seventh coordination area 11G, an eighth coordination area 11H and a ninth coordination area 11I.

[0043] Furthermore, the magnetic field size of each of the sand table component magnets 14 is different, and is matched one by one with the magnetic field threshold set by the Hall sensor 12. Each of the sand table components 13 is placed in a certain matching area 11, representing an operation step of a safety training. When the sand table component 13 matches with its corresponding matching area 11, that is, when the sand table component 13 is placed in a matching area 11 that matches its magnetic field size, the Hall sensor 12 in the matching area 11 outputs a high level, indicating that the sand table component 13 is placed correctly, that is, it represents that the operation step is correctly operated in the corresponding operation scene; when the sand table component 13 matches with a matching area 11 that does not correspond to it, that is, when the sand table component 13 is placed in a matching area 11 that does not match its magnetic field size, the Hall sensor 12 in the matching area 11 outputs a low level, indicating that the operation step is incorrectly operated in an operation scene that does not correspond to it.

[0044] In this embodiment, the sand table components 13 are provided with 9, namely, the first sand table component 13A', the second sand table component 13B', the third sand table component 13C', the fourth sand table component 13D', the fifth sand table component 13E', the sixth sand table component 13F', the seventh sand table component 13G', the eighth sand table component 13H', and the ninth sand table component 13I'; wherein, the first sand table component 13A' matches the first matching area 11A; the second sand table component 13B' matches the second matching area 11B; the third sand table component 13A' matches the first matching area 11A; the second sand table component 13B' matches the second matching area 11B; the third sand table component 13E ... third sand table component 13E' matches the first matching area 11A; the third sand table component 13E' matches the first matching area 11B; the third sand table component 13E' matches the first matching area 11A; the third sand table component 13 The tray component 13C' matches the third matching area 11C; the fourth sand tray component 13D' matches the fourth matching area 11D; the fifth sand tray component 13E' matches the fifth matching area 11E; the sixth sand tray component 13F' matches the sixth matching area 11F; the seventh sand tray component 13G' matches the seventh matching area 11G; the eighth sand tray component 13H' matches the eighth matching area 11H; the ninth sand tray component 13I' matches the ninth matching area 11I.

[0045] Specifically, the computer is a touch screen computer 2.

[0046] Among them, the touch screen computer 2 is a Windows operating system and is installed with a first system for running the safety training; further, the touch screen computer 2 is also wirelessly connected to the mobile terminal device 4; the functions of the first system include: receiving data transmitted by the circuit control system 3, and displaying the step operation status of the safety training on the display screen of the touch screen computer 2; receiving control instructions sent by the mobile terminal device 4 to perform safety training operations and demonstrate training-related materials.

[0047] Specifically, the touch screen computer 2 and the mobile terminal device 4 transmit signals via Bluetooth / WIFI / 2G / 3G / 4G / 5G communication.

[0048] In a specific embodiment of the present invention, the mobile terminal device 4 is a tablet computer; the tablet computer is an Android operating system, and is installed with a second system for controlling the touch screen computer 2, and the functions of the second system include: sending control instructions to the touch screen computer 2 to remotely turn on / off the touch screen computer 2; sending control instructions to the touch screen computer 2 to control the touch screen computer 2 to demonstrate practical training related materials; obtaining the results output by the touch screen computer 2.

[0049] Among them, Figure 4 As shown, the circuit control system 3 includes: a signal acquisition module 31, which is electrically connected to the Hall sensor 12 and is used to collect the high level / low level signal output by the Hall sensor 12 and carrying the position information of the matching area 11; a data analysis module 32, which is electrically connected to the signal acquisition module 31 and is used to analyze the high level / low level signal from the signal acquisition module 31 to obtain the analysis result of whether the sand table component 13 is placed in the matching area 11 matched therewith; a data receiving and sending module 34, which is connected to the signal acquisition module 31 and is used to transmit the high level / low level signal carrying the position information of the matching area 11 to the touch screen computer 2; a lighting control module 35, one end of which is electrically connected to the data analysis module 32 and the other end is electrically connected to the signal light 15 in the matching area 11, and is used to convert the analysis result of the data analysis module 32 into the control of the on and off and the color of the signal light 15 in the matching area 11 at the corresponding position.

[0050] Furthermore, the analysis method of the data analysis module 32 is as follows: when the data analysis module 32 receives a high-level signal carrying the position information of the matching area 11, it is analyzed that a sand table component 13 that matches it is placed in the matching area 11; when the data analysis module 32 receives a low-level signal carrying the position information of the matching area 11, it is analyzed that a sand table component 13 that does not match it is placed in the matching area 11.

[0051] Further, when the lighting control module 35 receives that a sand table component 13 that matches it is placed in the matching area 11, it controls the signal light 15 in the matching area 11 to light up blue; when the lighting control module 35 receives that a sand table component 13 that does not match it is placed in the matching area 11, it controls the signal light 15 in the matching area 11 to light up red.

[0052] The working principle of the present invention is as follows:

[0053] The 9 sandbox components 13 are respectively placed in the 9 matching areas 11, representing 9 simulated operation steps, and the 9 simulated operation steps have an operation sequence, which can be represented by steps 1-9 respectively. The operation results can be displayed through the touch screen computer 2, and when the operation is wrong, a voice prompt will be given. Specifically, the operator places the sand table component 13 in the groove of the matching matching area 11, and the sand table component magnet 14 at the bottom of the sand table component 13 contacts the Hall sensor 12 in the groove to generate a level signal. The signal acquisition module 31 in the circuit control system 3 collects the level signal of the Hall sensor 12, and analyzes through the data analysis module 32 whether a sand table component 13 matching it is placed in a certain matching area 11, and then controls the display of the signal light 15 through the lighting control module 35. If a sand table component 13 matching it is placed in a certain matching area 11, the signal light 15 in the matching area 11 will display blue, indicating that the placement operation is correct; if a sand table component 13 that does not match it is placed in a certain matching area 11, the signal light 15 in the matching area 11 will display red, indicating that the placement operation is wrong. At the same time, the high level / low level signal is sent to the touch screen computer 2 through the data receiving and sending module 34. The touch screen computer 2 displays the high level / low level signal data on the screen and obtains the operation result according to the signal data. When the touch screen computer 2 displays the low level signal data and further determines that the operation is wrong, a voice prompt will be given.

[0054] Take the first matching area 11A and the second matching area 11B as an example: if the first matching area 11A is placed with a matching first sand table component 13A', "11" is displayed on the touch screen computer 2; if the first matching area 11A is placed with a non-matching second sand table component 13B' / third sand table component 13C' / fourth sand table component 13D' / fifth sand table component 13E' / sixth sand table component 13F' / seventh sand table component 13G' / eighth sand table component 13H' / ninth sand table component 13I', "10" is displayed on the touch screen computer 2; If a matching second sand table component 13B' is placed on the second matching area 11B, "21" is displayed on the touch screen computer 2; if a non-matching first sand table component 13A' / third sand table component 13C' / fourth sand table component 13D' / fifth sand table component 13E' / sixth sand table component 13F' / seventh sand table component 13G' / eighth sand table component 13H' / ninth sand table component 13I' is placed on the second matching area 11B, "20" is displayed on the touch screen computer 2; the placement conditions of other matching areas and the level signal data displayed after placement are similar.

[0055] When all the operation steps are completed, that is, all the sandbox components 13 are placed in the matching area 11, 9 level data signals are displayed on the touch screen computer 2. Taking the result of a certain practical training operation as an example, the touch screen computer 2 displays "11", "31", "50", "41", "90", "20", "71", "60", "81", and the displayed signal data is compared with the correct operation sequence preset by the first system and the correctly placed signal data "11", "21", "31", "41", "51", "61", "71", "81", "91", which means that in this practical training operation, the first operation sequence is correct and the sand table component 13 is placed correctly, that is, the first sand table component 13A' that matches it is placed in the first matching area 11A; the second operation sequence is wrong, but the sand table component 13 is placed correctly, that is, the third sand table component 13C' that matches it is placed in the third matching area 11C; the third operation sequence is wrong, and the sand table component 13 is placed incorrectly, that is, the fifth sand table component 13E' that matches it is not placed in the fifth matching area 11E; the fourth operation The operation sequence is correct, and the sand table component 13 is placed correctly, that is, the fourth sand table component 13D' that matches it is placed in the fourth matching area 11D; the operation sequence in the fifth step is wrong, and the sand table component 13 is placed incorrectly, that is, the ninth sand table component 13I' that matches it is not placed in the ninth matching area 11I; the operation sequence in the sixth step is wrong, and the sand table component 13 is placed incorrectly, that is, the second sand table component 13B' that matches it is not placed in the second matching area 11B; the operation sequence in the seventh step is correct, and the sand table component 13 is placed correctly, that is, the seventh sand table component 13G' that matches it is placed in the seventh matching area 11G; the operation sequence in the eighth step is wrong, and the sand table component 13 is placed incorrectly, that is, the sixth sand table component 13F' that matches it is not placed in the sixth matching area 11F; the operation sequence in the ninth step is wrong, but the sand table component 13 is placed correctly, that is, the eighth sand table component 13H' that matches it is placed in the eighth matching area 11H.
