For the AC power source VSAC, a conversion unit AC-DC provided in the power conversion module 110 is connected to the AC power source VSAC through the second switch SW2, and converts the AC power source VSAC into a power supply voltage of the target board 200. Meanwhile, in order to meet the power supply requirements of different working modules, such as the control module 120 and the recording module, the power conversion module 111 further includes a conversion unit V1 and a conversion unit V2. For example, the supply voltage required by the control module 120 may be 12V, and the supply voltage required by the burn module may be 3.3V. When the recording device includes more required power supply voltages, the power conversion module 110 may include more conversion units.

When the number of output interfaces of the control host 121 does not meet the requirement of the burning modules, the expansion interface 122 (for example, a USB Hub circuit) may be used to expand the interfaces of the control host 121, so as to implement communication between the control host 121 and all the burning modules. For example, as shown in fig. 4, one expansion interface 122 corresponds to a plurality of burning modules (for example, the first burning module 131 and the second burning module 132 are both connected to one expansion interface 122). The expansion interface 122 can also be provided redundantly (for example, the output end of another expansion interface 122 is connected only to the third burning module 133).
With continued reference to fig. 3, on the basis of the foregoing embodiments, optionally, the portable card burning device further includes a storage module 160. The memory module 160 is electrically connected to the control module 120; specifically, the memory module 160 is electrically connected to the control host 121.

With continued reference to fig. 3, on the basis of the above embodiments, optionally, the portable burning device further includes a switch module 170. A first input end of the switch module 170 is electrically connected to a first output end of the power conversion module 110, a second input end of the switch module 170 is electrically connected to the control module 120, and an output end of the switch module 170 is used for being electrically connected to a power supply end of the target board card 200; the switch module 170 is used to enable an external power supply to supply power to the target board 200 through the power conversion module 110 when the switch module is turned on.
Specifically, the second input end of the switch module 170 is electrically connected to the control host 121, and the control host 121 controls the switch module 170 to be turned on or off, so as to power on or off the target board card 200. For example, after the burning of one CPU chip in the target board is completed, the switch module 170 may be controlled to be disconnected, and then the download line is reconnected; or when the target board 200 is inserted into the burning device, the switch module 170 is closed to power on the target board 200, and the target board 200 is taken down after the switch module 170 is disconnected, so that hot plugging is avoided in the whole process, and the operation safety is ensured. And the switch module 170 is arranged, so that the target board card 200 can be prevented from being burnt due to wrong connection of the front-end external power supply or the fault of the power conversion module 110. Illustratively, the switch module 170 may be an electronic switch SWD.
Fig. 4 is a schematic structural diagram of another portable board burning device provided in an embodiment of the present invention. Referring to fig. 4, on the basis of the foregoing embodiments, optionally, the power conversion module, the control module and the at least two burning modules are disposed on the circuit board 310. This portable integrated circuit board burns record device still includes: a case (not shown), a bracket 330 and a panel 320; the circuit board 310 is located below the panel 320 and fixedly connected with the panel 320; the panel 320 is secured within the housing by brackets 330.
Alternatively, the circuit board 310 may be secured under the panel 320 by copper posts.
With reference to fig. 4, optionally, the portable card burning device may further include a wire storage 340 for storing power wires, burning cables, small tools, and the like, so as to facilitate storage and arrangement of parts. The programming device is easy to age due to repeated plugging and unplugging of the programming cable after long-term use, which may cause the condition of program programming failure. For example, in a train system, since field personnel mostly upgrade the board in the skylight spot time at night, the time is short, and if the program burning fails, especially for a longer chip used for the program burning, the potential risk that the equipment state cannot be recovered in the skylight spot time exists, and the driving safety may be endangered. Therefore, in order to solve the problem of cable aging, the burning device also provides a replaceable burning flat cable.
With continued reference to fig. 4, preferably, the portable card burning device further includes a plug-in assistant 350 for assisting the plugging and unplugging of the card.
In fig. 4, a board socket is drawn exemplarily, and the scheme that burns record is carried out to the CPU chip in a target board, but not as right the utility model discloses a limit, when needs burn record to a plurality of boards, can expand a plurality of board sockets, burn record simultaneously to a plurality of boards. A switching circuit can also be designed to realize simultaneous burning of all CPU chips in the board card.
It should be noted that the foregoing is only a preferred embodiment of the present invention and the technical principles applied. It will be understood by those skilled in the art that the present invention is not limited to the particular embodiments described herein, but is capable of various obvious changes, rearrangements and substitutions as will now become apparent to those skilled in the art without departing from the scope of the invention. Therefore, although the present invention has been described in greater detail with reference to the above embodiments, the present invention is not limited to the above embodiments, and may include other equivalent embodiments without departing from the scope of the present invention.
