Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with embodiment, further set forth the utility model.
As shown in Figure 1, the embedded passenger flow terminal of a kind of wireless wide area network comprises CPU, video input apparatus, wireless wide area network interface module, and power module.CPU adopts Leonardo da Vinci's chip TMS320DM6441 of TI company in the present embodiment, and it is the core of whole terminal, and it is responsible for the scheduling of video data processing, transmission and system coordination and task, the control of each interface etc.
It is the DDR2 internal memory of 128MB that CPU adopts 32bits data bit, capacity, model is HY5PS5162FFR-Y5/S5, the nonvolatile memory of CPU then adopts NOR FLASH, to improve the transfer efficiency of data, NOR FLASH is the 16bits data bit, and capacity is 8MB, and model is S29GL064N11TFIV20/TSOP56, the I/O level is 1.8V, and does not need level conversion between the CUP.
Be provided with reset circuit among the CPU, be input on the hand-reset signal of the chip that resets after hand-reset signal that it is produced by the chip that resets and watchdog reset signal are attempted by a circuit, both have one to produce the homing action chips such as CPU, NOR FLASH that will reset.
Feeding-dog signal is produced by the GPIO37 of CPU, whether feeds dog and is controlled by GPIO47.Implementation is the Enable Pin of a triple gate of GPIO47 control, and steering logic is as shown in the table:
| Sequence number | The GPIO47 state | Feed the dog situation |
| 1 | 1 | Triple gate output high-impedance state, no matter GPIO37 is any output, house dog can not worked, and promptly can not produce reset signal |
| 2 | 0 | The triple gate output signal is determined when GPIO37 in 1.6s exports 1 or 0 variation is arranged by GPIO37, house dog obtains normal feeding-dog signal, can not produce reset signal; If GPIO37 output does not have 1 or 0 variation in 1.6s, house dog can not get normal feeding-dog signal, will produce reset signal. |
Because CPU does not have before the programming BOOT, the GPIO47 output state is indefinite, can cause that house dog starts, and feeds the dog program simultaneously and also is not activated, and causes house dog to send reset signal, the CPU that resets, and with emulator programming boot the time, normally programming.For this reason, on the house dog outlet line, increase a wire jumper, when programming boot, pull up jumper wire device, make the watchdog reset signal not influence other chips, when plate carry program all programming intact after, again jumper wire device is plugged, realize watchdog function.
