Number, otherwise, send out speech verification failure signal；
Landing state detection device is arranged in liquid tank, and currently whether loading liquid oil condition is in for detecting liquid tank
Or unloading liquid oil condition, and when liquid tank is currently at loading liquid oil condition or unloading liquid oil condition, send out handling
Otherwise status signal sends out closed state signal；
Petroleum vapor recovery structure, including petroleum vapor recovery valve, ventilation recovery channel, ventilation reducer union, connector control switch and oil gas
Recycling can, wherein petroleum vapor recovery valve are arranged at the top of liquid tank, and petroleum vapor recovery tank is arranged in the left side of liquid tank, petroleum vapor recovery
Valve is connect by recovery channel of ventilating with petroleum vapor recovery tank, and petroleum vapor recovery valve is also connect with landing state detection device, is used for
When receiving landing state signal, the oil gas dissipated when automatically opening with by loading liquid oil or unloading liquid oil is by ventilating back
Closed tube road is collected into petroleum vapor recovery tank, and ventilation reducer union is connect with petroleum vapor recovery tank, in the on-state by oil gas
Recycling can exports, and connector control switch is connect with the facial recognition device and speech recognition apparatus respectively, for receiving
For image authentication by signal and when receiving speech verification and passing through signal, control ventilation reducer union enters opening state, otherwise,
Control ventilation reducer union enters closed state；
The poly-lens camera further includes flash lamp, brightness detection device and flash of light control device；
Wherein, the brightness detection device is used to detect and export the ambient brightness of the poly-lens camera, the flash of light
Control device is connect with the flash lamp and the brightness detection device respectively, for receiving the ambient brightness, and base
It is turned on and off the flash lamp in ambient brightness determination；
The flash of light control device is turned on and off the flash lamp based on ambient brightness determination：When described
When ambient brightness is more than or equal to predetermined luminance threshold value, the flash of light control device closes the flash lamp；
The flash of light control device is turned on and off the flash lamp based on ambient brightness determination：When described
When ambient brightness is less than predetermined luminance threshold value, the flash of light control device opens the flash lamp；
When the flash of light control device opens the flash lamp, the flash of light control device is true also according to the ambient brightness
The flash intensity that the fixed flash lamp is sent out；
The flash of light control device determines that the flash intensity that the flash lamp is sent out includes：The ambient brightness is smaller, institute
It is higher to state the flash intensity that flash lamp is sent out；
Petroleum vapor recovery valve is additionally operable to be automatically closed the oil gas to interrupt dissipation when receiving closed state signal by ventilating back
Closed tube road is collected into petroleum vapor recovery tank；
Wherein, the facial recognition device is realized by dsp chip, and the DSP processing chips have following features：（1）One
A multiplication and a sub-addition are completed in a instruction cycle；（2）Program and data space separates, while access instruction and data；
（3）There is quick RAM in piece, accessed simultaneously in two pieces by independent data/address bus；（4）It is followed with low overhead or without expense
Ring and the hardware supported redirected；（5）Quick interrupt processing and Hardware I/O are supported；（6）It is multiple with what is operated within the monocycle
Hardware address generator；（7）Multiple operations are executed parallel；（8）It supports pile line operation, make fetching, decoding and executes operation weight
It is folded to execute.
