There is external equipment connection, can be used for confirmation data transfer direction, can be used for the plug of the external equipment of confirmation insertion
It is that positive insertion or anti-plug enter.
Optionally, controller 12 be also used to when identify external equipment 20 type after, for external equipment 20 provide with outside
The supply voltage of the type matching of portion's equipment 20.
Optionally, controller 12 includes micro-control unit (Microcontroller Unit, MCU).
Optionally, controller 12 passes through detection port 121 and the second detection 122 output pulse signal of port or low level letter
Number.
In the embodiment of the present application, controller 12 by detection port 121 and second detection 122 output pulse signal of port or
Low level signal can identify it is outer whether interface 11 has by the level of detection detection port 121 and the second detection port 122
The insertion of portion's equipment.For example, controller 12 exports the voltage of 0.2V by detection port 121 and the second detection port 122, work as detection
When voltage to detection port 121 and the second detection port 122 becomes 0V from 0.2V, that is, it can determine that interface 11 has external equipment to insert
Enter.
Optionally, the voltage of low level signal is located at predetermined voltage range.
In the embodiment of the present application, predetermined voltage range can be set in advance, for example predetermined voltage range can be set
Between 0.1~0.9V.The voltage range of low level signal is limited between 0.1~0.9V, since controller 12 passes through inspection
Port 121 and the second detection 122 output pulse signal of port or low level signal are surveyed, and detects port 121 and interface 11
The connection of first metal shell 111.Then the voltage of the first metal shell 111 is between 0.1~0.9V.If the electricity of low level signal
Pressure setting is too high (for example, being higher than 1V), be easy to cause the first metal shell 111 and the conducting liquid contacted that electrochemistry occurs
Corrosion.If the voltage setting of low level signal is too low (for example, be lower than 0.1V), the level of the first metal shell 111 be easy by
To interference, it will lead to controller 12 and the case where error detection occur.The voltage of low level signal can be consolidating between 0.1~0.9V
Definite value.Low level signal is that fixed voltage can detect whether external equipment insertion in order to controller 12.
Wherein, conducting liquid can be the liquid comprising electrolyte, for example, mineral water, coffee, fruit drink, tea-drinking
Material, soda etc..
Wherein, electrochemical corrosion is exactly that metal and electrolyte form two electrodes, forms corrosion galvanic cell, because metal
Electrode potential is always lower than the electrode potential of electrolyte, so metal is cathode, redox reaction, gold occur for metal and electrolyte
Category loses electronics and becomes metal oxide, causes to corrode to metal.Wherein, metal, electrolyte and current loop are electrochemistry corruption
The necessary condition of erosion.
Optionally, the voltage effective value of pulse signal is less than predetermined voltage threshold.
In the embodiment of the present application, voltage effective value refers to the average voltage in a pulse period.Predeterminated voltage threshold
Value can be set in advance.For example, predetermined voltage threshold can be set to 1V, at this point, the voltage effective value of pulse signal is small
In 1V.
Wherein, when the voltage effective value for detecting the pulse signal that port 121 exports is less than 1V, the first metal shell 111
Electrochemical corrosion is difficult to happen with conducting liquid.
Specifically, the duty ratio of pulse signal, less than 20%, the amplitude of pulse signal is less than 5 volts.
In the embodiment of the present application, when the duty ratio of pulse signal is less than 20%, the voltage effective value of pulse signal is lower.
When the amplitude of pulse signal is lower than 5V, when the duty ratio of pulse signal is less than 20%, the voltage value of pulse signal is lower than 1 volt.
When the voltage effective value of the first metal shell 111 of interface 11 is less than 1 volt, the first metal shell 111 of interface 11 with lead
Electro-hydraulic body is difficult to happen electrochemical corrosion.The duty ratio of pulse signal is set less than 20%, the amplitude of pulse signal is less than 5 volts
Spy can inhibit the first metal shell 111 of interface 11 that electrochemical corrosion occurs with conducting liquid.
Since the first metal shell 111 in interface 11 uses metal material, when the first metal shell 111 in interface 11
When being contacted with conducting liquid, since conducting liquid is equivalent to electrolyte, if the effective voltage on the first metal shell 111 reaches
When certain value, the electrochemical corrosion of the first metal shell 111 and conducting liquid can be accelerated.In the embodiment of the present application, controller 12
By detecting 121 output pulse signal of port or low level signal to the first metal shell 111, the voltage effective value of pulse signal
Lower than 1V, the voltage of low level signal is less than 1V, since the voltage effective value of the first metal shell 111 is lower, when the first metal
When shell 111 and conducting liquid contact, it can inhibit the first metal shell 111 that electrochemical corrosion occurs with conducting liquid.It is connecing
Mouthfuls 11 with external equipment when not connecting, even if the first metal shell 111 of interface 11 is contacted with conducting liquid, interface 11 is not yet
Electrochemical corrosion can occur.
In general, when the voltage effective value of the first metal shell 111 of interface 11 is higher than 1 volt, outside the first metal
Faster electrochemical corrosion can just occur for shell 111 and conducting liquid.When the voltage effective value of the first metal shell 111 is lower than 1 volt
When special, the first metal shell 111 is difficult to happen electrochemical corrosion with conducting liquid.
For example, if device processed 12 exports accounting for the pulse signal of the first metal shell 111 by detection port 121
For sky than being 1/10th, impulse amplitude is 3 volts, then the voltage effective value of the first metal shell 111 is 0.3 volt.0.3 volt
Less than 1 volt, even if the first metal shell 111 is contacted with conducting liquid, the first metal shell 111 is also difficult to send out with conducting liquid
Raw electrochemical corrosion.
