Abstract

A start-up device based on the electrode induction fingerprint identification belongs to the technical field of fingerprint identification devices, and comprises a plastic housing, a light source, a prism, an electrode material and a fingerprint identification induction module. The start-up device is characterized in that the fingerprint identification induction module comprises a capacitance change detection circuit; the light source, the prism and a lens are fixed in the plastic housing; more than one sensing electrode are fixed on the plastic housing; an outlet line of the electrode is electrically connected with the capacitance change detection circuit; and the capacitance change detection circuit is connected with a start-up trigger circuit. The start-up device has the advantages thatthe waterproof performance is good; the limitation of commercial power installation position is avoided; automatic start-up can be carried out so long as a user directly put a finger on the start-updevice, and is convenient; the power consumption is remarkably less than that of the infrared induction; and the service life of the product is prolonged.

Description

A kind of electrode induction fingerprint recognition starter gear
Technical field
The utility model belongs to the fingerprint identification device technical field, is specifically related to respond to automatically the device that fingerprint starts fingerprint recognition, discerns after the induction automatically when during use finger being put into fingerprint identification device, and does not need to start by other mechanical hook-up.
Background technology
In the prior art, the startup of fingerprint recognition system is following several: 1, by mechanical hook-ups such as buttons; The action of button must be arranged earlier when starting fingerprint identification device, not convenient, and increase mechanical hook-up such as button, potential faults increases.2 by the long term power source supply, allow fingerprint identification device be in starting state for a long time such as being connected to general distribution system, there is not the place of fixing power supply just can't realize to some such as door lock, and all be in starting state always, increase the loss of fingerprint identification device and the loss of the energy undoubtedly; Whether 3 be placed on certain position by the infrared induction finger starts fingerprint identification device, owing to use the less power supply supplies of capacity such as battery, power consumption is bigger, and total system is shorter service time, and is simultaneously invalid there being use under the environment of high light can receive the interference of high light; 4 by being fixed on the sheet metal above the fingerprint head, when being placed on the fingerprint head, finger connects circuit to start fingerprint identification device by finger contacting metal contact, sheet metal is exposed to the outside, being subjected to rain erosion for a long time can be invalid, also may cause recognition device to be in startup for a long time and cause power consumption excessive.
Summary of the invention
In order to overcome deficiency of the prior art, the purpose of this utility model is to provide a kind of electrode induction fingerprint recognition starter gear by auto-induction apparatus induction fingerprint, convenient and safe, low-power consumption, working stability.
For achieving the above object, the utility model adopts following technical scheme:
A kind of electrode induction fingerprint recognition starter gear comprises plastic casing, light source, prism and fingerprint recognition induction module, it is characterized in that described fingerprint recognition induction module comprises the capacitance variations testing circuit.Light source, prism and lens are fixed in the plastic casing, the described plastic casing inboard or the outside or one are injected with at least more than one sensing electrode, the output line of electrode is electrically connected with the capacitance variations testing circuit, and described capacitance variations testing circuit connects start triggering circuit.
Described sensing electrode embeds in the plastic casing.
Further again, described sensing electrode is a sheet metal.Can be selected from this areas such as chromium zirconium copper sheet, beryllium copper piece aluminum oxide copper sheet electrode material commonly used.
Fingerprint recognition starter gear compared to existing technology, its beneficial effect is:
Can start automatically when (1) user directly is placed on finger on the fingerprint identification device, very convenient.
(2) water resistance height is not limited to the fixed power source environment and uses.
(3) power consumption is starkly lower than infrared induction, can prolong the service time of whole recognition device, and the utility model device can avoid infrared induction to use the defective that lost efficacy under the high light environment.
Figure of description
Fig. 1 is the utility model one example structure synoptic diagram.
Embodiment
Come the utility model is further specified below in conjunction with specific embodiment, but the utility model is not limited to these embodiments.One skilled in the art would recognize that the utility model contained in claims scope all alternativess, improvement project and the equivalents that may comprise.
Embodiment 1
Electrode induction fingerprint recognition starter gear is the fingerprint head as shown in Figure 1, comprises prism 3, lens 5, plastic casing 1 and PCB wiring board 4.PCB wiring board 4 is integrated with the fingerprint recognition induction module, capacitance variations testing circuit, and trigger starting circuit.
Light source 6, prism 3 and lens 5 are fixed in the plastic casing, and light source 6 is positioned at prism and advances light face one side, and the optical axis of lens is vertical with the prism exiting surface.
The outside of plastic casing 1 is fixed with more than one sensing electrode 2, and the output line of electrode is electrically connected with the capacitance variations testing circuit, and the capacitance variations testing circuit connects start triggering circuit.
The present embodiment sensing electrode adopts sheet metal, also can use other electrode material, and it can be fixed in the middle of plastic casing outside or the embedding, or places between prism and the plastic casing.
During use, finger is placed on the fingerprint head, because finger can cause sheet metal (or other electrode materials) capacitance to change after placing and, and be communicated to capacitance variations testing circuit on the PCB wiring board by the information that the lead that connects changes electric capacity, the PCB wiring board sends instruction according to the capacitance variations value and starts fingerprint head harvester, thereby the automatic induction that has realized the fingerprint head starts.All the other contents are prior art, can be in detail referring to the design of optical fingerprint acquisition instrument technology.
