Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of rapid heat dissipation, the NFC building access controller of fire-proof and theft-proof, comprise shell, it is characterized in that: a side of described shell is provided with display screen, light-sensing region, described shell madial wall is provided with corresponding slideway A, slideway B, described slideway A, in slideway B, be provided with circuit board, on described circuit board, be welded with successively electric capacity A, electric capacity B, relay opens the door, alarm relay, main control chip, signal conversion chip, non-volatile memories sheet, power tube, described power tube tilts 40 °-60 °, the madial wall of described shell is provided with heat radiation baffle plate, described heat radiation baffle plate is near the bottom surface of power tube, in described shell, be also provided with fan, infrared transceiver, described enclosure is covered with antitheft shell, described antitheft shell and shell are fixed by socket head cap screw, between described shell and antitheft shell, be provided with flame retardant coating.
Also comprise insulator chain, described insulator chain is welded on circuit board by terminals.
Described power tube tilts 45 °.
The beneficial effects of the utility model are:
1 slideway that portion arranges fixing circuit board in the enclosure, assemble all very hommizations of maintenance, and structure is more firm, is convenient to promote the use of on a large scale.
2 in the enclosure portion heat radiation baffle plate is set, make power tube inclination certain angle abut against heat radiation baffle plate on, because the heat radiation of solid is better than gas, so that the heat radiation of power tube.
3 use non-volatile memories sheet, are that rush of current is larger because access controller is frequently on off state, and the stored record in chip is easy to be damaged, even if can normally use after maintenance, because user profile is lost, also can cause the inconvenience of use.
4 are covered with antitheft shell in the outside of shell, and are fixed on shell by socket head cap screw, are better than socket head cap screw location comparison hidden, and chien shih thief is beyond recognition in short-term, effectively prevents the generation of stolen phenomenon.
5 because access controller is generally arranged on open air, is easy to be struck by lightning, and on circuit board, welding insulation substring can effectively prevent thunderbolt.
6 are provided with flame retardant coating between shell and antitheft shell, can prevent that access controller is destroyed the in the situation that of breaking out of fire, thereby bring inconvenience to withdrawing of crowd.
