Abstract

An entrance guard card reader comprises a reading head of a singlechip (1) connected with one end of each of a clock line (11) and a data line (12), the reading head comprises an electronic switch (2) connected with the other end of each of an inside red LED input line (21), an inside buzzer input line (22), the clock line (11) and the data line (12), and one of each of an external red LED input line (23) and an external buzzer input line (24), and the other end of each the external red LED input line (23) and the external buzzer input line (24) extends out of the reading head. Owing to the entrance guard card reader adopting the above structure, preset programs can be upgraded or updated at any time according to the requirements of customers, and a better waterproof grade of the card reader can be kept without damaging potted glue. Therefore, the card reader has a wider adaptability and lower cost.

Description

Gate inhibition's card reader

Technical field

The utility model relates to a kind of electronic access control system, relates in particular to a kind of gate inhibition's card reader.

Background technology

Existing electronic access control system all comprises card reader, is used to read on the badge canned data and sends to controller, and judged whether to open door by control device.At present, the read head on the card reader generally need reach the IP65 requirement, and whole read head needs encapsulating, be electrically connected port and can not expose and comprise upgrade interface, in case like this behind the encapsulating read head just can not change program; Get ready the goods for production and bring very big difficulty, ability encapsulating production after necessary wait customer demand is confirmed well, there is very big influence the delivery cycle; The client can not do a little customization functions after buying read head, can only change read head again; The maintenance in later stage is pretty troublesome, can only scrap after read head goes wrong.

For solving the renewal of pre-set programs in the reading card device, the method for available technology adopting is to reserve the interface that downloads in the read head in card reader, thereby often makes classification of waterproof can not reach requirement; In addition, also adopt the special wiring that downloads of reserving in the prior art, increased the cable radical like this, and the manufacturing cost of card reader is increased.

Summary of the invention

For this reason, the purpose of the utility model is to provide a kind of gate inhibition's card reader, even the read head of this card reader still can be upgraded or upgrades after encapsulating program.

For realizing above-mentioned purpose, the utility model provides a kind of gate inhibition's card reader, has read head, and said read head comprises single-chip microcomputer, is connected with each end of clock wiring and data wiring on the said single-chip microcomputer; It is characterized in that; Said read head also comprises electronic switch, is connected with each end of each other end, external red LED input wires and the outside hummer input wires of inner red LED input wires, inner hummer input wires, clock wiring and data wiring on the said electronic switch; Each other end of wherein said external red LED input wires, outside hummer input wires stretches out outside the read head.

Compared with prior art; By having said structure gate inhibition card reader; Can upgrade at any time or upgrade pre-set programs according to client's needs, need not destroy encapsulating and can keep the better classification of waterproof of card reader, therefore make card reader have adaptability widely; Thereby make things convenient for the manufacturer to get ready the goods, make things convenient for the customization sexual function to realize that the client also can download at the scene easily.Especially, realize the function that downloads with external red LED, the shared cable of outside hummer incoming line, reservation program is specially downloaded cable, can practice thrift the cable cost.

Preferably, also connect ground wire on the said electronic switch, the other end of said ground wire stretches out outside the said read head.

Preferably, said read head is through the clock wiring on the said single-chip microcomputer and data wiring and the realization program is downloaded.

Preferably, under the program normal operating conditions, said electronic switch makes said inner red LED input wires, inner hummer input wires be connected with said external red LED input wires, outside hummer input wires.

Preferably, under program updates or upgrade status, said electronic switch makes said clock input wires, data input wires be connected with said external red LED input wires, outside hummer input wires.

Preferably, said read head is connected with a cd-rom recorder.

Description of drawings

Fig. 1 is the read head structure principle chart of the utility model gate inhibition card reader, has reflected to realize the principle that external cabling downloads, and the connection status of wiring shown in the figure is the program normal operating conditions; And

Fig. 2 is a read head shown in Figure 1 and the synoptic diagram that is connected of cd-rom recorder.

Embodiment

The utility model gate inhibition card reader comprises read head R, and the structure principle chart of this read head R is as shown in Figure 1.Particularly, shown in left side square frame among Fig. 1, this read head R inner structure comprises single-chip microcomputer 1, is connected with each end of clock wiring 11 and data wiring 12 on this single-chip microcomputer.Read head R inside also comprises electronic switch 2; Be connected with each end and an end of ground wire 25 of each other end, external red LED input wires 23 and the outside hummer input wires 24 of inner red LED input wires 21, inner hummer input wires 22, clock wiring 11 and data wiring 12 on this electronic switch 2; Wherein each other end of external red LED input wires 23, outside hummer input wires 24, ground wire 25 stretches out outside the read head, shown in the square frame of Fig. 1 right side.

Wiring connection status shown in Figure 1 is the program normal operating conditions; Wherein, when preset, download through " clock, data "; And after pre-set programs; With the read head encapsulating, card reader is operate as normal under the pre-set programs state, and this moment, electronic switch 2 was communicated with inner red LED input wires 21 of the single-chip microcomputer of read head and inner hummer input wires 22 with external red LED input wires 23 and outside hummer input wires 24.

When needs change read head program; Electronic switch 2 will be connected with outside hummer input wires 24 with external red LED input wires 23 with each other end of clock wiring 11 and data wiring 12; These two wiring are switched on the function that downloads; Yet, perhaps these two wiring are switched to (as shown in Figure 2) on the external burning device 3 and " clock, data " wiring through single-chip microcomputer 1 realizes program updates or upgrading through the configuration card (not shown) of brush " downloading ".

This novel structure by the utility model; Need not destroy encapsulating and can keep the better classification of waterproof of card reader; And can be according to client's needs, therefore upgrading at any time or renewal pre-set programs make card reader have adaptability widely; Thereby make things convenient for the manufacturer to get ready the goods, make things convenient for the customization sexual function to realize that the client also can download at the scene easily.Preferably, realize the function that downloads with external red LED, the shared cable of outside hummer incoming line, reservation program is specially downloaded cable, can practice thrift the cable cost.
