Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention aims to provide a waterproof and dustproof address setting device and method for an entrance guard card reader.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
Example 1
When the server communicates with the devices (card readers) below the bus of the server, the address of the card reader below the server needs to be acquired, so that each card reader needs to be provided with an address which is set by each card reader independently. For example, when a server is connected with 5 card readers, addresses of the 5 card readers are all different, and if addresses of two card readers are the same (for example, both addresses are 3 addresses), when the server communicates with the card reader with the 3 address, the two card readers with the 3 addresses send instruction information to the server at the same time, so that instructions sent by the two card readers are mixed together, the server cannot identify the card readers, and a fault occurs.
It should be noted that, when the address setting is performed once when the card reader is installed/initialized, the address of the card reader is fixedly stored in the memory of the card reader. Therefore, address setting is not needed when the follow-up server communicates with the card reader.
Based on the above, the present embodiment provides an address setting device of an access control card reader, please refer to fig. 1, where the device includes a single chip 1;
the single chip microcomputer 1 comprises a setting I/O port 2 for entering an address setting state, and the single chip microcomputer 1 is connected with an anti-dismantling switch 3 and a plurality of light emitting diodes 4;
the setting I/O port 2 can be the setting I/O port 2 defined by the original I/O port of the single chip microcomputer 1, or the setting I/O port 2 can be added to the single chip microcomputer 1 for setting.
The I/O port 2 is set to be grounded, the entrance guard card reader enters an address setting state, the anti-dismounting switch 3 is used for setting an address, and the light-emitting diodes 4 are used for displaying the currently set address;
the I/O port 2 is set to be disconnected, the entrance guard card reader is in a non-address setting state, and the anti-disassembly switch 3 is used for anti-disassembly alarming.
It should be noted that the premise that the tamper switch 3 is used for adjusting the address setting is that the I/O port 2 is short-circuited to the ground, and if the I/O port is not short-circuited, the tamper switch 3 has a tamper alarm function. The anti-disassembly alarm principle is that the anti-disassembly switch 3 is provided with a base and a switch button, the button is in a conducting state when being pressed down, and the button is in a disconnecting state when being loosened. The card reader is arranged on a wall, after the card reader is arranged on the wall, a switch button of the card reader is abutted against the wall and is in a conducting state, when the equipment is detached from the wall, the button is released, the connection is in a disconnecting state, and the card reader gives an alarm.
In this embodiment, the number of the corresponding light emitting diodes 4 may be set according to the number of the addresses of the card reader, where the relationship between the number of the light emitting diodes 4 and the number of the addresses of the card reader that needs to be set is: number of addresses 2Number of light emitting diodes。
The form of the display address of the plurality of light emitting diodes 4 may be selected as an address of a light display setting in a binary form. Please refer to fig. 2.
For example, when the number of the addresses of the card readers required to be set is 4, the number of the light emitting diodes 4 required is 2, and the addresses of the 4 card readers are respectively: 0, 1, 2 and 3. The plurality of light emitting diodes 4 display the set address in a binary manner, and when the last light emitting diode 4 of the 2 light emitting diodes 4 is on and the rest light emitting diodes 4 are off, the address displayed by the light emitting diode 4 is 1, that is: 201. When the penultimate led 4 of the 2 leds 4 is on and the rest of the leds 4 are off, the led 4 displays an address of 2, that is: 212. When 2 leds 4 are fully on, the address displayed by the led 4 is 3, that is: 20+213. The address value represented by each light-emitting diode is marked for the corresponding light-emitting diode, the address of the card reader is equal to the marked value of the lighted light-emitting diodes, and the identification is very simple.
The card reader address setting device provided by the embodiment is simple in structure and low in cost compared with the existing address setting device for installing the waterproof dial switch on the card reader, and only one I/O port 2 and the plurality of light emitting diodes 4 are arranged on the basis of the original card reader. Because the added light-emitting diodes 4 are all arranged in the card reader, compared with the arrangement mode that a dial switch is additionally arranged on the glue filling surface outside the plastic shell of the card reader in the prior art, the address setting device of the card reader in the embodiment has the waterproof and dustproof performance.
Example 2
The embodiment provides an address setting method of an access control card reader, which comprises the following steps:
when the I/O port 2 is set to be grounded, the anti-disassembly switch 3 is pressed to enable the plurality of light emitting diodes 4 to emit light to display the set address of the entrance guard card reader.
Wherein, whether the set I/O port 2 is grounded is judged by the singlechip 1.
In the setting address of the entrance guard card reader of this embodiment: minimum address is 0 and maximum address is 2Number of light emitting diodes-1。
When the number of the light emitting diodes 4 is 4, according to the formula: maximum address of 2Number of light emitting diodes 41, when the maximum address is 15, i.e. 4 leds 4 are fully lit, there are: 20+21+22+23＝15。
Optionally, as shown in fig. 3, when the I/O port 2 is set to be grounded, the setting address of the door access card reader is displayed by pressing the tamper switch 3 to allow the plurality of light emitting diodes 4 to emit light includes:
s11, grounding the set I/O port 2, triggering the anti-disassembly switch 3 to enable the current set address displayed by the plurality of light emitting diodes 4 to be 0;
it should be noted that, only during initialization, the I/O port 2 is set to be grounded, the current address displayed by the plurality of light emitting diodes 4 is 0, after address setting is performed, whether the set address is correct is checked, the I/O port 2 is set to be grounded, and the address displayed by the plurality of light emitting diodes 4 is the address of the card reader set last time.
The operation program needs to be triggered, the short circuit is triggered, and when the short circuit occurs, the operation program displays the current address and receives the key signal of the anti-dismounting switch 3.
When the current setting address is 0, the plurality of light emitting diodes 4 are in a complete off state, as shown in fig. 2 where the first row of light emitting diodes 4 is located.
S12, pressing the anti-dismantling switch 3 according to the address of the entrance guard card reader which needs to be set, and enabling a plurality of light emitting diodes 4 to emit light according to the pressing times of the anti-dismantling switch 3 so as to display the set address;
in this embodiment, the relationship between the number of times of pressing the tamper switch 3 and the address displayed by the light emitting diode 4 may be set such that, when the tamper switch 3 is pressed once, one is added to a plurality of addresses displayed by the light emitting diode 4, the tamper switch 3 is stopped being pressed until the plurality of light emitting diodes 4 display the address to be set, and the connection between the setting I/O port 2 and the ground is disconnected.
When the addresses displayed by the plurality of light-emitting diodes 4 are the maximum addresses, the anti-dismounting switch 3 is pressed once again, and the addresses displayed by the plurality of light-emitting diodes 4 are the minimum addresses.
Considering that in actual operation, the anti-tamper switch 3 is pressed once more due to an operation error, the anti-tamper switch 3 can be pressed towards the display address with the maximum display address, when the display address with the maximum display address is displayed, the anti-tamper switch 3 is pressed once more, the display address returns to the minimum address 0, and then the anti-tamper switch 3 is pressed according to the address required to be set.
And S13, disconnecting the set I/O port 2 from the ground, and storing the currently set address by the singlechip 1.
The short circuit to non-short circuit is also one-time trigger, so when the short circuit is disconnected, the key is not responded any more, and the singlechip 1 stores the currently set address.
The conventional method for setting the address of the card reader needs to install a dial switch, and because the dial switch is easy to be dialed by mistake, one more dial or one less dial needs to be calculated, misoperation is easy to cause, and under the condition of misoperation, whether the data is correct or not cannot be ensured, so that the data is unsafe. According to the method for setting the address of the card reader, the function can be achieved only by pressing the anti-dismounting switch 3 after the I/O port 2 needs to be set to be in short circuit with the ground, so that misoperation is not easy to occur, and data safety is guaranteed.
The embodiments in the present description are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments are referred to each other.
The principles and embodiments of the present invention have been described herein using specific examples, which are provided only to help understand the method and the core concept of the present invention; meanwhile, for a person skilled in the art, according to the idea of the present invention, the specific embodiments and the application range may be changed. In view of the above, the present disclosure should not be construed as limiting the invention.
