EXAMPLE

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 is a perspective view of a ticket dispenser showing the arrangement of the device according to the invention.

According to the present invention, the main parts such as the ticket issuing unit 12, the banknote processing unit 13, the coin processing unit 14, and the upper communication unit 18, which are mounted inside the main body case 10 opened and closed by the door 11, are operated at the front operation unit. (16), applied to the ticket vending machine operated in conjunction with the rear operation unit 17 and the like, the micro switch 21, the ten key switch 22, the buzzer 23, and the like are further configured, and the main control unit 20 is provided. The idea is to change the algorithm of.

At this time, the micro switch 21 of the present invention is mounted to be in contact with the door 11 inside the main body case 10, and generates a predetermined signal when the door 11 is opened.

The micro switch 21 inverts the contact state of the inside depending on whether the protruding contact is pressed by the door 11. If the contact b is used, the contact is closed at the moment the door 11 is opened, and the contact is opened while the door 11 is closed so that no signal is generated.

In addition, the tenkey switch 22 of the present invention is mounted on the rear manipulation unit 17 and generates an input signal for a station attendant code, a work code, or the like.

The ten key switch 22 includes a number of input keys such as a number key of 0 to 9, an enter key, a delete key, and the like on a key matrix, and provides a specific binary signal for each key. It is associated with common circuit means for encoding. Since the rear operation unit 17 is installed rearward from the inside of the main body case 10, the door 11 may be opened to approach the tenkey switch 22. The signal input from the tenkey switch 22 includes an identification number (for example, '1234') unique to a station employee, a unique number for each job (for example, a coin supplement is '987'), and the like.

In addition, the buzzer 23 of the present invention is mounted inside the main body case 10, and generates an alarm sound when the door 11 is abnormally opened.

The buzzer 23 is used to have a maximum volume of the alarm sound to the station staff room, and the volume is appropriately adjusted by a variable resistor, etc. For the operation thereof, see FIG. The buzzer 23 is installed to be concealed inside the main body case 10 to prevent intentional damage before or during operation.

3 is a block diagram showing an input / output connection state of a main controller according to an embodiment of the present invention.

The main control unit 20 of the present invention stores the input signal of the tenkey switch 22 together with the time value while storing the time signal, and transmits the data to the DPU and the central monitoring panel through the upper communication unit 18. It is further equipped with a function.

In order to perform this algorithm, the main controller 20 is connected to the micro switch 21 for inputting a predetermined pulse signal as the door is opened, and inputs a predetermined digital signal as a station attendant manually inputs a code. It is connected to the Tenkey switch 22, and connected to the buzzer 23 which outputs a predetermined signal and alarms as the abnormal opening of the door is recognized by the input condition, and the input / output state of the signal is transmitted to the DPU and the central monitoring panel. It is connected to the upper communication unit 18 to transmit.

As described above, the main control unit 20 not only controls the operation of the ticket issuing unit 12, the banknote processing unit 13, the coin processing unit 14, etc., but also the state of the DPU and the central monitoring panel through the upper communication unit 18. In addition, as described later with reference to FIG. 4, the data transmitted from the micro switch 21, the ten key switch 22, and the like are also input, stored, compared, and transmitted.

4 is a flowchart showing an example of the operation according to the configuration of the present invention, in which reference numerals not shown refer to FIGS. 1 and 2.

The main control unit 20 operates the buzzer 23 when there is no input of the tenkey switch 22 within a predetermined time after the door 11 is opened or when the input of the tenkey switch 22 is different from the reference value. Is summarized.

In step ST10, the main controller 20 performs the operation flow according to the present invention as a subroutine program at regular intervals. However, a modified example of receiving the opening of the door 11 as an interrupt signal and performing it irregularly may be possible.

In step ST20, the main controller 20 detects the opening of the door 11 from the input of the microswitch 21, and if yes, goes to the next step, and if no, goes to step ST80. The input of the micro switch 21 should be determined as a signal that lasts for a predetermined time (for example, 2 seconds) to prevent an error due to a malfunction.

In step ST30, the main controller 20 determines whether the station employee code is input within a predetermined time (for example, 5 to 10 seconds) after the input of the micro switch 21, and if yes, goes to the next step and if no, goes to step ST70 and the buzzer 23 Rings.

In step ST40, the main control unit 20 determines whether the work code is input within a predetermined time (for example, 5 to 10 seconds) after inputting the station employee code, and if yes, goes to the next step and if no, goes to step ST70 and rings the buzzer 23.

In step ST50, the main control unit 20 stores the input code together with the date and time, and compares it with the reference value, if it is correct, goes to step ST80 and if it is wrong, goes to step ST70 to alert. The data on the operator and the contents of the work are coded in advance and stored in the memory of the main control unit 20. The data can be changed from time to time as necessary. The data such as date and time is used by a count / timer (not shown) of the main controller 20 which is a microcomputer circuit.

The alarm generated in the above-described step ST70 is detected when the door 11 is closed again in step ST20 while the subroutine program proceeds from step ST10, or when it is determined that the code input again in step ST50 is correct. Is off immediately. However, a predetermined switch (not shown) may be separately installed in the DPU and the central monitoring panel to be turned off by remote control by command transmission.

On the other hand, data on which station attendant opened the door 11 at what time and when the door 11 was closed is also stored in the memory of the main control unit 20, which is also transmitted to the DPU and the central monitor. The station attendant can output to the monitor or front desk for management.

Meanwhile, the above embodiment has been shown and described with respect to the ticket vending machine. However, in the case of the ticket issuing machine in which the station attendant individually issues tickets in the station attendant's room, the main part of the ticket vending machine is mostly overlapped with the ticket vending machine (for example, a coin processing part and a bill handling part). Since it is omitted, it is possible to apply the same configuration.

As described above, the ticket vending machine door opening and closing control apparatus of the present invention improves the input / output unit of the main control part in the ticket vending machine, which is applied as part of the subway station automation, thereby managing the history of opening of the door to prevent unauthorized use by station personnel. There is.

While the invention has been shown and described with reference to certain preferred embodiments, it will be appreciated that the invention can be variously modified and modified without departing from the spirit or scope of the invention as set forth in the following claims. One of ordinary skill in the art will readily know.
