Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides an automatic cash receiving machine, such as a dispensing machine installation room, where the machine and the installation room, etc. Regarding the program timer, which is controlled to operate according to a program, it is possible to set a program for a long period of time, for example, one year, and also to control each device according to time in response to events outside the preset program. This invention relates to a program timer that has a response function for multiple inputs.

[Prior art and its problems]

Conventional program timers operate or stop external devices at predetermined times according to generally preset programs, and have an additional function of responding to external inputs. Regarding,
It simply has the function of prohibiting the opening and closing of external equipment or allowing the current status to continue.

If there are a large number of inputs and you want to control a large number of output devices according to time, for example, an automatic cash register may be used to control a dispensing machine and related facilities; When controlling various devices individually over time, such as turning on and off (ON-OFF) power for machines, signboard lights, security equipment, etc., connect a clock device to a personal computer and use a dedicated control that matches the purpose of use. It is necessary to develop a program, and in a program timer system that uses a computer system and has a multi-input response function, not only is the equipment large-scale and extremely expensive, but also a lot of time is required to develop the program. It requires time and money.

Furthermore, if the automatic cash register is a device that only needs to be controlled based on time factors, such as the power supply of a dispensing machine, the purpose can be achieved by setting a program accordingly. For devices such as billboard lights that are installed, where it is desirable to change the lighting time depending on the season, it is not only extremely complicated to change the lighting time using a program, but also because the lighting time changes due to changes in the weather. This method has the disadvantage that it cannot cope with cases where control based on external factors unrelated to time is required, such as when a situation arises.

[Purpose of the invention]

The present invention has a response function to a large number of external inputs at a price comparable to that of a general program timer, and uses a special program storage method to simplify temporal operations on control equipment on a daily basis. It is an object of the present invention to provide a program timer which can be set manually using simple keys, and which can also easily set responses to a large number of inputs.

[Means for problem solving]

In order to achieve the above object, the present invention includes a timer operation storage device, a pattern registration section in which a plurality of types of i-ima operation patterns for one day are collected, and a timer operation storage device for each day of a long period of time such as 365 days. It consists of a date registration section that assigns which operation pattern to execute, and allows you to easily set up complex and long-term programs. The main feature is that the control device only responds to external input within a certain period of time based on the state in which the storage device is set in advance to enable or disable the external input. be.

〔Example〕

Hereinafter, the present invention will be described in detail based on embodiments shown in the drawings.

The illustrated embodiment is a case in which the program timer of the present invention is applied to a room in which an automatic cash receiving machine is installed in a financial institution, but the application is not limited to this. It is of course possible to use machines, unmanned stores, and other similar facilities.

FIG. 1 is a block diagram schematically showing a program timer of the present invention in one embodiment, in which reference numeral 1 is a key input device for programming timer operations and responses to sensor inputs, and 2 is a sensor input device. 3 is a memory device for timer operation, 4 is a memory device for input response sequence, 5 is a control device, 6 is a crystal calendar clock using a crystal oscillator, 7 is a display, 8 is a control output circuit, 9 is a control program for the control device 5, 10 is an automatic power supply switching circuit during a power outage, 1
1 is a backup DC'i! using batteries etc. Source, 1
2 is a power supply device.

The key input device 1 is equipped with 16 keys consisting of 10 types of numbers and 6 types of function keys, and by operating the keys, the time of the calendar clock 6 can be set and corrected, and the timer operation for the timer operation storage device 3 can be performed. , and a response sequence for each external input can be set in the input response sequence storage device 4.

The display device 7 is a display device using a light emitting diode or a liquid crystal, and normally displays the time that the calendar clock 6 is currently counting, which is September 9, 2017.

It is configured such that the week, day of the week, 9:01, the state of control output, and the state of sensor input as external input can be switched and displayed by key operation on the key input device 1.

The control device 5 controls each operation of a timer operation and an input response, and can be constructed at low cost by a microcomputer LSI of about 4 to 8 bits and its control program 9. In this control device 5, the current time taken out from the calendar clock 6 and the timer operation time stored in the timer operation storage device 3 are constantly compared by the comparison means, and the set time and the current time are used for timer operation. The control output circuit 8 is opened and closed by the opening/closing means according to the set operation at the time when the above coincides with the control output circuit 8. Furthermore, regarding the timer operation, in addition to controlling the opening and closing of the control output circuit 8, the A selection program for validating/invalidating external inputs from sensors, etc. is set in the timer operation storage device 3, and the external inputs are controlled by the control device 5 and the control output circuit 8 is opened and closed by the opening/closing means only within the valid time. However, responses to external inputs can be executed only within a certain period of time, and in short, whether or not to respond to each external input is managed by the program based on time.

Regarding the control of the response to the external input, if an input is given to the external input circuit 2 from an external factor or from a sensor within the time that is valid under the control of the timer operation, the information is transmitted to the control device 5. The sequence set in the input response sequence storage device 4 is input to the control device 5.
is taken out, and the control output circuit 8 is opened and closed according to its contents. During the operation of the input response sequence, the opening and closing of the control output circuit 8 is given priority to the input response sequence over the control output by the timer operation, and the response sequence is The timer operation will be restored at the same time as the case ends.

Further, the control device 5 is configured to determine the content to be displayed on the display 7 by operating a function key on the key input device 1.

When a microcomputer is used in the control device 5, the timer operation storage device 3 and the input response sequence storage device 4 can be constructed by connecting a RAM memory to the microcomputer of the control device 5.
Use a low power consumption type RAM memory,
In the event of a power outage, the automatic switching circuit 10 switches to the backup DC power supply 11 to supply power, thereby making it possible to retain the stored contents.

The calendar clock 6 can be obtained at low cost by using an electronic calendar crystal clock LSI circuit whose primary oscillation is the imaging of a crystal resonator. L.S.
A low power consumption type is used for I, and in the same way as in the RAM memory used for both storage devices 3 and 4, the backup DC power supply 1 is switched on by the automatic switching circuit 10 in the event of a power outage.
This allows the clock to continue counting by switching to 1 and supplying power.

Next, the operation of the timer operation memory device 3 will be explained with reference to FIG.

The timer operation storage device 3 consists of a pattern registration section and a date registration section, and the pattern registration section stores the required number of timer operation patterns for one day, as shown in ■ and ■. It is a collection of storage means, and the maximum number of patterns is determined by the capacity of the storage device.

Regarding operation patterns, one pattern is 24 times for one day.
At what point in time do output devices open and close (0
4. Instructs the time, type of output device, and control designation (0N-OFF) as to whether to turn it off (ON-OFF).
The required number of registrations is made every time control is required. Regarding the registration of opening/closing control, all that is needed is 3 bytes of memory for one opening/closing control, as shown in ■ in Figure 2. If the number of device controls per day is set to 40 at most, the memory capacity is 120 bytes. One day's worth of device opening/closing controls can be registered, and the number of permissible opening/closing controls for one day is determined by the capacity of the storage device. One time control information is ■
As shown in , the control type (ON or OFF), validity/invalidity for input response, control time, control output number, and input response channel number. By setting the minimum value of the control time to minutes, a maximum of 128 types of output devices can be controlled at any time with the minimum unit of 1 minute during 24 hours.

The type of control output is not all used to control the output device, but a part of it is used to enable/disable the input response, and the storage capacity of the pattern registration committee including this is 1 If the number of controls per day is 40 and the number of patterns is 10, [3 bytes x 40 x] O = 1
It is 200J, which is only 1200 bytes.

The date registration unit in the timer operation storage device 3 is a storage means that allocates which operation pattern is to be executed for each of the 365 days of one year, as shown in I in FIG. A capacity of 365 bytes is sufficient. By patterning the daily control and assigning the pattern type to each day of the year, it is possible to control a large number of devices on a minute-by-minute basis throughout the year with a total storage capacity of only 1565 bytes. It can be done.

When assigning actual movement patterns, 36
It is rare to control all five days using different operation patterns, and generally it is sufficient to be able to control each day of the week, and the number of operation patterns may be about 10.

It goes without saying that the desired number of operation patterns can be obtained by increasing the storage capacity.

In this way, the storage device is divided into a pattern registration section and a date registration section, and the patterns and dates of both sections are not only allocated, but also expedient methods such as allocation based on common features such as days of the week are used. This not only makes it possible to efficiently program and control a large number of devices on a minute-by-minute basis over a long period of time, such as a year, even with a small storage device, but also greatly simplifies the setting work for timers. It will become.

Regarding the settings for the timer in the timer operation storage device 3, first register the required number of 24-hour operation patterns using the key input device l, and then register the operation patterns for each of the 365 days of the year. However, it is inefficient to assign the desired movement pattern number to each day for all 365 days, so if we adopt a method of assigning the same pattern to the same day of the week, only 7 One year's worth of patterns can be assigned based on one setting operation. For exceptional days such as year-end and New Year holidays or national holidays, all that is needed is to reallocate the dates by date after assigning by day of the week.

The input response sequence storage device 4 may have almost the same configuration as the pattern registration section in the timer operation storage device 3 as shown in FIG. It is a storage means that collects a necessary number of such patterns, and normally it is sufficient to have the same number of patterns as the number of external input devices, and it instructs the operation time from the time of sensor input, the type of output device, and control designation. It is something.

The meaning of time in the program settings for the timer operation storage device 3 is the time itself with the start of the day being 0:00, but the meaning of time in the input response sequence settings is relative time, that is, the time when the sensor This is a relative time for an input operation, with time 0 o'clock being the time when the event is transmitted to the control device 5 via the external input circuit 2.

An example of when the input response function is activated will be explained with reference to FIG. 4. The figure is a time chart regarding the opening and closing of the electric lock attached to the entrance door of the cash machine installation room and the opening and closing of the notification device. , first timer operation storage device 3
The control output circuit 8 outputs the control output circuit 8 according to a program preset to
In addition to setting the electric lock in the unlocked state by the first control output at When a photoelectric sensor that reacts when a person passes is connected, the signal from the photoelectric sensor is input to the external input circuit 2 each time a person passes, but the input is invalid during the time when the electric lock is unlocked. Therefore, regardless of the signal input from the sensor, there is no response, and since the input is valid during the period when the electric lock is locked, the photoelectric sensor responds to the passing of a person during this valid period and the When a signal is input to the first input, a response sequence preset in the input response sequence storage device 4 is activated, and the notification device is activated for a certain period of time via the second control output in the control output circuit 8. It is possible to turn it ON.

FIG. 5 is a time chart of the blinking control of the signboard lights, which starts with a specific time period in the evening during the business hours of the store according to a program preset in the timer operation storage device 3. In addition to turning on the signboard light by the third control output in the control output circuit 8, the second input in the external input circuit 2 is enabled to set the store's business hours except for the specific time in the evening. If you connect an illuminance sensor to the second input that measures the outdoor brightness and issues a signal when the brightness falls below a certain level, the illuminance sensor will output a signal when the outdoor area becomes dark to a certain level. When a signal is applied to the second input in the external input circuit 2, and if that time is within the effective time period of the sensor input, a response sequence preset in the input response sequence storage device 4 is activated, and the control output is Through the third control output in circuit 8, the signboard light can be turned on for a certain period of time even though the timer operation is not used to turn on the signboard light, and the signboard light can be turned on for a certain period of time even when the timer operation is not performed. If the sensor input becomes invalid during the lighting time of the light, the control returns to the timer operation, but in the illustrated example, the light is turned on by the timer operation at the same time as the sensor input becomes invalid. That's what happens.

Although the operations according to the input response sequences illustrated in FIGS. 4 and 5 are given as simple examples, the program timer of the present invention can easily perform input response sequences that are significantly more complex than these. It can be done.

[Effects of the Invention] As explained above, according to the present invention, the timer operation storage device is connected to the pattern registration section in which one day's worth of timer operation patterns are collected, and which one for each day over a long period of time. By having a date registration section that assigns whether or not to execute a pattern, it is possible to easily set up complex and long-term programs using simple and inexpensive equipment. A storage device is provided to store a program for selecting either valid or invalid input from the external input device, and when the external input is valid, the control device controls the external input and outputs it as a control output with priority given to the output by the timer operation. As a result, it is possible to control the external device through timer operation and temporarily switch to operation based on the input response sequence based on the input from the external device, and therefore a large number of external output devices and input devices are involved. Automatic cash registers are suitable as program timers in rooms where payment machines are installed.
