Description

DETAILED DESCRIPTION OF THE INVENTION (a) Technical Field of the Invention The present invention relates to a method for remotely powering on a terminal during a system test of a terminal data information processing system.

(bl Background of technology) Recently, in horse racing, bicycle racing, boat racing, auto racing, etc.
It is operated by an online voting ticket information processing system that processes everything online, from selling voting tickets to counting, recording, displaying, and refunding.

In order to meet diverse needs, sales information can be sent to an online center using the input/output functions of hundreds to thousands of voting ticket sales terminals, and it is possible to grasp the sales status, count the number of votes generated, and vote. Calculation of refund amount after confirmation,
This information is connected to the center main computer of the online center by making full use of boss computers or front computers inside and outside the venue, such as the display function to display this information on large display devices and TVs, and the refund processing function on the refund voting ticket terminal device. , is operated as an online voting ticket information processing system.

Each terminal data information processing system inside and outside the venue in these online voting ticket information processing systems has several hundred to several thousand terminals installed within the same premises. For example, in a racetrack terminal data information processing system, the counters for purchasing voting tickets are dispersed in hundreds of locations, voting ticket sales terminals are placed at each counter in each scattered building, and the number of refund counters processing The 100 voting ticket refund terminals are also distributed in buildings scattered throughout the vast grounds. In addition, in each outside terminal data processing system, hundreds of voting ticket sales terminals, voting ticket refund terminals, etc. are distributed on every floor from the - floor to several floors, just like inside the venue, and from the sale of voting tickets to It is a data information processing system that processes a huge amount of data for processing everything from construction plans to refunds.

In order to operate thousands of these terminals and process randomly input data, the entire system must be operated on days other than race days so that the terminal data information processing system can always operate in the best condition. A lot of effort is spent on testing and maintenance.

(C1 Prior Art and Problems This kind of conventional terminal data information processing system will be explained.As the configuration of the terminal data information processing system,
Usually, there are 10 to 20 buildings on the same site that house several dozen to several hundred terminals, and the power supply to these terminals is provided by a power breaker for each building. It is supplied individually from the distribution board that you have. FIG. 1 shows a power supply and signal system diagram of a terminal data information processing system, where solid lines indicate AC power lines and dotted lines indicate control signal lines. 1 is a computer room for a terminal data information processing system, and a central control unit 2 and a distribution board 3 are installed in the computer room 1, and terminals 5a-5n in buildings 4a-4n are connected from the central control unit 2 to the computer room 1. A control signal line for controlling the terminals 6a to 6n is installed, and a power supply line for supplying power from the distribution board 3 to each building 4a to 4n is installed. Buildings 4a to 4n are scattered over a large site, and data information from terminals 5a to 5n, terminals 6a to 6n, etc. is collected and processed by the central control unit 2 in the computer room 1. Although the amount of data is enormous, it is also a large system deployed over a vast area.

In addition, FIG. 2 shows normal terminals 5a-5n and terminals 6a-5n.
-6n shows a circuit diagram for turning on power. Since the power-on circuits of each terminal use the same method, only one of them will be explained. The circuit to turn on the power is divided into a power-on circuit 7 and a power supply circuit 8. AC power is applied from the electromagnetic breaker 9 of the distribution board 3, the local on/off switch 10 is turned on, and the power-on circuit 7 is turned on. The rectified DC voltage drives the electromagnetic relay 11, closes the contact 12 of the electromagnetic relay 11, and drives the electromagnetic switch 13. Electromagnetic switch 1
3 is driven to close the switching contact 14 of the electromagnetic switch 13, AC power is applied to the stabilized DC power supply circuit 15, and a DC voltage is output from the output terminal 16 of the stabilized DC power supply circuit 15. The machine becomes operational.

When testing or maintaining the entire system, test (maintenance) personnel first go to buildings 4a-4n, which are scattered across a vast site, and test terminals 5a-5n and terminals 6.
To check the status of a-6n, turn on the local on/off switch 10 of each terminal individually and turn on the power.
While checking for any abnormalities such as whether there are disaster prevention hazards around each terminal, for example, whether there is a cover such as vinyl over the terminal, check all terminals i, terminals 5a-5, 5a-5, and the terminals 6, -6, become operational. Next, input operations are performed from each terminal to cause the central control unit 2 to generate and confirm a message, which is data information, and the like is carefully performed. In particular, from the standpoint of software development for central control unit 2, not only when developing software and connecting a large number of terminals on-site to perform software test 1, but also when making some modifications to the software once it has been completed. However, even if it is a small modification, high reliability must be guaranteed in these systems, which receive a lot of traffic from a large number of terminals during software testing.
) and test it.・Firmware (firmware)
mWare) For testing, it is necessary to turn on the power to terminals in some buildings one after another, and to turn on and off the power to terminals in some buildings, and each time it is strictly controlled. Test personnel ran around each building to test while opening and closing the building lock (to prevent theft) and turning on/off the local on/off switch 10 of the terminal, resulting in an extremely large amount of labor and time. becomes.

On the other hand, from a maintenance standpoint, it is truly inconvenient that the entire system cannot be tested and the normality of the system cannot be guaranteed unless personnel visit all the terminals each time. Therefore, it may be possible to simulate the operation as if many operators were operating the terminal at the same time, without the need for personnel to go to the terminal. This is relatively easy to achieve with today's microelectronic technology. However, there is a problem here as well. That is, even if such a simulator function were built-in, it would be pointless if personnel had to run around turning the power on and off of the terminal each time.

On the other hand, a method of remotely turning on the power of the terminal may also be considered. Normally, the central control unit, channel control unit, input/output devices, etc. in a computer room have a power control cable installed in a separate system in addition to the AC power cable, and the AC is first turned on to make each device receive power. After that, a power on (or off) signal is sent from the power control line to power on/off the device. It is, of course, possible in principle to apply something similar to this to each terminal, and in that case, the configuration may be as shown in FIG. 3. Figure 3 is a circuit diagram for turning on the power with remote/local switching contacts.
7 is a remote/local switching contact. That is, although it is configured to control the power on/off for each terminal by the central control unit 2 in the computer room 1 on the remote side, if the terminal is powered on unattended, If the terminal is covered with a cover such as vinyl, the terminal may overheat and cause a fire. Furthermore, installing a power control circuit inside the terminal and laying the power control cable in a separate system from the AC power cable for all terminals almost doubles the amount of power supply work. , economically disadvantageous.

In this way, in conventional terminal data information processing systems, when testing and maintaining a system that requires frequent power-on and shut-off of hundreds to thousands of terminals, the conventional method requires an enormous amount of effort. It took a lot of effort and time, and even if improvements were made, disaster prevention problems remained, and it had drawbacks such as requiring a huge amount of construction costs.

(dl OBJECT OF THE INVENTION The present invention aims to solve this conventional drawback.

tel Structure of the Invention The above object is to control a plurality of terminal power-on devices each including a power-on circuit for turning on/off power to a terminal, and a power supply circuit to which power is supplied when the power-on circuit turns on the power. , in a terminal data information processing system having a central processing unit that remotely controls the power supply circuits of each of the plurality of units, a timer that operates for a certain period of time by supplying power to each of the power supply circuits; The circuit has a lock switch that is operated during testing, and each of the above □
An electromagnetic relay driven by a remote control signal from the central processing unit is provided in the power-on circuit, and each of the lock switches is operated to supply power to each of the power supply circuits, thereby turning on the power of each of the power supply circuits. Each of the timers is activated, and within a certain period of time while each of the timers is activated, each of the electromagnetic relays is driven by a remote control signal from the central processing unit to perform a system test of the terminal data information processing system. This is achieved by the present invention configured as described above.

That is, at the beginning of a system test or maintenance test of the terminal data information processing system, the lock switch of all terminals is turned on, and then AC power is turned on to the terminals ta group all at once from the central distribution board. When power is applied to the power supply circuit of the terminal, the timer is activated, and within a set period of time during which the timer is activated, the central controller sends a remote control signal to keep the power on and all terminals are activated. By keeping the devices operational and turning off the lock switches on all devices at the end of the test, all devices can be easily powered on and off from the central control unit during the test period, without the lock switches being turned off. Or, even if a remote control signal is not sent due to an incorrect operation of the distribution board, the power that has been turned on will be myfI due to the operation of the timer, eliminating the risk of fire, etc., and making it effective as a remote power-on for each terminal. It provides a method.

ffl Embodiment of the Invention Figure 2 shows a terminal power-on circuit diagram according to the present invention, and the power-on circuit of each terminal has the same circuit configuration as this circuit diagram. 18 is a power supply circuit, 19 is a power supply circuit, 2
0 is the closing electromagnetic relay, 21 is the holding contact of the closing electromagnetic relay 20, 22 is the lock switch, and 23 is the closing electromagnetic relay 2.
0 is a closing contact, 24 is a timer, 25 is a remote control electromagnetic relay, 26 and 27 are normally closed timer contacts of timer 24, 28 is a remote control signal input terminal, 29 is a remote relay control circuit, and 30 is a remote control circuit. The closing and holding contacts of the control electromagnetic relay 25 are shown.

The circuit configuration of the present invention includes a power supply circuit 18 and a power supply circuit 1.
The power supply circuit 18 includes an electromagnetic switch 13.
A lock switch 22 is installed in series with the holding contact 21 of the closing electromagnetic relay 20 that drives the lock switch 22.
is on, when the AC power is turned on, the closing electromagnetic relay 20 is driven, and the closing contact 23 of the closing electromagnetic relay 20 is activated.
The electromagnetic switch 13 is driven, the switching contact 14 of the electromagnetic switch 13 is closed, power is immediately turned on to the stabilized DC power supply circuit 15, and the output terminal 16 of the stabilized side current power supply circuit 15 is turned on.
The device is configured to output a DC voltage from the terminal so that the terminal becomes operational. In this way, the power breakers for each building can be turned on one after another from the distribution board in the computer room, and the power to all terminals can be easily turned on. Furthermore, since the power is turned on for each building, there is no need to worry about overcurrent flowing into the system power supply due to rush current.

However, when this lock switch 22 is set to on, power is turned on to the terminal in an unattended state, which is dangerous in terms of disaster prevention. In other words, if you do not check the terminal at least once, there is a risk of a fire occurring.

Therefore, in order to check the status of all terminals, turn on the local on/off switch 10 of all the terminals individually and turn on the power. If the switch 10 is turned off and there are people coming and going, even if you check the status of the terminal once, for example, the operator may put a vinyl cover over the terminal or remove the fan. It is conceivable that placing something that is likely to cause damage to the air outlet may change the condition of the terminal, including the surroundings of the terminal. Therefore, if the lock switch 22 is left in the closed position during normal operation, it may become extremely dangerous if such disaster prevention management is not carried out thoroughly.

On the other hand, when conducting a test, you can choose a time in advance when there are no people coming or going, so even after checking the status of the terminal, you can
There is no change in status and remote injection is safe. However, the problem was that after the test was completed, I accidentally turned off the lock switch 22.
In order to prevent this, including the former, a timer 24 and a remote control electromagnetic relay 2 are installed on the output side of the stabilized DC power supply circuit 15 of the power supply circuit 19.
5 is provided.

The timer 24 is a normally closed switch,
The timer contacts 26 and 2 open after a certain period of time (for example, 5 minutes) after the stabilized DC power supply circuit 15 operates and the timer 24 is supplied with power and turned on.
It is a circuit with 7. The remote control electromagnetic relay 25 receives a remote control signal input from the central controller via the control unit of the terminal device and via the remote control signal input terminal 28.
Remote l#I! This is a relay that is operated by the signal output of the electric appliance control circuit 29, and is operated by a command in a telegram sent from the central control device to the terminal at the beginning of the test fence. The closing holding contact 30 of the remote control electromagnetic relay 25 is a contact that holds the closing electromagnetic relay 20 even if the timer contact 27 of the timer 24 is opened.

FIG. 5 shows a timing chart between each contact when the power is turned on. The fart is the voltage chart when AC power is applied by the power breaker on the distribution board, and R1 is the closing electromagnetic relay 20.
Closing chart diagram of closing contact 23, DC is output terminal 16
voltage chart diagram, tm is timer contact 26 of timer 24
is a switch opening chart of the timer contact 27, tl indicates a fixed time set by the timer 24, R2 is a closing/holding chart of the closing/holding contact 30 of the remote control electromagnetic relay 25, and t2 is the operation of the timer 24. It shows the time from when an operator in the recovery computer room manually inputs a power hold command, when a remote control signal is sent, until when the closing hold contact 30 of the remote control electromagnetic relay 25 closes.

The remote power-on sequence will be explained with reference to FIGS. 4 and 5. The electromagnetic breaker 9 of the distribution board is turned on and the AC chart is displayed.
The closing electromagnetic relay 20 is activated and the closing contact 23 is closed R1
The electromagnetic switch 13 is driven, the switching contact 14 is closed, and AC power is applied to the stabilized DC power supply circuit 15, resulting in a DC chart.

The timer 24 is activated by the power supply from the stabilized DC power supply circuit 15, and after the elapse of time t1, the timer contacts 26 and 27 are opened as shown in the tm chart, the closing electromagnetic relay 20 is restored, and the closing electromagnetic relay 20 is activated. The closing contact 23 is opened, the electromagnetic switch 13 is restored, the switching contact 14 is opened, and the supply of AC power to the stabilized DC power supply circuit 15 is stopped. When continuing the supply of AC power, the timer 24 operates and within 11 hours, within t2 time of the R2 chart,
When a hold command is input to the remote control signal input terminal 28, the remote control electromagnetic relay 25 is driven by the remote relay control circuit 29, and the closing/holding contact 30 of the remote control electromagnetic relay 25 controls the timer contact 26 and the timer contact 2.
7 is opened, the closing electromagnetic relay 20 is held and power is continuously supplied from the output terminal 16 to the terminal device. In case of interruption, if the remote control electromagnetic relay 25 is restored by the control of the remote relay control circuit 29, the closing holding contact 30 is opened and the closing electromagnetic relay 20 is restored, and the stabilized DC power supply circuit is restored by following the above-mentioned procedure. 15's power supply is stopped. In order to turn on all the terminals again, it is sufficient to turn off the electromagnetic breaker 9 of the variable power board and turn it on again.

As described above, if the hold command does not arrive at the remote control signal input terminal 28 within 11 hours, the timer contact 26
The timer contact 27 is opened, and the electromagnetic switch 13 is turned off. However, during normal operation, the remote control electromagnetic relay 25
No command is issued to run it.

With this configuration, at the beginning and end of the test period,
By turning on/off the lock switch 22, the power to all terminals can be easily turned on/off from the computer room.
