Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a vending machine having a PH
The present invention relates to a PHS connection device for collecting sales data by connecting an S telephone, and particularly to a vending machine PHS connection device capable of performing communication in accordance with a communication method of a center device and collecting data with high reliability and efficiency.

[0002]

2. Description of the Related Art In order to increase the efficiency of delivery operations by grasping sales information and inventory information of vending machines at sales offices and delivery vehicles, and by notifying failure information and sold-out information from vending machines. In order to reduce loss of sales opportunities, various data collected from vending machines are collected by a center device and used for sales management. Conventionally, data has been collected via a wired line such as a public telephone line. However, data collection is not possible in places where there is no telephone line nearby and wired connection is not possible.Even if there is a telephone line, line connection work is required every time a vending machine is relocated. Cost.

[0005] Therefore, a wireless device has been installed in a vending machine, and data has been collected via a wireless line. In particular, recently, since PHS communication has become available, vending machines and center devices have been connected by a public line or a PBX PHS telephone to collect data. However, if the vending machine and the center device are all connected by PHS communication, the communication cost becomes high, so that low-cost communication is performed using the transceiver function of the PHS telephone.

[0004] A plurality of vending machines are grouped, one PHS parent device is provided, and a PHS telephone is connected to the vending machine to be a child device. The parent device is connected to the center device, the child device is connected to the parent device, data of the child device is collected in the parent device using the transceiver function, and the collected data is transmitted from the parent device to the center device. When the transceiver function of the PHS telephone is used, communication is possible in a narrow range, but communication with a remote child device may not be possible. If data is serially transferred via a child device near the parent device, data may not be delivered depending on the propagation state of radio waves. Therefore,
A bypass route for data transfer via a relay child device is provided. The child device serving as a router or a repeater selects an advantageous route having a strong electric field strength and transfers data.

[0005] A PHS of a conventional vending machine data collection device
In a telephone, digital data is converted into an analog signal in a voice band by a modem, and communication is performed using deemed voice communication. Only low-speed communication is possible with deemed voice communication. However, recently, PIAFS (PH
32 kbps digital communication is now possible using a method called S Internet Access Forum Standard (Piuff). The PIAFS method is called “32K high-speed data communication” or the like, and performs data transmission at 32 kbps.
However, the frame structure of PIAFS is called a piggybacking method, and in a fixed frame of 640 bits,
Since 24 bits of control information and 32 bits of error detection information are included, the user data is 584 bits, and the actual transmission speed of the user data is 29.2 kbps.

In a vending machine PHS connection device, a PIAF
By connecting a PHS phone that supports S communication,
It enables data communication at a throughput of 29.2 kbps. As a result, the amount of data per vending machine (approx.
4000 bytes) in a few seconds. FIG. 9 shows a basic connection configuration in this system.

A plurality of vending machines installed in one building are each provided with a vending machine PHS connection device. One of these vending machine PHS connection devices is a parent device,
The other vending machine PHS connection device is a child device. The parent device totals the sales data of the vending machines connected to the parent device, receives the sales data from each child device, and transmits control data to each child device. The parent device transmits the aggregated sales data to the center device via the base station and the public line, and receives control data from the center device. The PHS communication is performed between the parent device and the base station, and the transceiver communication is performed between the parent device and the child devices 1 and 2. Communication between the parent device and the child device 3 is performed by relaying the child device 2. Even if there is a radio wave barrier that prevents the child device 3 from directly communicating with the parent device, communication can be performed via the child device 2.

[0008]

A conventional vending machine PH
In the S connection device, sales data is collected and accumulated at regular intervals (for example, every hour) from child devices in a parent device in one group. However, when the size of the group increases and a maximum of 50 child devices are connected to one parent device, and the connection configuration between the child devices becomes complicated, a temporary communication failure occurs on the communication path along the way. The periodic data from the child device does not reach the parent device within the cycle, and the data of the next cycle arrives at the parent device first. For example, when a large truck is parked between child devices and shields radio waves, direct communication cannot be performed, and communication is performed using a bypass route. Since two PHS telephones cannot communicate with two at the same time, if the bypass communication path is long, the effective transfer speed will be extremely reduced, and the data may take one hour or more. May occur. One sales data is about 4KB, 50
Since each unit is 200 KB, the parent device cannot have many times as much memory as that of the parent device.
Only one data can be stored. If the old data arrives later and updates the data, the old data is eventually accumulated in the parent device, and the latest data may not be collected in some cases.

Further, in the conventional vending machine PHS connection device, for communication with a center device having only a wired line,
Alternatively, it has a communication unit with an external modem for a wired line so that it can be used even without a PHS base station. When an external modem is used, the external modem sometimes runs out of control for some reason and does not operate. In such a situation, there was no way to recover except by manually resetting the external modem.

In the conventional vending machine PHS connection device, control data received by the parent device from the center device is transferred to the child device each time the parent device communicates with the center device. The control data is data relating to conditions for transmitting information such as breakdown or sold out from the vending machine to the center device. Originally, since the center device controls the operation of the vending machine, the center device and the vending machine are used. Are sent when one-to-one communication is performed. In the vending machine PHS connection device, since the parent device and the child device enter between the center device and the vending machine, all the control data received by the parent device from the center device is directly transferred to the child device. . As a result, the transfer of the control data increases the communication load in the group, and hinders the transfer of the sales data.

Further, the conventional vending machine PHS connection device uses either a data communication using a deemed voice using a modem which has been used before or a PIAFS communication which is a newly defined 32 Kbps digital communication system. Was to communicate. The deemed voice communication and the PIAFS communication cannot be connected to each other as they are. Therefore, P
Sales data of vending machines of a group using IAFS communication could not be collected by a portable center device using deemed voice communication.

In the conventional vending machine PHS connection device, when communication between the center device and the parent device is performed by transceiver communication, PIAFS communication is used if the intra-group communication is PIAFS communication, and PIAFS communication is used if the intra-group communication is deemed voice communication. , Was performed by deemed voice communication. PHS
In transceiver communication between telephones, there is no incoming call information necessary for automatic determination of the communication system type. Therefore, it is impossible to automatically determine whether the communication is the PIAFS communication or the deemed voice communication. Transceiver communication within a group is limited to either PIAFS communication or deemed voice communication. Therefore, when communication between the center device and the parent device is performed by transceiver communication, it cannot be performed by deemed voice communication when the intra-group communication is PIAFS communication, and performed by PIAFS communication when the intra-group communication is deemed voice communication. I couldn't do that.

In the conventional vending machine PHS connection apparatus, power is supplied to all circuits even during a standby time during which no communication is performed. It is good if the power is supplied from the vending machine, but if the child device is installed away from the vending machine for relaying only and is powered by a battery, the battery is severely depleted and frequent manual operations are required. Had to change batteries.

[0014]

Therefore, in order to solve the above-mentioned problems, in a vending machine PHS connection device of the present invention, the collection time added to the sales data received from the child device by the parent device and the collection time are added. Then, a comparison is made with the collection time of the sales data stored in the parent device, and if the newly received sales data is older, the newly received sales data is not stored in the parent device. However, in order to prevent the accumulation of sales data from being stopped when the clock of the child device is delayed, the sales data received during a specific time period in the day set in the parent device is unconditionally set. Configure to accumulate. With this configuration, even if it takes time to transfer the sales data from the child device, it is possible to prevent the new sales data stored in the parent device from being erased by the old sales data.

Further, in the vending machine PHS connection device of the present invention, a confirmation command is transmitted to the external modem at regular intervals, and if there is no response thereto, a switch for controlling the power supply of the external modem is provided. Is provided with a circuit for turning off and on again. With this configuration, even in an unmanned vending machine PHS connection device, automatic recovery from the hang-up state of the external modem can be performed.

Further, in the vending machine PHS connection device of the present invention, the control data received from the center device is stored in the parent device, and compared with the control data newly received from the center device. In such a case, it is configured not to transfer to the child device. With this configuration, the control data received from the center device can be transferred to the child device only once, and the amount of data transferred between the parent device and the child device can be reduced.

Further, in the vending machine PHS connection device of the present invention, means for automatically judging voice communication as PIAFS communication based on information representing either of the received information and switching of the communication circuit. Means. With this configuration, it is possible to automatically determine which method to use for each communication and perform switching to enable both types of communication, and to connect to an old type center device that can only perform deemed voice communication. Enable.

Also, in the vending machine PHS connection device of the present invention, a specific telephone number is registered in the parent device, and the telephone number received by transceiver communication is compared with the registered telephone number, and if they match, the group is determined. It is configured to communicate by a method other than the communication method used in the inside. With this configuration, when communication between the center device and the parent device is performed by transceiver communication, communication within the group is P
The deemed voice communication can be performed even in the IAFS communication, and the PIAFS communication can be performed even in the deemed voice communication in the group.

Further, in the vending machine PHS connection device of the present invention, means for issuing a power saving start signal from the main control unit to the power control unit when the power saving mode is set, and means for cutting off power supply to the main control unit. And means for issuing a start signal from the PHS telephone when a call is received from the other party, means for detecting the start signal by the power control unit, and means for supplying power from the power control unit to the main control unit. The configuration was adopted. With this configuration, it is possible to prevent the battery from being consumed during the standby time and to prolong the battery replacement time.

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

(First Embodiment) In a first embodiment of the present invention, the collection time added to the sales data sent from the child device is the same as the collection time of the sales data stored in the parent device. The vending machine PHS connection device does not accumulate the received sales data when it is older than the collection time, and accumulates the sales data received in a specific time zone unconditionally.

FIG. 1 is a block diagram of a vending machine PHS connection device according to a first embodiment of the present invention. FIG. 2 is a diagram showing a processing flow of the vending machine PHS connection device.
The vending machine PHS connection device 1 is a PIAFS compatible PH
An S telephone 2 is provided. Vending machine connection cable 3
Is a signal cable for controlling the vending machine 5 and collecting various data of the vending machine 5. The power cable 4 connects the vending machine 5 to the vending machine PHS connection device 1
Cable to supply power to the Power supply is + 8V
Or at + 24V, the power consumption is about 2.4W. The modem unit 7 is a modem for performing deemed voice communication with the PHS telephone 2. A signal line from the modem unit 7 is connected to an earphone microphone terminal of the PHS telephone 2. The deemed voice communication is based on CCITT V.22bis, and the communication speed is 2
400 bps. The adapter unit (PS-ADP unit) 8
It is connected to the 16-pin terminal and charging terminal of the HS telephone 2, and has a 16-bit CPU,
It has a KB work memory and 8KB EEPROM, and controls outgoing and incoming calls, PIAFS communication and power supply. The control section 9 controls the entire vending machine PHS connection device 1 and includes a 16-bit CPU, a 256 KB program memory, a 256 KB work memory, a maintenance display device, and a keyboard.

The child device collects sales data including sales data and inventory data of automatic sales once an hour,
The collection time is added, and the data is transmitted to the parent device. Sales data is absolute value data such as amount and quantity, not differential data, etc., and it is data that can be understood independently, so even if past sales data is lost due to some kind of failure, it is exceptionally usable for future sales data There is no hindrance.

The parent device stores the sales data received from the child device in a memory, and transmits a group of sales data to the center device when requested by the center device. One data is about 4KB, and it becomes 200KB for 50 cars. Since it is expensive to provide a large-capacity memory in the parent device, a memory having a capacity capable of storing sales data of the child devices one by one is provided so that only the latest sales data is always stored.

A maximum of 50 child devices can be connected to one parent device. If the number of child devices increases and the relay relationship between the child devices becomes more complicated, the effective transfer speed will be extremely reduced if any communication failure occurs in the middle of the communication route and communication is performed on the bypass route. In some cases, it may take an hour or more for the sales data to arrive. As a result, sales data from the child device does not reach the parent device within the cycle, and sales data in the next cycle reaches the parent device first. Since the parent device cannot be equipped with a lot of memory, only one sales data can be obtained per child device. When old sales data arrives later, a situation occurs in which the latest sales data cannot be collected. In order to avoid this, only the latest sales data will be accumulated.

According to the processing flow of FIG. 2, the vending machine P
The operation of the HS connection device will be described. When the parent device receives the sales data from the child device, it checks whether the sales data from the child device is already stored in the parent device. If not, the received sales data is stored in the parent device. If the sales data from the child device has already been stored in the parent device, the current time is checked. If the current time is within the unconditional data storage time zone, the received sales data is stored in the parent device. This is to avoid the danger that all sales data will be discarded if the clock of the child device is significantly delayed for some reason.

If the current time is not within the unconditional data storage time zone, the collection time of the received sales data is checked. If the sales data has a collection time later than the collection time of the sales data received last time, the sales data is stored in the parent device. If the sales data has a collection time older than the collection time of the sales data received last time, the sales data received this time is discarded.

As described above, in the vending machine PHS connection apparatus according to the first embodiment of the present invention, the collection time of the sales data is determined, and if the sales data is older than the stored data, the storage is not performed. The data received during the time zone is configured to be stored unconditionally, and if the old sales data arrives at the parent device later than the new sales data, it will be discarded, so the new sales data will not be erased, Since a time zone for storing data is provided, all data is not discarded.

(Second Embodiment) In a second embodiment of the present invention, a confirmation command is sent to an external modem at regular intervals, and if there is no response to the confirmation command, the external Vending machine PHS that resets the external modem by turning off and on the attached modem
It is a connection device.

FIG. 3 is a block diagram of a vending machine PHS connection device according to a second embodiment of the present invention. FIG. 4 is a diagram showing a processing flow of the vending machine PHS connection device.

In the vending machine PHS connection device 1, PHS
An external modem 12 for a wired line is used for communication with a center device having only a wired line, or for use in a place without a PHS base station. And have a communication department. In the PIAFS communication, an ISDN line is required for the center device, and there is a center device that is not connected to the ISDN line and uses only deemed voice communication. Therefore, it is necessary to enable communication with such a center device. .

The external modem 12 is a modem called an "intelligent modem" and has an AA type NCU (automatic transmission / automatic reception type NCU). This type of NCU control method is based on CCITT V.25 and CCITT V.25.
There are methods using ITT V.25bis or Hayse AT command. CCITT V.25bis is compatible with CCITT V.24 (RS232C)
This is a method for controlling an A-type NCU. The Hayse AT command is called an "AT command" because the command always has "AT" (meaning Attention) at the beginning of the command. In these methods, control such as an automatic calling procedure is performed using data lines for transmission and reception. Since a response is returned to the control command, it is possible to determine whether the modem is operating normally by monitoring the response.

When the external modem 12 is used, the external modem 12 may run out of control for some reason and enter a hang-up state in which the external modem 12 does not operate. In such a state, resetting cannot be performed from the vending machine PHS connection device 1 side.

According to the processing flow of FIG.
The operation of the HS connection device 1 will be described. The control unit 9 sends an AT command to the external modem 12 and waits for a response. If there is a response from the external modem 12 within a predetermined time, it waits for three minutes and sends out the AT command again. External modem 12 within a predetermined time
If there is no response from the external modem 12, a command to turn off the switch 13 for controlling the power supply of the external modem 12 is issued, and the power supply of the external modem 12 is temporarily cut off. The external modem 12 is reset by turning on the power of the external modem 12 again. Thereafter, the operation of transmitting the AT command is repeated every three minutes. External modem 12
If is compliant with CCITT V.25bis, you can monitor the response with the command in the same way.

As described above, the vending machine PHS connection apparatus according to the second embodiment of the present invention sends a confirmation command to the external modem at regular intervals, and responds to this within a fixed time. If there is no external modem, the external modem is turned off, turned on, and reset, so that even if the external modem becomes abnormal, it can be automatically restored.

(Third Embodiment) In a third embodiment of the present invention, control data received from a center device is stored in a parent device, and when new control data is received, the stored control data is stored. This is a vending machine PHS connection device in which if new control data is all the same as stored control data, it is not transferred to the child device.

FIG. 5 is a diagram showing a processing flow of the vending machine PHS connection device according to the third embodiment of the present invention. The hardware configuration of the vending machine PHS connection device is the same as the block diagram of FIG.

When the parent device receives the data from the center device, it checks whether control data is included. If there is no control data, no data is transferred to the child device. If control data is included, it is checked whether the control data is included in the previously received data. If there is no control data in the data received last time, the control data received this time is transferred to the child device. If there is control data in the previously received data, the previous control data and the current control data are compared, and if the control data is all the same, the data is not transferred to the child device. If there are different control data, all the received control data are transferred to the child device.

Normally, sales data is collected by calling the parent device from the center device, but when an abnormal situation such as failure occurs or the product is out of stock, the vending machine sends the sales data to the center device. It is necessary to send trouble data etc. by calling. Therefore, control data is transmitted from the center device to the vending machine PHS connection device to instruct what to do. However, sending the same control data from the parent device to the child device only increases the traffic and hinders the transfer of the sales data. Therefore, the same control data should not be sent from the parent device to the child device. . However, if even one of the four types of control data records is different, all are sent to ensure reliability.

As described above, in the vending machine PHS connection device according to the third embodiment of the present invention, the means for accumulating the control data received from the center last time in the parent device and the means for comparing with the new control data are described. Means for judging whether the data should be transferred to the child device, and means for preventing the data from being transferred if the data is the same. Even if the same control data is continuously sent from the center, the child device , Traffic within the group is reduced and transfer of sales data is not hindered.

(Fourth Embodiment) In a fourth embodiment of the present invention, a vending machine which regards PIAFS communication, automatically determines voice communication from incoming information, and switches between a modem unit and an adapter unit. It is a PHS connection device.

FIG. 6 is a diagram showing a processing flow of the vending machine PHS connection device according to the fourth embodiment of the present invention. The hardware configuration of the vending machine PHS connection device is the same as the block diagram of FIG.

In order to enable connection with an old type center device that can only perform deemed voice communication and connection with an old type vending machine PHS connection device that can only perform deemed voice communication, deemed voice communication and PIAFS communication are required. Must be able to perform both communications. In this case, it is necessary to determine which communication method is used for communication for each communication. When the public PHS or the self-owned PHS is used, information indicating the type of the communication system is included in the received information, and the switching can be performed by automatically determining this. When an incoming call is received, the PHS telephone notifies the control unit of the type of communication via the PS-ADP unit. The control unit makes a determination by looking at the signal of which communication type.

If the incoming call type is deemed voice, a command for setting deemed voice communication is transmitted, a built-in modem is negotiated, and deemed voice communication is performed. If the incoming call type is not deemed voice, a PIAFS communication setting command is transmitted, PIAFS negotiation is performed, and P
IAFS communication is performed.

As described above, in the vending machine PHS connection apparatus according to the fourth embodiment of the present invention, it is assumed that the voice communication is regarded as the PIAFS communication and is automatically determined based on the information received and the switching is performed. , It is possible to automatically determine and communicate with the PIAFS communication.

(Fifth Embodiment) In a fifth embodiment of the present invention, when a call is received by transceiver communication, the telephone number of the caller is compared with a specific telephone number registered in the parent device. , A vending machine PHS connection device that communicates with a system other than the communication system used in the group when they match.

FIG. 7 is a diagram showing a processing flow of the vending machine PHS connection device according to the fifth embodiment of the present invention.

The parent device and the center device may communicate by deemed voice communication, and the parent device and the child device may need to communicate by PIAFS communication, and vice versa. According to the PHS standard, the type of communication cannot be determined in transceiver communication.
Therefore, in the transceiver communication, the communication type is determined based on the telephone number by using the fact that the telephone number is transmitted.

When PIAFS communication is performed within the group, the parent device extracts the received transceiver number and compares it with the set number. If they match,
A command for setting the deemed voice communication is transmitted, the internal modem is negotiated, and the deemed voice communication is performed. If the numbers do not match, a PIAFS communication setting command is transmitted, PIAFS negotiation is performed, and the PIAFS is negotiated.
AFS communication is performed.

This flow chart shows that PIAFS
In the case where communication is performed, but in the reverse case, that is, when performing deemed voice communication in a group, the parent device extracts the transceiver number that has arrived,
Compare with the set number. If they match, PI
An AFS communication setting command is transmitted, PIAFS negotiation is performed, and PIAFS communication is performed. If the numbers do not match, a command for setting the deemed voice communication is transmitted, the internal modem is negotiated, and the deemed voice communication is performed.

As described above, in the vending machine PHS connection device according to the fifth embodiment of the present invention, a specific telephone number is registered in the parent device, and when a call is received by the transceiver, the received telephone number is stored in the parent device. In comparison, if they match, communication is performed by a method other than the communication method used in the group. Therefore, even in transceiver communication, communication can be performed by switching communication methods.

(Sixth Embodiment) In a sixth embodiment of the present invention, when a power saving mode is set, a power saving start signal is sent from the main control unit to the power control unit to supply power to the main control unit. If supply is cut off and a call is received from the other party, PH
This is a vending machine PHS connection device that issues a start signal from the S telephone and restarts power supply from the power control unit to the main control unit.

FIG. 8 is a block diagram showing the configuration of a vending machine PHS connection device according to a sixth embodiment of the present invention.

In the power supply section 11, a power supply from a battery or the like is 5V
And supplies it to the PHS telephone 2 and the power control unit 10. The power control unit 10 supplies 5 V to the main control unit 6, and outputs a power saving start signal (5 V) from the main control unit 6.
SON signal), and controls 5V to the main control unit 6. The main control unit 6 outputs a power saving start signal (5VSON signal) and turns off the 5V power supply when a power saving mode such as a standby mode is set. When the PHS telephone 2 receives the call, it issues an activation signal (ADPWUP signal) to the power supply control unit 10 to restore the 5V power supply to the main control unit 6. PH
The power of the S telephone 2 is always supplied.

Although a current of about 300 mA flows during normal operation, the current is reduced to 10 mA in the power saving mode, so that the life of the battery can be greatly extended.

As described above, in the vending machine PHS connection apparatus according to the sixth embodiment of the present invention, when the power saving mode is set, the power saving start signal is output from the main control unit to the power supply control unit to perform the main control. The power supply to the main unit is cut off, and when a call is received from the other party, a start signal is output from the PHS telephone to the power control unit, and the power supply from the power control unit to the main control unit is restarted. Power consumption can be reduced.

[0063]

As described above, according to the present invention, the collection time added to the sales data from the child device is compared with the collection time of the sales data stored in the parent device, and the old sales data is compared. Since it is configured to discard when it arrives at the parent device later than new sales data, the effect is obtained that the latest sales data can always be stored.

Also, a confirmation command is sent to the external modem, and if there is no response, the power switch of the external modem is turned off and on, so that even if the external modem becomes abnormal, it can be automatically restored. Is obtained.

Further, the parent device compares the previous control data received from the center device with the new control data, and if the data is the same, does not transfer it to the child device.
Even if the same control data is continuously transmitted from the center device, it is not transferred to the child device, so that an effect of reducing traffic between the parent device and the child device can be obtained.

Further, since the voice communication is regarded as the PIAFS communication and automatically determined and switched, the PIAFS communication is performed.
An effect is obtained in that voice communication can be automatically determined and communicated assuming that the communication is S communication.

When the telephone number received by the transceiver communication matches a specific telephone number registered in the parent device, communication is performed by a method other than the communication method used in the group. The effect that the communication method can be switched to perform communication even in transceiver communication can be obtained.

Further, when the power saving mode is set, the power supply to the main control unit is cut off, and when a call is received, a start signal is output from the PHS telephone and the power supply unit supplies power to the main control unit. Therefore, the effect of reducing power consumption during standby can be obtained.
