Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic transmission device capable of transmitting a start signal from a plurality of externally connected terminal devices such as meters or an internal clock start, and particularly to a priority when a plurality of transmission factors are duplicated. Regarding operation.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 2, an automatic transmitter of this type has a meter start signal detecting section 2 for detecting a start signal from an externally connected meter 1 and for directly sending a call request signal. A transmission control unit 4 for controlling transmission to the line 3 in response to a transmission request signal transmitted from the activation signal detection unit 2
And a data through transfer unit that realizes communication between the meter 1 and the communication partner by through transfer via the device after connecting the communication partner and the device via the line 3 by the call control operation of the call controller 4. 5 and. The meter start signal detection unit 2 and the data-through transfer unit 5 are combined to form a data-through transfer meter interface unit, but this data-through transfer meter interface unit does not participate in the meter information of the meter 1 at all. By simply detecting the activation signal from the meter 1 and establishing the link between the meter 1 and the communication partner via the line 3, the subsequent data communication contents are also entrusted to the meter 1 and the communication partner.

On the other hand, a start signal from another meter 6 connected to the outside is detected by the meter start signal detecting section 7 and transmitted to the meter side transmitting / receiving section 8. The meter-side transmitting / receiving unit 8 absorbs the meter information corresponding to the activation signal from the meter 6 by performing transmission / reception operation with the meter 6 in response to detection of the meter activation signal. After confirming that the meter information transmitted and received by the meter-side transmitting / receiving unit 8 has a predetermined value, the meter information storage unit 9 is notified of the meter information. When this meter information is stored in the meter information storage unit 9, the meter information storage unit 9 sends out a transmission request signal. The transmission control unit 4 also controls transmission to the line 3 in response to the transmission request signal sent from the meter information storage unit 9. After the transmission control operation of the transmission control unit 4 connects the communication partner with this apparatus via the line 3, the line side transmission / reception unit 10 communicates with the communication partner. That is,
The meter information storage unit 9 notifies the communication partner of the meter information of the meter 6 that has been downloaded and stored in advance.
The meter start signal detection unit 7, the meter-side transmission / reception unit 8, the meter information storage unit 9, and the line-side transmission / reception unit 10 are combined to form a data-integrated meter interface unit. Unlike the data-through transfer meter interface part, the built-in data meter interface part forms two independent transmission / reception systems for communication between the meter and this device and communication between this device and the communication partner, and temporarily stores them inside. It indirectly connects the meter to the communication partner via the meter information.

The transmission control section 4 performs a transmission control operation for the earliest one of the transmission request signal from the data through transfer interface section and the transmission request signal from the data built-in meter interface section.

When the call origination control unit 4 starts a call origination control operation corresponding to one of the call origination request signals, the next call origination request signal is not accepted until this operation is completed.

Here, as an example of a transmission requesting unit that independently receives a plurality of transmission factors and transmits a transmission request signal, one data through transfer unit and one data built-in meter interface unit are provided. ..

[0007]

However, in the above-mentioned configuration, even if the transmission factor from the data-equipped meter interface section has an important content that requires urgent attention, the data-through transfer meter interface can be quickly and instantly. When the transmission request signal from the communication section is transmitted, the transmission control section receives the transmission request signal from the data through transfer interface section, and there is a problem that the importance of the transmission factor is not reflected at all. The present invention solves such a conventional problem. For example, a transmission request signal from a data built-in meter interface section that stores meter information is prioritized over a transmission request signal from a data through transfer meter interface section that does not store meter information. It is an object of the present invention to provide an automatic transmission device that performs a transmission control operation according to the importance of a reception transmission request.

[0008]

In order to solve the above-mentioned problems, an automatic transmission device of the present invention comprises a plurality of transmission requesting units for transmitting a transmission request signal when requesting transmission to a communication partner via a line. , A transmission priority switching unit that selects the transmission request signal with the highest priority according to a predetermined priority for a plurality of transmission request signals transmitted from this transmission request unit, and a transmission priority connected to this transmission priority switching unit. The transmission control unit performs a transmission control operation to the line according to the transmission request signal selected by the switching unit.

[0009]

According to the present invention, when the call origination request signals are simultaneously transmitted from the plurality of call origination request units, the present invention selects the call origination request signal having the highest priority and determines the origination corresponding to the event. The control operation is performed in order.
That is, the transmission control for a transmission factor having a high degree of urgency is always transmitted to the communication partner earlier.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. In FIG. 1, blocks having the same functions as those shown in the conventional example are given the same numbers.

In FIG. 1, reference numeral 2 denotes a meter start signal detecting section for detecting a start signal from an externally connected meter 1 and directly sending a call origination request signal, and 5 after connection with a communication partner via a line 3. It is a data through transfer unit that realizes communication between the meter 2 and the communication partner by through transfer. Similar to the conventional example, the meter start signal detection unit 2 and the data through transfer unit 5 are combined to form a data through transfer meter interface unit, and this data through transfer meter interface unit is not involved in the meter information of the meter 1 at all. .. Simply detect the start signal from the meter 1,
Only by establishing a link between the meter 1 and the communication partner via the line 3, the subsequent data communication contents are also entrusted to the meter 1 and the communication partner. On the other hand, a start signal from another meter 6 connected to the outside is detected by the meter start signal detecting section 7 and transmitted to the meter side transmitting / receiving section 8. The meter-side transmitting / receiving unit 8 absorbs the meter information corresponding to the activation signal from the meter 6 by performing transmission / reception operation with the meter 6 in response to detection of the meter activation signal. After confirming that the meter information transmitted and received by the meter side transmitting / receiving unit has a predetermined value, the meter information is transmitted to the meter information storage unit 9. When this meter information is stored in the meter information storage unit 9, the meter information storage unit 9 sends out a transmission request signal. Reference numeral 4 denotes a call origination control unit for performing a call origination control operation to the line 3 in response to a call origination request signal sent from the meter information storage unit 9. Transmission control unit 4
After the connection with the communication partner via the line 3 is performed by the call origination control operation, the line side transmitting / receiving unit 10 communicates with the communication partner.
That is, the meter information storage unit 9 notifies the communication partner of the meter information of the meter 6 that has been downloaded and stored in advance. Similar to the conventional example, the meter start signal detection unit 7, the meter side transmission / reception unit 8, the meter information storage unit 9 and the line side transmission / reception unit 10 are combined to form a data built-in meter interface unit. Unlike the data through transfer meter interface unit, the built-in data meter interface unit forms two independent transmission / reception systems for communication between the meter and this device and communication between this device and the communication partner.
The meter and the communication partner are indirectly connected via the meter information that is stored internally.

Reference numeral 11 is connected to the meter activation signal detection unit 2 in the data through transfer meter interface unit, the meter activation signal detection unit 7 and the meter information storage unit 9 in the data built-in meter interface unit, and from the meter activation signal detection unit 7. Is a transmission priority switching unit that prohibits the transmission request signal from the meter activation signal detection unit 2 while either the activation signal of the above or the transmission request signal indicating that the predetermined meter information is built into the meter information storage unit 9 is input. , Active-H, one AND gate and one NOR as shown in the figure.
It can be represented by a logic circuit composed of gates.

Here, the call origination control unit 4 performs the call origination control operation for the earliest one of the call origination request signal from the call origination priority switching unit 11 and the call origination request signal from the data built-in meter interface unit.

In the above configuration, the transmission priority switching unit is operated until the meter information from the meter 6 connected to the data-equipped meter interface unit is sucked up and stored, and the transmission control operation by the event is completed or until it is judged that there is no transmission request. Reference numeral 11 suppresses transmission control by activation from the meter 1 connected to the data through transfer meter interface unit. In addition, when the transmission request event from the data built-in meter interface section and the transmission request event from the data through transfer meter interface section overlap, the transmission from the data internal meter interface section is given priority and the reception transmission control operation is performed. Therefore, there is an effect that the start-up signal from the meter 1 connected to the data through transfer meter interface unit does not damage the built-in meter information in the built-in data meter interface unit. The data through transfer, which has a lower priority than the transmission request from the built-in data meter interface section, does not need to have built-in meter information, so the transmission control operation is postponed by the transmission priority in the built-in data meter interface section. Even if it becomes, there is no inconvenience in operation.

Here, as an example of a transmission requesting unit for individually receiving a plurality of transmission factors and transmitting a transmission request signal, one data through transfer unit and one meter built-in data meter interface unit are provided. Also in this case, the transmission priority switching unit 11 accepts only one of the transmission request signals sent from the individual data through transfer meter interface units or the built-in data meter interface units, which has the highest priority, based on a predetermined transmission priority order. It is a thing.

Further, although the number of lines is one and the number of call requesting units for transmitting a call request signal is two here, the number of lines may be two or more or the number of call requesting units may be three or more. It is not necessary that the number of types of call origination request signals that are prioritized for is not one.

[0017]

As described above, according to the automatic transmission device of the present invention, the following effects can be obtained. (1) When a call request signal is sent from a plurality of call request units at the same time, it is possible to notify the communication partner earlier if there is a call factor with a higher degree of urgency, so emergency information such as security can be sent earlier. There is an advantage that it can be notified. (2) Similarly, of the outgoing call requests from the terminal device connected to the automatic transmission device, if the priority is increased as the amount of outgoing data is large, the terminal device or the automatic transmission device itself should store the priority. The data memory capacity can be kept small.
