Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data communication device of a terminal device which is used, for example, in a package delivery system and automatically transmits data of the terminal device to a center of a host device.

[0002]

2. Description of the Related Art Generally, in a package delivery system, packages are collected and delivered at a distribution center or the like. In addition, each delivery center or the like is provided with a terminal device, data such as the number of packages and delivery destinations is registered in the terminal device, and this registration data is collectively transmitted to the center, which is a host device.

FIG. 2 is a flow chart showing a data transmission process of a terminal device in such a distribution center, and FIG. 2 (a) is a data registration process of the terminal device.
(B) shows data transmission processing to the center of the terminal device. First, as shown in FIG. 2A, the operator of the terminal device selects a process such as a cargo sending process or a cargo receiving process (step S1). For example, when the shipping process is selected, the operator inputs the shipping data, the shipping data, the shipping data, the identification data, etc. (step S2). Then, the terminal device checks whether or not the input data is appropriate data, that is, whether necessary data is prepared, conforms to the format, etc. (step S3), and if it is appropriate data, Register in the memory (step S4). Incidentally, when the load receiving process is selected in the process selection of step S1, it is not directly related to the present invention, and therefore the description thereof is omitted here.

Next, in the transmission process of the terminal device, the operator selects the transmission process and first checks whether or not the registration data to be transmitted is stored in the memory (step S11).
If the registration data is stored, the data transmission process is executed (step S12). Then, the terminal device checks whether this is a normal end (step S13). If the end is normal, the transmission process is ended, and if the end is not normal, the data transmission of step S12 is performed again. If there is no transmission data in step S11, the transmission process ends. By the data transmission process of such a terminal device, the data of the package delivery process can be collectively managed at the center, and the efficiency of the package delivery office work can be improved.

[0005]

However, as described above, since the data transmission processing of the terminal device is conventionally dependent on the operator's operation, for example, although the operator has data to be transmitted to the center, You may forget to send the data to the center. Therefore, in such a case, there is a problem that the center cannot accurately grasp the contents of the package delivery process, which hinders smooth delivery process.
Further, usually, a plurality of delivery centers and the like that perform data transmission processing to the center are provided, and the data transmission time tends to be concentrated in a certain time zone of the day. For this reason, the host computer of the center is often busy,
Since the load on the host computer is heavy and the transmission operation from the terminal device side cannot be performed smoothly, there is a problem in that the data transmission operation is forgotten from this point as well.

The present invention has been made in order to solve the above-mentioned conventional problems, and there is no data transmission omission on the side of the terminal device, and the host device can accurately grasp the data of the package delivery processing. An object of the present invention is to provide a data communication device.

[0007]

An apparatus according to the present invention includes a transmission time storage unit for storing a data transmission time designated by a host device managing a terminal device, and a registration data storage for storing data to be transmitted to the host device. Section, the time comparison means for comparing the current time and the data transmission time stored in the transmission time storage section, and the time comparison means, if the current time and the data transmission time match, the registered data storage section has not been stored. Transmission data detection means for detecting transmission data and transmission means for transmitting untransmitted data detected by the transmission data detection means to the host device are provided.

The present invention will be described in detail below with reference to the embodiments shown in the drawings.

FIG. 1 is a block diagram showing a data communication device of a terminal device of the present invention. The apparatus shown in the figure comprises a current time reading means 1, a time comparing means 2, a memory 3, a transmission data detecting means 4 and a transmitting means 5.

The current time reading means 1 has a function of reading the current time from a clock circuit described later and sending the current time signal to the time comparing means 2. Memory 3 is
It is composed of a random access memory or the like, and is provided with a transmission time storage unit 6 and a registration data storage unit 7. The transmission time storage unit 6 stores the data transmission time designated by the center that manages the terminal device. Registration data storage unit 7
Stores the data that the terminal device should send to the center, that is, the consignor data, consignee data, package data, identification data, etc., and the untransmitted registration number data is provided at the beginning of the storage area. There is. The time comparison unit 2 compares the current time from the current time reading unit 1 with the transmission time of the transmission time storage unit 6 of the memory 3, and when these times match, sends a time coincidence signal to the transmission data detection unit 4. It has a function to do. The transmission data detecting means 4 has a function of referring to the registration data storage section 7 when the coincidence signal from the time comparing means 2 is input, and reading out the untransmitted data when there is untransmitted data and outputting it to the transmission means 5. is doing. The transmitting means 5 is a communication control circuit that transmits untransmitted data to the center via a communication line.

FIG. 3 is a block diagram showing the configurations of the terminal device 10 and the center 20 as a host device. Terminal device 1

The processor 11 is a device constituting the present time reading means 1, the time comparing means 2, the transmission data detecting means 4 and the like shown in FIG. The clock circuit 12 is a circuit that outputs a current time signal.
The interrupt controller 13 is an interrupt control circuit that receives the current time signal from the clock circuit 12 and interrupts the processor 11 every one second. Next, the operation of the data communication device of the terminal device configured as described above will be described.

<< Time Setting Operation for Terminal Device >> Terminal Device 1
0 and the center 20 are connected by a call from the terminal device 10 via a communication line to exchange data. Terminal device 10
As the time setting data, the data of the m-th byte to the (m + p) th byte of the n-th block is transmitted from the center 20 to the terminal device 10 as the transmission time. FIG. 4 is a diagram showing this transmission time data format. That is, as shown in the figure, a plurality of transmission times (hours, minutes, seconds) are designated by the data in the n-th block. When the terminal device 10 receives this data,
The processor 11 stores the data transmission time of the terminal device 10 in the transmission time storage unit 6 in the memory 3.

<< Data Transmission Operation of Terminal Device >> FIG. 5 is a flow chart of the automatic data transmission operation of the terminal device 10. First, the processor 11 of the terminal device 10 receives an interrupt every 1 second by the interrupt controller 13. As a result, the current time reading means 1 of the processor 11 reads the current time from the clock circuit 12 and sends it as the current time signal to the time comparing means 2. When the time comparison means 2 receives this current time signal, the time comparison means 2 compares it with the transmission time stored in the transmission time storage section 6 (step S101), and if these times match, a coincidence signal is sent to the transmission data detection means 4. When it does not match, the process is terminated. When the coincidence signal from the time comparison unit 2 is input, the transmission data detection unit 4 reads the untransmitted registration number data located at the head of the registration data storage unit 7, and the value is 0, that is, the untransmitted registration data is the registration data. It is confirmed whether or not it remains in the storage unit 7 (step S102). As a result, if the untransmitted registration data does not remain, the process is terminated, and if the untransmitted registration data remains, the untransmitted registration data is sent to the center 2
0 (step S103). This transmission process is
The transmission means 5 performs the untransmitted registration data detected by the transmission data detection means 4.
