Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field to which the Invention Pertains The present invention performs reception, decoding, etc. of activation signals, and processes data transmission. Automatic meter reading terminal device with RII fflil section (2 related).

Prior Art Conventionally, an automatic meter reading terminal device is activated by a predetermined activation signal, converts the nitrate value of the meter into a predetermined format, and sends it out as a nausea signal. However, the control section 6111 of these operations and its instructions are integrated into an LSI or programmed on a 7-star RL) M, making it difficult to change.
? If you want to output the display or voice synthesis data from , or perform an operation such as adjusting a valve, the necessary logic or block will be lost.

OBJECTS OF THE INVENTION An object of the present invention is to eliminate these conventional drawbacks and provide a multifunctional automatic meter reading terminal device that is easy to expand and change.

EMBODIMENTS OF THE INVENTION The invention will now be explained with reference to the drawings. FIG. 1 is a block diagram of an embodiment of the present invention.

The transmission line 1 is a transmission line that transmits start signals, data written to the automatic meter reading terminals H and M, and data sent from the automatic meter reading terminals '&if, and the input and output lines may be separated into two pairs. It may be a pair of wires that are common to input and output, or may be a conductor wire that transmits current or pressure signals, or an optical fiber wire that transmits optical signals. The signal converter 2 converts the signal transmitted by the transmission line and the No. 45 inside the device, and converts the logic signal inside the device into a current, voltage, or optical signal using a photocoupler, transistor, light emitting diode, etc. It is a part that converts magnetic current, voltage, and optical signals into logic signals inside the device.

The serial/parallel converter 3 converts the serial signal sent from the signal converter 2 into a parallel signal, and the storage unit 4 stores and holds the converted received data. The storage unit 5 stores in advance basic commands for controlling the entire control unit 6. The control section 6 decodes the received signal and transfers it to the storage section 4 according to the commands and numerical values stored in the storage section 4 and the storage section 5C.

The parallel-to-serial converter 7 controls the transmission of the meter measurement value, and the parallel-to-serial converter 7
The parallel transmission data sent from the 481 converter 2 is converted into a serial transmission signal and sent to the No. 481 converter 2.

The meter value conversion unit 8 performs signal conversion for transmitting the meter value fPi value, which is the main purpose of the main +hIi meter reading terminal device, and converts the meter reading value 1 (1 value f: 4'+'t ”kν
A conversion process is performed to encode the memorized finger button positions of counters and meters into electrical signals or ULP codes such as BCJ) codes.

Ito light j ← layer effect two effects: Next, the effects of the book-'J, #i+i example configured as follows will be explained. FIG. 2 shows, as an example of a data transmission power format, the structure of data sent to this device 1C in a half-duplex start-stop mode, and FIG. 513 shows the bit structure of each data.

In Figure 2, S'['X(
Start of text) When 9 is received 1d, the signal conversion in Figure 1, -: l The start bit [2] and the stop bit [3] shown are removed and sent to the control section 6 shown in Figure 1.

When the reception of S 'L' In other words, the serial data 10 is the signal converter 2
The signals are then converted into parallel signals by the serial/parallel converter 3, and at the same time, the start bit 12 and stop bit 13 shown in FIG. When the ETX (, znd of text) 11 shown in is confirmed by the control unit 6, a still image 1 (j is the storage unit 4 (-) is transferred to the stored command group. Here,
The command group stored in the storage unit 4 and executed may be one that causes all required operations to be performed, or the command group that is stored in the storage unit 5 in advance and that causes several operations to be performed. You may also select .

Next, another practical example of the present invention will be explained with reference to FIG.

Components that are the same as those in the embodiment shown in FIG. 14 is a command/activation signal selection section. In this embodiment, a group of commands and a start signal are distinguished,
The command group is stored in the storage unit 4, but the operation is not activated. Activation of an action requires all other activation information.

The command group and the activation signal can be distinguished by, for example, changing 5TX9 in Figure 2 to the tongue ti command group and activation signal 16. If the product group and the activation signal are distinguished as in other embodiments, if the entire command group is memorized first, activation can be performed with just a simple activation signal, and the total tl-value of the meter can be transmitted to the terminal. If this is the main work of the device (- means that a group of commands for transmitting the measured value of the meter is stored in advance, and another group of commands is re-stored only when performing a special operation for testing or other purposes. This has the advantage of simplifying startup.Also, when changing the transmission operation of the value, the new 66 order group is
'l l- Just fix it. In this case as well, it is possible (i) to store a group of predicted instructions in advance in the storage unit 5-\.

As described in detail (2), the present invention uses 4+i4* to control operations by transmitting commands and numerical values from transmission lines.
Therefore, there is an effect that even operations that are not set in the device in advance can be performed by simply transmitting data without changing the circuit of the terminal device. Similarly, it is possible to provide many functions with a small number of components.

Furthermore, even if the function is to be changed in the future [self-cutting 1], it will be possible to do so with only the minimum necessary reduction of the road surface, such as retrofitting the interface section. For example, in a case where it becomes necessary to control the supply of water, t, f, etc., instead of using a small transmission scale, the operations necessary for the terminal device of the present invention may be necessary. (Secondly, on-the-spot C: This enables detailed control according to the situation.)

Furthermore, when outputting two-voice synthesized data to notify of outages or water outages, if all the threat synthesis data is created centrally and sent to the storage element in the terminal device of the present invention through the transmission line and output, It is possible to output various types of threats without preparing and displaying a threat synthesis unit or data for threat synthesis in the terminal device.In other words, the automatic meter reading terminal device configured as described above of the present invention is highly expandable. It is possible to construct a multi-Buddhist/Nohma device.
