Description

A transmitter-receiver of remote-manless measurement result for wire / wireless phone}

The present invention relates to a remote unattended measurement result transmitting / receiving device using a wired / wireless telephone terminal. Specifically, a dual tone multifrequency (DTMF) applied as a communication means in a wired / wireless telephone terminal and a telephone terminal. By the remote unattended measurement results are transmitted and received to realize the time, space, economic benefits and more stable communication status for transmitting and receiving the measurement results.

In order to check the real-time state of a specific object or space, various measurement equipments are involved, and the field of measurement is quite extensively physically, chemically, and spatially such as temperature, humidity, weight, distance, displacement, and altitude.

In order to perform measurement on a specific object in various fields as described above, a sensor corresponding to each condition is required, and such a sensor is ideally positioned to detect the current state of a specific object and to detect the data. Is installed.

In addition, the detected information is collected and provided to a public institution, a research institute, a specific company, etc., which require it.

In order to provide the information detected by the sensor as described above, conventionally, a communication line for transmitting data is mainly used, and this communication line is largely divided into a wired communication method and a wireless communication method.

First of all, the above-described wired communication method connects a cable for performing communication with a circuit in which a sensor is installed as a representative method to a desired location, such as a dedicated line and communication by LAN connection.

Such data transmission by wired communication converts the signal detected by the sensor into a signal suitable for communication, and transmits it through a dedicated line, a LAN cable, and the like. The temperature signal is converted into a digital signal by a converter or the like, and then converted into a specific frequency and transmitted.

In addition, the above-described wireless communication method is the most representative method such as communication by wireless transmission equipment equipped with a wireless LAN or a remote transmission equipment.

Such transmission by wireless communication, like a wired communication method, converts a signal sensed by a sensor into a signal suitable for wireless communication and transmits it to a transmitting device, and converts the transmitted signal into a specific frequency to a desired position. Will be sent.

The measurement result transmission / reception process according to the conventional wired / wireless communication method is subject to a considerable restriction on the place to be installed, that is, the space in the case of wired communication, for example, to measure the wind direction, wind speed, etc. of the ocean The measuring instruments (with sensors) must be installed at sea and connected via submarine cables.

Therefore, due to the excessive expenses and delays in working time, which are not practically used, wireline is limited only to the ground where communication lines can be easily installed. In particular, when the object to be measured and the measuring device to perform the detection by moving a number of locations, such a problem occurs that this wired communication method is not applicable.

In the wireless communication, when a plurality of measuring devices are to detect and detect various conditions such as temperature, humidity, and weight for a specific object, a unique frequency must be allocated to each measuring device, and a communication method is performed. In addition, considerable amount of time and money are consumed in the process of determining the type, and must involve various expensive equipment including an interface device for more stable communication against communication disturbances such as frequency interference between multiple measuring devices.

As a result, in order to perform the transmission / reception process of the measurement result by the wireless communication described above, there is a problem that a significant economic and time loss has to be taken.

The present invention was devised to solve the above-mentioned problems. As a means for transmitting / receiving measurement results, a wired / wireless telephone terminal is applied without a separate communication device, and a point where a measurement result for a specific object is desired. The object of the present invention is to provide a device for transmitting / receiving unattended remote measurement results.

It is done.

For reference, a dual tone multifrequency (DTMF) is numeric (signal) information transmitted from a telephone, and is used in an electronic exchange, and when a corresponding number of the telephone is pressed, a complex frequency signal is applied to the exchange, and the exchange decrypts the digital signal. It is a frequency signal system that is converted into information.

That is, the complex frequency code is an acoustic phenomenon in which different tone is expressed when a dial button of a general wired / wireless phone is pressed. When a specific frequency is assigned to a row and a row of the phone dial, each button is pressed. It is well known that has a unique complex frequency to be able to recognize and detect the number of the dial using it.

Hereinafter, with reference to the accompanying drawings an embodiment of the present invention to which the feature is applied will be described in detail.

1 is a block diagram showing a circuit configuration of a measurement result transmission / reception apparatus according to the present invention.

Referring to FIG. 1, the measurement result transmission / reception apparatus according to the present invention includes an input unit 10, a control unit 20 and 40, a communication circuit unit 30, and an output unit 50.

The input unit 10 includes a conventional key pad 11 for setting and inputting various conditions of a device, and a sensor 12 which is a measuring device for detecting and detecting a real-time state of a specific object.

Here, the sensor 12 has a plurality of objects to be detected or when a plurality of sensors are installed to detect and detect various conditions for a single object, as shown in FIG. The identification number is assigned.

The identification number is configured to be recognized by a complex frequency code which is a signal system of telephone communication to be described later.

The control unit 20 may be most commonly applied to a microprocessor for converting and controlling the detection signal input through the sensor 12 into a processing signal suitable for the device, the processing signal suitable for the device is input from the sensor 12 When the detected detection signal is analog, it is converted into a digital signal or a signal suitable for communication.

Here, the control unit 20 includes a signal processing unit 21 made of an A / D converter, an encoder, a decoder, etc. for converting the detection signal of the sensor 12 into a digital signal, a complex frequency code. And a timer 22 and a memory 23 for storing and outputting the detected signal and the converted signal for each time.

The communication circuit unit 30 includes a communication repeater 35 for relaying wired / wireless communication, and a transmission / reception circuit unit accompanying a side for detecting a specific object by the sensor 12 based on the communication repeater 35. A telephone terminal 31 having a telephone terminal 31, and a telephone terminal 33 having a transmission / reception circuit section 34 for receiving (if necessary) transmitting a measurement result by the telephone terminal 31; It is composed.

Each of the telephone terminals 31 and 33 can be most conveniently applied as a wireless mobile phone by default, and a wired telephone connection can be used as well as a wired telephone and a wireless mobile phone can be applied in common if space constraints are not considered. As such, the connection configuration and operation at this time are due to the conventional wired / wireless communication technology.

The output unit 50 is a PC terminal 51 (more specifically, a monitor, a printer, a speaker, etc.) or other display device for outputting the measurement result received through the telephone terminal 33 to the outside.

Here, the control unit 40 for converting the complex frequency code transmitted from the output unit 50 through the telephone terminal 33 into a processing signal suitable for the PC terminal 51 is provided, and the control unit 40 is It is apparent that a signal processor 41, such as an AD converter, an encoder, and a decoder, which converts the received signal, is included.

In addition, the control unit 40 is provided with a timer 42 and the memory 43 is configured to store time zone control and control status for the output of the measurement result value.

When the configuration as described above is summarized, the control unit 20 and the telephone terminal 31 on the side of detecting and detecting a specific object based on the communication repeater 35 become the configuration of the measuring unit 1, and outputs the measurement result. The telephone terminal 33, the control unit 40, and the output unit 2 are configured as a confirmation unit 2 for confirming the measurement result.

3 is a flowchart illustrating a communication process of the measurement result transmitting / receiving apparatus configured as described above, which starts with a request for a measurement result from the checking unit to the measuring unit.

Referring to FIG. 3, in order to confirm the measurement result, a communication is attempted by dialing the telephone terminal 33 of the checking unit 2 to the telephone terminal 31 of the measuring unit 1 (S10) and the control unit 20. In the measuring unit 1, it is determined whether the present status is available for communication (during a call by another call, an error of the device itself, etc.) (S20).

If the communication is not possible according to the determination, the setting of the timer 22 is confirmed (S21), and the dialing is attempted again according to the set time and number, or the communication is terminated after the proper number of times is dialed although not shown. .

On the contrary, when it is determined that communication is possible, the target data is requested, and the target data is inputted through the telephone terminal 31 of the complex frequency code for the identification number of any one of the plurality of sensors 12. The terminal 31 of the measuring unit 1 receiving the signal transmits the request signal to the control unit 20 (S30).

In response to the request signal, the control unit 20 selects data corresponding to the request, converts (decodes) the complex frequency code through the signal processing unit 21, and then verifies the unit 2 through the telephone terminal 31. It is transmitted to the side phone terminal 33. (S40)

In this case, the data is transmitted through the same process as in FIG. 4.

Referring to FIG. 4, when the data transmission requires the type of requested data, for example, data by the temperature sensor shown in FIG. 2, the controller 20 confirms that the input request signal is for the temperature sensor (S41). ) The information about the identification number "02" is output from the memory 23 (S42) and converted into a complex frequency code through the signal processor 21 to be output. (S43)

The data output in this way is input to the telephone terminal 31 and transmitted to the verification unit 2 (S44). Then, the check value data is transmitted to check whether the data is normal data (S45).

At this time, it is obvious that the data is numerical data on the measurement result. For example, if the complex frequency code corresponding to "12345 ..." is inputted to the telephone terminal 33 of the confirmation unit 2, For each numerical value, a complex frequency code of "87654 ...", which is a numerical value corresponding to nine's complement number in decimal number, is input together, and the numerical value corresponding to '9's complement number is check value data.

Thereafter, the data input through the telephone terminal 33 of the confirmation unit 2 is input to the control unit 40, wherein the above-mentioned digits are added to each of the digits "99999 ..." It is determined whether or not they match, and whether normal data is transmitted is determined (S50).

If the normal data is not input in the determination process, that is, if each digit does not become "99999 ...", the data is re-requested for the set number of times in the timer and the memory (S51). If the normal data is not transmitted even after performing the re-request, the error contents are output through the PC terminal 51. (S52)

When it is determined that the normal data is transmitted in the determination process, the control unit 40 ends the communication (S60) and converts the complex frequency code into a signal that can be processed by the PC terminal 51 through the signal processing unit 41 (encoding). After the signal processing, (S70) it is output to the screen, document, voice, etc. (S80).

FIG. 5 is a flowchart illustrating a process of transmitting / receiving a measurement result as shown in FIG. 4, in which a determination of transmission / reception of the measurement result is started by the measurement unit.

Referring to FIG. 5, a setting for transmitting / receiving at a predetermined time or a predetermined time interval by applying a timer 22 to the memory 23 of the measuring unit 1, types of measurement results to be transmitted for each time zone, and the like As the stored time, the timer 22, while counting the time (S10 ') when the set time reaches the control unit 20 performs the dialing of the telephone terminal 31 (S20').

While performing the dialing, the control unit 20 determines whether the current status is available for communication in the measuring unit 1 (during a call by another call, an error of the device itself, etc.) (S30 ').

If the communication is not possible according to the above determination, check the setting of the timer 22 (S31 ') and try dialing again according to the set time and number of times, or terminate the communication after dialing the proper number of times although not shown. If communication is possible, a series of processes of transmitting and processing the corresponding data of FIG. 4 are performed. (S40 to S80)

In the above-described measurement result transmitting / receiving process, the entire process is automated by the principle that a series of processes are performed by the control unit 20, 40. However, if the measurement result is to be confirmed at a time, the checking unit 2 In the checker directly communicates with the telephone terminal 31 of the measuring unit 1 it is possible to confirm the measurement results.

At this time, it is natural that the control unit 20 of the measurement unit 1 includes data capable of performing a normal ARS (automatic response service) function on the memory 23.

As described above, the present invention provides a benefit in terms of installation cost and time of the measurement result transmission / reception equipment by eliminating the need for expensive equipment by transmitting the measurement result to a desired point through a wired / wireless telephone terminal. In particular, the application of the wireless telephone terminal has the effect of eliminating the spatial constraints according to the mobility of the measuring device and the measurement object.

The present invention implements a process of converting the measured result into a complex frequency code applied to the communication means of the wired / wireless telephone terminal and transmitting the result to a desired point, thereby making the communication process of transmitting / receiving the measurement result more stable. It has the effect of improving the reliability of the user.
