In addition, heat is easily generated even where ultra-high voltage power such as an underground electric power supply is supplied, which may cause many problems due to high heat.

As such, since high-voltage electrical connections often generate heat at the surface where they are not exposed, it is virtually impossible for a person to visit these places and measure and measure the temperature. Therefore, in general, there is a problem that must be found and acted after the occurrence of the problem.

1 is a view showing a measurement temperature wireless transmission control system according to an embodiment of the present invention.

As shown in FIG. 1, a system for measuring temperature wireless transmission according to an embodiment of the present invention includes a temperature measuring unit 102, a signal receiving unit 104, a signal transmitting unit 106, a timer 108, and a controller 110. Include.

The temperature measuring unit 102 receives a temperature measuring command and measures temperature data. The temperature measurement command is received from the controller 110.

The signal receiver 104 receives a transmission signal transmitted from the outside. The transmission signal is received from an external device, i.e., a measurement temperature collection control device that monitors and collects temperature of the measurement temperature wireless transmission control system of the present invention. This device collects the temperature measurement data from the measurement temperature wireless transmission control system installed in multiple places and collects the measurement temperature to prevent and control radio collisions that may occur when multiple measurement temperature wireless transmission control systems simultaneously transmit the measurement temperature. It is a control device.

The signal transmitter 106 transmits temperature data. The signal transmitter 106 may also transmit the temperature data to a measurement temperature collection control device that collects temperature measurement data from a measurement temperature wireless transmission control system installed at a plurality of places.

In the present invention, the signal receiver 104 and the signal transmitter 106 that transmit and receive wirelessly can achieve low power and low cost by using a wireless transmit / receive module such as ZigBee.

The timer 108 transmits a wakeup signal when a predetermined time passes. The designated time is specified and set by the controller 110, and a wakeup signal generated after the designated time is transmitted to the controller 110.

At this time, the controller 110 controls the signal transmitter 106 to wirelessly transmit temperature data measured by the temperature measurer 102 when the transmission signal received by the signal receiver 104 satisfies a predetermined condition. Here, the predetermined condition means whether the ID information included in the transmission signal satisfies the predetermined ID, that is, the local ID (ID of the corresponding measurement temperature wireless transmission control system).

Multiple measurement temperature radio transmission control systems installed in various places each have a unique local ID, indicating which measurement temperature radio transmission control system should transmit temperature data when the transmission signal is transmitted wirelessly.

The controller 110 sets the timer 108 to control the temperature data so that the signal transmitter 106 transmits wirelessly, and then the timer 108 sends a wakeup signal when a predetermined time passes. The predetermined time means a time interval for receiving the measurement temperature from each measurement temperature wireless transmission control system. For example, an external measurement temperature collection control device that wants to receive measurement temperature from 120 measurement temperature radio transmission control systems receives the measurement temperature from different measurement temperature radio transmission control systems every 15 seconds. The measured temperature can be transmitted.

In this embodiment, the control unit 110 sets the predetermined time of 30 minutes to the waiting time of the timer 108 and cuts off the power of the temperature measuring unit 102, the signal receiving unit 104, and the signal transmitting unit 106. It can prevent the power consumption that can occur during.

If the transmission signal received by the signal receiver 104 does not satisfy a predetermined condition, the waiting time is calculated. For example, suppose that 120 measurement temperature wireless transmission control systems each have ID information ranging from 1 to 120, and an external measurement temperature collection and control device that transmits a transmission signal is sequentially transmitted at 15 second intervals. At this time, if the local ID of the current system is 10 and the ID information of the received transmission signal is 120, the calculated waiting time is calculated as 15 seconds * 10 and becomes 150 seconds. That is, after 150 seconds, my system local ID is transmitted in a transmission signal.

At this time, the controller 110 sets the timer 108 so that the timer 108 sends a wake-up signal when the waiting time calculated as described above flows, and the temperature measuring unit 102, the signal receiving unit 104, and the signal transmitting unit 106 are provided. To prevent power consumption.

When the controller 110 receives the wake-up signal from the timer 108, the control unit 110 supplies the cut-off power to the temperature measuring unit 102, the signal receiving unit 104, and the signal transmitting unit 106, and then issues a temperature measuring command to the temperature measuring unit. Send to 102.

2 is a flowchart illustrating a step of measuring and transmitting temperature by a measurement temperature wireless transmission control system according to an exemplary embodiment of the present invention.

As shown in FIG. 2, when the system is turned on when the wake-up signal is received or the power is turned on, the temperature measuring unit 102 first measures temperature data (S202). At this time, the controller checks whether the transmission signal is received for 18 seconds after receiving the wake-up signal (S210) (S204), and if the transmission signal is received, checks the ID information included in the transmission signal (S206). In this embodiment, 18 seconds, but is not limited thereto.

If the transmitted ID information is the same as the local ID, the measured temperature data is transmitted using the signal transmitter 106 (S208), and the apparatus enters the standby mode for 30 minutes (S212). Standby mode means waiting for the timer 108 to send a wake-up signal after a predetermined time.

If the transmitted ID information is not the local ID, the waiting time is calculated (S214). Enters standby mode for the specified time as much as the calculated standby time. As described above, the standby mode means supplying only power necessary for the operation of the timer 108.

When the timer 108 sends a wake-up signal, the control unit 110 supplies power cut off to the temperature measuring unit 102, the signal receiving unit 104, and the signal transmitting unit 106 so that routines such as temperature measurement and transmission are performed. Do it again.

1 and 2 together with FIG. 3, a measurement temperature wireless transmission control method of a system including a temperature measuring unit 102, a signal receiving unit 104, a signal transmitting unit 106, and a timer 108 is a temperature control method. After the measuring unit 102 measures the temperature data (S302), and receives the transmission signal from the signal receiving unit 104 (S304), the ID information is checked (S306).

If the transmission signal is a predetermined condition, that is, the transmitted ID information is the local ID, the signal transmitter 106 controls the wireless transmission of the measured temperature data to an external measurement temperature collection control device (S308), and if a predetermined time passes, the timer. Set the timer 108 so that the 108 sends the wake-up signal to the control unit 110 and cuts off the power of the temperature measuring unit 102, the signal receiving unit 104, and the signal transmitting unit 106 and enters the standby state ( S310).

If the transmitted ID information is not the local ID, the waiting time is calculated, and if the waiting time passes, the timer 108 sets the timer 108 to send a wake-up signal, and the temperature measuring unit 102 and the signal receiving unit 104. In operation S310, the power supply of the signal transmitter 106 is cut off.

If the control unit 110 receives the wake-up signal from the timer 108 after the designated waiting time passes, the wake-up for supplying power to the temperature measuring unit 102, the signal receiving unit 104, and the signal transmitting unit 106 is supplied. The flow advances to step S312.

After the wake-up step (S312) is carried out again in the temperature measurement step (S302), the transmission signal receiving step (S304) in order to control the method to periodically transmit the measurement temperature.

The present invention realizes ultra-low power consumption of a measurement temperature wireless transmission control system using a battery using a wireless transmission / reception module such as ZigBee, and proposes a method for correcting a transmission sequential error of a measurement temperature wireless transmission control system and an initialization method thereof.

Receive data sequentially to prevent radio collisions and cut off all power except the timer in standby mode to realize ultra-low power saving of the wireless transmission control system.

As described above, the present invention corrects the sequential error between the various measurement temperature wireless transmission control system when the power is turned off and then on again during maintenance or operation of the measurement temperature wireless transmission control system, and local measurement is performed at a predetermined time point. The temperature can be initialized to transmit the measured temperature of the wireless transmission control system.
