Abstract

Temperature measurement data obtained by measuring the temperature of a cable clamp (31) by a temperature sensor (320) is radio-transmitted from a temperature sensing unit (32) at a predetermined timing, and the radio-transmitted temperature measurement data is received by a receiving station (5), classified by the temperature sensing unit number, and stored in a temperature measurement data storage area (502A). The temperature measurement data transmitted from twelve temperature sensing units (32) can be received by one receiving station (5).

Claims

1. A temperature monitoring device, comprising:

a data transmitting means that includes a temperature sensor to measure temperature of a monitored object, said data transmission means transmitting wirelessly a temperature measurement data based on said temperature;

a data storing means that receives said temperature measurement data to be transmitted wirelessly and stores said data a into a storing region; and

a data acquiring means that outputs a read command of said temperature measurement data to said data storing means to acquire said temperature measurement data from said storing region.

2. The temperature monitoring device according to claim 1, wherein:

said data transmitting means includes an identification number storing section that stores an identification number to distinguish said data transmitting means from the other data transmitting means, and a calculation section that calculates a transmission timing of said temperature measurement data including said identification number based on said identification number.

3. The temperature monitoring device according to claim 1, wherein;

said data storing means transmits wirelessly said temperature measurement data based on said read command transmitted wirelessly from said data acquiring means.

4. The temperature monitoring device according to claim 1, wherein:

said data storing means transmits wirelesely said temperature measurement data through a signal line based on said read command sent through said signal line from said data acquiring means.

5. The temperature monitoring device according to claim 1, wherein:

said data storing means includes a protocol control section that control a communication protocol used to connect with a communication network.

6. The temperature monitoring device according to claim 1, wherein:

said data acquiring means is a personal computer, a mobile phone or PDA (personal digital assistant) that can control a communication protocol used to connect with a communication network.

7. The temperature monitoring device according to claim 1, wherein:

said data acquiring means receives said temperature measurement data to be wirelessly transmitted from said data transmitting means.
