Abstract

<P>PROBLEM TO BE SOLVED: To easily collect the recorded data in a short time by reducing the size and the cost of a sensor unit, and collectively recording the data transmitted from a plurality of sensor units in a master station. <P>SOLUTION: Any recorder is not mounted on a wireless transmission remote station 20, and the measurement data 11 is transmitted to a wireless reception master station 30 with the recorder 33 being mounted thereon through the wireless data 12. The wireless master station is preferably records the measurement data 11 from a plurality of wireless transmission remote stations collectively. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

  The present invention divides the wireless transmitter slave unit and the wireless receiver master unit that records data into each wireless transmitter slave unit at low cost, and easily collects data stored in the wireless receiver master unit. The present invention relates to a measuring apparatus that can be used.

  A device that records the temperature, humidity, and other sensors is used as a method to leave the state of the surrounding environment in the history of the distribution of transported goods. Recorded data is collected after the shipment arrives at the destination, and the history of the surrounding environment in circulation is obtained.

  However, a recording unit is mounted on each sensor, and the sensor recording device is expensive. If each sensor is mounted on a large amount of transported goods, it takes time and effort to collect data.

  The sensor recording device is expensive, and it takes time to collect recording data from a large number of sensor recording devices.

  The wireless sensor measurement device according to the present invention does not mount the recording unit on the sensor, but transmits the measurement result to the parent device on which the recording unit is mounted wirelessly.

The master unit records the measurement data from multiple sensors at once.

  As described above, by using a wireless sensor recording device, the sensor unit can be made smaller and cheaper, and the data transmitted from multiple sensor units is recorded in a batch by the master unit, so recording data is collected. Can be easily done in a short time.

  A wireless transmitter slave unit that transmits data from the sensor and a wireless receiver master unit that records data from multiple slave units have realized a low-cost sensor unit and a short recording data collection time.

  FIG. 1 is a block diagram of a radio transmitter slave for carrying out the present invention.

  FIG. 2 is a block diagram of a radio receiving master for carrying out the present invention.

  The wireless transmitter slave 20 includes a temperature / humidity sensor 21, a CPU 22, and a transmitter 23.

  The wireless receiver base unit 30 includes a receiver 31, a CPU 32, and a recording device 33.

  FIG. 3 is a diagram showing the configuration and operation of the wireless sensor measurement device of the present invention.

  The measured data 11 obtained by measuring the ambient environment 10 by the temperature / humidity sensor 21 in the wireless transmitter 20 is acquired by the CPU 22.

  The acquired information is transmitted as wireless data 12 using the transmitter 23.

  The CPU 32 acquires the wireless data received by the receiver 31 in the wireless reception base unit 30.

  The acquired information is stored in the storage device 33. Thereby, the measurement data 10 from the plurality of wireless transmission slave units 20 can be collectively recorded in the recording device 33 in the wireless reception master unit 30.

It is a block diagram of a radio transmitter slave having a function of the present invention. It is a block diagram of the radio | wireless receiver parent machine which has a function of this invention. It is a block diagram of the wireless sensor measuring device using FIG. 1, FIG.

Claims (4)

  A wireless transmitter slave with temperature and humidity sensors is placed on each of the items to be transported, and the temperature and humidity data are transmitted wirelessly. In the humidity sensor wireless collection system, the master unit accumulates the received data at any time in the internal recording device, and after the shipment arrives, just read the data of the recording device of the master unit, and the temperature and humidity history of the package being transported Temperature and humidity sensor wireless collection system, characterized by being able to grasp.   In the system of claim 1, a beacon transmitter is placed at the arrival location, and when the master unit receives this radio wave, the internal recording device data is transmitted to the arrival location receiver, and the history data is automatically transmitted via the network. A wireless collection system for temperature and humidity sensors, which can be transferred where necessary.   In the system according to claims 1 and 2, the master unit is always provided in a cold container or truck, and power is also supplied. When the power is turned off, reception recording can be continued with the internal battery, and the slave unit does not pass. A temperature / humidity sensor wireless collection system that is always installed in a box and does not require the trouble of mounting the main unit and the sub unit on the transported goods.   Regarding the temperature history management method for circulating goods that require temperature management, if a recording device is installed on each article, data recording costs and data transfer costs are incurred, and the article has only a sensor and wireless transmission means, and is transported. When data is collected wirelessly by the main unit, the data is aggregated in the main unit after arrival, so just reading the data of the main unit, the temperature and humidity history during the transportation of all the transported items in a short time A temperature and humidity sensor wireless collection system, characterized in that
