摘要： PROBLEM TO BE SOLVED: To solve the problem wherein sensor S around a leak place all start sending a warning to a base station by radio when hydrogen leak occurs in a hydrogen station in which a number of sensors are installed, and hence a line is saturated and the warning is not sent to the base station. SOLUTION: A node 100 is mutually, wirelessly connected to the base station 200 by an incoming line 301 and an outgoing line 300. The base station 200 detects congestion in the incoming line 301 by a radio RFMA 220, and notifies the node 100 of the congestion in the incoming line 301 by a means for sending to the outgoing line 300. Contrarily, the node 100 controls own transmission operation according to the level of the concentration of hydrogen detected by the hydrogen sensor 140 and the congestion of the line 301 notified from the base station 200, thus preventing the overflow of the line 301 where access is concentrated when hydrogen leaks, in advance.

摘要： PROBLEM TO BE SOLVED: To minimize power for heating an FET-type gas sensor employing a field effect transistor (FET), in order to prolong its operating lifetime longer.
SOLUTION: Two terminals 10, 11 are disposed on a sensitive electrode 31 deposited on a gate insulation film of the FET, and different potentials are applied them, thereby causing current to flow therein. Since the current flows in the sensitive electrode 31 itself having the need for heating, the sensitive electrode 31 becomes a heating element, whereby the FET-type gas sensor can be heated most efficiently. Furthermore, the terminals 10, 11 make up the portion of a temperature detecting section, thereby measuring the temperature of the heated sensitive electrode 31.

摘要： PROBLEM TO BE SOLVED: To reconcile low electric power consumption with wide concentration range measurement, as to a sensor device with an electric source built therein.
SOLUTION: The sensor device is made by combining an FET-system sensor of low electric power consumption having sensitivity in a low concentration zone and a sensor having sensitivity in a high concentration zone and requiring heater heating. An exemplary operation is shown below. Normally, in detecting gas leakage, the sensor for a low concentration zone is operated while interrupting the energization of a heater. When the FET-system sensor detects a value exceeding the first set threshold, the heater heating is started. If the temperature of the heater exceeds the second threshold, the start-up of the high concentration zone sensor is determined to have been completed. Thereafter, an output value of the FET-system sensor is used as an output value of the sensor device if concentration is equal to or less than the third set threshold while using an output value of the zone sensor as an output value of the sensor device if the concentration is equal to or more than the third set threshold.

摘要翻译：要解决的问题：为了使低功耗与宽浓度范围测量相一致，关于其中内置电源的传感器装置。
解决方案：传感器装置通过组合低浓度区域具有灵敏度的低功耗FET系统传感器和在高浓度区域具有灵敏度并需要加热器加热的传感器组成。示例性操作如下所示。通常，在检测到气体泄漏时，低密度区域的传感器在中断加热器的通电的同时被操作。当FET系统传感器检测到超过第一设定阈值的值时，开始加热器加热。如果加热器的温度超过第二阈值，则确定高浓度区域传感器的启动已经完成。此后，当使用区域传感器的输出值作为传感器装置的输出值时，如果浓度等于或小于第三设定阈值，则将FET系统传感器的输出值用作传感器装置的输出值如果浓度等于或大于第三设定阈值。版权所有（C）2007，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To restrain electric power consumption in a detection system using a gas sensor requiring heating for highly precise measurement. SOLUTION: This detection system is constituted of the plurality of gas sensors communicated with a server by radio communication, and each of the gas sensors is provided with a heater, a controller for controlling ON/OFF operations for electrification of the heater, and a comparator for comparing a detected gas concentration with a prescribed threshold value. The heaters in all the gas sensors are not electrified usually, the each gas sensor measures the gas concentration at low precision to be compared all the time with the threshold value. When the gas concentration exceeds the threshold value in the one gas sensor, the own heater is turned on to be switched to high precision of measurement, and the heater is turned off after finishing the measurement. Detection of exceeding the threshold value is reported to the server at the same time, and the server lowers the threshold value of the gas sensor in the periphery of the gas sensor notified with the detection of exceeding the threshold value so as to make a monitoring level severe.
