摘要： In a hydrogen gas station where a great number of sensors are installed, in case hydrogen leakage occurs, sensors in the vicinity of the leakage location start to transmit a warning to an access point all at once. This causes channel capacity saturation and failure to transmit a warning to the access point. Nodes and the access point are connected to each other by an uplink channel and a downlink channel. The access point detects congested/uncongested status of the uplink channel by using a wireless transmitter module and notifies the nodes of the congested/uncongested status of the channel by means for transmitting onto the downlink channel. Meanwhile, each node controls its transmission operation, according to the hydrogen concentration level detected by its hydrogen sensor and the uplink channel congested/uncongested status notified from the access point. In this way, channel overflow due to access congestion in case of hydrogen leakage can be prevented.
摘要翻译：在安装有大量传感器的氢气站中，在发生氢泄漏的情况下，泄漏位置附近的传感器开始向接入点一次性发送警告。这会导致通道容量饱和，并且无法向接入点发送警告。节点和接入点通过上行链路信道和下行链路信道相互连接。接入点通过使用无线发射机模块来检测上行链路信道的拥塞/非占用状态，并通过传输到下行链路信道的方式向节点通知信道的拥塞/非占用状态。同时，每个节点根据其氢传感器检测到的氢浓度水平和从接入点通知的上行链路信道拥塞/非占用状态来控制其传输操作。以这种方式，可以防止在泄漏的情况下由于访问拥塞而导致的信道溢出。

摘要： It is an object of the present invention to minimize the power for heating of an FET-type gas sensor using an FET to ensure a long operating life.Two terminals 10 and 11 are arranged at a sensitive electrode 31 formed on a gate insulation film of an FET, and different potentials are applied thereto to cause a current to flow. The sensitive electrode 31 functions as a heating element by causing a current to flow in the sensitive electrode 31 which needs to be heated, allowing the FET-type gas sensor to be heated most efficiently. Furthermore, the terminals 10 and 11 configure a part of a temperature detector which measures the temperature of the heated sensitive electrode 31.

摘要： A gas detection system capable of suppressing the power consumption of the system using gas sensors required for heating for measurement at high accuracy, comprising a server and a plurality of gas sensors connected by way of wireless communication with the server, in which each of the gas sensors is provided with a heater, a controller for controlling the ON-OFF for the power supply to the heater and a comparator for comparing the detected gas concentration with a predetermined threshold value. In the gas detection system, electric power is not usually supplied to the heater in each of the gas sensors and the gas sensor measures the gas concentration at a low accuracy and always compares it with the threshold value. In a case where the gas concentration exceeds the threshold value in one of the gas sensors, it turns the heater of its own to ON thereby switching the measurement to that at high accuracy and turns the heater to OFF upon completing the measurement. At the same time, it informs the detection for the excess of threshold value to the server and the server lowers the threshold value of the gas sensors in the vicinity of the gas sensor that has informed the detection for the excess of threshold value to make the monitoring level severer.
摘要翻译：一种气体检测系统，其能够以高精度抑制用于加热测量所需的气体传感器的系统的功率消耗，包括通过与服务器的无线通信连接的服务器和多个气体传感器，其中每个气体传感器设置有加热器，用于控制对加热器的电源的ON-OFF的控制器和用于将检测到的气体浓度与预定阈值进行比较的比较器。在气体检测系统中，通常不向每个气体传感器中的加热器供电，气体传感器以低精度测量气体浓度，并且始终将其与阈值进行比较。在其中一个气体传感器中气体浓度超过阈值的情况下，它将其自身的加热器变为ON，从而将测量值以高精度切换，并在完成测量时将加热器转为OFF。同时，它通知检测到服务器的阈值过大，服务器和服务器降低气体传感器附近的气体传感器的阈值，该气体传感器通知检测阈值超过阈值，监控级别更严重。
