て設定してきた。Conventionally, a plurality of abnormality detectors are all installed within a predetermined security area, and the abnormality information from these detectors is converted into 4Q signals and reported to a specific monitoring bag #ttF: by wired or wireless means. In addition, a security system has already been proposed in which a monitoring signal is sent from a Zara-Ni-Kanko device to monitor the presence or absence of an abnormality in an installed anomaly detector. The configuration of such a security system consists of a group of anomaly detectors installed at appropriate locations within a security area such as inside a building, and a transmitter/receiver that is attached to the anomaly detector and transmits anomaly information or receives all monitoring signals. 1, and a monitoring device installed at a predetermined location within the IiJ area in order to receive abnormality information from the transmitting/receiving device and report it to the monitoring station, or to transmit a monitoring signal from the monitoring station. In such a security system, the method of collecting security information such as security start, security release, or abnormality is to turn on the power of the transmitting/receiving device for a certain period of time using a standby signal, and then check the reception ready state (the state in which the device is ready to receive data). ), the number of relay devices connected to the monitoring device and the number of transmitting/receiving devices connected to each relay device are set in advance, and the time for transmitting and receiving information between one transmitting/receiving device and the relay device is set in advance. After setting, the required transmission/reception time (polling time) between all transmitting/receiving devices and all relay devices is calculated, and the reception ready time is set to a time slightly longer than this total transmitting/receiving time.

の欠落金防いできた。By setting the time in this way, we have prevented the loss of security information collection, but on the other hand, due to extensions, renovations, and changes in the layout of buildings within the security area, the number of anomaly detectors has increased, or the number of transmitting and receiving devices has increased due to movement. If this occurs, of course,
The total transmission/reception time increases by the amount of additional equipment, and exceeds the reception ready time. However, the reception 1δ ready time cannot be set arbitrarily long to save battery power, and therefore a new monitoring device f: By adding more units, we have been able to prevent loss of security information.

することにある。However, with this type of system, it is necessary to consider the addition of monitoring equipment every time the building is frequently extended or renovated or the layout is changed, which causes problems such as the rise of the court and lack of flexibility. Furthermore, from the beginning of the design, a method was considered in which the number of transmitting/receiving devices and the number of relay devices were set to have a longer reception ready time. Even when the amount of electricity is low, streetcars are being consumed unnecessarily, which poses a problem from the viewpoint of battery conservation.The present invention is proposed to solve the above-mentioned problems, and its purpose is to: Always compare the time required between the transmitting/receiving device and the relay device and the reception ready time, and if there is no margin in the reception ready time, send a request to all monitoring devices to reset the reception resolution to 1 hour. Based on the idea of providing a function to a relay device, this security system is effective in preventing the loss of security information and saving battery power without the need to install additional monitoring devices due to building extensions, renovations, layout changes, etc. (The aim is to provide a method for collecting security information at /koo.
