Embodiment approach 1
[0021] use figure 1 The configuration of the remote monitoring system according to Embodiment 1 of the present invention will be described. This system is a remote monitoring system in which a monitoring center monitors elevators installed in a remote building 1 .
[0022] exist figure 1 In the building 1, three elevators (not shown) are provided. The three elevators each have a car (not shown) for passengers to get on and off and an elevator control panel (control device) for controlling the movement of the car. figure 1 In , the elevator control panels corresponding to the three elevators are represented as elevator control panels 2a, 2b, and 2c. The elevator control panels 2a, 2b, and 2c are installed inside a machine room (not shown) or a hoistway (not shown) of an elevator. The elevator control panels 2a, 2b, 2c send status signals indicating the status of the elevator. There are situations where the status signal includes communication requests that allow a long wait...
Embodiment approach 2
[0056] In Embodiment 1, the total of the allowable waiting time excess values OTb, OTc is obtained as an evaluation value. However, when the evaluation value is a simple sum of the allowable waiting time excess values OTb and OTc, there are cases where the evaluation value of the allowable waiting time exceeding value of a small value is larger than a large value in a state where many communication request signals are scattered. When the allowable waiting time excess value is concentrated in the evaluation value in the state of a small number of communication request signals. In this case, depending on the communication request signal, there is a possibility that the allowable waiting time may be greatly exceeded. It may become an undesirable situation for high-urgency communication requests.
[0057] Therefore, in Embodiment 2, it is assumed that the evaluation value is obtained using an evaluation function, not a simple sum of allowable waiting time excess values. In t...
Embodiment approach 3
[0062] exist figure 1 In , when the communication request signal to the access point 6a is generated more frequently than the communication request signal to the access point 6b, it can be considered that by switching from the access point 6a to the access point 6b, the communication request signal to be generated in the future will be reduced The communication wait time of the communication request signal increases. Therefore, by considering the frequency of use of the communication path, that is, the frequency of occurrence of each communication destination of the communication request signal in the past when calculating the evaluation value, it is possible to select a communication path that also takes into account the communication request signal that will be generated in the future. .
[0063] For example, the evaluation value when the modem 5 is connected to the access point 6a is calculated using the following formula. Equation 7 is an expression for calculating an ev...
