摘要:
An elevator safety control device realizing suppression in increase in cost and labor hour of installation and maintenance without deteriorating safety of normal safety control functions even when a plurality of safety control functions are provided. The elevator safety control device includes an independence assurance unit assuring independence of a safety control function. The independence assurance unit assures independence of each of the safety control functions by monitoring whether or not the safety control function accesses a memory other than a permitted region. When the independence assurance unit detects an access to the memory other than the permitted region by a predetermined safety control function, the elevator safety control device stops a car.

In an elevator control apparatus, the presence/absence of an abnormality in an elevator is monitored by an abnormality monitoring portion. The abnormality monitoring portion makes a determination on the presence/absence of an abnormality in the elevator based on information from a sensor, and outputs a signal for stopping a car upon detecting an abnormality. The history of information on the result of determination by the abnormality monitoring portion is recorded in a history information recording portion.

Each of a control panel node 2 and an input/output node 3 has a safety data processing unit 7 and a high reliability communication unit 8. At the time of transmission, the safety data processing unit 7 creates a safety data packet including data about safety and the high reliability communication unit 8 creates a communication data packet including the safety data packet from the safety data processing unit 7 and transmits the communication data packet a predetermined number of times. At the time of reception, the high reliability communication unit 8 acquires and outputs a safety data packet by determining one of one or more communication data packets having the same contents which it has received properly as an effective packet, and the safety data processing unit 7 analyzes a state concerning the safety of a system on the basis of the data about safety acquired from the safety data packet from the high reliability communication unit 8.

Each of a master node and a slave node has a safety data processing unit and a high reliability communication unit. At the time of transmission, the safety data processing unit creates a safety data packet including data about safety and the high reliability communication unit creates a communication data packet including the safety data packet and transmits the communication data packet a predetermined number of times. At the time of reception, the high reliability communication unit acquires and outputs a safety data packet by determining one of one or more communication data packets having the same contents which it has received properly as an effective packet, and the safety data processing unit analyzes a state concerning the safety of a system on the basis of the data about safety acquired from the safety data packet.

An information processing apparatus includes a network structure generation unit that generates a network structure showing relations formed between registered users at a predetermined time based on user information containing attribute information showing attributes of the registered user registered with a social networking service (SNS) and registration time information showing a registration time of the registered user, and relation information containing relation formation information showing a relation formed between the registered users on the SNS, and relation formation time information showing a relation formation time, a network image generation unit that generates a network image representing the generated network structure with the registered user as a node and a relation formed between the registered users as an edge, and a network image display unit that chronologically displays the generated network images at a plurality of the predetermined times. Accordingly, a change of SNS operation conditions can efficiently be grasped.
