Patent number: 9108823Abstract: 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.Type: GrantFiled: March 12, 2010Date of Patent: August 18, 2015Assignee: Mitsubishi Electric CorporationInventors: Kazunori Washio, Masafumi Iwata, Takuya Ishioka

Patent number: 8959405Abstract: 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.Type: GrantFiled: February 8, 2010Date of Patent: February 17, 2015Assignee: Mitsubishi Electric CorporationInventors: Masahiko Ikawa, Kazunori Washio, Masashi Kitayama, Takuya Ishioka, Hiroyuki Kumazawa
