Abstract: An electromagnetic valve manifold includes valve assemblies arranged in a single direction, each valve assembly including electromagnetic valves arranged in the single direction, a slave station disposed at one of ends of the electromagnetic valve manifold in the single direction, and a valve driving unit disposed in correspondence with each of the valve assemblies. The slave station includes a slave station output port that sends a control signal and valve driving unit power to the valve driving units. The valve driving units each include an electromagnetic valve power input port that receives electromagnetic valve power from an external device and a circuit board configured to control driving of the electromagnetic valves of a corresponding one of the valve assemblies using the control signal and send the electromagnetic valve power to the electromagnetic valves.

Abstract: A space monitoring system includes environment measuring means for measuring an atmospheric environment of a monitored space (S), person sensing means for sensing the existence of a person in the monitored space (S), space condition calculating means for calculating whether the monitored space is an indoor environment likely to cause droplet infection or whether the monitored space is expected to become an indoor environment likely to cause droplet infection, based on atmospheric environment data measured by the environment measuring means and person data sensed by the person sensing means, and display means for displaying an indication for facilitating a user to improve an existing indoor environment likely to cause droplet infection or prevent the monitored space from becoming an indoor environment likely to cause droplet infection, based on a result of calculation by the space condition calculating means.
