Industrial wireless sensor system

A factory automation system, comprising:

• an industrial wireless sensor system (100) comprising:
• a wireless magnetic field sensor (110) attached to a pneumatic cylinder (118) to grasp a position of the pneumatic cylinder;
• a wireless limit sensor (210) installed on a bottom of a rail to detect a jig bogie that is seated on the rail and moves to each process in an automated production line;
• and
• a wireless proximity sensor (310) attached to a side surface of a clamp supporting a panel and determines whether the panel in on the jig bogie;
• a factory controller (400) having a wireless communication unit (410) wirelessly connected to the industrial wireless sensor system (100) to provide radio resources for downlink command transmission and uplink response, and configured to periodically transmit commands to the industrial wireless sensor system (100) such that the industrial wireless sensor system (100) returns a sensing information response or an acknowledgment response per cycle time of 2 ms to 20 ms;
• a monitoring controller (430);
• a network security unit (440);
• and
• a network management unit (450),
• wherein the industrial wireless sensor system (100) is configured to detect an analog signal and convert the analog signal into a digital signal,
• wherein the wireless communication unit (410) is configured to receive the digital signal from the industrial wireless sensor system (100) and convert the digital signal into a wireless signal, and transmit the wireless signal to the factory controller (400),
• wherein the factory controller (400) is configured to transmit a sensor failure signal to a factory network (420) if a response signal received by the factory controller from the industrial wireless sensor system (100) is not matched to a command transmitted to the industrial wireless sensor system (100) or if no response signal is received,
• wherein the monitoring control unit (430), the network security unit (440), and the network management unit (450) are respectively connected to the factory network (420) to enable to manage the industrial wireless sensor system (100) to identify which one of the wireless magnetic field sensor (110), the wireless limit sensor (210), the wireless proximity sensor (310) is failed.
