The present invention provides an alarm information transmission method, a sensor node device and a gateway node device so as to solve the problem in the prior art that alarm information generated by a sensor node cannot be transmitted in time. Unlike conventional ESD protection circuit using high turn-on voltage diode string, the circuit uses a plural of enhancement-mode HEMTMESFET triggered by a shorter diode string to shunt large ESD current for protected susceptive RF circuit. The grips are open on opposite sides, and are spaced apart to allow the bracket to pass over a support column such as an upright for a guardrail on a personnel lift. A determination is made of application specific information for the generated business object indicating a correspondence of the fields in the business object to the application specific data structure.
