Description

technical field [0001] The invention relates to the technical field of seismic exploration, in particular to a wireless trigger device. Background technique [0002] At present, the known shallow hammer wired trigger is made up of a trigger switch, a weight, a spring, and a sleeve. Combine the trigger switch with the spring, weight and sleeve, and connect them together through cables to do wired synchronous triggering. Due to the many mountains and high roads in the field, the effective communication between the vibrator vehicle and the instrument vehicle is a problem. Therefore, the distance of the communication process is greatly restricted, and the complex terrain is greatly restricted, which makes the instruments and equipment constantly moved and transported, causing a lot of inconvenience. [0003] In order to overcome the shortcomings of the existing wired triggering devices, it is necessary to develop a wireless triggering device that is not limited by distance, but...
