Description

Electronic detonator leg wire multi-type switching system and equipment based on relay parallel connection Technical Field The invention belongs to the technical field of detonator wire testing, and particularly relates to a relay parallel connection-based electronic detonator leg wire multi-type switching system and equipment. Background In the current electronic detonator industry, the application environment of the electronic detonator in the field use process is very complex, and the requirements on the stability of the electronic detonator communication are very strict. The electronic detonator has different communication performances when the terminal loads are different in an application environment. In the prior art, the characteristics of the electronic detonator terminal load influencing the communication performance have two key dimensions, namely a first key dimension, a communication wire (material and length) between a load terminal and an electronic detonator controller, a second dimension and terminal electronic detonator configuration conditions (electronic detonator leg wire length and electronic detonator quantity). The communication line materials used on site have various characteristics, and the connection length is from tens of meters to one kilometer. The load quantity of the electronic detonator in different application occasions is from several hundred, and the length of the leg wire used by the electronic detonator also has a plurality of length specifications. In long-time use observation, the use configuration of the electronic detonator at the field terminal is very complex, and if the full coverage test of each application terminal cannot be performed, the communication stability of the electronic detonator is potentially risky, and the communication stability of the electronic detonator at the field application cannot be ensured. However, because of the diversity of applications of the communication terminal, if a test environment is made by a physical equivalent method, the execution process is limited by a site, and a large amount of test time are required, so that the test efficiency is low, the purpose of testing cannot be achieved rapidly, and the product development progress of the electronic detonator communication system is seriously affected. In order to test the communication stability of different terminal configurations in the current electronic detonator industry, various terminal configurations are usually simulated by adopting an equivalent load, and the specific practice of the equivalent load is that a communication medium (a communication wire, a wire length, a foot line length and the like) uses a method of connecting an equivalent resistor in series and an equivalent capacitor in parallel to simulate the equivalent load, but the simulated load and the load actually used by the test are very different in test result, and have a great misleading effect on the authenticity of the test result. In combination with the industry requirement of the rapid development of the electronic detonator, the development of the electronic detonator needs a test system to be close to the application of a real application environment, and has higher requirements on test coverage, high test efficiency, occupied area and the like. Therefore, the invention provides a relay parallel-based electronic detonator leg wire multi-type switching system and equipment.
