The automatic testing device of the communication network controller mainly comprises a testing control module, a parameter configuration module, a signal acquisition card, an analog voice circuit exchange card, a data transmission radio station analog module and a voice terminal analog module. The test control module, the parameter configuration module, the signal acquisition card, the data transmission radio station simulation module and the voice terminal simulation module are arranged in an industrial control computer and are uniformly controlled by the test control module arranged in the industrial control computer. The parameter configuration module is mainly used for configuring parameters of the communication network controller, the signal acquisition card is mainly used for acquiring interface signals from the communication network controller, and the analog voice circuit switch card is mainly used for communicating any two analog voice circuit interfaces of the network controller. The data transmission radio station simulation module and the voice terminal simulation module simulate a radio station and a voice terminal and are connected with all radio stations and voice terminal interfaces of the communication network controller through special cables. The test control module generates corresponding configuration information and control instructions according to various test cases, and realizes automatic test of functions of each interface of the communication network controller through various board cards, so that the test efficiency is improved, and the test cost is reduced.
