Embodiment Construction

[0011] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be pointed out that those skilled in the art can make some modifications and improvements without departing from the inventive concept, and these all belong to the protection scope of the present invention.

[0012] The principle of the BTM aging test process of the present invention is that the BTM host transmits a 27MHz signal to provide excitation energy for the BTM antenna, and the transponder reaches a normal working state through energy excitation, and the transponder sends 4.23MHz message information for the BTM host, while the BTM antenna Send the JC signal to the BTM host, and determine the working status of the BTM antenna and antenna cable according to the JC signal voltage.

Abstract

The invention discloses a BTM aging test system. The BTM aging test system comprises an A interface simulator, an upper computer, a serial port server and a BTM host computer under test, wherein the upper computer communicates with the BTM host computer through the serial port server; the A interface simulator is connected with the BTM host computer through a BTM antenna cable; the an A interfacesimulator comprises a radio frequency resistor, a RSG, a 27MHz filter board and a radiofrequency connector; the radio frequency resistor is taken as a load, substitutes for a BTM antenna, and is usedfor absorbing 27MHz radio frequency signal energy transmitted by the BTM host computer; a program of the RSG includes test messages, and is used for transmitting 4.23MHz message information to the BTMhost computer regularly; the radio frequency connector is connected with the BTM antenna cable, the radio frequency resistor and the 27MHz filter board, and transmits signals; the BTM aging test system can monitor the running states of a plurality of BTM host computers in real time to realize high-efficiency batch aging test; and at the same time, the system eliminates electromagnetic radiation and electromagnetic interference in an aging process.

Description

technical field [0001] The invention relates to a BTM aging test device, in particular to an aging test device without electromagnetic radiation. Background technique [0002] In the existing BTM aging mode, the BTM host is connected to the BTM antenna, and the manual shaking transponder sends message information for the BTM host. The 27MHz energy emitted by the BTM antenna is strong, and there is strong electromagnetic radiation in a certain space, which requires protection for personnel; at the same time, it will cause electromagnetic interference to close-range test equipment and affect each other with other tests; batch aging tests require multiple sets The BTM antenna takes up a lot of space. Contents of the invention [0003] The technical problems to be solved by the present invention are: 1. Eliminate electromagnetic radiation and electromagnetic interference during the operation of the aging test system; 2. Realize the real-time monitoring of the operating status...
