Embodiment Construction

[0015] Referring to Fig. 1, it is a hardware architecture diagram of a preferred embodiment of the button life testing system of the present invention. The preferred embodiment is described by taking a telephone as an example. The system includes a key input module 1, a single-chip microcomputer 2, a liquid crystal display module 3, an air pressure regulator 4, a plurality of solenoid valves 5 (only one is shown in the figure), a plurality of direct-acting cylinders 6 (only one is shown in the figure). out one) and one telephone7.

[0016] Among them, the key input module 1 provides three multi-function buttons, which are used to receive instructions for opening and closing the test system, and receive parameters that need to be set for testing. And the time interval between two key actions, etc. The key input module 1 can also transmit the received setting parameters to the single-chip microcomputer 2 connected to it in the form of digital signals.

[0017] The single-chip...

Abstract

The invention provides a testing system for the keystroke life including a keystroke input module, a singlechip, a liquid crystal display module, an air pressure regulator, at least one electromagnetic valve and at least one direct-acting air cylinder. The keystroke input module is to incept the order of the starting and closing testing system and incept the testing parameter. The singlechip includes a microprocessor and an application; the microprocessor can order the electromagnetic valve by carrying out the application. The liquid display module is to display the setting testing times and the present testing times. The air pressure regulator supplies the air pressure for the direct-acting air cylinder to make it move up and down by the electromagnetic valve to control the button and test the button life. The invention also provides a method. The invention constructs by the singlechip instead of the PC, so it has the function of speed adjustment and the power-off protection function.

Description

【Technical field】 [0001] The invention relates to a key testing system and method, in particular to a key life testing system and method. 【Background technique】 [0002] In order to ensure the quality of the telephone before leaving the factory, the performance of each component must be strictly tested. The test mainly includes: testing the ringing of the telephone, testing the pulse or dual-tone dialing circuit and the call circuit (including sending and receiving calls) Whether it is normal, and the test of the telephone button, etc. Previous button life test systems generally use a computer (Personal Computer, PC) architecture, which is not flexible enough to apply, and most test systems lack the test speed adjustment function and power-off protection function, so the measurement results may be damaged when the power is off. Accidentally lost. 【Content of invention】 [0003] In view of the above, it is necessary to provide a key life testing system, which uses a singl...
