Embodiment

[0020] Such as figure 1 Shown, a kind of chip program repairing method of telephone program-controlled exchange, comprises the following steps:

[0021] Step S1: The diagnosis module judges whether the program in the chip of the telephone program-controlled exchange is damaged, if not, execute step S1 again; if yes, execute step S2.

[0022] Step S2: The computer invokes the corresponding preset program according to the chip type.

[0023] Step S3: The computer sends the preset program to the burning module.

[0024] Step S4: The burning module burns the preset program into the chip.

[0025] Wherein step S1 specifically comprises the following steps: first the diagnostic module reads the corresponding preset program in the computer according to the chip type, then reads the program in the chip of the telephone program-controlled switch, and the diagnostic module judges whether the program in the chip of the telephone program-controlled switch is consistent with the preset p...

Abstract

The invention relates to a chip program repair method of a telephone stored program control exchange. The chip program repair method comprises the following steps that: 1) a diagnosis module judges a program in the chip of the telephone stored program control exchange is damaged or not, if not, the step 1 is executed again, and if so, a step 2 is executed; 2) a computer calls a corresponding preset program according to the type of the chip; 3) the computer transmits the preset program to a burning module; and 4) the burning module burns the preset program into the chip. Compared with the prior art, the chip program repair method of the telephone stored program control exchange has the advantages that the damaged program in the chip is only required to be reset, the repair rate is high, the replacement of hardware is not needed and the maintenance cost is low.

Description

technical field [0001] The invention relates to a maintenance method for a communication system, in particular to a method for repairing a chip program of a telephone program-controlled exchange. Background technique [0002] With the development of computer technology and the continuous development of assembly language applications, the control system in the equipment basically adopts program control. On the hardware, a control execution system is composed of three chips. A large-scale integrated chip integrates all the functions to be executed. A readable and writable EPROM memory stores the execution function commands in it. When the power is turned off, it will not be lost. A random access memory is used in the working state. [0003] Due to problems in circuit design and user problems, the program software stored in the readable and writable EPROM memory is modified, making the device unusable. The proportion of such phenomena in repairs is increasing day by day. Cont...
