The debugging is completed, and the debugging results are recorded in the storage module; 步骤S2中,调试终端首次与电力系统网络设备进行连接时,通过嵌入式CPU中的发送模块发送网络请求信息,所述网络请求信息包括调试终端的设备地址信息,同时嵌入式CPU中的计时器开始计时,所述电力系统网路设备端口接收到调试终端的网络请求信息,对网络请求信息进行解码,解码成功后,将电力系统网络设备的设备地址信息、网络验证信息以及网路请求信息打包为网络反馈信息发送至调试终端,嵌入式CPU中的接收模块接收网络反馈信息后进行解码,同时嵌入式CPU中计时器停止计时,调试终端对网络设备信息进行解码,验证信息的完整性,若网络出现异常,则在触摸屏上报警提示,同时调试终端将电力系统网络设备的设备地址信息、计时器的时间段信息以及调试终端的设备地址信息打包为原始信息存储在存储模块中,并对原始信息进行编号,便于下一次手动调试模式使用;In step S2, when the debugging terminal is connected with the power system network device for the first time, the network request information is sent through the sending module in the embedded CPU, and the network request information includes the device address information of the debugging terminal, while the timer in the embedded CPU is used. Start timing, the power system network device port receives the network request information from the debugging terminal, decodes the network request information, and after successful decoding, packs the device address information, network verification information and network request information of the power system network device In order to send the network feedback information to the debugging terminal, the receiving module in the embedded CPU decodes the network feedback information after receiving the network feedback information. At the same time, the timer in the embedded CPU stops timing. The debugging terminal decodes the network device information and verifies the integrity of the information. If the network is abnormal, an alarm will be displayed on the touch screen. At the same time, the debugging terminal will package the device address information of the power system network equipment, the time period information of the timer and the device address information of the debugging terminal into the original information and store it in the storage module. The information is numbered, which is convenient for the next manual debugging mode; 在原始信息已经存储在存储模块中的情况下,选用自动调试模式对电力系统网络设备进行调试时,在发送模块发送网络请求信息之前,需要采用侦听信道的防碰撞机制,确定当前信道的空闲时段,通过发送模块中的发送机在信道空闲时段发送完整的网络请求信号数据;发送机根据原始信息编号产生随机等待一段时间再发送下一段网络设备请求信号;如果发送前侦测到信道繁忙,根据发射机噪声产生随机数,等待延时此随机数时间后再发送,直至自动化调试完所有电力系统网络设备。When the original information has been stored in the storage module, when the automatic debugging mode is selected to debug the power system network equipment, before the sending module sends the network request information, the anti-collision mechanism of the listening channel needs to be used to determine the idleness of the current channel. During the period, the transmitter in the sending module sends the complete network request signal data during the idle period of the channel; the transmitter randomly waits for a period of time to send the next network device request signal according to the original information number; if the channel is detected busy before sending, Generate random numbers according to the transmitter noise, wait for the delay of the random number time before sending, until all power system network devices are automatically debugged. 2.根据权利要求1所述的一种电力系统自动化网络专用调试终端,其特征在于:2. a kind of power system automation network special debugging terminal according to claim 1 is characterized in that: 所述触摸屏驱动电路包括背光驱动电路和白光驱动电路,所述背光驱动电路包括有驱动芯片U2,驱动芯片U2的第一引脚通过电感L1与电源电连接,驱动芯片U2的第五引脚与第四引脚连通后通过电容C13接地,驱动芯片U2的第二引脚接地,所述驱动芯片U2的第1引脚与稳压二极管D2的阳极端电连接,稳压二极管D2的阴极端与电阻R8的第一端电连接,电阻R8的第二端与驱动芯片U2的第三引脚电连接,驱动芯片U2的第三引脚与电阻R9的第一端电连接,电阻R9的第二端与电阻R10 的第一端电连接,电阻R10的第二端接地,电阻R8的第一端与电容C14的第一端电连接,电容C14的第二端电连接,电容C14的第一端与二极管D5的阳极端电连接,二极管D5的阴极端与二极管D3的阳极端电连接,二极管D3的阳极端与电容C15d第一端电连接,电容C15的第二端与稳压二极管D2的阳极端电连接,二极管D3的阴极端与电阻R11的第一端电连接,电阻R11的第二端与与电阻R12的第一端电连接,电阻R12的第二端与电阻R13的第一端电连接,电阻R13的第二端接地,电阻R12的第一端与电容C16的第一端电连接,电容C16的第二端与电阻R13的第二端电连接,电容C16的第一端作为触摸屏的VGH端;电容C15的第二端与电容C17的第一端电连接,电容C17的第二端与二极管D6的阴极端电连接,二极管D6的阳极端与电阻R15的第一端电连接,电阻R15的第二端与电阻R16的第一端电连接,电阻R16的第二端与二极管D4的阴极端电连接,二极管D4的阳极端与二极管D6的阴极端电连接,电阻R16的第一端与电容C18的第一端电连接,电容C18的第二端接地,电容C18的第一端作为触摸屏的VGL端。The touch screen drive circuit includes a backlight drive circuit and a white light drive circuit.
