地磅测试程序,将字符串发送到指定COM口,基于VB写的地磅仪表数据读取工具源码,包括调用了一个仪表通信采集工具、上海耀华、托利多等大众仪表,有一定的参考价值。
设置Com1为通信端口,设置通信端口参数 9600赫兹、偶校验、7个数据位、1个停止位.(这里需要进一步说明的是tting="BBBB,P,D,S,含义是:B:Baud Rate(波特率);P:Parity(奇偶);D:Data Bit;S:Stop Bit)。
.InBufferSize = 40 设置缓冲区接收数据为40字节
.InputLen = 1 设置Input一次从接收缓冲读取字节数为1
.RThreshold = 1 设置接收一个字节就产生OnComm事件。
Timer可以计算从子夜到现在所经过的秒数,在Microsoft Windows中,Timer函数可以返回一秒的小数部分。(Weighbridge test program, the string will be sent to the specified COM port, source-based reading tool written in VB weighbridge instrumentation data, including calling an instrument of communication collection tools, Shanghai Yaohua, Toledo and other public instruments, there is a certain reference value.
Set Com1 communications port, set the communications port parameters 9600 Hz, even parity, 7 data bits, 1 stop bit (It should be further noted that tting = "BBBB, P, D, S, meaning:. B: baud Rate (baud rate) P: Parity (parity) D: Data Bit S: Stop Bit).
. InBufferSize = 40 is set to receive data buffer is 40 bytes
. InputLen = number Set Input once read from the receive buffer byte 1 of 1
. RThreshold = 1 is set to receive a byte generated OnComm event.
Timer can be calculated from midnight to now the number of seconds elapsed, in Microsoft Windows, Timer function can return a decimal fraction of a second.)
