Abstract
The utility model relates to a circuit structure of a quality monitoring system during electric resistance welding, which is characterized in that a spot welding monitoring structure is in master-slave mode, a computer is adopted as an upper computer, and a singlechip is adopted as a lower computer; the CPU1 (Central Processing Unit) of the computer conducts data transmission with a RAM (random access memory), and the CPU2 of the singlechip reads the data from the double-interface RAM and transmits the data to a personal computer. The circuit structure can ensure that the quality monitoring data during spot monitoring is accurate, the operation is normal and the signal is not interrupted.
Description
Technical field
The utility model relates to a kind of circuit structure of electric resistance welding procedure quality monitoring system, is applied to the resistance spot welding process quality monitoring function.
Background technology
Pinpoint welding procedure is the complex process that factors such as a heat, electricity, power, metallurgy intercouple; As everyone knows; There is certain relation between the parameter in welding quality and the welding process,, at first should as much as possiblely detects those parameters relevant with point quality in order better to control welding quality; Next is the relation that finds these parameters and point quality, promptly extracts characteristics of objects information.The relation of single parameter and point quality can be represented through a certain characteristic information of analyzing and test obtains; And the relation of multi-parameter and quality promptly is the set of these characteristic informations; Can the exploit information fusion method carry out the high accuracy fusion, finally obtain effective description of point quality multi-sensor data.
Summary of the invention
The purpose of the utility model is to provide a kind of circuit structure of electric resistance welding procedure quality monitoring system, and its data that can guarantee pinpoint welding procedure quality monitoring accurately, normal, the signal of operation do not disturbed.
The technical scheme of the utility model is achieved in that the circuit structure of electric resistance welding procedure quality monitoring system, it is characterized in that: the spot welding monitoring structure is a master-slave mode, and host computer adopts computer, and slave computer adopts single-chip microcomputer; The CPU1 of computer and dual port RAM data transmit, and the CPU2 of single-chip microcomputer reads data and sends to personal computer from dual port RAM.
The good effect of the utility model be can guarantee pinpoint welding procedure quality monitoring data accurately, normal, the signal of operation do not disturbed.
Description of drawings
Fig. 1 is the structure principle chart that the circuit of the utility model connects.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further: as shown in Figure 1, the circuit structure of electric resistance welding procedure quality monitoring system is characterized in that: the spot welding monitoring structure is a master-slave mode, and host computer adopts computer, and slave computer adopts single-chip microcomputer; The CPU1 of computer and dual port RAM data transmit, and the CPU2 of single-chip microcomputer reads data and sends to personal computer from dual port RAM.
Resistance spot welding monitoring system hardware mainly consists of the following components: two 80C51F020 chips; Dual-port storage chip IDT71V32, ethernet controller CS8900A, address latch 74HC573; Network interface HR901175A, and other control circuit constitutes.In this resistance spot welding process Quality Monitoring Control System; The 80C51F020 chip of selecting two compatible MCS-51 kernels is as key control unit; CPU1 mainly is responsible for the pinpoint welding procedure parameter is gathered and the resistance spot welding control information that utilizes CPU2 to transmit is controlled pinpoint welding procedure.CPU2 mainly is the work load that alleviates CPU1, is responsible for the communication of Ethernet.Both carry out the data interchange through dual-port storage chip IDT71V32 and share.Ethernet controller LAN process chip CS8900A; Utilize 8 interface modes of CS8900A; The CPU2 that is responsible for communication is connected with CS8900A; The form of ethernet controller Ethernet data bag sends to the pinpoint welding procedure parameter host computer and gives CPU2 with the control information data packet delivery that computer sends through network interface.
