Example Embodiment

[0028] Example 1:

[0029] 1. The overall structure of the interface circuit

[0030] The interface circuit is a key component of the device to meet the design requirements, and its function and reliability directly affect the performance of the entire system. figure 1 It is the overall block diagram of this device.

[0031] by figure 1 It can be seen that the interface circuit includes: switch input and output circuit, potentiometer test circuit, indicator test circuit, digital logic input and output circuit, switching and switching control circuit, connector access automatic detection circuit, bus interface circuit (CPLD1, CPLD2, CPLD3, CPLD4), analog-to-digital conversion circuit (ADC) and other parts.

[0032] Among them, the switch input and output circuit is used for the short-circuit and open-circuit scanning test between the console pin and the power supply +, the power supply common terminal and the pin; at the same time, it is also used for the state test of the intern...

Abstract

The invention discloses an online operating console detection device. The device is characterized by comprises an operating console, an interface circuit and a control circuit. An outgoing line of the operating console is connected with the interface circuit, and the control circuit is connected with the interface circuit; the interface circuit comprises a signal switching branch circuit, one end of the signal switching branch circuit is connected with a switching control signal of the control circuit, and the other end of the signal switching branch circuit is connected with the outgoing line of the operating console, and the interface circuit further comprises a relay, a control terminal of the relay is connected with the switching control signal, and an output terminal of the relay controls a path of the outgoing lines of the operating console to be connected with two current branch circuits, namely a current L1 branch circuit and a current L2 branch circuit. The online operating console detection device can be adaptive to a plurality of operating consoles, has good extension performance, good compatibility and high reliability.

Description

technical field [0001] The invention belongs to the field of electronic technology and relates to an online detection device for a console. Background technique [0002] For console control, the traditional technical method is to design a set of specific circuits for a specific console. For example, the number of lead-out lines of different consoles is the same, and among the lead-out lines of different types of consoles, many lead-out lines represent different signals. Therefore, according to the traditional design method, it is necessary to design different interface circuits for different types of consoles. Therefore, the compatibility of the existing console detection devices is extremely poor, and the expansion function is also poor, and it also causes extreme manpower and material resources. Big waste. Contents of the invention [0003] The technical problem to be solved by the present invention is to propose an online console detection device for the disadvantages...
