The alarm module 400 sends alarm information in response to the alarm signal and performs an alarm operation.
Specifically, the enterprise management control system is an ABB Symphony system, and the ABB Symphony system is composed of a set of modules which use a microprocessor to execute control functions. The selection and the mutual cooperation of the control functions are realized on the main module through the composite software configuration 'function block'. A functional block is simply an input or output or an operation of an input or output. These function blocks are generic software control algorithms that can be used to perform specific tasks that require specialized hardware to perform in other types of systems, such as status displays, operations, parameters, alarms, etc. of the device. It has four types of functional blocks: an execution block containing parameters that affect the integrated operation of the modules; system constant blocks, to which some digital quantity parameters and analog quantity parameters such as 0, 1 and 100, 0, etc. belong; an input/output block which is a fixed block address and is a field input and output corresponding to each module through a terminal unit and field wiring; a user configuration block. The user configuration block is not a pre-designated block but is set by the user to perform user-specific functions to implement the control logic.

The apparatus of claim 2, wherein the logical operation circuit comprises a fourth AND gate, a fifth AND gate, a fourth OR gate, a fifth NOT gate, and a sixth NOT gate; the at least one protection interlocking switching module is connected with the input end of the fourth AND gate; at least one of the operating condition detecting modules is connected to an input of the fourth or gate, an output of the fourth or gate being connected to an input of the fifth not gate; the output end of the fourth and gate and the output end of the fifth not gate are respectively connected with the input end of a fifth and gate, the output end of the fifth and gate is connected with the input end of a sixth not gate, the output end of the sixth not gate is connected with the exception report measuring point module, and the sixth not gate is used for outputting the level operation result to the exception report measuring point module.
6. The device of claim 1, wherein the alarm operation comprises an audible alarm and/or a flashing alarm.
7. The apparatus according to claim 1, wherein the alarm module pushes the alarm information to a display device for displaying, and stops an alarm operation after receiving a confirmation instruction of a user on the alarm information.
8. The apparatus of claim 7, wherein the display device is configured to display the received alert information; when the current detection level value is restored to the detection level preset value, the exception report measuring point module sends a cancellation alarm instruction to the alarm module, the alarm module responds to the cancellation alarm instruction to send an alarm information display termination instruction to the display device, and the display device responds to the alarm information display termination instruction to stop displaying the alarm information.
9. A logic module detection method based on an enterprise management control system is characterized in that the method is applied to the enterprise management control system, the enterprise management control system comprises a plurality of internal logic modules and an exception report measuring point module, each internal logic module has a set logic value, and the exception report measuring point module has a detection level preset value;
the method comprises the following steps: converting the respective current logic values into level values through a plurality of internal logic modules and inputting the level values into the logic operation circuit respectively; performing logic operation on each level value through the logic operation circuit to obtain a level operation result, and sending the level operation result to the exception report measuring point module;
judging whether to change the current detection level value or not according to the level operation result through the exception report measuring point module, and sending an alarm signal to the alarm module when the current detection level value is not equal to the detection level preset value;
and receiving the alarm signal through the alarm module, and sending alarm information according to the alarm signal by the alarm module and carrying out alarm operation.
10. The method of claim 9, further comprising: the alarm information is pushed to a display device through the alarm module to be displayed, and after a confirmation instruction of a user on the alarm information is received, the alarm module stops alarm operation.
