The application relates to an emergency brake release power supply circuit and equipment. The circuit comprises a control module, a switching component, a first power supply circuit and a second power supply circuit; the control module turns on the connection between the first power supply circuit, the second power supply circuit and the corresponding interface equipment through the switching component, so that, in the case of normal power supply, the control module controls the first power supply circuit to supply power to the equipment standby battery, and in the case of monitoring the corresponding signal, the control module controls the first power supply circuit to provide power supply for the equipment control system, and controls the second power supply circuit to supply power to the brake holding coil; in the case of abnormal power supply, if the corresponding signal is monitored, the equipment standby battery provides power supply for the equipment control system through a DC-DC converter, and the control module controls the first power supply circuit to supply power to the brake holding coil through the switching component. Thus, the application simplifies the circuit, realizes the cost reduction through the reuse and normalization of the circuit.

The application provides a core shooting machine intelligent production system and method, and relates to the technical field of core shooting machine production. The core shooting machine intelligent production system comprises a core box recognition module, a lower computer, a PLC control module and an upper computer. The core box recognition module is used for recognizing a core box, and the lower computer is used for performing lower operation actions on the core box. The PLC control module is used for collecting actual production parameters of the core box. The upper computer is used for setting initial production parameters and correcting production parameters according to the actual production parameters. The PLC control module is also used for transmitting the production parameters and the corrected production parameters to the lower computer. Compared with the prior art, the application collects and transmits data parameters through the PLC control module, and sets parameters through the upper computer, so that data control is realized, the automatic production of the core shooting machine is realized, the process operation time is reduced, the production efficiency is improved, and the production cost is reduced.
