[0028] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0029] The technical solutions provided by various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0030] Figure 1 A module schematic diagram of an embedded high-voltage integrated module provided for one or more embodiments of this specification. The module is applied to automated machine tool equipment, and integrates functions such as electrical parameter acquisition and measurement, temperature monitoring, switch control, over-limit alarm, network communication, and fault warning, so that users can comprehensively manage and monitor the equipment power system through a high-voltage integrated module platform, reducing the complexity of the system. The implementation of the analysis method involved in the embodiments of the present application can be a terminal device or a server, and the present application does not impose any special restrictions on this. For the convenience of understanding and description, the following embodiments are described in detail using the server as an example. It should be noted that the server can be a single device or a system composed of multiple devices, that is, a distributed server, and the present application does not impose any specific restrictions on this.

[0031] like Figure 1 As shown, an embodiment of the present application provides an embedded high-voltage integrated module, including: a main control unit, a temperature measurement unit, an electrical parameter acquisition unit, and a human-computer interaction unit.

[0032] Among them, the main control unit is composed of a microprocessor and peripheral circuits, and is connected to the human-computer interaction unit, the electrical parameter acquisition unit, and the temperature measurement unit. It is used to receive key input information from the human-computer interaction unit and realize switch control according to the key input information; it is also used to receive parameter information from the electrical parameter acquisition unit and the temperature measurement unit, and perform risk analysis on the parameter information, and issue early warnings based on the analysis results.

[0033] The electrical parameter acquisition unit here includes an electric energy metering chip and an electric parameter acquisition circuit, wherein the electric parameter acquisition circuit includes a current sampling circuit and a voltage sampling circuit, and the voltage sampling circuit is an RC series-parallel circuit, including multiple series resistors, wherein the multiple series resistors are used for voltage division, so that the voltage input to the electric energy metering chip is within a preset range. The current sampling circuit is an RC series circuit, and the output voltage of the current sampling circuit is equal to the input voltage. When realizing the electric parameter acquisition and measurement function, it is mainly realized by using a filter rectifier circuit, a PGA programmable gain amplifier and an AD conversion. Through the parameter information of the measured electric parameter, the system will analyze the power consumption status of the system in real time, and compare the measured parameter with the set threshold value. If the measured parameter exceeds the set threshold value, the system will shut down the corresponding circuit. If the system detects that the measured parameter is disturbed, the system will issue an early warning.

[0034] The temperature measurement unit here includes a temperature measurement circuit, in which a thermistor and a voltage divider resistor are arranged. The temperature measurement function is mainly realized by using an NTC thermistor, which is used to monitor the temperature state of the equipment power system. Compared with common temperature sensors, NTC thermistors are more suitable for economical products and have lower costs.

[0035] like Figure 2 As shown, the over-limit alarm means that when the measured data is abnormal (such as the measured parameter is detected to exceed the set threshold, disturbance occurs, etc.) or an electrical accident occurs (such as the module detects overcurrent, short circuit, etc.), the system will issue an alarm and shut down the corresponding fault circuit.

[0036] The human-machine interaction unit includes a display subunit and a key subunit, which are used by the user to select corresponding functions and display information, such as manually cutting off the corresponding circuit and switching the display of parameters such as temperature, voltage, current, power, etc. In one embodiment, the key subunit includes multiple independent keys, and the idea of ​​a state machine is adopted in the software, which can realize short pressing, long pressing, and double clicking of multiple independent keys. (5) The human-machine interaction interface is equipped with a multi-level menu, which can display parameters such as current, voltage, and ambient temperature of the corresponding circuit.

[0037] In one embodiment, the embedded high-voltage integrated module provided in the present application also includes a power supply unit, where the power supply unit includes a 220V to 12V switching power supply module, a TPS5430DDAR switching power supply chip, an 1117 linear regulator and a TL431 reference voltage source, which are used to power the embedded high-voltage integrated module.

[0038] In one embodiment, the embedded high-voltage integrated module further includes a communication unit; the communication unit is connected to the main control unit and is used to upload the parameters received and analyzed by the main control unit to the cloud in real time to realize network communication function, and the server can also issue instructions to the module to realize remote control. Figure 3As shown, after the high-voltage integrated module obtains the parameters, the module will display the parameters on the human-computer interaction interface in real time and transmit them to the cloud.

[0039] In one embodiment, in order to realize the switch control function, the embedded high-voltage integrated module further includes a switch control unit connected to the main control unit, wherein the switch control unit is composed of multiple power relays and a Darlington transistor, and the Darlington transistor is used to drive the multiple power relays, and the multiple power relays are respectively arranged in multiple circuit channels. The switch control unit is used to receive key input information from the main control unit, and control the opening and closing of multiple circuit channels according to the key input information. Figure 4 As shown, after receiving the key input, the main control unit will send a control signal to the coil of the corresponding channel relay to realize the switch control of the corresponding channel.

[0040] Furthermore, considering that sparks may be generated when the relay contacts are disconnected, RC spark suppression circuits are provided in multiple circuit channels of the present application, where the RC spark suppression circuits are used to absorb the induced electromotive force when the contacts are disconnected.

[0041] like Figure 5 As shown in the figure, the switch control unit is mainly composed of 5 power relays, which are driven by a Darlington transistor, and each channel is equipped with a corresponding spark suppression circuit. The Darlington transistor is responsible for improving the driving ability of the output signal of the main control unit, thereby allowing the main control unit to control the relay module. The RC circuit connected in parallel at both ends of the relay contact is a spark suppression circuit. When the relay is switched, according to Lenz's law, an induced electromotive force will be generated at both ends of the coil. This induced electromotive force will be superimposed on the input voltage, and a large voltage will be generated at both ends of the coil. When this voltage reaches a certain threshold, sparks will be generated at the relay contacts. The spark suppression circuit can absorb the induced electromotive force when the contacts are disconnected, which can suppress the generation of sparks to a certain extent.

[0042] In one embodiment, Figure 6 As shown, the display subunit includes a plurality of quadruple digital tubes and a digital tube driving chip; the digital tube driving chip here is used to drive the plurality of quadruple digital tubes, and the display subunit can reduce the occupancy of the IO port.

[0043] In one embodiment, the high voltage integrated module includes a high voltage area and a low voltage area. The high voltage area and the low voltage area are isolated during quality inspection to prevent high voltage from destroying low voltage devices.

[0044] In one embodiment, the high-voltage integrated module includes a digital signal region, an analog signal region, and a transition region, and the transition region is used to prevent interference between the digital signal and the analog signal.

[0045] In one embodiment, each channel of the module is subjected to special treatments such as double-sided routing, window opening, tinning, and soldering of copper wires on the PCB, so that it can withstand large currents and high voltages.

[0046] like Figure 7 As shown, the high-voltage integrated module obtains real-time electrical parameters by using an electric energy metering chip and a corresponding electrical parameter acquisition circuit. The current sampling resistor uses a 1 milliohm high-power sampling resistor, so that the channel can withstand a large current. The electrical parameter acquisition circuit is divided into a current sampling circuit and a voltage sampling circuit.

[0047] Voltage sampling circuit: The voltage sampling circuit can be regarded as an RC series-parallel circuit. First, the voltage input to the electric energy metering chip is within an appropriate range through multiple series resistors for voltage division. Secondly, the RC series-parallel circuit can also filter noise to make the measured parameters more accurate.

[0048] Current sampling circuit: The current sampling circuit can be regarded as an RC series circuit. Through time domain analysis of the RC circuit, it can be obtained that the output voltage of this circuit is equal to the input voltage. By setting the resistor voltage divider and the internal gain coefficient of the energy metering chip, the voltage input to the current channel of the energy metering chip can be at a suitable value.

[0049] like Figure 8 As shown, the power supply circuit of the high-voltage integrated module consists of a 220V to 12V switching power supply module, a TPS5430DDAR switching power supply chip, an 1117 linear regulator, and a TL431 reference voltage source, which are used to power the module.

[0050] like Fig. 9 As shown in the figure, the temperature measurement circuit is mainly composed of NTC thermistors, which are used to collect temperature parameters. The temperature measurement circuit adopts the form of a voltage divider circuit, in which the change in the resistance of the thermistor is converted into a change in voltage. The changed voltage is input to the main control unit through AD conversion and calculated.
