Detailed Description
In order to more clearly describe the present invention, the present invention will be further described with reference to the accompanying drawings.
Specifically, the complete machine equipment power-off system based on the identification of the shutdown state of the industrial control host is applied to self-service equipment provided with the industrial control host, referring to fig. 1, wherein the industrial control host 1 comprises a power module 11 and a serial port 12; the power supply module 11 is electrically connected with the MCU information processing module 3 and the on-off state monitoring module 2;

The physical serial ports of the industrial control host have a specific data transmission function; when the industrial control host works, information flow and communication data are transmitted through a physical serial port, but the information flow is captured and the data flow is monitored to identify the running state of the industrial control host, so that the working running of the industrial control host is influenced, and irreversible packet loss of the data can be caused; on the basis, the prior art also indicates a plurality of methods for identifying the operating state of the industrial control host by discriminating and judging the data stream in a software mode; and in this application, the real-time voltage of following the physics serial ports of making a new way starts, whether the system of judging the industry control host computer through the undulant condition of voltage closes, the system of industry control host computer closes the back, the voltage value of serial ports falls the power failure, when undulant non-operating voltage's scope, the power on off state monitoring module just can judge that the industry control host computer has closed through the voltage value of serial ports, then carry out the outage by MCU information processing module control power module to self-service equipment's complete machine and handle.
The voltage range of each pin of the serial port when the industrial personal computer normally works, namely the working voltage range, is stored in the set on-off state monitoring module, the pin function in the serial port of the industrial personal computer is completely defined, so the voltage range of the industrial personal computer at the working moment is also certain, but the current judgment and the voltage judgment are different, and because in the use of the serial port or the USB port of the industrial personal computer, the digital signal transmitted by the port transmits the signal by using high and low levels, the identification signal is extracted from the circuit, only the voltage change of the high and low levels can be identified, and the change of the current is too small to be monitored by the current.
In the present embodiment, please refer to fig. 4, the power module 11 includes a power supply unit 111 and an AC220V on-off control unit 112; the first end of the power supply unit 111 is connected with an AC220V power supply, the second end of the power supply unit 111 is connected with an AC220V on-off control unit 112, and the second end of the AC220V on-off control unit 112 is connected with self-service equipment; and the AC220V on-off control unit 112 performs the power-off process of the self-service device by the power-off signal of the MCU information processing module 3. In order to meet the requirement that the power supply of the whole self-service terminal equipment can be switched on and off from a 220V power supply at an input end, namely the power supply of the whole self-service terminal equipment is switched off, an AC220V on-off control unit is required to directly receive a power-off signal sent from an MCU information processing module, so that the power supply of the whole self-service equipment is switched off, and the system and the power supply of an industrial control host are not only switched off, wherein the MCU information processing module is specifically an MCU processing chip.
In this embodiment, please refer to fig. 3, a first end of the on/off state monitoring module 2 is connected to a TXD pin of the serial port 12 to obtain a real-time voltage value of the TXD pin; and the startup and shutdown state monitoring module 2 prestores a TXD pin working voltage range, and the state of the industrial control host is judged according to the real-time voltage value of the TXD pin. In this application, the most important is to use a power on/off state monitoring circuit:
referring to fig. 3, the circuit couples the cathode of the diode D1 to the TXD pin of the serial port, the first end of the first resistor R1 is coupled to the AD pin of the MCU chip, the second end of the second resistor R2 is coupled to the connection points of the first capacitor C1, the second resistor R2 and the third resistor R3, wherein the other ends of the capacitor C1 and the resistor R2 are connected to the 5V power output terminal; the other end of the third resistor R3 is coupled to a connection point of the anode of the diode D1 and the second capacitor C2, wherein the other end of the second capacitor C2 is grounded; the second resistor R2 and the third resistor R3 form a voltage dividing circuit, and when the master control is in a power-on state, the voltage of the serial port TXD pin is from-3V to-15V. Firstly, a lead wire which is coupled between the first end of the first resistor R1 and the MCU chip is defined as a T2 point, a connecting point of the first resistor R1 and the first capacitor C1 is defined as a T1 point, and the potential of the T1 is smaller than 2.5V; when the industrial control host is in a shutdown state, the voltage of the serial TXD pin is greater than or equal to 0V, and the potential of T1 is greater than 3.3V at the moment. The capacitor C1, the resistors R2 and R3 form a low-pass filter circuit, the second capacitor C2 and the diode D1 form a rectifying filter circuit, and the voltage fluctuation at the T1 point cannot be caused by the transient voltage change of the TXD pin. That is, a small range of fluctuation in normal operation does not cause erroneous judgment of the switching state detection circuit.
Because the point T2 is connected to the AD pin of the MCU chip, and the pin is in a high impedance state when being an input port, the potentials of the point T1 and the point T2 are the same, and the running state of the serial port can be directly identified from the monitoring of the point T2; when the MCU identifies that the potential at the point T2 is less than 2.5V, the voltage of the TXD pin is the working state voltage, and the master control is judged to be in a starting state; when the MCU recognizes that the potential at the T2 point is greater than 3.3V, the TXD pin voltage is a non-working state voltage, and the industrial personal computer is judged to be in a shutdown state.
In a more preferable scheme, referring to fig. 2, in order to ensure that the potential measurement at the point T2 is true and reliable, a timestamp is specially provided to ensure the monitoring accuracy, and it is determined that the industrial host is in the shutdown state only when it is determined that the potential of the T2 is greater than 3.3V and remains above 1S. That is, the time unit 21 is arranged in the on-off state monitoring module 2, when the voltage value of the TXD pin fluctuates suddenly outside the working voltage range of the TXD pin, the time unit marks the initial time on the timestamp, and marks 1 to 3S from the initial time as the response time period, the real-time voltage value of the TXD pin does not fall into the working voltage range of the TXD pin in the response time period, and then the off state signal is sent to the MCU information processing module.
When the scheme is implemented, the specific wiring process is that an AC220V power supply of the self-service equipment is connected to the power supply unit 111, then the power supply unit supplies power to the whole self-service equipment, wherein the power supply unit 111 is controlled by the AC220V on-off control unit 112; and one end of the AC220V on-off control unit 112 is connected with the MCU information processing module 3, and the MCU information processing module controls the AC220V on-off control unit, thereby controlling the on-off of the power supply unit and achieving the purpose of cutting off the power supply of the whole machine. And one end of the MCU information processing unit is connected with a startup and shutdown state monitoring unit, whether the TXD pin of the serial port is in a working state or not is judged through the potential monitoring of the T2 point, so that whether the system of the industrial control host is in a shutdown state or not is judged, and when the startup and shutdown monitoring unit judges that the industrial control host is in the shutdown state, the MCU information processing module is used for conducting overall power-off processing.
The method comprises the steps that the voltage of the USB interface is monitored, the first end of a startup and shutdown state monitoring module is connected with the USB interface, the real-time voltage value of the USB interface is received, the real-time voltage value of the USB interface is matched with the working voltage range of the USB interface, and the running state of the industrial control host is obtained; the second end of the on-off state monitoring module is connected with the MCU information processing module; and the MCU information processing module receives that the industrial control host is in a shutdown state, and controls the power supply module to stop supplying power to the self-service equipment.

and the MCU information processing module controls the power supply module to close the power supply of the autonomous device according to the shutdown state.
Preferably, when the power module is connected to an external power supply, the power supply unit is connected to the AC220V power supply, and the AC220V on-off control unit performs power-off processing when receiving the power-off signal sent by the MCU information processing module.
