Detailed Description
The industrial personal computer which is powered on and off by utilizing an external power supply mainly has the problem that the power-off and power-off are not beneficial to the stability of the industrial personal computer.
In order to solve the problem, the technical idea of the utility model is that the battery is utilized to supply power when external power source is cut off suddenly to support the industrial computer to carry out relevant shutdown operation (for example, save file information, etc.), finally accomplish and shut down. Therefore, the industrial personal computer can reliably execute shutdown no matter normal shutdown or abnormal power failure, and various stability problems are avoided. In addition, after the external power supply is disconnected, if the power supply is quickly powered on again, the industrial personal computer cannot respond to power-on and cannot be powered on due to the fact that the power supply is powered on in the power-off and power-off process. Under this condition, the staff must wait for after shutting down completely, and the rethread is gone up the electricity and is started, and this has just influenced the convenience that the industrial computer used, consequently, the utility model discloses still detect the consumption of industrial computer to in time respond to start operation.
The technical solutions in the embodiments of the present disclosure will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present disclosure, and it is to be understood that the described embodiments are only some embodiments, but not all embodiments, of the present disclosure. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.
An industrial personal computer system as shown in fig. 1 comprises an industrial personal computer and a startup and shutdown control device. The on-off control device comprises a controller, an on-off detection module, a power consumption detection module, an on-off trigger module and a power management module. The controller samples the on-off of an external power supply through the on-off detection module, samples the power consumption condition of the industrial personal computer through the power consumption detection module, and controls the industrial personal computer to be started and shut down through the on-off trigger module; the power management module is used for switching power supply of an external power supply and power supply of the energy storage unit. The industrial personal computer comprises hardware such as a mainboard, a CPU, a hard disk and an internal memory, and the hardware is the same as that of a conventional industrial personal computer, so that the industrial personal computer is not described again. It should be noted that the industrial personal computer may be an industrial personal computer with a power on/off button, or an industrial personal computer that is completely powered on/off by an external power supply. External power source and energy storage unit pass through power management module and are connected with the industrial computer, and the break-make electricity detection module detects in real time, and when detecting the external power source outage, power management module control energy storage unit supplies power to the industrial computer. When the external power supply is powered off, the industrial personal computer executes shutdown operation, and the power is switched to the energy storage unit to supply power so that the industrial personal computer can smoothly complete the shutdown process.
In an application scene, when the industrial personal computer runs, the external power supply exists, the power consumption of the industrial personal computer is the starting power consumption, and the controller does not execute any control action. If the external power supply is disconnected, the controller triggers the industrial personal computer to shut down through the power on/off module, the industrial personal computer executes a shutdown action, and in the shutdown process, the energy storage unit supplies power to ensure that the shutdown process can be smoothly completed, so that the industrial personal computer has a shutdown protection function, and the stability of the industrial personal computer is improved.
Moreover, in the shutdown process, the power consumption of the industrial personal computer is not reduced to the shutdown power consumption, and after shutdown is completed, the power consumption of the industrial personal computer is reduced to the shutdown power consumption. If the power-off of the industrial personal computer is finished, the external power supply is connected again, namely the power of the external power supply and the power consumption of the industrial personal computer are simultaneously met under the condition that the power consumption of the industrial personal computer is the power-off power consumption, and the controller triggers the industrial personal computer to start through the power-on and power-off triggering module. In other words, since the shutdown process lasts for a certain time, if the external power supply is powered on again within the time, the industrial personal computer cannot respond to the startup because the power consumption of the industrial personal computer is not reduced to the shutdown power consumption. When the power consumption of the industrial personal computer is reduced to the power consumption of shutdown, namely after the shutdown process is completed, the controller can automatically trigger the industrial personal computer to be started. Therefore, the problem that the computer can not be restarted in the shutdown process and the computer can be started again by a worker after the shutdown process is finished is solved. Therefore, the on-off control device can realize the stable and reliable startup and shutdown of the industrial personal computer and is convenient for the operation of workers.

In one embodiment, the power on/off detection module for detecting whether the external power supply is powered off may employ a bidirectional optical coupling element, a primary side of which is connected to an ac side of the external power supply (i.e., collects an ac voltage of the ac input interface) and is configured to directly detect an external ac input voltage; for example, as shown in fig. 3, when there is an ac input from the outside, the secondary side of the bidirectional optical coupler element outputs a high level, and when the ac input from the outside is turned off, the secondary side of the bidirectional optical coupler element outputs a low level, and the controller determines whether there is an ac input from the outside by collecting the level state of the secondary side of the bidirectional optical coupler element.
In another embodiment, the power on/off detection module may employ a unidirectional optocoupler, and a primary side of the unidirectional optocoupler may be connected to a dc side of the external power output (i.e., the dc voltage output by the voltage reduction unit). For example, as shown in fig. 4, when the external power source normally outputs a dc voltage, the secondary side of the unidirectional optical coupling element outputs a high level, and when the external power source cannot normally output a dc voltage, the secondary side of the unidirectional optical coupling element outputs a low level, and the controller determines whether the external power source outputs a dc voltage by collecting a level state of the secondary side of the unidirectional optical coupling element. The two embodiments can judge whether the external power supply is powered off; in other embodiments, other types of devices may be used to detect the external power source, such as a voltage transformer, a current transformer, and so on.
In one embodiment, the power consumption detection module for detecting the power consumption of the industrial personal computer can be a current sensor and is connected with a load of the industrial personal computer. The current sensor can measure the current flowing through the load of the industrial personal computer, and the current flowing through the load of the industrial personal computer can indirectly reflect the power consumption condition of the industrial personal computer. The controller is connected with the current sensor in a sampling mode, so that power consumption of the industrial personal computer is detected. In particular, the current sensor may be implemented using a sampling resistor connected in series in the circuit. In other embodiments, the power consumption detection module can also be a combination of a current sensor and a voltage sensor so as to more accurately and directly measure the power consumption of the industrial personal computer. The detected power consumption value can be divided into power-on power consumption and power-off power consumption; for example, a smaller threshold is set, and if the threshold is smaller than the threshold, the power consumption is defined as the power consumption for shutdown, and if the threshold is larger than the threshold, the power consumption for startup is defined as the power consumption for startup.
And the power on/off triggering module is used for sending power on and off signals to the industrial personal computer so as to trigger the power on and off actions of the industrial personal computer. In particular, the power on/off triggering module may include various implementation forms. In one embodiment, the power on/off trigger module comprises a power on relay, a power off relay and a power off serial port; the controller is connected with a coil of the starting relay, the starting relay contact is connected with a starting port of the industrial personal computer, and when the controller enables the coil of the starting relay to be electrified, the starting relay contact is attracted so as to simulate manual starting action.

The shutdown serial port is a serial communication interface, and the serial communication interface of the controller is connected with the serial communication of the industrial personal computer, so that a shutdown signal output by the controller can be transmitted to the industrial personal computer. The serial communication interface can be an RS232 interface or an RS485 interface, and the RS232 interface or the RS485 interface of the industrial personal computer is configured to trigger the industrial personal computer to be powered off when receiving a power-off signal through programming. In other embodiments, the power on/off module may also be implemented by using other types of interfaces, which is not limited by the present invention.
