The monitor comprises the principal machine, a keyboard board and a power module; the keyboard board comprises the keyboard controller, a hardware shutdown circuit, a software and hardware shutdown logic circuit, and a switch electrically connected with the keyboard controller and the hardware shutdown circuit; the keyboard controller and the hardware shutdown circuit are mutually electrically connected and perform two-way communication with the principal machine; and the software and hardware shutdown logic circuit is respectively and electrically connected with the keyboard controller and the hardware shutdown circuit and unidirectionally controls the power module.
Description
Technical field
This utility model relates to a kind of monitor with software and hardware shutdown function.
Background technology
At present people to the safety in utilization of the electronic product of medical field require increasingly highly, for example the shutdown function of medical monitor product needs more rigorous design, and existing monitor often under given conditions all can not normal shutdown.Existing monitor mainly comprises main frame and finger-board with the relevant parts of shutdown function; Present shutdown mode is after the operator is by the power key on the lower keyboard; Controller in the finger-board sends shutdown command and gives main frame, after the main frame feedback acknowledgment information, by controller control powered-down.But when the controller of main frame or keyboard breaks down or do not have under the situation of response, will cause this monitor can't normal shutdown, bring the inconvenience in the use to the operator.
The utility model content
This utility model technical problem to be solved is the deficiency that overcomes prior art, provide a kind of controller to break down when main frame or keyboard or do not have under the situation of response still can normal shutdown the monitor with software and hardware shutdown function.
The technical scheme that this utility model adopted is: this utility model comprises main frame, finger-board and power module; It is characterized in that: said finger-board comprises KBC, hardware shutdown circuit, software and hardware shutdown logic OR circuit and the switch that is electrically connected with said KBC, hardware shutdown circuit; Said KBC be electrically connected with said hardware shutdown circuit and with said main frame both-way communication, this software and hardware shutdown logic OR circuit is electrically connected and the said power module of unidirectional control with said KBC, hardware shutdown circuit respectively.When host work is normal, finger-board is in proper working order, and the user presses switch (being power key key), and the finger-board controller is according to the feedback decision shutdown of main frame; Work as hostdown, finger-board is in proper working order, and the user presses power key key, and behind host not responding or the response timeout, the finger-board controller is controlled shutdown voluntarily; Work as hostdown, during the finger-board fault, the user presses power key key, behind the finger-board controller response timeout, and above-mentioned hardware shutdown circuit control shutdown.
Further, be provided with timer in the said hardware shutdown circuit, when the user presses switch, pick up counting, judge whether to shut down according to the time of setting.
The beneficial effect of this utility model is: because said finger-board comprises KBC, hardware shutdown circuit, software and hardware shutdown logic OR circuit and the switch that is electrically connected with said KBC, hardware shutdown circuit; Said KBC be electrically connected with said hardware shutdown circuit and with said main frame both-way communication; This software and hardware shutdown logic OR circuit is electrically connected and the said power module of unidirectional control with said KBC, hardware shutdown circuit respectively; So this utility model both can be controlled the function that software and hardware shutdown logic OR circuit is realized the software shutdown through KBC, can realize that also hardware shutdown circuit control software and hardware shutdown logic OR circuit realizes the function of hardware shutdown; When the main frame of above-mentioned KBC or monitor all exists fault to respond, then can come forced shutdown through the hardware shutdown circuit, guarantee the normal shutdown of monitor product.
Description of drawings
Fig. 1 is the schematic block circuit diagram of this utility model.
The specific embodiment
As shown in Figure 1, this utility model comprises main frame, finger-board and power module, expression finger-board part in the frame of broken lines, and two parts are mainboard and power module in addition.Said finger-board comprises KBC, hardware shutdown circuit, software and hardware shutdown logic OR circuit and the switch that is electrically connected with said KBC, hardware shutdown circuit; Said KBC be electrically connected with said hardware shutdown circuit and with said main frame both-way communication, this software and hardware shutdown logic OR circuit is electrically connected and the said power module of unidirectional control with said KBC, hardware shutdown circuit respectively; Be provided with timer in the said in addition hardware shutdown circuit.
Be both-way communication between finger-board and the mainboard, finger-board is unidirectional control to power module, and promptly finger-board can be controlled the power module shutdown.In the actual use of monitor, following several kinds of shutdown situation are arranged:
1, host work is normal, and finger-board is in proper working order, and the user presses switch (power key key is hereinafter to be referred as key), and the finger-board controller is according to the feedback decision shutdown of main frame.
2, hostdown, finger-board is in proper working order, and the user presses key, and after response of host was overtime, finger-board shut down voluntarily.
3, hostdown, the finger-board fault, the user presses key, behind the finger-board controller response timeout, hardware shutdown circuit control shutdown.
Below just present embodiment is done further to set forth with more concrete example:
Setting finger-board, maximum to allow the time-out time of main frame be T1, and the hardware shutdown circuit is maximum, and to allow the time-out time of finger-board controller be T2, then T2>T1, be set, T2=5 second T1=3 second in the actual items.
Power key event handling flow process is following:
The user presses power key, and the timer in the hardware shutdown circuit picks up counting and waits for 5 seconds, and the finger-board controller recognizes shutdown request at once, and to main frame forwarding request, main frame is after the finger-board controller sends the affirmation shutdown, and the finger-board controller is controlled shutdown.
If main frame is not responded the shutdown request of finger-board in the above process in 3 seconds, then surpass 3 seconds, finger-board controller forced shutdown.
If not shutdown of finger-board controller after 3 seconds in the above process, then after 5 seconds, hardware shutdown circuit forced shutdown.
Possess on the Keyboard Control plate hardware shutdown circuit and software shutdown circuit or logic circuit; Be that hardware shutdown circuit and finger-board controller can independently be controlled the power supply shutdown; And shutdown time-delay T2 is set>T1 is in order to satisfy first soft-off, the logic demand of back hardware.
Claims (2)
1. monitor with software and hardware shutdown function; Comprise main frame, finger-board and power module; It is characterized in that: said finger-board comprises KBC, hardware shutdown circuit, software and hardware shutdown logic OR circuit and the switch that is electrically connected with said KBC, hardware shutdown circuit; Said KBC be electrically connected with said hardware shutdown circuit and with said main frame both-way communication, this software and hardware shutdown logic OR circuit is electrically connected and the said power module of unidirectional control with said KBC, hardware shutdown circuit respectively.
