Technical field
The utility model relates to a kind of matrix form button manager, specifically, relates to a kind of matrix form button manager of realizing forbidding button, allowing the control and management functions such as button and elp button.
Background technology
Along with the development of society, the elevator use amount increases sharply, and it has become people's one of very important vehicle of going on a journey.In lift car, the passenger's is easy and simple to handle, quick in order to make, corresponding one of each floor is exhaled terraced button, and button generally has dual mode with being connected of keystroke handling device: a kind of is point-to-point mode, each button is by four line (power leads in this mode, ground wire, key wire, some lamp line) directly link to each other with the keystroke handling device one to one; Another kind of matrix form mode, as shown in Figure 1, all buttons logically are arranged in rows, row formula matrix, only need N root line RAi to be connected with the keystroke handling device with M root alignment CAj, just can obtain i * j and exhale terraced button Bij, the keystroke handling device sends as shown in Figure 2 impulse singla with the certain hour interval on line RAi, when button Bij is pressed, line RAi and alignment CAj short circuit, the keystroke handling device will detect this impulse singla at alignment CAj, thereby determine the position of button Bij, this matrix form press-key structure is simple, cost is low, and reliability is high, is used widely at more elevator and other equipment.But, not for the manager of matrix form button, do not realize in the existing matrix form button forbidding button, allowing the control and management functions such as button and elp button in the prior art.
The utility model content
The technical problems to be solved in the utility model is, a kind of matrix form button manager is provided, and realizes forbidding button, allows the control and management functions such as button and elp button.
The utility model is that the technical scheme that its technical matters of solution adopts is: a kind of matrix form button manager is provided, comprise signal processor, wherein, also comprise the column signal controller, described column signal controller comprises switch, described switch series is associated on the alignment, and the control end of described switch connects the output of signal processor, the input link information perceptron of described signal processor and row signal detector.
Above-mentioned matrix form button manager, wherein, described information Perception device is radio-frequency (RF) Reader, Fingerprint Identification Unit, retina recognizer, face recognition device or speech recognition device.
Above-mentioned matrix form button manager, wherein, described switch is semiconductor switch device or relay.
Above-mentioned matrix form button manager, wherein, described row signal detector inclusion test unit, this row detecting signal unit comprises optocoupler P, be connected to power supply after described optocoupler P the first terminal and the equal series resistance of the 3rd terminal, and optocoupler P the 3rd connecting terminals is received message handler, and the second terminal of described optocoupler P is connected with line, and the 4th terminal of described optocoupler P connects public terminal.
Above-mentioned matrix form button manager, wherein, the control end of described switch also connects the fire-fighting control line.
Compared with prior art, the utlity model has following beneficial effect: the matrix form button manager that the utility model provides, signal processor is by information Perception device identifying operation person identity, and the output corresponding control signal realizes forbidding button, allows the control and management functions such as button and elp button to the column signal controller.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the structural representation of existing matrix form mechanical key;
Fig. 2 is the impulse singla schematic diagram that the keystroke handling device sends at line RAi among Fig. 1;
Fig. 3 is the structural representation of a kind of matrix form button of the utility model manager.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with embodiment and accompanying drawing, the utility model is further described:
Referring to Fig. 3, the matrix form button manager that the utility model provides, comprise signal processor 203, wherein, also comprise column signal controller 204, described column signal controller 204 comprises switch, and described switch series is associated on the alignment, the control end of described switch connects the output of signal processor 203, the input link information perceptron 201 of described signal processor and row signal detector 202.Wherein, described information Perception device 201 is radio-frequency (RF) Reader, Fingerprint Identification Unit, the retina recognizer, face recognition device or speech recognition device, described switch is semiconductor switch device or relay, described row signal detector 202 inclusion test unit, this row detecting signal unit comprises optocoupler P, be connected to power supply after described optocoupler P the first terminal and the equal series resistance of the 3rd terminal, and optocoupler P the 3rd connecting terminals is received message handler, the second terminal of described optocoupler P is connected with line, the 4th terminal of described optocoupler P connects public terminal, when on the line impulse singla being arranged, optocoupler P the 3rd terminal test arrives this impulse singla, and the impulse singla that detects is passed to message handler 203.
During actual the use, keystroke handling device 100 interval transmitted signals are to line, and row signal detector 202 detects the impulse singla on the corresponding line and is input to signal processor 203.When having the operator will use this matrix form button, information Perception device 201 first key range operators' identity, again identity information is sent to signal processor 203, signal processor 203 is according to the authority of this identity information verification operation person to each button operation, decision is to allow this operator by part button or whole button, still forbid button, perhaps directly help its button according to operator's identity.When allowing this operator by part button or whole button, the switch sections of connecting with alignment in the signal processor 203 master cock controllers 204 or all closed, and the closure of described switch is synchronous with the impulse singla on the corresponding line; When forbidding button, the switch of connecting with alignment in the signal processor 203 master cock controllers 204 all disconnects, and button is invalid; When carrying out the elp button function, signal processor 203 is closed according to the respective switch that operator's identity information will be connected with alignment, and the closure of described switch is synchronous with the impulse singla on the corresponding line, and automatically cancellation realizes automatic keying after time-delay a period of time.In addition, the control end of described switch also connects the fire-fighting control line, and when having fire accident to occur, the fire-fighting control line makes the switch of connecting with alignment all closed, automatically cancels button control function.
In sum, the matrix form button manager that the utility model provides, signal processor is by information Perception device identifying operation person identity, and the output corresponding control signal realizes forbidding button, allows the control and management functions such as button and elp button to the column signal controller.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
