In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the framework schematic diagram of Elevator weight sensor buffer distance automatic checkout equipment of the present utility model;
Fig. 2 is the framework schematic diagram of the signal gathering unit of Elevator weight sensor buffer distance automatic checkout equipment of the present utility model;
Fig. 3 is the framework schematic diagram of the signal conversion output unit of Elevator weight sensor buffer distance automatic checkout equipment of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.
Consult shown in Fig. 1, Elevator weight sensor buffer distance automatic checkout equipment of the present utility model, comprise signal gathering unit 1, signal conversion output unit 2, master control board 3, door opening and closing system 4 and elevator drive system 5, signal gathering unit 1 is for detection of the counterweight buffer distance of elevator, in the time that counterweight buffer distance is less than setpoint distance, signal gathering unit 1 is sent signal, the signal that signal conversion output unit 2 sends for receiving signal gathering unit 1, and send and control signal to master control board 3, master control board 3 moves for reception control signal master cock door system 4 and elevator drive system 5.In the utility model, master control board 3 master cock door systems 4 open the door or close the door, and control elevator drive system 5 and export or do not export, and wherein, master control board 3 is not exported by producing failure code control elevator drive system 5.The setpoint distance of the counterweight buffer distance of elevator is preferably 150mm, also can be according to actual conditions, set other suitable distance.
Consult shown in Fig. 2, signal gathering unit 1 comprises signal detection magnetic switch 6, and signal detection magnetic switch 6 is for detection of the counterweight buffer distance of elevator.
Consult shown in Fig. 3, signal conversion output unit 2 comprises active voltage 7, source switch 8, often opens passive signal 9 and normally closed passive signal 10, and wherein, active voltage 7 is DC24V.When signal conversion output unit 2 receives the signal that signal gathering unit 1 is sent, passive signal 9 closures are exported, often opened to active voltage 7 and normally closed passive signal 10 disconnects.Signal conversion output unit 2 also comprises relay indicating light 11, fault-indicating lamp 12, when source switch 7 is opened, relay indicating light 11 is bright, when signal conversion output unit 2 receives the signal that signal gathering unit 1 sends, fault-indicating lamp 12 is bright, has reached and need not check that the failure code of mainboard also just can judge the object at elevator faults place very intuitively.
