The specific embodiment
As shown in Figure 1, the present invention relates to a kind of input method of functional safety plate inspecting state, described method specifically may further comprise the steps based on inspection switch, master controller:
Step (1) impulse singla is by the input port of inspection switch input master controller;
The input port of the described master controller of step (2) receives the delivery port of impulse singla by master controller and is sent to the functional safety plate;
The described functional safety plate of step (3) judges the impulse singla that receives, and when the functional safety plate receives impulse singla N time that pre-sets frequency when several, then enters inspecting state, and N is the natural number more than 1; When the functional safety plate is not received this frequency pulse, then withdraw from inspecting state immediately.
In addition, in the master controller of described step (2), set one and be used for the frequency predetermined value that reset signal is judged, the impulse singla that receives when the input port of master controller satisfies the frequency predetermined value of reset signal, and then described master controller resets to the functional safety plate; The impulse singla that receives when the input port of master controller does not satisfy the frequency predetermined value of reset signal, and the delivery port of master controller transfers to the functional safety plate with described impulse singla.
As shown in Figure 2, concrete working process of the present invention is as follows:
At first, escalator or moving sidewalk receive the model selection pin that is input to the functional safety plate behind the state of inspection switch, and the functional safety buttress is confirmed current mode of operation according to the input of this pin;
Impulse singla is imported master controller by inspection switch; Master controller receives the state of inspection switch, and the mode with pulse sends to the functional safety plate with this state then; The functional safety plate preestablishes the frequency of impulse singla, and pre-set herein frequency is the repair rate that defines in the system design process, and as 100HZ or 150HZ, this frequency in use remains unchanged.The functional safety plate is judged the impulse singla that receives: when the functional safety plate receives the certain number of times of impulse singla that pre-sets frequency, enter inspecting state; In case do not receive this frequency pulse, then withdraw from inspecting state immediately.
In master controller, set one and be used for the frequency predetermined value that reset signal is judged.Reset signal herein is the signal of mainboard reset function safety guard.The outside signal master controller that resets, master controller sends corresponding reset signal to the functional safety plate when oneself resets.I.e. resetting by main controller controls functional safety plate.The Rule of judgment of reset signal can be the pulse of certain frequency.The impulse singla that receives when the input port of master controller satisfies the frequency predetermined value of reset signal, then the functional safety plate is carried out to reset; The impulse singla that receives when the input port of master controller does not satisfy the frequency predetermined value of reset signal, and the delivery port of master controller transfers to the functional safety plate with described impulse singla.Namely when reset condition was satisfied in input, then execution resetted; If when the signal of receiving does not satisfy reset signal when the satisfied maintenance signal of incoming signal yet, enter automatic running state.
