Specifically, the call for help intercom system is introduced by taking a five-way intercom system as an example, as shown in fig. 1, the elevator distress fault alarm monitoring system comprises: monitoring devices, elevator mainboard, five side's intercom systems.
The monitoring device comprises a processor, an acquisition module 1, an acquisition module 2, a communication module and a power module; the processor is respectively connected with the acquisition module 1, the acquisition module 2, the communication module and the power module in a control mode.
The monitoring device of the present embodiment is typically installed in an elevator control cabinet.
The acquisition module 1 is connected with the elevator mainboard through a communication interface circuit, and acquires the running state information of the elevator in the elevator mainboard in real time, wherein the running state information comprises a fault state, a normal state and the like, and the fault state and the normal state comprise floor information, time information and the like.
The collection module 2 is responsible for being connected with L, R two ports of the computer room host of the five-party intercom system, collects the signal state information of the computer room host of the five-party intercom system in real time, and comprises the following steps: standby state, call state, and talk state. The three states of standby, call and talk are identified by the voltage change across L, R.
Specifically, as shown in fig. 2, the circuit diagram of the acquisition module 2 in this embodiment includes two positive and negative level detection branches and one level measurement branch.
The level measuring branch comprises a rectifying module D0 and a voltage regulator tube Z0; the alternating current side of the rectifying module D0 is connected with the L, R port of the call-for-help intercom system host, the direct current side of the rectifying module D0 is connected in parallel with a voltage stabilizing tube Z0, one end of the voltage stabilizing tube Z0 is grounded, and the other end of the voltage stabilizing tube Z0 is used as a detection output F3.
Two positive and negative level detection branches are mutually redundant, and one positive and negative level detection branch is taken as an example: the device comprises an optical coupling element U16, wherein the primary side of the optical coupling element U16 is connected in parallel with a L, R port of a host machine of the call-for-help intercom system, the upper end of the secondary side of the optical coupling element U16 is connected with a power supply through a pull-up resistor R51, the lower end of the secondary side of the optical coupling element U16 is grounded through a pull-down resistor R52, and the lower end of the secondary side of the optical coupling element. In fig. 2, R49, R50, R53, R54, R57, R58, R59, and R72 are all current limiting resistors.
In this embodiment, the specific determination method of the state information of the host collected by the collection module 2, in combination with the above circuit, includes:
1) when the collected voltage of the host L, R port of the five-party intercom system is zero, the five-party intercom system is judged to be in a standby state; when the voltage of the host L, R of the five-party intercom system is + V, the calling state is judged; when the collected voltage of the host L, R of the five-party intercom system is-V, the conversation state is judged, wherein V is about 10V; the specific combinations of the judgment logics are shown in table 1.
TABLE 1
| + V (Call status) | -V (Call status) | 0 (Standby state) | |
| F1 | Height of | Is low in | Is low in |
| F2 | Is low in | Height of | Is low in |
| F3 | Height of | Height of | Is low in |
2) When the standby voltage of the host R, L port of the five-way intercom system is not zero, the voltage value V is collected by the voltage measuring circuitADWhen V isAD＜VxJudging the state to be in a standby state; when V isADWhen the collected voltage of the port of the host L, R of the five-party intercom system is + V, the call state is judged; when V isADWhen the collected voltage of the port of the host L, R of the five-party intercom system is-V, the conversation state is judged; wherein V is the full voltage value, VXIs a voltage deviation threshold; the corresponding specific judgment logic combination is shown in table 2.

| F3 | Height of | Height of | VAD(VAD＜VX) |
Table 1 differs from table 2 only in the determination of the standby state. Specifically, in table 1, the voltage at the L, R port is 0, and both F1 and F2 are low.
In the case corresponding to Table 2, the measured value obtained at F3 is denoted as VADIn the standby condition, the port of the host R, L is not zero due to the mismatch of RL line impedance, and the level states of F1 and F2 are unstable, so if V is at this timeADAnd if the Vx is smaller than the Vx and is a set threshold value, the state is directly judged to be a standby state.
The reason why table 1 differs from table 2 is that there is a difference in L, R port voltage status among different five-way intercom system hosts.
Therefore, the acquisition module 2 in fig. 2 can stably acquire the state information of the host of the five-way intercom system. The two positive and negative level detection branches are redundant, the positive and negative level detection branches have the same structure and the same function, output detection values F1 and F2 of the two positive and negative level detection branches which are redundant can provide judgment information, and the high and low levels in the truth table are just opposite under the condition that the external wiring L, R is connected in the opposite direction. As another embodiment, only one positive/negative level detection branch may be provided.
