Thus, in this system, the elevator does not respond to the call signal when there is only an object in the car and no person, without other verification procedures.
Preferably, when the signal processing and sending module collects the call signal of the same-floor call system, no matter what kind of signal is collected by the sensing system, the signal processing and sending module directly sends the call signal to the car control system, and under the condition of the call, the car door is directly opened.
Preferably, the sensing system comprises a light curtain sensor and a portrait sensor, wherein the light curtain sensor collects and identifies objects in the compartment, and the portrait sensor collects and identifies human bodies in the compartment. The light curtain inductor can accurately identify objects, the portrait inductor can accurately identify human body signals, the portrait inductor and the portrait inductor are mutually cooperated, the condition inside the car can be accurately judged, and therefore the signal processing and the sending module can accurately judge whether the car meets the operation requirement or not, and the stability and accuracy of the system can be improved.
Preferably, the signal processing and sending module includes a signal processing and sending module I, the light curtain sensor and the portrait sensor send the collected signals to the signal processing and sending module I, and the signal processing and sending module I compares the signals with preset signals: when the light curtain sensor and the portrait sensor do not collect signals, an air compartment signal is formed and sent; when only the object in the compartment is collected, an object signal is formed and sent; when a person is collected in the compartment, a person signal is formed and sent.
Preferably, the signal processing and sending module further comprises a signal processing and sending module II, and the signal processing and sending module II collects the call signal of the call calling system and the signal generated by the signal processing and sending module I, and compares the signals with a preset signal: under the condition of acquiring the call signal, when acquiring an empty car signal or a human signal, forming an obstacle-free signal, wherein the car runs, and when acquiring an object signal, forming an obstacle signal, wherein the car does not run.

Detailed Description
Embodiments of the present application will be described in detail with reference to the drawings and examples, so that how to implement technical means to solve technical problems and achieve technical effects of the present application can be fully understood and implemented.
Fig. 1 is a schematic diagram of an elevator control system provided by the present invention, which includes a car control system and call systems provided at respective floors, wherein the car control system controls the operation of a car. The system also comprises a sensing system positioned in the car, wherein the sensing system specifically comprises a light curtain sensor and a portrait sensor, the light curtain sensor collects and identifies objects in the car, and a zero signal S is sent when no object is in the car0Transmitting object signal S in the presence of an object1(ii) a The human image sensor collects and identifies human body in the compartment, and sends zero signal S when no person is in the compartment0When a person is in the carriage, a person signal S is sent2And the light curtain sensor and the portrait sensor send information to the signal processing and sending module I. The signal processing and transmitting module I compares the two collected signals with preset signals: when the signals sent by the light curtain sensor and the portrait sensor are S0+S0Form and transmit an empty-car signal a0(ii) a When the signals sent by the light curtain sensor and the portrait sensor are S1+S0Then, an object signal a is formed and transmitted1(ii) a When the signals sent by the light curtain sensor and the portrait sensor comprise S1Then, a human signal a is formed and transmitted2. That is, the light curtain sensor and the portrait sensor which respectively collect the object image and the portrait simultaneously send the collected signals to the signal processing and sending module I, and the signal processing and sending module I carries out contrast processing to form a single signal a0Or a1Or a2Thereby facilitating subsequent information identification.
As mentioned above, the signal a to be generated by the signal processing and transmitting module I0Or a1Or a2And the signal is sent to a signal processing and sending module II, and in the elevator control system, the signal processing and sending module II simultaneously receives a calling signal S of a calling system3The signal processing and sending module II is used for calling the elevator signal S3With the received car signal a0Or a1Or a2Comparing with the preset signal, and when the received signal is S3+a0Or S3+a2Generating a clear signal b1When the received signal is S3+a1Then, an obstacle signal b is generated2。
The signal processing and sending module II sends the generated signal to the signal processing and sending module III, and the signal processing and sending module II presets a starting signal K which can be identified by the car control system1And disable signal K2The signal processing and transmitting module III is used for collecting the barrier-free signals b1Is converted into an enabling signal K1The elevator calling control system sends the elevator calling signals to the elevator car control system, the elevator car control system controls the elevator car running mechanism to run at the moment, and the elevator car responds the elevator calling signals of passengers; the signal processing and transmitting module III collects the barrier signals b2Is converted into a disable signal K2And the control signal is sent to a car control system, the car control system prohibits the running of the car running mechanism at the moment, and the car does not respond to the call signal of the passenger under the condition that no other verification signal exists to enable the running of the car running mechanism, namely, the call fails.
In the running process, the car and the calling person are not on the same floor, namely F1≠F2. The significance of this call system in this case is that passengers are prohibited from placing objects (including animals) in the car, and do not travel with them, and attempt to transport the objects to the destination floor and take them out by means of calls by the person at the destination floor. When F is present1＝F2In the process of putting a plurality of objects into the elevator respectively, if the passenger has a plurality of objects, the elevator door is closed in a limited time, so that the door can be closed without moving the objects completely, and at the moment, the elevator does not respond to the call signal of the other floor but can respond to the call signal of the same floor.
The elevator control system is different from the existing elevator control system in that an induction system in a car is added, people/object information in the car and a call signal jointly determine whether the call is successful or not by acquiring information in the car, and under the condition that no additional verification information is set, once only an object exists in the car, the elevator system does not respond to the call signal of the other floor. Under the control logic of the system, other verification channels can be additionally arranged on the elevator, so that the use mode of the elevator in special occasions is standardized, and illegal operation is avoided and prevented.
