Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the following detailed description of the embodiments of the present application will be given with reference to the accompanying drawings. However, those of ordinary skill in the art will understand that in various embodiments of the present application, numerous technical details have been set forth in order to provide a better understanding of the present application. The claimed application may be practiced without these specific details and with various changes and modifications based on the following embodiments.
The implementation details of the verification method of the elevator door lock detection system of the present embodiment are exemplified below. The following is merely an implementation detail provided for ease of understanding and is not necessary to practice the present embodiments.
The checking method of the elevator door lock detection system provided by the application can be suitable for elevators with different models and different electric loops, and can be used for checking a plurality of elevator door lock detection systems at the same time. It should be noted that, the current elevator door lock detection system is generally embedded in an elevator controller, the elevator controller is used for obtaining the fault condition of the elevator door lock, and the detection result of the elevator door lock detection system is to be checked, at present, a manual checking method is often adopted, namely, the door lock is manually short-circuited and/or bridged, and then each door lock fault condition is checked in sequence. And those skilled in the art will appreciate that elevator door locks include single door locks, double door locks, multi-door locks. For a common single door lock, as shown in fig. 1a, there are 6 door lock fault conditions including: 1-2 short, 2-3 short, 1-3 bridge, 1-2 short and 2-3 short, 1-2 short and 1-3 bridge, 1-2 short and 2-3 short and 1-3 bridge. For a common double door lock, the door lock loop is shown in fig. 1b, and 1023 door lock faults exist. If the detection result of the elevator door lock detection system of the double door locks is to be checked, each door lock fault condition needs to be tested by using a manual wiring mode, time and labor are wasted, the operation is complex, in addition, the elevator door locks are different in elevator door lock loops due to different models and brands, and operators are required to have stronger professional knowledge. At present, a verification method which is wide in application range, high in efficiency, low in cost and simple to operate is lacking.
The embodiment of the invention relates to a verification method of an elevator door lock detection system, as shown in fig. 2, comprising the following steps:
And step 201, sending a short circuit command and/or a bridging command to the elevator door lock according to preset door lock detection loop information.
In this embodiment, the elevator door lock includes: a plurality of hall locks and a plurality of door car locks. The shorting command includes one or more of: a hall door lock short circuit and a door car door lock short circuit; the bridge command includes one or more of the following: hall door lock bridge, door car door lock bridge, hall door lock and door car door lock bridge. Of course, the specific shorting and bridging commands will vary in number and in detail from elevator to elevator of different types. When the door lock switch is closed, the elevator door is closed, and when the door lock switch is opened, the elevator door is opened.
Specifically, taking a double door lock elevator as an example, reference may be made to fig. 1b, the elevator door lock comprising: the front door lock, the front door car lock, the rear door lock and the rear door car lock are in short circuit. Thus, the shorting command may include one or more of the following: front hall door lock short circuit (1-2 short circuit), front door sedan-chair lock short circuit (2-3 short circuit), back hall door lock short circuit (3-5 short circuit), back door sedan-chair lock short circuit (5-6 short circuit). And the bridge command may also include one or more of the following: the front hall door lock head end and the front door car door lock tail end span (1-3 span), the front hall door lock head end and the rear hall door lock tail end span (1-5 span), the front hall door lock head end and the rear door car door lock tail end span (1-6 span), the front door car door lock head end and the rear hall door lock tail end span (2-5 span), the front door car door lock head end and the rear door car door lock tail end span (2-6 span), and the rear hall door lock head end and the rear door car door lock tail end span (3-6 span).
In an embodiment, before step 201, the method may further include: acquiring the connection relation of the elevator door lock; determining the number and the positions of detection interfaces according to the connection relation of the elevator door locks; and determining a door lock detection loop of the elevator door lock according to the number and the positions of the detection interfaces.
Specifically, the acquired connection relationship of the elevator door lock may be an elevator door lock loop diagram, or may be a connection relationship expressed by a text or symbol form. The number and the positions of the detection interfaces can be rapidly determined according to the connection relation of the elevator door locks, and the door lock detection loop of the elevator door locks can be determined according to the number and the positions of the detection interfaces. And correspondingly sending a short circuit command and/or a bridging command according to the determined door lock detection loop.
It should be noted that, the checking method of the elevator door lock detection system of the present application can be applied to both real elevators and elevator door locks simulated by the output points of the programmable logic controller. When the application is applied to a real elevator, a corresponding detection interface is arranged in an elevator door lock according to the determined door lock detection loop; when the application is applied to the elevator door lock simulated by the output point of the programmable logic controller, the dry contact can be used as a detection interface, the dry contact is an electric switch, the switch has two states of closing and opening, no polarity exists between the two contacts of the dry contact, and the two contacts can be interchanged.
Specifically, taking a double door lock as an example, the determined door lock detection loop is shown in fig. 3, and in fig. 3, all detection ports of the PLC-Y, PLC-COM are detection interfaces. By sending a shorting command and/or a bridging command to the elevator door lock, the detection interfaces can be controlled to close to realize the shorting or bridging of the door lock. Therefore, the simulation of the fault conditions such as elevator door lock short circuit and/or bridging can be realized by sending a command according to the door lock detection loop information as long as the door lock detection loop information is obtained, that is, the verification method can automatically complete the test of all door lock fault conditions as long as the verification program is written in advance, and the operation is simple, quick and convenient, and no manual wiring is needed.
In this embodiment, the programmable logic controller outputs a point, i.e., a PLC output point. The PLC (Programmable Logic Controller, PLC) is a programmable logic controller. The PLC generally consists of functional units such as a CPU, an instruction and data memory, an input/output interface, a power supply, and digital-to-analog conversion. The output unit is also a connecting part between the PLC and the controlled equipment, and has the function of transmitting the output signal of the PLC to the controlled equipment, wherein the output type is relay output, transistor output and crystal gate output. Correspondingly, the types of PLC output points also include relay output, transistor output, crystal gate output and the like. Of course, this is merely a specific example, and a microcomputer board or other programmable controller may be used to simulate door lock contacts for practical applications.
In addition, before step 201, the method further includes: it is determined that the elevator is fault-free, that the elevator door lock is in a closed state and that the elevator door lock is not shorted and/or bridged. It will be appreciated that it is necessary to ensure that the elevator and the elevator door lock itself are fault free and in an initial state prior to verification of the elevator door lock detection system.
Step 202, a door opening command is sent to an elevator door lock.
In this embodiment, after a shorting command and/or a bridging command is sent to the elevator door lock, a door opening command needs to be sent to the elevator door lock to ensure that the elevator door lock is automatically opened, and the elevator door lock detection system is automatically triggered to perform door lock abnormality detection.
And 203, acquiring fault information output by the elevator door lock detection system.
And 204, judging whether the elevator door lock detection system is abnormal or not according to a pre-acquired standard fault information table and the fault information.
In this embodiment, according to a standard fault information table and the fault information obtained in advance, determining whether the elevator door lock detection system is abnormal includes: determining fault information corresponding to a command sent to the elevator door lock in the pre-acquired standard fault information table; and when the fault information output by the elevator door lock detection system is inconsistent with the fault information corresponding to the command sent to the elevator door lock, determining that the elevator door lock detection system is abnormal.
Specifically, the content of the corresponding standard fault information table of the elevators of different models is different due to the fact that the elevator door lock loops are different. Such as: after a certain short circuit command is sent to the elevator door lock, the short circuit operation corresponding to the short circuit command is determined, fault information corresponding to the short circuit operation is searched in a standard fault information table corresponding to the elevator, the fault information is compared with the fault information obtained by the elevator door lock detection system, if the fault information is consistent with the fault information obtained by the elevator door lock detection system, the elevator door lock detection system is normal, and if the fault information is inconsistent, the elevator door lock detection system is abnormal.
When judging whether the fault information output by the elevator door lock detection system is consistent with the fault information corresponding to the command sent to the elevator door lock, the consistency judgment comprises two parts: consistency of content and consistency of quantity. Any inconsistency indicates an abnormality in the elevator door lock detection system.
In addition, before step 203, the method further includes: and acquiring a standard fault information table corresponding to the elevator door lock. After step 203, further comprising: and when the elevator door lock detection system is determined to be abnormal, sending alarm information. It can be appreciated that when the elevator door lock detection system is determined to be abnormal, an alarm message can be sent to remind a user to overhaul the elevator door lock detection system. The alarm information comprises fault information of an elevator door lock detection system.
According to the verification method of the elevator door lock detection system, provided by the embodiment of the invention, a short circuit and/or bridging command is sent to the elevator door lock according to the preset door lock detection loop information, so that any door lock fault condition can be automatically simulated, then a door opening command is sent to the elevator door lock, the elevator door lock is guaranteed to be automatically and normally opened, the elevator door lock detection system is automatically triggered to carry out door lock detection, finally, the fault information output by the elevator door lock detection system is obtained, and whether the elevator door lock detection system is abnormal or not can be rapidly judged according to the pre-obtained standard fault information table and the fault information output by the elevator door lock detection system. The whole checking method can check a plurality of elevator door lock detection systems simultaneously, and is simple in operation, high in efficiency and wide in application range.
