Description

Technical Field

[0001] This invention relates to an electrical switch device and its control method, particularly an automatic / manual dual-purpose elevator lock switch and its control method for car elevators. Background Technology

[0002] like Figure 9 As shown, the existing manual elevator lock switch 39 is both a commonly used switch for elevator maintenance and a simple and practical energy-saving switch device. When the elevator is not in use for a fixed period of time, manual locking saves energy, reduces power consumption, and minimizes wear and tear on electronic components. However, locking and unlocking require a dedicated person, which is inconvenient. In daily elevator use, people ride elevators randomly; in fact, the actual daily elevator usage time is less than half, or even less than one-third, thus increasing power consumption and wear and tear on electronic components.

[0003] For escalators with a single operating direction and fixed distance, existing technology using human-sensor elevator lock switches can solve the above problems, achieving dynamic energy saving. However, car elevators have multiple call stations, operate in both vertical and horizontal directions with varying distances, and their usage conditions are complex. The operating direction, distance, and call stations are all random. Even when multiple elevators are in use, the choice of which elevator to use is random. Existing human-sensor elevator lock switches are not suitable for car elevators. Therefore, a dual-purpose automatic / manual elevator lock switch and its control method are needed. This allows for both automatic locking and unlocking using the automatic lock switch to achieve dynamic energy saving, while also providing a convenient way to switch to manual lock operation. Summary of the Invention

[0035] The present invention will be further illustrated below with reference to the embodiments. The embodiments described are only some embodiments of the present invention and are only used to explain the present invention. They do not constitute any limitation on the scope of the present invention.

[0036] The flowchart shown in the attached diagram is for illustrative purposes only and does not necessarily include all content and operations / steps, nor does it necessarily have to be performed in the order described. For example, some operations / steps can be broken down, combined, or partially merged, so the actual execution order may change depending on the actual situation.

[0037] like Figure 1 , Figure 2 As shown, an automatic / manual dual-purpose elevator lock switch includes a human-sensing elevator lock switch consisting of a delayed human body sensor 1 connected to an electronic switch, a manual elevator lock switch 7, and a changeover switch 8, wherein:

[0038] The signal output end 2 of each human body sensor 1 installed in the car or on each floor outside the car is connected with the positive pole of a respective diode 3, the negative pole of each diode 3 is connected with a common wire 4, and the common wire 4 is connected with the signal input end 5 of the automatic lock switch 9 and the mode switching switch 8 between the automatic lock switch 9 and the manual lock switch 7.

[0039] As shown in Figure 1 , Figure 2 In the following embodiments, the length of the common wire 4 is calculated as the maximum running distance of one way x 2 + (10 m-30 m), and the common wire 4 is laid between the top of the car and each floor outside the car.

[0040] As shown in Figure 1 , Figure 2 The common electronic switch 6 is composed of an integrated circuit NOT gate and a relay, or composed of a triode, a diode D1, a relay J1, a resistor R1 and a resistor R2, and the distance between the installation position of the circuit board of the common electronic switch 6 and the position of the manual lock switch 7 is 2 cm-200 cm, and the optimal distance is 10 cm-20 cm.

[0041] The common electronic switch 6 is composed of an integrated circuit NOT gate and a relay, or composed of a triode, a diode D1, a relay J1, a resistor R1 and a resistor R2, and the distance between the installation position of the circuit board of the common electronic switch 6 and the position of the manual lock switch 7 is 2 cm-200 cm, and the optimal distance is 10 cm-20 cm.

[0042] The triode is a NPN switch tube, and the relay J1 is the relay J1 in the automatic lock switch.

[0043] The value range of the resistor R1 is 200 ohms-2000 ohms, and the normal value is 1000 ohms.

[0044] The value range of the resistor R2 is 10 kilo-ohms-100 kilo-ohms, and the normal value is 10 kilo-ohms.

[0045] As shown in Figure 1 , Figure 2 The signal output end 2 of each human body sensor 1 installed in the car or on each floor outside the car is connected with the positive pole of a respective diode 3, the negative pole of each diode 3 is connected with a common wire 4, and the common wire 4 is connected with the signal input end 5 of the automatic lock switch 9 and the mode switching switch 8 between the automatic lock switch 9 and the manual lock switch 7.

[0046] The delay time of the human body sensor 1 in the car or outside the car is calculated as the time required for the maximum running distance of one way under no load x 2 + (40 seconds-180 seconds).

[0047] The time delay human sensor 1 has a time delay range of 60-300 seconds, and the optimal time delay range is 90-210 seconds, and the optimal time delay is 150 seconds.

[0048] Specifically, the human sensor 12 outside the car on each floor is a wake-up sensor for starting the elevator into an automatic unlocking state, and is also a relay sensor for maintaining the automatic unlocking of the elevator in a relay manner.

[0049] The human sensor 12 outside the car on each floor can be installed on the human sensor in the elevator main machine control room.

[0050] Specifically, the human sensor 11 inside the car is a safety sensor for ensuring safe operation of the elevator and maintaining automatic unlocking of the elevator.

[0051] The human sensor 1 is a human infrared sensor or a stationary human detection sensor.

[0052] The advantages of the human infrared sensor are: mature technology, reliable operation, strong anti-electromagnetic interference ability, power saving, and low price.

[0053] The stationary human detection sensor has the characteristics of detecting stationary human infrared signals and accurate detection range, but has poor anti-electromagnetic interference ability and high price.

[0054] One or more human sensors 1 are installed outside the car on each floor, which can be one or more human infrared sensors or one or more stationary human detection sensors.

[0055] Specifically, the human sensor 12 outside the car on each floor is a wake-up sensor and a relay sensor, and the optimal solution is to use two human infrared sensors, and the optimal sensing distance is 5-8 m. The human sensor 12 outside the car is installed on the top of each floor outside the car or on the wall outside the door.

[0056] One or more human sensors 1 are installed inside the car, which can be one or more human infrared sensors or one or more stationary human detection sensors.

[0057] Specifically, the human sensor 11 inside the car is a safety sensor, and the optimal solution is to use two human infrared sensors and one stationary human detection sensor, and the optimal sensing distance is 2.5-4 m. The human sensor 11 inside the car is installed on the top or side wall inside the car.

[0058] As Figures 1-5As shown, the conversion switch 8 for mode switching of the automatic lock ladder switch 9 and the manual lock ladder switch 7 is a mechanical conversion switch or a relay J2 conversion switch. The mechanical switch or the relay J2 conversion switch circuit is installed on the same circuit board with the common electronic switch 6 circuit. The relay J2 conversion switch circuit is a relay J2 conversion switch with a switch K.

[0059] Specifically, when the normally open contact 23 of the manual lock ladder switch 7 is in communication with the common contact 21, it is placed in the manual unlocking position. When the normally closed contact 22 of the manual lock ladder switch 7 is in communication with the common contact 21, it is placed in the manual lock ladder position. The common contact terminal 21 of the manual lock ladder switch 7 is connected to the normally closed contact terminal 19 of the other group of switches 14 of the relay J2 conversion switch.

[0060] The relay J1 of the common electronic switch 6, that is, the relay J1 in the automatic lock ladder switch, is composed of two groups of movable and normally closed switches that can be converted to each other.

[0061] One group of switches 24 is used for the unlocking or locking operation of the automatic lock ladder switch 9 mode.

[0062] The movable contact terminal 28 of one group of switches 24 of the relay J1 in the automatic lock ladder switch 9 is connected to the normally open contact terminal 23 of the manual lock ladder switch 7. The normally closed contact terminal 27 of one group of switches 24 of the relay J1 in the automatic lock ladder switch 9 is connected to the normally closed contact terminal 22 of the manual lock ladder switch 7.

[0063] The common contact terminal 26 of one group of switches 24 of the relay J1 in the automatic lock ladder switch 9 is connected to the movable contact terminal 20 of the other group of switches 14 of the relay J2 conversion switch. The other group of switches 25 is used for collecting data such as automatic unlocking time or automatic locking time.

[0064] The common contact terminal 29 of the other group of switches 25 of the relay J1 in the automatic lock ladder switch 9 is connected to the movable contact terminal 17 of one group of switches 13 of the relay J2 conversion switch.

[0065] The movable contact terminal 31 of the other group of switches 25 of the relay J1 in the automatic lock ladder switch 9 is connected to the input terminal D 38 of the signal processor.

[0066] The normally closed contact terminal 30 of the other group of switches 25 of the relay J1 in the automatic lock ladder switch 9 is connected to the input terminal C 37 of the signal processor.

[0067] The relay J2 conversion switch is composed of two groups of movable and normally closed switches that can be converted to each other.

[0068] One group of switches 13 is used for command signal control of the automatic lock ladder switch 9 or the manual lock ladder switch 7 mode.

[0069] The common contact terminal 15 of the group of switches 13 of the relay J2 change-over switch is connected to the ground 32.

[0070] The normally closed contact terminal 16 of the group of switches 13 of the relay J2 change-over switch is connected to the input terminal A 35 of the signal processor.

[0071] The normally closed contact terminal 16 of the group of switches 13 of the relay J2 change-over switch is connected to the input terminal A 35 of the signal processor.

[0072] The normally closed contact terminal 16 of the group of switches 13 of the relay J2 change-over switch is connected to the input terminal A 35 of the signal processor.

[0073] The normally closed contact terminal 16 of the group of switches 13 of the relay J2 change-over switch is connected to the input terminal A 35 of the signal processor.

[0074] The normally closed contact terminal 16 of the group of switches 13 of the relay J2 change-over switch is connected to the input terminal A 35 of the signal processor.

[0075] The normally closed contact terminal 16 of the group of switches 13 of the relay J2 change-over switch is connected to the input terminal A 35 of the signal processor.

[0076] It is to be noted that the difference between the command of the automatic lock switch 9 mode and the command of the manual lock switch 7 mode is that the stop station of the elevator car is different when the lock switch is in the state.

[0077] When the elevator is automatically locked after the operation command of the automatic lock switch 9 mode is executed, the elevator is stopped at the destination floor when the passenger leaves the elevator, which can further save energy.

[0078] When the elevator is manually locked after the operation command of the manual lock switch 7 mode is executed, the elevator is finally stopped at the base station floor.

[0079] When the command of the automatic lock switch 9 mode is executed, the control system will automatically suspend the execution of the command of the manual lock switch 7 mode, and the command of the automatic lock switch 9 mode is prior to the command of the manual lock switch 7 mode, which further saves energy.

[0080] As shown in Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 7 The change-over switch for switching the mode of the automatic lock switch 9 and the manual lock switch 7.

[0081] The automatic lock switch is powered and the manual lock switch 7 is in the manual lock position, at this time, the automatic lock switch 9 mode is entered. When the manual lock switch 7 is switched, the power needs to be turned off.

[0082] Specifically, when the normally closed contact terminal 22 of the manual lock switch 7 is in communication with the common contact terminal 21, it is in the manual lock position.

[0083] The normally closed contact terminal 22 of the manual lock switch 7 is connected to the common contact terminal 26 of a group of switches 24 in the relay J1 of the automatic lock switch, the normally closed contact terminal 27 of the group of switches 24 is connected to the ground 32, and the normally open contact terminal of the group of switches 24 is connected to the normally open contact terminal of the manual lock switch 7 and then connected to the +Vcc high level.

[0084] It should be noted that when the lock switch is two-wire, the normally open contact terminal of the manual lock switch 7 is connected to the normally open contact terminal of the group of switches 24 in the relay J1 of the automatic lock switch 9 and is suspended.

[0085] The common contact terminal 21 of the manual lock switch 7 is connected to the input terminal G33 of the signal processor or to the PLC interface loop 34.

[0086] It should be noted that after the operation instruction of the automatic lock switch 9 or the manual lock switch 7 mode is executed, the elevator is automatically locked or manually locked, and is stopped at the destination floor when the person leaves the elevator, which is to further save electricity and energy.

[0087] As shown in Figure 1 , Figure 4 , Figure 5 The power supply is an independent power supply E1, and the power supply of the body sensor 11 in the car is a controlled power supply E2.

[0088] Specifically, the automatic lock switch 9 circuit is connected in parallel with the relay J2 conversion switch circuit with a switch K, which can be provided by the elevator main machine control room or by an independent power supply E1, and the negative electrode of the independent power supply E1 is connected to the ground 32.

[0089] The independent power supply E1 connected in parallel with the relay J2 conversion switch circuit with a switch K is connected to the body sensor 12 outside the car and the common electronic switch 6 circuit.

[0090] The power supply of the in-car human sensor 11 is a controlled power supply E2, which is provided by the power supply of the in-car operating box, and the controlled power supply E2 is a controlled power supply E2 with a switch K2, which is a mechanical switch or an electronic switch, the signal input end of the in-car electronic switch is connected with the common conductor, the collector of the transistor in the in-car electronic switch is connected with the negative pole of the in-car human sensor 11, and the emitter of the transistor in the in-car electronic switch is connected with the negative pole of the controlled power supply E2 and the ground.

[0091] The voltage of the independent power supply E1 is 5V-12V, and the optimal voltage is 5V, and the voltage of the controlled power supply E2 is 5V, the negative pole of the independent power supply E1 is connected with the negative pole of the controlled power supply E2, and then connected with the ground 32.

[0092] Since the in-car human sensor 11 adopts the controlled power supply E2, the power-on time of the in-car human sensor 11 can be reduced, the loss of the in-car human sensor 11 can be reduced, and the service life of the in-car human sensor 11 can be prolonged by more than one time.

[0093] The application also provides an automatic / manual dual-purpose lock switch for multiple elevators, which comprises the automatic / manual dual-purpose lock switch.

[0094] As shown in Figure 6 Fig. 1, the signal output end 2 of the one or more human sensors 1 installed in the car of the elevator A 40 and the signal output end 2 of the one or more human sensors 1 installed on each floor outside the car of the elevator A 40 are connected with the positive pole of the respective diode 3, and the negative pole of each diode 3 is connected with the common conductor 4 of the elevator A 40.

[0095] The signal output end 2 of the one or more human sensors 1 installed in the car of each elevator is connected with the positive pole of the respective diode 3, the negative pole of each diode 3 is connected with the common conductor 4 of the respective elevator and communicated, and then connected with the signal input end 5 of the common electronic switch 6 of the respective elevator to form the automatic lock switch 9 of each elevator, and the conversion switch 8 for mode switching between the automatic lock switch 9 and the manual lock switch 7 of each elevator, thereby forming the automatic / manual dual-purpose lock switch of each elevator.

[0096] The common conductors 4 of each elevator are connected and communicated.

[0097] The automatic lock switch 9 of each elevator is formed by the in-car human sensor 11 installed in the car of the elevator and the human sensor 12 installed on each floor outside the car of the elevator A 40 and the common electronic switch 6 of the respective elevator.

[0098] The human sensor 12 installed on each floor outside the car of the elevator A 40 is shared by the automatic lock switch 9 of each elevator.

[0099] The automatic lock switch 9 of each elevator, and the in-elevator human body sensor 11 of other elevators are the relay sensors of the automatic lock switch 9 of each elevator.

[0100] The automatic / manual lock switch of each elevator can work independently, and the number of elevators is 2-8, preferably 2-4.

[0101] The automatic / manual lock switch of each elevator is composed of the automatic lock switch 9 of each elevator, and the mode switching switch 8 of the manual lock switch 7 of each elevator.

[0102] Specifically, the automatic / manual lock switch of each elevator is composed of:

[0103] Taking three elevators as an example, the composition of the automatic / manual lock switch of each elevator is described.

[0104] The composition of the automatic / manual lock switch of the elevator A 40 is as follows:

[0105] The automatic / manual lock switch of the elevator A 40 is composed of the automatic lock switch 9 of the elevator A 40, and the mode switching switch 8 of the manual lock switch 7 of the elevator A 40. Among them:

[0106] The in-elevator human body sensor 11 of the elevator B 41 and the elevator C 42 is the relay sensor when the automatic lock switch 9 of the elevator A 40 works.

[0107] The composition of the automatic / manual lock switch of the elevator B 41 is as follows:

[0108] The automatic / manual lock switch of the elevator B 41 is composed of the automatic lock switch 9 of the elevator B 41, and the mode switching switch 8 of the manual lock switch 7 of the elevator B 41. Among them:

[0109] The in-elevator human body sensor 11 of the elevator A 40 and the elevator C 42 is the relay sensor when the automatic lock switch 9 of the elevator B 41 works.

[0110] The composition of the automatic / manual lock switch of the elevator C 42 is as follows:

[0111] The automatic / manual lock switch of the elevator C 42 is composed of the automatic lock switch of the elevator C 42, and the mode switching switch 8 of the manual lock switch 7 of the elevator C 42. Among them:

[0112] The in-elevator human body sensor 11 of the elevator A 40 and the elevator B 41 is the relay sensor when the automatic lock switch 9 of the elevator C 42 works.

[0113] The automatic / manual dual-purpose lock switch of each elevator can work independently.

[0114] The number of elevators is 2-8, preferably 2-4.

[0115] As Figure 8 shown, the application also provides a control method for an automatic / manual dual-purpose lock switch, comprising the automatic / manual dual-purpose lock switch described above, comprising the following steps:

[0116] S1: Set the appropriate human sensor 1 delay time range and the optimal delay time.

[0117] S2: Enter and maintain the automatic lock switch 9 mode, and the automatic lock switch 9 adopts a multi-point, parallel, relay, and mutual control mode.

[0118] S3: Enter and maintain the automatic unlocking state, and after 2-3 seconds, the elevator enters and maintains the automatic running working state.

[0119] S4: Enter and maintain the automatic lock state, and the elevator enters and maintains the standby sleep state, dynamically saving power and energy.

[0120] S5: Recursively execute the operation steps of S3 and S4 to continuously repeat the process of automatic unlocking and automatic locking.

[0121] S6: Enter and maintain the manual lock switch 7 mode, and manual unlocking and locking operations can be performed.

[0122] S7: Enter and maintain the manual unlocking state, and after 2-3 seconds, the elevator enters and maintains the automatic running working state.

[0123] S8: Enter and maintain the manual lock state, and the elevator enters and maintains the standby sleep state.

[0124] Further, step S1 comprises the following steps:

[0125] S11: The human sensor 1 delay time range is calculated as the single-trip empty maximum running distance required time × 2 + (40-180 seconds).

[0126] According to the elevator design requirements, the single-trip empty maximum running distance required time is less than 60 seconds, and for convenience of calculation, the single-trip minimum time is 10 seconds, the single-trip maximum time is 60 seconds, and the delay time is (10-60) seconds × 2 + (40-180 seconds) = (60-300) seconds.

[0127] S12: The human sensor 1 delay time range is 60-300 seconds.

[0128] The optimal delay time range is 90-210 seconds.

[0129] The best delay time is 150 seconds;

[0130] It is necessary to explain the purpose of setting 150 seconds delay for the human sensor 1.

[0131] Since the signal output end 2 of each human sensor 1 and the signal output end 5 of the triode electrode in the common electronic switch 6 constitute a NAND gate, when a person enters the sensing area of any human sensor 1, the signal output end 2 of the human sensor 1 is high, the signal output end 10 of the triode collector electrode in the common electronic switch 6 is low, and remains for 150 seconds, then the relay J1 in the common electronic switch 6 acts for 150 seconds, which ensures that any human sensor 1 can independently complete the time required for the maximum running distance of the elevator in the empty load of the double journey.

[0132] As long as a person walks into the sensing area of the human sensor 1, the relay J1 in the common electronic switch 6 acts for 150 seconds, that is, the automatic lock switch keeps acting for 150 seconds.

[0133] When the person walks out of the sensing area, the relay J1 in the common electronic switch 6 renews the holding action time for 150 seconds, that is, the automatic lock switch renews the holding action time for 150 seconds. In addition,

[0134] ① Since the human infrared sensor adopts a repeated trigger mode, it can be repeatedly triggered.

[0135] ② The static human detection sensor has the feature that it remains for 150 seconds of time delay until the person walks out of the sensing area.

[0136] Therefore, when a person walks into or walks out of the sensing area of the human sensor 1, the relay J1 in the common electronic switch 6 can act for 150 seconds, that is, the automatic lock switch can act for 150 seconds.

[0137] Among them, step S2 includes the following steps:

[0138] S21: Turn on the switch K, and the manual lock switch 7 is placed in the manual unlocking position, and the relay J2 switch acts, then automatically switch to the automatic lock switch 9 mode,

[0139] After the relay J2 switch acts, the movable and fixed contact terminals of the two sets of switches are respectively connected to the common contact terminals.

[0140] S22: The movable and fixed contact terminals 17 of the one set of switch 13 are connected to the common contact terminals 15, which are used for the instruction signal control of the automatic lock switch 9 mode:

[0141] The common contact terminal 15 of the one set of switch 13 in the relay J2 switch is connected to the ground 32,

[0142] The moving contact terminal 17 of the set of switches 13 is in communication with the common contact terminal 15, which is connected to the input terminal B 36 of the signal processor for executing the instruction of the automatic door lock switch 9 mode.

[0143] S23: The moving contact terminal 20 of the other set of switches 14 is in communication with the common contact terminal 18 for the unlocking or locking operation of the automatic door lock switch 9 mode.

[0144] The relay J2 converts the common contact terminal 18 of the other set of switches 14 into communication with the moving contact terminal 20, and is connected to the common contact terminal 26 of the set of switches 24 of the relay J1 in the automatic door lock switch 9, and is further connected to the signal processor G 33 or the PLC interface circuit 34.

[0145] S24: As shown in the figure, the automatic door lock switch 9 adopts a multi-point, parallel, relay, mutual control mode to enter and maintain the automatic unlocking state, and achieves dynamic power saving through the automatic door lock, and the specific structure is as follows: Figure 2

[0146] S25: The signal output end 2 of each human body sensor 1 and the signal output end 10 of the common electronic switch 6 form an AND gate circuit.

[0147] The relay J1 in the common electronic switch 6 is the relay J1 in the automatic door lock switch 9.

[0148] The working principle of the AND gate circuit is that when a person walks into the sensing area of any human body sensor 1, the relay J1 in the automatic door lock switch 9 is actuated, and the elevator is automatically unlocked.

[0149] The automatic door lock switch 9 enters and maintains the automatic unlocking of the elevator through the multi-point, parallel, relay, mutual control mode of the signal output end 2 of the human body sensor 1.

[0150] S26: When the signal output end of each human body sensor 1 does not output a signal, i.e., all are low, the relay J1 in the automatic door lock switch 9 is released and does not actuate, and the elevator is automatically locked.

[0151] In the embodiment of the application, step S3 comprises the following steps:

[0152] S31: When a person walks into the sensing area of any human body sensor 1 outside the car, the relay J1 in the automatic door lock switch 9 is switched and actuated to start the automatic unlocking of the elevator, and after 2-3 seconds, the elevator enters and maintains the automatic running state, and the human body sensor outside the car enters and maintains the automatic unlocking state through the random relay mode, the human body sensor 12 of each floor outside the car is a wake-up sensor and a relay sensor, and the human body sensor 11 inside the car is a safety sensor. ​

[0153] When the relay J1 of the automatic lock switch 9 is actuated, the normally closed contact terminal 23 of the manual lock switch 7 is connected to the normally open contact terminal 22 of the relay J1.

[0154] S32: The normally open contact terminal 28 of the one group switch 24 is connected to the normally closed contact terminal 26 of the relay J1 of the automatic lock switch 9, so as to enter and keep the automatic lock state.

[0155] The normally open contact terminal 28 of the one group switch 24 of the relay J1 of the automatic lock switch 9 is connected to the normally closed contact terminal 23 of the manual lock switch 7.

[0156] The normally open contact terminal 20 of the another group switch 14 of the relay J2 switch is connected to the normally closed contact terminal 18, and is connected to the normally open contact terminal 28 of the one group switch 24 of the relay J1 of the automatic lock switch 9, and is connected to the input terminal G 33 of the signal processor, or is connected to the PLC interface circuit 34.

[0157] Therefore, the automatic lock switch 9 enters and keeps the automatic lock state, and the elevator enters and keeps the automatic operation state after 2 to 3 seconds.

[0158] S33: The normally open contact terminal 31 of the another group switch 25 is connected to the normally closed contact terminal 29, so as to collect the data of the automatic lock time, and can also be used as a circuit control switch.

[0159] The normally open contact terminal 17 of the one group switch 13 of the relay J2 switch is connected to the normally closed contact terminal 15, and is connected to the normally open contact terminal 31 of the another group switch 25 of the relay J1 of the automatic lock switch 9.

[0160] The normally closed contact terminal 15 of the one group switch 13 of the relay J2 switch is connected to the ground 32.

[0161] The normally open contact terminal 31 of the another group switch 25 of the relay J1 of the automatic lock switch 9 is connected to the input terminal D 38 of the signal processor.

[0162] The another group switch 25 of the relay J1 of the automatic lock switch 9 is used to collect the data of the automatic lock time, and can also be used as a power switch to control the related circuits in the host control room and the car.

[0163] It should be noted that the signal output terminal 2 of each human body sensor 1 and the signal output terminal 10 of the common electronic switch 6 constitute an AND gate. When a person walks into or out of the sensing area of any human body sensor 1, the actuation time of the relay J1 of the automatic lock switch 9 is kept for 150 seconds, that is, the automatic lock switch 9 keeps the automatic lock time for 150 seconds.

[0164] The function of the human body sensor 12 outside the car is to start the automatic lock switch 9 to enter the automatic lock and keep for 150 seconds, so the human body sensor 12 outside the car is a wake-up sensor and a relay sensor.

[0165] The function of the human body sensor 11 inside the car is to ensure the safe operation of the elevator and keep the safety sensor in the automatic lock state.

[0166] Generally, the time required from when a person walks into the car to when a person walks out of the car is within 60 seconds.

[0167] In the embodiment of the application, step S4 comprises the following steps:

[0168] S41: When a person walks out of the car for 150 seconds and no one uses the elevator, the signal output end 2 of each human body sensor 1 has no signal output, i.e., is at a low level, the relay J1 of the automatic lock switch 9 is released and does not act, and enters and keeps the automatic lock state.

[0169] After the relay J1 of the automatic lock switch 9 is released and does not act, the normally closed contact terminals of the two groups of switches are respectively connected to the common contact terminals.

[0170] S42: The normally closed contact terminals 27 of the one group of switches 24 are connected to the common contact terminals 26 for entering and keeping the automatic lock state.

[0171] The normally closed contact terminals 27 of the one group of switches 24 of the relay J1 of the automatic lock switch 9 are connected to the normally open contact terminals 22 of the manual lock switch 7.

[0172] The common contact terminals 18 of the other group of switches 14 in the relay J2 change-over switch are connected to the normally closed contact terminals 20.

[0173] And the normally closed contact terminals 27 of the one group of switches 24 of the relay J1 of the automatic lock switch 9 are connected to the common contact terminals 26 and are connected to the input terminals G33 of the signal processor or are connected to the PLC interface circuit 34.

[0174] Therefore, the automatic lock switch 9 enters and keeps the automatic lock state, the elevator enters and keeps the standby sleep state, and dynamic power saving is achieved.

[0175] S43: The common contact terminals 29 of the other group of switches 25 are connected to the normally closed contact terminals 30 for collecting automatic lock time and other data, and can also be used as a control switch of other circuits.

[0176] The normally closed contact terminals 17 of the one group of switches 13 in the relay J2 change-over switch are connected to the common contact terminals 15,

[0177] And the normally closed contact terminal 30 of the other group of switches 25 in the automatic lock switch 9 relay J1 is in communication with the common contact terminal 29 and connected.

[0179] And the normally closed contact terminal 30 of the other group of switches 25 in the automatic lock switch 9 relay J1 is connected to the input terminal C 37 of the signal processor.

[0180] The automatic lock switch 9 is used to collect the time and other data of the automatic lock, and also used as a power switch to control the related circuits in the car and the main control room, so as to save power.

[0181] In the embodiment of the application, step S5 comprises the following steps:

[0183] S52: The automatic lock switch 9 randomly and repeatedly performs the operation steps S3 and S4 to repeatedly perform the automatic unlocking and automatic locking processes.

[0184] In the embodiment of the application, step S6 comprises the following steps:

[0188] The common contact terminal 15 of the one group of switches 13 is connected to the ground 32.

[0189] The normally closed contact terminal 16 of the one group of switches 13 is in communication with the common contact terminal 15, and connected to the input terminal A 35 of the signal processor, and used for the instruction of the manual lock switch 7 mode.

[0190] S63: The normally closed contact terminal 19 of the other group of switches 14 is in communication with the common contact terminal 18, and used for the unlocking or locking operation of the manual lock switch 7 mode.

[0191] The static contact terminal 19 of the other group of switches 14 of the relay J2 changeover switch is in communication with the common contact terminal 18 and is connected to the common contact terminal 21 of the manual lock switch 7 and is further connected to the input terminal G 33 of the signal processor or to the PLC interface circuit 34.

[0192] S64: The manual lock switch 7 mode is entered and maintained, and manual unlocking and locking operations can be performed.

[0193] In the embodiment of the application, step S7 comprises the following steps:

[0195] S72: The normally open contact terminal 23 of the manual lock switch 7 is in communication with the common contact terminal 21, that is, has been placed in the manual unlocking position, and is used for entering and maintaining the manual unlocking state.

[0196] The common contact terminal 21 of the manual lock switch 7 is in communication with the normally open contact terminal 23 and is in communication with the static contact terminal 19 of the other group of switches 14 of the relay J2 changeover switch and is connected, and is further connected to the input terminal 33 of the signal processor or to the PLC interface circuit 34.

[0197] At this time, the manual unlocking state is entered and maintained, and after 2-3 seconds, the elevator enters and maintains the automatic operation working state.

[0198] In the embodiment of the application, step S8 comprises the following steps:

[0199] S81: The relay J2 changeover switch is released from inaction, and the static contact terminal 19 of the other group of switches 14 is in communication with the common contact terminal 18 and is used for unlocking or locking operations in the manual lock switch 7 mode.

[0200] S82: The normally closed contact terminal 22 of the manual lock switch 7 is in communication with the common contact terminal 21, that is, has been placed in the manual locking position, and is used for entering and maintaining the manual locking state.

[0201] The normally closed contact terminal 22 of the manual lock switch 7 is connected to the ground 32.

[0202] The normally closed contact terminal 22 of the manual lock switch 7 is in communication with the common contact terminal 21, that is, has been placed in the manual locking position, and is in communication with the static contact terminal 19 of the other group of switches 14 of the relay J2 changeover switch and is connected, and is further connected to the input terminal 33 of the signal processor or to the PLC interface circuit 34.

[0203] At this time, the artificial lock ladder state is entered and maintained, and the elevator enters and maintains the standby sleep state.

[0204] It should be noted that the above-mentioned embodiment is that the artificial lock ladder switch 7 is realized under the following wiring connection conditions.

[0205] The artificial lock ladder switch 7 mode, the common contact terminal 21 of the artificial lock ladder switch 7 is connected with the static contact terminal 19 of the other group of switches 14 of the relay J2 conversion switch, and the static contact terminal 19 is communicated with the common contact terminal 18, and then connected with the input terminal G33 of the signal processor or connected in the PLC interface loop 34. At this time, the elevator enters the artificial lock ladder switch 7 mode, and the artificial lock ladder switch 7 mode can be operated.

[0206] The artificial lock ladder refers to that the artificial lock ladder switch 7 is placed in the artificial lock ladder position, that is, the normally closed contact terminal 22 of the artificial lock ladder switch 7 is communicated with the common contact terminal 21, and the normally closed contact terminal 22 is connected with the ground 32.

[0207] The artificial lock ladder refers to that the artificial lock ladder switch 7 is placed in the artificial lock ladder position, that is, the normally closed contact terminal 22 of the artificial lock ladder switch 7 is communicated with the common contact terminal 21, and the normally closed contact terminal 22 is connected with the ground 32.

[0208] When the artificial lock ladder switch 7 is three-wire, the normally open contact terminal 23 is high level.

[0209] When the artificial lock ladder switch 7 is two-wire, the normally open contact terminal 23 is suspended.

[0210] In the embodiment of the application, the working principle of the automatic lock ladder switch is:

[0211] Referring to Figure 1 , Figure 2 As shown in the figure, the signal output end 2 of each human body sensor 1 and the signal output end 10 of the common electronic switch 6 constitute an or non gate, and the relay J1 of the common electronic switch 6 is the relay J1 of the automatic lock ladder switch. As can be known from the working principle of the or non gate circuit, as long as the signal output end 2 of any human body sensor 1 is high level, the signal output end 10 of the common electronic switch 6 is low level, and the relay J1 will act, that is, the relay J1 of the automatic lock ladder switch 9 acts, and the elevator is automatically unlocked. Therefore, the automatic lock ladder switch 9 enters and maintains the automatic unlocking of the elevator through the multi-point, parallel, relay and mutual control mode.

[0212] When the signal output end 2 of each human body sensor 1 does not output signal, i.e. is low level, the signal output end 10 of the transistor collector of the common electronic switch 6 is high level, and the relay J1 is released and does not act, i.e. the relay J1 of the automatic lock switch 9 is released and does not act, and the elevator is automatically locked, thereby achieving dynamic power saving, reducing power consumption and reducing electronic component loss.

[0213] The human body sensor 1 is an infrared human body sensor, the delay time is set to 150 seconds, the repeated triggering mode is adopted, and there is only one infrared human body sensor on each floor inside and outside the car. In addition, according to the design requirements of the elevator, the maximum running distance required by a single empty load is less than 60 seconds.

[0214] The working principle of the automatic lock switch will be further described in detail.

[0215] When a person walks into the sensing area of any infrared human body sensor, the signal output end 2 of the sensor is high level, and the high level output maintains for 150 seconds. The signal output end 10 of the transistor collector of the common electronic switch 6 is low level, and the low level output maintains for 150 seconds. Therefore, the action time of the relay J1 of the common electronic switch 6 is 150 seconds, i.e. the automatic unlocking time of the automatic lock switch is 150 seconds.

[0216] Therefore, the high level output time of the signal output end 2 of any infrared human body sensor can independently complete the time required by the maximum running distance of a single empty load of the elevator.

[0217] The function of the infrared human body sensor on each floor outside the car is to start the wake-up sensor of the automatic unlocking of the elevator, and it is also a relay sensor to maintain the automatic unlocking state of the elevator.

[0218] The human body sensor 12 on each floor outside the car randomly passes through each point in a relay mode, and is connected in parallel with the human body sensor 11 inside the car in a mutual control mode, enters and maintains the automatic unlocking state, and makes the elevator enter and maintain the automatic running working state.

[0219] The function of the infrared human body sensor inside the car is to ensure that when a person is in the car, the safety sensor of the elevator maintains the automatic unlocking state, and makes the elevator maintain the automatic running working state.

[0220] Because of the repeated trigger mode, when a person walks out of or into the car, the high level output time of the sensor signal output end 2 is restored to the set delay time of 150 seconds. Therefore, as long as there is a person in the elevator car, the in-car human body sensor 11 keeps its signal output end high level, until the last person walks out of the elevator, and the high level output time of the sensor signal output end 11 is restored to the set delay time of 150 seconds. Therefore, the automatic lock switch always keeps the automatic unlocking state, and the elevator always keeps the automatic running working state.

[0221] The automatic lock switch 9 mode is entered and maintained; the power switch is turned on, and the manual lock switch 7 is placed in the manual unlocking position, and the relay J2 changeover switch is actuated to automatically switch to the automatic lock switch 9 mode.

[0222] Further details of the working principle of automatic unlocking are as follows:

[0223] When a person walks into the sensing area of the in-car human body infrared sensor, the automatic lock switch 9 is actuated to start and maintain the automatic unlocking of the elevator, and after 2-3 seconds, the elevator enters and maintains the automatic running working state.

[0224] When a person walks into the elevator car, the high level output time of the in-car human body infrared sensor signal output end 2 is maintained for 150 seconds, and every time a person walks out of or into the car, the high level output time of the in-car sensor signal output end 2 is constantly restored to 150 seconds, until the last person walks out of the car, and the high level output time of the in-car sensor signal output end 2 is restored to 150 seconds.

[0225] It should be noted that if a stationary human body detection sensor is used in the car, the high level output time of the sensor signal output end 2 will still be maintained for 150 seconds until the last person walks out of the car.

[0226] If a person uses the elevator within 150 seconds, the automatic lock switch always keeps the automatic unlocking state, and therefore the elevator always keeps the automatic running working state.

[0227] At the same time, the out-of-car human body sensors 12 randomly pass through each point and relay mode, and are connected in parallel with the in-car human body sensor 11 in a mutual control mode to enter and maintain the automatic unlocking state, so that the elevator enters and maintains the automatic running working state.

[0228] When the automatic lock elevator state is entered and maintained, a person leaves the elevator for 150 seconds, and no one takes the elevator. At this time, the signal output end 2 of each human body infrared sensor inside and outside the car has no output signal, i.e. is low level, and the signal output end 10 of the transistor in the common electronic switch 6 is high level. Therefore, the relay J1 switch in the automatic lock elevator switch 9 is released and does not act, i.e. the automatic lock elevator switch 9 is released and does not act, and the elevator is automatically locked, achieving dynamic power saving.

[0229] Since people take the elevator randomly, the automatic lock elevator switch 9 repeatedly performs the above automatic unlocking and automatic locking process.

[0230] The manual lock elevator switch 7 mode is entered and maintained, the switch K is turned off, and the relay J2 transfer switch automatically switches to the manual lock elevator switch 7 mode.

[0231] The manual unlocking state is entered and maintained. Since the manual lock elevator switch 7 has been placed in the manual unlocking position, the manual lock elevator switch 7 enters and maintains the manual unlocking state, and the elevator enters and maintains the automatic running working state.

[0232] At this time, according to the actual situation, the manual lock elevator switch 7 can maintain the manual unlocking state or perform the manual lock elevator operation.

[0233] The above is only a preferred embodiment of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application should be included in the protection scope of the present application.
