This disclosure relates to a hydraulic excavator and its hour counter anti-tampering method and system, as well as an electronic monitor. The anti-tampering method for the hydraulic excavator hour counter includes: when the hour counter count changes, the electronic monitor determines whether there is suspicious activity in the hour counter; if suspicious activity is found, the electronic monitor actively drives the engine speed to change, wherein the engine of the hydraulic excavator is a mechanical engine; the electronic monitor acquires the current engine speed; the electronic monitor determines whether the current engine speed is consistent with a set speed; if the current engine speed is inconsistent with the set speed, the electronic monitor determines that the current hour counter count is a first invalid count. This disclosure can achieve anti-tampering of the hour counter of a hydraulic excavator based on a mechanical engine, effectively preventing the hour counter from being tampered with.

The application discloses a pipe hoisting machine based on an excavator chassis, which comprises an excavator chassis, an excavator working platform, a pipe hoisting machine working device, a rotating mechanism, a chassis horizontal inclination sensor, a rotating angle detection element, a hoisting arm angle sensor, a pin shaft sensor, an electronic monitor and a controller. The controller is connected with the chassis horizontal inclination sensor, the rotating angle detection element, the hoisting arm angle sensor, the pin shaft sensor and the electronic monitor. The working posture of the whole machine is judged by collecting the data of the horizontal inclination sensor and the rotating angle detection element. The lifting performance table under the current working condition is called according to the hoisting arm angle sensor, the pipe hoisting operation is implemented, the pin shaft sensor feedback data is collected to detect whether the construction is safe under the condition, and whether the pipe hoisting machine working device works is controlled according to the judgment result, so that the safe pipe hoisting construction on the slope is realized. The control principle of the application is simple and reliable, and is suitable for industrialization popularization and application.

The invention discloses a single-proximity-switch bidirectional buffer limiting system and a control method. A limiting enabling switch, a proximity switch, an A-direction motion detection module, a B-direction motion detection module, an A-direction motion speed regulation module, a B-direction motion speed regulation module and an electronic monitor are in signal connection with a controller; the limiting enabling switch is used for controlling the opening and closing of a limiting function; the proximity switch is used for transmitting the detection state of the proximity switch to the controller in the movement process; the A-direction motion detection module and the B-direction motion detection module are used for detecting the motion operation direction of equipment or parts; the controller further comprises a counter which is used for recording the position of the proximity switch and the movement limiting state of equipment or parts. The A-direction movement speed regulation module and the B-direction movement speed regulation module are used for movement buffering control and limiting control; the electronic monitor is used for operation and fault reminding. Two proximity switch detection points are respectively arranged in two directions, and high-speed motion buffering and high-speed accurate position limiting are realized by adopting an FSM control algorithm.

In recent years, people pay more and more attention to self health monitoring management, and wearable intelligent electronic products with various forms such as a bracelet, a finger ring, a watch and a finger clip and monitoring functions of heart rate, blood oxygen, motion recording and positioning are successively marketed, so that daily health monitoring of people is greatly facilitated; although the existing first-aid medicine box technology solves the problem that medicines are carried about to realize hand-lifting medicine feeding, the function is single, and the intelligent health monitor connected in series on the watchband of the watch comprises an electronic monitor and a connecting device, brand new electronic health monitoring equipment can be formed after the connecting devices at the two ends of the electronic monitor are connected with the watch or the watchband in a matched mode, the intelligent health monitor connected to the watchband of the watch in series is matched with any watches, personalized use of a user is facilitated, carry-on wearing is strengthened, and the intelligent health monitor is used for daily health monitoring of people and also can be used for health monitoring of people. The watch can also be used together with a wristwatch first-aid box, and first aid can be carried out at any time in emergency, so that the watch has more functions.

The application provides a control method and system of an air conditioning system, the control method comprising the following steps: obtaining high-pressure side refrigerant pressure and low-pressure side refrigerant pressure of a compressor of the air conditioning system; judging an operation state of the air conditioning system according to the high-pressure side refrigerant pressure and the low-pressure side refrigerant pressure of the compressor; and controlling the operation of the air conditioning system according to the operation state of the compressor. The method detects pressure sensor pressure signals and feeds back to an electronic monitor, and the electronic monitor judges whether the high-pressure side pressure and the low-pressure side pressure are in a normal range. In the case that a refrigeration switch is opened, the low-pressure side pressure is abnormally increased, the high-pressure side pressure is abnormally decreased, the electronic monitor alarms, and a clutch electromagnet is automatically disconnected, so that the driver can continue to work and repair at a proper opportunity, and a belt breakage or even a more serious accident caused by the compressor seizure can be avoided.

A smart health monitor connected in series to a watch strap of a watch, comprising an electronic monitor (1) and connecting apparatuses, wherein the connecting apparatuses at two ends of the electronic monitor (1) can be adaptively connected to a watch (12) or a watch strap (8) to constitute a novel electronic health monitoring device. The smart health monitor connected in series to a watch strap of a watch is adapted to any watch, so as to facilitate personalized use by a user and enhance the wearability. In addition to being used for daily health monitoring of people, the smart health monitor can further be used in conjunction with a wristwatch first-aid kit to provide first aid at any time in case of an emergency, thereby endowing the watch with more functions.

The application discloses a kind of excavator engine coupling control device and method, comprising: including mutually electrically connected main controller, switch control unit and engine controller;The main controller and switch control unit, main controller and engine controller are connected by bus respectively;Electronic monitor, emergency stop switch and emergency mode relay are connected on the main controller;By adopting power-on and start-stop switch independent design, realize power control and engine start-stop separation control, further through controller coupling start-stop, the intelligentization of start-stop control is realized, and the system can also be controlled by controller coupling flameout to realize the purpose that system key switch control electricity is uninterrupted when flameout;When controller fails, power supply and starting circuit can be switched by the contact state conversion of safety relay, and the starting circuit can be switched from coupling control to direct control by emergency mode relay, to improve the reliability of start-stop control system.
